Solow Growth Model - Economics Assignment Help
The Solow Growth Model is also known as Exogenous Growth Model, Neo-classical Growth Model and Solow-Swan Growth Model. This concept is used to define what is called a model for long-run economic growth.
The model owes its important contributions to economists Robert Solow and T.W.Swan. They developed a relatively simple growth model which was fit with available U.S. economic growth with some success. Solow’s model emphasizes more on capital. Solow argued that new capital should be used instead of old capital. Solow believed that capital was produced from technology and technology improved overtime. So, Solow suggested that employing new capital would be much productive than the old capital.
This model was first developed by Sir Roy F. Harrod and Evsey Domar in 1946. Thus it was called Harrod-Domar Model. Solow’s Model is an extension of the above model. The extensions included
· Adding labor as factor of production.
· Requiring diminishing returns to labor and capital separately and constant returns to scale for both factors combined.
· Introducing a time-varying technology variable distinct from capital and labor.
Short-run implications:
Policy measures like tax cuts or investment subsidies can affect the steady level of output but not long-run growth rate. Growth is affected only in the short-run as the economy converges to the new steady output level. The rate of growth as the economy converges to the steady state is determined by the rate of capital accumulation. Capital accumulation can be determined by the savings rate (the proportion of output used to create more capital rather than being consumed) and the rate of capital depreciation.
Long-run implications:
In neoclassical models long-run growth rate is determined outside of the model. A common prediction of these models is that an economy will move toward steady growth rate, which in turn is dependent on the technological progress and the rate of labor force growth.

Phillips Curve - Economics Assignment Help
Phillips Curve - Economics Assignment Help
Phillips Curve deals with the relationship between unemployment and inflation in an economy. It was study on The British Economy between the periods 1861- 1957. The study states that the lower the rate of unemployment in an economy the higher the rate of increase in wages and the higher the rate of unemployment the lower the rate of increase in wages. It was observed that there was a stable tradeoff in the short run between unemployment and inflation, this has not been observed in the long run.
Phillips Curve was named after William Phillips, a New Zealand born economist wrote a paper in 1958 titled ‘The Relationship Between Unemployment and the Rate of Change of Money Wages in the United Kingdom 1861 - 1957’. This paper was published quarterly in the journal Economica. In this paper Philips discussed the inverse relationship between money wage changes and unemployment in the British economy over the period examined. Similar patterns were found in other countries and so this theory got accepted and the curve came to be known as The Phillips Curve.
Phillips observed that the lower the unemployment rate, the tighter the labor market and, therefore, the faster firms must raise wages to attract scarce labor. At higher rates of unemployment, the pressure reduced. Phillips’s “curve” represented the average relationship between unemployment and wage behavior over the business cycle. It showed the rate of wage inflation that would result if a certain level of unemployment continued for some time.
Although the discovery was based on the data for United Kingdom, researchers quickly extended this finding to other countries. Two years after the article was published, economists Paul Samuelson and Robert Solow published an article in the American Economic Review called “Analysis of Anti-inflation Policy” in which they showed similar negative correlation between inflation and unemployment in data for the United States. They reasoned that this correlation arose because low unemployment was associated with high aggregate demand, which in turn puts upward pressure on wages and prices throughout the economy.
Samuelson and Solow believed that the Phillips Curve gave valuable lessons to policy-makers of possible economic outcomes. By altering monetary and fiscal policy to influence aggregate demand, policymakers could choose any point on this curve. Point A offers High employment and low inflation and point B offers Low employment and high inflation.
