Welcome
I am Zhi Hao, a PhD candidate in economics at Columbia. My research lies at the intersection of behavioral, experimental, and labor economics. One strand examines what motivates workers and how information preferences shape their behavior, while another investigates the cognitive foundations of framing effects. I also study the design and evaluation of conservation policies. I employ field and lab experiments to address these questions.
