This paper conducts a theoretical comparison of the potential effectiveness, in terms of money stock controllability, of interest rate and reserve instruments. Whereas previous studies have been basically static, the present analysis is carried out in the context of a dynamic macroeconomic model...

Empirical studies suggest that fluctuations in the level and volatility of the world interest rate (as measured by the US treasury bill rate) affect sovereign spreads in emerging economies. We incorporate an estimated time-varying process for the world interest rate (with both level and...

Using an optimizing model we derive the optimal monetary and exchange rate policy for a small stochastic open economy with imperfect competition and short run price rigidity. The optimal monetary policy has an exact closed-form solution and is obtained using the utility function of the...

We show that the partial response of loan rates to interest rate changes, referred to in the bank lending literature as “stickiness,” is a feature of perfect capital markets. No-arbitrage models of credit risk are able to replicate empirical interest rate sensitivities. However, the...

We study a novel policy tool—interest rate uncertainty—that can be used to discourage inefficient capital inflows and to adjust the composition of external accounts between short-term securities and foreign direct investment (FDI). We identify the trade-offs faced in navigating between...

There is widespread feeling that current deficits, in Europe and the U.S.,may hurt rather than help the recovery. This paper examines some of the issues involved, through a sequence of three models.The first model focuses on sustainability and characterizes its determinants. It suggests that the...

In recent years, central banks have increasingly turned to “forward guidance” as a central tool of monetary policy, especially as interest rates around the world have hit the zero lower bound. Standard monetary models imply that far future forward guidance is extremely powerful: promises...
