Book excerpt: This dissertation considers inference in conditional moment inequality models. Chapter 1 derives the rate of convergence and asymptotic distribution for a class of Kolmogorov-Smirnov style test statistics for conditional moment inequality models for parameters on the boundary of the identified set under general conditions. In contrast to other moment inequality settings, the rate of convergence is faster than root-n, and the asymptotic distribution depends entirely on nonbinding moments. The results require the development of new techniques that draw a connection between moment selection, irregular identification, bandwidth selection and nonstandard M-estimation. Using these results, I propose tests that are more powerful than existing approaches for choosing critical values for this test statistic. I quantify the power improvement by showing that the new tests can detect alternatives that converge to points on the identified set at a faster rate than those detected by existing approaches. A monte carlo study confirms that the tests and the asymptotic approximations they use perform well in finite samples. In an application to a regression of prescription drug expenditures on income with interval data from the Health and Retirement Study, confidence regions based on the new tests are substantially tighter than those based on existing methods. Chapter 2 proposes confidence regions for the identified set in conditional moment inequality models using Kolmogorov-Smirnov statistics with a truncated inverse variance weighting with increasing truncation points. The new weighting differs from those proposed in the literature in two important ways. First, confidence regions based on KS tests with the weighting function I propose converge to the identified set at a faster rate than existing procedures based on bounded weight functions in a broad class of models. This provides a theoretical justification for inverse variance weighting in this context, and contrasts with analogous results for conditional moment equalities in which optimal weighting only affects the asymptotic variance. Second, the new weighting changes the asymptotic behavior, including the rate of convergence, of the KS statistic itself, requiring a new asymptotic theory in choosing the critical value, which I provide. To make these comparisons, I derive rates of convergence for the confidence regions I propose along with new results for rates of convergence of existing estimators under a general set of conditions. A series of examples illustrates the broad applicability of the conditions. A monte carlo study examines the finite sample behavior of the confidence regions. Chapter 3 derives bounds in empirical models of first price auctions with unobserved heterogeneity. Many empirical studies of auctions rely on the assumption that the researcher observes all variables that make auctions differ ex ante. When there is unobserved heterogeneity, the direction of the bias this causes is known only in a few restrictive examples. In this chapter, I show that ignoring unobserved heterogeneity in a first price sealed bid auction with symmetric independent private values gives bounds on several quantities of economic interest under surprisingly general conditions. These include bidder profits (which can be used to recover bid preparation costs in entry models) and the efficiency loss of assigning the object randomly. I then turn to estimation of these bounds, and show that, when only the winning bid is available, the rate of convergence can be slower than the square root of the number of auctions observed and depends on the number of bidders. These results apply more generally to estimation of functionals of a distribution from repeated observations of an order statistic and may be of independent interest. I apply these methods to bound the efficiency loss from replacing a set of procurement auctions for highway construction in Michigan with random assignment.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines methods for evaluating the causal effect of a treatment on a binary outcome using observational data, in which the treatment has not been assigned randomly. For example, consider estimating the average effect of attending a private high school on the probability of graduation. Although private schools may have higher graduation rates than public schools, perhaps the students who choose to attend private schools are better students initially and would perform well at public schools too. In such a case, the treatment exhibits selection bias, making it more difficult to estimate the causal treatment effect.

Available in PDF, EPUB and Kindle. Book excerpt: The National Book Critics Circle Award–winning author delivers a collection of essays that serve as the perfect “antidote to mansplaining” (The Stranger). In her comic, scathing essay “Men Explain Things to Me,” Rebecca Solnit took on what often goes wrong in conversations between men and women. She wrote about men who wrongly assume they know things and wrongly assume women don’t, about why this arises, and how this aspect of the gender wars works, airing some of her own hilariously awful encounters. She ends on a serious note— because the ultimate problem is the silencing of women who have something to say, including those saying things like, “He’s trying to kill me!” This book features that now-classic essay with six perfect complements, including an examination of the great feminist writer Virginia Woolf’s embrace of mystery, of not knowing, of doubt and ambiguity, a highly original inquiry into marriage equality, and a terrifying survey of the scope of contemporary violence against women. “In this series of personal but unsentimental essays, Solnit gives succinct shorthand to a familiar female experience that before had gone unarticulated, perhaps even unrecognized.” —The New York Times “Essential feminist reading.” —The New Republic “This slim book hums with power and wit.” —Boston Globe “Solnit tackles big themes of gender and power in these accessible essays. Honest and full of wit, this is an integral read that furthers the conversation on feminism and contemporary society.” —San Francisco Chronicle “Essential.” —Marketplace “Feminist, frequently funny, unflinchingly honest and often scathing in its conclusions.” —Salon

Book excerpt: From a leading authority on race and public policy, a deeply researched account of how families rise and fall today Since the Great Recession, most Americans' standard of living has stagnated or declined. Economic inequality is at historic highs. But inequality's impact differs by race; African Americans' net wealth is just a tenth that of white Americans, and over recent decades, white families have accumulated wealth at three times the rate of black families. In our increasingly diverse nation, sociologist Thomas M. Shapiro argues, wealth disparities must be understood in tandem with racial inequities -- a dangerous combination he terms "toxic inequality." In Toxic Inequality, Shapiro reveals how these forces combine to trap families in place. Following nearly two hundred families of different races and income levels over a period of twelve years, Shapiro's research vividly documents the recession's toll on parents and children, the ways families use assets to manage crises and create opportunities, and the real reasons some families build wealth while others struggle in poverty. The structure of our neighborhoods, workplaces, and tax code-much more than individual choices-push some forward and hold others back. A lack of assets, far more common in families of color, can often ruin parents' careful plans for themselves and their children. Toxic inequality may seem inexorable, but it is not inevitable. America's growing wealth gap and its yawning racial divide have been forged by history and preserved by policy, and only bold, race-conscious reforms can move us toward a more just society. "Everyone concerned about the toxic effects of inequality must read this book." -- Robert B. Reich "This is one of the most thought-provoking books I have read on economic inequality in the US." -- William Julius Wilson

Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) Finally, the third chapter, which is co-authored with Victor Chernozhukov and Emre Kocatulum, presents various set inference problems as they appear in finance and proposes practical and powerful inferential tools. Our tools will be applicable to any problem where the set of interest solves a system of smooth estimable inequalities, though we particularly focus on the following two problems: the admissible mean-variance sets of stochastic discount factors and the admissible mean-variance sets of asset portfolios. We propose to make inference on such sets using weighted likelihood-ratio and Wald type statistics, building upon and substantially enriching the available methods for inference on sets.

This book was released on 2012-08-01 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of articles that present the most recent cutting edge results on specification and estimation of economic models written by a number of the world’s foremost leaders in the fields of theoretical and methodological econometrics. Recent advances in asymptotic approximation theory, including the use of higher order asymptotics for things like estimator bias correction, and the use of various expansion and other theoretical tools for the development of bootstrap techniques designed for implementation when carrying out inference are at the forefront of theoretical development in the field of econometrics. One important feature of these advances in the theory of econometrics is that they are being seamlessly and almost immediately incorporated into the “empirical toolbox” that applied practitioners use when actually constructing models using data, for the purposes of both prediction and policy analysis and the more theoretically targeted chapters in the book will discuss these developments. Turning now to empirical methodology, chapters on prediction methodology will focus on macroeconomic and financial applications, such as the construction of diffusion index models for forecasting with very large numbers of variables, and the construction of data samples that result in optimal predictive accuracy tests when comparing alternative prediction models. Chapters carefully outline how applied practitioners can correctly implement the latest theoretical refinements in model specification in order to “build” the best models using large-scale and traditional datasets, making the book of interest to a broad readership of economists from theoretical econometricians to applied economic practitioners.
Download or read book Essays on Consumer Credit Markets written by Mark William Jenkins and published by Stanford University. This book was released on 2009 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies the organization of consumer credit markets using a rich and novel dataset from a large subprime auto lender. Its primary goal is to develop empirical methods for analyzing markets with asymmetric information and to use these methods to better understand the behavior of subprime borrowers and lenders. The first chapter quantifies the importance of adverse selection and moral hazard in the subprime auto loan market and shows how different loan contract terms serve to mitigate these distinct information problems. The second chapter examines the impact of centralized credit scoring on lending outcomes, including the distribution of performance across dealerships within the firm. The third chapter studies borrower repayment behavior and quantifies the impact of ex post moral hazard on interest rates and the costs of default. Collectively, the three chapters provide a better understanding of the functioning of markets for subprime credit in the U.S. They also provide unique empirical evidence on the importance of asymmetric information and the value of screening, monitoring, and contract design in consumer credit markets in general.

Book excerpt: Named one of the most important nonfiction books of the 21st century by Entertainment Weekly‚ Slate‚ Chronicle of Higher Education‚ Literary Hub, Book Riot‚ and Zora A tenth-anniversary edition of the iconic bestseller—"one of the most influential books of the past 20 years," according to the Chronicle of Higher Education—with a new preface by the author "It is in no small part thanks to Alexander's account that civil rights organizations such as Black Lives Matter have focused so much of their energy on the criminal justice system." —Adam Shatz, London Review of Books Seldom does a book have the impact of Michelle Alexander's The New Jim Crow. Since it was first published in 2010, it has been cited in judicial decisions and has been adopted in campus-wide and community-wide reads; it helped inspire the creation of the Marshall Project and the new $100 million Art for Justice Fund; it has been the winner of numerous prizes, including the prestigious NAACP Image Award; and it has spent nearly 250 weeks on the New York Times bestseller list. Most important of all, it has spawned a whole generation of criminal justice reform activists and organizations motivated by Michelle Alexander's unforgettable argument that "we have not ended racial caste in America; we have merely redesigned it." As the Birmingham News proclaimed, it is "undoubtedly the most important book published in this century about the U.S." Now, ten years after it was first published, The New Press is proud to issue a tenth-anniversary edition with a new preface by Michelle Alexander that discusses the impact the book has had and the state of the criminal justice reform movement today.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of essays is dedicated to a recently deceased philosopher and humanist, Nalin Ranasinghe. His central philosophical and humanistic preoccupation was with the human soul. Not surprisingly, his greatest inspiration was Socrates’ credo “Care for your soul,” and the title of his first book was 'The Soul of Socrates'. In this and his later writings, Ranasinghe expressed his growing concern over the idea that the human soul has been highjacked due to the way our civilization has developed: the highest and noblest aspirations of our civilization have been replaced by our obsession with money, pleasure, and power. We now live in a time where we do not know who we are, nor who the people around us are. Despite all of the technical gadgets connecting us virtually, this is the age of disconnect and loneliness, as well as of the degradations of humanity. Ranasinghe insisted that the two keys for recovery are the self-knowledge of the soul and a continuous dialogue with others. We need to relearn how to relate to ourselves and others as unique individuals, not as objects for the satisfaction of our needs. Following his ideas, the twenty essays presented here are divided into two parts: “the soul in reflection” and “the soul in dialogue.” The contributors come from various countries around the globe and work in different disciplines, and their chapters aim to revive our interest in the soul and the obscured core of our humanity. This book will appeal to undergraduate and graduate students of philosophy; however, the essays are written in a non-technical language, also making them accessible to the general audience.
