The empirical studies on capital punishments deterrence effect are mixed. Meta-analysis suggests that the empirical evidence provided to date is too fragile and, therefore, can serve as a guide to policy decisions.Despite employing econometric analysis for over forty years, the deterrent impact of capital punishment remains uncertain.
