Citizens' demand for permits and Kwerel's incentive compatible mechanism for pollution control

An interesting feature of pollution permit markets is that citizens may purchase permits to directly lower the levels of pollution. Kwerel's mechanism (Review of Economic Studies similar to 1977) is not incentive compatible when citizens demand permits. We show that a modification of Kwerel's mechainism, the minimum-price mechanism, is incentive compatible when citizens demand permits, even in the case where there is uncertainty about the damages from pollution.
