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...

This paper studies the international propagation of sovereign debt default. We posit a two-country economy where capital constrained banks grant loans to firms and invest in bonds issued by the domestic and the foreign government. The model economy is calibrated to data from Europe, with the two...

Countries that are more engaged in production sharing exhibit higher bilateral manufacturing output correlations. We use data on trade flows between US multinationals and their affiliates as well as trade between the United States and Mexican maquiladoras to measure production-sharing trade and...

Following the rationale for regional redistribution programs described in the official documents of the European Union, this paper studies a very simple multi-country model built around two regions: a core and a periphery. Technological spill-overs link firms' productivity in each of the two...

traditionally seen only in terms of trade costs, many aspects of economic integration are more naturally viewed as lowering the cost of trading information rather than goods, i.e. as reducing the extent to which learning externalities are localised. Raising learning spillovers is stabilising, so...

This paper models the relationship between countries' distance from global economic activity, endogenous investments in education, and economic development. Firms in remote locations pay greater trade costs on both exports and intermediate imports, reducing the amount of value added left to...

The paper presents an intertemporal general equilibrium model with rationing in the product market, in which stationary sunspot equilibria are shown to exist, indicating the possibility of fluctuations in economic activity simply due to self-fulfilling variations in economic agents'...

This paper deals with the early stages of transformation of centrally-planned economies (CBEs) into market economies during which expectations playa key role. It focuses on the transitional phase during which the economy is not any more a CPE but has not yet become a market economy. During this...

A plot of expected returns versus betas obeys virtually no relation to an inefficient index portfolio's mean-variance location. If the index portfolio is inefficient, then the coefficients and R- squared from an ordinary-least-squares regression of expected returns on betas can equal essentially...

We introduce a technique called "precomputation of integrals" that makes it possible to compute conditional expectations in dynamic stochastic models in the initial stage of the solution procedure. This technique can be applied to any set of equations that contains conditional expectations, in...
