Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country's share in world endowments and its share in producing firms: the so called home market effect (HME). While this result plays a key role in empirical testing,...

We derive closed-form solutions and sufficient statistics for inflation and GDP dynamics in multi-sector New Keynesian economies with arbitrary input-output linkages. Analytically, we decompose how production linkages (1) amplify the persistence of inflation and GDP responses to monetary and...

We develop a model of international trade between two symmetric countries that features inter-group inequality between entrepreneurs and workers, and also intra-group inequality within each of those two groups. Individuals in the economy are heterogeneous with respect to their entrepreneurial...

In this paper, we quantitatively assess the welfare implications of alternative public education spending rules. To this end, we employ a dynamic stochastic general equilibrium model in which human capital externalities and public education expenditures, financed by distorting taxes, enhance the...

The underlying model analyzes the first time foreign market entry decision of a representative investor who can choose between export and FDI. The model combines the proximity-concentration trade-off framework with the real option methodology and sheds light on the effects of productivity...

This paper examines how trade liberalization affects the innovation incentives of firms, and what this implies for industry productivity. For this purpose we develop a reciprocal dumping model of international trade with heterogeneous firms and endogenous R&D. Among the robust results that hold...
