Conventional two-country RBC models interpret countercyclical net exports as reflecting, in large part, the dynamics of capital. I show that, quantitatively, theoretical economies rely on counterfactual terms of trade effects: trade fluctuations, on the contrary, are driven primarily by...

This paper examines the business cycle properties of capital goods trade in open economies. Capital good imports and exports are twice as volatile as investment. Equipment trade is asymmetric in that small countries are net importers. Countercyclical trade balances are associated with...

Current account crises in emerging markets are characterized by large increases in interest rates, big drops in output, and large real currency depreciations. Current models of crisis with financial frictions do not generate very large movements in these variables. Recent work has shown that the...

This paper examines the importance of productivity shocks in accounting for salient features of U.S. economic developments during the second half of the 1990s, including the surge in investment spending, the substantial deterioration of the trade balance, and the modest decline in inflation. We...

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...

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...

The main goal of this paper is to measure the welfare costs of business cycles in a production economy in which the representative agent has low risk aversion and - at the same time - the equity premium and the co-movements of aggregate quantities and market returns are comparable to what...

This paper evaluates to what extent the introduction of firing costs can affect the aggregate dynamics of a neoclassical growth model with heterogeneous establishments. Similarly to the previous literature, firing costs are found to have large steady-state effects. However, they have no...

Shifts in the underlying growth rate of productivity, such as occurred in the 1970s and the 1990s, are relatively rare and difficult to identify in real time. In this paper, we document that economists' projections of trend productivity growth adjust gradually to shifts in trend growth. We find...
