Mongi Azabou, Timur Kuran, and Mustapha Nabli
Over the past three decades, the share of Tunisia's output of fruits
and vegetables passing through the capital's wholesale market has declined
sharply. One reason is that, following the formation of a porters' cooperative,
the cost of portage services and, hence, that of using the market has skyrocketed.
In advancing this argument, the paper explores how the cooperative has
managed to maintain a monopoly over portage services despite widespread
dissatisfaction with its performance. In addition, it offers some thoughts
on the distributional and efficiency implications of various changes engendered
by the cooperative in the market's mode of operation.
