摘要：
Source preference is evident when identically distributed risks from different sources of uncertainty are not valued the same (Heath and Tversky, 1991). This has been axiomatized in Chew and Sagi (2008) and investigated experimentally in several follow up papers including Abdellaoui et al. (2011). Using a trailing digit betting design in four experiments, we identify familiarity bias in source preference as an explanation for home bias in international finance that is distinct from ambiguity aversion or informational advantage. The first two studies establish the existence of a strong familiarity bias within an investment context. A third experiment establishes that standard home bias and familiarity bias are of comparable magnitudes. The last study further demonstrates that home bias can be explained, within subject, by familiarity bias but not by ambiguity aversion. The studies consistently point to familiarity bias as a driver of home bias across investment context and subject types.

摘要：
This paper documents the response of the within-household labor supply to the economic uncertainty in China. Using a wave of massive layoffs at state-owned enterprises (SOEs) in 1997 as a natural experiment, we show that the spouses of the household heads who worked at an SOE increased their labor supply following the layoffs significantly more than the spouses of the household heads who did not work at an SOE. We explore two possible explanations for this finding. The precautionary motive seems to largely explain the main effect— though the head of the household was not laid off (“worriers”), the family exhibit less consumption and increase precautionary savings. Suggestively, the substitution effect also drives the main effect as the heads of households who left their positions at SOEs during the layoffs (“leavers”) tend to migrate to jobs that required few skills and paid less.

摘要：
Regulatory independence forms a foundation for modern financial systems. The institutions’ value is illuminated by a Progressive Era policy experiment when independent state-bank regulators came under governors’ supervision. Afterwards, bank resolution rates declined during gubernatorial election campaigns for banks supervised by state but not national authorities. This gubernatorial-campaign effect diminished by two orders of magnitude, but did not disappear, after the FDIC became the independent resolver for all insured banks in 1935. In addition, during the Progressive Era, declines in bank resolutions led to declines in business bankruptcy rates, an effect that is not observed in the FDIC era. Our findings indicate regulatory independence can dramatically reduce but may not eliminate politics’ impact on banks and the economy.
The Great Depression illustrates the importance of financial independence. New research indicates that onset of banking panics in the United States in the fall of 1930 occurred in the aftermath of the gubernatorial elections in Tennessee and New York. In these states, regulators suppressed information about weaknesses in critical nodes in the financial network. In days after the election, regulators shut down banks at these critical nodes, triggering counterparty cascades that forced hundreds of financial institutions out of operation and triggering panics among depositors and bankers that spread the crisis to areas far from the regions where the panics began.

摘要：
This paper proposes two easy-to-implement nonparametric tests for the equality of two conditional distributions. To avoid estimating conditional density functions, we transform the null hypothesis into an equivalent characterization. Based on two-sample U-process and weak convergence theory, we construct the Kolmogorov-Smirnov (KS) and Cramér-von Mises (CvM) statistics and find their asymptotic distributions. The critical values are constructed by a multiplier bootstrap method. The proposed KS and CvM tests are proved to be asymptotically size-controlled and consistent against each fixed alternative. A study on the local power of the tests is provided. Monte Carlo experiments illustrate good performance of the tests in finite samples.

摘要：
We use Chinese customs data to show that unofficial non-tariff barriers were responsible for 50\% of the overall reduction in Chinese imports from the U.S. during the height of the U.S.-China trade war in 2018 and 2019. We infer non-tariff barriers from the change in imports of U.S. products relative to imports from other countries of the same HS-6 product, after controlling for the change in the relative price of U.S. imports to the same product sold by other countries. Non-tariff barriers were imposed on a small number of agricultural products, did not apply to state-owned importers, and larger for products with a high share of state importers in total imports. Non-tariff barriers were responsible for more than 90\% of the welfare cost to Chinese consumers of the U.S.-China trade war. The welfare loss to China of a given reduction in imports from the U.S. from non-tariff barriers is about six times larger than an equivalent import decline due to higher tariffs. Non-tariff barriers are more costly compared to tariffs because they applied to some importers and not others, which results in misallocation, and because non-tariff barriers do not generate revenues.

摘要：
2015年《巴黎协定》在第21届联合国气候变化大会上通过，成为全球气候治理进程中新的里程碑。然而气候协定中的国家自主贡献、资金机制和全球盘点在没有强制的情况下是否有效仍存在争议。本研究基于带阈值的公共品博弈模型，通过均衡分析、演化博弈、行为实验和计算机仿真结合的方法，分析了气候协议中资金机制对合作减排的促进作用。理论和实验结果表明即使在没有强制的情况下，富国也会自愿通过资金机制资助穷国减排，穷国受到激励后也相应提高了减排量，进而达到了减排目标；此外，富国出钱穷国出力的合作减排方式不仅具有更强的演化稳定性，并且还能够帮助提高双方的收益；这些结论对不同的减排周期、减排成本比和气候风险具有鲁棒性。
