We generalize Krugman's (1979) 'new trade' model by allowing for an explicit production chain in which a range of tasks is performed sequentially by a number of specialized teams. We demonstrate that an increase in market size induces a deeper division of labor among these teams which leads to...

How large are optimal tariffs? What tariffs would prevail in a worldwide trade war? How costly would a breakdown of international trade policy cooperation be? And what is the scope for future multilateral trade negotiations? I address these and other questions using a unified framework which...

I develop a novel theory of GATT/WTO negotiations. This theory provides new answers to two prominent questions in the trade policy literature: first, what is the purpose of trade negotiations? And second, what is the role played by the fundamental GATT/WTO principles of reciprocity and...

What motivates regional governments to subsidize firm relocations and what are the implications of the subsidy competition among them? In this paper, I address these questions using a quantitative economic geography model which I calibrate to U.S. states. I show that states have strong...

Empirical evidence suggests that trade liberalization increases firm productivity. This paper offers a novel explanation for this finding. I develop a simple general equilibrium model of trade in which trade liberalization leads to outsourcing as firms focus on their core competencies in...

This paper presents a model of social learning about the suitability of local conditions for new business ventures and explores its implications for the microeconomic patterns of economic development. I show that: i) firms tend to ‘rush’ into business ventures with which other firms have had...

I highlight two advantages of adopting a "new trade" approach to trade negotiations. First, it allows for a view of trade negotiations in which producer interests play a prominent role. And second, it lends itself naturally to quantitative analyses of non-cooperative and cooperative trade...
