Early work concentrated on adapting the statistical decision-theoretic approach to deal with control problems of discrete-time dynamic systems with imprecisely known characteristics, or operating in imprecisely known environments. My monograph, Optimization of Stochastic Systems, provides a framework for treating these systems as parameter of large-scale dynamic systems or systems composed of several interdependent subsystems with central or independent decision agents, so-called decentralised dynamic systems. From these systems, my interests eventually settled on dynamic problems associated with open economy macroeconomics and problems of policy effectiveness studies in systems of interdependent economies.
I have attempted to conduct comparative dynamic analysis in open economy macroeconomics and to introduce to the economic profession some techniques and concepts from system theory that I found useful. My 1976 book provides a set of tools and concepts to conduct comparative dynamic analysis of economic models. My 1981 book mostly analyses adjustment processes in two and three country models of the world under floating exchange rate regimes.
My 1983 lecture notes set out a procedure that has been developed in system theory for systematic construction of state space or Markovian models from vector-valued time series data.
