When Giulia and Andrea meet Salma and Omar: Essays on cultural adaptation. Theory and Evidence

This dissertation consists of essays that examine the factors that affect the integration patterns in a culturally diverse society. In the first chapter, I introduce a theoretical model consisting of a cultural adaptation game focusing on the effects of strength of group identity and share of the minority in the population on the adaptation levels. The model focuses on the trade-off between coordinating with own group members by playing a pure coordination game and cooperating with other group members by playing a variant of a public good game. The model predicts that with low proportions of minority, only minority adapts and majority does not, however as the share of a minority increases, the likelihood of no one adapting increases even though mutual adaptation is Pareto dominant and socially optimal. In Chapter 2, I test the predictions of the model and the possible ways to improve efficiency in a laboratory experiment. The experiment follows the structure of the cultural adaptation game where mutual adaptation is socially optimal. The results from the experiment are in line with the theoretical results where, with a one-third share of minority, the likelihood of no one adapting increases. Therefore, to improve efficiency, I introduce the possibility of communication through a leader. The results show that only involving leaders with high ability and who can send a message to all the participants irrespective of the group can lead to mutual adaptation. The last chapter is a literature review on the role of the host country characteristics affecting the adaptation patterns of immigrants combining literature from economics, political science and cross-cultural psychology. This dissertation contributes thematically and methodologically to the existing literature by enhancing our understanding of the cultural adaptation process and how we can improve efficiency in today’s globalized world where inter-cultural contact is inevitable

Behavioral correlates of mask wearing among COVID-19 frontline workers

Human behavior can have effects on oneself and externalities on others. Mask wearing is such a behavior in the current pandemic. What motivates people to wear face masks in public when mask wearing is voluntary or not enforced? Which benefits should the policy makers rather emphasize in information campaigns|the reduced chances of getting the SARS-CoV-2 virus (benefits for oneself) or the reduced chances of transmitting the virus (benefits for others in the society)? In this paper, we link measured risk preferences and other-regarding preferences to mask wearing habits among 840 surveyed employees of two large Swiss hospitals. We find that the leading mask-wearing motivations change with age: While for older people, mask wearing habits are best explained by their self-regarding risk preferences, younger people are also motivated by other-regarding concerns. Our results are robust to different specifications including linear probability models, probit models and Lasso covariate selection models. Our findings thus allow drawing policy implications for effectively communicating public-health recommendations to frontline workers during the COVID-19 pandemic

Which hospital workers do (not) want the jab? Behavioral correlates of COVID-19 vaccine willingness among employees of Swiss hospitals

In many countries, the current vaccination rates are stagnating, to the extent that vaccine hesitancy { the delay or refusal to take recommended vaccinations { forms a major obstacle to ending the COVID-19 pandemic. This tendency is particularly concerning when observed among healthcare workers who are opinion leaders on medical matters for their patients and peers. Our study surveys 965 employees of two large Swiss hospitals and profiles vaccine-hesitant hospital employees using not only socio-demographic characteristics, but also a comprehensive set of standard behavioral preference measures: (i) Big-5 personality traits, (ii) risk-, time- and social preferences, and (iii) perceived prevailing social norms. Using multinomial probit models and linear probability models, we find that vaccine-hesitant hospital employees are less patient and less likely to perceive vaccination as the prevailing social norm { in addition to replicating previously published socio-demographic results. Our findings are robust to a range of model specifications, as well as individual and situational covariates. Our study thus offers actionable policy implications for tailoring public-health communications to vaccine-hesitant hospital employees
