This paper investigates the effects of government spending on the real exchange rate and the trade balance in the US using a new VAR identification procedure based on spending forecast revisions. I find that the real exchange rate appreciates and the trade balance deteriorates after a government...

We obtain the following results. (ii) Both supply and demand shocks are important sources of fluctuations; supply prevails for GDP, while demand prevails for employment and information. (ii) Policy matters: Both monetary and fiscal policy shocks have sizeable effects on output and prices, with...

We construct and calibrate a general equilibrium business cycle model with unemployment and precautionary saving. We compute the cost of business cycles and locate the optimum in a set of simple cyclical fiscal policies. Our economy exhibits productivity shocks, giving firms an incentive to hire...

The nineteenth century was a time of substantial changes in the patterns of economic growth. This was also a period of significant fluctuations in the structure of and allocation of political rights. Through successive franchise extensions, democracy expanded dramatically, giving birth to the...

This paper studies optimal monetary policy in a framework that explicitly accounts for policymakers uncertainty about the channels of transmission of oil prices into the economy. More specifically, I examine the robust response to the real price of oil that US monetary authorities would have...

An analysis of the performance of GDP, employment and other labor market variables following the troughs in postwar U.S. business cycles points to much slower recoveries in the three most recent episodes, but does not reveal any significant change over time in the relation between GDP and...

The Great Recession has challenged the adequacy of existing models to explain key macroeconomic data, and raised the concern that the models might be misspecified. This paper investigates the importance of misspecification in structural models using a novel approach to detect and identify the...

We study a dynamic economy where credit is limited by insufficient collateral and, as a result, investment and output are too low. In this environment, changes in investor sentiment or market expectations can give rise to credit bubbles, that is, expansions in credit that are backed not by...

Balance sheet recessions result from concentration of macroeconomic risks on the balance sheets of leveraged agents. In this paper, I argue that information dispersion about the future states of the economy combined with trading frictions in financial markets can explain why such concentration...

We document three changes in postwar US macroeconomic dynamics: (i) the procyclicality of labor productivity vanished, (ii) the relative volatility of employment rose, and (iii) the relative (and absolute) volatility of the real wage rose. We propose an explanation for all three changes that is...
