Does international openness affect the productivity of local firms?

This paper examines how international openness can change firm productivity in south‐eastern Europe (SEE), a crucial question for middle‐income countries. Using firm‐level data for six transition economies over the 1995–2002 period, we identify whether foreign ownership and propensity to trade with more advanced countries can bring about higher learning effects. We find that: (i) foreign ownership has helped restructure and enhance the productivity of local firms in four out of six countries; (ii) exporting to advanced markets has a larger impact on productivity growth in four countries, especially when the firm's absorptive capacity is taken into account; (iii) in contrast, exporting to the less competitive markets of the former Yugoslavia seems to negatively affect productivity growth in three countries; and (iv) learning effects from importing are similar to those from exporting. Our results suggest that trade liberalization is not uniformly beneficial. Regional composition of trade flows and absorptive capacity of local firms matter. Thus, trade liberalization within the SEE region may not provide a substitute for a general trade liberalization which includes access to the more competitive markets of countries belonging to the Organization for Economic Co‐operation and Development.     

Trade liberalization,forward‐looking firms,and welfare

We set up an oligopolistic model with two exporting firms selling to a third market to investigate the welfare implications of trade liberalization when the exporting firms are forward‐looking. The results show that with cost asymmetry trade liberalization encourages the exporting firms to engage in tacit collusion, which may not only be detrimental to the domestic welfare, but also to the consumer surplus of the importing country. Moreover, we find that tacit collusion is less sustainable if the government of the importing country imposes a lower (higher) tariff on the more (less) efficient exporting firm. If a nonforward‐looking or a forward‐looking cost‐efficient domestic firm exists in the importing country, then trade liberalization also encourages tacit collusion.     

Trade,Wage Gaps,and Specific Human Capital Accumulation*

We develop a new framework for the analysis of the impact of trade liberalization on the wage structure and on welfare. Our model focuses on the decision of workers to accumulate firm‐specific skills, by “on‐the‐job” training, knowing that this means their future wages will have to be negotiated, and that the outcome of negotiation will depend on the profitability prospect of firms operating in a new trading environment. We show that trade liberalization may reduce the welfare of a developing country because of its adverse effect on skill accumulation. We also explore the effects of trade liberalization on the wage gap between skilled and unskilled workers.     

Trade, regulations, and income

We examine the relationship between openness and per-capita income using cross-country data from 126 countries. We find that trade leads to a higher standard of living in flexible economies, but not in rigid economies. Business regulation, especially on firm entry, is more important than financial development, higher education, or rule of law as a complementary policy to trade liberalization. Specifically, after controlling for the standard determinants of per-capita income, our results imply that a 1% increase in trade is associated with more than a one-half percent rise in per-capita income in economies that facilitate firm entry, but has no positive income effects in more rigid economies. The findings are consistent with Schumpeterian “creative destruction”, which highlights the importance of new business entry in economic performance, and with previous firm-level studies showing that the beneficial effects of trade liberalization come largely from an intra-sectoral reallocation of resources.     

贸易自由化、纵向关联市场与战略性环境政策——环境税对发展绿色贸易的意义

本文在一个两国出口至第三国的连续双寡模型中,研究贸易自由化对均衡环境政策及社会福利的影响。分析发现:(1)战略性环境政策的租金攫取效应可通过中间产品出口实现,但不一定会通过最终产品出口实现。(2)当污染的环境损害程度不大时,贸易自由化将降低各国环境税,从而使各国的环境保护出现"向底线赛跑";当环境损害系数较大时,贸易自由化将提高各国环境税。(3)社会福利水平为双边关税壁垒的凹函数(呈"倒U型"),贸易自由化对社会福利的影响不确定。此外,本文还分析了合理征收环境税对发展我国绿色贸易的意义。     

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.     

Trade liberalization and volatility: Evidence from Indian firms

I look at the impact of trade liberalization on sales growth volatility of firms. Exploiting India’s externally imposed trade reform to identify trade liberalization effects, I find that while a fall in the tariff on the final product produced by the firm is associated with an increase in volatility in Indian manufacturing firms, a fall in the tariff on intermediate inputs is associated with a decrease in volatility, with the latter effect dominating the former. I hence propose an additional channel for gains from trade liberalization to the ones documented in the literature.     

Privatization,Underpricing, and Welfare in the Presence of Foreign Competition

We analyze privatization in a differentiated oligopoly setting with a domestic public firm and foreign profit‐maximizing firms. In particular, we examine pricing below marginal cost by the public firm, the optimal degree of privatization, and the relationship between privatization and foreign ownership restrictions. When market structure is exogenous, partial privatization of the public firm improves welfare by reducing public sector losses. Surprisingly, even at the optimal level of privatization, the public firm's price lies strictly below marginal cost, resulting in losses. Our analysis also reveals a potential conflict between privatization and investment liberalization (i.e., relaxing restrictions on foreign ownership) in the short run. With endogenous market structure (i.e., free entry of foreign firms), partial privatization improves welfare through an additional channel: more foreign varieties. Furthermore, at the optimal level of privatization, the public firm's price lies strictly above marginal cost and earns positive profits.     

Credit Constraints,Technology Choice and Exports: A Firm‐level Study for Latin American Countries

In this paper, constraints on technology choice and credit access are introduced into a firm‐level trade model in a dynamic setting in order to explain factors that limit benefits to a firm from trade liberalization. Theoretical analysis shows that firms face credit constraints depending on their initial productivity and the cost of credit. As a result, credit‐constrained firms may not be able to cross the minimum productivity threshold needed to enter and compete in a foreign market. Empirical analysis using firm‐level panel data for six Latin American countries confirms that financial constraints negatively influence firms' export and investment decisions.     

