Download or read book Evaluating Wireless Carrier Consolidation Using Semiparametric Demand Estimation written by Patrick L. Bajari and published by . This book was released on 2006 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The US mobile phone service industry has dramatically consolidated over the last two decades. One justification for consolidation is that merged firms can provide consumers with larger coverage areas at lower costs. We estimate the willingness to pay for national coverage to evaluate this motivation for past consolidation. As market level quantity data is not publicly available, we devise an econometric procedure that allows us to estimate the willingness to pay using market share ranks collected from a popular online retailer, Amazon. Our semiparametric maximum score estimator controls for consumers' heterogeneous preferences for carriers, handsets and minutes of calling time. We find that national coverage is strongly valued by consumers, providing an efficiency justification for across-market mergers. The methods we propose can estimate demand for other products using data from Amazon or other online retailers where quantities are not observed, but product ranks are observed. Since Amazon data can easily be gathered by researchers, these methods may be useful for the analysis of other product markets where high quality data are not publicly available.

Download or read book Seduction by Contract written by Oren Bar-Gill and published by OUP Oxford. This book was released on 2012-08-23 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consumers routinely enter into long-term contracts with providers of goods and services - from credit cards, mortgages, cell phones, insurance, TV, and internet services to household appliances, theatre and sports events, health clubs, magazine subscriptions, transportation, and more. Across these consumer markets certain design features of contracts are recurrent, and puzzling. Why do sellers design contracts to provide short-term benefits and impose long-term costs? Why are low introductory prices so common? Why are the contracts themselves so complex, with numerous fees and interest rates, tariffs and penalties? Seduction by Contract explains how consumer contracts emerge from the interaction between market forces and consumer psychology. Consumers are short-sighted and optimistic, so sellers compete to offer short-term benefits, while imposing long-term costs. Consumers are imperfectly rational, so sellers hide the true costs of products and services in complex contracts. Consumers are seduced by contracts that increase perceived benefits, without actually providing more benefits, and decrease perceived costs, without actually reducing the costs that consumers ultimately bear. Competition does not help this behavioural market failure. It may even exacerbate it. Sellers, operating in a competitive market, have no choice but to align contract design with the psychology of consumers. A high-road seller who offers what she knows to be the best contract will lose business to the low-road seller who offers what the consumer mistakenly believes to be the best contract. Put bluntly, competition forces sellers to exploit the biases and misperceptions of their customers. Seduction by Contract argues that better legal policy can help consumers and enhance market efficiency. Disclosure mandates provide a promising avenue for regulatory intervention. Simple, aggregate disclosures can help consumers make better choices. Comprehensive disclosures can facilitate the work of intermediaries, enabling them to better advise consumers. Effective disclosure would expose the seductive nature of consumer contracts and, as a result, reduce sellers' incentives to write inefficient contracts. Developing its explanation through a general framework and detailed case studies of three major consumer markets (credit cards, mortgages, and cell phones), Seduction by Contract is an accessible introduction to the law and economics of consumer contracts, and a powerful critique of current regulatory policy.

Download or read book Employer Matching and 401 k Saving written by Gary V. Engelhardt and published by . This book was released on 2006 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Employer matching of employee 401(k) contributions can provide a powerful incentive to save for retirement and is a key component in pension-plan design in the United States. Using detailed administrative contribution, earnings, and pension-plan data from the Health and Retirement Study, this analysis formulates a life-cycle-consistent econometric specification of 401(k) saving and estimates the determinants of saving accounting for non-linearities in the household budget set induced by matching. The participation estimates indicate that an increase in the match rate by 25 cents per dollar of employee contribution raises 401(k) participation by 3.75 to 6 percentage points, and the estimated elasticity of participation with respect to matching ranges from 0.02-0.07. The parametric and semi-parametric estimates for saving indicate that an increase in the match rate by 25 cents per dollar of employee contribution raises 401(k) saving by $400-$700 (in 1991 dollars). The estimated elasticity of 401(k) saving to matching is also small and ranges from 0.09-0.12 overall, with just under half of this effect on the intensive margin. Overall, the analysis reveals that matching is a rather poor policy instrument with which to raise retirement saving.
Download or read book Corruption Perceptions Vs Corruption Reality written by Benjamin A. Olken and published by . This book was released on 2006 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This paper examines the accuracy of beliefs about corruption, using data from Indonesian villages. Specifically, I compare villagers' stated beliefs about the likelihood of corruption in a road building project in their village with a more objective measure of missing expenditures' in the project, which I construct by comparing the projects official expenditure reports with an independent estimate of the prices and quantities of inputs used in construction. I find that villagers' beliefs do contain information about corruption in the road project, and that villagers are sophisticated enough to distinguish between corruption in the road project and other types of corruption in the village. The magnitude of their information, however, is small, in part because officials hide corruption where it is hardest for villagers to detect. This may limit the effectiveness of grass-roots monitoring of local officials. I also find evidence of systematic biases in corruption beliefs, particularly when examining the relationship between corruption and variables correlated with trust. For example, ethnically heterogeneous villages have higher perceived corruption levels but lower actual levels of missing expenditures. The findings illustrate the limitations of relying solely on corruption perceptions, whether in designing anti-corruption policies or in conducting empirical research on corruption"--National Bureau of Economic Research web site.
