An open economy general equilibrium model with heterogeneous producers, a homothetic utility function and endogenous elasticity

Recent monopolistic competition models have identified three main sources of the gains from trade: (1) the introduction of new varieties for consumers, (2) an improvement in efficiency through the exit of low-productivity firms, and (3) a reduction in firms’ markups through import competition. In this paper, we extend Feenstra (Economics Letters, 78(1):79–86, 2003) to develop a model with producers heterogeneous in productivity to capture these gains. Here, firm markups are decreasing with market share, and trade introduces new varieties to consumers and reduces the market share of domestic firms. This reduces markups and profits and forces low-productivity firms to exit. This pro-competitive effect on the distribution of productivity contrasts with the conventional export-driven mechanism in a constant elasticity setup. We can usefully extend this model for further study because of the homotheticity of the utility function and the tractability of the model.     

The spatial effects of trade openness: a survey

This paper surveys the literature on the implications of trade liberalisation for intra-national economic geographies. Three results stand out. First, neither urban systems models nor new economic geography models imply a robust prediction for the impact of trade openness on spatial concentration. Whether trade promotes concentration or dispersion depends on subtle modelling choices among which it is impossible to adjudicate a priori. Second, empirical evidence mirrors the theoretical indeterminacy: a majority of cross-country studies find no significant effect of openness on urban concentration or regional inequality. Third, the available models predict that, other things equal, regions with inherently less costly access to foreign markets, such as border or port regions, stand to reap the largest gains from trade liberalisation. This prediction is confirmed by the available evidence. Whether trade liberalisation raises or lowers regional inequality therefore depends on each country’s specific geography.     

Are China's trade interests overestimated? Evidence from firms’ importing behavior and pollution emissions

Importing is an important driving force for a country's economic growth. While importing promotes the expansion of economic scale, does it also lead the increase of pollution emissions in production? In this paper, we establish a micro theoretical model to analyze the impacts of importing on firms’ environmental performance, and then use the data of China's manufacturing firms for empirical tests. We show that the importing of intermediate goods or capital goods will lead to the increase of firms’ production scale, and thereby increasing their total emissions, which suggests that China's environment will be deteriorated by importing. On the other hand, importing also has some positive environmental effects that firms will increase their abatement investment after importing intermediate goods or capital goods, thus firms’ emission intensity can be effectively reduced. Altogether, this paper provides important evidence on the impacts of importing on pollution emissions at product-level. We suggest that when analyzing China's interests in trade, the environmental effects of trade should be taken into consideration, otherwise China's gains from trade will be overestimated. This paper also has important implications that while developing the economy through international trade, the government should strengthen environmental protection and advocate green trade.     

Powerless: gains from trade when firm productivity is not Pareto distributed

Most trade models featuring heterogeneous firms assume a Pareto productivity distribution, on the basis that it provides a reasonable representation of the data and because of its analytical tractability. However, recent work shows that the characteristics of the productivity distribution crucially affect the estimated gains from trade. This paper thoroughly compares the gains from trade obtained under three different productivity distributions (Pareto, lognormal, and Weibull) and investigates their policy implications. We find that both the magnitude of the welfare gains and the relative importance of the fixed versus variable trade costs change significantly. Hence, relying blindly on a single distribution is dangerous when performing trade policy analysis.     

Dynamic estimation of the relationship between trade openness and output growth in Asia

This paper studies the relationship between trade openness and output growth for a sample of twenty-three Asian countries using both a static OLS and a dynamic ECM estimation models. At the country specific level, the findings of this study provide robust empirical evidence indicating that higher revealed trade openness is not the main engine explaining the Asian economic-growth miracle. In particular, the authors find that physical capital accumulation is at the core of the observed long-run output per worker growth. At the regional level, the authors observe a marked difference between the pre and post 1997–1998 financial crisis, whereas, in the post period, trade openness has a positive and significant effect on output growth. In general, the results from the dynamic estimations prove that the conventional OLS static estimates underestimate the effect of investment on output growth. In addition, the dynamic model allows for a separation of gains from trade between short term and long term. The paper results also provide evidence in support of the idea that, countries with a growing degree of trade openness may experience faster per-capita output growth through gains in productivity associated to capital accumulation, rather than the assumed technological spillover effects from the trading sector. Again, at the regional level in the post financial crisis period both short term and long term gains from trade are relevant to growth. Why more trade does not necessarily imply faster growth at all levels of revealed trade openness growth, remains a conundrum.     

The effect of tariff reductions on firm size and firm turnover in canadian manufacturing

Using panel data on 81 Canadian manufacturing industries over the 1983–1996 period, the authors show that the estimated impact of recent tariff cuts was a positive and significant increase in the exit rate of firms. Supplementing this finding with recent research showing, that exiting firms tend to be less productive than those that survive, this provides support for recent trade models asserting that increased exposure to international trade induces the exit of least efficient firms, thereby contributing to productivity growth.

