A search model for Joint Implementation

The aim of this paper is to present a search mode l in the field of environmental economics, where so-called clean and dirty producers enter the trading market, both looking for a partner with whom to exchange the goods they are endowed with. The model derived in this paper is rather simple. Nevertheless, it is able to produce a series of interesting results and useful insights , and is conveniently used here as a framework to explain the functioning of Joint Implementation programs for polluting emissions’ reduction.
