Book excerpt: Over the last decades, health economics has turned into one of the most active research fields within economics. The structure of health care markets varies enormously across countries, largely influenced by competition among suppliers, the regulation of markets and patient preferences. This dissertation presents an analysis of health care markets especially focusing on price competition and quality competition. Under price competition, a pair of asymmetric pure strategy price equilibria exists in a model with income constraints for the specific case that two physicians locate at the maximum distance from each other and patients pay the same marginal transportation cost. Under quality competition, I investigate the interplay of market transparency and semi-altruism - a specific and interesting aspect unique to markets for health care. Market transparency and semi-altruism show ambiguous effects on welfare. The more altruistic physicians provides weakly higher quality than the less altruistic one. Moreover, I explore individual and social incentives for hospital mergers and their interaction with transparency and find that higher transparency does not always lead to higher quality and higher social welfare. The results indicate that quality is lower after merger. A hospital merger leads to a higher social welfare if the efficiency gains from the merger are sufficiently large. ; eng

This book was released on 2022 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States spends a larger percentage of GDP on healthcare than any other OECD nation, and yet it performs poorly on measures of access, process quality and outcomes relative to other wealthy nations. One hypothesis that may explain the relatively poor performance of the United States' healthcare system per dollar spent is that markets for hospitals, physician services, and insurance are highly consolidated and lack competition. This dissertation contributes to the body of literature seeking to measure healthcare market structure and assess the relationship between this market structure and unit prices, overall spending, and healthcare quality. The first paper in this dissertation, "The Association between Hospital-Physician Vertical Integration and Outpatient Physician Prices Paid by Commercial Insurers: New Evidence," demonstrates market-level associations between vertical integration among hospitals and physicians and higher prices for outpatient care. The second essay, "How Hospital-Owned Physician Organizations are Associated with Healthcare Prices, Expenditures, and Quality," analyzes vertical integration and prices, quality, and total patient spending, building on the findings of the first essay using physician and hospital level claims data. This study finds that vertical integration is associated with higher levels of annual spending for patients attributed to vertically integrated providers, but interpretation of association between vertical integration and outpatient prices is confounded by pre-intervention trends. Analysis of CMS hospital outcome measures does not show associations between vertical integration at a hospital level and quality. Finally, the third essay, "Automated Delineation of Hospital Market Boundaries in California," explores geographic market definition in healthcare, an important topic in research and antitrust action, while assessing the application of community detection methods in this field. This study finds that community detection methods group hospitals with higher accuracy than other geographic markets as measured by patient flows and may offer promise for merger screening, research on market concentration, and research on geographic variation in healthcare. The final chapter reviews overarching limitations of the dissertation, outlines directions for future research, and comments on potential policy approaches to promote competition and address the symptoms that may result from highly consolidated healthcare markets

Available in PDF, EPUB and Kindle. Book excerpt: In these essays, I empirically estimate the impact of interactions between primary care physicians (PCPs) and specialists on physician behavior. In the first chapter, I examine the impact that the acquisition of PCPs by firms employing specialists has on patient referral patterns in markets where integration takes place. In the second chapter, I estimate a model of physician entry behavior to understand the extent to which PCPs and specialists consider the number of physicians of the other type in the market when selecting which markets to enter.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Health care systems are complex organizations. Multiple agents interact in different settings to provide health care, each one of them with different objectives and information. How markets are organized and which actions are allowed, has a direct impact on the incentives agents face when making health care choices. In this dissertation, I study the determinants and effects of these choices on market outcomes, focusing on private health insurance markets. The first chapter provides insights about health insurance markets in which workers, rather than firms, choose insurance plans in an imperfect competition setting. Using a unique dataset that includes every person enrolled in private plans in Chile in 2009, I estimate underlying preference parameters over health insurance features. I find large heterogeneity in the valuation of these features across age-sex-groups and individual types. Individual characteristics play an important role on health plan choices and therefore, can be used by insurers to design plans targeted to specific groups and for patient selection. The second chapter presents a theoretical model where private insurers compete with a free public alternative to attract clients. Using a two-type model I show that if private insurance companies offer a non-rationing alternative and the public system rationing is done through random selection, an efficiency trap may exist. A marginal increase in the budget allocated to the public system can potentially reduce the expected welfare for all types. This result extends to a model with multiple types, but the negative welfare impact is offset by a crowding-in effect among the rich. Finally, the third chapter provides a general analytical framework that can be used to evaluate risk selection under different health care models. The model is based on the interactions between the four key agents present in every health care system: sponsors, health plans, providers and customers. This framework is used to review risk selection in four countries in the Americas -Canada, Chile, Colombia, and the U.S.-, showing how regulatory policies both create and ameliorate it, and in some cases are as important as risk adjustment, risk sharing and risk selection strategies for reducing risk selection.

