Party Differentiation in Congress

Abstract At times, the American political parties are so close in terms of policy positions that critics denounce the lack of a “dime's worth of difference” between them. At other times, the gap between them on a left‐right dimension is huge. How can we explain this variation? We argue that parties can behave rationally as collective units, and that shifts in divergence and convergence can be explained as rational responses to changes within governmental institutions and to shifts in conditions outside. We analyze this argument using adjusted ADA scores (Groseclose, Levitt, and Snyder 1999) to compare voting score differences between the Democratic and Republican parties in Congress from 1952 to 1996. We pose specific hypotheses for potentially important factors shaping party behavior and test them with a multivariate model. Our results support the argument that the variation in the behavioral gap between the two parties in Congress can be explained as rational party responses to internal and external stimuli.     

Does Institutional Structure Effect Public Health Expenditures?

This paper explores supply‐side costs and institutional structure in a shared authority state public health system. It is found that in a shared governance public health system, intermediary district structure influences the movement of limited resources to serve populations and persons most in need. This early empirical test suggests that policy making and public administration concerning public health expenditures in a shared governance system are in a practical sense local, but decisions made at the intermediary level by regional district administration are an important influence on local public health expenditures.
