This paper studies the domestic and international effects of the transition to an interstate banking system implemented by the U.S. since the late 1970s in a dynamic, stochastic, general equilibrium model with endogenous producer entry. Interstate banking reduces the degree of local monopoly...

This paper presents a single error-correction analysis of German total, euro-area (intra) and non-euro-area (extra) import demand for the 1980-2004 period and the more recent 1993-2004 period. German import demand is mainly driven by domestic demand and foreign demand for German goods; by...

We study Ramsey-optimal fiscal policy in an economy in which product varieties are the result of forward-looking investment decisions by firms. There are two main results. First, depending on the particular form of variety aggregation in preferences, firms' dividend payments may be either...

I characterize cyclical fluctuations in the cross-sectional dispersion of firm-level productivity in the U.S. manufacturing sector. Using the estimated dispersion, or "risk," stochastic process as an input to a baseline DSGE financial accelerator model, I assess how well the model reproduces...

Is time-varying firm-level uncertainty a major cause or amplifier of the business cycle? This paper investigates this question in the context of a heterogeneousfirm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

Using a unique German firm-level data set, this paper is the first to jointly study the cyclical properties of the cross-sections of firm-level real value added and Solow residual innovations, as well as capital and employment adjustment. We find two new business cycle facts: 1) The...

International Macroeconomics has long sought an explanation for current account fluctuations that matches the data. The approaches have typically focused on better models and new macroeconomic variables. We demonstrate the limitations of this approach by showing that idiosyncratic shocks are an...

International financial integration has greatly increased the scope for changes in a country's net foreign asset position through the "valuation channel" of external adjustment, namely capital gains and losses on the country's external assets and liabilities. We examine this valuation channel...
