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...

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 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,...

This paper studies a simple New-Keynesian model of fiscal and monetary policy coordination when the policymaker acts under commitment. With a New Keynesian Phillips curve it is optimal to control inflation only through the use of monetary policy. But, when price-setters use a Steinsson (2003)...

This paper is about the size of fiscal multipliers and the sources of recovery from the Great Depression. Its contributions begin with a new quarterly data set for the interwar period that allows development of a VAR model of the U. S. economy over the period 1920-41. The quarterly data...

After a brief review of the main differences between New and Old Keynesian economics from the 1960s this paper focuses on a tension between traditional sluggish measures of potential output commonly used by policy-makers and the New Keynesian (NK) notion of this variable which conceptualizes it...

The paper discusses some fundamental problems in monetary economics associated with the determination and role of the numéraire. The issues are introduced by formalising a proposal, attributed to Eisler, to remove the zero lower bound on nominal interest rates by unbundling the numéraire and...

The global financial crisis of 2007-09 has led to an intensive research program analyzing a wide range of issues related to financial crises. This paper presents a summary of a forthcoming book, Financial Crises: Causes, Consequences, and Policy Responses, that includes 19 contributions...

This paper aims to provide a rigorous analysis of Milton Friedman’s famous parable of the ‘helicopter’ drop of money. A helicopter drop of money is a permanent/irreversible increase in the nominal stock of fiat base money with a zero nominal interest rate, which respects the intertemporal...
