This study shows that in a standard one-sector neoclassical growth model, in which money is introduced with a cash-in-advance constraint, zero nominal interest rates are optimal. Milton Friedman argued in 1969 that zero nominal rates are necessary for efficient resource allocation. This study shows that they are not only necessary but sufficient. The study also characterizes the monetary polici...

We examine the time-varying causal link between monetary policies and macroeconomy, macroprudential financial stability in China. find that expansionary policy leads to output growth, tightening price stability, quantitative or expanding price-based is effective maintaining stability. In response stagnation deflation, central bank implements an policy. To prevent turbulence, pursues a tight add...

Although there is a substantial body of literature on macroeconomic policies in Latin America, the role of fiscal and monetary policies as tools to stabilize the business cycle has not received much attention. This is understandable in light of the fact that during the last thirty years, both fiscal and monetary policies were responsible, to a large degree, for the region’s history of macroecon...

Early critics of the euro’s design pointed to the disruptive potential — both political and economic — of country-specific shocks in a monetary union that is a far cry from an optimal currency area. The euro crisis has confirmed the risks associated with a ‘one-size-fits-all’ monetary policy, decentralized financial supervision, and inadequate fiscal backstops. This article examines how the act...

A simple model of monetary/labor search is constructed to exposit and evaluate Keynesian ideas. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. With either fixed nominal wages and prices, or indeterminacy in rates of exchange, the optimal policies we explore seem ...

This paper investigates the dynamic effects of monetary and fiscal policy in a monetary union, which is characterized by asymmetric interest rate transmission. This asymmetry gives rise to intertemporal reversals in the relative effectiveness of policy on member country outputs. The direction and the number of these reversals depend on whether policies are unanticipated or anticipated. We also ...

I formulate a search-based asset-pricing model where equity shares and fiat money can be used as means of payment. I characterize a family of optimal stochastic monetary policies. Every policy in this family implements Friedman’s prescription of zero nominal interest rates. Under an optimal policy, equity prices and returns are independent of monetary considerations. I also study a perturbation...

Determining how monetary policy makers react to changes in key economic variables has been of major interest to monetary economists. Estimates of monetary policy rules (reaction functions) are a widely used method for doing this. Behavior differs under different policy regimes, as in rule-based systems or chronic inflation. In practice, estimates of instrument rules have been used to descri...

In the past decade there have been important changes in the design and conduct of monetary policy around the world. Movements in global capital during the late 1990s and the greater emphasis on price stability forced many countries to abandon fixed exchange rate regimes and to design institutions and monetary policies to achieve credibility in the goal of lowering inflation. Such recent deve lo...