Available in PDF, EPUB and Kindle. Book excerpt: "The goal of this paper is to identify key issues concerning the nature of competition in health care markets and its impacts on quality and social welfare and to identify pertinent findings from the theoretical and empirical literature on this topic. The theoretical literature in economics on competition and quality, the theoretical literature in health economics on this topic, and the empirical findings on competition and quality in health care markets are surveyed and their findings assessed.Theory is clear that competition increases quality and improves consumer welfare when prices are regulated (for prices above marginal cost), although the impacts on social welfare are ambiguous. When firms set both price and quality, both the positive and normative impacts of competition are ambiguous. The body of empirical work in this area is growing rapidly. At present it consists entirely of work on hospital markets. The bulk of the empirical evidence for Medicare patients shows that quality is higher in more competitive markets. The empirical results for privately insured patients are mixed across studies"--National Bureau of Economic Research web site.

Available in PDF, EPUB and Kindle. Book excerpt: The health care industry is being transformed. Large firms are merging and acquiring other firms. Alliances and contractual relations between players in this market are shifting rapidly. Within the next few years, many markets are predicted to be dominated by a few large firms. Antitrust enforcement authorities like the Department of Justice and the Federal Trade Commission, as well as courts and legislators at both the federal and state levels, are struggling with the implications of these changes for the nature and consequences of competition in health care markets. In this paper, we summarize the nature of the changes in the structure of the health care industry. We will focus on the markets for health insurance, hospital services, and physician services. We will discuss the potential implications of the restructuring of the health care industry for competition, efficiency, and public policy. As will become apparent, this area offers a number of intriguing questions for inquisitive researchers.

Available in PDF, EPUB and Kindle. Book excerpt: "Competition. Deregulation. Free market forces. The debate over competition in health care that raged in the 1970s brought with it a new economic jargon, a vocabulary of concepts and issues unheard of in hospitals a decade earlier. "Competition in health care has developed to a greater degree than most economists predicted ten years ago. That is the conclusion of Warren Greenberg in his introduction to Competition in the Health Care Sector: Ten Years Later, a retrospective of a 1977 Federal Trade Commission conference, which produced the landmark treatise Competition in the Health Care Sector: Past, Present, and Future. Seven of the ten original papers are reexamined; a chapter on the nursing home industry has been added. "As with the original volume, Greenberg predicts that the retrospective will become a critical element in the health care economic literature."--Hospitals

Available in PDF, EPUB and Kindle. Book excerpt: This volume revisits the Nobel Prize-winning economist Kenneth Arrow’s classic 1963 essay “Uncertainty and the Welfare Economics of Medical Care” in light of the many changes in American health care since its publication. Arrow’s groundbreaking piece, reprinted in full here, argued that while medicine was subject to the same models of competition and profit maximization as other industries, concepts of trust and morals also played key roles in understanding medicine as an economic institution and in balancing the asymmetrical relationship between medical providers and their patients. His conclusions about the medical profession’s failures to “insure against uncertainties” helped initiate the reevaluation of insurance as a public and private good. Coming from diverse backgrounds—economics, law, political science, and the health care industry itself—the contributors use Arrow’s article to address a range of present-day health-policy questions. They examine everything from health insurance and technological innovation to the roles of charity, nonprofit institutions, and self-regulation in addressing medical needs. The collection concludes with a new essay by Arrow, in which he reflects on the health care markets of the new millennium. At a time when medical costs continue to rise, the ranks of the uninsured grow, and uncertainty reigns even among those with health insurance, this volume looks back at a seminal work of scholarship to provide critical guidance for the years ahead.

Book excerpt: This paper reviews the literature devoted to studying markets for health care services and health insurance. There has been tremendous growth and progress in this field. A tremendous amount of new research has been done in this area over the last 10 years. In addition, there has been increasing development and use of frontier industrial organization methods. We begin by examining research on the determinants of market structure, considering both static and dynamic models. We then model the strategic determination of prices between health insurers and providers where insurers market their products to consumers based, in part, on the quality and breadth of their provider network. We then review the large empirical literature on the strategic determination of hospital prices through the lens of this model. Variation in the quality of health care clearly can have large welfare consequences. We therefore also describe the theoretical and empirical literature on the impact of market structure on quality of health care. The paper then moves on to consider competition in health insurance markets and physician services markets. We conclude by considering vertical restraints and monopsony power.
