In an infinite-horizon model with Marshallian time preferences, foreign aid, foreign borrowing, and domestic capital accumulation, this paper reexamines the effects of foreign aid on domestic capital accumulation and foreign borrowing. Comparative static analysis shows that a permanent increase...

This paper considers foreign asset holdings and macroeconomic policies in a finite-horizon model with real balances and foreign asset holdings in a small open economy. Both the long- and short-run effects of these macroeconomic policies on the economy are reexamined. The main results stand in...

This paper studies the risk‐free rate in an overlapping generations economy with bequests. It is shown that the risk‐free rate depends on risk aversion, the elasticity of intertemporal substitution, the share of wealth invested in human wealth, life expectancy, and the preference for...