Firm exit,technological progress and trade

The dynamics of export market exit and firm closure have found limited attention in the new heterogeneous-firms trade literature. In fact, several of the predictions on firm survival and exit stemming from this new class of models are at odds with the stylized facts. Empirically, higher productivity firms survive longer, most firm closures are young firms, higher productivity exporters are more likely to continue to export compared to less productive exporters and market exits as well as firm closures are typically preceded by periods of contracting market shares. The present paper shows that the simple inclusion of exogenous economy wide technological progress into the standard Melitz (2003) model generates a tractable dynamic framework that generates endogenous exit decisions of firms in line with the stylized facts. Furthermore, we derive the effects of faster technological progress and trade liberalization on export market exit and firm closure.     

Trade Liberalization and Productivity Growth

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.     

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.     

Quota removal and firm-level offshoring: Theory and evidence

Recent literature indicates that offshoring can effectively increase firm productivity and improve product quality. Therefore, global value chains have increased in importance. In this paper, we investigate the impact of export growth on firm-level offshoring. Removal of the quota on textile and clothing products in importing countries boosts China's exports of quota-restricted products. This removal offers a quasi-natural experiment. Using a difference-in-differences approach, we find that export growth induced by the quota removal increases the extensive and intensive margins of firm-level offshoring. The impact is more pronounced on domestic firms and firms that are engaged in ordinary trade. Our findings suggest additional gains from trade liberalization: trade liberalization not only boosts exports, but also enhances firm productivity and product quality through encouraging firm-level offshoring.     

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 Liberalization and Firm Productivity: Evidence from Chinese Manufacturing Industries

This paper examines the impact of tariff reduction following China's World Trade Organization (WTO) entry on the productivity of Chinese manufacturing firms using a firm‐level panel database that comprises all of China's manufacturing firms with an annual turnover above 5 million yuan and that spans the period of 2000–2006. An instrumental variable estimator is used to account for the endogeneity of the tariff reduction. The results indicate that China's trade liberalization in the five years following its WTO entry has led to a 0.94% annual increase in total factor productivity for Chinese manufacturing firms. However, the overall productivity gain from the tariff reduction is a net result of a productivity depressing effect of output tariff reduction and a productivity enhancing effect of input tariff reduction. Both effects have diminished in magnitude over the years after China joined the WTO. Firm heterogeneity and turnover plays an important role in generating gains from trade liberalization. The surviving firms have managed to cope with and take advantage of lower tariffs. The extent to which the tariff reduction affects Chinese firms' productivity is also dependent on the ownership structure of the firms with foreign‐invested firms being the clear winner.     

Learning How To Export

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption: it takes time for firms to learn how to export. It is known that the welfare gains from trade liberalization implied by a large class of models like the Armington gravity model, the Krugman model, and the Melitz model are small. Our quality ladders model is consistent with a number of firm‐level stylized facts from the heterogeneous firms trade literature and is, in addition, capable of generating very large welfare gains from trade liberalization.     

The Impact of Input and Output Tariffs on Firms' Productivity: Theory and Evidence

This paper studies the impact of trade liberalization on productivity. It shows that when intermediate inputs are not highly differentiated, lowering input tariffs leads to a rise in within‐firm productivity and wages, and lowering output tariffs has the opposite effect. When intermediate inputs are highly differentiated, the conclusions reverse. These predictions are supported by the data, given by the industrial survey from INEGI (Mexico's Insitituto Nacional de Estadistica Geografia e Informacion) in the period 1984–90. The paper yields estimates for the elasticity of substitution among intermediate inputs, which are useful in determining the direction of the impact of trade liberalization. These estimates can be used to assess the gains from trade liberalization.     

Deep trade agreements and vertical FDI: The devil is in the details

Although pre‐1990s preferential trade agreements focused mostly on tariff liberalization, recent agreements increasingly contain deep provisions in diverse areas, such as intellectual property rights, investment and standards. At the same time, there has been a remarkable increase in the internationalization of production through foreign direct investment and outsourcing. This paper studies how deep trade agreements affect the international organization of production. Using new measures of the depth and content of preferential trade agreements and of vertical foreign direct investment, the analysis finds evidence that the depth of trade agreements is correlated with vertical foreign direct investment. Furthermore, this relationship is driven by the provisions that improve the contractibility of inputs provided by suppliers, such as standards, while provisions that increase the contractibility of headquarter services, such as intellectual property rights and investment protection, are generally negatively correlated with foreign investment. This finding is consistent with the so‐called “property rights” theory of the multinational firm according to which improving the contractibility of an input reduces the importance of giving incentives through ownership.     

The Effects of Trade Liberalization in a Vertical Structure

Despite the importance of international trade on intermediate goods, the literature did not pay much attention to this aspect in determining the effects of trade liberalization in the presence of a labor union. We take up this issue here and show the effects of trade liberalization on the final goods and/or the intermediate goods, where the domestic firm pays unionized wage and imports intermediate goods. We show that trade liberalization on the intermediate goods (final goods) increases (decreases) the unionized wage, labor union's utility and domestic profit. Trade liberalization on both the final goods and intermediate goods may either increase or decrease the domestic unionized wage, labor union's utility and domestic profit depending on the input coefficients and the initial tariff levels. Our qualitative results are robust with respect to the intermediate goods market structure, the pricing strategy of the intermediate goods producers and the union's objective function.     

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.
