Domestic support for farmers in high-income economies also hurts developing country exporters to the extent that it boosts domestic production, depresses world prices, exacerbates the volatility of world prices and reduces the scope for import competition. High tariffs and domestic support policies may, however, benefit net importers of agriculture products in developing countries by providing access to the subsidized commodities at lower prices.' Thus, as is well known, national interests regarding reform of OECD agricultural trade and support policies will differ. However, most analyses conclude that the overall gain to developing countries from reforming agricultural policies greatly outweighs the potential costs to countries that are significant net importers of subsidized agricultural products. Starting in 2000, negotiations were launched in the WTO to further reduce intervention in agricultural markets. These negotiations focus on both subsidy policies and border protection (tariffs and tariff rate quotas). An important policy question confronting developing countries is to determine which instruments of agricultural protection are most detrimental to their interests. In this paper we attempt to shed some light on this issue by assessing the relative impact of tariffs and domestic support policies on exports and welfare of developing countries. Specifically, we assess the impact of a 50 percent global reduction in agricultural tariffs and compare this to a 50 percent cut in domestic support.2 Our objective is to assess where negotiating efforts in the context of the current WTO negotiations on agriculture might be best directed. We find that in welfare terms, tariffs matter significantly mnore than subsidy policies- tariff reductions generate welfare gains that are substantially greater than reductions in support policies.3 In large part this is because of high tariff peaks in OECD countries and because developing countries also use iariffs to protect domestic production. As is almost always the case, when it comes to trade policy reform, the principle 'what you do determines what you get' applies. This does not imply that negotiations should therefore emphasize tariffs over domestic ' This potential national welfare benefit is offset by the higher price volatility created by support policies as country specific shocks may be transferred to world markets. In this paper we ignore the extent to which price volatility is transmitted to world markets. 2 The policy simulation can be motivated by a conservative interpretation of the Doha declaration: "....we commit ourselves to comprehensive negotiations aimed at: substantial improvements in market access, reduction of, with a view to phasing out, all forms of export subsidies; and substantial reductions in trade-distorting domestic support" (WTO Doha Ministerial Declaration, para 13, November 2001). support policies. A major political economy problem confronting WTO negotiators is to create incentives for countries to liberalize agricultural trade. Many observers oppose further agricultural trade liberalization in an environment that is characterized by continued large-scale support for OECD farmers. Past experience has demonstrated that the gains from own liberalization may be attenuated because of the market segmenting effect of OECD subsidy policies, and in some instances-e.g., India-liberalization proved to be politically unsustainable as farmers are subjected to large world price swings and import surges of subsidized commodities (Gulati and Narayanan, 2002). Substantial reduction in OECD agricultural support policies is therefore not just important for developing countries in its own right-in that it generates direct benefits for the many economies that are (potential) net exporters-but is critical to support efforts by developing country governments to pursue domestic reforms. That is, subsidy reforms in OECD countries are necessary, but not sufficient, for developing countries to reap significant gains from the current WTO negotiations on agriculture. In contrast to many quantitative analyses of the effects of agricultural trade policies, we use a partial equilibrium framework to estimate the impact of policy changes for a sample of 119 countries on world prices of agricultural commodities that benefit from domestic support in at least one WTO member. We limit the analysis to products that benefit from domestic support in order not to bias our findings. Because most countries apply tariffs to all agricultural products, not just those that are subsidized, any comparison of the effect of reducing tariffs on all agricultural goods with a reduction in support policies would conclude that tariffs are more important for developing countries. The partial equilibrium approach allows us to assess the effects of policy changes on individual countries, including low income and least developed economies that are of particular concern to the development community. The majority of these countries are generally subsumed in regional aggregates in applied general equilibrium models. The partial equilibrium approach also allows us to use disaggregated trade and protection data- we work at the 6-digit level of the Harmonized System.4 3 Note that export subsidies are left outside the analysis but these are relatively small as they represent only 8-10 percent of total domestic support. 4 For recent CGE studies focusing on the same question see Beghin, Roland-Hoist and van der Mensbrugghe (2002), Dimaranan, Hertel and Keeney (2002) and Rae and Strutt (2002). These studies obtain qualitatively similar results (i.e., border barriers matter more than domestic support). 