Technological Progress and Sectoral Shares

Australian Economic Papers, 2018, vol. 57, issue 2, 142-153

Abstract: This paper studies the effect of differences in the rate of technological progress between sectors on their relative sizes. There are two sectors: a stagnant sector, where productivity does not change over time, and a progressive sector, where costs decrease over time. We consider a conjectural variation approach which encompasses perfect competition, oligopoly and monopoly. The evolution of the relative shares of the stagnant and progressive sectors over time depends on the type of competition, cost levels and the price elasticity of demand. The relationship with the cost disease literature is discussed.
