A simple New-Keynesian model is set out with AS-AD graphical analysis. The model is consistent with modern central banking, which targets shortterm nominal interest rates instead of money supply aggregates. This simple framework enables us to analyze the economic impact of productivity or markup...

This paper studies the possibility of using the broad monetary aggregate M2 to target the quarterly rate of growth of nominal GDP. Our findings indicate that the Federal Reserve could probably guide M2 in a way that reduces not only the long-term average rate of inflation but also the variance...

"We examine how financial expansion and contraction cycles affect the broader economy through their impact on 8 real economic sectors in a panel of 28 countries over 1960-2005, paying particular attention to large, or sharp, contractions and magnifying and mitigating factors. Overall, the...

This paper characterizes the dynamic effects of shocks in government spending and taxes on economic activity in the United States in the post-war period. It does so by using a mixed structural VAR/event study approach. Identification is achieved by using institutional information about the tax...

Advanced economies feature complicated networks that connect households, firms, and regions. How do these structures affect the impact of fiscal policy and its optimal targeting? We study these questions in a model with input-output linkages, regional structure, and household heterogeneity in...

We explore a view of the crisis as a shock to investor sentiment that led to the collapse of a bubble or pyramid scheme in financial markets. We embed this view in a standard model of the financial accelerator and explore its empirical and policy implications. In particular, we show how the...

We review the evidence on the practice and effects of discretionary fiscal policy, particularly in the context of recent efforts to stimulate the economy, reaching two main conclusions. First, policy interventions have increased in this decade, pre-dating the 2009 stimulus. Second, despite a...

We introduce a solution technique for the study of discrete time stochastic models populated by long-lived agents. We introduce aggregate uncertainty and complete markets into a 'perpetual-youth' model of a kind first studied by Olivier Blanchard and we show that the pure-trade version of the...

We propose and apply a new approach for analyzing the effects of fiscal policy using vector autoregressions. Specifically, we use sign restrictions to identify a government revenue shock as well as a government spending shock, while controlling for a generic business cycle shock and a monetary...

Using a recursive empirical model of the real interest rate, GDP growth, and the primary government deficit in the U.S., I solve for the ergodic distribution of the debt/GDP ratio. If such a distribution exists, the government is satisfying its intertemporal budget constraint. One key finding is...
