Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of choice preferences or norms, or rather the absence of sufficient resources for immediate needs. It is also not clear whether these reflect true differences in choice patterns between income groups. We tested temporal discounting and five intertemporal choice anomalies using local currencies and value standards in 61 countries (N = 13,629). Across a diverse sample, we found consistent, robust rates of choice anomalies. Lower-income groups were not significantly different, but economic inequality and broader financial circumstances were clearly correlated with population choice patterns.

With the increasing popularity of new media, problems involving its excessive use have emerged. The main aim of the study was to analyze the associations between Facebook intrusion, Internet addiction, self-esteem, and life satisfaction in Italy and the USA. We administered the Facebook Intrusion Scale, Internet Addiction Test, Self-Esteem Scale, and Satisfaction with Life Scale. The participants in the online study were N = 555 Italian and American Facebook users, aged 18 to 59 in the case of Italy (M = 24.66, SD = 6.52) and 17 to 67 in the case of the USA (M = 23.65, SD = 10.96). The results showed that the relations between the Internet and Facebook use and life satisfaction are not universal. The study revealed that in Italy, Facebook intrusion was associated with higher life satisfaction, and in the USA, Internet addiction was associated with lower life satisfaction. In both countries, Internet addiction was associated with higher Facebook intrusion and lower self-esteem.

The increase in the number of users of social networking sites (SNS) has inspired intense efforts to determine intercultural differences between them. The main aim of the study was to investigate the cultural and personal predictors of Facebook intrusion. A total of 2628 Facebook users from eight countries took part in the study. The Facebook Intrusion Questionnaire, the Ten-Item Personality Inventory, and the Singelis Scale were used. We found that two variables related to Country were significantly related to Facebook intrusion: uniqueness (negatively) and low context (positively); of the personality variables, conscientiousness, and emotional stability were negatively related to the dependent variable of Facebook intrusion across different countries, which may indicate the universal pattern of Facebook intrusion. The results of the study will contribute to the international debate on the phenomenon of SNS.

Increasing problems connected with excessive Internet use can be observed all over the world. Internet addiction is defined as excessive involvement in the Internet with negative consequences. The main aim of the study was to investigate economic indicators as correlates of Internet addiction. The study was conducted in nine countries. The number of participants amounted to a total of 3,279 Internet users (54% were female), with a mean age of M = 25.14(SD = 10.03). The authors used Young's Internet Addiction Test. Additionally, some social and economic indicators characterizing the countries were taken into consideration. We found that Internet addiction was positively related to economic well-being, social progress, and human development as well as negatively related to human well-being, health, safety, and security. The results of the study contribute to the international debate on Internet addiction.
