Resource economists have greater access to large sets of data today because of advances in information technology. Data collected over time are known as “longitudinal” or “panel” data. My research centers on developing statistical methods to analyze longitudinal data as accurately as possible so that economists can better understand cause-and-effect relationships. Economists can use the quantitative methods I develop to evaluate the impact and relevance of various policies. For example, an economist could examine longitudinal data collected before and after a new crop subsidy is introduced in order to determine its effect on farmers.
In addition, I use statistics to analyze environmental issues. Recently, for example, we examined whether local governments in China manipulate their air quality data—a public concern at the international level.
