Diagnostic Uncertainty and Insurance Coverage in Credence Goods Markets


Book Description

Credence goods markets - like for health care or repair services - with their informational asymmetries between sellers and customers are prone to fraudulent behavior of sellers and resulting market inefficiencies. We present the first model that considers both diagnostic uncertainty of sellers and the effects of insurance coverage of consumers in a unified framework. We test the model's predictions in a laboratory experiment. Both in theory and in the experiment diagnostic uncertainty decreases the rate of efficient service provision and leads to less trade. In theory, insurance also decreases the rate of efficient service provision, but at the same time it also increases the volume of trade, leading to an ambiguous net effect on welfare. In the experiment, the net effect of insurance coverage on efficiency turns out to be positive. We also uncover an important interaction effect: if consumers are insured, experts invest less in diagnostic precision. We discuss policy implications of our results.




Diagnostic Uncertainty and Insurance in Credence Goods Markets


Book Description

Credence goods markets - like health care or repair services - with their informational asymmetries between expert sellers and uninformed customers are prone to fraudulent behavior of sellers and resulting market inefficiencies. Only little is known so far about how diagnostic uncertainty of sellers affects market outcomes, and how one widespread feature of such markets, insurance on the customer side, interacts with the degree of diagnostic uncertainty. We present a model that analyzes the effects of both diagnostic uncertainty and insurance in a unified framework and we test the model's predictions in lab experiments. Both in theory and in the experiment diagnostic uncertainty increases the rate of incorrect service provision and leads to less trade, thus reducing efficiency. In theory, insurance also increases the provision of incorrect services, but at the same time it also increases the volume of trade leading to an ambiguous net effect on welfare. In the experiments the net effect of insurance coverage on efficiency turns out to be negative. We also find an important interaction effect: if consumers are insured, experts invest less in diagnostic precision.




Serving Consumers in an Uncertain World


Book Description

Credence goods markets are prone to fraudulent behavior and market inefficiencies due to informational asymmetries between sellers and customers. We examine experimentally the effects of diagnostic uncertainty and insurance coverage on the information acquisition and provision decisions by sellers and the trading decisions by consumers. Our results reveal that diagnostic uncertainty is a major source of inefficiency by decreasing efficient service provision. Insurance coverage has a positive net effect on market efficiency, despite making information acquisition and efficient service provision less likely. We also examine the role of -s and of sellers' prosociality in shaping service provision and information acquisition.
















Handbook of Healthcare Analytics


Book Description

How can analytics scholars and healthcare professionals access the most exciting and important healthcare topics and tools for the 21st century? Editors Tinglong Dai and Sridhar Tayur, aided by a team of internationally acclaimed experts, have curated this timely volume to help newcomers and seasoned researchers alike to rapidly comprehend a diverse set of thrusts and tools in this rapidly growing cross-disciplinary field. The Handbook covers a wide range of macro-, meso- and micro-level thrusts—such as market design, competing interests, global health, personalized medicine, residential care and concierge medicine, among others—and structures what has been a highly fragmented research area into a coherent scientific discipline. The handbook also provides an easy-to-comprehend introduction to five essential research tools—Markov decision process, game theory and information economics, queueing games, econometric methods, and data science—by illustrating their uses and applicability on examples from diverse healthcare settings, thus connecting tools with thrusts. The primary audience of the Handbook includes analytics scholars interested in healthcare and healthcare practitioners interested in analytics. This Handbook: Instills analytics scholars with a way of thinking that incorporates behavioral, incentive, and policy considerations in various healthcare settings. This change in perspective—a shift in gaze away from narrow, local and one-off operational improvement efforts that do not replicate, scale or remain sustainable—can lead to new knowledge and innovative solutions that healthcare has been seeking so desperately. Facilitates collaboration between healthcare experts and analytics scholar to frame and tackle their pressing concerns through appropriate modern mathematical tools designed for this very purpose. The handbook is designed to be accessible to the independent reader, and it may be used in a variety of settings, from a short lecture series on specific topics to a semester-long course.

Dumbing Down


Book Description

This open access book examines the challenges and issues caused by a move to a marketized education system in Sweden. Observing the introduction of the school voucher system and a postmodern social constructivist view of knowledge, the move away from objective knowledge is identified as the core reason for Sweden’s current education crisis. The impact of declining education standards on the labor market is also discussed. This book highlights the issues seen in Sweden and suggests policies that can improve education in the rest of the Western world as well. It will be relevant to students and researchers interested in education and labor economics.
