the Solow (1956) model. This model is based on a neoclassical production function and the assumption of a constant exogenous savings rate. Given that in a closed economy savings are equal to investment, the process of capital accumulation depends on the savings rate which determines the investment rate. 5 illustrates how output increases after this increase in the savings rate.

A savings rate of 0% implies that no new investment capital is being created, so that the capital stock depreciates without replacement. Capital Dynamics in the Solow Model Because savings equals investment in the Solow model, equation (8) means that investment is also a constant fraction of output I t= sY t (9) which means we can re-state the equation for changes in the stock of capital dK t dt = sY t K t (10) In the Solow model the saving rate determines the steady-state levels of capital and output. Only one particular saving rate generates the Golden Rule steady state, i.e., the rate which maximises consumption per worker and, thus, economic well-being.

We will answer this question using a very simple aggregate (or economywide) model of economic growth.

"The Solow growth model shows how saving, population growth, and technological progress . affect the level of an economy's output and its growth over time" then a saving rate must be established . Bob Solow has carried out some of the most important work in macroeconomics by creating the Solow model of economic growth. His benchmark model is still taught in universities throughout the world.

Economic growth occurs when capital stock increases over time. There are some important implications or predictions of the Solow-Swan model of growth: 1. The growth rate of output in steady state is exogenous and is independent of the saving rate and technical progress. 2. If the saving rate increases, it increases the output per worker by increasing the capital per worker, but the growth rate of output is not affected. Question: How does the savings rate aﬀect the long-run average growth rate of a country? We will answer this question using a very simple aggregate (or economywide) model of economic growth.

Given that in a closed economy savings are equal to investment, the process of capital accumulation depends on the savings rate which determines the investment rate. From the standard Solow model, we know that steady-state output per capita is given by y = (s n+d) 1 . Steady-state consumption per worker is (1 s)y , or c = (1 s) s n+d 1 : From this expression, we see that an increase in the saving rate has two effects. First, it increases steady-state output per worker and therefore tends to increase consumption.
