The landscape of the U.S. healthcare industry is changing dramatically as healthcare providers expand both within and across markets. While federal antitrust agencies have mounted several challenges to same-market combinations, they have not challenged any non-horizontal affiliations - including...

A substantial literature has studied the influence of malpractice pressure on physician behavior. However, these studies generally focus on malpractice pressure stemming from state laws that govern liability exposure, which may be unknown or not salient to physicians. We test how physicians...

This paper reviews the evidence on the well-known positive association between socioeconomic status and health. We focus on four dimensions of socioeconomic status -- education, financial resources, rank, and race and ethnicity -- paying particular attention to how the mechanisms linking health...

Standard theories of insurance, dating from Rothschild and Stiglitz (1976), stress the role of adverse selection in explaining the decision to purchase insurance. In these models, higher risk people buy full or near-full insurance, while lower risk people buy less complete coverage, if they buy...
