臺大場次講題：Causal Inference in Action: Basic Concepts, Applications, and Limitations
演講介紹：Causal inference has become increasingly popular in a variety of social sciences. This seminar provides an introduction to causal analysis in social sciences. We discuss why causal inference is distinct from the associational analysis, review popular identification approaches include instrumental variable, difference in difference, matching, synthetic control, and fixed-effect model. We also highlight their limitations. The participants of this seminar are expected to bring their own projects and consider how to apply the ideas in their own analysis.
政大場次講題：The Inequality Consequences of Immigration
演講介紹：This research examines the potential impact of immigration on the wage distribution in the United States. Departing from the focus on the competition at the bottom, we examine how immigrants may complement native workers at the middle and top of the wage distribution. While there is some evidence indicating that an increased presence of low-skilled immigrants is associated with wage losses for low-skilled natives, we find that a similar competition is neither observed between high-skilled immigrants and natives at the upper end nor within high-skilled occupations. Instead, the presence of foreign-born workers, whether high- or low-skilled, is associated with substantial gains for high-wage natives. Consequently, increased immigration is associated with rising levels of inequality
