6 Front Line: The Meth Epidemic w http://www.pbs.org Assignment for class http://www.pbs.org w 1.5 million addicts in the US Worldwide more addicts than for horse and coke, combined w Different than heroin and cocaine No natural supply Synthetic 9 factories in the world manufacture pseudoephedrin w Could focus on Supply Limit availability of pseudoephedrin Roadblock: pharmaceutical lobby

1952-2004
15
14 Use the California Experience w Crime rates Have Fallen. Why Haven’t Imprisonment rates? w Apply the conceptual tools developed prior to the midterm Criminal justice system schematic crime control technology
16
Crime Generation Crime Control Offense Rate Per Capita Expected Cost of Punishment Schematic of the Criminal Justice System: Coordinating CJS Causes ?!! (detention, deterrence) Expenditures Weak Link “The Driving Force”

19 What are the facts? w Expenditures per capita on the CA criminal justice system Expenditures per capita in real $ are rising steadily The big ticket items are enforcement and corrections w Offenses per capita

23 What are the facts? w Offense rates per capita rose rapidly until 1980 w Leveled off in the 1980’s w Declined in the nineties w Are rising again
25

26
25 Can we identify the causes? w The factors that cause crime might have been getting better in the latter 90’s

26 Crime Generation Crime Control Offense Rate Per Capita Expected Cost of Punishment Schematic of the Criminal Justice System; Death Penalty Causes ? (detention, deterrence) Expenditures Weak Link Variable, up & down Steady increase

37 The number of prisoners per capita is leveling off w Is this why the crime rate is turning up?
39

39 Note w When prisoners per capita was flat, offenses per capita was growing w When prisoners per capita started growing, offenses per capita leveled off and then declined

41 What is Affecting Crime Rates? w Economic Conditions? w Imprisonment Rates? w Both?

42 Model Schematic Crime Generation: California Index Offenses Per Capita Causality: California Misery Index Crime Control: California Prisoners Per Capita
44
43 CA Crime Index Per Capita (t) = 0.039 + 0.00034*Misery Index (t) – 3.701*Prisoners Per Capita (t) + e(t) where e(t) = 0.954*e(t-1)
45
44 Ln CA Crime Index Per Capita (t) = -5.25 + 0.17*ln Misery Index (t) -0.22 ln Prisoners Per capita (t) +e(t) where e(t) = 0.93 e(t-1)

48 Crime in California w Causality and Control wCwCorrections: Dynamics and Economics
50
49 Prison Dynamics and Economics w Admissions * mean years served = prisoners
51
50 Relationships Between Stocks and Flows: Coordinating CJS w In equilibrium: Inflow = Outflow w The outflow is proportional to the stock Outflow = k * Stock constant of proportionality, k, equals one divided by mean time served –Admits * mean years served = stock of prisoners
52
51 The Stock of Prisoners InflowOutflow Stock of Prisoners New Admissions from Court Released to Parole Coordinating CJS
53
52 45 degrees Constraint: Admits per year*Average years served = Prisoners Average Years Served Admits per Year Coordinating CJS

57
56 Prison Realities w We can not build prisons fast enough to increase capacity soon enough w The public wants more convicts sent to prison w But prisons are full w So, what happens?
58
57 Consequence w Release violent offenders w Innocent children are kidnapped, raped and murdered: example-Polly Klass
59
58 Consequence w Polly’s father campaigns for three strikes law
60
59 Consequence w More convicts are sent to prison
61
60
62
61 Capital constraint: Coordinating CJS w admits per capita per year * average years served = prisoners per capita w Prisoners per capita is limited by prison capacity w If you increase admits per capita per year, then average years served decreases until prison capacity catches up
63
62 Prison Dynamics and Economics wAwAdmissions * mean years served = prisoners Dynamics wPwProduction Possibility Frontier Economics
64
63 Abstraction (Model) of the Criminal Justice System Enforcement Prosecution Defense Courts State Prisons New Admits Mean Years Served
65
64 Admits per Year per capita average years served Tradeoff Between Criminal Justice System Outputs tan = admits per year per capita/average years served
66
65 Resource constraint w expenditure per capita on CJS = expenditure per capita on enforcement, prosecution, and adjudication plus expenditure per capita on corrections w admits per year per capita depends on expenditures per capita on enforcement, etc. w average years served depends on expenditures per capita on corrections
67
Admits per Capita Expenditures per capita on Enforcement Average Years Served Expenditures per capita on Corrections production function production function Expenditures per capita on Corrections Expenditures per capita on Enforcement Total Expenditures per capita on Criminal Justice System
