Teams Make You Smarter: Learning and Knowledge Transfer in Auctions and Markets by Teams and Individuals

We study the impact of team decision making on market behavior and its consequences for subsequent individual performance in the Wason selection task, the single-most studied reasoning task. We reformulated the task in terms of "assets" in a market context. Teams of traders learn the task’s solution faster than individuals and achieve this with weaker, less specific, performance feedback. Some teams even perform better than the best individuals. The experience of team decision-making in the market also creates positive knowledge spillovers for post-market individual performance in solving new Wason tasks, implying that team experiences enhance individual problem-solving skills.team decisions, markets, auctions, Wason selection task, rationality

Teams Make You Smarter: How Exposure to Teams Improves Individual Decisions in Probability and Reasoning Tasks

Many important decisions are routinely made by transient and temporary teams, which perform their duty and disperse. Team members often continue making similar decisions as individuals. We study how the experience of team decision-making affects subsequent individual decisions in two seminal probability and reasoning tasks, the Monty Hall problem and the Wason selection task. Both tasks are hard and involve a general rule, thus allowing for knowledge transfers, and can be embedded in the context of markets that offer identical incentives to teams and individuals. Our results show that teams trade closer to the rational level, learn the solution faster, and achieve this with weaker, less specific, performance feedback than individuals. Most importantly, we observe significant knowledge transfers from team decision-making to subsequent individual performances that take place up to five weeks later, indicating that exposure to team decision-making has strong positive spillovers on the quality of individual decisions

Synergistic Effects of GDNF and VEGF on Lifespan and Disease Progression in a Familial ALS Rat Model

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of motor neurons in the brain and spinal cord. We have recently shown that human mesenchymal stem cells (hMSCs) modified to release glial cell line-derived neurotrophic factor (GDNF) decrease disease progression in a rat model of ALS when delivered to skeletal muscle. In the current study, we determined whether or not this effect could be enhanced by delivering GDNF in concert with other trophic factors. hMSC engineered to secrete GDNF (hMSC-GDNF), vascular endothelial growth factor (hMSC-VEGF), insulin-like growth factor-I (hMSC-IGF-I), or brain-derived neurotrophic factor (hMSC-BDNF), were prepared and transplanted bilaterally into three muscle groups. hMSC-GDNF and hMSC-VEGF prolonged survival and slowed the loss of motor function, but hMSC-IGF-I and hMSC-BDNF did not have any effect. We then tested the efficacy of a combined ex vivo delivery of GDNF and VEGF in extending survival and protecting neuromuscular junctions (NMJs) and motor neurons. Interestingly, the combined delivery of these neurotrophic factors showed a strong synergistic effect. These studies further support ex vivo gene therapy approaches for ALS that target skeletal muscle
