This book will test hypotheses relevant for ethnic §community, social capital, and rational actor §theories to explain religious participation among US §immigrants. In this work, I provide an overview of §the theoretical perspectives that will guide my §research. Ethnic community and social capital §theorists have suggested that religious §organizations constitute important social capital §resources that generate cultural and economic §benefits. The size and location of the ethnic §community may also play a significant role in §religious participation among immigrants. Immigrant §and ethnic communities can play a normative role by §enforcing participation through possible sanctions §and restricting access opportunities. Participation §in such situations may become semi-involuntary. §Immigrant religion may also be fruitfully explored §using market theories from the demand and the supply §side. These theories examine the preferences and §constraints of individuals making religious choices, §and also the structure of market offerings in the §origin and destination nations that constitutes the §religious supply.
