Steady Growth

  • W. A. Eltis


A Device which is much used in growth theory is the comparison of steady-state growth paths. This is the equivalent for dynamic theory of static comparisons between firms or industries in long-run equilibrium. Where a firm or an industry is in long-run static equilibrium, it is possible to specify its inputs and outputs precisely, and to use these results to compare firms or industries in differing conditions to ascertain the long-term effects of a variety of influences. Many of the conclusions of microeconomics depend on this kind of analysis, but it suffers from two major weaknesses.