2 2 Tariffs and domestic support in agriculture Agricultural products are often subject to tariff peaks that are 100 percent or higher (Hoekman, Ng and Olarreaga, 2002). The average MFN tariff that is applied to agricultural products varies substantially across countries, but in the majority of OECD cowatries is more than double the average that applies for manufactures. In addition to tariffs, many high-income countries subsidize domestic agriculture. WTO data indicate that there are 158 commodities at the 6-digit level of the Harmonized System (HS) that benefit from domestic support in at least one WTO member. Large-scale use of domestic support is primarily founcl in OECD countries, especially the EU, Japan and the United States. Industrialized countries account for 88 percent of total domestic support payments; if South Korea and transition economies such as Poland are excluded, developing countries account for only 10 percent of total support reported to the WTO during 1995-6 (Table 1). Major subsidizers among developing countries include Brazil, Thailand and Venezuela. Not surprisingly, least developed countries (LDCs) report virtually no domestic support. Meat, dairy, cereals and sugar account for the lion's share of domestic support, representing almost 75 percent of all reported non-exempt domestic support (WTO categories DS4-9) (Table 2). The average tariff on these subsidized products is around 18 percent, -with peaks in the 100-200 percent range for many countries (Table 3). Average tariffs are relatively uniformly distributed across major product categories, with the highest applying in dairy and sugar (and alcoholic beverages-a special case given use of tariffs for revenue and cultural purposes) (Table 4). These are also the sectors that have the highest levels of domestic support. A number of countries make intensive use of specific tariffs for agricultural imports. One consequence of this is that statutory average ad valorem MFN tariffs understate the level of tariff protection, especially for the EU and Japan.5 In this paper we use estimates of ad valorein equivalents of specific tariffs for the 158 tariff lines on which the analysis focuses, drawing on data reported in Stawowy (2001) and OECD (2000) at the tariff line level. Given that estimates of ad valorem equivalents for Switzerland are incomplete and unreliable, we have excluded this country from the analysis (Switzerland relies almost completely on specific tariffs). The global pattern of protection and support to agriculture will have differential impacts on countries depending on whether they are net producers or consumers of the commodities 5 Fontagne et al. (2002) report that the EU, Japan and the US have 1,059, 418 and 1,148 six-digit tariff lines that are subject to specific tariffs. 3 affected. A first cut at identifying the likely implications of protectionist policies for individual countries is to calculate the relative importance of exports and imports of the products that are subsidized by at least one WTO member. Such data reveal that LDCs are potentially much more affected than other countries: 18 percent of their exports on average comprise goods that are subsidized in at least one WTO member, compared to 3-4 percent for other countries (Table 5). A similar observation holds for imports-nine percent of LDC imports involve products that are subsidized, compared to 3-4 percent for other countries. For many LDCs the potential incidence of subsidies is therefore very high. Indeed, for countries such as Benin, Burkina Faso, Burundi, Chad, Malawi, Mali, Rwanda, Sudan, Tanzania, Uganda and Zimbabwe, 60 to 80 percent of total exports comprise goods that are subsidized by one or more WTO members. Given that these are also countries that tend to have preferential-mostly duty-free-access to the European market (through the GSP and Everything But Arms initiative), this suggests subsidies are an important issue for WTO negotiations (as subsidies are not covered by preferential access agreements).6 However, this ignores the depressing effects of tariffs by major WTO members on world prices, as well as the impact of own tariffs-issues that are explored empirically below. Table 5 also identifies countries where the ratio of imports of subsidized goods to total imports is higher than the ratio of "affected" exports to total exports. In such cases it is possible that global liberalization may have short run negative effects on the terms of trade and/or welfare insofar as the prices of imports are lowered because of subsidies. Countries where the balance is tilted towards imports of subsidized commodities comprise countries at very different levels of per capita incomes. They include Bangladesh, Comoros, Egypt, Gambia, Guinea, Jordan, Korea, Maldives, Mauritania, Morocco, Nigeria, Oman, Saudi Arabia, Senegal, Taiwan, Tunisia and Venezuela. The agricultural domestic support numbers reported to the WTO comprise a mix of instruments and measures. The major distinction that is made is between measures that are exempted from WTO reduction commitments under the Uruguay Round Agreement on Agriculture and those that are not. The former include so-called green box support, measures whose use is permitted for developing countries and payments under production limiting 6 It is difficult to assess to which extent EBA offers actual preferential access to LDCs as rules of origin and other non-tariff barriers may actually erode the preferential access granted on paper. In the case of the US initiative for Sub-Saharan Africa (AGOA), there is data made publicly available on the actual gains for African countries and these tend to be small (Mattoo, Roy and Subramanian, 2002). In the case of Europe, Brenton and Manchin (2002) show evidence that EU preferential access schemes have offered limited benefits due to restrictive rules of origin. 4 programs (including the blue box).7 The latter include measures that are deemed to directly support production. As our interest in this paper is to compare the effect of border protection (tariffs) with domestic subsidy-type support on a product-by-product basis, we use the WTO Aggregate Measure of Support (AMS) data, as this does not include the effect of border barriers. We recognize that there are a number of limitations associated with the AMS data. One problem is that the time period for which data are available is short and reporting is incomplete, especially for more recent years. This is discussed further in the data annex. Another problem is that the economic relevance of the AMS time series is limited given the use of the fixed 1986-88 benchmark for purposes of calculating price support. However, given that the econometric and simulation work is done for one point in time (the average for 1995-1998), this should be less of a problem in this paper. 3 Analytical framework To estimate the impact that a reduction in tariffs and/or domestic support may have on exports and welfare we use a simple partial equilibrium model. World markets are assumed to be perfectly competitive and integrated, in the sense that'there-is no further scope for arbitrage across countries. Products traded in world markets under the same 6-digit F[S classification are considered to be perfectly homogenous.9 Each 6-digit HS product category represents only a small share of the economy, so that the effect on other product markets of changes in a particular category is negligible.'0 Import demand for each HS-6-digit product of country c is given by: aC ~~~~~~~~~~~~(1) "I+ tC XI +.r r]d ' See Hoekman and Kostecki (2001) for a review of the WTO Agreement on Agriculture. 