Available in PDF, EPUB and Kindle. Book excerpt: In this paper we argue that once one departs from the simple classroom example, or `stripped down life-cycle model, ' the empirical model for consumption growth can be made flexible enough to fit the main features of the data. More specifically, we show that allowing demographics to affect household preferences and relaxing the assumption of certainty equivalence can generate hump-shaped consumption profiles over age that are very similar to those observed in household-level data sources, without appealing to alternative explanations (such as liquidity constraints, myopia or mental accounting). The hump-shape is partly attributable to precautionary savings, and partly due to demographics; the tracking (whereby consumption jumps with income) is instead due to the permanent nature of the income shocks. We use US household-level data to estimate preference parameters and income profiles, and then simulate consumption profiles for different education groups. Our simulated profiles show that the key features observed in the data can be closely matched in simulation. We also show that neglecting uncertainty produces consumption profiles that are `too flat, ' whereas neglecting demographics generates consumption profiles that peak `too late.'
Book Synopsis The Economics of Consumption by : Tullio Jappelli
Download or read book The Economics of Consumption written by Tullio Jappelli and published by Oxford University Press. This book was released on 2017-09-01 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consumption decisions are crucial determinants of business cycles and growth. Knowledge of how consumers respond to the economic environment and how they react to the risks that they encounter during the life-cycle is therefore important for evaluating stabilization policies and the effectiveness of fiscal packages implemented in response to economic downturns or financial crises. In The Economics of Consumption, Tullio Jappelli and Luigi Pistaferri provide a comprehensive examination of the most important developments in the field of consumption decisions and evaluate economic models against empirical evidence. The first part of the book provides the basic ingredients of economic models of consumption decisions. The central part reviews the empirical literature on the effect of income and wealth changes on consumption and on the relevance of precautionary saving and credit market imperfections. The last chapters extend the basic framework to such important areas as bequests, leisure, lifetime uncertainty, and financial sophistication. Jappelli and Pistaferri shed light on important issues, including how consumption responds to changes in economic resources, how economic circumstances and consumers' characteristics influence behavior, and whether consumption inequality depends on income shocks and their persistence.
Book Synopsis The Limits of Choice by : Sahra Wagenknecht
Download or read book The Limits of Choice written by Sahra Wagenknecht and published by Campus Verlag. This book was released on 2013-10-02 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wann und warum sparen private Haushalte? Sahra Wagenknecht untersucht in ihrer Dissertation den Zusammenhang von Sparentscheidungen und Grundbedürfnissen in Deutschland und den USA von den 1950er-Jahren bis heute. Ihre zentrale Hypothese lautet, dass der Einkommensanteil der Ausgaben zur Befriedigung von Grundbedürfnissen die entscheidende Erklärungsvariable des individuellen Sparverhaltens darstellt. In Abgrenzung zur Lebenszyklus- bzw. Permanenten Einkommenshypothese (LCPIH) kann Wagenknecht zeigen, dass die individuelle Sparquote entscheidend vom langfristigen Einkommen abhängt. Die Arbeit weist für einen Zeitraum von über 50 Jahren nach, dass sich auch auf volkswirtschaftlicher Ebene die Veränderung der privaten Sparquote durch den "necessity share" erklären lässt. Das vorgelegte Modell liefert zudem eine Erklärung, weshalb die private Sparquote bei steigender Einkommensungleichheit in Volkswirtschaften mit dereguliertem Kreditmarkt sinkt, während sie bei restriktiven Kreditmärkten steigt.
Book Synopsis Consumer Demographics and Behaviour by : Jo M. Martins
Download or read book Consumer Demographics and Behaviour written by Jo M. Martins and published by Springer Science & Business Media. This book was released on 2011-11-01 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the book that market strategists have been waiting for to position themselves in global markets and take advantage of the opportunities that demographic bonuses and deficits offer to them and their products. It is also a book for teachers and students of consumer behaviour to grasp the importance of the life cycle as a framework that shapes the demand for goods and services determined by changes in social, economic and physical functioning. It gives insights into gendered consumer behaviour and cohort effects. It presents a range of views on consumer behaviour and how demographic perspectives enhance these perspectives. The book offers conceptual and analytical tools that can be used in the assessment of population characteristics as determinants of market size, composition and potential for a variety of products. It offers organising frameworks as well as empirical evidence of consumer behaviour in clusters of markets, with different rates of population growth and age distribution that affect consumers’ priorities and demand for basic and progressive commodities. The book shows commonalities as well as differences in consumer behaviour arising from different cultures and social customs. It uses analytical tools that are explained and accessible to readers with a range of competences. It is a book that can give a better understanding of consumer behaviour and market opportunities to the practitioner. It can also be used for the instruction of students in demography, consumer behaviour and marketing.
