How to make European pensions adequate and sustainable?


Book Description

Presents the results of the research project on Adequacy and Sustainability of Old Age Income in the EU (AIM). Examines the differences among EU member States when it comes to saving for retirement. Suggests that while in some countries the working age population is able to sustain their consumption on retirement, in others there ia a significant saving gap.




Empirical Asset Pricing


Book Description

An introduction to the theory and methods of empirical asset pricing, integrating classical foundations with recent developments. This book offers a comprehensive advanced introduction to asset pricing, the study of models for the prices and returns of various securities. The focus is empirical, emphasizing how the models relate to the data. The book offers a uniquely integrated treatment, combining classical foundations with more recent developments in the literature and relating some of the material to applications in investment management. It covers the theory of empirical asset pricing, the main empirical methods, and a range of applied topics. The book introduces the theory of empirical asset pricing through three main paradigms: mean variance analysis, stochastic discount factors, and beta pricing models. It describes empirical methods, beginning with the generalized method of moments (GMM) and viewing other methods as special cases of GMM; offers a comprehensive review of fund performance evaluation; and presents selected applied topics, including a substantial chapter on predictability in asset markets that covers predicting the level of returns, volatility and higher moments, and predicting cross-sectional differences in returns. Other chapters cover production-based asset pricing, long-run risk models, the Campbell-Shiller approximation, the debate on covariance versus characteristics, and the relation of volatility to the cross-section of stock returns. An extensive reference section captures the current state of the field. The book is intended for use by graduate students in finance and economics; it can also serve as a reference for professionals.




Retirement Decisions


Book Description

The first wave of the 78 million member baby boom generation is now reaching retirement age. The number of people age 62, the earliest age of eligibility for Social Security retired worker benefits, is expected to be 21 percent higher in 2009 than in 2008. In addition, by 2030, the number of workers supporting each retiree is projected to be 2.2, down from 3.3 in 2006. This demographic shift poses challenges to the economy, federal tax revenues, the nation's old-age programs, and individuals' financial security in retirement. For those who are able to work longer, later retirement can strengthen the economy and also retiree incomes by postponing the time at which people will start drawing retirement benefits rather than working. A wide range of factors including the features of employers' benefit plans, personal finances, social norms, health, and individual attitudes influence workers' decisions about when to retire. Federal policies may also play a role: these include Social Security, Medicare, and tax policies related to certain private retiree health and defined benefit (DB) and defined contribution (DC) pension plans.1 Identifying both the incentives posed by these policies and the extent to which workers respond to them can help to inform policy makers as they consider ways to address the demographic challenges facing the nation. To determine the extent to which federal policiesdirectly and indirectly-pose incentives and are influencing individuals decisions about the age at which they retire, the authors have pursued the following questions: (1) What incentives do federal policies provide about when to retire? (2) What are the recent retirement patterns, and is there evidence that recent changes in Social Security requirements have resulted in later retirements? (3) Is there evidence that tax-favored private retiree health insurance and pension benefits have influenced when people retire? This is a revised and excerpted version.




Discrete Choice Methods with Simulation


Book Description

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.




Social Science Research


Book Description

This book is designed to introduce doctoral and graduate students to the process of conducting scientific research in the social sciences, business, education, public health, and related disciplines. It is a one-stop, comprehensive, and compact source for foundational concepts in behavioral research, and can serve as a stand-alone text or as a supplement to research readings in any doctoral seminar or research methods class. This book is currently used as a research text at universities on six continents and will shortly be available in nine different languages.




The Derivatives Sourcebook


Book Description

The Derivatives Sourcebook is a citation study and classification system that organizes the many strands of the derivatives literature and assigns each citation to a category. Over 1800 research articles are collected and organized into a simple web-based searchable database. We have also included the 1997 Nobel lectures of Robert Merton and Myron Scholes as a backdrop to this literature.




The Measurement of Environmental and Resource Values


Book Description

Non-market valuation is becoming increasingly accepted as an evaluative tool of economics related to environmental and resource protection. Freeman (economics, Bowdoin College) presents an overview of the literature, introducing the principal methods and techniques of resource valuation. Chapters cover the measurement of welfare changes, revealed and stated preference models, nonuse models, aggregation of values across time, environmental quality as factor input, longevity and health valuation, property value models, hedonic wage models, and recreational uses of natural resource systems.

Introduction to Information Retrieval


Book Description

Class-tested and coherent, this textbook teaches classical and web information retrieval, including web search and the related areas of text classification and text clustering from basic concepts. It gives an up-to-date treatment of all aspects of the design and implementation of systems for gathering, indexing, and searching documents; methods for evaluating systems; and an introduction to the use of machine learning methods on text collections. All the important ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students in computer science. Based on feedback from extensive classroom experience, the book has been carefully structured in order to make teaching more natural and effective. Slides and additional exercises (with solutions for lecturers) are also available through the book's supporting website to help course instructors prepare their lectures.
