Trade liberalization, poverty and efficient equity

Even if trade liberalization results in aggregate welfare gains over all households, it is possible that the poorest households could lose. We illustrate two approaches to designing trade liberalization in Turkey which ensure that the poor will not lose. The first approach uses direct compensation to losers. The second approach uses limited policy reform, where exceptions to the across-the-board reform are chosen to meet the equity goal. In each case, we map out some of the efficiency costs of attaining these equity goals so as to inform policy makers about the least costly way of attaining them.

Regional, multilateral, and unilateral trade policies on MERCOSUR for growth and poverty reduction in Brazil

The authors estimate that the Free Trade Agreement of the Americas (FTAA), the EU-MERCOSUR agreement, and multilateral trade policy changes will all be beneficial for Brazil. The Brazilian government strategy of simultaneously negotiating the FTAA and the EU-MERCOSUR agreement, while supporting multilateral liberalization through the Doha Agenda, will increase the benefits of each of these policies. The authors estimate that the poorest households typically gain roughly three to four times the average for Brazil from any of the policies considerethe United States protects its most highly protected markets. Both the FTAA and the EU-MERCOSUR agreements are net trade-creating for the countries involved, but excluded countries almost always lose from the agreements. The authors estimate that multilateral trade liberalization of 50 percent in tariffs and export subsidies results in gains to the world more than four times greater than either the FTAA or the EU-MERCOSUR agreement. This shows the continued importance to the world trading community of the multilateral negotiations.

The Impact on Russia of WTO Accession and the Doha Agenda: The Importance of Liberalization of Barriers Against Foreign Direct Investment in Services for Growth and Poverty Reduction

Taking price changes from the Global Trade Analysis Project (GTAP) model of world trade, the authors use a small open economy computable general equilibrium comparative static model of the Russian economy to assess the impact of global free trade and a successful completion of the Doha Agenda on the Russian economy, and especially on the poor. They compare those results with the impact of Russian accession to the World Trade Organization (WTO) on income distribution and the poor. The model incorporates all 55,000 households from the Russian Household Budget Survey asrealhouseholds. Crucially, given the importance of foreign direct investment (FDI) liberalization as part of Russian WTO accession, the authors also include FDI and Dixit-Stiglitz endogenous productivity effects from liberalization of import barriers against goods and FDI in services. The authors estimate that Russian WTO accession in the medium run will result in gains averaged over all Russian households equal to 7.3 percent of Russian consumption (with a standard deviation of 2.2 percent of consumption), with virtually all households gaining. They find that global free trade would result in a weighted average gain to households in Russia of 0.2 percent of consumption, with a standard deviation of 0.2 percent of consumption, while a successful completion of the Doha Development Agenda would result in a weighted average gain to households of -0.3 percent of consumption (with a standard deviation of 0.2 percent of consumption). Russia, as a net food importer, loses from subsidy elimination, and the gains to Russia from tariff cuts in other countries are too small to offset these losses. The results strongly support the view that Russias own liberalization is more important than improvements in market access as a result of reforms in tariffs or subsidies in the rest of the world. Foremost among the own reforms is liberalization of barriers against FDI in business services.

The Impact of Liberalizing Barriers to Foreign Direct Investment in Services: The Case of Russian Accession to the World Trade Organization

In this paper we employ a computable general equilibrium model of the Russian economy to assess the impact of accession to the World Trade Organization (WTO), which encompasses improved market access, tariff reduction and reduction of barriers against multinational service providers. We assume that foreign direct investment in business services is necessary for multinationals to compete well with Russian business service providers, but cross-border service provision is also present. The model incorporates productivity effects in both goods and services markets endogenously, through a Dixit-Stiglitz framework. The ad valorem equivalent of barriers to foreign direct investment have been estimated based on detailed questionnaires completed by specialized research institutes in Russia. We estimate that Russia will gain about 7.2 percent of the value of Russian consumption in the medium run from WTO accession and up to 24 percent in the long run. We estimate that the largest gains to Russia will derive from liberalization of barriers against multinational service providers. Piecemeal and systematic sensitivity analysis shows that our results are robust. Corresponding author: David Tarr MSN 3-303 The World Bank 1818 H.

Trade Liberalization and Endogenous Growth in a Small Open Economy: A Quantitative Assessment

The authors develop a numerical endogenous growth model approximating an infinite horizon, which allows them to investigate the relationship between trade liberalization and economic growth. Economic theory generally implies that trade liberalization will improve economic growth, and the two phenomena are positively correlated in empirical tests, but the connection is not well-substantiated in numerical general equilibrium models. In the authors model, an intermediate input affects aggregate output through a Dixit-Stiglitz function. Additional varieties provide the engine of growth in this framework and the existence of this mechanism magnifies the welfare costs. In this model with lump sum revenue replacement, reducing a tariff from 20 percent to 10 percent produces a welfare increase (in terms of Hicksian equivalent variation over the infinite horizon) of 10.7 percent of the present value of consumption in their central model, where the economy is assumed to be unable to borrow on international financial markets. If macroeconomic and financial reforms are in place that would allow international borrowing, however, the same tariff cut is estimated to result in a 37 percent increase in Hicksian equivalent variation. On the other hand, if inefficient replacement taxes must be used in an economy without the capacity to borrow internationally, the gains would be reduced to 4.7 percent. Larger tariff cuts--typical of those in many developing countries over the past 30 years--produce larger estimated welfare gains at least proportionate to the size of the cut. The authors apply the model to five developing countries and estimate the impact of the tariff changes those countries plan to undertake as part of Uruguay Round commitments. Because of the dynamic effects, estimated gains are considerably larger than those found in the literature on the impact of the Uruguay Round.

