Using data on elderly individuals and couples, we estimate a collective model of household consumption of a variety of goods, showing how resources are shared between husband and wife, and how this allocation is affected by retirement and health status. We identify the extent to which shared...

We show how to relate the welfare of a country's infinitely-lived representative consumer to observable aggregate data. To a first order, welfare is summarized by total factor productivity and by the capital stock per capita. These variables suffice to calculate welfare changes within a country,...

I develop a tractable, two-country, real model of macroeconomic interdependence with a role for net foreign asset dynamics. Absence of Ricardian equivalence in an overlapping generations structure ensures existence of a well-defined, endogenously determined, steady-state, international...

We compare the performance of a currency board arrangement, inflation targeting, and dollarization in a small open, developing economy with liberalized capital account. We focus explicitly on the transmission of shocks to currency and country risk premia in international financial markets and on...

We prove that the change in welfare of a representative consumer is summarized by the current and expected future values of the standard Solow productivity residual. The equivalence holds if the representative household maximizes utility while taking prices parametrically. This result justifies...

I compare the performance of alternative monetary rules for Canada using an open economy model under incomplete markets. Different rules generate different paths for the markup and the terms of trade. A comparison of welfare levels suggests that flexible inflation targeting, the Bank of...
