Randomized experiments in criminology: What have we learned in the last two decades?

This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending.

Analyzing linked systems of negotiations

This article presents a conceptual framework for analyzing the structure and dynamics of what the authors call linked systems of negotiations. Even such seemingly straightforward transactions as the purchase of a family car tend to involve linked negotiations. The framework highlights the importance of internegotiation processes in shaping Zones of Possible Agreement, and proposes a typology of linkage. By mapping out and reengineering linked systems, negotiators can enhance their ability to shape the structure within which their negotiations take place.
