Technological Progress, Downsizing and Unemployment

This paper presents a model where the form of innovations is endogenous. It is shown that with labour market imperfections, which raise the wage above the shadow price of labour, firms over-invest in innovations cutting labour costs and under-invest in increasing quality. As a result, the market outcome features lower long run growth, higher unemployment and lower welfare than the social optimum. It is further shown that a firm's incentives to cut labour costs are increased as wages rise and as the firm declines. Finally, a rise in competition increases incentives to downsize for firms with below average quality performance.
