6 5 Outline w The Meth Epidemic w Crime in California

7 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

8 7 Brain scan study At UCLA Effect on The body

11 10 50 % of children In Oregon are there Because of meth- Addicted parents

13 12 Crime in California w Causality and Control w Corrections: Dynamics and Economics w Correctional Bureaucracy

14 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”

17 16 What are the facts? w Expenditures per capita on the CA criminal justice system

18 17

19 18

20 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

21 20 Trends In Crime in California Source: Crime and Delinquency in California, 2002 http://caag.state.ca.us/ Social Welfare Lecture (#1 LP)

22 21 Crime in California 2005

23 22 Crime in California 2005

24 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 24

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

27 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

28 27 Crime Generation Crime Control Offense Rate Per Capita Expected Cost of Punishment Schematic of the Criminal Justice System; Jobs and Crime Causes ?:Economic Conditions (detention, deterrence) Expenditures Weak Link

31 30 Note: w The misery index bottoms out in 1998 and the crime rate bottoms out in 1999 w There is visual evidence that there may be a connection

32 Jobs and Crime

33 32 2002 1952 1980 1954 Jobs and Crime Lec #2 LP

34 Jobs and Crime

35 34 What are the facts? w Control variables Imprisonment as a measure of detention and deterrence

36 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”

37 36

38 37 The number of prisoners per capita is leveling off w Is this why the crime rate is turning up?

39 38

40 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 40

42 41 What is Affecting Crime Rates? w Economic Conditions? w Imprisonment Rates? w Both?

43 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)

46 45 California Forecasts w Using the Fitted Model to Forecast

48 47 California Department of Corrections: Institutional Population http://www.cdc.state.ca.us/reports/populatn.htm

49 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

54 53

55 54 California Department of Corrections: Total Felon Admissions http://www.cdc.state.ca.us/reports/populatn.htm

56 55

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

68 Total Expenditure per capita on CJScapita on CJS Expenditures per capita, Corrections Expenditures per capita, Enforcement Admits per capita Average Years Served Production Function

70 Total Expenditure per capita on CJScapita on CJS Expenditures per capita, Corrections Expenditures per capita, Enforcement Admits per capita Average Years Served Production Function

71 70 Admits per Year per capita, AD average years served, S A Shifting Mix In Criminal Justice System Outputs  tan  = admits per year per capita/average years served  Facts 1. spend more 2. Admit more 3. shorter time served   Prison Capacity Constraint

73 72 Crime in California w Causality and Control wCwCorrections: Dynamics and Economics wCwCorrectional Bureaucracy

74 73 California Corrections Bureaucracy w Prisoner and Parole Populations Stocks w Felon New Admissions From Court Inflow to Prison w Prisoners Released to Parole Outflow from Prison/Inflow to Parole w Parole Violators Outflow from Parole w Discharges from Parole and Deaths Outflow from Parole

75 California Department of Corrections 1996 Prisoners 145,565 Parolees 100,935 Felon New Admits 46,487 Releases to Parole 111,532 Discharged and Died 27,691 57,984 Parole Violators Returned to Custody Parole Violators With a New Term 17,525 Parolees At Large 18,034 Discharged and Died 3,984 Absconded 29,376
