Power Laws in Firm Size and Openness to Trade


Book Description

Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in absolute value than the power law exponent among non-exporting rms. We use a dataset of French firms to demonstrate that this prediction is strongly supported by the data. While estimates of power law exponents have been used to pin down parameters in theoretical and quantitative models, our analysis implies that the existing estimates are systematically lower than the true values. We propose two simple ways of estimating power law parameters that take explicit account of exporting behavior.

Free Trade and Absolute and Comparative Advantage


Book Description

This thesis deals with two theories of international trade: the theory of comparative advantage, which is connected to the name David Ricardo and is dominating current trade theory, and Adam Smith’s theory of absolute advantage. Both theories are compared and their assumptions are scrutinised. The former theory is rejected on theoretical and empirical grounds in favour of the latter. On the basis of the theory of absolute advantage, developments of free international trade are examined, whereby the focus is on trade between industrial and underdeveloped countries. The main conclusions are that trade patterns are determined by absolute production cost advantages and that the gap between developed and poor countries is not reduced but rather increased by free trade.




Comparative Advantage and Heterogeneous Firms


Book Description

This paper examines how country, industry and firm characteristics interact in general equilibrium to determine nations' responses to trade liberalization. When firms possess heterogeneous productivity, countries differ in relative factor abundance and industries vary in factor intensity, falling trade costs induce reallocations of resources both within and across industries and countries. These reallocations generate substantial job turnover in all sectors, spur relatively more creative destruction in comparative advantage industries than comparative disadvantage industries, and magnify ex ante comparative advantage to create additional welfare gains from trade. The relative ascendance of high-productivity firms within industries boosts aggregate productivity and drives down consumer prices. In contrast with the neoclassical model, these price declines dampen and can even reverse the real wage losses of scarce factors as countries liberalize.
