In this research project, the PIs investigate the possibility that social rationality explains the emergence of one type of bubble in competitive asset markets: a bubble referred to as a "credit market bubble." The bubble is defined as a situation where (i) the debt is priced above its commonly known intrinsic value and (ii) the debt is rolled over even though each creditor should cash in because everyone knows that the debtor will never be able to repay. Building on evidence from behavioral game theory, the PIs conjecture that such credit market bubbles emerge whenever the debtor's payment ability, although never sufficient, grows over time. Pilot experimental data confirm the emergence of bubbles in this setting. The researchers will conduct experiments to further examine the robustness of bubbles in this environment and test the hypothesis that norms are driving the observed behavior.In terms of broader impacts, this research will provide a better understanding of price bubbles. Credit bubbles and accompanying asset price run-ups re-occur with alarming frequency in the real world. This research suggests that tension between individual and social rationality is the root cause for their existence. It will lead to a better understanding of this ubiquitous phenomenon in modern capitalist society, and inspire novel and effective government policy and regulation to minimize their negative effects.

在这个研究项目中，pi调查了社会理性解释竞争性资产市场中出现一种泡沫的可能性：一种被称为“信贷市场泡沫”的泡沫。泡沫被定义为一种情况，即：(1)债务的定价高于其众所周知的内在价值，(2)债务被展期，尽管每个债权人都应该兑现，因为每个人都知道债务人永远无法偿还。基于行为博弈论的证据，pi推测，每当债务人的支付能力（尽管从未足够）随着时间的推移而增长时，这种信贷市场泡沫就会出现。试点实验数据证实了在这种情况下气泡的出现。研究人员将进行实验，进一步检验泡沫在这种环境下的稳健性，并检验规范驱动观察到的行为的假设。就更广泛的影响而言，这项研究将更好地理解价格泡沫。在现实世界中，信贷泡沫和随之而来的资产价格上涨以惊人的频率再次出现。这项研究表明，个人理性与社会理性之间的紧张关系是他们存在的根本原因。这将有助于更好地理解现代资本主义社会中普遍存在的这一现象，并激发出新颖有效的政府政策和法规，以尽量减少其负面影响。
