In this paper I run a regression discontinuity design analysis to document the causal effect of mayor’s wage on procurement outcomes in a large data base of public procurement contracts in Italy. To identify the wage effect, I use peculiarities of the Italian legislation where mayor’s remuneration varies at pre-determined population thresholds. My main results are as follows. First, a higher wage (i.e., my treatment) is not related with differences in aggregate measures of procurement: number of tenders, total procurement expenditure and the mean value of the contract in the municipality. Second, some of the ex-ante procurement outcomes are positively affected by mayor’s wage: the number of admitted offers and final rebates on the reserve price. Finally, a higher wage causes a significant decrease in the probability that the same firm is awarded a contract repeatedly. This paper is the first to document a direct relationship between mayor’s salary and public procurement.
