Public productivity, in particular the efficiency of public expenditures, has been a subject of academic and nonacademic debate for a long time. A number of studies have been conducted over the years on the subject using mostly conventional statistical methods such as production functions and occasionally using techniques such as data envelopment analysis (DEA). Most of these studies were conducted at a microlevel using a single decision unit with limited data. This study uses a multistage DEA to analyze public productivity using panel data for all fifty states of the United States over a twenty-one–year period. Based on well-known Farrell’s technical efficiency, the study measures productivity using both constant and variable returns to scale. The results of the study show that there has been a general decrease in efficiency during the study period, with some exceptions, consistent with the growth trend in the national economy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
