The gray band is an 8% interval around a sine wave with period 56 years. The black dots and black triangles show what happened after the graph was first put together in 1988.[7] Presently we are entering a “spring” season. WWI occurred in late “summer” whereas WWII in late “winter”.

Llad Phillips51 Questions About Crime _ Why is it difficult to empirically demonstrate the control effect of deterrence on crime? _ What is the empirical evidence that raises questions about deterrence? _ What is the empirical evidence that supports deterrence?

Llad Phillips52 Evidence Against the Death Penalty Being a Deterrent _ Contiguous States _ Maine: no death penalty _ Vermont: death penalty _ New Hampshire: death penalty _ Little Variation in the Homicide Rate _ Source: Study by Thorsten Sellin in Hugo Bedau, The Death Penalty in America

Ehrlich Results: Elasticities of Homicide with respect to Controls Source: Isaac Ehrlich, “The Deterrent Effect of Capital Punishment

Llad Phillips56 Critique of Ehrlich by Death Penalty Opponents _ Time period used: _ period of declining probability of execution _ Ehrlich did not include probability of imprisonment given conviction as a control variable _ Causal variables included are unconvincing as causes of homicide

Llad Phillips59 What is the Empirical Evidence that Supports Deterrence? _ Domestic violence and police intervention _ Experiments with control groups _ Traffic Black Spots _ Focused enforcement efforts

Llad Phillips60 Traffic Black Spots _ Blood Alley _ Highway 126 _ San Marcos Pass _ Highway 154

Llad Phillips91 Police Intervention with Experimental Controls _ A 911 call from a family member _ the case is randomly assigned for “treatment” _ A police patrol responds and visits the household _ police calm down the family members _ based on the treatment randomly assigned, the police carry out the sanctions

Llad Phillips92 Why is Treatment Assigned Randomly? _ To control for unknown causal factors _ assign known numbers of cases, for example equal numbers, to each treatment _ with this procedure, there should be an even distribution of difficult cases in each treatment group

Llad Phillips94 Part II Optimization of the Criminal Justice System

Llad Phillips95 Questions About Statistical Studies of Deterrence _ Do we know enough about the factors that cause crime? _ Can we find variables that will control for variation in crime generation? _ We have better measures for the factors that control crime than for the factors that cause crime. _ Unknown variation in crime generation may mask the effects of crime control.

Llad Phillips101 Optimization of the Criminal Justice System (CJS) _ Minimize damages to victims plus the costs of control, subject to the crime control technology _ damages to victims per capita = loss rate per offense * offense rate per capita _ Costs of control = per capita expenditures on CJS _ Total cost = damages + expenditures
