This paper studies the male homicide rate and its relation to economic variables in the states of Minas Gerais, São Paulo e Rio de Janeiro between 1981 and 1997. The novelty of our approach is the construction of homicide rates specific for each age between 15 and 40 years old. The economic variables' coefficients are significant1y different from zero for the population between 15 and 19 years old. As expected, an increase in real wage and a decrease in inequality reduce the rate of homicide. Surprisingly, a decrease in the unemployment rate seems to increase the rate ofhomicide. Most coefficients, however, converge to zero as a generation gets older, becoming non-significant for the population aged 20 years old or more. We also identify an inertia component in the homicide rate: generations with higher homicide rates when young also tend to have higher homicide rates over the remain of their life cycle. Therefore, if economic variables induce a high rate of homicide among young people in a certain year, this high rate tend to persist over the generation life cycle independent1y of the economy later behavior. Regressions are performed using a reformulation of the standard Logit model that incorporates a lagged dependent variable.
