  In the United States, immigration policies are politically debated when the concern is about the effect of such policies on crime and labor market outcomes. Even though the concern for crime exists for a long time, such concern is intensified due to rise in crime and the contagious behavior of crime in United Sates. Therefore, the primary objective of this dissertation is to investigate the causal effect of different immigration policies on crime and labor market outcomes in the context of United States. In addition, contagious behavior of crime along with the effects of different socio-economic and socio-demographic factors on crime are also examined in the context of US by allowing for county-level spatial dependence. The first chapter investigates statistically, the sanctuary policy (implemented on different US counties) effect on broad categories (i.e., violent and non-violent crime) and subcategories (i.e., murder, rape, burglary, motor vehicle (MV) theft) of crime from the lens of different causal methods. The analysis is conducted considering US county-level panel data and by applying different variations of difference in differences (DID) and synthetic control methods. A further analysis of sanctuary policy effects on crime is conducted by applying both the methods in a staggered treatment adoption setting. The results found that, even though there are few significant rises in crime categories due to sanctuary policy implementation, most of the results indicate that there is no evidence of statistically significant effect of sanctuary policy on different crime categories.....

  Chapter two of the dissertation focuses on the contagious/spilling behavior of crime along with investigating the linkages in between violent and non-violent crime in United States. methods. The key findings suggest positive causal effect of DACA on DACA-eligible individual’s labor market outcomes where DACA-ineligibles face bigger detrimental effects on their labor market outcomes due to DACA induced labor supply shock.
