The classical Wage Fund (Capital or Credit) framework is integrated with the simplest text-book version of the Ricardian model of comparative advantage, generating a model that replicates important features of the neo-classical production theory involving capital and labour without neo-classical...

We illustrate a new source of comparative advantage that is generated by countries' different ability to adjust to technological change. Our model introduces substitution of workers in codifiable (routine) tasks with more efficient machines, a process extensively documented in the labor...

We present a unified dynamic framework to study the interconnections between international trade and business cycle models. We prove an aggregate equivalence between a competitive, representative firm model that has aggregate production externalities and dynamic trade models that feature...

We extend structural gravity models of bilateral trade flows to oligopolistic competition. We show that conventional gravity estimates do not only reflect trade costs but also market power. Our simple estimation procedure generalizes the standard gravity model and disentangles exogenous trade...

We develop a model of international trade with a monopsonistically competitive labour market in which firms employ skilled labour for headquarter tasks and unskilled workers to conduct a continuum of production tasks. Firms can enter foreign markets through exporting and through offshoring, and...

This paper analyzes the effects of credit frictions in a trade model where heterogeneous firms select both into exporting and into two types of external finance. In our framework, small producers face stronger credit frictions, pay a higher borrowing rate and rely on bank finance, whereas large...

This paper revisits the relationship between international trade and economic growth. We measure trade openness indices separately with respect to intermediate inputs and final goods and find that it is the former which turns out to be significant in explaining growth gains from trade. Using...

In this paper we revisit the influential theory of monopolistic competition and optimum product variety as developed by Dixit and Stiglitz (1977) with applications in international trade by Krugman (1979,1980), by modeling fixed and variable costs of production in terms of underlying use of...

This paper explores the role of wage fund as the basic source of credit, capital or finance in a dynamic Ricardian model, which consists of three classes of agents: the workers, the capitalist, and the producers of goods. We introduce and develop an elaborate dynamic wage fund model in the...

This paper examines the effects of a unilateral reform of the redistribution policy in an economy open to international trade. We set up a general equilibrium trade model with heterogeneous agents allowing for country asymmetries. We show that under international trade compared to autarky, a...