Book Synopsis Theory of Macroeconomic Policy by : Christopher Tsoukis
Download or read book Theory of Macroeconomic Policy written by Christopher Tsoukis and published by Oxford University Press. This book was released on 2020-10-22 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theory of Macroeconomic Policy reviews the theoretical foundations of macroeconomic, fiscal, and monetary, policy. It offers a panoramic view of macroeconomic theory, covering a wide range of topics that are not customarily dealt with in macroeconomics texts, as well as more standard material. Advanced theory is bridged with more elementary or intermediate material, and established models are reviewed alongside current research directions. There is an extensive review of empirical evidence on virtually every topic, supplemented by narrative accounts for various episodes. The policy implications of the various theories are emphasised throughout. The chapters are largely self-contained so that different courses can focus at different places. A 'Guidance for Further Study' Section and extensive bibliography give plenty of ideas for all levels of independent study, from Undergraduate Projects to MSc Dissertations to PhD Theses. Theory of Macroeconomic Policy presents a balance between: breadth as well as depth; analytical treatment and intuition; theory and evidence; vintage theories and current directions; theory and policy; (established) theory and debate. Theory of Macroeconomic Policy is an affirmation that there is a well-developed body of theory that is invaluable for an in-depth understanding of the macro-economy and policy; equally, there is much scope for critical discussion and debate.
Book Synopsis Measuring What We Spend by : National Research Council
Download or read book Measuring What We Spend written by National Research Council and published by National Academies Press. This book was released on 2013-03-15 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Consumer Expenditure (CE) surveys are the only source of information on the complete range of consumers' expenditures and incomes in the United States, as well as the characteristics of those consumers. The CE consists of two separate surveys: (1) a national sample of households interviewed five times at three-month intervals; and (2) a separate national sample of households that complete two consecutive one-week expenditure diaries. For more than 40 years, these surveys, the responsibility of the Bureau of Labor Statistics (BLS), have been the principal source of knowledge about changing patterns of consumer spending in the U.S. population. In February 2009, BLS initiated the Gemini Project, the aim of which is to redesign the CE surveys to improve data quality through a verifiable reduction in measurement error with a particular focus on underreporting. The Gemini Project initiated a series of information-gathering meetings, conference sessions, forums, and workshops to identify appropriate strategies for improving CE data quality. As part of this effort, BLS requested the National Research Council's Committee on National Statistics (CNSTAT) to convene an expert panel to build on the Gemini Project by conducting further investigations and proposing redesign options for the CE surveys. The charge to the Panel on Redesigning the BLS Consumer Expenditure Surveys includes reviewing the output of a Gemini-convened data user needs forum and methods workshop and convening its own household survey producers workshop to obtain further input. In addition, the panel was tasked to commission options from contractors for consideration in recommending possible redesigns. The panel was further asked by BLS to create potential redesigns that would put a greater emphasis on proactive data collection to improve the measurement of consumer expenditures. Measuring What We Spend summarizes the deliberations and activities of the panel, discusses the conclusions about the uses of the CE surveys and why a redesign is needed, as well as recommendations for the future.
Book Synopsis Consumption Over the Life Cycle by : Pierre-Olivier Gourinchas
Download or read book Consumption Over the Life Cycle written by Pierre-Olivier Gourinchas and published by . This book was released on 1999 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper employs a synthetic cohort technique and Consumer Expenditure Survey data to construct average age-profiles of consumption and income over the working lives of typical households across different education and occupation groups. Using these profiles, we estimate a structural model of optimal life-cycle consumption expenditures in the presence of realistic labor income uncertainty. The model fits the profiles quite well. In addition to providing tight estimates of the discount rate and risk aversion, we find that consumer behavior changes strikingly over the life-cycle. Young consumers behave as buffer-stock agents. Around age 40, the typical household starts accumulating liquid assets for retirement, and its behavior mimics more closely that of a certainty equivalent consumer. This change in behavior is mostly driven by the life-cycle profile of expected income. Our methodology provides a natural decomposition of saving into its precautionary and retirement components.

