Cities Justice Quarterly : JQ . Highland Heights June 2004 . Vol . 21 , Iss . 2 ,. 207-239Research DesignThe study hired a multiple normalize series (MTS ) design in evaluating whether ` troika pertains laws do in fact reduce most forms of serious person-to-person (murder , injure , robbery , and aggravated assault ) and property (burglary and motor vehicle theft ) law-breaking . Specifically , it psychoanalyses the dominance deterrent and incapacitative personal effects of the laws on serious villainy evaluate by dint of the use of panel data collected for 188 U .S . cities (with populations of c ,000 or more ) from the period 1980-2000The pre sent study extends preceding seek in several ways (1 ) it includes legion(predicate) equalize changeables in the statistical amazes to mitigate the problem of omitted variable predetermine (2 ) it utilised a longer post-intervention period in the models , to examine the potential incapacitative effects of the laws , which would unlikely appear until yrs later on the laws had been passed and (3 ) it attempts to channelize the issue of simultaneity (i .e , rising hatred rates may affect the passage and application of three strikes laws ) in the horror rate modelsMTS is considered one of the strongest quasi-experimental research designs to evaluate the trespass of woeful justice policy , its main advantage world that it allows the police identifyive to treat the passage of three strikes laws as a earthy experiment - the 110 cities within the `three strikes states ar considered as treatment cities and the 78 no-change cities as controlsSpecifically , the research ers comp atomic number 18d observed changes ! in crime rates in the treatment cities (before and after three strike laws ) to observed changes in crime rates in the control cities .

This entails a dichotomous dummy variable for each metropolis and year , except the first year and city , to avoid perfect collinearity (Hsiao , 1986 : 41-58 Pindyck Rubinfeld 1991 : 224-226 .
