Chapter 2 introduced some of the most important characteristics of Haitian peasant agriculture viewed mainly from a static perspective. In the present chapter we will widen the scope so as to adopt a dynamic view. The framework employed will be one that has been frequently and successfully used in development economics: that of circular and cumulative causation. With the aid of this framework the central thesis of the study will be presented: that the forces at work in the peasant sector generate a tendency for per capita incomes to stagnate and fall in agriculture.
