This essay discusses the effect of technical change on wage inequality. I argue that the behavior of wages and returns to schooling indicates that technical change has been skill-biased during the past sixty years. Furthermore, the recent increase in inequality is most likely due to an...

To study the short-run and long-run implications on wage inequality, we introduce directed technical change into a Ricardian model of offshoring. A unique final good is produced by combining a skilled and an unskilled product, each produced from a continuum of intermediates (tasks). Some of...

Crowdsourcing is an emerging technology where innovation and production are sourced out to the public through an open call. At the center of crowdsourcing is a resource allocation problem: there is an abundance of workers but a scarcity of high skills, and an easy task assigned to a high-skill...

This paper offers a model where firms decide what types of jobs to create and then search for suitable workers. When there are few skilled workers and the productivity gap between the skilled and the unskilled is small, firms create a single type of job and recruit all workers. An increase in...

I construct a neoclassical, Q-theoretical foundation for time-varying expected returns in connection with corporate policies and events. Under certain conditions, stock return equals investment return, which is directly tied with firm characteristics. This single equation is shown analytically...

Feedback from stock prices to cash flows occurs because information revealed by firms' stock prices influences the actions of competitors. We explore the implications of feedback within a noisy rational expectations setting with incumbent publicly traded firms and privately held new entrants. In...

We study the interactions between the stock market and the labor market. When aggregate risk premiums are time-varying, predictive variables for market excess returns should forecast long-horizon growth in the marginal benefit of hiring and thereby long-horizon aggregate employment growth....

We construct accounting-based costs of equity for dollar neutral long-short trading strategies formed on a comprehensive list of anomaly variables. These variables include book-to-market, size, composite issuance, net stock issues, abnormal investment, asset growth, investment-to-assets,...

We use yield spreads to construct ex-ante returns on corporate securities, and then use the ex-ante returns in asset pricing assets. Differently from the standard approach, our tests do not use ex-post average returns as a proxy for expected returns. We find that the market beta plays a much...

Optimal investment of firms implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of...
