TECHNICAL CHANGE IN PRODUCTION PROCESSES OF THE SEQUENTIAL INTERINDUSTRY MODEL

Transient processes important to understanding technical change are modeled using a time-varying version of the Sequential Interindustry Model, SIM. A simple process of technical change is explored, where a new production technique replaces an old one for one of an industry's production processes. Using several measures internal and external to the industry the model can help in understanding the complex processes of technical change, point to difficulties in their analysis, and suggest guidance to further examinations. An earlier version of this paper was presented at the Eighth International Conference on Input-Output Techniques, Sapporo, Japan, July 1986.     

Interindustry analysis for regional growth and development: The dynamics of manpower issues

Simulations of two scenarios to illustrate processes of regional interindustrial growth and development suggest the dynamics of manpower issues. Using the core of the Sequential Interindustry Model, SIM, the dynamics by which interindustry production supplies continuing final markets is presented and the resulting industry production chronologies illustrated. The latter are transformed into employment chronologies from which labor requirements are computed as distributions of potential jobs by job duration and job starts.Adjustments in potential jobs to represent the dynamic linkages between manpower demand and supply in fluctuating labor markets are discussed as an extension of adaptive behavior in SIM. An encompassing impact dynamics framework for manpower assessment is suggested, including examination of management options of both demand and supply for timely impact mitigation.
