Firm-level comparative advantage

We study the consequences of heterogeneity in factor intensity on firm performance. We present a standard Heckscher–Ohlin model augmented with factor intensity differences across firms within a country–industry pair. We show that for any two firms, each of whose capital intensity is, for instance, one percent above (below) its respective country–industry average, the relative marginal cost of the firm in the capital-intensive industry of the capital-abundant country is lower (higher) than that of the other firm. Our empirical analysis, conducted using data for a large panel of European firms, supports this prediction. These results provide a novel approach to the verification of the Heckscher–Ohlin theory and new evidence on its validity.     

Ricardian-Heckscher-Ohlin comparative advantage: Theory and evidence

This paper derives and estimates a unified and tractable model of comparative advantage due to differences in both factor abundance and relative productivity differences across industries. It derives conditions under which ignoring one force for comparative advantage biases empirical tests of the other. I emphasize two empirical results: First, factor abundance- and relative productivity-based models each possesses explanatory power when nesting the other as an alternate hypothesis. Second, productivity differences across industries do not bias tests of the HO model in my sample. However, I find weak and mixed evidence that Heckscher-Ohlin forces can potentially bias tests of the Ricardian model.     

Unobservable skill dispersion and comparative advantage

This paper investigates a theoretical mechanism linking comparative advantage to the distribution of skills in the working population. We develop a tractable multi-country, multi-industry model of trade with unobservable skills in the labour market and show that comparative advantage derives from (i) cross-industry differences in the substitutability of workers' skills and (ii) cross-country differences in the dispersion of skills. We establish the conditions under which higher skill dispersion leads to specialization in industries characterized by higher skill substitutability across tasks. The main results are robust when the model is extended to allow for partial observability of skills. Finally, we use distributions of literacy scores from the International Adult Literacy Survey to approximate cross-country productivity differences due to skill dispersion and we carry out a quantitative assessment of the impact of skill dispersion on the pattern of trade.     

On the origins of comparative advantage

This paper proposes a simple theory of international trade with endogenous productivity differences across countries. The core of our analysis lies in the determinants of the division of labor. We consider a world economy comprising two large countries, with a continuum of goods and one factor of production, labor. Each good is characterized by its complexity, defined as the number of tasks that must be performed to produce one unit. There are increasing returns to scale in the performance of each task, which creates gains from specialization, and uncertainty in the enforcement of each contract, which create transaction costs. The trade-off between these two forces pins down the size of productive teams across sectors in each country. Under free trade, the country where teams are larger specializes in the more complex goods. In our model, it is the country where the product of institutional quality and human per worker capital is larger. Hence, better institutions and more educated workers are complementary sources of comparative advantage in the more complex industries.     

Unpacking sources of comparative advantage: A quantitative approach

This paper develops an approach for quantifying the importance of different sources of comparative advantage, by extending the Eaton and Kortum (2002) model to predict industry trade flows. In this framework, comparative advantage is determined by the interaction of country and industry characteristics, with countries specializing in industries whose production needs they can best meet with their factor endowments and institutional strengths. I estimate the model parameters using: (i) OLS; and (ii) a simulated method of moments procedure that accounts for the prevalence of zeros in the bilateral trade data. I apply the model to explore various quantitative questions, such as how much distance, Ricardian productivity, factor endowments, and institutions each matter for country welfare in the global trade equilibrium.

Export industry policy and reputational comparative advantage

Country-of-origin reputations are endogenized in this paper and it is shown that otherwise identical countries can be correctly perceived as differing in their percentage of high-quality producers. These self-fulfilling reputations determine not only the average quality of a country’s exports but also the type of products in which a country specializes. Hence, the pattern of international trade can be determined by this ‘reputational comparative advantage’. An inferior country-of-origin reputation leads to lower national welfare, therefore, several trade and industrial policies that can improve country-of-origin reputation are examined.     

Factors influencing United States comparative advantage

One of the more famous results in international trade is Leontief's demonstration that the conventional wisdom of trade theory—the two-factor Heckscher-Ohlin model, coupled with the empirical judgement that the U.S. is capital-rich—does not appear to provide an explanation of the composition of U.S. trade. A major conclusion of many recent studies is that an adequate model of comparative advantage will be, of necessity, a multi-factor one. This paper examines the implications of a modified multi-factor-proportions model by measuring the simultaneous impact of a variety of factor intensities on the comparative advantage of all U.S. (trading) industries, classified and disaggregated by the 1958 input-output table. The novelty of the study lies in using a binary measure of comparative advantage. In order to by-pass several econometric difficulties, logit analysis is used to estimate the model. The principal conclusion of the paper is that capital-intensity has a significantly positive impact on the comparative advantage of U.S. manufacturing industries and, therefore, that the U.S. is, in fact, relatively capital-rich.     

Structural change in OECD comparative advantage

In the post-war period, the goods composition of trade in Organisation for Economic Cooperation and Development (OECD) countries has changed considerably. We analyze the evolution of comparative advantage using a detailed trade data set and a new analytical tool: the Harmonic Mass index (HM index), which enables us to identify periods of structural change. We then discuss which forces may be responsible for the main structural changes, which primarily took place in many OECD countries in the mid 1980s. The advantage of the HM analysis is that it indicates when structural breaks occur in history.     

Trade,development, and poverty-induced comparative advantage

This paper deals with the relation between trade and development when poverty affects individual decision making. We develop a two-sector model that links production and schooling decisions under poverty with standard neo-classical trade analyses. The decision to either work or acquire skills depends on households having reached subsistence levels of income, implying that the income level of a country becomes important in establishing comparative advantages and trade patterns. Trade liberalisation is always allocative efficient, but its timing is important for the speed by which countries industrialise. Our analysis supports the idea that there are instances that stalling trade liberalisation may serve industrial development.     

