(1)Patterns of regional job search and job posting behaviours R&R at Regional Studies

   Abstract: This study examines the evolution of local labour supply and demand. We develop job search indices and employ high-frequency job-posting data to proxy local labour supply and labour demand, respectively. We
find that state aggregate job search and job posting behaviours are highly synchronised, which is partially due to macroeconomic fluctuations and increasingly widespread use of internet job searches. Moreover, we find that both aggregate and state-specific job searches are countercyclical, whereas job postings are procyclical; the former is
contrary to theoretical prediction. We observe that wealth and precautionary effects lead job seekers to search more during economic downturns.

(2)Public News and Market Liquidity: Evidence from the CDS Market (joint with Xinjie Wang, Shanxiang Yang, Jinfan Zhang, and Zhaodong (Ken) Zhong) R&R at JBF

  Abstract: This paper examines the effects of public news releases on the market liquidity in one of the most important OTC derivative markets—the CDS market. We document that, at the time of news releases, the bid-ask spread is wider, the number of quotes is larger, and the number of dealers is greater. Earnings announcements have particularly strong effects on liquidity while credit ratings have no significant effects. Moreover, the bid-ask spread only increases on news release days and reverts to normal levels several days after news releases. Finally, the effect of news on liquidity is stronger for negative, fundamental, and unscheduled news, and is more pronounced among firms with higher information asymmetry. Our findings are consistent with models of rational trade in Kim and Verrecchia (1994).

(3)Lobbying activity over business cycles

  Abstract: This study investigates how firms’ lobbying activities change over business cycles. Using data from the Center for Responsive Politics, we show that firms are more likely to participate in and incur greater expenditure on lobbying in times of recessions. Furthermore, non-lobbying firms are more likely to start lobbying during recessions. Wefurtherexplore two channels for this result: financial constraints and executive’s motivation. Because recession causes the external financing environment to deteriorate, we show that firms facing more constraints because of recessions lobby more. Moreover, executives have stronger motivation to lobby during recessions because doing so helps them to obtain more personal compensation.
