ABSTRACT
Development economics is a reference to the field and its concern or subject matter is economic development. The social, political and ecological impacts of economic growth may undermine sustained prosperity even if it is well distributed. Theorizing involves logically identifying the causal relationship between key economic variables like prices and quantities while abstracting from others not likely to have a bearing on the association. Economic models are utilized to theorize and add to the body of secure knowledge on a particular theory within a particular field. Mainstream economists could find a defense against these criticisms should they be willing to engage. Structural change is measurable and the most frequent reference to structural change in development economics pertains to the alteration in the relative size of the various sectors of the economy over time. Structural change or transformation could also result in institutional change. Pressure points can emerge from structural change that requires institutional change.
