Purchases and sales of operating assets by firms generated $162 billion for shareholders over the past 20 years. This contrasts sharply with the evidence on mergers. This paper characterizes the behavior of value-maximizing firms, which may grow organically, purchase existing assets or sell...

A simple efficiency-based view states that acquisitions shift assets to more productive owners. This implies that expected returns from acquisitions increase with transaction value. We propose using the sensitivity of abnormal returns to scaled transaction value as a measure of efficiency gains....

We use data on U.S. insurance companies to examine the validity of the conglomeration hypothesis versus the strategic focus hypothesis for financial institutions. We distinguish between the hypotheses using profit scope economies, which measures the relative efficiency of joint versus...

The threat of entry is an important factor in the evaluation of the potential competitive effects of proposed mergers and acquisitions. In the evaluation of proposed bank mergers, a high probability of entry, or strong potential competition, is often found to mitigate the potential...

An extensive literature has investigated the effect of market structure on innovation. A persistent concern is that market structure may be endogenous to innovation. Firms may choose to merge so as to capture information spillovers or they may choose to merge so as to dampen competition in...

How much of aggregate employment fluctuations is due to plants destroying and then recreating the same jobs over the cycle and how much is due to some plants permanently destroying jobs in a recession and other plants permanently creating jobs in an expansion? This paper decomposes plant level...

We examine the ability of auto industry stock returns to forecast quarterly changes in the growth rates of real GDP, consumption, and investment. We find that auto stock returns are superior to aggregate stock market returns in predicting growth rates of GDP and various forms of consumption. The...

This paper establishes the cyclical properties of a novel measure of worker reallocation: long-distance migration rates within the U.S. This internal migration offers a bird's eye view of worker reallocation in the economy, as long-distance migrants often change jobs or employment status. We...
