This paper addresses the key determinants of merger failure, in particular the role of innovation (post-merger performance) and technology (ex-ante selection) when firms decide to separate. After a brief review of the existing literature we introduce a model of process innovation where merged...

Beginning in 1922, the rate of exit of U.S. tire producers increased sharply and the industry began a severe and protracted shakeout. Just five years earlier, the tire industry experienced a surge in entry that led to a rise of over 80% in the number of producers. We propose an explanation for...

While most economists believe that public scientific research fuels industry innovation and economic growth, systematic evidence supporting this relationship is surprisingly limited. In a recent study, Acemoglu and Linn (2004) identified market size as a significant driver of drug innovation in...

We derive equilibrium incentives to use comparative advertising that pushes up own brand perception and pulls down the brand image of targeted rivals. Data on content and spending for all TV advertisements in OTC analgesics enable us to construct matrices of dollar rival targeting and estimate...

There were no innovations in chemotherapy for myeloma patients during the period 1977-1997, but there have been several important innovations since 1997. We investigate the impact of recent chemotherapy innovation on the longevity of myeloma patients using both time-series U.S. data and...

We estimate a model of drug demand and supply that incorporates insurance, advertising, and competition between branded and generic drugs within and across therapeutic classes. We use data on antiulcer drugs from 1991 to 2010. Our simulations show generics and "me-too" drugs each increased...

For criminal violations of the Sherman Act, although guided by federal sentencing guidelines, U.S. Department of Justice has great latitude in recommending corporate cartel fines to the federal courts, and its recommendations are nearly always determinative. In this paper, we analyze the...

This paper investigates the impact of the digital camera on the demand for photographic film that are now facing the declining demand. Although few studies estimate demand function of declining industry, it is important in an oligopoly market to know how the slope of demand function changes when...

We investigate the effect of variations in the price of opium in Afghanistan on per capita dispensation of prescription opioids in the US. Quarterly county-level data for 2003-2016 indicate that reductions in opium prices significantly increase the quantity of opioids prescribed. The increase...
