Abstract:
The condition that characterizes the optimal size of a tax-collection agency is der ived and then given a simple interpretation in terms of excess burden This paper clarifies an earlier finding of A. Sandmo (1981) which s uggests that the optimal degree of enforcement is higher than a simpl e cost-benefit calculation would indicate. The appropriate condition is that, at the margin, the resource cost of increasing enforcement s hould equal the saving of excess burden due to the decline in exposur e to risk. The increased revenue gained from stricter enforcement doe s not enter the expression because it merely represents a transfer am ong the economy's identical agents.
