This book was released on 2013-02-21 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This User’s Guide is a resource for investigators and stakeholders who develop and review observational comparative effectiveness research protocols. It explains how to (1) identify key considerations and best practices for research design; (2) build a protocol based on these standards and best practices; and (3) judge the adequacy and completeness of a protocol. Eleven chapters cover all aspects of research design, including: developing study objectives, defining and refining study questions, addressing the heterogeneity of treatment effect, characterizing exposure, selecting a comparator, defining and measuring outcomes, and identifying optimal data sources. Checklists of guidance and key considerations for protocols are provided at the end of each chapter. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews. More more information, please consult the Agency website: www.effectivehealthcare.ahrq.gov)
Book Synopsis Migration, Search and Skill Heterogeneity by : Myrto Oikonomou
Download or read book Migration, Search and Skill Heterogeneity written by Myrto Oikonomou and published by International Monetary Fund. This book was released on 2023-06-30 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cross-border migration can act as an important adjustment mechanism to country-specific shocks. Yet, depending on who moves, it can have unintended consequences for business cycle stability. This paper argues that the skill composition of migration plays a critical role. When migration flows become more concentrated in skilled labor an important trade-off arises. On the one hand, migration releases unemployment pressures for the origin countries. On the other hand, it generates negative compositional effects (the so-called “brain drain” effects) and skill imbalances, which reduce supply capacity in origin countries. This paper analyses quantitatively the impact of cyclical migration in an open-economy Dynamic Stochastic General Equilibrium (DSGE) model with endogenous migration flows, trade linkages, search and matching frictions, and skill heterogeneity. I apply this framework to the case of the Greek emigration wave following the European Debt Crisis. What I find is that emigration flows implied strong negative effects for capital formation, leading to more than a 15 percentage point drop in investment. Rather than stabilizing the Greek business cycle, labor mobility led to a deeper and more protracted recession.

Book Synopsis Heterogeneity and Persistence in Returns to Wealth by : Andreas Fagereng
Download or read book Heterogeneity and Persistence in Returns to Wealth written by Andreas Fagereng and published by International Monetary Fund. This book was released on 2018-07-27 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: We provide a systematic analysis of the properties of individual returns to wealth using twelve years of population data from Norway’s administrative tax records. We document a number of novel results. First, during our sample period individuals earn markedly different average returns on their financial assets (a standard deviation of 14%) and on their net worth (a standard deviation of 8%). Second, heterogeneity in returns does not arise merely from differences in the allocation of wealth between safe and risky assets: returns are heterogeneous even within asset classes. Third, returns are positively correlated with wealth: moving from the 10th to the 90th percentile of the financial wealth distribution increases the return by 3 percentage points - and by 17 percentage points when the same exercise is performed for the return to net worth. Fourth, wealth returns exhibit substantial persistence over time. We argue that while this persistence partly reflects stable differences in risk exposure and assets scale, it also reflects persistent heterogeneity in sophistication and financial information, as well as entrepreneurial talent. Finally, wealth returns are (mildly) correlated across generations. We discuss the implications of these findings for several strands of the wealth inequality debate.
Book Synopsis Labor in the New Economy by : Katharine G. Abraham
Download or read book Labor in the New Economy written by Katharine G. Abraham and published by University of Chicago Press. This book was released on 2010-11-15 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the structure of the economy has changed over the past few decades, researchers and policy makers have been increasingly concerned with how these changes affect workers. In this book, leading economists examine a variety of important trends in the new economy, including inequality of earnings and other forms of compensation, job security, employer reliance on temporary and contract workers, hours of work, and workplace safety and health. In order to better understand these vital issues, scholars must be able to accurately measure labor market activity. Thus, Labor in the New Economy also addresses a host of measurement issues: from the treatment of outliers, imputation methods, and weighting in the context of specific surveys to evaluating the strengths and weaknesses of data from different sources. At a time when employment is a central concern for individuals, businesses, and the government, this volume provides important insight into the recent past and will be a useful tool for researchers in the future.
Book Synopsis Search Theory and Unemployment by : Stephen A. Woodbury
Download or read book Search Theory and Unemployment written by Stephen A. Woodbury and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Search Theory and Unemployment contains nine chapters that survey and extend the theory of job search and its application to the problem of unemployment. The volume ranges from surveys of job search theory that take microeconomic and macroeconomic perspectives to original theoretical contributions which focus on the externalities arising from non-sequential search and search under imperfect information. It includes a clear and authoritative survey of econometric methods that have been developed to estimate models of job search, as well as two lucid contributions to the empirical search literature. Finally, it includes a study that reviews and extends the literature on optimal unemployment insurance and concludes with an appraisal of the influence of search theory on the thinking of macroeconomic policymakers.
Book Synopsis Ontology Matching by : Jérôme Euzenat
Download or read book Ontology Matching written by Jérôme Euzenat and published by Springer Science & Business Media. This book was released on 2007-06-15 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ontologies are viewed as the silver bullet for many applications, but in open or evolving systems, different parties can adopt different ontologies. This increases heterogeneity problems rather than reducing heterogeneity. This book proposes ontology matching as a solution to the problem of semantic heterogeneity, offering researchers and practitioners a uniform framework of reference to currently available work. The techniques presented apply to database schema matching, catalog integration, XML schema matching and more.
Book Synopsis Spatial Dependence and Heterogeneity in Empirical Analyses of Regional Labour Market Dynamics by : Norbert Schanne
Download or read book Spatial Dependence and Heterogeneity in Empirical Analyses of Regional Labour Market Dynamics written by Norbert Schanne and published by wbv Media GmbH & Company KG. This book was released on 2015-06-23 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warum sollen Regionen innerhalb eines Landes unabhängige Inseln sein? Und warum sollen, über das gesamte Land hinweg, einheitlich starke ökonomische oder soziale Wirkungszusammenhänge bestehen? Diese zwei Annahmen werden in der angewandten empirischen Wirtschafts- und Sozialforschung üblicherweise implizit unterstellt. Wie in statistischen Verfahren von dieser unrealistischen Modellstruktur unter Ausnutzung der räumlichen Strukturen in beobachteten Variablen und unterstellten Zusammenhängen abgewichen werden kann, diskutiert Norbert Schanne im vorliegenden Band. Möglichkeiten, unser Verständnis der Ökonomie zu vertiefen, werden ebenso verdeutlicht, wie Chancen und Tücken beim Einsatz der Methoden in Studien zu verschiedenen Aspekten der Arbeitsmarktdynamik.

