    Abstract: Behavioral economics is an innovative applied science. In the 1950s economic rational choice models came under scrutiny. A theoretical critique emerged that not all human beings strive for efficiency and rationality all the time. Behavioral economics first drew attention to deviations from rationality and discussed the non-applicability of rational choice models for depicting the actual behavior of humans. During the 1970s, Amartya Sen formalized the rational choice critique and published powerful examples of how economics needs a reality check and backtesting of its core axioms of rationality, efficiency and time consistency for actual real-world relevancy and external validity of the standard rational choice claims. By 1979, the two psychologists Daniel Kahneman and Amos Tversky presented a line of laboratory experiments at universities that proved the rational choice theory to be inaccurate to explain the real-world decision-making patterns of individuals. The following behavioral economics revolution rewrote economics for accuracy and predictability for actual human day-to-day choices and behavior. Sociologists, political scientists, psychologists created a line of research to describe how individuals actually decide during the first decade of the 2000s. Behavioral insights were then used to find ways how to ‘nudge’ individuals, communities and leaders to help others make better choices in different domains, for instance such as finance, marketing, health and well-being. Around the world, governmental officials and governance experts adopted behavioral nudges and winks to create better choice architectures and decision-making patterns. This paper describes the history of behavioral economics with attention to North American roots and European interpretations in order to then prospect future trends in behavioral economics. First, given the enormous popularity behavioral economics has enjoyed in the most recent decades, a general knowledge has formed about behavioral nudges. Libertarian paternalism is – by now – limited when it comes to implicitly tricking people into making choices based on well-known insights. A common body of knowledge on behavioral aspects of choice patterns may lead to reactance if people notice manipulation. The general population should therefore be trained to make self-empowered choices that meet their individual principles, needs and wants based on their behavioral expertise. Behavioral economists should move from manipulating nudges to educating trainings of the layperson. Second, the field of behavioral sciences has experienced a deep replication crisis given major data cheating scandals and contemporary fraud allegations. General oversight mechanism between co-authors, backtesting of effects for validity and their general applicability is therefore warranted. he general population should be trained to be critical of behavioral insights presented to them and be encouraged by behavioral economists to feedback on the potential non-applicability of p-hacked results. Third, online searchplace distortion of behavioral economics results has become a sad reality for young behavioral economists in the strategic search engine results manipulation through Search Engine Disoptimization (SEDO). This implicit internet harassment calls for a democratization of information and whole-rounded inclusion of thoughts online. Behavioral economists should raise awareness for this negative competitive behavior and work together with global governance institutions, regulatory bodies but also industry professionals to curb negative internet search engine manipulation and empower the upcoming generation of behavioral economists to speak up when this is happening. Professional bodies should be informed to help those whose career has been hit by competitive internet manipulation. All these trends are speculated to lead to a revamped behavioral economics revolution that demands for behavioral economics for all. The future of behavioral economics is believed to lie in self-empowered leadership, not manipulation. A democratization of behavioral economics information leading to a general knowledge basis on actual behavioral patterns will guide a self-empowered decision-making cadre within the general population. Search for true and credible behavioral insights can lift the entire field to a more helpful stage to become a standing guidepost for wise quality decision-making. The digital millennium calling for fair internet use will hopefully prosper an inclusive and diversified information on behavioral insights to be accessible, useful and meaningful for all.

    Abstract: I develop a theoretical framework to study gains from trade and optimal tariffs in the presence of behavioral biases. I introduce a sufficient statistic, called “behavioral wedge, †that generalizes the model to capture various types of behavioral biases, including utility misperceptions and inattention. First, I explore how behavioral biases influence gains from trade, demonstrating potential welfare losses from trade for behavioral agents. Second, I characterize optimal tariffs and behavioral nudges in the presence of behavioral biases. I show that small open economies can leverage trade policy to mitigate the welfare losses from behavioral biases, whereas larger economies might use nudges to manipulate the world’s terms of trade. Finally, I discuss the role of behavioral biases in shaping public support for the 2018 China–United States trade war and Brexit.

    Abstract: Cognitive dissonance may arise from the inconsistency between an individual's behavior and her self-image. We investigate whether the provision of information that induces cognitive dissonance can increase sustainable consumption, and specifically whether individuals avoid cognitive dissonance by (a) a change in behavior to comply with own attitudes and by (b) two types of self-deception: the denial of attitudes and the denial of knowledge about the criticism of conventional online shopping. To this end, we develop a rational choice model and embed an incentivized discrete-choice task in a large-scale survey conducted in Germany in 2021, with the choice being between a voucher for either a conventional or a sustainable online market place. In an experimental setting, we aim to induce cognitive dissonance by either randomly reminding participants of their previously stated attitudes towards sustainable production or by informing them about the typical criticism of conventional online shopping. Results indicate that individuals adapt their behavior after having received the reminder of their stated attitudes and the criticism about conventional online shopping. Yet, participants do not deceive themselves by aligning their attitudes with their behavior or by denying to have been aware of the criticism.
    Abstract: Kognitive Dissonanz kann aus der Inkonsistenz zwischen dem Verhalten einer Person und ihrem Selbstbild entstehen. Wir untersuchen, ob die Bereitstellung von Informationen, die kognitive Dissonanz hervorrufen, den nachhaltigen Konsum steigern kann, und insbesondere, ob Individuen kognitive Dissonanz vermeiden, indem sie (a) ihr Verhalten ändern, um den eigenen Einstellungen zu entsprechen, und (b) zwei Arten von Selbsttäuschung betreiben: die Verleugnung von Einstellungen und die Verleugnung von Wissen über die Kritik am konventionellen Online-Shopping. Zu diesem Zweck entwickeln wir ein Rational-Choice-Modell und betten eine incentivierte Discrete-Choice-Aufgabe in eine groß angelegte Umfrage ein, die 2021 in Deutschland durchgeführt wird, wobei die Wahl zwischen einem Gutschein für einen konventionellen oder einen nachhaltigen Online-Marktplatz besteht. In einem experimentellen Setting zielen wir darauf ab, kognitive Dissonanz zu induzieren, indem wir die Teilnehmenden entweder zufällig an ihre zuvor geäußerte Einstellung zu nachhaltiger Produktion erinnern oder sie über die typische Kritik am konventionellen Online-Einkauf informieren. Die Ergebnisse zeigen, dass die Teilnehmenden ihr Verhalten anpassen, nachdem sie an ihre Einstellungen erinnert und über die Kritik am konventionellen Online-Shopping informiert wurden. Sie täuschen sich jedoch nicht selbst, indem sie ihre Einstellungen mit ihrem Verhalten in Einklang bringen oder leugnen, von der Kritik gewusst zu haben.