Book Synopsis The New Financial Order by : Robert J. Shiller
Download or read book The New Financial Order written by Robert J. Shiller and published by Princeton University Press. This book was released on 2009-02-09 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his best-selling Irrational Exuberance, Robert Shiller cautioned that society's obsession with the stock market was fueling the volatility that has since made a roller coaster of the financial system. Less noted was Shiller's admonition that our infatuation with the stock market distracts us from more durable economic prospects. These lie in the hidden potential of real assets, such as income from our livelihoods and homes. But these ''ordinary riches,'' so fundamental to our well-being, are increasingly exposed to the pervasive risks of a rapidly changing global economy. This compelling and important new book presents a fresh vision for hedging risk and securing our economic future. Shiller describes six fundamental ideas for using modern information technology and advanced financial theory to temper basic risks that have been ignored by risk management institutions--risks to the value of our jobs and our homes, to the vitality of our communities, and to the very stability of national economies. Informed by a comprehensive risk information database, this new financial order would include global markets for trading risks and exploiting myriad new financial opportunities, from inequality insurance to intergenerational social security. Just as developments in insuring risks to life, health, and catastrophe have given us a quality of life unimaginable a century ago, so Shiller's plan for securing crucial assets promises to substantially enrich our condition. Once again providing an enormous service, Shiller gives us a powerful means to convert our ordinary riches into a level of economic security, equity, and growth never before seen. And once again, what Robert Shiller says should be read and heeded by anyone with a stake in the economy.
Book Synopsis Population Matters by : Nancy Birdsall
Download or read book Population Matters written by Nancy Birdsall and published by Oxford University Press. This book was released on 2001 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of demography on economic performance has been the subject of intense debate in economics for nearly two centuries. In recent years opinion has swung between the Malthusian views of Coale and Hoover, and the cornucopian views of Julian Simon. Unfortunately, until recently, data weretoo weak and analytical models too limited to provide clear insights into the relationship. As a result, economists as a group have not been clear or conclusive.This volume, which is based on a collection of papers that heavily rely on data from the 1980s and 1990s and on new analytical approaches, sheds important new light on demographic--economic relationships, and it provides clearer policy conclusions than any recent work on the subject. In particular,evidence from developing countries throughout the world shows a pattern in recent decades that was not evident earlier: countries with higher rates of population growth have tended to see less economic growth. An analysis of the role of demography in the "Asian economic miracle" strongly suggeststhat changes in age structures resulting from declining fertility create a one-time "demographic gift" or window of opportunity, when the working age population has relatively few dependants, of either young or old age, to support. Countries which recognize and seize on this opportunity can, as theAsian tigers did, realize healthy bursts in economic output. But such results are by no means assured: only for countries with otherwise sound economic policies will the window of opportunity yield such dramatic results. Finally, several of the studies demonstrate the likelihood of a causalrelationship between high fertility and poverty. While the direction of causality is not always clear and very likely is reciprocal (poverty contributes to high fertility and high fertility reinforces poverty), the studies support the view that lower fertility at the country level helps create apath out of poverty for many families.Population Matters represents an important further step in our understanding of the contribution of population change to economic performance. As such, it will be a useful volume for policymakers both in developing countries and in international development agencies.
Book Synopsis Forward-Looking Decision Making by : Robert E. Hall
Download or read book Forward-Looking Decision Making written by Robert E. Hall and published by Princeton University Press. This book was released on 2010-02-08 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Individuals and families make key decisions that impact many aspects of financial stability and determine the future of the economy. These decisions involve balancing current sacrifice against future benefits. People have to decide how much to invest in health care, exercise, their diet, and insurance. They must decide how much debt to take on, and how much to save. And they make choices about jobs that determine employment and unemployment levels. Forward-Looking Decision Making is about modeling this individual or family-based decision making using an optimizing dynamic programming model. Robert Hall first reviews ideas about dynamic programs and introduces new ideas about numerical solutions and the representation of solved models as Markov processes. He surveys recent research on the parameters of preferences--the intertemporal elasticity of substitution, the Frisch elasticity of labor supply, and the Frisch cross-elasticity. He then examines dynamic programming models applied to health spending, long-term care insurance, employment, entrepreneurial risk-taking, and consumer debt. Linking theory with data and applying them to real-world problems, Forward-Looking Decision Making uses dynamic optimization programming models to shed light on individual behaviors and their economic implications.

