Scarcity and human preference: A multi-methods investigation

Abstract: In this talk, I study the effect of resource scarcity on people’s motivations to acquire resource and avoid waste. These motivations further interact to impact people prosocial tendencies and taste preferences. I use the combination of lab experiment, field experiment, survey and secondary data to test the proposed framework.     Speaker: Professor Dai… Continue reading Scarcity and human preference: A multi-methods investigation

Causal inference with big data: an instrumental variable and model selection perspective

Abstract: In this short talk, I briefly introduce some recent work on causal inference using the instrumental variable (IV) method in high-dimensional models. Some of the common issues of the instrumental variable method, namely, weak instruments, invalid IV, control variable, and hypothesis testing, are covered selectively. Some potential empirical applications will be discussed. An R… Continue reading Causal inference with big data: an instrumental variable and model selection perspective
