Market access and technology adoption in the presence of FDI

This paper theoretically investigates whether improved access to the domestic market speeds up new technology adoption by foreign firms. Foreign firms choose between exporting and foreign direct investment (FDI) to serve the domestic market. If two firms compete in the domestic market, multilateral liberalization of FDI or the realization of multilateral free trade may deter or delay technology adoption, while they always promote and accelerate technology adoption if only a single firm serves the domestic market. Technology adoption can be quickest and consumer welfare greatest when the fixed cost of FDI and the trade costs are neither very high nor very low. Preferential liberalization of FDI promotes the technology adoption of the targeted firm but may not benefit consumers because it discourages technology adoption of the non-targeted firm.     

Trade between symmetric countries,heterogeneous firms,and the skill premium

Abstract This paper examines the effects of trade liberalization between symmetric countries on the skill premium. I introduce skilled and unskilled labour in a model of trade with heterogeneous firms à la Melitz (2003) and assume a production technology such that more productive firms are more skill intensive. I show that the effects of trade liberalization on wage inequality crucially depend on the type of trade costs considered and on their initial size. While fixed costs of trade have a potentially non‐monotonic effect on the skill premium, a drop in variable trade costs unambiguously and substantially raises wage inequality.     

Wage inequality, technology, and trade

The recent widening of wage inequality has been attributed by some to skill-biased-technical-change and by others to trade liberalization. This paper examines the two explanations within a unified model and also presents a new modeling of skill-biased-technical-change, where skilled workers replace unskilled ones. As a result technology adoption is endogenous and does not occur in all countries. Hence, wages for both types of workers, trade patterns and also factor productivities in all countries are endogenously determined. The model sheds light on the relationship between technology and trade, on the reasons for global productivity differences and on the causes for the recent rise in wage inequality.     

Political democratization, economic liberalization, and growth volatility

This study empirically investigates the effects of political and economic liberalization on growth volatility using a difference-in-difference method for a sample of 158 countries over the 1970-2005 period. The results show that, when examined separately, economic liberalization leads to a significant reduction in volatility while democratization is not followed by a decrease in growth volatility. For countries that undertake only one liberalization, opening up the economy to international trade reduces volatility in growth; becoming a democracy, on the other hand, seems to increase macroeconomic instability. For countries that implement both political and economic liberalizations, no statistically significant effect on volatility is detected. These results serve to provide additional support for the policy recommendation that developing countries should liberalize their economy first and then consider political liberalization.     

Heterogeneous firms,trade liberalization and agglomeration

Abstract In this study, we develop an economic model to examine agglomeration of heterogeneous firms following trade liberalization. In a closed economy, we show that high‐productivity firms are more likely to agglomerate because they benefit more from agglomeration than their low‐productivity counterparts. However, trade liberalization, especially with a high‐productivity partner, favours partial agglomeration; that is, low‐productivity firms relocate away from the region where high‐productivity firms agglomerate. Consequently, the welfare gap between the domestic regions of an economy narrows following trade liberalization. The latter result suggests that trade liberalization promotes regional economic development.     

Trade liberalization and credit constraints: Why opening up may fail to promote convergence

This paper examines credit constraints as one channel held responsible for hampering economic convergence between countries. Specifically, we extend a Melitz and Ottaviano ( 2008 ) type trade model with variable mark‐ups to allow for endogenous technology adoption. We consider a framework with two countries that potentially differ with respect to credit market development. Firms have the option to adopt a more efficient technology by paying some fixed cost that is more costly to finance for financially constrained firms. We find that technology adoption increases in both countries after trade liberalization but more so in the financially more developed country: the productivity gap widens. Simulations show that the welfare gap widens too. Opening up without sufficient access to external funding thus fails to promote convergence.     

Trade Liberalization and Heterogeneous Technology Investments

We propose a trade model where heterogeneous firms decide on a productivity‐enhancing technology investment. The model analyzes the impact of multilateral trade liberalization on firm‐ and industry‐level productivity. Freer trade increases the incentives to invest in technology by raising export profits. It also dampens these incentives, however, as profits stemming from domestic sales are reduced. Only exporters benefit from the former positive effect. The shape of the distribution of efficiency draws, the level of trade costs and the technology intensity of the industry are key elements removing the ambiguities regarding the net impact of trade liberalization.     

