This paper measures the mean, standard deviation, alpha and beta of venture capital investments, using a maximum likelihood estimate that corrects for selection bias. Since firms go public when they have achieved a good return, estimates that do not correct for selection bias are optimistic. The...

Conventional models of production under uncertainty specify that output is produced in fixed proportions across states of nature. I investigate a representation of technology that allows firms to transform output from one state to another. I allow the firm to choose the distribution of its...

The author surveys the statistical evidence on average stock return and the economic theories that try to explain it. The statistical evidence suggests a period of low returns, followed by a slow reversion to a high long-term average. However, that evidence is quite uncertain. Standard economics...

This paper measures the expected return, mean, standard deviation, alpha, and beta of venture capital investments. The focus of the paper is correcting for the selection bias that is the central obstacle in evaluating such investments. Therefore, valuations are observed only when a firm goes...

Uncertainty is a ubiquitous concern emphasized by policymakers. We study how uncertainty affects decision-making by the Federal Open Market Committee (FOMC). We distinguish between the notion of Fed-managed uncertainty vis-a-vis uncertainty that emanates from within the economy and which the Fed...
