Notes on Behavioral Economics and Labor Market Policy
Notes on Behavioral Economics and Labor Market Policy Linda Babcock, Carnegie Mellon University William J. Congdon, The Brookings Institution Lawrence F. Katz, Harvard University Sendhil Mullainathan, Harvard University December 2010 We are grateful to Jeffrey Kling for extensive discussions of these topics. We thank the Alfred P. Sloan Foundation and the Russell Sage Foundation for their support of this project. 0. Background and motivation Recent years have been trying ones for American workers. The unemployment rate has reached double digits for the first time in over a quarter of a century. Worker compensation growth has all but stalled. The human costs of labor market turbulence have rarely been clearer, and the value of public policies, such as unemployment insurance and job training programs, that assist workers in managing that turbulence, gaining new skills, and navigating the labor market have rarely been more apparent. And, even in the best of times, the United States’ labor market is a dynamic and turbulent one, with high rates of turnover (over five million separations and five million new hires in a typical month in normal times) but substantial frictions as well. As a result, labor market programs and regulations are key components of economic policy. Such policies help support the unemployed, provide education and training opportunities, and ensure the fairness, safety, and accessibility of the workplace. The challenge for policymakers is to design such policies so that they meet these goals as effectively and as efficiently as possible. Labor market policies succeed in meeting their objectives, however, only to the extent that they accurately account for how individuals make decisions about work and leisure, searching for jobs, and taking up opportunities for education and training. -

Decision Making and Keynesian Uncertainty in Financial Markets: an Interdisciplinary Approach
Decision making and Keynesian uncertainty in financial markets: an interdisciplinary approach Ms Eirini Petratou, PhD candidate in Economics division, Leeds University Business School Abstract: This interdisciplinary research examines decision-making in financial markets, regarding secondary markets and financial innovation in Europe, so as to unveil the multiple dimensions of this complexly-layered world of financial interactions. Initially, I synthesise different literatures, including Post-Keynesian economics, behavioural economics and finance, and decision-making theory, in order to shape a more complete understanding of behaviours and outcomes in financial markets. Particularly, I focus on an analysis of Keynesian uncertainty in order to show the need of economic science for interdisciplinary research, on theoretical and methodological levels, and also to highlight potential links between Post-Keynesian theory and behavioural economics. After presenting the active role of decision-making under uncertainty into the creation of financial bubbles, as incorporated in Post-Keynesian economics, I support my argument by presenting findings obtained by a series of semi-structured interviews I conducted in 2016 in the UK, in order to investigate financial traders’ beliefs, perspectives and terminology about decision-making under uncertainty in financial markets. The goal of this qualitative project is to identify market professionals’ beliefs about market uncertainty and how they deal with it, to find out their knowledge about causes of the -
Volatility As Link Between Risk and Memory in Economics, Econometrics and Neuroeconomics: an Application for the Bolivian Inflation Rate 1938 - 2012
Volatility as link between risk and memory in Economics, Econometrics and Neuroeconomics: an application for the Bolivian Inflation Rate 1938 - 2012 María Edith Chacón B. [email protected] Teacher and researcher CIDES – UMSA. La Paz, Bolivia. Ernesto Sheriff B. [email protected] Teacher and researcher CIDES – UMSA and UPB. La Paz, Bolivia. Experimental and Behavioral Economics: Other Neuroeconomics Econometrics: Time Series ABSTRACT This paper provides an indicator that measures memory as a stock. Memory affects economic decisions thus the memory indicator is useful to help in applied work, it was built according to the state of the art in Psychology and Neuroeconomics and it is presented as a time series; it is a recursive one and it is represented by an accumulated measure of the volatility. Many theories of risk have used volatility indicators to represent risk in the applied work. Risk valuation is associated to volatility and it is very sensitive to periods in which it is measured; it is very sensitive too to the type of data associated to volatility. In this paper we found that the memory affects risk valuations and the link between them is a special kind of volatility i.e. accumulated volatility with an endogenous initialization period and compatible with many Psychological hypotheses. The developed indicator is compatible with the econometrics of stationary series, integrated series and fractional integrated series. These contributions help to improve the study of hysteresis in applied economics, to develop more consistent links between memory and risk in Neuroeconomics and, to obtain more confident time series models in econometrics using the new indicator. -

The Future of Economics in a Lakatos–Bourdieu Framework
Munich Personal RePEc Archive The Future of Economics in a Lakatos–Bourdieu Framework. Heise, Arne University of Hamburg 2014 Online at https://mpra.ub.uni-muenchen.de/80024/ MPRA Paper No. 80024, posted 05 Jul 2017 05:42 UTC The Future of Economics in a Lakatos-Bourdieu framework Prof. Arne Heise University of Hamburg Dep. of Socioeconomics VMP 9 D-20146 Hamburg [email protected] Abstract The global financial crisis has clearly been a matter of great consternation for the busi- ness-as-usual faction of mainstream economics. Will the World Financial Crisis turn out to be that ‘experimentum crucis’ which triggered a scientific revolution? In this paper, we seek to assess the likelihood of a paradigm shift towards heterodox approaches and a more pluralist setting in economics emerging from the academic establishment in the U.S. – that is, from the dominant center of knowledge production in the economic disci- pline. This will be done by building the analysis on a combined Lakatosian framework of ‘battle of research programmes’ and a Bourdieuian framework of ‘power struggle’ within the academic field and highlighting the likelihood of two main proponents of the mainstream elite to become the promulgator of change?

