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 stumbling-bloc argument asserts that regionalism hinders MFN tariff cutting. If this was of first-order importance over previous decades, we should detect this in the levels of the tariffs. Using tariff line data for 23 large trading nations we find that MFN and PTA tariffs are complements,...

Based on theoretical distinctions suggested by the heterogeneous firms trade model and the quality heterogeneous firms trade model, we classify exports at the HS 6-digit level as being characterised by either quality or price competition. We find a high proportions of quality-competition goods...

This paper explores the growth implications of regional integration. From the theory, it identifies the ‘footprints’ that such growth should leave in the data. It then checks the data on the four poor EU nations for such footprints. Prima facie evidence for Ireland, Portugal and Spain...
