We study a banking model in which banks invest in a riskless asset and compete in both deposit and risky loan markets. The model predicts that as competition increases, both loans and assets increase; however, the effect on the loans-to-assets ratio is ambiguous. Similarly, as competition...

International macroeconomic policy coordination is generally considered to be made less likely—and less profitable—by the presence of uncertainty about how the economy works. The present paper provides a counter-example, in which increased uncertainty about portfolio preference of investors...

This paper documents the protracted process of shaping the rules governing oil operations in São Tomé and Príncipe. It analyzes the institutional framework for oil sector development, which applies Milton Friedman''s permanent income hypothesis to the management of oil resources. São Tomé...

Dollarization in Russia increased rapidly during the early 1990s, but failed to come down in the second half of the 1990s in spite of exchange rate stabilization. To explain this ""dollarization hysteresis,"" this paper develops a model in which network externalities in the demand for currency...

This paper analyzes exchange rate behavior in a model where consumers trade goods to diversify shocks to their income. A model with traded and nontraded goods is simulated in a multilateral context based upon historical output correlations for the period 1970–92. Simulation results indicate...

Evans (1991) has demonstrated that Blanchard’s (1985) finite-horizon model obeys approximate Ricardian equivalence. We show that this result is determined largely by an unrealistic assumption that labor income grows monotonically over a consumer’s entire lifetime. Introducing more realistic...

We argue that the U.S. personal saving rate's long stability (from the 1960s through the early 1980s), subsequent steady decline (1980s - 2007), and recent substantial increase (2008 - 2011) can all be interpreted using a parsimonious 'buffer stock' model of optimal consumption in the presence...