Distance to Frontier and New Import Growth

In a panel‐data study involving product‐level import data for 48 developing countries that underwent substantial trade liberalization between 1989 and 2001, this study finds that the growth of trade in new goods imported following major trade liberalization is related to the state of technology that existed just before liberalization. The study develops two new measures of the extensive margin. Findings indicate that greater is the distance of a country from the world technology frontier, the faster is its growth of new goods imports. This indicates a higher cost of trade protection for countries further away from the world technology frontier.     

CORRUPTION AND POLITICAL AND ECONOMIC REFORMS: A STRUCTURAL BREAKS APPROACH

In this paper we look at the impact of broad policy reforms on the levels of corruption. We use a structural break approach to identify country-specific time periods in which significant shifts in corruption levels take place. We then correlate these times of change with a set of covariates with specific focus on the impact of democratization, and trade and equity market liberalization. We find robust support for the hypothesis that episodes of reduction in corruption levels tend to be correlated with democratization and equity market liberalization.     

Relationship between trade openness and economic growth in Latin America: A causality analysis with heterogeneous panel data

We empirically analyze the causality relationship between economic growth and international trade using new advancements in the econometric methodology for heterogeneous panel data applied to Latin American countries. First, we test for dependencies between the units of cross‐section (countries) and then we test for cointegration between growth and openness. Finally, we test for Granger causality using a heterogeneous panel data test. The results reject the hypothesis of general, unidirectional, and homogeneous relationship between trade openness and economic growth in Latin American countries as a group. However, considering heterogeneity, we found significant evidence of causality from trade liberalization to economic growth in Chile, Peru, Nicaragua, and Uruguay; we have found bidirectional causality in Mexico and Honduras; and a causal relationship from economic growth to trade liberalization in Colombia, Costa Rica, Guatemala, and the Dominican Republic.     

The Interaction Between Technology Adoption and Trade When Firms are Heterogeneous

This paper develops a monopolistic competition model with heterogeneous firms to study the interaction between technology adoption and trade in a world of two countries facing different technology adoption costs. It shows that a reduction in the technology adoption cost in one country increases productivity, induces more firms to adopt advanced technology, and improves welfare in this country, while decreasing productivity, inducing more firms to switch back to old technology, and reducing welfare in the other country. Furthermore, although a reduction in transport costs always makes the country with the lower adoption cost better off, it can hurt the other country.     

NO CREDIT,NO GAIN: TRADE LIBERALIZATION DYNAMICS,PRODUCTION INPUTS,AND FINANCIAL DEVELOPMENT

We study the role of financial development on the aggregate implications of reducing import tariffs on capital and intermediate inputs. We document empirically that financially underdeveloped economies feature a slower aggregate response following trade liberalization. To quantify these effects, we set up a general equilibrium model with heterogeneous firms subject to collateral constraints and estimate it using Colombian plant-level data. We find that low financial development substantially limited the gains from trade liberalization in Colombia in the early 1990s. More broadly, we find that low financial development substantially limits both the aggregate and welfare gains from tariff reductions.     

Skills scarcity and export intensity

We describe a model of trade with skills-based product differentiation and non-proportional trade costs that predicts a positive correlation between firms' export intensity, the price of their exports and the wages they pay to their workers. In equilibrium, firms that employ workers with comparatively scarcer skills export a larger proportion of their output, pay higher wages and charge higher prices. In line with empirical evidence, the model predicts that trade liberalization can cause the distribution of earnings to become more polarized, with patterns that reflect the heterogeneous effects of trade liberalization on firms' export performance.     

