Pricing and welfare in health plan choice by M. Kate Bundorf( Book )
6 editions published in 2008 in English and held by 18 libraries worldwide
Prices in government and employer-sponsored health insurance markets only partially reflect insurers' expected costs of coverage for different enrollees. This can create inefficient distortions when consumers self-select into plans. We develop a simple model to study this problem and estimate it using new data on small employers. In the markets we observe, the welfare loss compared to the feasible efficient benchmark is around 2-11% of coverage costs. Three-quarters of this is due to restrictions on risk-rating employee contributions; the rest is due to inefficient contribution choices. Despite the inefficiency, we find substantial benefits from plan choice relative to single-insurer options
Empirical industrial organization : a progress report by Liran Einav( Book )
7 editions published between 2010 and 2011 in English and held by 13 libraries worldwide
The field of Industrial Organization has made dramatic advances over the last few decades in developing empirical methods for analyzing imperfect competition and the organization of markets. We describe the motivation for these developments and some of the successes. We also discuss the relative emphasis that applied work in the field has placed on economic theory relative to statistical research design, and the possibility that a focus on methodological innovation has crowded out applications. We offer some suggestions about how the field may progress in coming years
Reinventing the Way we do Business by Jon Levin by Edward E Whitacre( visu )
1 edition published in 2013 in English and held by 12 libraries worldwide
After a long and distinguished career leading what has been called by Fortune magazine "the most admired telecommunications company in America," Ed Whitacre was called out of retirement to save GM and the potentially millions of jobs dependent on its survival. In this session, Jon Levin, Stanford University Professor and Economics Department Chair, leads an insightful interview in which Ed Whitacre shares, vividly, leadership lessons learned and the core management principles that catapulted him to 17 years as chairman and CEO of AT&T and, temporarily lured out of retirement, as chairman and CEO of General Motors Co
Beyond testing : empirical models of insurance markets by Liran Einav( Book )
2 editions published in 2009 in English and held by 8 libraries worldwide
We describe recent advances in the empirical analysis of insurance markets. This new research proposes ways to estimate individual demand for insurance and the relationship between prices and insurer costs in the presence of adverse and advantageous selection. We discuss how these models permit the measurement of welfare distortions arising from asymmetric information and the welfare consequences of potential government policy responses. We also discuss some challenges in modeling imperfect competition between insurers, and outline a series of open research questions
Early admissions at selective colleges by Christopher Avery( Book )
6 editions published in 2009 in English and held by 8 libraries worldwide
Early admissions is widely used by selective colleges and universities. We identify some basic facts about early admissions policies, including the admissions advantage enjoyed by early applicants and patterns in application behavior, and propose a game-theoretic model that matches these facts. The key feature of the model is that colleges want to admit students who are enthusiastic about attending, and early admissions programs give students an opportunity to signal this enthusiasm
Winning play in spectrum auctions by Jeremy Bulow( Book )
2 editions published in 2009 in English and held by 7 libraries worldwide
We describe factors that make bidding in large spectrum auctions complex -- including exposure and budget problems, the role of timing within an ascending auction, and the possibilities for price forecasting -- and how economic and game-theoretic analysis can assist bidders in overcoming these problems. We illustrate with the case of the FCC's Advanced Wireless Service auction, in which a new entrant, SpectrumCo, faced all these problems yet managed to purchase nationwide coverage at a discount of roughly a third relative to the prices paid by its incumbent competitors in the same auction, saving more than a billion dollars

Vertical integration and market structure by Timothy F Bresnahan( Book )
4 editions published in 2012 in English and held by 4 libraries worldwide
Contractual theories of vertical integration derive firm boundaries as an efficient response to market transaction costs. These theories predict a relationship between underlying features of transactions and observed integration decisions. There has been some progress in testing these predictions, but less progress in quantifying their importance. One difficulty is that empirical applications often must consider firm structure together with industry structure. Research in industrial organization frequently has adopted this perspective, emphasizing how scale and scope economies, and strategic considerations, influence patterns of industry integration. But this research has paid less attention to contractual or organizational details, so that these two major lines of research on vertical integration have proceeded in parallel with only rare intersection. We discuss the value of combining different viewpoints from organizational economics and industrial organization
The data revolution and economic analysis by Liran Einav( Book )
3 editions published in 2013 in English and held by 4 libraries worldwide
Many believe that "big data" will transform business, government and other aspects of the economy. In this article we discuss how new data may impact economic policy and economic research. Large-scale administrative datasets and proprietary private sector data can greatly improve the way we measure, track and describe economic activity. They also can enable novel research designs that allow researchers to trace the consequences of different events or policies. We outline some of the challenges in accessing and making use of these data. We also consider whether the big data predictive modeling tools that have emerged in statistics and computer science may prove useful in economics
Relational contracts, incentives and information by Jonathan D Levin( Archival Material )

The economics of internet markets by Jonathan D Levin( Book )
7 editions published in 2011 in English and held by 3 libraries worldwide
