Measuring Political Media Slant Using Text Data
[Draft, Data appendix]
This paper explores a novel and objective measure of political media slant using the aid of natural language processing and machine learning. Implementing this approach in the institutional context of Singapore, the paper finds that The Straits Times, the flagship daily, is less accurate when quoting the parliamentary speeches of opposition politicians.
Women on Boards and Financial Outcomes: Evidence from the Singapore Exchange
In this paper, I exploit the institutional context of Singapore to estimate the effect of board gender diversity on firm performance using a sample from 2000 to 2017. To address endogeneity concerns, I instrument the number of women on board using the increase in women political participation and private firms' differential links to the government. The evidence suggest that having more women in the boardroom does not affect profitability, firm value, or systematic risk.
Women's Wave or the Blue Wave: The Me Too Movement and the 2018 U.S. Midterm Elections
[Draft, old version]
In this paper I download all tweets containing the MeToo hashtag in the year 2018 leading up to the midterm elections in November, and parse the geolocation tags of the tweeters. With the county level density measure of the tweets in 2018, I test whether the movement can explain the historic performance of women candidates in the 2018 U.S. House elections.
