I have been involved in several projects to construct measures of  a number of concepts and constructs that are not ofter measured in economics, ranging from subjective expectations, to parental beliefs, to bargaining power within couples, to tastes for hypothetical allocations of resources. I have also worked on how to use optimally existing instruments. The relation between economic theory and measurement was the theme of my presidential address to the Econometric Society in 2020.

I have been interested in models and tests of imperfect risk sharing in a variety of different contexts. I have worked on tests of perfect risk sharing and on the interpretation of results indicating rejections of the perfect risk sharing. In particular, I have worked with models with moral hazard, with imperfect information in networks and models with imperfect risk sharing.
