How important are firm entry and exit in shaping aggregate dynamics? We address this question by characterizing the equilibrium allocation in Hopenhayn (1992)’s model of equilibrium industry dynamics, amended to allow for investment in physical capital and aggregate fluctuations. We find that...

We study the behaviour: of the average aggregate growth rate of an economy, driven by only small idiosyncratic total factor productivity shocks and where investment behaviour at the single plant level follows an (S,s) policy. We assume that in the case of investment (disinvestment) there are...

In U.S. data 1981–2012, unsecured firm credit moves procyclically and tends to lead GDP, while secured firm credit is acyclical; similarly, shocks to unsecured firm credit explain a far larger fraction of output fluctuations than shocks to secured credit. In this paper we develop a tractable...

This paper describes an equilibrium life-cycle model of housing where non-convex adjustment costs lead households to adjust their housing choice infrequently and by large amounts when they do so. In the cross-sectional dimension, the model matches the wealth distribution; the age profiles of...

This paper studies the relationship between volatility and long-run growth in a complete market economy with human capital accumulation and Epstein-Zin preferences. There is both cross-country and time-series evidence that volatility is associated with lower growth. Matching this evidence has...

In U.S. data 1981–2012, unsecured firm credit moves procyclically and tends to lead GDP, while secured firm credit is acyclical; similarly, shocks to unsecured firm credit explain a far larger fraction of output fluctuations than shocks to secured credit. In this paper we develop a...

Corporate managers tend to preserve cash with an expectation of a worse economy while spend cash to exercise growth opportunities with a favorable economic condition. We hypothesize that there exists a real option component of aggregate corporate cash holdings, serving both functions of...

We show that, in a large class of models, market frictions lead to predictable dynamic patterns of the acquisition and subsequent shedding of inputs by firms. The logic is as follows. During high demand and expansionary periods, firms that fail to have inputs (machinery, labor, space, credit) in...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...