8 See de Gorter (2002) for a careful discussion of problems associated with measurement of the AMS. 9 In practice there may be heterogeneity even at the 6-digit level in that imports (or exports) may be of a higher quality than exports (imports). In some developing countries high quality imports may have only a limited degree of competition with low quality domestic production. If so, this will imply that traditional measures of protection such as the ratio of import to domestic price for the product will overstate the magnitude of protection. In this paper we use only tariffs, not the nominal rate-of protection. 'O The setup is very similar to the one in Zietz and Valdes (1986) and Hoekman, Ng and Olarreaga (2002). The latter discuss some of the caveats associated with the use of this type of model. Note that no account is taken of issues such as the potential .impact of exchange rate overvaluation, indirect taxes and other factors that may result in an overall anti-agriculture bias and thus offset the effect of tariff protection and/or subsidy policies. Schiff and Valdes (1998) suggest that in many developing countries anti-agriculture bias due to such policies has declined, implying that direct instruments such as tariffs and subsidies are the major determinants of the magnitude of protection. 5 where 8 d is the import demand elasticity, pw is the price in the "world" market; t, is the tariff in country c; cc is the average transport cost from country c to the "world" market;"I SC is the producer support in country c;12 Ad is the elasticity of import demand to the producer support; and ac is a demand parameter in country c that captures size and all other factors influencing import demand. Export supply for each HS-6-digit product of country c is given by: F 16 Xc = bc P(l + ) S (2) where 8s is the export supply elasticity, 2A is the elasticity of export supply with respect to domestic support;'3 and bc is a supply parameter that captures size and other determinants of export supply. The transport cost to world markets is also common among exporters and importers of the same product. The presence of tariffs and domestic support measures may lead to both imports and exports of a homogenous product for a given country. We are forced by data constraints to assume that the import demand and export supply elasticities for products, as well as the import and export elasticities with respect to domestic support, are identical for all countries in the sample. This has implications for the implied domestic supply and demand elasticities of domestic support across the countries in our dataset. For example, if these were relatively similar across countries, and consumption were to be only marginally affected by changes in domestic support, then import demand elasticities should vary across countries depending on the ratio of domestic production to exports. Given that production and consumption data are not available at the six-digit level of the Harmonized System, we cannot estimate underlying domestic demand and supply elasticities. In the empirical analysis below we test to what extent the assumption of identical elasticities across countries has implications for our results. This explains differences in import prices across different countries as observed in the data. 12 We attribute to countries with no domestic support a $1 value for the import demand function not to be undetermined. 13 Again, we attribute to countries with no domestic support a $1 dollar value for the export supply function not to be undetermined. The same caveat as in the previous footnote applies. 6 The equilibrium world price is obtained by solving for the world price in the world market clearing condition, i.e., l/(g.v+ed) '7 ~~ac ew = argslE tc XI +VA = =,3 PW ;0 -xc =01= o [( +ti S~] (3) Pw C C ,E bS Pw c c ~ ~ bcsc c (I+vrc) The change in the world equilibrium price following a reduction in tariffs is obtained by taking the total differential of (3) with respect to rc .

Note that if there is no producer support or tariffs in country c, then there will be no changes in export revenue or import revenue in this country, a part from those induced by the change in world price after other countries have reduced their tariffs or producer support. Finally, one can measure the change in welfare in an importing and exporting country by taking the integral of the import demand and export supply functions with respect to world prices and tariffs (it is assumed that domestic support is just a transfer from government revenue to producers). The change in exporters and importers welfare relative to their initial export and import revenue is then given by: C A+,( + Pw 1+ s ) c ~ d' Ad + (7) s tc t S tCr +t C where wvx is the change in welfare in an exporting country relative to the initial export revenue;15 wCv is the change in welfare in an importing country relative to the initial import revenue. The first term on the right-hand-side of i47' is the change in import consumer surplus and the second term is the change in tariff revenue. Note that changes in welfare in (7) take into account shifts of domestic import demand and export supply functions following changes in domestic tariffs and domestic support (when relevant). The overall change in welfare can be obtained by adding up '5 Note that is exactly equal to the percentage change in world prices if the elasticity of export supply is nil. 8 the two expressions in (7) after normalizing the two terms to the same base (either exports, imports, total trade, or in $ per capita terms). 