Yiyu Xing

Welcome! I am an economist at the Semel Institute for Neuroscience and Human Behavior, University of California, Los Angeles (UCLA). I am working for the Integrated Substance Use and Addiction Programs (ISAP). Prior to this, I received my PhD in economics in 2024. My research interests lie in innovation, economic history, and healthcare. My current projects center on the following two themes: 

• How do institutions and policies influence the development and diffusion of technologies? 

• What are the impacts of publicly funded technology on local productivity growth?

I am collecting and building novel historical datasets to track technology changes.
