Law and Economics in All His Facets: Festschrift in Honour of Klaus Mathis

Only a small portion of the substantial literature on behavioral interventions ("nudges") that developed over the last fifteen to twenty years has considered nudges from an economic perspective. Moreover, despite the importance of the topic for a law and economics assessment of this increasingly common form of regulation, even fewer contributions have examined whether and when behavioral instruments are likely to make an efficient means for increasing social welfare. This chapter therefore offers some basic observations about nudge efficiency: Part I opens with a reminder that behavioral …

Digital nudges—that is, significantly behavioral interventions that use software and its user-interface design elements—are an increasingly pervasive feature of online environments that shapes behavior both online (e.g., changing online privacy settings) and offline (e.g., taking a flu vaccine due to a text message reminder).

The Law And Economics Of Behavioral Regulation, Avishalom Tor

Journal Articles

This article examines the law and economics of behavioral regulation (“nudging”), which governments and organizations increasingly use to substitute for and complement traditional instruments. To advance its welfare-based assessment, Section 1 examines alternative nudging definitions and Section 2 considers competing nudges taxonomies. Section 3 describes the benefits of nudges and their regulatory appeal, while Section 4 considers their myriad costs—most notably the private costs they generate for their targets and other market participants. Section 5 then illustrates the assessment of public and private welfare nudges using cost-benefit analysis, cost-effectiveness analysis, and rationality-effects analysis.
