DESCRIPTION:*While 57% of white adults in the U.S. are married\, only 33% o
 f black adults are. Existing research attributes this gap largely to the ma
 le-female ratio\, but this study examines economic prospects as a key facto
 r. By exploiting heterogeneity in discretionary state-level minimum wage hi
 kes\, we identify their impact on marriage rates among low-paid workers of 
 marriageable age. States with wage increases show a 2 percentage point redu
 ction in the racial marriage gap compared to others. Black workers maintain
  or increase work hours\, improving economic prospects while reducing time 
 spent on homeownership\, volunteering\, religious activities\, and acquirin
 g goods and services.**Uncertainty is a part of life and has been widely st
 udied in neuroscience and economics. However\, we still know very little ab
 out how human and other animals cope with very rare (probability below 2%) 
 but extreme (very strong consequences) events (REEs). What happens when we 
 face events that are both rare (you can’t predict its occurrence\, too su
 rprising) and extreme in their consequences (positive\, Jackpot JP - or neg
 ative\, Black Swan BS) ? How do we respond to such events? To explore these
  questions\, our study\, in humans and rats\, employs a four-armed bandit t
 ask with exposure to stochastic gains and losses\, some of which are except
 ionally REEs. Our previous research on rats highlighted their sensitivity t
 o REEs\, with two main strategies:  a total BS avoidance and a partial JP 
 seeking. In this study\, we introduce two tasks for humans\, differing in t
 heir entry method: one through training (implicit learning) and the other t
 hrough a partial description of outcomes (explicit learning). Our findings 
 show that humans have similar strategies in both task and similars to the o
 nes found in rats: they strongly avoid BS and partially seek JP\, with indi
 vidual differences in the strength of these strategies. Interestingly\, the
 re is an asymmetric reactions to REE (gambling fallacy): participants avoid
  BS because they are certain another one will happen (and they fear it)\, w
 hereas when they have a JP most of them tended to go to safer choices think
 ing that JP would not occur again. Individuals that exhibit differences in 
 decision-making phenotypes and sensitivity have also different exposures an
 d reactions to rare and extreme events.\\n\\nContact: Philippine Escudié:Â
