Rewards and Consequences: Redistricting on the Chicago City Council

The challenges of understanding gerrymandering are primarily related to its conceptual ambiguity and measurement. This is true despite landmark legal rulings and a rich literature on the subject. In an attempt to alleviate some of the confusion, theories of the gerrymandering process are combined with advanced quantitative and mapping techniques. The focus is on Chicago, where it is frequently claimed that gerrymandering is institutionalised; however, there has not been sufficient study of the causal connections between gerrymandering and a ward’s racial makeup. Employing a mixed methods approach which combines a case study of the 2011–2012 redistricting in Chicago with quantitative analysis of Decennial Census and data from the Chicago Data Portal, this article examines the remapping of Chicago from early 2012 (effective in 2015 and matched with 2010 Census data) to assess how potentially gerrymandered districts are diluting or concentrating vote share of racially homogeneous groups.     

International Dimensions: What Is the Role of Third Parties?

In the Arab–Israeli arena, third parties have traditionally played a prominent role. External intervention has tended to peak when violence threatens international interests (e.g., the 1973 Arab–Israeli War), or when the parties are unable to sustain a negotiating process. Whether providing political and security assurances aimed at mitigating insecurity or offering economic inducements to underwrite peace accords, third parties have made a number of positive contributions toward managing the conflict.     

The triumph of regulatory politics: Benefit–cost analysis and political salience

While benefit–cost analysis (BCA) is now a permanent part of the regulatory process in the United States, and many other countries around the world as well as the European Union have adopted it or are moving toward it, there have been few empirical attempts to assess either whether its use improves regulations or how BCA interacts with the political environment. We use a unique US database of the costs and benefits of 109 economically significant regulations issued between 2000 and 2009 to examine whether the amount of information provided in the BCA or political factors surrounding the regulation better correlate with the net benefits of the regulation. We find that there is little correlation between the information provided by the analysis and the net benefits. However, we find that regulations that receive few public comments and are not issued at the end of an administration, have the highest net benefits. These are the regulations that are the least politically salient. This interaction between the political environment and the economic performance of a regulation has been under‐examined and deserves further study.     

Equity and information: Information regulation,environmental justice,and risks from toxic chemicals

Decreases over time in pounds of industrial chemical emissions have led to concerns that nonminority, higher‐income communities have benefited disproportionately in reductions in risk. Toxic chemical release data, modeled for toxicity and dispersion in square kilometer units across 45 states, are used to test six sets of hypotheses of potential interactions between facilities and the communities surrounding them. The results provide mixed evidence that ethnicity explains chemical emission changes. Stronger support is found that changes in emission patterns are affected by a community's ability to process complex information and its capacity for collective action, and industrial production factors. Some support is found for the efficacy of state environmental policies that both do and do not fit the traditional regulatory model in encouraging risk reductions. © 2005 by the Association for Public Policy Analysis and Management
