For example, if capital lasts an average o years, then the depreciation rate is 4% per year. The basic Solow Model shows that capital accumulation alone cannot explain sustained economic growth. The equilibrium rate of growth that can be achieved varies directly with the saving-income ratio and inversely with the capital-output ratio. From (1) we know that k = 2.5y; and from (2) we know that, δk = 0.1y. If technical progress is introduced (a shift of TP to TP’), then the day of doom is postponed, but not eliminated. Marx believed that capitalism would not end up in a quiet classical ‘stationary’ state; rather, it would break up with a ‘bang’ ‘when the expropriators are expropriated’. As an example, let s/v > n; this means that the capital stock is growing faster than the labour force and also faster than output. They argue that technological progress takes place as a beneficial by-product of certain economic activities which is called externality. New production function is written as: Y = F(K, L x E) where E is called the efficiency of labour which includes technological progress. The steady-state capital stock k* =9. Most government policies—patent laws, tax code, etc. 18.7 shows how depreciation depends on the capital stock. Below k* investment exceeds depreciation, so the capital stock grows. Thus, all profits are saved and in equilibrium we obtain V = J(=n) where n is the natural growth rate, which is assumed thus: the rate of growth is given by the rate of profit which is determined by the propensity to save of the profit earners. Macroeconomic equilibrium (national savings equal to investment) … 18.4. If g is high, then the number of efficiency units is growing quickly, and the amount of capital per efficiency unit tends to fall. Fig 18.10 shows steady-state output and depreciation as a function of the steady-state capital stock. You do not currently have access to this article. The economists started paying their attention toward economic stability after the Great Depression of 1930s and economic ruin caused by World War II. Steady-State consumption is maximized if: That is, at the Golden Rule level of capital, the net MPK (MPK – δ) equals the rate of growth of total output (n + g). Note that the KM model discards the production function approach of the neo-classical theory and introduces a technical progress function. Saving rate must be raised to reach the Golden Rule: Fig. There is one particular saving rate that produces the Golden Rule Steady-State, which maximises consumption and, thus, economic well-being of the people. Thus, by a suitable choice of processes and composition of output, the over-all capital-output ratio of the whole economy may be reduced to maximise the growth rate. We assume that, the population and the labour force grow at a constant rate n. Like depreciation, population growth reduces the capital stock per worker. But to reach the new steady-state requires an initial period of low consumption. Economic development means radical restructuring of the economy. Nicholas Kaldor is perhaps best known in the economics profession for his contribution to growth and distribution theory as part of the Cambridge (England) challenge to the neoclassical theory of growth and distribution, which itself was a response to the pessimism of Harrod concerning the possibility of long-run equilibrium growth. Hence, Marx gave the clarion call: ‘workers of the world unite’, as they have nothing to lose except their ‘chain’ and ‘the whole world to conquer’. Decision about reaching the Golden Rule Steady-State is difficult when the population changes over time. The Solow Model shows that sustained growth in standards of living can arise only from technological progress. The New Kaldor Facts: Ideas, Institutions, Population, and Human Capital† By Charles I. Jones and Paul M. Romer* In 1961, Nicholas Kaldor highlighted six “stylized’’ facts to summa-rize the patterns that economists had discovered in national income accounts and to shape the growth models being developed to explain them. 268 (Dec., 1957), pp. 18.12 shows what happens over time to output, consumption and investment when economy begins with more capital than the Golden Rule as the investment saving rate is reduced.
