Using a comprehensive approach, we investigate how various forms of non-displayed order flow such as hidden orders on exchanges, brokerage internalizations, and orders submitted to off-exchange venues affects price efficiency. By considering the multiple forms of dark trading available to traders, we are able to better understand the nuances of dark trading, its impacts on price efficiency, and mitigate the unobserved variable problems present in studies that examine only one aspect of dark trading. We find that hidden orders on exchange have a deleterious impact on price efficiency. The impacts of other types of pre-trade, non-displayed orders on price efficiency is more nuanced.

Using Roberts (2015) loan-level data from 2000 to 2011, we find that the inception of CDS trading on reference firms’ debt is associated with a decreased number and lower probability of amendments, restatements, and rollovers to existing lenders of bank loans. Reference firms are also less likely to terminate loans prematurely or refinance with different lenders after the inception of CDS trading and tend to exhibit longer loan maturities. Our evidence is consistent with the empty creditor problem arising from CDS trading and the resulting decrease in the negotiation power of borrowers. Our research contributes to understanding how financial innovations alter bank-lending relationships.

We hypothesize that financial risk-taking originates in preindustrial interpersonal population diversity. We use data on immigrants residing in the United States and show that controlling for all known determinants of portfolio decisions and more than 100 control variables, diversity in the country of immigrants’ origin positively affects stock market participation and the level of risky asset holdings. Our results remain robust when instrumenting diversity with plant variety. We also identify the channels through which the effect of diversity operates (mostly individualism and human capital), but also conclude that diversity exerts an independent effect.

Using the geographic location data of 218,554 commercial bank branches in China, we find that an increasing number of bank branches in the vicinity of enterprises, namely bank competition, leads to higher corporate employment, particularly for non-SOEs and SOEs with less government influence. Channel analyses reveal that better access to banking facilitates information extraction and eases credit constraints for surrounding firms, which thus increases labor investment. In addition, fintech development moderates the positive effect of bank competition on corporate employment. An exogenous policy shock as well as two instrumental variables, are used to correct for endogeneity and our results remain consistent. The findings are also robust to alternative samples, proxies, and different fixed effects. Further analyses show that bank competition improves firms’ labor investment efficiency and upgrades their employment structures. Lastly, increased employment improves the firm performance of non-SOEs.
