Few studies have examined birth order effects on personality in countries that are not Western, educated, industrialized, rich, and democratic (WEIRD). However, theories have generally suggested that interculturally universal family dynamics are the mechanism behind birth order effects, and prominent theories such as resource dilution would predict even stronger linear effects in poorer countries. Here, we examine a subset of up to 11 188 participants in the Indonesian Family Life Survey to investigate whether later–borns differ from earlier–borns in intelligence, educational attainment, Big Five, and risk aversion. Analyses were performed using within–family designs in mixed–effects models. In model comparisons, we tested for linear and non–linear birth order effects as well as for possible interactions of birth order and sibship size. Our estimated effect sizes are consistent with the emerging account of birth order as having relatively little impact on intelligence, Big Five, and risk aversion. We found a non–linear pattern for educational attainment that was not robust to imputation of missing data and not aligned with trends in WEIRD countries. Overall, the small birth order effects reported in other studies appear to be culturally specific. © 2020 The Authors.

Unique Dataset

The literature on risk aversion suggests that women are less likely to be risk loving than men in financial and insurance decision-making by virtue of their sex and biological make-up. This paper tests this assertion using a unique dataset collected in Ghana and Uganda and assesses the gender differences in self-reported risk perceptions of entrepreneurs by applying a non-linear decomposition technique. The results indicate that on average, entrepreneurs in Ghana report to be less risk loving their counterparts in Uganda. Furthermore, female entrepreneurs are less likely to report to be risk loving compared to male entrepreneurs in both countries. The results from the decomposition analysis show that gender differences in risk perceptions arise mainly from the unexplained component. For Ghana in particular, the findings show that the gender differences in self-reported risk perceptions stems from differences in education and previous business experience.

Preceding Session

(Ed. note: The custom in these Symposia has been to have a summary-introductory presentation which lasts about 1 to 1.5 hours, during which discussion from the floor is minor and usually directed at technical clarification. The remainder of the session is then devoted to discussion of the whole subject, oriented around the summary-introduction. The preceding session, I-A, at Nice, followed this pattern. Christy suggested that we might experiment in his presentation with a much more informal approach, allowing considerable discussion of the points raised in the summary-introduction during its presentation, with perhaps the entire morning spent in this way, reserving the afternoon session for discussion only. At Varenna, in the Fourth Symposium, several of the summaryintroductory papers presented from the astronomical viewpoint had been so full of concepts unfamiliar to a number of the aerodynamicists-physicists present, that a major part of the following discussion session had been devoted to simply clarifying concepts and then repeating a considerable amount of what had been summarized. So, always looking for alternatives which help to increase the understanding between the different disciplines by introducing clarification of concept as expeditiously as possible, we tried Christy's suggestion. Thus you will find the pattern of the following different from that in session I-A. I am much indebted to Christy for extensive collaboration in editing the resulting combined presentation and discussion. As always, however, I have taken upon myself the responsibility for the final editing, and so all shortcomings are on my head.)