The internet has facilitated the creation of new markets characterized by large scale, increased customization, rapid innovation and the collection and use of detailed consumer and market data. I describe these changes and some of the economic theory that has been useful for thinking about online advertising markets, retail and business-to-business e-commerce, internet job matching and financial exchanges, and other internet platforms. I also discuss the empirical evidence on competition and consumer behavior in internet markets and some directions for future research
Essays in applied microeconometrics by Dominic Coey( file )
1 edition published in 2013 in English and held by 2 libraries worldwide
This subject of this dissertation is applied microeconometrics. Chapter 1 estimates the effect of physician incentives on treatment choices in heart attack management. Our results suggest that if physicians received bundled payments instead of fee-for-service incentives, heart attack management would become considerably more conservative, and about 20 percent of patients would receive different treatments. Chapter 2 studies the effect of Medicaid on health expenditures. At age 19, some enrollees lose Medicaid eligibility. We find that this quasi-experimental loss of coverage causes substantial changes to the level and composition of health care use. Average health expenditure falls by around 60 percent. Chapter 3 compares set-asides and subsidies in government procurement auctions. Restricting entry appears to substantially reduces efficiency and revenue, although it increases participation of favored bidders
Can health insurance competition work? : evidence from Medicare Advantage by Vilsa E Curto( Book )
2 editions published in 2014 in English and held by 2 libraries worldwide
We estimate the economic surplus created by Medicare Advantage under its reformed competitive bidding rules. We use data on the universe of Medicare beneficiaries, and develop a model of plan bidding that accounts for both market power and risk selection. We find that private plans have costs around 12% below fee-for-service costs, and generate around $50 dollars in surplus on average per enrollee-month, after accounting for the disutility due to enrollees having more limited choice of providers. Taxpayers provide a large additional subsidy, and insurers capture most of the private gains. We use the model to evaluate possible program changes
Sales taxes and Internet commerce by Liran Einav( Book )
2 editions published in 2012 in English and held by 1 library worldwide
We estimate the sensitivity of Internet retail purchasing to sales taxes using data from the eBay marketplace. Our first approach exploits the fact that seller locations are revealed only after buyers have expressed interest in an item by clicking on its listing. We use millions of location "surprises" to estimate price elasticities with respect to the effective sales tax. We then use aggregated data to estimate cross-state substitution parameters, and substitution between offline and online purchases, relying on the variation in state and local sales taxes, and on changes in these rates over time. We find substantial sensitivity to sales taxes. Using our item-level approach, we find a price elasticity of around -2 for interested buyers. Using our aggregate approach, we find that a one percentage point increase in a state's sales tax increases online purchases by state residents by just under two percent, but decreases their online purchases from home-state retailers by 3-4 percent
Essays on the determinants of student choices and educational outcomes by Justin A Wong( Computer File )
1 edition published in 2011 in English and held by 1 library worldwide
This dissertation is composed of three essays. Essay 1, "Does School Start Too Early For Student Learning?", considers the connection between school start time and student performance. Biological evidence indicates that adolescents' internal clocks are designed to make them fall asleep and wake up at later times than adults. This science has prompted widespread debate about delaying school start times in the U.S., a country which has some of the earliest start times worldwide. The debate suffers, however, from a glaring absence of evidence: the small number of prior studies has been too low powered statistically to test whether later start times improve achievement. I fill the gap by studying achievement across a large, nationally representative set of high schools that have varying start times. I identify the positive effect of later clock start times, as well as the independent effect of greater daylight at school start time. My primary empirical method is cross-sectional regression with rich controls for potentially confounding variables. The findings are confirmed by regression discontinuity analysis focused on schools close to time zone boundaries. I quantify the net gain in welfare from having an additional hour of sunlight before school starts by comparing the substantial lifetime earnings benefits for students against the likely the societal costs. Essay 2, "Student Success and Teaching Assistant Effectiveness In Large Classes", considers the impact teaching assistants (TAs) have on student performance. In universities, TAs play a crucial role by providing small group instruction in lecture courses with large enrollment. The multiplicity of TAs creates both positive opportunities and negative incentives. On the one hand, some TAs may excel at tasks--such as helping struggling students--at which other TAs fail. If so, all students may be able to learn better if they can match themselves to the TA that best suits their needs. On the other hand, the multiplicity of TAs means that students in the same class often receive instruction that varies in quality even though they are ultimately graded on the same standard. In this paper, we use data from a large lecture course in which students are conditionally randomly assigned to TAs. In addition to administrative data on scores and grades, we use survey data (which we generated) on students' initial preparation, their study habits, and their interactions with TAs. We identify the existence of variation among TAs in teaching effectiveness. We also identify how TAs vary in their effectiveness with certain subpopulations of students: the least and best prepared, students with different backgrounds, and so on. Using our parameter estimates, we simulate student achievement under scenarios such as random assignment to TAs, elimination/retraining of the least effective TAs, and matching of TAs to students based on initial information to show the potential gains in student welfare from more efficient matching. Essay 3, "A Study of Student Majors: A Historical