N.H. Stern on substance and method in development economics

Stern's observations on some major topics in development economics are examined, notably his interpretation of the hypothesis of the vicious circle of poverty, as well as his observations on the extent, movement and measurement of international income differences, the implications of central planning, and the effects of development aid. Issues of both substance and method are examined. The inadequacies of some leading ideas of development economics, defended by Stern, are considered. Significant instances of inappropriate aggregation and quantification are noted, as well as some results of the treatment as parameters of factors which are regarded appropriately as variables. Problems of assessing evidence, including assessment of the effects of policies, are also discussed.
