• Cory Capps, Dennis Carlton, Guy David (Under Review), Antitrust Treatment of Nonprofits: Should Hospitals Receive Special Care?. Abstract

  Nonprofit hospitals receive favorable tax treatment in exchange for providing socially beneficial activities. Extending this rationale suggests that nonprofit hospital mergers should be evaluated differently than mergers of for-profit hospitals because suppression of competition may also allow nonprofits to cross-subsidize care for the poor. Using detailed California data, we find no evidence that nonprofit hospitals are more likely than for-profit hospitals to provide more charity care or offer unprofitable services in response to an increase in market power. Therefore, we find no empirical justification for different antitrust standards for nonprofit hospitals, as some courts have suggested.

• Guy David and Sara Markowitz (Under Review), Side Effects of Competition: the Role of Advertising and Promotion in Pharmaceutical Markets. Abstract

  The extent of pharmaceutical advertising and promotion can be characterized by a balancing act between profitable demand expansions and potentially unfavorable subsequent regulatory actions. However, this balance also depends on the nature of competition (e.g. monopoly versus oligopoly). In this paper we model the firm’s behavior under different competitive scenarios and test the model’s predictions using a novel combination of sales, promotion, advertising, and adverse event reports data. We focus on the market for erectile dysfunction drugs as the basis for estimation. This market is ideal for analysis as it is characterized by an abrupt shift in structure, all drugs are branded, the drugs are associated with adverse health events, and have extensive advertising and promotion. We find that advertising and promotion expenditures increase own market share but also increase the share of adverse drug reactions. Competitors’ spending decreases market share, while also having an influence on adverse drug reactions.

We will make extensive use of outside speakers, many of whom are true industry leaders within different sectors of the health care services industry. Speakers will address the current management issues they face in running their businesses as well as discuss the career decisions and leadership styles that enables them to reach the top of their profession. Students will be asked to develop a plan to both buy out and manage a specific health care services business of their choosing and will present their final plans to a panel of leading Health Care Private Equity investors who will evaluate their analysis.
