POVERTY DYNAMICS DURING TRADE REFORM: EVIDENCE FROM RURAL VIETNAM

This paper implements and adapts the conceptual framework developed by Winters (2002) that identifies the transmission mechanisms between trade policy reform and household welfare outcomes. We make use of household panel data from Vietnam collected in two years, 1992–93 and 1997–98 that span the very earliest years of the reform period and its immediate after effects. Poverty dynamics are modeled using changes in consumption expenditure and poverty transition models. The trade effect is captured by a set of variables that are most likely to have an impact on rural poverty, namely prices of staples and employment in the export sector. We show that trade liberalization has a material and positive effect on rural household welfare and this trade effect is largely transmitted to the poor through the labor market channel.     

Openness and Poverty in the Postwar United States

Recent trade theory suggests that freer trade can be the primary cause of the observed rise of poverty in the United States. The short-run dynamic relationships between openness and poverty are examined using the concept of Granger causality. That the ultimate source of rising poverty since 1973 is trade liberalization of the US economy cannot be rejected. The result is convincing when two subsamples (pre- and post-1973) are reestimated. These findings are at odds with the conventional model in which freer trade raises productivity and hence reduces the poverty rate, but appear consistent with some models in which openness raises poverty.     

The impact of China's accession to the WTO on its economy: an imperfect competitive CGE analysis

To examine the impact of trade barrier reductions on the Chinese economy following its WTO accession, a single‐country, static CGE (Computable General Equilibrium) model is constructed, which incorporates certain elements of imperfect competition in China's current economic situation. China's real GDP and total employment are expected to rise by small degrees, while the general price level may decline by a few percentage points. Total imports would rise by more than 10%, whereas total exports would increase far less. China's trade surplus is, therefore, likely to shrink substantially and its dependence upon foreign trade is likely to rise by a few percentage points. A sensitivity analysis confirms the robustness of the simulation results. A comparison with other CGE studies on China's trade liberalization also shows the plausibility of this study's predictions.

The transition to a globalized economy: Poverty,human capital and the informal sector in a structuralist CGE model

Recent econometric evidence suggests that trade liberalization has an elusive relationship to growth and income distribution. This paper provides an explanation for these results via numerical simulations of a dynamic structuralist CGE. The conclusion is that if families become too poor to finance human capital accumulation, or the state too stingy to supply it at a reasonable cost, exports of skill-intensive goods can become uncompetitive and the transition to openness may involve increasing poverty, unemployment and stagnation. The model design incorporates an informal sector as well as accumulation of human capital. The paper simulates two trajectories, a “green” path in which per capita income grows steadily with a rapid rate of human capital accumulation and a reduction in the level of economic informality. A second, or “red” path is also possible, however, with a growth rate that is much lower, an expanding informal sector and an inadequate rate of human capital formation.     

贸易自由化影响农村贫困的路径与特征

城乡人口流动是当今社会最重要的经济现象,贸易自由化的影响最为显著,为此,我们运用门槛面板数据模型实证研究了贸易自由化影响我国农村贫困的路径和特征。结果发现,贸易自由化主要从经济增长、就业与工资以及物价水平路径影响农村贫困。并且,贸易自由化和农村贫困之间存在一种非线性的倒U关系,即在贸易自由化初期,贸易自由化加重了农村贫困,当贸易自由化水平越过某一门槛值时,贸易自由化有助于农村减贫。因此,继续扩大自由贸易的层次与规模,是未来农村反贫困的一个政策选项。     

Economic and environmental impacts of trade liberalization: The case of Indonesia

In recent years, there has been a growing interest in the environmental impacts of trade liberalization. This paper provides further discourse in this area with a study on Indonesia and its trade agreements with Japan (IJEPA) and ASEAN (AFTA). A static global CGE model, known as the Global Trade Analysis Project, was used to project the Indonesian economy to the year 2022, with and without tariff reforms agreed under the agreements. Environmental impacts are assessed using different pollution indicators—air, water and waste. The study suggests that Indonesia would grow rapidly over the period considered with a large deterioration in its environment. Following these, however, the agreements only have a marginal positive impact on Indonesia's output but with a noticeable increase in trade flows and signs of trade diversion. Overall AFTA has a greater impact on the Indonesian economy compared to IJEPA. Similarly, the impact of trade liberalization on the environment is marginal. On the whole, tariff reform is inducing air pollution and reducing water pollution. In conclusion, the study suggests that Indonesia's participation in the AFTA and IJEPA agreements is not likely to bring drastic changes to her economic and environmental performance.     

Transport Modal Choice by Multinational Firms: Firm-level Evidence from Southeast Asia

The impacts of trade liberalization on poverty status of farm households in Africa often come through its effects on prices, government revenues, and employment, among other things. For the case of Ethiopia, the main channel through which trade liberalization affects farm households is changes in the prices of inputs and outputs. The aim of this study is to empirically examine the impacts of trade reform on poverty status in rural Ethiopia. The results show that, although households’ resource endowment had consistent and significant improvement impacts, trade liberalization had mixed effects on change in poverty status. As a result of trade liberalization, contrary to expectation, changes in the prices of cash crops (i.e. chat and coffee) had increased the probability of remaining poor and falling into poverty. On the other hand, changes in the relative prices of staple food crops (i.e. teff and wheat), together with access to credit and schools, had increased the probability of escaping poverty and remaining above the poverty line.     

