Numerical Models of Economic Development by A. Qayum. Rotterdam University Press, 1966.

From the author’s preface, “this is a collection of some of my published and unpublished articles containing simple models relating to problems of economic development of underdeveloped countries. A characteristic common to all the models discussed here is that they lead to numbers or to figures corresponding to numbers”. This is an indirect way of saying that the author has taken a quantitative approach to problems of development as opposed to the usual verbal —empirical approach. In that the author has the reviewer’s whole-hearted support.