Download or read book Swing Pricing and Fragility in Open end Mutual Funds written by Dunhong Jin and published by International Monetary Fund. This book was released on 2019-11-01 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to prevent runs on open-end mutual funds? In recent years, markets have observed an innovation that changed the way open-end funds are priced. Alternative pricing rules (known as swing pricing) adjust funds’ net asset values to pass on funds’ trading costs to transacting shareholders. Using unique data on investor transactions in U.K. corporate bond funds, we show that swing pricing eliminates the first-mover advantage arising from the traditional pricing rule and significantly reduces redemptions during stress periods. The positive impact of alternative pricing rules on fund flows reverses in calm periods when costs associated with higher tracking error dominate the pricing effect.
Download or read book Moral Hazard in Health Insurance written by Amy Finkelstein and published by Columbia University Press. This book was released on 2014-12-02 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the challenge of covering heath care expenses—while minimizing economic risks. Moral hazard—the tendency to change behavior when the cost of that behavior will be borne by others—is a particularly tricky question when considering health care. Kenneth J. Arrow’s seminal 1963 paper on this topic (included in this volume) was one of the first to explore the implication of moral hazard for health care, and Amy Finkelstein—recognized as one of the world’s foremost experts on the topic—here examines this issue in the context of contemporary American health care policy. Drawing on research from both the original RAND Health Insurance Experiment and her own research, including a 2008 Health Insurance Experiment in Oregon, Finkelstein presents compelling evidence that health insurance does indeed affect medical spending and encourages policy solutions that acknowledge and account for this. The volume also features commentaries and insights from other renowned economists, including an introduction by Joseph P. Newhouse that provides context for the discussion, a commentary from Jonathan Gruber that considers provider-side moral hazard, and reflections from Joseph E. Stiglitz and Kenneth J. Arrow. “Reads like a fireside chat among a group of distinguished, articulate health economists.” —Choice
Download or read book Nonparametric Econometrics written by Qi Li and published by Princeton University Press. This book was released on 2023-07-18 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive, up-to-date textbook on nonparametric methods for students and researchers Until now, students and researchers in nonparametric and semiparametric statistics and econometrics have had to turn to the latest journal articles to keep pace with these emerging methods of economic analysis. Nonparametric Econometrics fills a major gap by gathering together the most up-to-date theory and techniques and presenting them in a remarkably straightforward and accessible format. The empirical tests, data, and exercises included in this textbook help make it the ideal introduction for graduate students and an indispensable resource for researchers. Nonparametric and semiparametric methods have attracted a great deal of attention from statisticians in recent decades. While the majority of existing books on the subject operate from the presumption that the underlying data is strictly continuous in nature, more often than not social scientists deal with categorical data—nominal and ordinal—in applied settings. The conventional nonparametric approach to dealing with the presence of discrete variables is acknowledged to be unsatisfactory. This book is tailored to the needs of applied econometricians and social scientists. Qi Li and Jeffrey Racine emphasize nonparametric techniques suited to the rich array of data types—continuous, nominal, and ordinal—within one coherent framework. They also emphasize the properties of nonparametric estimators in the presence of potentially irrelevant variables. Nonparametric Econometrics covers all the material necessary to understand and apply nonparametric methods for real-world problems.

Download or read book Platforms Markets and Innovation written by Annabelle Gawer and published by Edward Elgar Publishing. This book was released on 2011-01-01 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: In her pioneering book Platform Leadership (with Michael Cusumano), Gawer gave us the strategy of building coalitions of customers, suppliers, and complementors. Now, she brings together a number of the leading researchers in the area of platform strategy to give us a book that will be a key reference for both practitioners and academics. Adam Brandenburger, New York University, US Annabelle Gawer s collected volume of research shows that a vibrant community of scholars has arisen around platforms and innovation. Each of the chapters is first rate, with top researchers offering some of their latest work. This will be an indispensable book for students of innovation and technology management everywhere. Henry Chesbrough, University of California, Berkeley, US Annabelle Gawer s Platforms, Markets and Innovation is the first serious exploration of the critical but subtle role that platforms play in business, society and our personal lives. As digital technologies penetrate every nook and cranny of the world around us, we rely on platforms to both help us use the new technologies, as well as to organize new markets of innovation that add applications on top of the platforms and make them far more valuable. Dr Gawer s excellent book is designed to help us understand the mysterious nature of platforms. It brings together the insights of twenty-four experts around the world who contributed to the fourteen chapters of the book. Dr Gawer s book is invaluable to anyone trying to understand the nuanced nature of platforms, and their implications for the evolution of innovation in the 21st century. Irving Wladawsky-Berger, IBM Academy of Technology, US The emergence of platforms is a novel phenomenon impacting most industries, from products to services. Industry platforms such as Microsoft Windows or Google, embedded within industrial ecosystems, have redesigned our industrial landscapes, upset the balance of power between firms, fostered innovation and raised new questions on competition and innovation. Annabelle Gawer presents cutting-edge contributions from 24 top international scholars from 19 universities across Europe, the USA and Asia, from the disciplines of strategy, economics, innovation, organization studies and knowledge management. The novel insights assembled in this volume constitute a fundamental step towards an empirically based, nuanced understanding of the nature of platforms and the implications they hold for the evolution of industrial innovation. The book provides an overview of platforms and discusses governance, management, design and knowledge issues. With a multidisciplinary approach, this book will strongly appeal to academics and advanced students in management, innovation, strategy, economics and design. It will also prove an enlightening read for business managers in IT industries.