4 Empirical methodology The empirical methodology consists of three steps. First we estimate import demand and export supply elasticities with respect to prices and subsidies (i.e., gd 6s Ad and As). We then calibrate the demand and supply parameters (i.e., a, and b, ) for each country and product (at the HS six-digit level). Finally, we use the elasticities and calibratecl parameters to measure the changes in world prices, export revenue, import revenue and welfare following a 50 percent reduction in agriculture tariffs and domestic support in all countries. To estimate the different elasticities, we could simply estimate the import demand and export supply functions (1) and (2). However, these are simultaneously determined in any country c. Moreover, we do not observe "world" prices, but only export and import unit values in each country, which include transport costs. If traded quantities are measured with error (which is likely as customs generally are more concerned with value), unit values will also be measured with error, which may bias our results.'6 To avoid these problems we first choose units so that the average world price of each product for the period 1995-199 8 is equal to 1. We then estimate, across countries and products, the net import demand function as the log difference of import demand and export supply for each country (measured in value terms due to the choice of units) in each country. Note that the world prices will then drop from this specification as log(p,) = log(1) = 0. Using the import demand and export supply functions in equations (1) and (2), we obtain the following estimating equation: log(mr )_ log(x' )= log(aj )- log(b, ) _d log(1 + t- )- (ed _ Es )log(l + r- - (d + X )log(s, ( 16 Note that it is not clear what can be use as an instrument for unit values at the six digit level of the harmonized system. 9 As controls for ac and bC we use GDP and population in each country. Product dummies at the HS six-digit level are also included.17 In the second step, using the elasticities estimated using a stochastic version of (8), we calibrate ac and bc using (1) and (2). The estimation of changes in world prices, import revenue, export revenue and welfare is done using equations (4) to (7). Data on import and export revenue as well as tariffs are available from the World Bank WITS database at the six digit of the harmonized system. The measure of domestic support that is used is the WTO Aggregate Measure of Support (AMS), obtained from the WTO, based on member notifications (WTO document G/AG/NGIS/1, April 13, 2000). The AMS data are based on an arbitrary product classification and were concorded to the HS classification (see the Data Annex). Only 30 WTO members have made domestic support reduction commitments under the Agreement on Agriculture (AoA), but all members are required to notify domestic support. Compliance is weak-in 1995 only 75 percent of all WTO members that were required to notify, did so. In 1996 and 1997 the coverage drops to around 50 percent; for 1998 only 28 percent of WTO members had notified by March 2000. However, most countries that did not notify in 1997-8 had very little or no support in 1995-6, so the coverage of the data spans the major users. To address the incomplete reporting problem, we use the average AMS reported for whatever years are available. The empirical analysis therefore involves an unbalanced panel. Domestic support notified to the WTO includes exempt and non-exempt measures. There are nine categories of support, designated DS 1 through DS9. DS 1 covers measures that WTO members have placed in the "green box", and are therefore exempt from reductions (the green box categories are defined in Annex 2 of the AoA). DS2 comprises measures that, for developing countries, are exempt from reduction commitments under Article 6.2 of the AoA relating to development programs. DS3 is used to signify direct payments under production-limiting programs under Article 6.5 of the AoA. Categories DS4 to DS9 comprise measures that are not necessarily exempt from reduction commitments. DS4 refers to non-exempt support that is below the de minimis level (as set out in Article 6.4 of the AoA). The remaining categories included in the total AMS of WTO members include market price support (DS5), non-exempt '1 A justification for the introduction of GDP and population as control variables could be associated with the idea that import demand for agriculture products is a function of the level of development in each country. Alternatively, the constrained version of (8) using GDP per capita could be interpreted as capturing the capital labor ratio of each country. The constrained specification yields results within one standard deviation of those reported later in Table 6. 10 direct payments (DS6), other product-specific support (DS7), and any support measured via the Equivalent Measurement of Support methodology (DS8). Finally, where relevant, a total figure for non-product-specific support is also given (DS9).18 Two problems with the estimation of equation (8) are (i) that transport costs are not directly observable and (ii) that we cannot retrieve the elasticity of import demand and export supply with respect to domestic support, but only its sum. Assumrting that transport costs to the world market are equal for exporters and importers, these costs can be proxied by the ratio of export and import unit values. As long as the measurement error in unit prices is identical for exports and imports the problems described above are addressed. As regards the second issue, we assume that elasticities of import demand and export supply with respect to domestic support are equal. 19 5 Results We first focus on the estimation of the price and domestic support elasticity of export supply and import demand and then turn into the results of the simulation exercise. Estimating elasticities Table 6 reports the results of the estimation of equation (8) using different measures of domestic support. In column 1 results are reported using notifications by WTO members of non-exempt support (this corresponds to categories DS4 to DS9 according to WTO notification procedures). These are (generally) product specific and include market price support (calculated according to the methodology in Annex 3 of the Uruguay Round Agreement on Agriculture) and non-exempt direct payments (denoted sf549). Column 2 reports results using: notifications on exempt domestic support (this corresponds to categories DS 1 to DS3 according to WTO notification procedures). These are non-product specific and include measures which WTO) members have placed in the "green box", measures that are exempt in developing countries and direct payments 'a CGE analyses are usually based on the PSE data compiled by the OECD, which not only includes price support measures, but, more importantly, does not correspond to the typology of measures that are the focus of WTO negotiations (e.g., production vs. other (decoupled) support. See Dimaranan (2002) for a noteworthy attempt to map PSE support data into types of policy measures as a function of the factor of production that is supported. 