Trade liberalization and wage inequality: Evidence from Korea

This paper investigates the heterogeneous income distribution effects of trade liberalization using Korean survey data from years of 2000–2015. Following the Stolper-Samuelson theorem most of previous research studying the effects of trade liberalization on wage differences focus on workers’ characteristics (e.g., skilled or unskilled) while heterogeneity within the same worker group has not been yet substantially investigated. To fill this gap, this paper provides empirical evidence of wage inequality across firms within the same group of workers caused by trade liberalization, potentially implied in the new-new trade models with firm heterogeneity. Employing a difference-in-differences (DID) specification, we find that the wages of unskilled workers in Korea have increased since its FTAs with more advanced countries, such as members of EU and the US, came into effect, while the effects on the wages of skilled workers are negative but not statistically significant. We also show that wage effects are heterogeneous across firms within unskilled and skilled worker groups, while the positive effects are statistically significant and largest for unskilled workers in medium-large sized firms. These findings are in line with both traditional and new-new trade models.     

INFRASTRUCTURE QUALITY AND MANUFACTURING EXPORTS IN AFRICA: A FIRM‐LEVEL ANALYSIS

Using bilateral trade flow models, a body of empirical work has documented how geography and infrastructure variables affect trade performance. However, in this paper, we apply censored regression models like the Tobit and Probit on firm‐level manufacturing data from 10 African countries, and results suggest that inadequate infrastructure in the form of customs, transport, electricity and water negatively affects export intensity and participation. Owning a generator and private water source also appear to have a significant impact on exports. This, therefore, means that firms can minimise the impact of power and water disruption on production, and hence trade by installing these alternative energy and water sources.     

Do domestic and foreign exporters differ in learning by exporting? Evidence from China

In view of the importance of intra-firm trade and export-platform FDI conducted by multinationals, we investigate how domestic firms and foreign affiliates exhibited differential impacts of export entry and exit on productivity changes. Using a comprehensive dataset from China's manufacturing industries, we employ the Olley–Pakes method to estimate firm-level TFP and the matching techniques to isolate the impacts of export participation on firm productivity. Robust evidence is obtained that domestic firms displayed significant productivity gains (losses) upon export entry (exit), whereas foreign affiliates showed no evident TFP changes. Moreover, the productivity gains for domestic export starters were more pronounced in high- and medium-technology industries than in low-technology ones. We explain our findings from the perspective of the technology gap theory after considering processing trade and the fragmentation of production stages in the era of globalization.     

Understanding Cross-Country Differences in Exporter Premia: Comparable Evidence for 14 Countries

We use comparable micro level panel data for 14 countries and a set of identically specified empirical models to investigate the relationship between exports and productivity. Our overall results are in line with the big picture that is by now familiar from the literature: exporters are more productive than non-exporters when observed and unobserved heterogeneity is controlled for, and these exporter productivity premia tend to increase with the share of exports in total sales; there is evidence in favour of self-selection of more productive firms into export markets, but nearly no evidence in favour of the learning-by-exporting hypothesis. We document that the exporter premia differ considerably across countries in identically specified empirical models. In a meta-analysis of our results we find, consistent with theoretical predictions, that productivity premia are larger in countries with lower export participation rates, with more restrictive trade policies, lower per capita GDP, less effective government and worse regulatory quality, and in countries exporting to relatively more distant markets.

Trade Reform and Manufacturing Pricing Behavior in Four Archetype Asia‐Pacific Economies*

General equilibrium models are constructed of four Asia‐Pacific economies that differ according to their levels of development, the comparative sizes of their manufacturing sectors and their patterns of comparative advantage and trade protection. The countries chosen are Australia, an industrialized importer of manufactures; Japan, an industrialized exporter; the Philippines, a developing importer; and the Republic of Korea, a developing exporter. Manufacturing industries are characterized as comprising identical oligopolistic firms producing homogeneous goods that are differentiated from competing imports. Oligopoly behavior notwithstanding, trade reforms are found to yield conventional results in that net economic gains are small while implicit transfers are substantial. More competitive (non‐collusive) pricing by oligopolistic firms, which might be achieved through reform of competition law and trade practices surveillance, yields larger net gains and these gains tend to accrue to all domestic primary factors. Such reforms also yield substantial interaction between oligopoly behavior and economic and industrial structure.     

Economic performance and international trade engagement: the case of Portuguese manufacturing firms

By combining economic and financial data for Portuguese manufacturing firms with data on their exports and imports, we uncover some aspects of the relationship between international trade engagement and firms’ performances. In line with recent theoretical and empirical developments in the international trade literature: (i) we testify that Portuguese international trade is highly concentrated, especially on the import side, and both in inter- and intra-sector terms; (ii) we corroborate previous studies and theses according to which two-way traders outperform only importers, only exporters and above all domestic firms; (iii) we find that the greater the diversification of markets and goods (especially with regard to imports), the better the performance achieved by internationalised firms; (iv) we notice that the higher the intensity of firms’ international trade (especially imports), the better their performance; (v) we also present evidence that destination markets for exports and origin markets for imports are also important in explaining firm’s performance.     

