Modeling services liberalization: The case of Kenya

This paper employs a 55 sector small open economy computable general equilibrium model of the Kenyan economy to assess the impact of the liberalization of regulatory barriers against foreign and domestic business service providers in Kenya. The model incorporates foreign direct investment in business services and productivity effects in imperfectly competitive 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 specialists in Kenya. We estimate very substantial gains to Kenya from regulatory liberalization in business services, and additional gains from uniform tariffs. The estimated gains increase to 50% of consumption in the long run steady state model, where the impact on the accumulation of capital from an improvement in the productivity of capital is taken into account. Decomposition exercises reveal that the largest gains to Kenya will derive from liberalization of costly regulatory barriers that are non-discriminatory in their impacts between Kenyan and multinational service providers.     

Beyond the average effects: The distributional impacts of export promotion programs in developing countries

Do all exporters benefit the same from export promotion programs? Surprisingly, no matter how obvious this question may a priori be when thinking of the effectiveness of these programs, there is virtually no empirical evidence on how they affect export performance in different parts of the distribution of export outcomes. This paper aims at filling this gap in the literature. We assess the distributional impacts of trade promotion activities performing efficient semiparametric quantile treatment effect estimation on assistance, total sales, and highly disaggregated export data for the whole population of Chilean exporters over the 2002-2006 period. We find that these activities have indeed heterogeneous effects over the distribution of export performance, along both the extensive and intensive margins. In particular, smaller firms as measured by their total exports seem to benefit more from export promotion actions.     

Measuring China’s trade liberalization: A generalized measure of trade restrictiveness index

Neither simple average nor import-weighted average tariff indexes are ideal measures of tariff barriers. In this paper, we propose a generalized trade restrictiveness index (GTRI) that extends Feenstra’s (1995) tariff restrictiveness index (TRI) by relaxing the crucial assumption of a small open economy. We show that the GTRI can be measured using import tariffs, import shares, and the corresponding import and foreign export elasticities. We then apply the GTRI to examine how trade restrictiveness has evolved in China from 1997 to 2008, the period in which China entered the WTO. The GTRI indicates a higher level of protection than simple and import-weighted averages, but lower than the TRI. We further show a negative correlation between tariffs and product export supply elasticity, indicating that strategic trade policy was being pursued prior to China’s WTO accession. Finally, we calculate the welfare loss and terms-of-trade gain due to tariff protection. The overall tariff pass-through increases from around 28% to almost 47% because of the WTO.     

Do food standards affect the quality of EU imports?

This paper investigates the relationship between the diffusion of EU standards and product quality upgrading using highly disaggregated import data to the EU in the food industry. Results show that, on average, the diffusion of EU voluntary standards boosts the rate of quality upgrading. However, the results are heterogeneous when moving from primary to processed foods, and from ISO to non-ISO standards.     

Trade liberalization and economic growth: a case study of Iran

We estimate the impact of trade liberalization and physical and human capital accumulation on Iran’s economic growth during the period 1959?2007. Using co-integration techniques and a vector error correction model, we find a unique long-run relationship between economic growth and its major determinants. These determinants include the physical and human capital stock, the labor force, real non-oil exports, and import tariffs. In addition, the short-term error correction dynamics analysis suggests that trade liberalization has a significant long run positive role in dynamic of growth. Our results support the view that the integration of the Iranian economy with the world economy is undoubtedly welfare improving.     

Estimation of Armington elasticities in a CGE economy-energy-environment model for Europe

The main goal of the article is to estimate Armington elasticities of the energy and energy-intensive sectors of the GEM-E3 computable general equilibrium model. The model follows the standard two-stage budget optimisation of the consumer by first optimising between domestically produced and imported goods and, then, by country of origin. A panel data econometric framework is used here with dynamic adjustment to capture both the long and short term elasticities for the studied six aggregated sectors in Europe. The estimated long-term elasticities are in line with the literature, but higher than those used in the GEM-E3 model. The results suggest that consumer choice appears to be more price sensitive between the domestic and the composite imported goods, and amongst the importers, than already assumed in the model.     

