We identify the impact of local firm concentration on incumbent performance with a quasi natural experiment. When Germany was divided after World War II, many firms in the machine tool industry fled the Soviet occupied zone to prevent expropriation. We show that the regional location decisions...

An extensive literature has documented a robust correlation between socioeconomic status--measured in a variety of ways--and health outcomes; however, much uncertainty remains regarding what causal processes underlie this association. The present paper builds on a growing literature that seeks...

The fraction of GDP devoted to health care in the United States is the highest in the world and rising rapidly. Recent economic studies have highlighted the growing value of health improvements, but less attention has been paid to the efficiency costs of tax-financed spending to pay for such...

We analyze whether decreased emergency department access (measured by increased driving time to the nearest ED) results in adverse patient outcomes or changes in the patient health profile for patients suffering from acute myocardial infarction. Data sources include 100% Medicare Provider...

Using 2006 China Agricultural Census (CAC), we examine whether the introduction of the New Cooperative Medical System (NCMS) has affected child mortality, maternal mortality, and school enrollment of the 6-16 years olds. Our data cover 5.9 million people living in eight low-income rural...

In spite of the large expected costs of needing long-term care, only 10-12 percent of the elderly population has private insurance coverage. Medicaid, which provides means-tested public assistance and pays for almost half of long-term care costs, spends more than $100 billion annually on...

We use simple economic insights to develop a framework for distinguishing between prejudice and statistical discrimination using observational data. We focus our inquiry on the enormous literature in healthcare where treatment disparities by race and gender are not explained by access,...

In recent years, child care subsidies have become an integral part of federal and state efforts to move economically disadvantaged parents from welfare to work. Although previous empirical studies consistently show that these employment-related subsidies raise work levels among this group,...

The recent reform of the U.S. health care system has been described both as a boon and a death blow for the healthcare industry and for private insurers in particular. We exploit the surprise election of Republican Scott Brown to the U.S. Senate, which dealt a serious blow to the prospects for...

We investigate the effect of therapeutic procedure innovation in general on the longevity of all hospital patients, i.e. patients with a variety of medical conditions. The analysis is based on data on over one million discharges from public and private hospitals in Western Australia (WA) during...
