This chapter surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three...

This paper surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy-making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three...

An independent currency and a flexible exchange rate generally helps a country in adjusting to macroeconomic shocks. But recently in many countries, interest rates have been pushed down close to the lower bound, limiting the ability of policy-makers to accommodate shocks, even in countries with...

Recent research has found that the dynamic properties of the New Keynesian model are unorthodox when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity and the size of the government purchase output multiplier is very large....

In contrast to industrialized countries, emerging market economies are characterized by pro- or acyclical monetary policies and high output volatility. This paper argues that those facts can be related to a long-run feature of the economy – namely, its institutional quality (IQL). The paper...

It is widely recognised that the "one-size-fits-all" monetary policy of the euro-zone is a potential problem. How much of a problem has not been much investigated. It is argued in this paper that it may result in the euro not being sustainable in the longer term without drastic changes to other...

This paper investigates the use of fiscal policy in response to a large negative aggregate demand shock which may push the global economy into a liquidity trap. Fiscal policy may be an effective tool to respond to a liquidity trap, but its international spillover effects may operate quite...

This paper identifies refinements to the macroeconomic framework that will help Brazil to achieve strong performance in a new environment in which population will age at a rapid pace, heavy reliance on oil resources will increase public revenue volatility and uncertainties regarding the external...

The economic impact from quantitative easing (QE) may be much less than assumed by the Federal Reserve. One focus is on the effectiveness of QE to stabilize a failing banking system, and the judgment here is largely positive. A second focus, especially in the US, is on evaluating subsequent...

This paper uses a New Keynesian framework to study the coordination of fiscal and monetary policies, in response to an inflation shock when the policymaker acts with commitment. We first show that, in the simplest New Keynesian model, fiscal policy plays no part in the optimal policy response,...
