Economics of Crime

Victoria Vernon, Ph.D.Empire State College

Examples of economic questions in this course:

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

• 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?

• Legalize drugs?

• Death penalty?

Outline for Today

• What is Economics?• What is crime?• Rational criminals• How much crime is there? • What is the economic impact of crime?

• Graphs

• Correlation vs causal link

What is Economics?Economics studies • how people make CHOICES• allocation of scarce resources among alternative

uses • how do we allocate SCARCE RESOURCES to

satisfy the most pressing of our UNLIMITED WANTS?

The science of decision-making

INDIVIDUAL’S RESOURCES– Money– Time– Effort

SOCIETY’S RESOURCES– Land– Labor– Capital– Entrepreneurial abilities

How do we make choices? (Economics Philosophy)

• People are SELFISH– Maximize our own joy, happiness– UTILITY=

subjective measure of joy, pleasure, happiness, satisfaction from consuming goods/services

• People are RATIONAL– compare COSTS and BENEFITS of alternatives,Examples of decisions:

Buying a cup of coffeeGoing to collegeCommitting a crime

• People respond to incentives• All choices involve OPPORTUNITY COSTS

– the next best alternative foregone

Rational decision example: Go to college?

• Benefits:–higher future income: $100,000– lower insurance rates: $5,000–better health: $15,000–other ?

Total benefits : $120,000

Benefits> Costs

• Costs:– tuition, books: $40,000– lost income: $60,000

Total cost: $100,000

Rational decision example: Steel a car?

• Benefits (expected):

Benefits > Costs ?

• Costs (expected):

choice

Work and no violence

Work andbrawl in bars

expect $24,000/yr

Apprehended: $22,000lose 1 month in court andjail

0.9 Not apprehended$24,000

Expected income: 0.1*$22,000 + 0.9*$24,000 = $23,800Expected cost: $200Compare benefit and cost.

Rational choice: brawl in bars?

Loss of resources spent on defense

What is the nature of crime?

• Crime is income redistribution

• Crime is a dead-weight loss for society– Loss of resources spent on defense

• protection of homes, cars, bicycles

– These resources could be spent on goods and services

– Victim has less incentive to be productive– The impact on social welfare

• Unambiguously bad

• Criminal does not take into account impact on society

Total Costs of Crime for Society• Goods and services (tangible)

– Value of property destroyed– Time and resources spent by criminal– Medical /health services for victims– Police and fire services– Cost of jail time for taxpayers– Loss of productivity and wages by victim • Quality of life (psychic) by victim, family, friends• Loss to bystanders, third parties and society (negative

externalities)– Cost of crime prevention activities: locks, guards,

alarms, insurance, etc– Spending on criminal justice system– Taxes, property values, migration from neighborhoods– Moral climate of society
