Are there optimal multiple reserve requirements?
A number of developing countries have adopted deficit-finance regimes involving multiple reserve requirements. One question the previous literature on this phenomenon has not addressed is whether multiple-reserves regimes can improve on regimes involving single-currency-reserve requirements if the policy settings of the latter regimes are assumed to be chosen optimally. We find that a "conventional" multiple-reserves regime--a regime with positive nominal rates on reservable bonds--cannot Pareto-improve an optimal single-currency-regime but can, in some cases, increase social welfare over ...

On government credit programs
Credit rationing is a common feature of most developing economies. In response to it, the governments of these countries often operate extensive credit programs and lend, either directly or indirectly, to the private sector. We analyze the macroeconomic consequences of a typical government credit program in a small open economy. We show that such programs increase long-run production if the economy is in a development trap and that such programs often lead to endogenously arising aggregate volatility. On the other hand, they may eliminate certain indeterminacies created by endogenous credit ...

Stability of steady states in a model of pleasant monetarist arithmetic
In this paper the authors study the stability properties of the alternative steady-state equilibria that arise in a neoclassical production model that delivers pleasant monetarist arithmetic. They show that if the government?s monetary policy rule involves a fixed money supply growth rate, then ?pleasant arithmetic? steady states?steady states from which a permanent increase in the money growth and inflation rates is associated with a permanent decrease in the real interest rate and a permanent increase in the level of output?are dynamically stable.

Fully funded social security: Now you see it, now you don't?
Governments of countries around the world, including the United States, are considering implementing social security reform programs. In most cases, one of the principal goals of the reform program is to convert a pay-as-you-go social security system into a fully funded system. Most economists believe that the long-run macroeconomic benefits of a successful transition to a fully funded system are likely to be large relative to the benefits from social security reforms of other types. ; The authors of this article describe the basic differences between pay-as-you-go and fully funded systems ...

An endogenous growth model of money, banking, and financial repression
In this paper, we develop an endogenous growth model with financial intermediation to examine the effects of financial repression on growth, inflation, and welfare. By limiting the liquidity provision, binding reserve requirements always suppress economic growth while their effect on inflation is a function, among other things, of the degree of repression. For example, contrary to previous claims, if financial repression is severe enough so that an informal financial sector emerges, liberalization is inflationary. Notwithstanding, liberalization in these cases is always welfare improving. ...