The better you are the stronger it makes you: Evidence on the asymmetric impact of liberalization

This paper shows how trade liberalization can have an asymmetric effect on heterogeneous firms. It develops a neo-Schumpeterian growth model predicting that the impact of liberalization on economic performance is positive “on average”, but more advanced firms benefit more. These predictions are tested using Mexican plant-level data confirming that, under NAFTA, the liberalization spurred productivity growth on average. However, the empirical analysis goes beyond estimating the average effect of liberalization and shows that more advanced firms benefited disproportionately more from the liberalization. Focusing on the mechanisms explaining these results, the paper shows that the results are not just driven by an increase in input usage and investments, but rather by innovative and managerial efforts as they are significantly stronger in those sectors where the scope for innovative activities is larger.     

The determinants and impact of telecommunications reforms in developing countries

This paper has two related objectives. First, it seeks to identify the key determinants of some policies that have been at the heart of the reforms of the telecommunications industry in developing countries, namely, liberalization, privatization, and the (re)structuring of regulation. Second, it attempts to estimate the extent to which these policies have translated into actual deployment of telecommunications infrastructure. This simultaneous investigation is conducted by means of an econometric analysis of a 1985-1999 time-series-cross-sectional database on 86 developing countries. Sectoral as well as institutional and financial factors are found to be important determinants of the actual reforms implemented. We uncover a positive relationship between the decision to introduce competition in the digital cellular segment and the growth of the fixed-line segment, suggesting that these two segments have benefited from each other. We also find that countries facing increasing institutional risk and financial constraints are more likely to introduce competition in the digital cellular segment and to privatize the fixed-line incumbent, these policies being economically attractive to both investors and governments. In turn, these policies are those that enhance the deployment of fixed-line infrastructure. In contrast, competition in the analogue cellular segment and the creation of a separate regulator seem to be relatively less attractive policies as they are found to be less likely to be introduced in countries facing increasing institutional risk and budget constraints. Their impact on fixed network deployment is found to be negative or non significant.     

Determinants of vertical integration in export processing: Theory and evidence from China

This paper examines the determinants of vertical integration versus outsourcing in export processing, by exploiting the coexistence of two export processing regimes in China, which designate by law who owns and controls the imported components. Based on a variant of the Antràs-Helpman (2004) model, we show theoretically that control over imported components for assembly can affect firm integration decisions. Our empirical results show that when Chinese plants control the use of components, the export share of foreign-owned plants is positively correlated with the intensity of inputs provided by the headquarter (capital, skill, and R&D). These results are consistent with the property-rights theory of intra-firm trade. However, when foreign firms own and control the components, there is no evidence of a positive relationship between the intensity of headquarters' inputs and the prevalence of vertical integration. The results are consistent with our model that considers control over imported components as an alternative to asset ownership to alleviate hold-up by export-processing plants.     

Network Effects on Trade in Intermediate Goods: Evidence from the Automobile Industry

Growing production fragmentation makes the analysis of network effects on trade in intermediate goods more important than ever. The present study measures network effects on auto parts exports from 6 major auto producing countries using a panel data set covering 49 destinations and 31 products from 2002 to 2008. In contrast to prior research, the present study finds that in the case of Japanese automakers, overseas production by subsidiary plants is less important in determining auto parts exports from Japan than it is for the other major auto producing countries. Such uniqueness could be led by the higher reliance on domestic procurements of overseas subsidiaries of Japanese automakers as a result of the transfer of the vertical networks between automakers and parts suppliers formed in Japan.     

Foreign direct investment in services and manufacturing productivity: Evidence for Chile

This paper examines the impact of substantial foreign direct investment (FDI) inflows in producer service sectors on the total factor productivity (TFP) of Chilean manufacturing firms. Positive effects are obtained in firm fixed effects instrumental variables regressions and show that forward linkages from FDI in services explain 7% of the observed increase in Chile's manufacturing users' TFP. Our findings also suggest that service FDI fosters innovation activities in manufacturing. Moreover, we show that service FDI offers opportunities for laggard firms to catch up with industry leaders.     

Disaggregated data and trade policy analysis: The value of linking partial and general equilibrium models

