In both, the presence of comparative advantage provides the scope for countries to gain from trade by specializing, and the pattern of that trade is explained by the pattern of comparative advantage. These strong results of the two-good model can be extended under certain circumstances to multiple goods… 
The general validity of comparative advantage in trade exchanges
In a recent article, Alan Deardorff (2005) analyses the strength of the comparative advantage’s principle. The present article’s purpose is to follow the generalization of some recent results
Revealed Comparative Advantage: What Is It Good For?
This paper applies a widely-used class of quantitative trade models to evaluate the usefulness of measures of revealed comparative advantage (RCA) in academic and policy analyses. I find that, while
Fragility of Comparative Advantage in Higher Dimensions: An Experimental Investigation
In this study, an experimental analysis of the fragility of the law of the comparative advantage in higher dimensions is performed. Noussair et al (1995) invoked a trading environment similar to the
Analysis of Production-Efficient Patterns of Specialization Allowing Intermediate Inputs: The Meaning of Shiozawa’s Model from the Viewpoint of Modern Economics
Two rare analyses on the theory of international economics with linear economics exist that have different lines of thought but similar model specifications. One is the analysis of
Analysis of Patterns of Specialization in the Ricardo Model with Joint Production
In this paper we analyze patterns of trade in a Ricardian trade model with joint production. First, we treat a simple two-country and two-good case to derive the necessary and sufficient conditions
Revisiting the Relevance of International Trade Theory
Probably one of the most controversial contributions to the literature of international trade theory was offered by the late social economist John Culbertson. In his view, low wage competition among
A New Construction of Ricardian Trade Theory—A Many-country, Many-commodity Case with Intermediate Goods and Choice of Production Techniques—
Ricardian trade theory is one of the most famous theories of economics but appears to have been little developed. Many attempts were made to extend the theory to multi-country, multi-commodity cases,
Inter and Intra Company Competition in the Age of Global Competition: A Micro and Macro Interpretation of Ricardian Trade Theory
The present paper reinterprets the comparative cost principle of David Ricardo in the light of the present global economy. Specifically, Ricardo’ s inequalities of comparative advantage, based on the
Diversification vs. specialization as alternative strategies for economic development: Can we settle a debate by looking at the empirical evidence?, ISID Working Paper 03/2012
Few ideas have been more vocally debated in the economic literature than that of diversification versus specialization as drivers of economic growth and development. Scores of scholars have written
Application of Jones’ Inequality to the N-Country, M-Good Ricardo–Graham Model
This paper discusses the results of the application of Jones' Inequality to the n-country, m-good Ricardo–Graham model. In the Jones' Inequality model, the number of countries is the same as the


Comparative Advantage, Trade, and Payments in a Ricardian Model with a Continuum of Goods -
This paper discusses Ricardian trade and payments theory in the case of a continuum of goods. The analysis thus extends the development of many-commodity, two-country comparative advantage analysis
The General Validity of the Law of Comparative Advantage
It is well known that the law of comparative advantage breaks down when applied to individual commodities or pairs of commodities in a many-commodity world. This paper shows that the law is
Theory Of International Trade
This book expounds trade theory emphasizing that a trading equilibrium is general rather than partial, and is often best modelled using dual or envelope functions. This yields a compact treatment of
Theory of International Trade. A Dual, General Equilibrium Approach
This book expounds trade theory emphasizing that a trading equilibrium is general rather than partial, and is often best modelled using dual or envelope functions. This yields a compact treatment of
Trade Costs
This paper surveys the measurement of trade costs --- what we know, and what we don't know but may usefully attempt to find out. Partial and incomplete data on direct measures of costs go together
