According to deterrence theory, criminals are no different from law-abiding people. Criminals [economist Paul H. Rubin writes] "rationally maximize their own self-interest (utility) subject to constraints (prices, incomes) that they face in the marketplace and elsewhere." Individuals make their decisions based on the net costs and benefits of each alternative. Thus, deterrence theory provides a basis for analyzing how capital punishment should influence murder rates. Over the years, several studies have demonstrated a link between executions and decreases in murder rates. In fact, studies done in recent years, using sophisticated panel data methods, consistently demonstrate a strong link between executions and reduced murder incidents.