19 Note that if the ratio of production to exports and imports is different, then one should expect different elasticities of import demand and export supply for a given elasticity of dornestic supply to domestic support. One way to (partially) reconcile this with our results is to recognize that the change in domestic support will also affect domestic demand through changes in domestic and world prices. In the estimations, we test the robustness of our results by varying the elasticities with respect to domestic support on the demand and supply side. 11 under production-limiting programs (the 'blue box'). Such non-product specific support is allocated for purposes of estimation across products using the distribution of domestic support commitments by product (the idea being that exempt support is likely to be higher in sectors where non-exempt support is larger following a political-economy logic). This type of domestic support is denoted as 5DS13. Column 3 reports results of the estimation of (8) with the two types of domestic support entering separately. Finally, Column 4 reports results using the sum of both types of support. Given the unbalanced nature of the data set, we work with a between estimator, using as observations the average across the four year period for which support data are available, rather than the annual data (i.e., the sample is a cross-section of countries and products).20 The elasticities are then identified using the cross-country variation for each product.21 Results across the four specifications generally yield an elasticity of import demand around 1.36-1.45 and an elasticity of export supply around 0. 19-0.28. The (sum) of the elasticities of domestic support varies from almost 0 (in the case of DS 1-3 in column 3) to 0.10 in column 1 (for DS4-9). The fact that DS 1-3 is insignificant in column 3 may be due to collinearity problems given the methodology used to construct this variable (i.e., general domestic support is distributed across products using product specific support commitments). When both types of domestic support are added up in column 4, the (sum) of the elasticity of domestic support is statistically significant. To determine whether we should work with the sum of the two types of domestic support, we run a non-linear specification of equation (8) to test whether the two types of domestic support can simply be added up. Results are reported below, with standard errors in parenthesis:22 log(mr)-log(xr)= 0.29+ 0.34 log(gdp,)- 0.45 log(popJ)- 0.34 log(1+t )- (0.42) (0.04)** (0.04)** (0.05)** (9) 1.17 log(l +ħr- 0.04 log s DS4-9 + 0.00 s DSI-3 (0.08)** (0.02)* (0.00) c 20 This is also due to the fact that ad-valorem equivalents of specific tariffs have only been estimated for 1999 in OECD (2000) and Stawowy (2001). 21 Thus, the variation in import and export prices across countries, which is explained by transport cost to the "world" market, allows us to identify the different elasticities. 22 A "*" indicates statistical significance at the 5 percent level; "**" indicates significance at the I percent level. 12 Equation (9) suggests that we should drop the general domestic support DS 1-3 from the estimation, as the coefficient on sDSI3 is not significantly different from zero. In the specification we employ in the simulations below we therefore only include non-exempt domestic support s4-9, i.e., we use the results reported in column 1 of Table 6. Thus, the 50 percent reduction in domestic support used in the simulations pertains only to non-exempt domestic support (as exempt domestic support does not seem to affect trade flows and therefore should have no-or little-impact on world prices).23 The estimation in column 1 is done across the 158 HS 6 digit commodities. We assume these elasticities to be common across these different products. This is not necessarily the case of course, as there may be heterogeneity across products. Table 7 reports results of the estimation in column 1 of Table 6 letting the elasticity vary across different groups of products (a seemingly unrelated regression technique was used to provide standard error estimates to control for a common explanatory variable that is omitted from the regression). The first five! columns in Table 7 report the results for animal products (HS 01 to 04), vegetables, fruits and nuts (HS 6 to 9), cereals and grains (HS 10 to HS 14), processed food products (HS 15 to HS 24), and cotton and other textile fibers (HS 50 to 53). While the variations in import demand and export supply elasticities are quite large, the elasticity with respect to domestic support is similar across sectors (it varies between -0.07 and -0.16). The product group-specific elasticities are used below as the base estimates for the simulation exercises. The overall. estimates in column 1 of Table 6 are used to test for the robustness of the results.24 As mentioned, because we use the information on cross-country variation to estimate the different elasticities, it is assumed that these elasticities do not vary across countries. If we were to relax this constraint, the solution to the model in Section 3 would be non-linear. To determine the restrictiveness of this assumption we estimated the equation in column 1 of Table 6 for the developing countries only. All elasticities are within one standard deviation of the elasticities for the whole sample (except for the import demand elasticity which is within two standard deviations). We then estimated it for the three major users of domestic support separately: the 23 Note that exempt domestic support is generally de-linked from production and is more likely to affect the production decision rather than the level of production as measured when working with trade flows. 4 Note that for Animal products, Cereals and other grains, and Sillk, Cotton & other fibres, the coefficient capturing the import demand elasticity is insignificant whereas the difference between the import demand and export supply* price elasticities is significant. In these three cases, we cannot reject the assumption that the export supply elasticity is zero. We therefore set the export supply elasticities to zero in the simulations for these products and calibrate the import demand elasticities accordingly. 