Perspective", considers whether differing financial returns across degrees are a significant factor in a student's choice of a major. During the late 1990s, the U.S. experienced a technology boom that significantly increased the initial salary offers to engineering students, and computer science students in particular. These dramatic increases in returns provide an excellent opportunity to examine not only how students respond to salary levels, but also to salary trends. The existing literature has focused on the extent to which differing financial returns can affect a student's choice of undergraduate major. This paper extends the analysis to test if trends in salary levels also affect the share of students selecting into various majors using a comprehensive dataset of all post-secondary institutions. I find that students select into majors that offer higher salaries and have greater wage growth. Using a flexible empirical model that allows students to respond to both changes in salary levels and growth, I find that the results hold across majors and within engineering disciplines. These results help to explain why, for instance, the percentage of students choosing to major in computer science grew more rapidly than could be explained by salary level alone
Peer-to-peer markets by Liran Einav( Book )
2 editions published in 2015 in English and held by 1 library worldwide
Peer-to-peer markets such as eBay, Uber, and Airbnb allow small suppliers to compete with traditional providers of goods or services. We view the primary function of these markets as making it easy for buyers to find sellers and engage in convenient, trustworthy transactions. We discuss elements of market design that make this possible, including search and matching algorithms, pricing, and reputation systems. We then develop a simple model of how these markets enable entry by small or flexible suppliers, and the resulting impact on existing firms. Finally, we consider the regulation of peer-to-peer markets, and the economic arguments for different approaches to licensing and certification, data, and employment regulation
Learning from Seller Experiments in Online Markets by Liran Einav( Book )
3 editions published in 2011 in English and held by 1 library worldwide
The internet has dramatically reduced the cost of varying prices, displays and information provided to consumers, facilitating both active and passive experimentation. We document the prevalence of targeted pricing and auction design variation on eBay, and identify hundreds of thousands of experiments conducted by sellers across a wide array of retail products. We show how this type of data can be used to address questions about consumer behavior and market outcomes, and provide illustrative results on price dispersion, the frequency of over-bidding, the choice of reserve prices, "buy now" options and other auction design parameters, and on consumer sensitivity to shipping fees. We argue that leveraging the experiments of market participants takes advantage of the scale and heterogeneity of online markets and can be a powerful approach for testing and measurement
Trading mechanisms for financial exchanges by Patricia Macri-Lassus( Computer File )
1 edition published in 2010 in English and held by 1 library worldwide
The first part of this thesis discusses the structure of the US equities market and the regulatory challenges involved, with respect both to particular venues and order types, and to the market as a whole. This part addresses the role of public equities markets, their objectives, and the market-design concepts relevant to evaluating them, it describes the market structure before and after the significant regulatory reforms of 2005, goes on to detail some specific market-design challenges and current proposals from the SEC, and concludes with an analysis and evaluation of several trading mechanisms and three order types, from a mechanism-design perspective. The second part of the thesis presents a theoretical model of an exchange and analyzes optimal order submission in a one-shot game in which a buyer and seller, each of whom can have two (privately known) types, can trade up to two units of an asset through an order book, which is empty at the beginning of the game. In both a setting with private values and interdependent values, equilibria in four games are characterized: a basic game with limit and market orders, and games involving one of the three order types from the first part of the thesis- iceberg, discretionary, and volume orders. The effect of the introduction of the different order types is analyzed with respect to volume and transparency. Each setting also includes an analysis of the buyer-optimal mechanism and its relation to equilibria of the games involving orders
Are dynamic Vickrey auctions practical?: properties of the combinatorial clock auction by Jonathan D Levin( Book )
2 editions published in 2014 in English and held by 1 library worldwide
The combinatorial clock auction is becoming increasingly popular for large-scale spectrum awards and other uses, replacing more traditional ascending or clock auctions. We describe some surprising properties of the auction, including a wide range of ex post equilibria with demand expansion, demand reduction and predation. These outcomes arise because of the way the auction separates allocation and pricing, so that bidders are asked to make decisions that cannot possibly affect their own auction outcome. Our results obtain in a standard homogenous good setting where bidders have well-behaved linear demand curves, and suggest some practical difficulties with dynamic implementations of the Vickrey auction
Consumer price search and platform design in internet commerce by Michael Dinerstein( file )
1 edition published in 2014 in English and held by 0 libraries worldwide
Search frictions can explain why the "law of one price" fails in retail markets and why even firms selling commodity products have pricing power. In online commerce, physical search costs are low, yet price dispersion is common. We use browsing data from eBay to estimate a model of consumer search and price competition when retailers offer homogeneous goods. We find that retail margins are on the order of 10%, and use the model to analyze the design of search rankings. Our model explains most of the effects of a major re-design of eBay's product search, and allows us to identify conditions where narrowing consumer choice sets can be pro-competitive. Finally, we examine a subsequent A/B experiment run by eBay that illustrates the greater difficulties in designing search algorithms for differentiated products, where price is only one of the relevant product attributes
