Who is afraid of nudges?


Roughly ten years have passed since the publication of Thaler and Sunstein’s seminal article “Libertarian Paternalism” (American Economic Review 2006) and their book Nudge—Improving Decision about Health, Wealth and Happiness (Penguin 2008).  Their work has generated critical academic reviews, policy papers and actual policy initiatives.  We will take stock of some of the recurring themes in this literature.  What sets Nudges apart among other behavioural public policies?  Does a government respect the autonomy and dignity of its citizens when instituting Nudge policies?  Does it respect the transparency that we expect from public policies?  Are randomised controlled trials a fitting methodology to evaluate candidate policies?  And finally, what can be learned from comparing the choice architectures of societies with better and worse outcomes?

Dan Ariely, Duke University
The honest truth about dishonesty


In this talk Dan will discuss how the principles of behavioral economics can help us understand some of our irrational tendencies, specifically the mechanisms at work behind dishonest behavior. One of the most interesting lessons at work is understanding our capacity to think of ourselves as honest even when we act dishonestly. The implications of this research are far reaching and include a better understanding of financial crises, regulations, and day-to-day misbehaviors. These insights are critical for nudging people to display more honest behavior.

Parallel Session 4  |  10.30 – 12.00 hrs

4A. Workshop: Of Nudge, Tools and Bolts

Chair: Peter John, University College London

This panel investigates the newest insights in how behaviorally informed policies become integrated in public policy making. The 3-hr workshop seeks to understand how the relatively simple idea of creating effective nudges plays out in real settings. Which policy interventions, based on behavioral insights, have proven to be effective? How are behavioral insights integrated in policy making? Which areas of application are fruitful? In this workshop, these questions will be addressed by discussing research papers from participants.

4D. Roundtable: To nudge or not to nudge; is nudging in fisheries management necessarily libertarian paternalism?

Chairs: Sarah B. M. Kraak, Thuenen Institute of Baltic Sea Fisheries, Germany & Dorothy J. Dankel, Nordic Marine Think Tank & University of Bergen, Norway

Not complying with fisheries’ regulations is a problem inhibiting the sustainable use of marine ecosystems. Control and enforcement are costly and are not sufficiently effective. Moreover, top-down control and lack of trust undermine intrinsic motivations to comply voluntarily. Can nudging help? Or does it further erode trust?

4E. Workshop: Changing Social Norms: Bicchieri and Sunstein on Mechanisms and Ethics

Chairs: Yashar Saghai, Johns Hopkins University – Marcel Verweij, University of Wageningen and Mariëtte van den Hoven, Utrecht University

Behaviorally informed programs can be led by multiple public actors, the private sector, and civil society. They raise especially hard ethical questions when their ambitious aim is to intervene in the very fabric of social relationships through changing social norms that govern our interactions. The goal of this workshop is to reconstruct and evaluate differences between Cristina Bicchieri’s and Cass Sunstein’s theories of social norms (e.g., expectations-based versus frames-based), the mechanisms through which they can be changed, and the ethical permissibility of changes in social norms initiated by different actors. In this workshop, Yashar Saghai will first discuss these questions through a short presentation of the authors’ positions developed in their recent books (Bicchieri’s Norms in the Wild: How to Diagnose, Measure, and Change Social Norms and Sunstein’s The Ethics of Influence). Second, participants will be divided in three groups guided by workshop facilitators (Marcel Verweij; Mariëtte van den Hoven; Yashar Saghai), with the goal of comparing and evaluating the merits and limits of the explanatory power and of the ethical frameworks underlying each approach through concrete case studies from Bicchieri’s work with UNICEF and Sunstein’s regulatory experiments. Third, at the end of the workshop, participants and facilitators will summarize the findings of the workshop and brainstorm about pathways to move these theoretical debates and practical interventions forward.

4H. Behavioral Insights Network Netherlands

Hosted by Behavioral Insights Network Netherlands (BIN NL). Chairs: Maureen Turina (Ministry of Security and Justice), Hanne Bikker (Ministry of Foreign Affairs), Evelien van de Veer (Ministry of Economic Affairs) and Lisanne Grimberg (Ministry of Education, Culture and Science)

In 2014 Dutch government announced that ministries should make more use of behavioral insights in policy. As a result an interdepartmental network (BIN NL) was founded. This network facilitates the dissemination and application of behavioral insights in policy in several ministries. In this workshop we will present findings on how behavioural insights are integrated in policy making at various ministries.