13 EU, Japan and the United States. The results suggest heterogeneity in the price elasticities across countries, but the imprecision in the parameter estimates did not allow the hypothesis to be rejected that they are equal across countries. Estimates of elasticities with respect to domestic support were relatively homogenous (-0.08 for the EU, -0.12 for Japan and -0.10 for the United States). Thus, the elasticity of net import demand with respect to domestic support seems to be relatively small (around 0.1) suggesting a reduction in domestic support across WTO members is likely to have a small impact on world prices.25 Simulation results In our baseline simulations we use the estimated coefficients in Table 7 to calibrate import demand and export supply in each country. Then changes in export revenue, import revenue, and welfare following a 50 percent cut in tariffs and domestic support to farmers across all WTO members are calculated for each country using (6) and (7). We also calculate the change in terms of trade by weighting the changes in prices by export and import shares in each country. Recall that the simulations are done for the 158 tariff lines at the HS 6-digit level for which at least one country provides domestic support to its farmers. (The overall agricultural universe includes more than 900 tariff lines at the HS 6-digit level). Table 8 reports results on the change in export revenue, the import bill, the terms-of-trade and welfare for the three broad country groups of a 50 percent tariff reduction or a 50 percent domestic support reduction. Aggregate product specific and individual country results are reported in Appendix Tables 1 and 2. The increase in trade across all country groups is much larger for the 50 percent tariff cut than for the reduction in domestic support. Exports of developing countries (excluding LDCs) increase by $4.2 billion, or 6.7 percent of the initial export revenue for the 158 product categories (Table 8). LDC exports increase by $116 million (or 3.7 percent), while industrialized country exports increase by $3.3 billion dollars (4.7 percent). There is also an increase in the import bill following the 50 percent tariff reduction. In industrial countries the increase in imports is double the increase in exports (due both to an 25 Note that the implicit assumption here is that domestic support only affects the variable cost of farmers receiving the subsidy, as we move along the export supply and import demand functions. If domestic support affects fixed costs (or the production decision), as is probably the case with subsidies that are decoupled from production, we would need to work along the domestic supply function. Data on production is not available for such a large number of countries at the disaggregated level required. This also suggests that we should be working only with non-exempt subsidies (which are generally not decoupled from production). 14 expansion in demand and higher world prices). The increase in imports in developing and least developed countries is roughly equal to the increase in exports.26 In relative terms many developing countries see a significant expansion in exports following a 50 percent cut in tariffs. Figure 1 plots the impact on exports of a 50 percent cut in tariffs (in the vertical axis) and domestic support (in the horizontal axis) trade for the 121 developing and least developed countries in the sample. The vertical and horizontal lines indicate a "zero" change in exports due to a cut in tariffs or domestic support, respectively. The highest percentage increases in exports are found in the Caribbean and Central American region reflecting the specialization of these countries in commodities such as edible fruits and vegetables, processed foods and sugar-the categories that see the largest expansion in demand in percentage terms (Appendix Table 1).27 Mauritius, Philippines and Thailand-all developing countries that are producers of such commodities--also see increases in exports of over 10 percent. With a few exceptions such as Congo and Malawi, Afirican countries tend to register only limited increases in exports. The increase in exports following a 50 percent cut in domestic support is a tenth of what is generated by cutting tariffs (Table 8). Developing country exports increase by $0.5 billion, or 0.8 percent of the 1995-1998 average level of exports. LDC exports rise by $64 million (2 percent), while industrial countries expand exports by $314 million (0.5 percent). More striking is the fact that the import bill decreases in developing and least developed countries after a 50 percent cut in domestic support (Figure 2). The reason for this is that world prices increase after the cut-import demand functions being relatively elastic, the import bill necessarily decreases. Welfare increases in all groups of countries after multilateral tariff rei.orrns (Table 8). The increase in welfare for developing countries generated by the 50 percent tariff cut is due not only to increased exports, but to the liberalization that occurs in these countries (and the absence of domestic support). In contrast, developing countries as a group would see a small reduction in welfare following a cut in domestic support. The relatively high tariffs that prevail in many of these countries explain why the impact in welfare terms is so different. The potential negative implication of a cut in domestic support illustrates the importance of also cutting tariffs. 26 Note that the increase in exports is not necessarily equal to the increase in imports at the aggregate level for two reasons. First, increases in export and import revenue are measured at customs and therefore include transport cost. Second, we did not have data for all countries, so it is assumed that the rest-of-the world also adjusts to changes in world prices. 15 In the case of LDCs the ratio of gains is quite different. Instead of a ten to one ratio of export gains due to tariff vs. domestic support cuts, it is only two to one. Moreover, the simulations suggest that LDCs will obtain welfare gains from both types of reform. These differences between the two country groups reflects both the LDCs greater 'sensitivity' in relative terms to OECD support policies and the pattern of production and trade in the various products. There is substantial heterogeneity across countries, reflecting differences in export and import bundles. Variations in the levels of tariffs and domestic support across different products in large trading partners also partly explain this heterogeneity. A cut of 50 percent in tariffs generates a relatively large increase in developing country exports of edible vegetables, fruits and nuts (HS07-08), sugar (HS 17) preparations of vegetables and fruits (HS 20-21) and tobacco (HS24). In the case of LDCs, the largest increases occur in meat (HS02), sugar and miscellaneous edible preparations (HS2 1) (Appendix Table 1).28 A large number of countries in the sample see their terrns-of-trade deteriorate after a 50 percent tariff cut (Appendix Table 2). This is also the case following a 50 percent