All 50 U.S. states currently regulate lobbying. Data restrictions, however, limit our understanding of the relationship between legislative lobbying laws and interest group influence within the legislative process over time. A comparable measure of these laws published in the summer 2005 issue of State Politics and Policy Quarterly suggests a dynamic analysis. The early 1990s witnessed a marked increase in the stringency of state legislative lobbying regulations. This article examines how lobbying regulation impacted interest group influence across all 50 state legislatures in 1995. I then determine whether changes in a state's regulations affected interest group influence over time from 1990 to 1995. Evidence suggests that increased regulation reduces influence both across and within states over time.
The Clean Air Act (CAA) controls routine emissions at petroleum refineries, by creating limits and penalties for excess emissions. The CAA offers provisions for upset events, air emissions released because of unforeseen or unavoidable circumstances, if companies report the emissions and take corrective action. States enforce upset event rules and many states provide exemptions for a variety of circumstances, which may allow upset emissions to become a substantial, yet mostly unregulated source of emissions. We catalog the quantity and type of emissions generated during upset events at 18 Texas petroleum refineries from 2003 to 2008. We find that upset events occur frequently at these facilities and are collectively large in magnitude, emitting a combined total of 75 million lbs of emissions. In a select number of cases, single upset events exceeded annual emissions reported to the Toxics Release Inventory. Future research should assess the accuracy of upset event reporting and impact of upset events on environmental health.
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.