The Keynesian Revolution and Pragmatic Pluralism – A Fruitful Competition Between Theories or a Crisis in Economics? John Maynard Keynes concludes ‘The General Theory of Employment, Interest, and Money’ (1936: 383-84) with the following, now-famous words: „At the present moment people are unusually expectant of a more funda- mental diagnosis; more particularly ready to receive it; eager to try it out, if it should be even possible. -
Neuroeconomics and the Study of Addiction
Neuroeconomics and the Study of Addiction John Monterosso, Payam Piray, and Shan Luo We review the key findings in the application of neuroeconomics to the study of addiction. Although there are not “bright line” boundaries between neuroeconomics and other areas of behavioral science, neuroeconomics coheres around the topic of the neural representations of “Value” (synonymous with the “decision utility” of behavioral economics). Neuroeconomics parameterizes distinct features of Valuation, going beyond the general construct of “reward sensitivity” widely used in addiction research. We argue that its modeling refinements might facilitate the identification of neural substrates that contribute to addiction. We highlight two areas of neuroeconomics that have been particularly productive. The first is research on neural correlates of delay discounting (reduced Valuation of rewards as a function of their delay). The second is work that models how Value is learned as a function of “prediction-error” signaling. Although both areas are part of the neuroeconomic program, delay discounting research grows directly out of behavioral economics, whereas prediction-error work is grounded in models of learning. We also consider efforts to apply neuroeconomics to the study of self-control and discuss challenges for this area. We argue that neuroeconomic work has the potential to generate breakthrough research in addiction science. Key Words: Addiction, behavioral economics, delay discounting, limbic targets, especially the ventral striatum (3). One hypothesis is neuroeconomics, prediction error, substance dependence that individuals with relatively weak responses to reward “tend to be less satisfied with natural rewards and tend to abuse drugs and he behavior of someone with an addiction can be frustrating alcohol as a way to seek enhanced stimulation of the reward path- and perplexing. -

Uncertainty, Evolution, and Behavioral Economic Theory
UNCERTAINTY, EVOLUTION, AND BEHAVIORAL ECONOMIC THEORY Geoffrey A. Manne, International Center for Law & Economics Todd J. Zywicki, George Mason University School of Law Journal of Law, Economics & Policy, Forthcoming 2014 George Mason University Law and Economics Research Paper Series 14-04 Uncertainty, Evolution, and Behavioral Economic Theory Geoffrey A. Manne Executive Director, International Center for Law & Economics Todd J. Zywicki George Mason University Foundation Professor of Law George Mason University School of Law Abstract: Armen Alchian was one of the great economists of the twentieth century, and his 1950 paper, Uncertainty, Evolution, and Economic Theory, one of the most important contributions to the economic literature. Anticipating modern behavioral economics, Alchian explains that firms most decidedly do not – cannot – actually operate as rational profit maximizers. Nevertheless, economists can make useful predictions even in a world of uncertainty and incomplete information because market environments “adopt” those firms that best fit their environments, permitting them to be modeled as if they behave rationally. This insight has important and under-appreciated implications for the debate today over the usefulness of behavioral economics. Alchian’s explanation of the role of market forces in shaping outcomes poses a serious challenge to behavioralists’ claims. While Alchian’s (and our) conclusions are born out of the same realization that uncertainty pervades economic decision making that preoccupies the behavioralists, his work suggests a very different conclusion: The evolutionary pressures identified by Alchian may have led to seemingly inefficient firms and other institutions that, in actuality, constrain the effects of bias by market participants. In other words, the very “defects” of profitable firms — from conservatism to excessive bureaucracy to agency costs — may actually support their relative efficiency and effectiveness, even if they appear problematic, costly or inefficient. -
Title the Possibility of Behavioral New Institutional Economics Sub Title Author 菊沢, 研宗
Title The possibility of behavioral new institutional economics Sub Title Author 菊沢, 研宗(Kikuzawa, Kenshu) Publisher Society of Business and Commerce, Keio University Publication year 2011 Jtitle Keio business review No.46(2011) ,p.25(1)- 42(18) Abstract Behavioral economics has recently been the subject of considerable research with the consequence that theories in behavioral economics and finance have complementarily developed to comprise a research field known as 'behavioral finance'. Subsequent studies seeking to integrate game theory and behavioral economics come under the 'behavioral game theory' umbrella, while those wanting to integrate contract theory and behavioral economics fall under 'behavioral contract theory'. Given such circumstances, the remaining avenue to explore is the integration of behavioral economics and new institutional economics, the latter consisting of transaction cost economics, agency theory, and the theory of property rights. This paper pursues this remaining possibility and indeed proves that 'behavioral new institutional economics' can be developed and would be a fruitful new field of research.