cut in domestic support. Figure 3 plots the change in terms of trade following changes in tariffs and domestic support. As before, the vertical and horizontal lines indicate a "zero" change in the terms of trade. Changes in terms of trade seem to be positively correlated across the two types of cuts, i.e., countries that see their terms of trade increase after a tariff cut will also see their terms of trade improve after a domestic support cut. The fact that the terms-of-trade deteriorates does not necessarily imply a reduction in welfare, given that countries own reforms will tend to increase welfare. Nonetheless in a number of instances welfare does decline. This is the case in particular for oil producers and large net importers such as Algeria, Bahrain, Brunei, Egypt, Gabon, Oman, Russia, Saudi Arabia, and Venezuela. Any welfare losses are generally much smaller if the experiment is a 50 percent cut in domestic support. Figure 4 plots the change in welfare per capita under the tariff cut against the change in welfare per capita under the domestic support cut for the countries in the sample, with the horizontal and vertical lines again indicating a "zero" change in welfare. Thus, countries in the North East quadrant of Figure 2 see their welfare increase under both types of reforms. 27 To the extent that these countries enjoy tariff preferences in some products for these products, results may overstate their gains. But again, preferential access on paper does not necessarily mean actual preferences granted. Second, these are very small countries that only marginal affect the overall picture for developing countries. 28 Note that here we abstract from sanitary or phyto-sanitary barriers, as well as other non-tariff barriers that may also be hindering trade. 16 This includes Mauritius, Fiji, Belize, Guyana, Costa Rica, Uruguay, etc. There are no countries in the South East quadrant, suggesting that there is no case where a country increases its welfare following a cut in domestic support but sees its welfare reduced under the tariff cut. Losers under both types of reforms include the large net importers mentioned previously. Sensitivity analysis Given the various assumptions made with respect to elasticities, a number of sensitivity analyses were performed. We first re-estimated the figures in Table 8 using the elasticity estimates provided for the whole sample in the first column of Table 6 (finstead of the elasticity estimates by product reported in Table 7). We also re-estimated the numbers of Table 8 using extreme values (i.e., instead of half the estimated coefficient in Table 8, we use either zero or the total value of the estimated coefficient) for the elasticities of domestic support on the import and export side. Finally, we compared results with the case where only OECD members reduce their tariffs and domestic support. Using the elasticities estimated for the whole sample, the increase in exports after a 50 percent tariff cut is 25 percent lower for developing countries and 15 percent lower for LDCs. On the other hand, the increase in exports after a 50 percent cut in domestic support is 25 percent higher for developing countries, but 20 percent lower in the case of LDCs. T hus the imbalance in terms of gains is partly reversed. However, the qualitative results remain: the increase in exports by developing countries is 5 times larger under the 50 percent tariff cut than under the 50 percent domestic support cut. Similarly, for LDCs the increase in exports under the 50 percent tariff cut is 2 times larger than under the domestic support cut. The welfare gains for developing countries are positive in the case of tariffs, whereas they suffer welfare losses when domestic support is cut. For LDCs the welfare increase is 50 percent higher under the tariff cut. As noted earlier, we cannot empirically identify the elasticity of domestic support on import demand and export supply separately, but only its sum. To test the sensitivity of our assumption that the two are equal, we assume that each in turn is zero and that the coefficient identifies the other one. The estimated changes in export revenue, imports and welfare of a 50 percent tariff cut are not affected by these modifications (as import demand and export supply are re-calibrated accordingly). In the case of a 50 percent cut in domestic support, the increase in exports by developing countries is 30 percent higher when we assume that the domestic support elasticity of export supply is zero and 80 percent lower when we assume that the domestic 17 support elasticity of import demand is zero. In terms of developing countries' welfare, the loss is 22 percent lower when the elasticity of export supply is zero and 25 percent higher when the elasticity of import demand is zero. However, the qualitative results remain the same. In the case of LDCs, the estimated change in exports is only marginally affected under both scenarios. We also ran a scenario where the 50 percent cut in tariffs and domestic support is undertaken only by OECD countries. In the case of domestic support, the increase in exports of developing countries is only 3 percent lower, which suggests that for non-LDC developing countries almost all the action from the reduction in domestic support comes from actions by the OECD. However, the increase in exports is 25 percent lower for LDCs. This suggests that domestic support in other developing countries affect LDC exports to a larger extent than other developing countries. This is also the case for tariff cuts. When OECD countries cut their tariffs by 50 percent, the increase in LDC exports is only 30 percent of the increase in exports when all WTO members reduce their tariffs by 50 percent. For other developing countries, the increase in exports under an OECD tariff cut is only half of the $4.2 billion generated if all WTO members reduce their tariffs by 50 percent. These results illustrate the importance of more general liberalization of trade in the commodities concerned. 