In this paper I analyze the relationships among investment, q, and cash flow in a tractable stochastic model in which marginal q and average q are identically equal. After analyzing the impact of changes in the distribution of the marginal operating profit of capital, I extend the model to...

It is widely acknowledged that many financial markets exhibit a considerably greater degree of kurtosis (and sometimes also skewness) than is consistent with the Geometric Brownian Motion model of Black and Scholes (1973). Among the many alternative models that have been proposed in this...

This paper studies the effects of marketing choice to firm growth. I assume that firm-level growth is the result of idiosyncratic productivity improvements with continuous arrival of new potential producers. A firm enters a market if it is profitable to incur the marginal cost to reach the first...

Managerial delegation is essential for firm growth. While firms in poor countries often shun outside managers and instead recruit among family members, the pattern is quite the opposite for firms in rich countries. In this paper, we ask whether these differences in managerial delegation have...

Market structure is determined by the entry and exit decisions of individual producers. These decisions are driven by expectations of future profits which, in turn, depend on the nature of competition within the market. In this paper we estimate a dynamic, structural model of entry and exit in...

Firm entry dynamics are an integral part of the propagation of financial shocks to the real economy. A VAR documents that adverse financial shocks in the U.S. postwar period are associated with a fall in new firm creation and a fall in firm equity values. We propose a DSGE model with endogenous...

We develop a regime-switching SVAR (structural vector autoregression) in which the monetary policy regime, chosen by the central bank responding to economic conditions, is endogenous and observable. There are two regimes, one of which is QE (quantitative easing). The model can incorporate the...

This paper studies the entry and exit of U.S. manufacturing plants over the business cycle and compares the results with those from a vintage capital model augmented to reproduce observed features of the plant life cycle. Looking at the entry and exit of plants provides new evidence supporting...