Multi-product firms,heterogeneous quality and exporting behaviour: product-level evidence from the movie industry

This article examines how quality affects heterogeneous multiple-product firms’ exporting behaviours. We develop a structural model of the global movie market, including both consumers’ movie demand choices and firms’ exporting decisions. A movie studio is a multi-product firm that releases many movies within a year. We model movie quality as a combination of firm-level appeal and product-level attractiveness. We find that both studio-level and movie-level heterogeneity affect demand for movie, and movie-level heterogeneity is relatively more important. We also explore the counterfactual effects of quality improvement and trade liberalization on trade. Our results show that improvement of quality increases both intensive margin and extensive margin of trade. By elimination of quota, we find that trade liberalization increases movie exports to a foreign market by 19%. The results of our study can also help improve understanding of trade in the service industry. For instance, we do not find a positive correlation between the foreign entry costs and the geographic distance, as in the case of manufacture goods.     

Trade in goods and services: Two sides of the same coin?

This study analyzes the interrelationship between goods and services in production and trade using the most recent input–output tables for all OECD countries. It first describes the role of services in production and trade in goods. Next, it proposes two models for analyzing the impact of services trade liberalization on industrial structure. The first captures the role of trade in tasks when countries have different technology i) in production of services; and ii) in organizing production. The latter has to the author's knowledge not been analyzed in the trade literature before. Countries with superior organizational technology (e.g. Japan) will strengthen their comparative advantage in manufacturing following trade liberalization in services. The second model explores the interrelationship between intermediate goods and services i) when they are substitutes; and ii) when they are complements. In both models the gains from trade liberalization is non-linear in trade costs. Going the last mile of liberalization has a much larger impact than taking the first steps.     

Trade Liberalization with Heterogeneous Firms

This paper examines the various aspects of trade liberalization with heterogeneous firms using the Melitz (2003 ) model. We find a number of novel results and effects including a Stolper–Samuelson‐like result and several results related to the volume of trade, which are empirically testable. We also analyze what might be called an anti‐variety effect as the result of trade liberalization. We show that this effect is most pronounced for small countries. This resonates with the often voiced criticism from antiglobalists that globalization leads the world to become more homogeneous by eliminating local specialties. Nevertheless, we find that trade liberalization always leads to welfare gains in the model.     

Globalization,Worker Mobility and Wage Inequality

In the present paper, I integrate frictional labor markets with on‐the‐job search into an otherwise standard heterogeneous firm model of intra‐industry trade. Most importantly, I show that the returns to workers' inter‐firm mobility are higher in a trade equilibrium than in autarky. Intuitively, by favoring large and productive firms, international trade amplifies the disparities in profitability between small and large firms. Hence, the returns to labor reallocation across firms rise. In view of the empirically observed higher inter‐firm mobility among high‐skill workers, this suggests a skill‐biased impact of trade liberalization.

3D printing,international trade,and FDI

We analyze the relationship between 3D printing technology, the volume of trade, and the structure of foreign direct investment (FDI). We present a standard trade model with firm-specific heterogeneity into which we include 3D printing as a technology choice for foreign direct investment. The model generates three predictions. First, 3D printers are introduced in areas with high economic activity that face high transport costs. Second, technological progress in 3D printing leads to FDI dependent on traditional techniques gradually being replaced by FDI based on 3D printing. Third, with wider adoption, further technological progress in 3D printing leads to a gradual replacement of international trade. Empirical evidence focusing on the sectors with the highest rates of adoption supports the first hypothesis, while evidence from a case study supports the second and third. Our results suggest that the traditional strategy of poor countries for export-led industrialization is threatened by the widespread adoption of 3D printing that replaces international trade.     

MARKET ACCESS,INVESTMENT, AND HETEROGENEOUS FIRMS*

This article presents a model of international trade in which heterogeneous firms can expand through capital acquisitions. I show that demand elasticities are a crucial element in predicting which firms invest, in what location, and for what reason. High‐productivity firms, who tend to sell goods at a low elasticity, invest for market access (tariff jumping). Middle productivity firms, who tend to sell at a higher elasticity, invest for productivity improvement. The relative value of trade costs dictates which incentive is larger. In equilibrium, trade liberalization can reduce aggregate productivity by reducing an important source of investment demand: foreign firms.
