In recent years, a new form of risk has been recognized. This risk is the risk of crowded spaces. That is, how the saturation of a particular trading strategy can lead to a mis-measurement of the future expected returns and risks of the trading strategy. The primary focus of this risk has to do...

In this study, we show how both machine learning and alternative data can be successfully leveraged to improve and develop trading strategies. Starting from a trading strategy that harvests the EUR/USD volatility risk premium by selling one-week straddles every weekday, we present a machine...

Stock prices reflect firm performance and aggregate investor information about investment opportunities. We show that these dual roles are in tension: when prices are more informative about future investment, they are less effective at incentivizing managerial effort. Overall firm value need not...

The data-generating process of productivity growth includes both trend and business-cycle shocks, generating many counterfactuals for prices under full-information. In practice, agents cannot immediately distinguish between the two shocks, leading to ``rational confusion’’: each shock...

We examine how within-firm skill premia–wage differentials associated with jobs involving different skill requirements–vary both across firms and over time. Our firm-level results mirror patterns found in aggregate wage trends, except that we find them with regard to increases in firm size....

We present evidence that some firms pursue M&A activity with the objective of obtaining a larger workforce. Firms most likely to be acquired for their large labor force, firms with the largest ex ante employment, are associated with more positive post-merger employment outcomes. Moreover, we...

We present evidence that young employees are an important ingredient in the creation and growth of firms. Our results suggest that young employees possess attributes or skills, such as willingness to take risk or innovativeness, which make them relatively more valuable in young, high growth,...

We show that in the years following a large broad-based employee stock option (BBSO) grant, employee turnover falls at the granting firm. We find evidence consistent with a causal relation by exploiting unexpected changes in the value of unvested options. A large fraction of the reduction in...

Young firms disproportionately employ young workers, controlling for firm size, industry, geography and time. The same positive correlation between young firms and young employees holds when we look just at new hires. On average, young employees in young firms earn higher wages than young...
