ABSTRACT
There are, broadly speaking, two types of development theory. The first is concerned with explaining the genesis of progress, or the lack of i t : and the subsequent course of growth. The second is concerned with planning growth, hence with breaking the bottlenecks to a forced, more or less state-directed, process of growth. It is the second kind of theory which interests us directly: this is also the kind of theory in which many economists move with greater ease. It is forward-looking, and the models produced can be more abstract, and any figures more illustrative. It can and does rapidly degenerate into total irrelevancy.
