This paper investigates the potential of maternal and infant health programs to improve the life expectancy of women and children. We study a program trialed 1931-33 in seven Swedish medical districts, assembling individual data from parish records and aggregate data from annual reports of...

Taking a firm's competitive position into account benefits investors who are better at evaluating this qualitative information. I find that fund managers who overweight companies with market power outperform their peers. Placebo exercises and an exogenous shock to product market competition...

Processing qualitative information about a firm's product market competition matters for fund performance. I find that fund managers with a better understanding of a firm's market power exhibit a superior risk-adjusted performance. Managers who overweight companies with the fewest competitors...

Processing qualitative information about a firm's product market competition matters for professional investors. Consistent with a superior understanding of a firm's market power, fund managers who overweight companies with the fewest competitors (monopolies) outperform their peers. An exogenous...

Many health care systems aim to enhance hospital quality by encouraging competition. However, evidence on the relationship between quality and competition is inconclusive. My contribution to this literature is two-fold. Analyzing the relationship between competition and quality for the German...

This paper examines the effects of hospital case volume on quality of care on the example of intact abdominal aortic aneurysm (AAA) and hip fracture (HIP). We conduct the analysis on patient level with multiple logistic regression analysis. Quality is measured with a binary variable which...

Competing hospitals may not only use quality of service to attract patients but also their specialization profile. Applying a Hotelling-duopoly and interpreting respectively quality and specialization as vertical and horizontal differentiation, we analyze the optimal allocation in both...

Medical technological progress has been shown to be the main driver of health care costs. A key policy question is whether new treatment options are worth the additional costs. In this paper we assess the causal effect of percutaneous transluminal coronary angioplasty (PTCA), a major new heart...

New empirical evidence shows substantial heterogeneity in the altruism of healthcare providers. Spurred by this evidence, we build a spatial quality competition model with altruism heterogeneity. We find that more altruistic healthcare providers supply relatively higher quality levels and...
