NUDGE: IMPROVING DECISIONS ABOUT HEALTH, WEALTH, AND HAPPINESS by Richard H. Thaler and Cass R. Sunstein Penguin Books, 2009, 312 pp, ISBN 978-0-14-311526-7This book is best described formally as a general explanation of and advocacy for libertarian paternalism, a term coined by the authors in earlier publications. Informally, it is about how leaders, systems, organizations, and governments can nudge people to do the things the nudgers want and need done for the betterment of the nudgees, or of society. It is paternalism in the sense that "it is legitimate for choice architects to try to influence people's behavior in order to make their lives longer, healthier, and better", (p. 5) It is libertarian in that "people should be free to do what they like - and to opt out of undesirable arrangements if they want to do so", (p. 5) The built-in possibility of opting out or making a different choice preserves freedom of choice even though people's behavior has been influenced by the nature of the presentation of the information or by the structure of the decisionmaking system. I had never heard of libertarian paternalism before reading this book, and I now find it fascinating.Written for a general audience, this book contains mostly social and behavioral science theory and models, but there is considerable discussion of structure and process that has roots in mathematical and quantitative modeling. One of the main applications of this social system is economic choice in investing, selecting and purchasing products and services, systems of taxes, banking (mortgages, borrowing, savings), and retirement systems. Other quantitative social choice systems discussed include environmental effects, health care plans, gambling, and organ donations. Softer issues that are also subject to a nudge-based approach are marriage, education, eating, drinking, smoking, influence, spread of information, and politics. There is something in this book for everyone.The basis for this libertarian paternalism concept is in the social theory called "science of choice", the study of the design and implementation of influence systems on various kinds of people. The terms Econs and Humans, are used to refer to people with either considerable or little rational decision-making talent, respectively. The various libertarian paternalism concepts and systems presented are tested and compared in light of these two types of people. Two foundational issues that this book has in common with another book, Network of Echoes: Imitation, Innovation and Invisible Leaders, that was also reviewed for this issue of the Journal are that 1 ) there are two modes of thinking (or components of the brain) - an automatic (intuitive) process and a reflective (rational) process and 2) the need for conformity and the desire for imitation are powerful forces in human behavior. …

Multiple Imputation for Nonresponse in Surveys

We investigate conditions sufficient for identification of average treatment effects using instrumental variables. First we show that the existence of valid instruments is not sufficient to identify any meaningful average treatment effect. We then establish that the combination of an instrument and a condition on the relation between the instrument and the participation status is sufficient for identification of a local average treatment effect for those who can be induced to change their participation status by changing the value of the instrument. Finally we derive the probability limit of the standard IV estimator under these conditions. It is seen to be a weighted average of local average treatment effects.

Evolution and Rationality Some Recent Game-Theoretic Results. Identification and Estimation of Local Average Treatment Effects

This paper undertakes an assessment of a rapidly growing body of economic research on financial literacy. We start with an overview of theoretical research which casts financial knowledge as a form of investment in human capital. Endogenizing financial knowledge has important implications for welfare as well as policies intended to enhance levels of financial knowledge in the larger population. Next, we draw on recent surveys to establish how much (or how little) people know and identify the least financially savvy population subgroups. This is followed by an examination of the impact of financial literacy on economic decision-making in the United States and elsewhere. While the literature is still young, conclusions may be drawn about the effects and consequences of financial illiteracy and what works to remedy these gaps. A final section offers thoughts on what remains to be learned if researchers are to better inform theoretical and empirical models as well as public policy.

The Economic Importance of Financial Literacy: Theory and Evidence


 We administered the FINRA Foundation's National Financial Capability Study questionnaire to members of the RAND American Life Panel in 2012 and 2018. Using this unique, longitudinal data set, we investigate the evolution of financial literacy over time and shed light on the effect of financial knowledge on financial outcomes. Over a six-year observation period, financial literacy appears to be rather stable, with a slight tendency to decline at older ages. Importantly, financial literacy has significant predictive power for future financial outcomes, even after controlling for baseline outcomes and a wide set of demographics and individual characteristics that influence financial decision making.

The evolution of financial literacy over time and its predictive power for financial outcomes: evidence from longitudinal data

The shift to defined contribution pensions requires people to be knowledgeable about finance and economics, yet evidence suggests that even basic numeracy is poor amongst a sizeable proportion of working adults. This chapter discussed the evidence and the provision of financial education programmes that are designed to address the problem. It then goes on to consider ways of improving financial education and alternative ways of stimulating retirement planning.

Financial Literacy and the Shift From Defined Benefit to Defined Contribution Pension Plans

This paper examines Americans' financial capability, using data from a new survey. Financial capability is measured in terms of how well people make ends meet, plan ahead, choose and manage financial products, and possess the skills and knowledge to make financial decisions. The findings reported in this work paint a troubling picture of the state of financial capability in the United States. The majority of Americans do not plan for predictable events such as retirement or children's college education. Most importantly, people do not make provisions for unexpected events and emergencies, leaving themselves and the economy exposed to shocks. To understand financial capability, it is important to look not only at assets but also at debt and debt management, as an increasingly large portion of the population carry debt. In managing debt, Americans engage in behaviors that can generate large expenses, such as sizable interest payments and fees. Moreover, more than one in five Americans has used alternative (and often costly) borrowing methods (payday loans, advances on tax refunds, pawn shops, etc.) in the past five years. The most worrisome finding is that many people do not seem well informed and knowledgeable about their terms of borrowing; a sizeable group does not know the terms of their mortgages or the interest rates they pay on their loans. Finally, the majority of Americans lack basic numeracy and knowledge of fundamental economic principles such as the workings of inflation, risk diversification, and the relationship between asset prices and interest rates.

Resilience and wellbeing in the midst of the COVID-19 pandemic: The role of financial literacy

The objective of this paper is to determine Americans’ mobility patterns into and out of poverty in their later years. We track how older adults enter into and exit from poverty using the most extensive longitudinal survey on older Americans currently available, the Health and Retirement Study (HRS). Using over 20 years of data from the HRS, we show that the conditional probability of escaping poverty diminishes as the number of years in poverty rise. In particular, older adults’ chances of exiting poverty fall sharply as their time in poverty lengthens, especially between four and eight years. Having been in poverty that long, the chances of exiting poverty then levels out. These results imply that poverty among the US elderly can be quite a persistent state for many older adults although individuals that escape poverty are often able to have income above the poverty line in future years.
