The purpose of this paper is to provide a coherent framework to explain the unusual phenomena of employment, real wage, and profit share observed in industrialised economies since the 1980s, in relation to the speed of demand saturation. To this end, we use a multisectoral model including capital goods and the stochastic emergence of new products. We show that faster demand saturation tends to accelerate the growth of employment but decelerate the growth of the real wage. Furthermore, we show that faster demand saturation tends to increase the profit share and the share eventually converges irrespective of the difference in the speed of demand saturation. Finally, it is argued that our model has a critical implication for the non-accelerating inflation rate of unemployment (NAIRU).
