6 Llad Phillips6 Conclusions Causal conditions continue to get worse Causal conditions continue to get worse As a consequence we have to spend more real dollars per person to keep crime levels from rising As a consequence we have to spend more real dollars per person to keep crime levels from rising Crime acts like a tax Crime acts like a tax  Californians spend $450 (1992$) per person on criminal justice to keep things from getting worse

7 Llad Phillips7 Question What happened around 1980 to differentiate the 50’s, 60’s, and 70’s from the 80’s and 90’s? 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?

12 Llad Phillips12 Admits per Year per capita average years served Tradeoff Between Criminal Justice System Outputs  tan  = admits per year per capita/average years served

13 Llad Phillips13 Capital constraint admits per capita per year * average years served = prisoners per capita admits per capita per year * average years served = prisoners per capita Prisoners per capita is limited by prison capacity 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 If you increase admits per capita per year, then average years served decreases until prison capacity catches up

18 Llad Phillips18 Part II The Serious Offender 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)

19 Llad Phillips19 Population Serious Offenders, N Prisoners, PR

20 Llad Phillips20 Population Serious Offenders, N Prisoners, PR If the Serious Offender Population grows faster than the Prison Population then crime gets worse
