My research is largely concerned with understanding why countries and regions differ in terms of their economic and productivity growth rates. My early research was on the theoretical elaboration and statistical testing of the "Verdoorn law". This empirical relationship between industrial productivity and manufacturing growth was first given prominence by the late Lord Kaldor. This relationship provided evidence of the importance of increasing returns to scale in economic growth. Subsequent research concentrated on the role of the balance of payments in constraining the rate of economic growth. I am presently engaged in work that is essentially a critique of the neoclassical approach to measuring the rate of technical change. It involves an examination of the foundations of the aggregate production function, including issues raised in the Capital Theory Capital Controversies, aggregation problems and, in particular, the insurmountable problems posed by the use of value data and the presence of an accounting identity for the estimations of putative aggregate production functions. My research is currently changing with the recent establishment of the Centre for Economic and Public Policy, of which I am the Director.
