Youth Gangs: A 1990s Perspective

The juvenile gang in the 1990s differs in many significant ways from the gangs described in the “classical” gang studies of the 1950s and 1960s. Juvenile justice professionals should be aware of the changes in the nature, organization, motivation, and activities of gangs and plan intervention strategies accordingly. One important issue in gang research—one which has great implications for public policy—is defining “gang” and “gang-related crime.” The existence of a “gang problem” in a community may be more related to the definition of “gang” and “gang-related” than to the objective issue of whether, or not, a gang problem exists. Further issues relating to the gang of the 1990s involve changing age and sex distribution of gang members, increasing violence by gangs, and deeper involvement with drug distribution. Implications for public policy are discussed.     

Should rules be simple?

The principal argument of the paper is that in an incomplete information setting, where the private sector lacks information of government objectives and has to learn about the policy rule by direct observation and estimation, simple ‘sub-optimal’ rules may outperform the more complicated rule which is optimal under complete information. This result is demonstrated by simulations using an overlapping contract rational expectations model. The paper thus provides some formal reasoning to support arguments for simplicity associated with credibility and the need for the private sector to be able to monitor policy.
