Inflation and Unemployment - Foundation For Teaching Economics
The Phillips curve is a single-equation econometric model, named after William Phillips, describing a historical inverse relationship between rates of unemployment While there is a short run tradeoff between unemployment and inflation. In the article, A.W. Phillips showed a negative correlation between the rate of unemployment and the rate of inflation – the years with high unemployment. Inflation and unemployment are two key elements when evaluating a whole economy and it is also easy to get those figures from National Bureau of Statistics .
In this he followed eight years after Samuelson and Solow  who wrote "All of our discussion has been phrased in short-run terms, dealing with what might happen in the next few years. It would be wrong, though, to think that our Figure 2 menu that related obtainable price and unemployment behavior will maintain its same shape in the longer run. What we do in a policy way during the next few years might cause it to shift in a definite way. Unemployment would then begin to rise back to its previous level, but now with higher inflation rates.
This result implies that over the longer-run there is no trade-off between inflation and unemployment.
Trade off between unemployment and inflation
This implication is significant for practical reasons because it implies that central banks should not set unemployment targets below the natural rate. Work by George AkerlofWilliam Dickensand George Perry implies that if inflation is reduced from two to zero percent, unemployment will be permanently increased by 1.
This is because workers generally have a higher tolerance for real wage cuts than nominal ones. For example, a worker will more likely accept a wage increase of two percent when inflation is three percent, than a wage cut of one percent when the inflation rate is zero.

There is no single curve that will fit the data, but there are three rough aggregations——71, —84, and —92—each of which shows a general, downwards slope, but at three very different levels with the shifts occurring abruptly. The theory goes under several names, with some variation in its details, but all modern versions distinguish between short-run and long-run effects on unemployment.
Lower real interest rates provide incentives for people to save less and to borrow more. Real interest rates normally are positive because people must be compensated for deferring the use of resources from the present into the future. Higher interest rates reduce business investment spending and consumer spending on housing, cars, and other major purchases.

Policies that raise interest rates can be used to reduce these kinds of spending, while policies that decrease interest rates can be used to increase these kinds of spending. Consequently, an initial change in spending consumption, investment, government, or net exports usually results in a larger change in national levels of income, spending, and output.
Unemployment imposes costs on individuals and nations. Unexpected inflation imposes costs on many people and benefits some others because it arbitrarily redistributes purchasing power. Inflation can reduce the rate of growth of national living standards, because individuals and organizations use resources to protect themselves against the uncertainty of future prices.How Inflation Affects the Unemployment Rate
Inflation reduces the value of money. The unemployment rate is the percentage of the labor force that is willing and able to work, does not currently have a job, and is actively looking for work. The unemployment rate is an imperfect measure of unemployment because it does not 1 include workers whose job prospects are so poor that they are discouraged from seeking jobs, or 2 reflect part-time workers who are looking for full-time work.
Unemployment rates differ for people of different ages, races, and sexes. This reflects differences in work experience, education, training, and skills, as well as discrimination. Unemployment can be caused by people changing jobs, by seasonal fluctuations in demand, by changes in the skills needed by employers, or by cyclical fluctuations in the level of national spending.
Full employment means that the only unemployed people in the economy are those who are changing jobs. The consumer price index CPI is the most commonly used measure of price-level changes.
It can be used to compare the price level in one year with price levels in earlier or later periods. Expectations of increased inflation may lead to higher interest rates.
The costs of inflation are different for different groups of people. Unexpected inflation hurts savers and people on fixed incomes; it helps people who have borrowed money at a fixed rate of interest. Inflation imposes costs on people beyond its effects on wealth distribution because people devote resources to protect themselves from expected inflation.
Monetarist View The Phillips curve is criticised by the Monetarist view. Monetarists argue that increasing aggregate demand will only cause a temporary fall in unemployment. Monetarist Phillips Curve Diagram Rational expectation monetarists believe there is no trade-off even in the short-term. They believe if the government or Central Bank increased the money supply, people would automatically expect inflation, so there would be no improvement in real GDP.
Falling Inflation and Falling Unemployment In some periods, we have seen both falling unemployment and falling inflation. For example, in the s, unemployment fell, but inflation stayed low. This suggests that it is possible to reduce unemployment without causing inflation. However, you could argue there is still a potential trade-off except the Phillips curve has shifted to the left, because there is now a better trade-off.
It also depends on the role of Monetary policy. Rising Inflation and Rising Unemployment It is also possible to have a rise in both inflation and unemployment. If there was a rise in cost-push inflationthe aggregate supply curve would shift to the left; there would be a fall in economic activity and higher prices.
