Review for the Final: I Concepts and Analytics
Part ICoordinating the Components of the Criminal Justice SystemPart IIThe Serious Offender
Questions About Crime • Can we explain trends in crime and trends in expenditure on the criminal justice system? • What is the right mix of enforcement and corrections?
Schematic of the Criminal Justice System “The Driving Force” Causes ?!! Weak Link Offense Rate Per Capita Crime Generation Expected Cost of Punishment (detention, deterrence) Expenditures Crime Control
Conclusions • Causal conditions continue to get worse • As a consequence we have to spend more real dollars per person to keep crime levels from rising • Crime acts like a tax • Californians spend $450 (1992$) per person on criminal justice to keep things from getting worse
Question • What happened around 1980 to differentiate the 50’s, 60’s, and 70’s from the 80’s and 90’s? • was there a change in behavior? • was there a change in policy?
Law Enforcement Prosecution Courts Public Defense State Prisons Other Corrections
Abstraction (Model) of the Criminal Justice System New Admits Enforcement Prosecution Defense Courts State Prisons Mean Years Served
Tradeoff Between Criminal Justice System Outputs Admits per Year per capita average years served tan = admits per year per capita/average years served
Capital constraint • admits per capita per year * average years served = prisoners per capita • Prisoners per capita is limited by prison capacity • If you increase admits per capita per year, then average years served decreases until prison capacity catches up
Coordinating CJS Constraint: Admits per year*Average years served = Prisoners Admits per Year 45 degrees Average Years Served
A Shifting Mix In Criminal Justice System Outputs Facts 1. spend more 2. Admit more 3. shorter time served Admits per Year per capita, AD Prison Capacity Constraint average years served, S tan = admits per year per capita/average years served

Part II • The Serious Offender • a few serious criminals account for most crimes • if free, each serious offender would commit crimes at the rate of per year • if there are N serious offenders, they would commit *N offenses per year, if free • if there are PR serious offenders in prison, then we save *PR offenses per year • the net observed offenses per year is: • OF = *N - *PR = (N -AD*S)
Serious Offenders, N Prisoners, PR Population
Serious Offenders, N Prisoners, PR Population If the Serious Offender Population grows faster than the Prison Population then crime gets worse

Social Control of Citizenry • Civil law and authority • First line of defense: moral compliance and good citizenship • Second line of defense: deterrence (the threat of punishment) • Third line of defense: detention • Martial law and authority • Fourth line of defense: National Guard and the Army

Questions About Crime • Are there Inequities by Income class? • for victims? • Are there ethnic or racial injustices? • for victims? • for offenders?

Public Goods and Private Goods • Private Goods • consumption uses them up • what you eat is not available to nourish others • Public Goods • consumption does not use them up • national defense • safe streets • educated citizenry
How Much Government Should There Be? What is the right mix of public goods and private goods? Private Goods Too Few Public Goods Optimal Mix Slope of the Production PossibilityFrontier: Marginal Cost of Public Goods ÷ Marginal Cost of Private Goods PublicGoods
The Family and Delinquency • What is the role of the family in causing or preventing delinquency? • How important is the family in considering possible causes of delinquency?

If the father is sufficiently altruistic, then the daughter’s enlightened self-interest is to prefer point A, and she can be induced to behave in a cooperative way, allowing point J that leads to point A Daughter’s Income A R J Father’s Income
Where does Criminal Justice go from here? • California • Strong economy leads to lower property crime rates • Higher imprisonment rates lead to lower rates of violent crime • National Policy • Drug treatment programs • Eisenhower Report(1999): More Prevention
Rearrest rates for CA prison Inmates rise to 67% within 3 years after release.
