The volatility of US business cycles has declined during the last two decades. During the same period the financial structure of firms has become more volatile. In this paper we develop a model in which financial factors play a key role in generating economic fluctuations. Innovations in...

This study offers a single, consistent model that tracks the velocity of broad money (M2) since 1929, including the Great Depression, the global financial crisis, and the Great Recession. The model emphasizes the roles of changes in uncertainty and risk premia, financial innovation, and major...

This paper examines the problem of measuring the growth of a monetary aggregate in the presence of innovations in financial markets and changes in the relationship between individual assets and output. We propose constructing a monetary aggregate so that it is a good leading indicator of nominal...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

We develop a dynamic equilibrium model of complex asset markets with endogenous entry and exit in which the investment technology of investors with more expertise is subject to less asset-specific risk. The joint equilibrium distribution of financial expertise and wealth then determines risk...

Deleveraging from high debt can provoke deep recession with significant international side effects. The exchange rate of the deleveraging country will depreciate in the short run and appreciate in the long run. The real interest rate will fall by more than in the rest of the world. Bounds and...

While theoretical models consistently predict that government spending shocks should lead to appreciation of the domestic currency, empirical studies have been stubbornly finding depreciation. Using daily data on U.S. defense spending (announced and actual payments), we document that the dollar...

This paper presents a very simple model of the effects of flexible exchange rates in the transmission of business cycles. The starting point is the traditional "locomotive" effect, through exports and imports. Aside from this horizontal transmission, the intertemporal exchange rate model...

Currency depreciation in the 1930s is almost universally dismissed or condemned. It is credited with providing little if any stimulus for economic recovery in the depreciating countries and blamed for transmitting harmful beggar-thy-neighbor impulses to the rest of the world econonv. In this...

I revisit the potential costs and benefits for Sweden of joining the Economic and Monetary Union (EMU) of the European Union. I first show that the Swedish business cycle since the mid-1990s has been closely correlated with the Euro area economies, suggesting that common shocks have been an...
