中文摘要
政府对金融中介机构的持股在世界各地普遍存在。在本研究中,我们考察券商与上市公司之间共同的政府所有权对券商信息生产职能的影响。我们表明,关联分析师往往对由控制其所在券商的同一政府主体所控制的公司股票发布更为乐观的推荐意见。这种乐观偏差在经济冲击时期尤为显著。我们利用中美贸易战期间新增的关税征收与关税豁免分别作为外生的负向冲击和正向冲击来证明这一点。此外,我们的研究表明,政治关联分析师推荐的股票往往表现不及独立分析师推荐的股票,这意味着乐观情绪源于利益冲突而非更优的信息。进一步地,我们的研究强调,成熟投资者能够察觉这种潜在偏差并将其纳入交易决策。与“互惠交换”的解释相一致,政治关联券商在地方政府债券发行中获得更大的分配份额,而当这些关联券商进行增发时,政府则会认购更多股份。
Abstract
Government ownership of financial intermediaries is pervasive around the world. In this study, we examine the impact of common government ownership between the brokerage and listed firms on the information production role of brokerage firms. We show that affiliated analysts tend to issue more optimistic recommendations for stocks of firms controlled by the same government entity that controls their brokerage firms. This optimistic bias is particularly pronounced during periods of economic shocks. Our study demonstrates this by utilizing additional tariff impositions and tariff exemptions during the U.S.–China trade war as exogenous negative and positive shocks, respectively. Additionally, our study indicates that stocks recommended by politically affiliated analysts tend to underperform those recommended by independent analysts, implying that the optimism stems from conflicts of interest rather than superior information. Furthermore, our research highlights that sophisticated investors perceive the potential bias and incorporate it into their trading. Consistent with an exchange of favors story, politically affiliated brokerage firms receive a larger allocation during the issuance of local government debt, whereas governments subscribe for more shares during seasoned equity offerings by these affiliated brokerage firms.
