The main goal of this article is to contribute to the theoretical analysis of international trade under imperfect competition using the Cournot oligopoly model with heterogeneous firms. In particular, our objective is to provide some insights into the role of cost asymmetry in studying the...

Firm-based approaches to international trade have revolutionized the study of trade politics. Corporate participation in political processes is costly, limiting access to large, productive, well-resourced, and often internationally engaged firms. This implies a pro-trade bias in corporate...

The objective of this paper is an ex-post evaluation of the European Union-Southern African Development Community Economic Partnership Agreement (EU-SADC EPA) stemming from changes in trade flows from the six members of the SADC (Botswana, Eswatini, Lesotho, Mozambique, Namibia, and South...

I study the role of firm heterogeneity for the transmission of unconventional monetary policy in the form of "credit policy" à la Gertler and Karadi (2011). To this end, I lay out a Two-Agent New-Keynesian model with financially constrained and unconstrained firms and a financial intermediary...

Since the emergence of information technology, the integrated circuit industry has been a major contributor to sustained economic expansion. This paper proposes a theoretical model premised on the pertinent theories of technological progress in late-mover countries and concludes that it is...

In this paper, a conceptual theoretical model is developed to better integrate various dimensions of the firms' decision to export. The model sheds light on the affirmations of the founding models of the 'new theory of international trade', in particular the role of productivity and sunk costs...

This paper studies the effects of the minimum wage on the life cycle of firms. We first build a tractable model where heterogeneous firms have labor market power, invest in innovation, and choose formal or informal sectors. The model predicts that a minimum wage hike not only shrinks young and...

Power laws in productivity and firm size are well documented empirical regularities. As they are upper right-tail phenomena, this paper shows that assuming asymptotic power functions for various model primitives (such as demand and firm heterogeneity) are sufficient for matching these...