Trade in Parts and Components and the Industrial Geography of Central and Eastern European Countries

Growing inflows of FDI and the increasing integration of domestic firms into International Production Networks (IPNs) set up by EU-15 partners have yielded a rise in trade in parts and components for Central and Eastern European Countries (CEECs). As a consequence, new patterns of localization of industrial activities have been observed in the region since the mid-1990s. In this paper, I propose a comprehensive model of trade and production which tries to explain cross-country variations of sectoral output by comparative advantages (Ricardo, Heckscher–Ohlin) and agglomeration forces (home market effect, market potential), with a focus on the role played by trade in middle products. The empirical implementation reveals that the higher is the involvement in IPNs the larger is the domestic share of regional output. Comparative advantages are a crucial determinant of localization as opposed to agglomeration forces. I argue that these results can be interpreted as an assessment of the predictive power of two alternative trade theories. JEL no.  F10, F12, F14, F15     

Integration and the export behaviour of firms: Trade costs,trade volumes and welfare

Integration and the Export Behaviour of Firms: Trade Costs, Trade Volumes and Welfare. - This paper analyses a model in which, because of fixed costs associated with exporting, only a proportion of firms in an industry engage in international trade. Economic integration (a reduction in trade costs) increases the proportion of firms trading and reduces the total number of active firms as relatively small non-trading firms are replaced by larger trading firms. There are welfare gains from integration, but because of the adverse effects of integration on the total population of firms these gains are smaller than in the standard model where all firms export.     

The Determinants of Intrafirm Trade: In Search for Export-Import Magnification Effects

This paper studies the determinants of Austrian bilateral intrafirm trade in a panel of industry-level intrafirm goods trade flows. Economic size, unit labor costs and the magnification effects originating from multiple border crossing of sequentially finished products are found to be the most important determinants of trade within multinational firms. Especially, our evidence lends support to multiple border crossing of sequentially finished products, an argument that has recently been put forward in the outsourcing literature. JEL no.

Entering new country and product markets: does export promotion help?

Entering new export markets is primarily a discrete choice. Even though several empirical papers have used modeling strategies consistent with this fact, no study has examined the effects of public policies aimed at affecting this decision within this setting. In this paper we assess the impact of trade promotion activities on export outcomes using trade support and highly disaggregated export data for the entire population of exporters of Uruguay, a small developing country, over the period 2000–2007 to estimate a binary outcome model that allows for unobserved heterogeneity. We find that trade supporting activities have helped firms reach new destination countries and introduce new differentiated products.     

How the Internet Promotes China's Exports: A Firm‐level Perspective

The development of information and communications technology (ICT), particularly the Internet, has reduced trade costs. However, it remains unclear whether these reduced costs are reflected in the “extensive margins” of firms’ exports (which refer to the probability of firms exporting) or the “intensive margins” (which refer to the value of firms’ export). To test this, we used the concepts of information cost and binary margins, an augmented trade model of firm heterogeneity, a two‐stage Heckman estimation, and data from the World Bank Enterprise Survey of Chinese firms in 2012. The results revealed that reduced trade costs from the use of ICT were positively related to extensive margins but that the connection with intensive margins was not significant. The results lead to the conclusion that reduced information costs related to a firm's exporting behavior were primarily reflected in variable trade costs. This study offers theoretical and empirical evidence for China's policies towards the Internet, which are relevant for the export of manufactured goods. The government should encourage the use of ICT to enhance firms’ export opportunities while facing current trade policy uncertainty.     

Dynamic Links Between Unexpected Exchange Rate Variation, Prices, and International Trade

This paper investigates dynamic interrelations between exchange rate uncertainty, international trade, and trading competitiveness in prices, using UK data. The empirical results derived from vector autoregressive (VAR) models show that a shock to exchange rate volatility negatively affects trade volumes, and such negative effects are greater than the effects on trade price levels.

How Important Is Trade and Foreign Ownership in Closing the Technology Gap? Evidence from Estonia and Slovenia

This paper focuses on the impact that the different methods of privatization implemented in Estonia and Slovenia might have had on the pattern of technology transfer to domestic firms through either FDI or international trade. We develop an empirical model that looks at three aspects of the problem: the importance of direct and indirect effects of FDI; the role of local absorptive capacity; and the role of trade in technology transfer. The study finds that the method of privatization does influence the way a firm obtains technology from abroad: Estonia, which attracted a considerable amount of FDI through its privatization programme, used this channel to gain direct access to global markets for technology, while Slovenia discouraged sales of state enterprises to multinational firms and inclined domestic firms to use trade flows to gain access to these markets.

Efficiency spillovers from foreign direct investment in the EU periphery: A comparative study of Greece,Ireland, and Spain

Despite a growing number of empirical studies on efficiency spillovers arising from the presence of multinational firms for a number of countries, general conclusions on this issue have been inhibited by differences in the data sets and estimation techniques used across studies. In this paper we conduct a comparative empirical study for Greece, Ireland and Spain by creating comparable data sets and estimating identical models. Our results show evidence of spillovers in Ireland and Spain only, although these positive spillovers seem to depend on whether firms have the absorptive capacity to capture technological spillovers and the criteria used to classify them as foreign affiliates.