Analyzing the effects of the Regional Comprehensive Economic Partnership on FDI in a CGE framework with firm heterogeneity

The Regional Comprehensive Economic Partnership (RCEP) is a free trade agreement (FTA) that is currently under negotiation among China and 15 other Asian countries. It is one of several potential mega-regional FTAs in the Asia-Pacific region. In this paper we investigate the potential effect of RCEP on foreign direct investment (FDI) with a focus on China using an innovative computable general equilibrium (CGE) model. The model is built on the theory of firm heterogeneity extended to FDI. The framework is able to capture FDI increases along both the intensive and extensive margins. Liberalization under RCEP is simulated as impacting on FDI both directly through FDI liberalization and indirectly through trade liberalization. Our simulation results suggest that RCEP would encourage significant increases in FDI to China through both these pathways. While competition from imports drives out the least productive foreign owned firms, export expansion of firms using FDI will lead to an overall increase in foreign investment. In addition, the facilitation of trade in intermediate goods tends to promote vertical FDI. The direct FDI effect from investment liberalization will evidently promote FDI from partners. Projected economic gains to China from RCEP are in the range of US$103–214 billion, or 1.1–2.2% of GDP.     

Induced Institutional Change in the Trade and Environment Debate

Because of the assumption of constant emission factors, economy-environment models often show that free trade has negative environmental consequences. However, this pessimistic view ignores the possibility of trade strengthening the demand for regulatory institutions. An `institutional optimism hypothesis, stating that the net environmental result of trade liberalization is benign, is thus formulated in this paper. The hypothesis is examined with a CGE model that treats institutional change as an endogenous process dependent on income. Application to NAFTA, using a broad range of scenarios, provides some support for the institutional optimism hypothesis. The net pollution effect of trade liberalization is in many cases beneficial or low, even for the country specializing in polluting industries. The implication is that in many cases environmental interests are served better by a focus on institution building in trading partners, than on the process of trade liberalization itself.     

An Eaton–Kortum model of trade and growth

We combine a multi‐country, continuum‐good Ricardian model of Eaton and Kortum (2002) with a multi‐country AK model of Acemoglu and Ventura (2002) to examine how trade liberalization affects countries' growth rates and extensive margins of trade over time. Focusing on the three‐country case, we obtain three main results. First, a permanent fall in any trade cost raises the balanced growth rate. Second, trade liberalization increases the liberalizing countries' long‐run fractions of exported varieties to all destinations. Third, the long‐run effects of trade liberalization are different from its short‐run effects, which can reverse the welfare implications of the static Eaton–Kortum model.     

Quantifying the impacts of China’s currency depreciation and capital control: a CGE analysis

A dynamic global multi-regional computable general equilibrium (CGE) model is built to study the effects of Renminbi (RMB) depreciation and capital account liberalization. The simulation results suggest that although the depreciation of RMB can promote China’s trade surplus, it will nevertheless discourage domestic investment, consumption and lead to a decrease of real GDP.     

Testing Prediction Performance of Poverty Models: Empirical Evidence from Uganda

This paper examines the performance of a method of predicting poverty rates. Because most developing countries cannot justify the expense of frequent household budget surveys, additional low‐cost methods have been developed and used. The prediction method is based on a model linking the proportion of poor households to suitable explanatory variables (consumption proxies). These consumption proxies are variables that can be collected at much lower cost through smaller annual surveys. Several applications have shown that such models can produce poverty estimates with confidence intervals of a similar magnitude to the poverty estimates from the household budget surveys. There is, however, limited evidence of how well the methods perform out‐of‐sample. A series of seven household budget surveys conducted in Uganda in the period 1993–2005 allows us to test the prediction performance of the model. We test the poverty models by using data from one survey to predict the proportion of poor households in other surveys, and vice versa. The results are encouraging, as all models predict similar poverty trends. Although in most cases the predictions are precise, sometimes they differ significantly from the poverty level estimated from the survey directly.     

Reducing unwanted consequences of aggregation in large-scale economic models - A systematic empirical evaluation with the GTAP model

We discuss how to avoid aggregation bias in large-scale global Computable General Equilibrium (CGE) models by reducing the need of pre-model aggregation, based on the combination of algorithmic improvements and a filtering approach which removes small transactions. Using large-scale sensitivity analysis, we show the impact of pre-aggregation and filtering on model size, model solution time and simulated welfare impacts, using a multi-lateral partial trade liberalization simulated with the standard GTAP model as the test case. We conclude that pre-model aggregation should be avoided as far as possible, and that our filtering approach and algorithmic improvements allow global CGE analysis even with highly disaggregated data sets at moderate solution times.     

