The returns to hedge funds and other alternative investments are often highly serially correlated in sharp contrast to the returns of more traditional investment vehicles such as long-only equity portfolios and mutual funds. In this paper, we explore several sources of such serial correlation...

Using a large sample of institutional investors' private equity investments in venture and buyout funds, we estimate the extent to which investors' skill affects returns from private equity investments. We first consider whether investors have differential skill by comparing the distribution of...

We empirically analyze the nature of returns to scale in active mutual fund management. We find strong evidence of decreasing returns at the industry level: As the size of the active mutual fund industry increases, a fund's ability to outperform passive benchmarks declines. At the fund level,...

This paper studies how hedge fund activism reshapes corporate innovation. Firms targeted by hedge fund activists experience an improvement in innovation efficiency during the five-year period following the intervention. Despite a tightening in R&D expenditures, target firms experience increases...

Much work in finance is devoted to identifying characteristics of firms, such as measures of fundamentals and beliefs, that explain differences in asset prices and expected returns. We develop a framework to quantitatively trace the connection between valuations, expected returns, and...

On the basis of a country*industry unbalanced panel data sample for 14 OECD countries and 18 industries covering the years 1988 to 2007, this study proposes an econometric investigation of the effects of the OECD Employment Protection Legislation (EPL) indicator on capital intensity for four...

Over the past 15 years, labor-quality growth has been very strong--defying nearly all earlier projections--and has added around 0.5 percentage points to an otherwise modest U.S. productivity picture. Going forward, labor quality is likely to add considerably less and may even be a drag on...

The Occupational Requirements Survey (ORS) is a new survey at the Bureau of Labor Statistics which collects data on the educational, cognitive, and physical requirements of jobs, as well as the environmental conditions in which the work is performed. Using pre-production data, we provide...

We develop a theory of career paths and earnings in an economy in which agents organize in production hierarchies. Agents climb these organizational hierarchies as they learn stochastically from other individuals. Earnings grow over time as agents acquire knowledge and occupy positions with...