Chile's Regional Arrangements and the Free Trade Agreement of the Americas: The Importance of Market Access

Using a multisector, computable general equilibrium model, the authors examine Chiles strategy of negotiating bilateral free trade agreements with all of its significant trading partners (referring to this policy as additive regionalism). They also evaluate the Free Trade Agreement of the Americas (FTAA) and global free trade. Among Chiles bilateral regional agreements, only Chiles agreements withNorthernpartners provide enough market access to offset the costs to Chile of trade diversion. Because of preferential market access, however, additive regionalism is likely to provide Chile with many times as many gains as the static welfare gains from unilateral free trade. The authors find that at least one partner country loses from each of the regional trade agreements they consider, and excluded countries as a group they always lose. They estimate that the FTAA produces large welfare gains for the members, with the European Union being the big loser. Gains to the world from global free trade are estimated to be at least 36 times greater than gains from the FTAA. Even countries of the Americas in aggregate gain more from global free trade than from the FTAA.

Rules of Thumb for Evaluating Preferential Trading Arrangements: Evidence from Computable General Equilibrium Assessments

Most interesting results on the welfare effects of regional arrangements are ambiguous at a theoretical level. Many questions only have quantitative answers that are specific to the particular structural features of the economy and the policy considered. So, to determine the impact of prospective regional arrangements governments often rely on a quantitative evaluation. Usually at the request of client governments of the World Bank, the authors have implemented many computable general equilibrium (CGE) models to inform policymakers. The authors summarize the main conclusions drawn from these studies. The principal conclusions are: 1) Countries excluded from a preferential trade arrangement almost always lose. 2) Market access is a key determinant of the net benefits of a preferential trade arrangement. 3) With a free trade agreement (FTA) the external tariff can be lowered such that a poor FTA becomes attractive. 4) For Southern countries, North-South agreements offer a beneficial increase in competition in their home markets, and involve little increase in the supply price of Northern country sales in Southern countries. 5) Multilateral trade liberalization results in significantly larger gains to the world than the network of regional arrangements. 6) For individual countries without high protection,additive regionalismwill likely result in substantially larger gains than unilateral trade liberalization. 7) Tax replacement requirements reduce the set of desirable regional arrangements. 8) Trade taxes are often an inefficient source of tax revenue. 9) Trade liberalization should be expected to be pro-poor in developing countries, but results will be diverse at the household level so safety nets are important. 10) Dynamic effects to reverse conclusions regarding regionalism are not expected.

Regional impacts of Russia's accession to the World Trade Organization

In this paper we develop a computable general equilibrium model of the regions of Russia to assess the impact of accession to the World Trade Organization (WTO) on the regions of Russia. We estimate that the average gain in welfare as a percentage of consumption for the whole country is 7.8 percent (or 4.3 percent of consumption); we estimate that three regions will gain considerably more: Northwest (11.2 percent), St. Petersburg (10.6 percent) and Far East (9.7 percent). We estimate that the Urals will gain only 6.2 percent of consumption, considerably less than the national average. The principal explanation in our central analysis for the differences across regions is the ability of the different regions to benefit from a reduction in barriers against foreign direct investment. The three regions with the largest welfare gains are clearly the regions with the estimated largest shares of multinational investment. But the Urals has attracted relatively little FDI in the service sectors. An additional reason for differences across regions is quantified in our sensitivity analysis: regions may gain more from WTO accession if they can succeed in creating a good investment climate.

Telecommunications Reform within Russia's Accession to the World Trade Organization

In World Trade Organization (WTO) accession negotiations, telecommunications is always a sector that receives close scrutiny by the WTO Working Party, and the extent of market access and nondiscriminatory treatment of multinational telecommunications companies in Russia has been a significant issue in Russia’s accession negotiations. The authors use a computable general equilibrium model of the Russian economy to assess the role of telecommunications in the discussions regarding Russian accession to the WTO. The results show that reduction of barriers to foreign direct investment in telecommunications will bring substantial gains to the Russian economy, including an increase in the productivity of Russian labor and capital. Despite the fact that multinationals use Russian labor less intensively than Russian firms, demand for Russian labor employed in telecommunications should increase, following reductions in barriers to foreign direct investment that are included in the context of WTO accession. This is because the overall demand for telecommunication services should increase due to the growth effects of the liberalization of barriers against foreign direct investment generally and the reduction in tariffs. Russian capital owners in telecommunications will likely be sought as joint venture partners and can restructure and obtain gains as partners with foreign firms. Wholly owned Russian firms are likely to experience losses.

Regional household and poverty effects of Russia's accession to the world trade organization

This paper develops a seven-region comparative static computable general equilibrium model of Russia to assess the impact of accession to the World Trade Organization on these seven regions (the federal okrugs) of Russia. In order to assess poverty and distributional impacts, the model includes ten households in each of the seven federal okrugs, where household data are taken from the Household Budget Survey of Rosstat. The model allows for foreign direct investment in business services and endogenous productivity effects from additional varieties of business services and goods, which the analysis shows are crucial to the results. National welfare gains are about 4.5 percent of gross domestic product in the model, but in a constant returns to scale model they are only 0.1 percent. All deciles of the population in all seven federal okrugs can be expected to significantly gain from Russian World Trade Organization accession, but due to the capacity of their regions to attract foreign direct investment, households in the Northwest region gain the most, followed by households in the Far East and Volga regions. Households in Siberia and the Urals gain the least. Distribution impacts within regions are rather flat for the first nine deciles; but the richest decile of the population in the three regions that attract a lot of foreign investment gains significantly more than the other nine representative households in those regions.
