COVID-19 policies in Germany and their social, political, and psychological consequences

Abstract: Many policy analyses on COVID-19 have been focusing on what kind of policies are implemented to contain the spread of COVID-19 What seems equally important to explore are the social and political consequences of the confinement policies Does the public support strict confinement policies? What are the social, political, and psychological consequences of the confinement policies? The question of how legitimate a policy is among the public is at the core of democratic theory Its relevance also stems from the expected consequences of public support on behavior: The more someone supports a policy, the more someone is likely to follow the policy even if the policy is not strictly enforced In this paper, we will focus on Germany, briefly summarize the main policies during the first 6 weeks of confinement and then explore political attitudes, risk perceptions, and the social consequences of the lockdown

A Bayesian model-averaged meta-analysis of the power pose effect with informed and default priors: the case of felt power

Abstract: Earlier work found that – compared to participants who adopted constrictive body postures – participants who adopted expansive body postures reported feeling more powerful, showed an increase in testosterone and a decrease in cortisol, and displayed an increased tolerance for risk. However, these power pose effects have recently come under considerable scrutiny. Here, we present a Bayesian meta-analysis of six preregistered studies from this special issue, focusing on the effect of power posing on felt power. Our analysis improves on standard classical meta-analyses in several ways. First and foremost, we considered only preregistered studies, eliminating concerns about publication bias. Second, the Bayesian approach enables us to quantify evidence for both the alternative and the null hypothesis. Third, we use Bayesian model-averaging to account for the uncertainty with respect to the choice for a fixed-effect model or a random-effect model. Fourth, based on a literature review, we obtained an em...

Exploring influencing factors on rationality: A literature review of dynamic decision making studies in system dynamics

Abstract: Simulators and experiments studying dynamic decision making offer a way of finding out about factors enforcing and inhibiting human rationality. This literature review of 51 studies from the system dynamics field helps to identify various factors that influence decision making. The factors are classified into model, simulator and player characteristics. In the paper the effect of these variables on gaming performance is reviewed and synthesized. Model characteristics such as presence of delay and increase of feedback strength seem to lower performance, while changes in exogenous conditions lead to mixed results. With regard to simulator characteristics, the decision interval does not seem to influence performance. Model transparency has a positive relation to performance, similar to decision information (in conjunction with player characteristics). Lastly, with regard to player characteristics, there is some evidence that a long-term goal increases performance. Although problem-solving style and mental model characteristics impact performance, no relation between general personality types and performance is found. Also, there are no consistent differences between individuals and pairs with regard to performance. The paper closes with brief comments on future research directions.

Do transfer pricing laws limit international income shifting? Evidence from European multinationals.

Abstract: In recent years several countries have augmented their national tax laws bytransfer pricing legislations which intend to limit the leeway of multinational firms to exploit international corporate tax rate diverences and relocate profit to low-tax affiliates by distorting intra-firm transfer prices. The aim of this paper is to empirically investigate whether these laws are instrumental in restricting shifting behaviour. To do so, we exploit unique information on the scope and evolution of national transfer pricing laws and link it with panel data on European multinationals. In line with previous studies, we find evidence for tax-motivated profit shifting. The analysis further suggests that transfer pricing rules significantly reduce shifting activities. The effect is economically relevant, suggesting that the legislations may be socially desirable despite the high administrative burden they impose on firms and tax authorities.