6 Conclusions As is the case for tariff peaks-see Hoekman, Ng and Olarreaga (2002)-we find that LDCs are disproportionately affected by agricultural support policies. Reducing such support is therefore important. However, tariffs matter a lot more than subsidies in terms of their impact on world prices. The positive welfare effect of reducing tariffs onproducts that are also affected by agricultural support is a multiple of what can be achieved from an equivalent percentage cut in domestic support only-tariff reductions generate welfare gains that are a multiple of what can be obtained from reductions in support policies. This not only reflects the high tariff peaks in OECD countries, but the fact that developing countries use tariffs to protect domestic production. These countries generally have low levels of domestic support, reflecting both budget constraints and a more neutral policy stance in terms of supporting this sector of the economy. Our analysis suggests the primary focus of attention should therefore be on reducing border protection in both OECD and developing countries. The negotiating challenge is how to achieve this. For developing countries tariffs are an important-indeed often the only- instrument of intervention that they have available to respond to the effects of OECD subsidy 18 policies. An important dimension of agricultural support policies that has been ignored in this paper-the impact on price volatility-plays a major role here (Valdes and Foster, 2002). Tariff protection can shelter farmers from import surges in periods where world prices drop significantly. Whatever the source of the exogenous shock that drives prices down, much of the adjustment may fall disproportionately on residual (non-OECD) markets because support policies shelter OECD farmers from the shock. Unilateral liberalization of agricultural trade in countries such as India proved to be politically umsustainable as farmers were subjected to large world price swings and import surges of subsidized commodities (Gulati and Narayanan, 2002). Further agricultural trade liberalization in developing countries may be significantly impeded in an environment that is characterized by continued large-scale support for OECD farmers. Substantial reduction in OECD agricultural support policies is therefore important not only because it generates direct benefits for the many developing economies that are net exporters, it is critical to create the political support to induce (allow) developing country governments to continue to pursue welfare improving domestic agricultural trade policy reforms. Thus, reductions in production subsidies in OECD cotntries are necessary, although not sufficient, for developing countries to reap significant gains from the current WTO negotiations on agriculture. At the same time, as noted by Anderson (2002), if OECD members were to move on the subsidy front, it is important that developing countries reduce protection. Without own liberalization the negative welfare effects for countries that experience terms of trade losses would likely be greater. The fact that our simulations suggest that a number of countries are predicted to lose from reforms suggests liberalization and removal of domestic support should be accompanied by compensation mechanisms, which could include additional 'aid for trade' (Hoekman, 2002). Any negotiated reforms will only be implemented gradually, allowing for measures to support adjustment. Such measures should include actions that improve the functioning of input, downstream and factor markets to support efforts by farmers to expand output in response to a rise in prices (Anderson and Hoekman, 2000). Measures to ieduce costs for farmers are particularly important. Examples include action to improve the efficiency of services-finance, insurance, transport, storage, packaging, etc. The cost-increasing effect of inefficient services can be substantial-as illustrated in recent research on transport services (Fink et al. 2002; Francois and Wooton, 2001). Indeed, if such accompanying measures are taken, the resulting supply 19 response may cause some countries to shift from net importer to net exporter status, attenuating the magnitude of the negative effects estimated above (Anderson, 2002). Finally, it is important to bear in mind that our analysis has been limited to only a few- the subsidized-commodities. The Doha negotiations span all trade, including non-subsidized agricultural products and manufactures. The overall welfare numbers generated by our analysis are therefore not particularly relevant, except to indicate that the countries that lose from reforms that affect the subsidized subr set of agricultural products will need to identify other areas in which they can generate offsetting gains. In principle this should be feasible given the large negotiation set that was established in Doha. 20 References Anderson, Kym. 2002.

When countries did not report trade data to Comtrade we mirror their data using notifications by their trading partners. Tariffs are drawn from the UNCTAD and WTO as provided in UNCTAD/World Bank World Integrated Trade Solution (WITS) system. This database does not include the ad-valorem equivalent of specific tariffs. For ad-valorem equivalents of specific tariffs we rely on Stawowy (2001) for estimates for Canada, the European Union, Japan and the United States and OECD (2000) for other OECD countries. In cases where tariff quotas are used, tariff rates generally comprise the average of in and out of quota tariffs is generally taken, although in some cases only the out of quota tariff is available. The OECD ad-valorem equivalents of specific tariffs use exclusively out of quota tariffs. We do not have quota information, this may bias results some estimates as some import prices may be higher if exporters benefit from in-quota lower tariffs. As mentioned in the text, the source of domestic support data is the WTO (document G/AG/NG/S/1). This data comes in national currency and was transformed into US dollars using the period average exchange rate reported in the IMF IFS. The product classification in each country notification is arbitrary and therefore we filter the product classification into the Harmonized System 6 digit classification. In most cases this can be done through a one-to-one mapping. In some cases, the domestic support reported covers several 6 digit tariff lines, in which case the subsidy was distributed across the relevant tariff lines using the share of the reporting country's exports as weights. The concordance file is available from the authors on request. As exempt subsidies are not product specific, these were also mapped into a product specific subsidies using as weights the product-specific commitments that each country made in the Uruguay Round. Non-product specific support is divided evenly into all products exported by the country concerned. All products shown in notifications to the WTO are included, whether or not the support is below the de minimis level for the member concerned. Thus, total AMS may exceed total WTO commitments for a country.