Download or read book Handbook of Econometrics written by James Joseph Heckman and published by Elsevier. This book was released on 2007 with total page 1013 pages. Available in PDF, EPUB and Kindle. Book excerpt: As conceived by the founders of the Econometric Society, econometrics is a field that uses economic theory and statistical methods to address empirical problems in economics. It is a tool for empirical discovery and policy analysis. The chapters in this volume embody this vision and either implement it directly or provide the tools for doing so. This vision is not shared by those who view econometrics as a branch of statistics rather than as a distinct field of knowledge that designs methods of inference from data based on models of human choice ...
Download or read book Dynamic Economics written by Jerome Adda and published by MIT Press. This book was released on 2023-05-09 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated approach to the empirical application of dynamic optimization programming models, for students and researchers. This book is an effective, concise text for students and researchers that combines the tools of dynamic programming with numerical techniques and simulation-based econometric methods. Doing so, it bridges the traditional gap between theoretical and empirical research and offers an integrated framework for studying applied problems in macroeconomics and microeconomics. In part I the authors first review the formal theory of dynamic optimization; they then present the numerical tools and econometric techniques necessary to evaluate the theoretical models. In language accessible to a reader with a limited background in econometrics, they explain most of the methods used in applied dynamic research today, from the estimation of probability in a coin flip to a complicated nonlinear stochastic structural model. These econometric techniques provide the final link between the dynamic programming problem and data. Part II is devoted to the application of dynamic programming to specific areas of applied economics, including the study of business cycles, consumption, and investment behavior. In each instance the authors present the specific optimization problem as a dynamic programming problem, characterize the optimal policy functions, estimate the parameters, and use models for policy evaluation. The original contribution of Dynamic Economics: Quantitative Methods and Applications lies in the integrated approach to the empirical application of dynamic optimization programming models. This integration shows that empirical applications actually complement the underlying theory of optimization, while dynamic programming problems provide needed structure for estimation and policy evaluation.
Book Synopsis Optimal Unemployment Insurance by : Andreas Pollak
Download or read book Optimal Unemployment Insurance written by Andreas Pollak and published by Mohr Siebeck. This book was released on 2007 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing a good unemployment insurance scheme is a delicate matter. In a system with no or little insurance, households may be subject to a high income risk, whereas excessively generous unemployment insurance systems are known to lead to high unemployment rates and are costly both from a fiscal perspective and for society as a whole. Andreas Pollak investigates what an optimal unemployment insurance system would look like, i.e. a system that constitutes the best possible compromise between income security and incentives to work. Using theoretical economic models and complex numerical simulations, he studies the effects of benefit levels and payment durations on unemployment and welfare. As the models allow for considerable heterogeneity of households, including a history-dependent labor productivity, it is possible to analyze how certain policies affect individuals in a specific age, wealth or skill group. The most important aspect of an unemployment insurance system turns out to be the benefits paid to the long-term unemployed. If this parameter is chosen too high, a large number of households may get caught in a long spell of unemployment with little chance of finding work again. Based on the predictions in these models, the so-called "Hartz IV" labor market reform recently adopted in Germany should have highly favorable effects on the unemployment rates and welfare in the long run.
Book Synopsis Unintended Effects From the Expansion of the Non-Contributory Health System in Peru by : Jose Torres
Download or read book Unintended Effects From the Expansion of the Non-Contributory Health System in Peru written by Jose Torres and published by International Monetary Fund. This book was released on 2021-04-23 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, the Peruvian government has made great efforts to improve access to health care by significantly augmenting the coverage of the non-contributory public health care system Seguro Integral de Salud (SIS). This expansion has a positive impact on welfare and public health indicators, as it limits the risk of catastrophic health-related costs for previously uninsured individuals and allows for the appropriate treatment of illnesses. However, it also entails some unintended consequences for informality, tax revenues, and GDP, since a few formal agents are paying for a service that the majority of (informal) agents receive for free. In this paper, we use a general equilibrium model calibrated for Peru to simulate the expansion of SIS to quantify the unintended effects. We find that overall welfare increases, but informality rises by 2.7 percent, while tax revenues and output decrease by roughly 0.1 percent. Given the extent of the expansion in eligibility, the economic relevance of these results seems negligible. However, this occurs because the expansion of coverage was mostly funded by reducing the spending per-insured person. In fact, we find larger costs if public spending is increased to improve the quality of service given universal coverage.
