Development Economics is the proposition on which development economics was built was that poor countries were intrinsically different from rich ones and so needed their own set of economic models. Some development economists argued, for instance, that the self-interested, rational individual did not exist in traditional tribal societies. They claimed that because many poor countries had large agricultural populations and were often dependent on a few commodity exports for foreign exchange earnings, economic policies that suited rich countries would not work for them. However, the sequencing of these new policies seemed to make a big difference to how well they worked.
