Religion plays an important role in the lives of many Americans, but up until now economists have done relatively little research on the implications of religiosity and its effect on economic outcomes. In an important series of new papers, MIT economist Jonathan Gruber has explored the factors that drive religious participation and the impact of that participation on levels of education, income, welfare participation, marriage, and divorce. Mr. Gruber will present his findings at this conference, and Len Burman and Charles Murray will respond.
