Market Analysis concepts

market supply marginal cost of production: the additional cost of

one more unit cost of production equals the sum of marginal costs revenue = price * quantity sold

market demand price some consumers are willing to pay expenditure = price * quantity bought consumer surplus: a measure of welfare for those

consumers willing to pay above the market price

18

Market Analysis Concepts

supply and demand determines the market price

the marginal cost of production = the marginal value of consumers

the quantity demanded equals the quantity supplied

profit = revenue - cost of productionprofit, or producer’s surplus, is a welfare measure

total welfare benefit = consumer’s surplus + producer’s surplus

An individual would weigh the benefits against the costs

If the benefit/cost ratio exceeds one smoke drink

Could impose costs on others driving under the influence second hand smoke

Protection of Minors blandishments of advertising influence of peers

32

Health

Treat substance abuseNeed to identify the abusers many citizens are not covered under health plans

Difficult to cure addicts

33

Fiscal Policy

Use excise taxes, a tax per unit, to control demand

tax per pack of cigarettes

tax per bottle of gin

Policy moderates rather than eliminates uselacks the moral suasion of a law prohibiting use

34

Law Enforcement Control demand?

hard to keep tabs on numerous users

loss of respect for the law people like to party

Control supply?at home search and destroy policies have a low success

rate

abroad interdiction of supply has low success rate we export our enforcement problem to:

producing countries, e.g. Bolivia, Peru, Colombia

Trans-shipment countries, e.g. Mexico35

The Economics of Crime Control

Objective: minimize the sum of damages to victims and expenditures on the criminal justice system

Damages to victims = loss rate* offenses, or in symbols r*of

Expenditures on the criminal justice system, abbreviated CJS, for law enforcement, trials (district attorneys, public defenders, judges) and operating jails and prisons

The Graphics of Total Cost, TC

TC = r*OF + E

Optimal Expenditure

Economic Paradigm1. Choose objective

e. g. minimize sum ofdamages to victims plus expenditures, E, on CJS

2. Describe states of the world (options for choice)

Total cost curve (E)

3. Choose the best option

What Have We LearnedEven if crime is controllable, the optimal level of crime ( and damages to victims) is not zero

There comes a point where spending more on crime control, i.e. the CJS, costs more than is saved by reducing damages to victims, and this is where total costs start to rise above their minimum

What Did We Learn From Prohibition, 1919-1933?

The argument was: misuse or abuse of alcohol can have bad effects

Drunken husbands beat their wives

Drunken mothers mistreat their children

But the majority of people did not want to give up alcohol

Following the passage of the Volstead Act in 1919, we witnessed rum-runners, speakeasies, people making beer and bathtub gin

Outline and Issues 9/27/2011

Course logistics: gauchospace

Criminal Justice System (CJS) & economic paradigm: where do the values (prices) come from to evaluate the states (outcomes) of the CJS?

How much crime is there? How do we know?

Crime has two effects: Redistribution of welfare from the victim to the

perpetrator Opportunity cost or waste of resources for defense

How is Crime Measured

Victimization Surveys of Households U S Dept of Justice, Bureau of Justice Statistics,

Criminal Victimization

Citizen (Victim) Reports to Police U S Dept of Justice, FBI, Uniform Crime Reports

A Theme for this Course

Criminal Justice System is in crisis. Courts told former Governor Schwarzenegger to find

housing for prisoners or release them early City and County jails are overflowing and a revolving

door policy is in effect. Repeat offenders clog the system

Not enough judges and prosecutors

It Has Not Always Been This Way

The Criminal Justice System had been relatively stable in the decade after World War II

What happened? That is the story of this course.

We will review the history of criminal justice in the 60-plus years since WW II.

We will suggest policies that will help turn things around now. In brief, what is needed is triage, i.e. to use scarce resources that will improve public safety the most.

Questions about crimeQuestions about crime

Is crime a real problem or a media induced problem?

Is crime an economic problem?

Are we getting our money’s worth for the dollars we spend on police, jails, and prisons?

Questions about the Operation of CJS

If crime is going down, why are we devoting more resources to its control?

If drug offenders are mostly non-violent, why do we send them to state prison instead of rehabilitation?

Bad effects from taking crimes

Bad effects from taking crimes

Victim has less incentive to be productive

Victim has more incentive to spend time and money on defense

Analogous to war: guns vs. butter

What is society going to produce? defense against crime? or goods and services?

Questions About CrimeDoes the Expected Severity of Punishment Deter Crime?

expected severity = probability of punishment * severity of punishment

e.g. in LA County: 0.005*death penalty

Why Do We Keep Building Prisons at Great Expense to Warehouse Convicts?

Doesn’t deterrence work?

Do we have to rely on detention?

Controversy About the Death Penalty

Death penalty is the most severe sentence. Does it deter crime?

Opponents of the death penalty say no.Their evidence? Critiques of studies that indicate the death penalty is a deterrent.

Why are so few murderers who receive the death sentence executed in California? Death sentence appeases the proponents. Few executions appeases the opponents.

Executions in the US 1930-2007

Peak to Peak: About 65 years

Bureau of Justice Statistics

Peak to Peak: 50 years

Policy Impact of Opponents to the Death

Penalty As an instrument for crime control, deterrence has been a casualty of the argument about the death penalty. The argument: if the death penalty does not

deter murderers, then deterrence must not work as a control.

As a consequence, society relies more and more on detention for crime control. Society builds more and more prisons.

U.S.

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.
