I think of myself as an applied econometrician with a special interest in microeconomic topics. My early research involved empirical implementation of translog production and cost functions. Subsequent theoretical research focussed on relationships among the concepts of functional separability, substitution elasticities, and consistent aggregation.
This mix of economic theory and empirical implementations then led me to examine alternative criteria for testing hypothesis in multiple equation systems, and also extended to a consideration of problems in consistently specifying vector autoregressive processes in singular equation systems. In the last decade much of my empirical research has involved modelling the special relationship between energy and capital, and examining implications of the Organisation of Petroleum Export Countries energy price increases on investment, capacity output and productivity. The initial framework employed a static optimisation framework but by the late 1970s I was involved in estimation of dynamic factor demand models.
Currently my research is a mix of analyses of energy-productivity interactions, the integration of hedonic price analyses with the theory of cost and production, the measurement of consumers’ evaluations of technical design innovations in the Swedish and United States automobile markets, and an evaluation of productivity performance in the 200 United States electric power industries.
