Context for Deterrence and Rational Choice
Deterrence Theory
Rational Choice Theory
Matseuda, Kreager, & Huzinga (2006)
Went a little far--more structural, more deterministic theories--often called "oversocialized" perspectives.
Criticism of the classical school lead to rejection of rational actor
Criminology dominated by subcultural theories well into 1970s.
Went a little far--more structural, more deterministic theories--often called "oversocialized" perspectives.
These include differential association, differential opportunity, strain theory, etc.
Subcultural theories usually focus on normative conflict or difference: Crime occurs because people are members of subcultures that reject conventional norms and have pro-crime norms.

Move toward rehabilitative model in 1960s and onward was not associated with dropping crime
People became pessimistic--"there's nothing to be done"--so just lock folks up and throw away key

James Q. Wilson was influential political scientist and policy writer. Focused on crime a lot.
Thinking About Crime introduced idea of incapacitation as mechanism for crime reduction in places with higher penalties.
We'll talk about incapacitation more later.
Also wrote the original Broken Windows article with George Kelling and was pro War on Drugs on moral grounds.

Rather than focus on the intervening work first, we begin at deterrence.

Deterrence is still fundamental basis for most crime policy. If penalties go up, crime should go down.
Deterrence is framed now in terms of rational choice but has long been basis from criminal legal policy
As seen in week 1, deterrence goes back to Beccaria and Bentham.
It entered US CJ policy at foundation of nation and hasn't gone anywhere. More or less same into Europe.

First well-known general utility model of crime.

Swinging pendulum back to actors as being decision-makers and away from deterministic cultural theories
People do not pick optimal choice every time but do on average
Key is that people respond to incentives
People's perceived rewards are idiosyncratic and taste-based; mainly just know that on average people want more, whatever it is

If rational choice can explain criminality well, it can likely explain more rational things as well
Deterrence is simply the idea that punishment can impact crime.

Weaker assumptions than classical school
Rational actor assumptions:
If you look at large groups together, on average they behave rationally
Deterrence is simply the idea that punishment can impact crime.
Weaker assumptions than classical school
Rational actor assumptions:
In aggregate, individuals act rationally
At margin, individuals act rationally
If you look at large groups together, on average they behave rationally
People may not act perfectly rationally, but they do respond
If punishment increases, people will commit less crime; if gains increase, more.

Absolute Deterrence
This is question of whether any penalty at all has an effect on a behavior.
Absolute Deterrence
Marginal Deterrence
This is question of whether any penalty at all has an effect on a behavior.
This is if increasing or decreasing penalties increases or decreases behavior.
Certainty
Tittle's Shell of Illusion: Those never committing a crime--and thus never getting away with it--overestimate sanction risk.
This is related to the illusion most people have that certain types of law violation are incredibly rare; since at least Rome philosophers have stated that if people knew how often laws were broken, they too would break them.

Subjective usually involves asking people "how bad would it be to be arrested / incarcerated"

Not often used
Time discounting in economics--a loss or gain in the future is worth less than one now
Not real relevant in US system due to everything being slow
The slowness may actually be a severity component too; people know they'll spend a lot of time even waiting for a hearing or trial
Does the threat of punishment deter people from crime?
Does the threat of punishment deter people from crime?
Research Approaches
Does being punished deter people from committing more crime?
Specific deterrence is about keeping people from reoffending
If they were punished once, they will realize they don't want that to happen again

If they were punished once, they will realize they don't want that to happen again
Specific deterrence can be hard to research--punishment often does more than just punish.
Not really ethical to experimentally vary real punishments; can try in experiments
Deterrence focuses on the sanctioning.
Rational choice is a general theory of behavior--not limited to crime.

Full rational choice models recognize variation in gains.
Article found better support for rational response to rewards than to formal deterrence
Later work often shows similar--may be due to low risk of apprehension

Rational choice models typically take a formal mathematical form.
E(U)=(1−p)U(y)+pU(y−F) "Expected utility E(U) is function of the value of crime U(y), the likelihood of being caught p, and the penalty if caught F"
This is conventional economic utility model
Don't estimate exact values, but rather takes advantage of basic properties
All else equal, reducing reward / increasing cost reduces value and thus likelihood of crime.

Mixed methods work revealing participation in gang fights as rational behavior
Gang leader decides whether or not to join a fight
If he decides not to, likely he will likely suffer moderate status loss with gang
If he does join fight, small chance he will need to shoot someone and end up in jail -- large cost
Because likelihood of jail is small, he'll probably join fight--it is rational to do so
Rational choice hypothesis: Perceived cost/benefit impacts future crime
That is, crime occurs when reward weighted by likelihood of getting it is higher than sanction risk weighted by likelihood.

Research Questions:
How are perceived risks formed?
How do perceived risks and rewards influence crime?

Data: Denver Youth Survey
That is, crime occurs when reward weighted by likelihood of getting it is higher than sanction risk weighted by likelihood.
1526 youth surveyed over 10 waves--only first five have rat choice questions
Very detailed questions on involvement in crime, perceptions of it, background
Deterrence: Perceptions should be rooted in reality
Perceived risks come from real experiences
Those who have never committed a crime think they're likely to be caught
When they get away with it (or get punished), they update perceptions--this is a Bayesian updating model

DYS has actual arrests and committed crimes for respondents
Know number of unsanctioned offenses
Also know crimes of their peers--we assume peers getting away with it (or being sanctioned) gives info
Baseline risk is perceived risk of arrest at last survey
New info is unsanctioned offenses, arrests, and delinquency of peers since last survey.
Updated risk is current survey.
The model is somewhat more complicated: Preceding neighborhood and individual characteristics also predict all three.
Find support for shell of illusion: High risk perceived by those not comitting
Then risk increases with experienced certainty. Looks basically same for violence.
People who never committed a crime perceive risk of sanctions similarly to those who did and were always caught
Rewards
Focus here on psychic gains, both direct (excitement) and from status (being seen as cool)

Cost
Focus here on psychic gains, both direct (excitement) and from status (being seen as cool)
Main analyzed cost here is arrest but they also investigated trouble with parents, risk of ending up in jail or reform school
Similar but weaker effects compared to arrest

Measured as a percentage in 10 point increments
5 point scale
The cost or benefit ends up as a variable equal to the certainty times the value.

Also address reality that crime can't be committed without the opportunity to do so, so asks if they had the opportunity to commit crimes
Original participation in crime predicts perceived risks and gains as well as future crime
Future crime predicted by these perceived risks and gains
Small deterrent effect
Evidence for modest deterrent effect, but relationship much stronger with rewards
Youth more sensitive to the gains than the costs
Small deterrent effect
US already has high arrest and imprisonment rates
Evidence for modest deterrent effect, but relationship much stronger with rewards
Youth more sensitive to the gains than the costs
Not practical to increase risk sufficiently to deter these crimes

US already has high arrest and imprisonment rates
Some level of arrest and incarceration essential

Can't punish our way out of this. Better to address, in particular, psychic gains of crime.
