The following is a sample of some of the criminological theories that have been used to explain why people commit crime.
Deterrence Theory by Beccaria
Deterrence theory argues that a particular behavior is inhibited or deterred in direct proportion to the perceived probability and severity of punishment expected for the behavior.
Rational Choice Theory by Becker
Rational choice theorists address the perceived probabilities and magnitudes of both rewards and punishment. Deterrence theory omits this reward component. Expected utility principle- people make rational decisions based on the extent to which they expect the choice to maximize their profits or benefits and minimize their costs or losses.
