Regional liberalization sweeps the globe like wildfire while multilateral trade talks proceed at a glacial pace. Why are countries eager to liberalize regionally but reluctant to do so multilaterally? The answer of the GATT-is-dead school is that multilateralism is too cumbersome for...

Small transaction costs and uncertainty imply that optimal cross-currency interest rate speculation is marked by a first-order hysteresis band. Consequently uncovered interest parity does not hold and market-efficiency tests based on it are mis-specified. Indeed, measured prediction errors are a...

This paper presents a model in which long-run growth and industrial location are jointly endogenous. Specifically, it introduces Romer-Grossman-Helpman endogenous growth into Krugman’s core-periphery model with footloose labour. The paper focuses on stability of the symmetric equilibrium,...

The traditional explanation of resurgence regionalism nations rests on two pillars. Regionalism is: (i) due to frustration with the WTO process (thought to be too cumbersome for today’s trade issues); and (ii) due to the United States’ conversion from devoted multilateralist to ardent...

Recent events, historical evidence and geographical proximity suggest that the six EFTAns and twelve Central and East European countries (CEECs) are natural trading partners. This paper evaluates this suggestion by estimating the potential for EFTA-CEEC trade using the gravity model of Wang and...

Melitz (2003) demonstrates that greater trade openness raises industry productivity via a selection effect and via a production re-allocation effect. Our comment points out that the set-up assumed in the Melitz model displays a trade off between static and dynamic efficiency gains. That is,...

This paper explores the impact of trade on growth when firms are heterogeneous. Our findings can be viewed as relevant to the trade and growth literature on one hand and the heterogeneous-firms trade theory on the other. Our main finding – that freer trade is both anti-growth and welfare...

The 'core-periphery model' is vitiated by its assumption of static expectations. That is, migration (inter-regional or intersectoral) is the key to agglomeration, but migrants base their decision on current wage differences alone--even though migration predictably alters wages and workers are...

Recent trade models determine the equilibrium distribution of firm-level efficiency endogenously and show that freer trade shifts the distribution towards higher average productivity due to entry and exit of firms. These models ignore the possibility that freer trade also alters the firm-size...

This paper explores the impact of trade on growth when firms are heterogeneous. We find that greater openness produces anti-and pro-growth effects. The Melitz-model selection effects raises the expected cost of introducing a new variety and this tends to slow the rate of new-variety introduction...
