Rent-seeking, rent-defending, and rent dissipation

In the preceding analyses of rent-defending, the Posner model yielded welfare losses in excess of the combined areas of the Tullock rectangle and the Harberger triangle in only one instance. Furthermore, this particular circumstance necessitated voluntary participation in a game with a negative expected value.13 For the Tullock-Rogerson model, the explicit addition of rent-defenders had no impact on aggregate dissipation.
