In this paper we construct a Ricardian model of trade in vertically-differentiated products between a developing country and the (developed) rest of the world. Despite labour being the only factor of production in this model, tariffs (in addition to income taxes) have distributional consequences...

We consider progressive geographical expansion of free trade zones within countries as a form of trade liberalization and compare observationally equivalent liberalization involving changes in the coverage of a free trade zone for a fixed tariff rate, and tariff reductions applying to all trade...

This paper reconsiders the welfare effects of "tariff jumping" direct investment if mobile capital is subjected to taxation. In contrast to the conventional wisdom, the receiving country may in this case gain from the incremental inflow of capital, as this diverts tax revenues from the rest of...

Should the government run fiscal deficits in response to an adverse external shock that warrants transfer of resuorces from production of non-traded to traded goods? This paper considers nprmative fiscal policy implications of sectoral adjustment costs in a two-sector model with overlapping...

In this paper we examine the empirical relevance of three prominent endogenous protection models. Is protection for sale, or do altruistic policy makers worry about political support? We find strong evidence that protection is indeed "for sale". The important new result is, however, that not...

This paper surveys recent advances in the monetary transmission mechanism (MTM). In particular, while laying out the functioning of the separate channels in the MTM, special attention is paid to exploring possible interrelations between different channels through which they may amplify or...

We construct an overlapping generations model for the small open economy which incorporates a realistic description of the mortality process. Agents engage in educational activities at the start of life and thus create human capital to be used later on in life for production purposes. Depending...

This paper analyzes the effects of fiscal policy in an open economy. We extend the savers-spenders theory of Mankiw (2000) to a small open economy with endogenous labor supply. We first show how the Dornbusch (1983) consumption-based real interest rate for open economies is modified when labor...

When capital is perfectly mobile across countries and labour is fixed, a source-based tax on capital both reduces and redistributes world income. We show that under plausible circumstances there always exists a country that benefits from introducing such a tax.

I study a model of geopolitical organization endogenizing the size of nations, of their public spending and of their degree of openness. The optimal geography may not be a stable equilibrium and the Alesina-Spolaore bias toward too many nations tends to be confirmed. However, multiple equilibria...
