“…Bauer and Chytilová (2009) assessed the impact of education on discount rates of Ugandan villagers by exploiting two independent exogenous sources of variation in schooling, across villages and over time, and also found that the degree of delay discounting decreased with education. Similarly, Kirby et al (2002) found that discount rates in Tsimane' Amerindians of the Bolivian rain forest decreased with increases in educational levels and literacy and tended to decrease as recent income rose. Rates were not associated with current wealth.…”

“…But there are also several studies that find no relation between wealth and discount rates (Kirby et al, 2002;Anderson, Dietz, Gordon, & Klawitter, 2004). Since we do not have individual wealth or income information, we use GDP per capita as a proxy for wealth.…”

We present results from the first large-scale international survey on time preference, conducted in 53 countries. All countries exhibit hyperbolic discounting patterns, i.e., the immediate future is discounted more than far future. We also observe higher heterogeneity for shorter time horizons, consistent with the pattern reviewed by Frederick, Loewenstein, and O'Donoghue (2002). Cultural factors as captured by the Hofstede cultural dimensions (Hofstede, 1991) contribute significantly to the variation of time discounting, even after controlling for economic factors, such as GDP, inflation rate and growth rate. In particular, higher levels of Uncertainty Avoidance are associated with stronger hyperbolic discounting, whereas higher degrees of Individualism and Long Term Orientation predict stronger tendency to wait for larger payoffs. We also find the waiting tendency is correlated with innovation, environmental protection, crediting rating, and body mass index at country level after controlling for county wealth. These results help us to enhance the understanding of differences across financial markets and economic behavior worldwide.

“…When faced with such decisions, individuals tend to discount the value of delayed rewards (benefits or costs). The preference for sooner-smaller rewards over later-larger rewards has been referred to as delay discounting (DD) (Frederick et al, 2002;Kirby et al 2002).…”

“…On the one hand, there is evidence suggesting that DD rates may be genetically determined to some extent (Anokhin et al, 2011(Anokhin et al, , 2015Aycinena & Rentschler, 2017;Bevilacqua & Goldman, 2013). On the other hand, people's current socio-economic conditions, as proxied by variables such as education and income, also seem to be related to DD: poorer and less educated individuals have been found to discount the future more heavily (Harrison et al, 2002;Kirby et al 2002;Tanaka et al, 2010), although the causal direction is unclear (Becker & Mulligan, 1997). In addition, a number of behavioral disorders (e.g., attention-deficit/hyperactivity disorder, aggression, suicide, and substance abuse) have been associated with high DD (Barkley et al, 2001;Bickel, & Marsch, 2001;Dombrovski et al, 2011).…”

“…While a number of individual-level studies provide support for the hypothesized relationships (Becker & Mulligan, 1997;Chipman & Morrison, 2015;Green et al, 1996;Griskevicius et al, 2011;Kirby et al 2002;Pender, 1996), few experiments to date have studied to what extent the conditions of harshness and future-unpredictability faced by different groups can predict individual differences in DD. Ramos et al (2013) is, to the best of our knowledge, the only experimental study directly approaching the question.…”

Evolution and Human Behavior

Humans differ greatly in their tendency to discount future events, but the reasons underlying such inter-individual differences remain poorly understood. The evolutionary framework of Life History Theory predicts that the extent to which individuals discount the future should be influenced by socio-ecological factors such as mortality risk, environmental predictability and resource scarcity. However, little empirical work has been conducted to compare the discounting behavior of human groups facing different socio-ecological conditions. In a lab-in-the-field economic experiment, we compared the delay discounting of a sample of Romani people from Southern Spain (Gitanos) with that of their non-Romani neighbors (i.e., the majority Spanish population). The RomaniGitano population constitutes the main ethnic minority in all of Europe today and is characterized by lower socio-economic status (SES), lower life expectancy and poorer health than the majority, along with a historical experience of discrimination and persecution. According to Life History Theory, Gitanos will tend to adopt "faster" life history strategies (e.g., earlier marriage and reproduction) as an adaptation to such ecological conditions and, therefore, should discount the future more heavily than the majority. Our results support this prediction, even after controlling for the individuals' current SES (income and education). Moreover, group-level differences explain a large share of the individual-level differences. Our data suggest that human inter-group discrimination might shape group members' time preferences through its impact on the environmental harshness and unpredictability conditions they face.
