Tm. Arvanites et Ma. Asher, STATE AND COUNTRY INCARCERATION RATES - THE DIRECT AND INDIRECT EFFECTS OF RACE AND INEQUALITY, The American journal of economics and sociology, 57(2), 1998, pp. 207-221
This study examines the direct and indirect effects of race and income
inequality on imprisonment rates across states. The analysis is desig
ned to: 1) investigate whether race and income inequality are signific
antly related to imprisonment when controlling for crime, 2) assess th
e relative magnitudes of the direct and indirect effects; and 3) asses
s the relative magnitudes of race and income inequality. Crime is foun
d to be the strongest predictor of incarceration rates in five of the
six equations estimated. Income inequality is significantly related to
incarceration rates in two of the six equations. There Nas no clear e
vidence of a direct race effect. The indirect effect of race was great
er than the direct effect in four of the six equations.
