Technical Change and Employment under Imperfect Competition with Perfect and Imperfect Information

Abstract: We consider the implications of process innovation for the aggregate level of employment of assuming that not all firms adopt new technologies simultaneously and that non-innovators adopt (temporarily) disequilibrium strategies (due to imperfect information about the introduction of the new technology). Two alternative scenarios are explored. In one, consumers' demands arise from symmetric homothetic preferences, and in the other from asymmetric (Hotelling-type) preferences. We find that there may be a reduction in employment in the transition to the new equilibrium under both types of preferences even if there is no decrease (or an increase) in the new (long-run) equilibrium level of employment. The conditions under which this will occur are however different for the alternative preference structures. Further, the latter are shown to have different implications for the equilibrium effects of process innovation.
