We study a production economy with multiple sectors financed by issuing securities to agents who face capital constraints. Binding capital constraints propagate business cycles, and a reduction of the interest rate can increase the required return of high-haircut assets since it can increase the...

Since the 2008 global financial crisis, and after decades of relative neglect, the importance of the financial system and its episodic crises as drivers of macroeconomic outcomes has attracted fresh scrutiny from academics, policy makers, and practitioners. Theoretical advances are following a...

We examine global dynamics under learning in New Keynesian models with price level targeting that is subject to the zero lower bound. The role of forward guidance is analyzed under transparency about the policy rule. Properties of transparent and non-transparent regimes are compared to each...

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 reviews some of the most prominent asset price bubbles from the past 400 years and documents how central banks (or other institutions) reacted to those bubbles. The historical evidence suggests that the emergence of bubbles is often preceded or accompanied by an expansionary monetary...

This essay investigates the determinants of the growth performance of Africa. I start by illustrating a broader research agenda which accounts not only for basic economic and demographic factors, but also for the role of history and institutional development. After reporting results from...

We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal deficits and public debt have risen sharply in the wake of the financial crisis. While these developments make fiscal consolidation inevitable, there is considerable uncertainty about...

I argue that distinguishing between life expectancy at birth and life expectancy beyond the crucial early childhood years affects the relationship between life expectancy and schooling in a meaningful way. In particular, I show that while the change in life expectancy at birth between 1960 and...
