题目:Institutional Investors and Corporate Environmental Innovation

摘要:This paper addresses whether institutional investors drive the innovation direction of corporates toward environmentally friendly technologies. Using environmental patents filed by Chinese publicly-listed firms in the manufacturing and public utility sectors during the 2003-2016 period, we find the positive relationship between shareholding ratios of institutional investors and corporate environmental innovation. Institutional investors lead to a higher ratio of environmental patents in total patents for corporates in the pollution-intensive sector than those in the non-pollution-intensive sector. Institutional investors exert the roles of financial support and corporate governance in pursuit of monitoring corporate’s long-term sustainable innovation. Lastly, institutional investors are motivated by financial returns. They experience a higher return on corporate market value from the induced environmental innovation.

题目:Information Acquisition and Usage of Retail Investors: Evidence from Web Views and Watchlists

摘要:We use a novel large data set of Chinese retail investors to study their information acquisition and usage activities. On the one hand, retail investors are more likely to collect information of attention-grabbing stocks, consistent with the view that they are unsophisticated. On the other hand, retail investors appear to utilize information with discretion in making investment decisions, consistent with the view that they have skills. Stocks that are selected more often following information acquisition by retail investors tend to be easier-to-value, have good future news, and earn higher returns even after controlling for stock characteristics.

题目:Superstition and the Stock Market: Evidence from Lunar Bogey

摘要:Superstition affects investors’ cognition, judgment, and investment behavior. We utilize the traditional Chinese Almanac to construct the Lunar Bogey Index (LBI). Results show abnormal returns in stock markets associated with the LBI. This superstition effect is stronger in stocks with a higher limit of arbitrage and during bear-market periods and remains robust to diagnostic tests. The data are consistent with investors’ psychological biases in trading activities.

题目:Do the Hype of the Benefits from Using New Data Science Tools Extend to Forecasting Extremely Volatile Assets?

摘要:This paper first provides an illustration of the benefits of using machine learning for forecasting relative to traditional econometric strategies. We consider the short-term volatility of Bitcoin market by realized volatility observations. Our analysis highlights the importance of accounting for nonlinearities to explain the gains of machine learning algorithms and examines the robustness of our findings to the selection of hyperparameters. This provides an illustration of how different machine learning estimators improve the development of forecast models by relaxing the functional form assumptions that are made explicit when writing up an econometric model. Our second contribution is to illustrate how deep learning can be used to measure market level sentiment from a 10% random sample of Twitter users. This sentiment variable significantly improves forecast accuracy for every econometric estimator and machine algorithm considered in our forecasting application. This provides an illustration of the benefits of new tools from the natural language processing literature at creating variables that can improve the accuracy of forecasting models.

题目:Do Mobile Payment Platforms Compete with Each Other? Evidence from a Bank in China

摘要:This paper estimates the effect of additional mobile payment access on spending patterns among Consumers in China. Based on a unique dataset of users’ credit card transactions from a large foreign bank in China, we find that new mobile payment users’ monthly consumption frequency increases by 3.75 percent relative to existing users when a prominent mobile payment method, WeChat Pay, is introduced to customers. We also find that the increase in consumption mainly occurs in low-value durables goods. Moreover, after investigating potential impacts on different payment channels, we find that the newly added WeChat Pay serves as a substitute to physical cards but a complement to other mobile payment methods.

题目:The gender gap in financial distress

摘要:We examine the gender gap in personal financial distress in the United States. Using a representative sample of households, we find that women are 39.95% more likely to default on debt payments, 37.58% more to default on bill payments, and 30.63% more to experience foreclosure, repossession, or bankruptcy than men. We provide evidence that susceptibility to adverse income shocks and suboptimal financial choices are two underlying mechanisms, with the latter accounting for a higher proportion in the identified gender gap than the former. We mitigate endogeneity concerns by controlling for sibling fixed effects.
