Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

This paper proposes a model where heterogeneous firms choose whether to undertake R&D or not. Innovative firms are more productive, have larger investment opportunities and lower own funds for necessary tangible continuation investments than non-innovating firms. As a result, they are...

We consider the optimal education policies of a small economy whose government has a limited budget. Initially, the economy is closed and the government chooses its education policy to maximize welfare under autarky. Then the economy trades with the rest of the world. Lastly, the government...

We present a two-good, two-country overlapping generations model where emissions arise from production and each country has a domestic emission permit system. When one country unilaterally reduces her cap on emissions, her output available for domestic and foreign consumption diminishes more...

Worker movements played a crucial role in making workplaces safer. Workplace safety is costly for firms but increases labour supply. A laissez-faire approach leaving safety of workplaces unknown is suboptimal. Safety standards set by better-informed trade unions are output and welfare...

We study the role of endogenous healthcare choices by households to extend their expected lifetimes on economic growth and welfare in a decentralized overlapping generations economy with the realistic feature that households' savings are held in annuities. We characterize healthcare spending in...

We study the global diffusion of culture through multinationals, focusing on gender norms. Using data on manufacturing firms in China over 2004-2007, we find that foreign affiliates from countries with a more gender-equal culture tend to employ proportionally more women and appoint female...

The emergence of the Asian tiger countries and the participation of the ex-communist countries in world trade has reduced the equilibrium price of labor in western Europe and elsewhere. However, the actual price of labor hardly reacts, because the welfare state's minimum replacement incomes are...

We analyze the role of imitation and innovation in promoting technological progress in new members of European Union: the Czech Republic, Hungary, Poland and Slovakia. The two modes of technological development - innovation and imitation - are distinguished from one another by identifying the...

Theoretical discussion on compensating mechanisms involving the Pareto criterion that address inequality rather than absolute welfare is non-existent in trade literature. In a simple HOS model we consider tax-transfer policies that keep the pre-trade degree of inequality unchanged between...
