I study a dynamic economy featuring adverse selection in asset markets. Borrowing-constrained entrepreneurs sell past projects to finance new investment, but asymmetric information creates a lemons problem. I show that this friction is equivalent to a tax on financial transactions. The implicit...

This paper focuses on the importance of equity markets in facilitating the exit of entrepreneurs investing in technology. Entrepreneurs' willingness to invest and aggregate output is affected in two opposite ways. First, uncertainty about equity price or lack of market liquidity discourages...

Several impatient investors with private costs <em>C_i</em> face an indivisible irreversible investment opportunity whose value <em>V</em> is governed by geometric Brownian motion. The first investor <em>i</em> to seize the opportunity receives the entire payoff, <em>V-C_i</em>. We characterize the symmetric Bayesian Nash...

Entrepreneurs bear substantial risk, but empirical evidence shows no sign of a positive premium. This paper develops a theory of endogenous entrepreneurial risk taking that explains why self-financed entrepreneurs may find it optimal to invest in risky projects offering no risk premium....

The cross-sectional dispersion of firm-level investment rates is procyclical. This makes investment rates different from productivity, output, and employment growth, which have countercyclical dispersions. A calibrated heterogeneous-firm business cycle model with nonconvex capital adjustment...

We examine investment behavior when firms face costs in the access to external funds. We find that despite the existence of liquidity constraints, standard investment regressions predict that cash flow is an important determinant of investment only if one ignores q. Conversely, we also obtain...

The intertemporal elasticity of investment for long-lived capital goods is nearly infinite. Consequently, investment prices should fully reflect temporary tax subsidies, regardless of the investment supply elasticity. Since prices move one-for-one with the subsidy, elasticities can be inferred...