Embargo threat,learning and departure from comparative advantage

This paper extends the current analysis of trade embargo threats, initiated by Bhagwati and Srinivasan, Mayer, and others using general-equilibrium analysis, to a situation where there is the possibility of lowering the future cost of production of the potentially embargoed good as a result of learning-by-doing.     

Exports of developing countries: differentiation and comparative advantage

Differentiation among developing countries is a much-discussed phenomenon, mostly without being established in a consistent way. Differentiation implies both diversification of exports and differences between developing countries in this respect. It is the purpose of this article to measure differentiation among developing countries comprehensively and to relate this to changes in comparative advantage. Therefore, Theil's entropy index is applied to the manufactured exports of 100 developing countries over a period of 25 years, at the two- and three-digit level of the international-standard industrial classification. Both aspects of differentiation are confirmed. Manufacturing exports have, indeed, diversified for most developing countries, and some countries have been more successful than others. The latter group has increased its share in exports of developing countries by diversifying away from resource-intensive products toward more advanced products.     

Weak links in the chain of comparative advantage

This paper examines the proposition that trade in many commodities can be explained by a chain of comparative advantage. It is first shown, in a two-country, two-factor model, that trade accords with the ranking of goods by factor intensity if there are unequal factor prices, free trade, and only final goods. This result continues to hold if either trade impediments or intermediate products are introduced. However, if both are present, the chain proposition breaks down. Finally, with many countries, it is shown that trade impediments alone can invalidate the chain proposition.     

An antinomy in the theory of comparative advantage

This paper shows that the usual bilateral rule of comparing relative prices under autarky to determine the pattern of trade is not valid for the multicommodity world. In addition, equilibrium world price ratios need not fall between the corresponding price ranges under autarky. Such a paradox disappears under gross substitutability when the third commodity is a nontradeable. For the case of tradeables, an alternative bilateral rule to determine the pattern of trade is proposed. Since the classical constant cost case has been heavily discussed in the literature, we confine ourselves to the neoclassical case.     

Financial system,R&D intensity and comparative advantage

In this paper, we test whether financial system affects the export performance of R&D intensive industries. We consider four different dimensions of financial system: (1) financial development, (2) financial liberalization, (3) financial integration and (4) foreign banks. Our results show that financial development and financial integration increase exports relatively more in R&D intensive industries. These effects are highly robust. Financial liberalization and foreign banks do not have such effects. Our results also show that the positive effect of financial integration disappears when the quality of institutions and the level of financial development are low. To the best of our knowledge, this paper is the first study that examines the effects of different dimensions of financial system on exports through R&D channel.     

On the evolution of comparative advantage in matching models

This paper examines whether comparative advantage is the long-run outcome of an evolutionary process in the open economy. It formalizes the notion that natural selection eliminates inefficient firms and thus leads to stable and perhaps efficient patterns of world trade. Instead of assuming the existence of a Walrasian auctioneer, we study two simple matching processes that coordinate trade between firms. Our central result is that specialization according to comparative advantage, with the larger country possibly incompletely specialized, is the unique evolutionarily stable state of the world economy.     

The revealed comparative advantage of the east asian NICs

The spectacular export performance of the East Asian NICs is clearly indicated by their increasing shares of manufactured exports in the world markets. However, the conventional wisdom that the comparative advantage of industrialized countries such as Japan has systematically shifted to the NICs is challenged by the results from this study. A detailed analysis of the threedigit SITC product categories for manufactures indicates that NIC exports have not replaced Japan's in the U.S. market. The growth of manufactured exports from the NICs is moving along with the growth of Japan's exports in similar product categories but at different stages of the product cycle or of technology sophistication. Hence, the NICs, rather than replacing the exports from Japan, are merely supplying some complementary manufactured products to the industrialized market.     

Shifting comparative advantage,the nics,and the developing countries

It has been suggested that there have been shifts in comparative advantage for labor-intensive manufactures from the Newly Industrializing Countires (NICs) to other developing countries, permitting these latter states to export these products to the world market. An analysis of changes in exports for selected three-digit product categories for manufactures for sixteen countries from 1968 to 1976 and from 1976 to 1982, however, indicated that such shifts have not occurred. Many of the other developing countries that have expanded such exports have done so in the same product categories as the NICs, not different ones. In other cases, export gains of some developing countries were matched by losses by other developing states.     

Financial development,the choice of technology,and comparative advantage

In this general equilibrium model, banks and manufacturing firms engage in oligopolistic competition. A more advanced manufacturing technology has a higher fixed cost but a lower marginal cost of production. We show that manufacturing firms located in a country with a more efficient financial sector choose more advanced technologies and this country has a comparative advantage in the production of manufactured goods. Even though the foreign country has a less developed financial sector than the home country, the opening up of trade with the foreign country leads domestic manufacturing firms to adopt more advanced technologies. An increase in the level of efficiency in the financial sector of one country causes manufacturing firms in both countries to adopt more advanced technologies.     

Agriculture,innovational ability,and dynamic comparative advantage of LDCs

The goal of this paper is twofold: (1) to model a process of development based on the notion that the engine of growth is the generation of new ideas by skilled individuals, and (2) to explore the role of agricultural productivity growth in such a process. The key ingredients of our model are: preferences consistent with Engel's Law, and the asymmetry arising from there being a greater scope in industry than in agriculture for incremental innovation.
