Mark E. Votruba, PhD (Economics), receives National Science Foundation grant to study disability insurance use and the role of social interaction effects

By | September 10, 2004

The two-year project aims to measure the magnitude of social interaction effects in DI use among neighbors, i.e. the extent that DI use among one`s neighbors affects one`s own decision to enter disability. Dr. Votruba is joined on this project by Co-PI Mari Rege (PhD, Economics), a colleague in the Economics Department at Weatherhead School of Management. The researchers will take advantage of a comprehensive longitudinal dataset (employment, socioeconomic, geographic, and program participation information for every person in Norway since 1992) to implement a novel instrumental variables strategy. Under this strategy, the magnitude of social interaction effects will be estimated using the relationship between past employment shocks and the current DI participation rate in a neighborhood.