Download or read book Decision Making under Deep Uncertainty written by Vincent A. W. J. Marchau and published by Springer. This book was released on 2019-04-04 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book focuses on both the theory and practice associated with the tools and approaches for decisionmaking in the face of deep uncertainty. It explores approaches and tools supporting the design of strategic plans under deep uncertainty, and their testing in the real world, including barriers and enablers for their use in practice. The book broadens traditional approaches and tools to include the analysis of actors and networks related to the problem at hand. It also shows how lessons learned in the application process can be used to improve the approaches and tools used in the design process. The book offers guidance in identifying and applying appropriate approaches and tools to design plans, as well as advice on implementing these plans in the real world. For decisionmakers and practitioners, the book includes realistic examples and practical guidelines that should help them understand what decisionmaking under deep uncertainty is and how it may be of assistance to them. Decision Making under Deep Uncertainty: From Theory to Practice is divided into four parts. Part I presents five approaches for designing strategic plans under deep uncertainty: Robust Decision Making, Dynamic Adaptive Planning, Dynamic Adaptive Policy Pathways, Info-Gap Decision Theory, and Engineering Options Analysis. Each approach is worked out in terms of its theoretical foundations, methodological steps to follow when using the approach, latest methodological insights, and challenges for improvement. In Part II, applications of each of these approaches are presented. Based on recent case studies, the practical implications of applying each approach are discussed in depth. Part III focuses on using the approaches and tools in real-world contexts, based on insights from real-world cases. Part IV contains conclusions and a synthesis of the lessons that can be drawn for designing, applying, and implementing strategic plans under deep uncertainty, as well as recommendations for future work. The publication of this book has been funded by the Radboud University, the RAND Corporation, Delft University of Technology, and Deltares.
Download or read book Quantifying Systemic Risk written by Joseph G. Haubrich and published by University of Chicago Press. This book was released on 2013-01-24 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the aftermath of the recent financial crisis, the federal government has pursued significant regulatory reforms, including proposals to measure and monitor systemic risk. However, there is much debate about how this might be accomplished quantitatively and objectively—or whether this is even possible. A key issue is determining the appropriate trade-offs between risk and reward from a policy and social welfare perspective given the potential negative impact of crises. One of the first books to address the challenges of measuring statistical risk from a system-wide persepective, Quantifying Systemic Risk looks at the means of measuring systemic risk and explores alternative approaches. Among the topics discussed are the challenges of tying regulations to specific quantitative measures, the effects of learning and adaptation on the evolution of the market, and the distinction between the shocks that start a crisis and the mechanisms that enable it to grow.
Download or read book Good Economics for Hard Times written by Abhijit V. Banerjee and published by PublicAffairs. This book was released on 2019-11-12 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The winners of the Nobel Prize show how economics, when done right, can help us solve the thorniest social and political problems of our day. Figuring out how to deal with today's critical economic problems is perhaps the great challenge of our time. Much greater than space travel or perhaps even the next revolutionary medical breakthrough, what is at stake is the whole idea of the good life as we have known it. Immigration and inequality, globalization and technological disruption, slowing growth and accelerating climate change--these are sources of great anxiety across the world, from New Delhi and Dakar to Paris and Washington, DC. The resources to address these challenges are there--what we lack are ideas that will help us jump the wall of disagreement and distrust that divides us. If we succeed, history will remember our era with gratitude; if we fail, the potential losses are incalculable. In this revolutionary book, renowned MIT economists Abhijit V. Banerjee and Esther Duflo take on this challenge, building on cutting-edge research in economics explained with lucidity and grace. Original, provocative, and urgent, Good Economics for Hard Times makes a persuasive case for an intelligent interventionism and a society built on compassion and respect. It is an extraordinary achievement, one that shines a light to help us appreciate and understand our precariously balanced world.