Computable General Equilibrium (CGE) models are now routinely utilized for the evaluation of trade policy reforms, yet they are typically quite highly aggregated, which limits their usefulness to trade negotiators who are often interested in impacts at the tariff line. On the other hand, Partial Equilibrium (PE) models, which are typically used for analysis at disaggregate levels, deprive the researcher of the benefits of an economy-wide analysis, which is required to examine the overall impact of broad-based trade policy reforms. Therefore, a PE–GE, nested modeling framework has the prospect of offering an ideal tool for trade policy analysis. In this paper, we develop a PE model that captures international trade, domestic consumption and output, using Constant Elasticity of Transformation (CET) and Constant Elasticity of Substitution (CES) structures, market clearing conditions and price linkages, nested within the standard GTAP model. In particular, we extend the welfare decomposition of Huff and Hertel (2001) to this PE–GE model in order to contrast the sources of welfare gain in PE and GE analyses. To illustrate the usefulness of this model, we examine the contentious issue of tariff liberalization in the Indian auto sector, using PE, GE and PE–GE models. Both the PE and PE–GE models show that the imports of motorcycles and automobiles change drastically with both unilateral and bilateral tariff liberalization by India, but the PE model does a poor job predicting the overall size and price level in the industry, post-liberalization. On the other hand, the GE model overestimates substitution between regional suppliers due to “false competition” and underestimates the welfare gain, due to the problem of tariff averaging in the aggregated model. These findings are shown to be robust to wide variation in model parameters. We conclude that the linked model is superior to both the GE and PE counterparts.     

Trade liberalization and productivity dynamics: evidence from Canada

Abstract.  The paper investigates the productivity effects of the Canada-U.S. Free Trade Agreement on Canadian manufacturing. It finds that Canadian tariff cuts increased exit rates among moderately productive non-exporting plants. This led to the reallocation of market share towards highly productive plants, which explains the aggregate productivity gains observed when Canadian tariffs were reduced. The U.S. tariff cuts led to the within-plant productivity gains in exporters and, especially, new entrants into the export market. Any lack of output responses and labour-shedding as a consequence of the FTA was experienced by non-exporting plants, while exporters captured the gains from the FTA.     

Productivity effects of international outsourcing: evidence from plant-level data

Abstract.  We investigate the impact of international outsourcing on productivity using plant-level data for Irish manufacturing. Specifically, we distinguish the effect of outsourcing of materials from services inputs. Moreover, we examine whether the impact on productivity is different for plants being more embedded in international markets through exporting or being part of a multinational. Our results show robust evidence for positive effects from outsourcing of services inputs for exporters, either domestic or foreign owned. By contrast, we find no statistically significant evidence of an impact of international outsourcing of services on productivity for firms not operating on the export market.     

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.     

On the welfare effects of trade and investment liberalization

Using a three-factor knowledge- and physical capital model of trade and multinational activity, we consider a set of policy experiments to assess the welfare effects of trade and investment liberalization in general equilibrium. Specifically, we address the question of whether and under which circumstances a single versus a combined trade/investment liberalization strategy or a unilateral versus a bilateral policy change is preferable from a single country's and the world's point of view. The focus of this paper is to look at three relevant questions. First, when is investment liberalization beneficial and when is it harmful for a single economy or the whole world? Second, is pure investment liberalization a welfare maximizing strategy? Third, when is either kind of liberalization (trade, investment, or both) welfare improving and when neither of them?     

Greasing the wheels of international commerce: how services facilitate firms’ international sourcing

Abstract We use plant‐level data to study the link between the local availability of services and the decision of manufacturing firms to source materials from abroad. We develop a model to generate predictions about how the intensity of international sourcing of materials depends on the availability of services and firm characteristics. These predictions are supported by the data. Greater availability of services across regions, industries, and time increases firms’ foreign sourcing of materials relative to sales. The impact of services differs by firm type. National firms’ sourcing responds to changes in regional service conditions, whereas multinationals tend to be less affected.     

Financial liberalization and the relationship-specificity of exports

We investigate the causal impact of equity market liberalizations on sectoral export performance across 91 countries (1980–1997). The increased availability of external finance has boosted trade of industries that intensively use relationship-specific inputs, and lowered exports of industries using standardized inputs.     

On the evolution of institutional comparative advantages

This article investigates how comparative advantages have changed in the last 30 years. Using export data for 100 countries over the period 1976-2004, it provides evidence that comparative advantages are not static, but change over time. Focussing on three different sources of institutional comparative advantage, it shows that they display different trends over time. Additionally, it shows that these effects are generally stronger for OECD countries.     

A welfare analysis of unilateral trade and FDI liberalization

This paper uses a heterogeneous‐firms model to examine the pro‐competitive channel through which FDI affects national welfare. The model shows that the country from which FDI originates experiences a welfare gain following liberalization. However, a counterintuitive finding is that the welfare of the host country deteriorates. This is explained by the production relocation process that leads to an increase in the mass of domestic firms in the source country and a decrease in the host country. The model also confirms that unilateral trade liberalization brings a similar result even in the presence of bilateral FDI flows.
