We show that the welfare of a country's infinitely-lived representative consumer is summarized, to a first order, by total factor productivity (TFP) and by the capital stock per capita. These variables suffice to calculate welfare changes within a country, as well as welfare differences across...

We prove that in a closed economy without distortionary taxation, the welfare of a representative consumer is summarized to a first order by the current and expected future values of the Solow productivity residual in level and by the initial endowment of capital. The equivalence holds if the...

We build a two country asymmetric DSGE model with two features: (i) endogenous and slow diffusion of technologies from the developed to the developing country, and (ii) adjustment costs to investment flows. We calibrate the model to match the Mexico-U.S. trade and FDI flows. The model is able to...

Using a large sample of developing and industrialized economies during 1970-1999, this paper explores whether the choice of exchange rate regime affects the sensitivity of local interest rates to international interest rates. In most cases, we cannot reject full transmission of international...

The corners hypothesis holds that intermediate exchange rate regimes are vanishing, or should be. Surprisingly for a new conventional wisdom, this hypothesis so far lacks analytic foundations. In part, the generalization is overdone. We nevertheless offer one possible theoretical rationale, a...

How do countries hold their financial wealth? We construct a new database of countries' claims on capital located at home and abroad, and international borrowing and lending, covering 68 countries from 1966 to 1997. We find that a small amount of capital flows from rich countries to poor...

Hard pegs, such as currency boards, intend to reduce or even eliminate currency risk. This paper investigates the patterns and determinants of the currency risk premium in two currency boards -- Argentina and Hong Kong. Despite the presumed rigidity of currency boards, the currency premium is...
