    Abstract: Beyond a summary of the paper, this review of "Group Identity and Social Preferences" by Yan Chen and Sherry X. Li highlights its exceptional impact on our understanding of group-contingent social preferences. This paper has made an important theoretical contribution by introducing group identity in the Charness and Rabin (2002)'s model of social preferences. The core of the contribution is to show experimentally that social identity influences distributional preferences, reciprocity and welfare-maximizing behavior. In particular, charity increases and envy decreases when people are matched with an in-group compared to an out-group, and people are more likely to reward and less likely to punish an ingroup than an out-group match. This paper has also contributed to the methodological debates about the use of minimal group identity in laboratory experiments. It has inspired many research programs on the role of group-contingent preferences in various dimensions of decision-making in society. It is also important to emphasize its policy implications regarding how groupcontingent social preferences could be activated to improve efficiency and the quality of social interactions in our segmented societies. This research agenda is more relevant than ever.

    Abstract: This paper investigates the effect of child dependency on the economy and external imbalances under an asymmetric demographic and productivity transition within a lifecycle model. It embeds dependent children within a two-country model with lifecycle features to examine child dependency’s effect on the economy and external imbalances. Specifically, the paper compares the effects of the same fertility and mortality shocks across models with and without children. Simulations show that child dependency changes both the steady-state and the transition dynamics under a demographic shock. The paper finds that while child dependency changes the direction of the impact of the fertility transition on external imbalances in the short run, it changes the magnitude of the effects in the long run. Furthermore, the model comparison shows that parameters must be chosen differently across models with and without child dependency to start from the same interest rate in the steady-state. Different calibration affects the magnitude of the transition dynamics of different models. These findings illustrate the importance of considering child dependency in studies that seek to explain the historical contribution of demographic changes to external imbalances, and suggest to approach studies that use models without child dependency for this purpose with caution.

    Abstract: Several physical features influence the perception of how cooperative a potential partner is. While previous work focused on face and voice, it remains unknown whether body odours influence judgements of cooperativeness and if odour-based judgements are accurate. Here, we first collected axillary odours of cooperative and uncooperative male donors through a public good game and used them as olfactory stimuli in a series of tasks examining whether and how they influence cooperative decision-making in an incentivized economic game and ratings of cooperativeness. Our results show that having access to the donor's body odours provided a strategic advantage to women during economic decisions (but not to men): with age, women were more likely to cooperate with cooperative men and to avoid interacting with uncooperative men. Ratings of cooperativeness were nonetheless unrelated to the donors' actual cooperativeness. Finally, while men with masculine and intense body odours were judged less cooperative, we found no evidence that donors' actual cooperativeness was associated with less masculine or less intense body odour. Overall, our findings suggest that, as faces and voices, body odours influence perceived cooperativeness and might be used accurately and in a non-aware manner as olfactory cues of cooperativeness, at least by women..

    Abstract: A large body of research in economics and other disciplines considers the role of early-life circumstances in shaping later-life outcomes. The foetal origins hypothesis establishes that certain health conditions in later adulthood can be linked to in-utero development. In this paper, we contribute to the evidence on the foetal origins hypothesis by examining the later-life impact of a rubella outbreak that occurred in Ireland in 1956. Rubella is a contagious viral disease that displays mild symptoms and is generally inconsequential in childhood or adulthood. However, a rubella infection in early pregnancy poses a significant risk of damage to the foetus. Matching the outcomes of individuals born in 1955 to 1958 who are in the 2016 Irish Census to the county-level rubella incidence rate that was prevailing when respondents were in utero, we find that a 1% increase in the rubella incidence rate when in utero is associated with a 0.03% to 0.17% increase in the probability of having lower levels of educational attainment, being in poor health and having a disability in later life.

    Abstract: For decades, the debate on using DDT to control malaria has focused on the balance between immediate public health gains and ecological costs, ignoring DDT's long-term harmful effects on humans. Using data from the large-scale indoor residual spraying of DDT that took place in Taiwan in the 1950s, we estimate the long-term effects of DDT exposure in early childhood on education and employment in adulthood. Our identification hinges on the unexpected extension of DDT spraying even after malaria had already been largely brought under control. Our finding shows that DDT exposure in early childhood is associated with less education and worse employment in adulthood. However, the dose-response curves are non-linear.
