This paper computes a measure of rent-seeking based on costs of tenure
. Within a political tenure type model, a new incumbency variable is i
ntroduced and a variant to existing datasets is presented. Consistent
ML rent-seeking estimates are computed for our sample of OECD democrac
ies. The statistical advances in limited dependent variable models in
particular, the decomposition of the Tobit estimates enabled us to com
pute rent-seeking estimates as costs of tenure the Tobit partial deriv
atives and to compute the impact of explanatory variables on the proba
bility of being above the limit which we interpret as the probability
of tenure.
