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....

This paper investigates whether OECD countries are facing secular stagnation. Secular stagnation is defined as a situation when policy interest rates bounded at zero fail to stimulate demand sufficiently, due to low or negative neutral real interest rates and low inflation, and when ensuing...

This chapter reviews and synthesizes our current understanding of the shocks that drive economic fluctuations. The chapter begins with an illustration of the problem of identifying macroeconomic shocks, followed by an overview of the many recent innovations for identifying shocks. It then...

We discuss the evolution in macroeconomic thought on the monetary policy transmission mechanism and present related empirical evidence. The core channels of policy transmission — the neoclassical links between short-term policy interest rates, other asset prices such as long-term interest...

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...

In recent years the euro area has shown less resilience to the negative and largely OECD-wide common shocks than the English-speaking countries, but most of the smaller euro area countries have fared better than the large ones. This paper reviews policy issues that are important in fostering a...

Estimates of the output gap ought to be a useful guide for macroeconomic policy, both for assessing inflationary pressures and fiscal sustainability, but their reliability has been called into question by the large revisions which they are often subject to, particularly around turning points....

What can history tell us about the relationship between the banking system, financial crises, the global economy, and economic performance? Evidence shows that in the advanced economies we live in a world that is more financialized than ever before as measured by importance of credit in the...

This paper develops a micro-founded general equilibrium model of the financial system composed of ultimate borrowers, ultimate lenders and financial intermediaries. The model is used to investigate the impact of uncertainty about the likelihood of governmental bailouts on leverage, interest...
