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.

We show that “preemptive” capital flow management measures (CFM) can reduce emerging markets and developing countries’ (EMDE) external finance premia during risk-off shocks, especially for vulnerable countries. Using a panel dataset of 56 EMDEs during 1996–2020 at monthly frequency, we document that countries with preemptive policies in place during the five year window before risk-off shocks experienced relatively lower external finance premia and exchange rate volatility during the shock compared to countries which did not have such preemptive policies in place. We use the episodes of Taper Tantrum and COVID-19 as risk-off shocks. Our identification relies on a difference-in-differences methodology with country fixed effects where preemptive policies are ex-ante by construction and cannot be put in place as a response to the shock ex-post. We control the effects of other policies, such as monetary policy, foreign exchange interventions (FXI), easing of inflow CFMs and tightening of outflow CFMs that are used in response to the risk-off shocks. By reducing the impact of risk-off shocks on countries’ funding costs and exchange rate volatility, preemptive policies enable countries’ continued access to international capital markets during troubled times.

In Lifecycle Events and Their Consequences: Job Loss, Family Change, and Declines in Health, editors Kenneth A. Couch, Mary C. Daly, and Julie Zissimopoulos bring together leading scholars to study the impact of unexpected life course events on economic welfare. The contributions in this volume explore how job loss, the onset of health limitations, and changes in household structure can have a pronounced influence on individual and household well-being across the life course. Although these events are typically studied in isolation, they frequently co-occur or are otherwise interrelated. This book provides a systematic empirical overview of these sometimes uncertain events and their impact. By placing them in a unified analytical framework and approaching each of them from a similar perspective, Lifecycle Events and Their Consequences illustrates the importance of a coherent approach to thinking about the inter-relationships among these shifts. Finally, this volume aims to set the future research agenda in this important area.

This paper explores the effect of news shocks on the current account and other macroeconomic variables using worldwide giant oil discoveries as a directly observable measure of news shocks about future output ? the delay between a discovery and production is on average 4 to 6 years. We first present a two-sector small open economy model in order to predict the responses of macroeconomic aggregates to news of an oil discovery. We then estimate the effects of giant oil discoveries on a large panel of countries. Our empirical estimates are consistent with the predictions of the model. After an oil discovery, the current account and saving rate decline for the first 5 years and then rise sharply during the ensuing years. Investment rises robustly soon after the news arrives, while GDP does not increase until after 5 years. Employment rates fall slightly for a sustained period of time.

The essential reference for human development theory, updated and reconceptualized The Handbook of Child Psychology and Developmental Science, a four-volume reference, is the field-defining work to which all others are compared. First published in 1946, and now in its Seventh Edition, the Handbook has long been considered the definitive guide to the field of developmental science. Volume 4: Ecological Settings and Processes in Developmental Systems is centrally concerned with the people, conditions, and events outside individuals that affect children and their development. To understand children's development it is both necessary and desirable to embrace all of these social and physical contexts. Guided by the relational developmental systems metatheory, the chapters in the volume are ordered them in a manner that begins with the near proximal contexts in which children find themselves and moving through to distal contexts that influence children in equally compelling, if less immediately manifest, ways. The volume emphasizes that the child's environment is complex, multi-dimensional, and structurally organized into interlinked contexts; children actively contribute to their development; the child and the environment are inextricably linked, and contributions of both child and environment are essential to explain or understand development. Understand the role of parents, other family members, peers, and other adults (teachers, coaches, mentors) in a child's development Discover the key neighborhood/community and institutional settings of human development Examine the role of activities, work, and media in child and adolescent development Learn about the role of medicine, law, government, war and disaster, culture, and history in contributing to the processes of human development The scholarship within this volume and, as well, across the four volumes of this edition, illustrate that developmental science is in the midst of a very exciting period. There is a paradigm shift that involves increasingly greater understanding of how to describe, explain, and optimize the course of human life for diverse individuals living within diverse contexts. This Handbook is the definitive reference for educators, policy-makers, researchers, students, and practitioners in human development, psychology, sociology, anthropology, and neuroscience.

Evidence indicates that actions within four main themes (early child development fair employment and decent work social protection and the living environment) are likely to have the greatest impact on the social determinants of health and health inequities. A systematic search and analysis of recommendations and policy guidelines from intergovernmental organizations and international bodies identified practical policy options for action on social determinants within these four themes. Policy options focused on early childhood education and care; child poverty; investment strategies for an inclusive economy; active labour market programmes; working conditions; social cash transfers; affordable housing; and planning and regulatory mechanisms to improve air quality and mitigate climate change. Applying combinations of these policy options alongside effective governance for health equity should enable WHO European Region Member States to reduce health inequities and synergize efforts to achieve the United Nations Sustainable Development Goals.

Lawrence H. Summers presents a new paradigm for thinking about the current economic and technological revolution We are buffeted by the sense that everything is accelerating: Digital technology is changing the way we work, shop, and socialize. And yet for all the talk about disruptive innovations, economic growth is largely stagnant. We are told that with new technologies average citizens are empowered as never before, and yet wide swaths of the population feel powerless and can no longer count on stable careers and a better life for their children. As Lawrence H. Summers shows in The Post-Widget Society, these are the paradoxes that define the economic revolution that is transforming our world. At the heart of this revolution are two dramatic developments in Western economies: the declining significance of widgets (mass-produced goods) and the rise of design goods (products that cost a lot to design but little to produce); and the controversial prospect of secular stagnation, the long-term phenomenon of negligible economic growth and depressed employment in a dynamic market economy. Summers’s trenchant analysis of these trends reveals that they have profound implications not only for the future of jobs and widening income inequality but also for the nature of the state and the very stability of society. A bold, pathbreaking book by one of our most important economists, The Post-Widget Society is necessary reading for every American concerned about our economic and political future.

Addressing the challenge of covering heath care expenses—while minimizing economic risks. Moral hazard—the tendency to change behavior when the cost of that behavior will be borne by others—is a particularly tricky question when considering health care. Kenneth J. Arrow’s seminal 1963 paper on this topic (included in this volume) was one of the first to explore the implication of moral hazard for health care, and Amy Finkelstein—recognized as one of the world’s foremost experts on the topic—here examines this issue in the context of contemporary American health care policy. Drawing on research from both the original RAND Health Insurance Experiment and her own research, including a 2008 Health Insurance Experiment in Oregon, Finkelstein presents compelling evidence that health insurance does indeed affect medical spending and encourages policy solutions that acknowledge and account for this. The volume also features commentaries and insights from other renowned economists, including an introduction by Joseph P. Newhouse that provides context for the discussion, a commentary from Jonathan Gruber that considers provider-side moral hazard, and reflections from Joseph E. Stiglitz and Kenneth J. Arrow. “Reads like a fireside chat among a group of distinguished, articulate health economists.” —Choice
