| Research Abstract |
This research implemented an empirical analysis of social interactions about adolescent delinquencies. Firstly, I employed a matching theory to describe friendship formation among young adults, and modeled it as a one-sided non-transferable utility game. I discovered necessary conditions to estimate an econometric model of the game with multiple predictions of stable matching. Secondly, I developed a new distanced-based test to detect localization of knowledge spillovers. Using the test, I computed the distances within which knowledge spillovers are localized. The distance of localization can be used as a basis to delineate the scope of local interactions among young adults when committing delinquent behaviors. Lastly, I construct a linear-in-means social interaction model that describes simultaneous decisions of making friends and committing delinquent acts. I estimated the structural model to gauge peer effects on youth behaviors of smoking, alcohol drinking, and illicit drug taking.
