Ill-Defined Institutions and the Production of Inefficacity : A Case Study of Unexpected Perverse Effects Causation in Haitian Traffic Regulation Rules

It is well documented that institutions can produce effectiveness by reducing uncertainty, transaction costs, and allow good anticipations, among other effects. Other researches show that not all institutions matter. In this article, based on a case study in Haitian traffic regulation, we show that ill-defined institutions produce incredible inefficacity, particularly unexpected perverse effect.

The basic idea is that it is easier for DGT to manage ground transportation institutionally than technically
