Globalization and U.S. Corporate Tax Policies: Evidence from Import Competition

This paper studies how globalization affects the corporate tax policies of U.S. manufacturing firms. Using U.S.-granting China Permanent Normal Trade Relations as a quasi-natural experiment, we find a significant increase in tax reduction activities for firms facing higher exposure to Chinese imports. The effect is more pronounced for firms with higher managerial slack. We also find that the effect is stronger for firms in less diversified products market and faster changing industries. We also show that U.S. firms facing higher Chinese import competition are more likely to engage in other tax-motivated activities: acquisition of subsidiaries in low-tax regions and suspected transfer pricing. Furthermore, we explore the 2017 tax cut and the recent U.S.-China trade dispute and find that firms engage less in tax reduction activities after the 2017 tax cut and after the tariff increase for Chinese imports.

Deposit Supply and Bank Transparency

Does a bank’s dependence on different external funding sources shape its voluntary disclosure of information? We evaluate whether economic shocks that increase the supply of bank deposits alter the cost–benefit calculations of bank managers concerning voluntary information disclosure. We measure information disclosure using 10-K filings, 8-K filings, and earnings guidance. As for the funding shock, we use unanticipated technological innovations that triggered shale development and booms in bank deposits. Further analyses suggest that greater exposure to shale development reduced information disclosure by relaxing the incentives for managers to disclose information to attract funds from external capital markets.

Future Anxiety – How COVID-19 Led People to Save More Money

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.

Finance and Firm Volatility: Evidence from Small Business Lending in China

The online trading platform Alibaba provides financial technology (FinTech) credit for millions of micro, small, and medium-sized enterprises (MSMEs). Using a novel data set of daily sales and an internal credit score threshold that governs the allocation of credit, we apply a fuzzy regression discontinuity design (RDD) to explore the causal effect of credit access on firm volatility. We find that credit access significantly reduces firm sales volatility and that the effect is stronger for firms with fewer alternative sources of financing. We further look at firm exit probability and find that firms with access to FinTech credit are less likely to go bankrupt or exit the business in the future. Additional channel tests reveal that firms with FinTech credit invest more in advertising and product/sector diversification, particularly during business downturns, which serves as effective mechanisms through which credit access reduces firm volatility. Overall, our findings contribute to a better understanding of the role of FinTech credit in MSMEs.








2021中關村論壇於9月24至28日在中國北京舉辦。中關村論壇乃國家級平台,致力促進全球高科技創新交流合作。香港大學經管學院副院長林晨教授獲邀於 9月25日為金融科技平行論壇擔任主旨演講嘉賓,通過視頻就《科技信貸市場發展的一些思考》作重點分享。


研究團隊收集來自 61 個經濟體,合共超過6700間公司的數據,評估企業特質與股票收益表現,以及新冠疫情個案之間的關聯性。研究發現,儘管新冠疫情導致股票收益減少,但某些企業錄得的跌幅較為輕微,而這些企業具有以下特質:在 2020 年前公司的財務狀況較好(如擁有較多現金和未提取的信貸額、較少的總債務和短期債務,以及維持較高的利潤水準)、全球供應鏈和客戶地點受新冠疫情影響較小,積極推動企業社會責任的活動,以及較少地位穩固的高管人員。此外,家族企業(尤其是家族直接控股和僱傭職業經理人的家族企業)、大企業或政府控制的企業的股票回報表現較佳,而由對沖基金和其他資產管理公司大量投資的公司則表現遜色。在疫情期間,股票市場給予擁有較低管理層所有權的企業正面評價,卻給予擁有較高管理層所有權的企業負面評價。
