The Producer Price Index (PPI) for the United States suggests that semiconductor prices have barely been falling in recent years, a dramatic contrast to the rapid declines reported from the mid-1980s to the early 2000s. This slowdown in the rate of decline is puzzling in light of evidence that...

We propose an explanation for the rapid post-entry growth of surviving firms found in recent studies. At the core of our theory is the interaction between adjustment costs and learning by entering firms about their efficiency. We show that linear adjustment costs, i.e., proportional costs,...

This paper develops a framework for measuring digital services in the face of ongoing innovations in the delivery of content to consumers. We capture what Brynjolfsson and Saunders (2009) call "free goods" as the capital services generated by connected consumers' stocks of IT digital goods; this...

Competitive sorting models of the CEO labor market (e.g., Edmans, Gabaix and Landier (2009)) predict that differences in CEO productive abilities, or "talent", should be an important determinant of CEO pay. However, measuring CEO talent empirically represents a major challenge. In this paper, we...

We show that an activist's reputation is a critical determinant of the success of their campaigns. We model reputation as target managers' belief about the activist's willingness to initiate a proxy fight. Our model indicates reputation, rather than stake size, induces managers to settle without...

If managers maximize the payoffs of their shareholders rather than firm profits, then it may be anticompetitive for a shareholder to own competing firms. This is because a manager?s objective function may place weight on profits of competitors who are held by the same shareholder. Recent...

This paper examines the labor market for CEOs in the financial sector from 1988 to 2007, using a new hand-collected sample of 1,655 CEO successions. We document that there is a significant role of outside successions, as about one out of two successions involves an outside hire. In addition,...

We examine the effect of the social networks of bank directors on board gender diversity and compensation using a unique, newly compiled dataset over the 1999-2018 period. We find that within-board social networks are extensive, but there are significant differences in the size and gender...

Study of the impact of mergers and acquisitions (M&As) on productivity and market power has been complicated by the difficulty of separating these two effects. We use newly-developed techniques to separately estimate productivity and markups across a wide range of industries using detailed...

We assess the effects of geographic expansion on bank efficiency using cost and profit efficiency for over 7,000 U.S. banks, 1993-1998. We find that parent organizations exercise some control over the efficiency of their affiliates, although this control tends to dissipate with distance to the...
