Author: Theory of Technical Change and Economic Invariance: Applications of Lie Groups, 1981. Co-author: Research and Productivity.
My early work in economics concentrated on the theory of economic growth. My 1968 book, Theory of Economic Growth, presented a comprehensive analysis of modern growth theories, including classical, Schumpeterian, HarrodDomar, neoclassical theories, and contemporary optimal growth theory. Production function analysis and the estimation of technical progress followed as a result of work with John Kendrick in the 1960s.
A model of biassed technical progress was first formulated and applied to United States data in the late 1960s. In the early 1970s, my interest shifted to the formulation of modern production theory incorporating technical progress functions. This research endeavour led to the study of invariance problems in economics and culminated in the 1981 book, Theory of Technical Change.
Subjects covered in
the book include (1) analysis of technical change and returns to scale, (2) selfduality of preference and technologies, (3) general recoverability problem of optimal dynamic behaviour, (4) economic conservation laws and (5) invariant index number problems.
Some recent contributions include the application of Noether’s invariance principle to uncover some hidden dynamic symmetries and conservation laws, the study (with P. Samuelson) of the integrability conditions in the general case of demand for money and goods, and the development of an endogenous theory of technical progress presented in Research and Productivity (with G. Suzawa). Current research interest is in the application of differential games to areas like the Schumpeterian hypothesis, market structure, and international rivalry in R&D and international trade.
