We examine how investor demand for leverage shapes asset management fees. We show that in the sample of U.S. equity mutual funds: (1) fees increase in fund market beta precisely for beta larger than one; (2) this relation becomes stronger and high-beta funds experience larger inflows when leverage constraints tighten; and (3) low net alphas are especially common among high-beta funds. These results are consistent with a model in which asset managers compete for leverage-constrained investors with heterogeneous risk aversion. The asymmetric relation between betas and fees also extends to the HML and SMB factors.

Take the recent study by Chen Lin and Mingzhu Tai from the HKU Business School, conducted with collaborators from the University of California, Berkeley and the Chinese University of Hong Kong. Their paper addressed a fundamental worry for almost everyone during the pandemic: Money. Specifically, they examined how people in the U.S. saved money in response to COVID-19.

为什么在疫情期间会有大量存款汇入银行？我们发现，银行分行若位于2019冠状病毒病感染率较高的地区，它们的存款利率较位于感染率较低的地区的银行分行（即便是隶属同一家银行集团）为低。信贷提取、国家政策（如薪资保护计划）以及避险措施并非导致这些银行分行之间出现存款利率变化的原因。证据显示，2019冠状病毒病感染率较高的地区与当地民众对其就业前景和收入减少的焦虑有连带关系，导致民众减少支出和增加银行存款。
