Democratic countries with substantial inequality and where people believe that success depends on connections and luck induce political support for high tax rates and generous welfare states. Traditional wisdom is that such policies harm the economy, but there is not much evidence that countries...

We return to a familiar topic in international trade, comparative advantage, introducing it into a model of economic geography. We provide a clear counterexample to the familiar result that trade liberalization leads to increased industrial concentration. Instead, lower trade costs may lead to a...

In models of economic geography, plant-level scale economies and trade costs create incentives for spatial agglomeration of production into a manufacturing core and agricultural periphery, creating regional income differentials. We examine tax competition between national governments to...

This paper evaluates the global welfare impact of observed levels of migration using a quantitative multi-sector model of the world economy calibrated to aggregate and firm-level data. Our framework features cross-country labor productivity difference, international trade, remittances, and a...

The paper studies the role of international implications after EU enlargement. Based on a formal model with migration costs for both capital and labor, it predicts a two-sided migration from the new to the old EU countries which is later reversed. As the migration pattern chosen by market forces...

We examine the consequences of increased economic integration between nations within a region. We adopt Krugman’s economic-geography model in which demand linkages can generate agglomeration of manufacturing activity. Manufacturing labour is assumed to be imperfectly mobile between countries....

While barriers to trade in most goods and some services including capital flows have been reduced considerably over the past two decades, many remain. Such policies harm most the economies imposing them, but the worst of the merchandise barriers (in agriculture and textiles) are particularly...

This Paper analyses an overlapping generation model of public good provision under repeated voting. The public good is financed through age-dependent taxation that distorts human capital investment. Taxes redistribute income both across different skill groups and across generations. We contrast...

The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on unemployment; and the political difficulties in implementing more extensive reform programmes. We argue that the heart of...