Quantifying the impact of services liberalization in a developing country

We compare goods versus services liberalization in terms of welfare, outputs, and factor prices in Tunisia using a CGE model with multiple products, services and trading partners. Restraints on services trade involve both cross-border supply (tariff-equivalent price wedges) and on foreign ownership (monopoly-rent distortions and inefficiency costs). Goods-trade liberalization yields a modest gain in aggregate welfare. Reducing service barriers generate relatively large welfare gains and low adjustment costs. Services liberalization increases economic activity in all sectors and raise the real returns to both capital and labor. The results point to the potential importance of deregulating services provision for economic development.     

The Division and Size of Gains from Liberalization in Service Networks*

If two disjoint country service networks involving a small and large country are connected as part of international liberalization in the presence of network externalities, the per capita gain for the small country from access to a large network will be large, and the per capita gain for the large country will be small. In contrast to goods, the benefits of liberalization in network‐related services are more likely to be approximately equally divided between large and small countries than is true of trade in goods, where benefits accrue disproportionately to the small country. We also argue that non‐cooperation in network‐related services trade may involve more extreme retaliation than suggested for trade in goods by the optimal tariff literature, so that relative to a non‐cooperative outcome, gains from liberalization in network‐related services become larger than from liberalization in goods. We develop simple models which we use for numerical examples showing these points, along with an empirical implementation for global telecoms liberalization for the US, Europe, Canada, and the rest of the world using the framework developed in the paper. This shows similar proportional gains to regions, consistent with the theme of the paper that goods and services liberalization differ.     

Trade Liberalization and the Profitability of Mergers: a Global Analysis*

We analyze the effects of bilateral tariff reductions on the profitability of cost‐reducing horizontal mergers. Given Cournot competition in a two‐country world, for any positive tariff below a certain threshold, marginal trade liberalization is shown to encourage only those domestic mergers with sufficiently large cost‐savings and to discourage the rest. For tariffs close to, but smaller than, the prohibitive tariff, however, marginal trade liberalization necessarily encourages all domestic mergers. Moreover, we show that for a given level of cost‐savings, the impact of marginal trade liberalization may not reliably predict that of nonmarginal liberalization. Although at high tariffs, domestic mergers are shown to be unambiguously more profitable than cross‐border mergers, near free trade, mergers which yield the most cost‐savings become the most profitable. Thus, when comparing domestic and cross‐border mergers, trade liberalization encourages the type which yields the most cost‐savings.     

How well do tree plantations comply with the twin targets of the Clean Development Mechanism? — The case of tree plantations in Tanzania

The Clean Development Mechanism (CDM) of the Kyoto Protocol is supposed to provide both carbon mitigation and poverty reduction. This article reports from a model based study of market related carbon leakage and poverty reduction in the wake of a CDM tree-planting project in Tanzania. A tree plantation was incorporated in a computable general equilibrium (CGE) model with income differentiated household segments. The study focused on sensitivity of carbon leakage and income distribution to different project ownerships and carbon premium allocations. It turned out that the project value in terms of carbon premium has clear shortcomings as indicator of induced GDP growth and poverty alleviation. The non-poor rural and urban households benefit considerably more than the poor households. However, rising household income in all domestic project ownership arrangements increases demand for food, raises use of fertilizer and crop yields. A carbon cycle module for agricultural land use was incorporated in the CGE model, showing an increased carbon sequestration in agricultural soil, representing a negative leakage through markets in the range of 60-120% of the certified emissions reductions as registered in the CDM tree plantation project.     

Intra‐industry Trade Liberalization: Why Skilled Workers are More Likely to Support Free Trade

This paper presents a theoretical model and empirical analysis that connects the prevalence of intra‐industry trade with increased wage inequality from trade liberalization in both skilled and unskilled labor abundant countries. The Stolper–Samuelson effect is incorporated into an intra‐industry trade liberalization (intra‐ITL) hypothesis where skilled labor opposes protectionism in all countries engaged in intra‐industry trade because skilled workers gain at the expense of unskilled workers from multilateral trade liberalization within the skill‐intensive sector. We examine empirical evidence on whether skilled individuals are more supportive of trade liberalization than unskilled individuals across 31 countries with different levels of intra‐industry trade and skill endowments. We find that the extent to which countries engage in intra‐industry trade in high‐tech commodities is strongly linked with the intensity of opposition to protection by skilled labor. Regression results strongly support our hypothesis that skilled workers, almost everywhere, are more likely to support free trade.     

Effects of a Free Trade Agreement on the Exchange Rate Pass‐through to Import Prices

This paper investigates the effect of trade liberalization on the exchange rate passthrough (ERPT) to import prices. To do so, it employs an empirical estimation of the effects of North American Free Trade Agreement (NAFTA) on the Mexican ERPT, and uses a Ricardian general equilibrium model. The model identifies two channels that explain how the trade liberalization alters the ERPT. The first channel is the direct relationship between the tariffs and the pass‐through by good. The second channel is the effect that tariffs have on the composition of imports, altering indirectly the aggregate pass‐through.
