For example, if 6 = p = 1/3, and n + g + 8 = 0.06 then the convergence rate would equal 0.02. This implies that the economy moves halfway to steady state in about 35 years. Hence, in a Solow model output growth is a function of the initial level of income and of the ultimate determinants of the steady state. This implies that estimating an equation as (A3.8) would allow inferring the impact of each growth detenninant on the subsequent pattern of growth.32 This is because, the coefficient a, estimated on lagged output in equation (1), allows recovering the speed of convergence: A = — ln(l — a)/s, with 5=5.