Book Synopsis Search Externalities in Firm-to-Firm Trade by : John Spray
Download or read book Search Externalities in Firm-to-Firm Trade written by John Spray and published by International Monetary Fund. This book was released on 2021-03-19 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: I develop a model of firm-to-firm search and matching to show that the impact of falling trade costs on firm sourcing decisions and consumer welfare depends on the relative size of search externalities in domestic and international markets. These externalities can be positive if firms share information about potential matches, or negative if the market is congested. Using unique firm-to-firm transaction-level data from Uganda, I document empirical evidence consistent with positive externalities in international markets and negative externalities in domestic markets. I then build a dynamic quantitative version of the model and show that, in Uganda, a 25% reduction in trade costs led to a 3.7% increase in consumer welfare, 12% of which was due to search externalities.
Book Synopsis Attention and Performance XVI by : Daniel Gopher
Download or read book Attention and Performance XVI written by Daniel Gopher and published by MIT Press. This book was released on 1996 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributions to this volume, the sixteenth in the prestigious Attention and Performance series, revisit the issue of modularity, the idea that many functions are independently realized in specialized, autonomous modules. Although there is much evidence of modularity in the brain, there is also reason to believe that the outcome of processing, across domains, depends on the synthesis of a wide range of constraining influences. The twenty-four chapters in Attention and Performance XVI look at how these influences are integrated in perception, attention, language comprehension, and motor control. They consider the mechanisms of information integration in the brain; examine the status of the modularity hypothesis in light of efforts to understand how information integration can be successfully achieved; and discuss information integration from the viewpoints of psychophysics, physiology, and computational theory.

This stimulating book is an essential reference for practitioners engaged in data science and business intelligence, and for researchers specializing in taxonomy matching and semantic similarity assessment. The work is also suitable as a supplementary text for advanced undergraduate and postgraduate courses on information and metadata management.
Book Synopsis Matching with Transfers by : Pierre-André Chiappori
Download or read book Matching with Transfers written by Pierre-André Chiappori and published by Princeton University Press. This book was released on 2020-05-26 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, matching models, which use mathematical frameworks to analyze allocation mechanisms for heterogeneous products and individuals, have attracted renewed attention in both theoretical and applied economics. These models have been used in many contexts, from labor markets to organ donations, but recent work has tended to focus on "nontransferable" cases rather than matching models with transfers. In this important book, Pierre-André Chiappori fills a gap in the literature by presenting a clear and elegant overview of matching with transfers and provides a set of tools that enable the analysis of matching patterns in equilibrium, as well as a series of extensions. He then applies these tools to the field of family economics and shows how analysis of matching patterns and of the incentives thus generated can contribute to our understanding of long-term economic trends, including inequality and the demand for higher education.

Download or read book Uberland written by Alex Rosenblat and published by Univ of California Press. This book was released on 2018-10-23 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon Valley technology is transforming the way we work, and Uber is leading the charge. An American startup that promised to deliver entrepreneurship for the masses through its technology, Uber instead built a new template for employment using algorithms and Internet platforms. Upending our understanding of work in the digital age, Uberland paints a future where any of us might be managed by a faceless boss. The neutral language of technology masks the powerful influence algorithms have across the New Economy. Uberland chronicles the stories of drivers in more than twenty-five cities in the United States and Canada over four years, shedding light on their working conditions and providing a window into how they feel behind the wheel. The book also explores Uber’s outsized influence around the world: the billion-dollar company is now influencing everything from debates about sexual harassment and transportation regulations to racial equality campaigns and labor rights initiatives. Based on award-winning technology ethnographer Alex Rosenblat’s firsthand experience of riding over 5,000 miles with Uber drivers, daily visits to online forums, and face-to-face discussions with senior Uber employees, Uberland goes beyond the headlines to reveal the complicated politics of popular technologies that are manipulating both workers and consumers.
Book Synopsis Discrete Choice Methods with Simulation by : Kenneth Train
Download or read book Discrete Choice Methods with Simulation written by Kenneth Train and published by Cambridge University Press. This book was released on 2009-07-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the new generation of discrete choice methods, focusing on the many advances that are made possible by simulation. Researchers use these statistical methods to examine the choices that consumers, households, firms, and other agents make. Each of the major models is covered: logit, generalized extreme value, or GEV (including nested and cross-nested logits), probit, and mixed logit, plus a variety of specifications that build on these basics. Simulation-assisted estimation procedures are investigated and compared, including maximum stimulated likelihood, method of simulated moments, and method of simulated scores. Procedures for drawing from densities are described, including variance reduction techniques such as anithetics and Halton draws. Recent advances in Bayesian procedures are explored, including the use of the Metropolis-Hastings algorithm and its variant Gibbs sampling. The second edition adds chapters on endogeneity and expectation-maximization (EM) algorithms. No other book incorporates all these fields, which have arisen in the past 25 years. The procedures are applicable in many fields, including energy, transportation, environmental studies, health, labor, and marketing.
