classical theory of inflation and unemployment relationship

In Classical economic theory, unemployment is seen as a sign that smooth labor market . price inflation tends to relieve some "sticky wage" unemployment. labor relations, and power are important, even the Classical idea. Different views on fiscal policy, unemployment, the role of government intervention, increase in aggregate demand (faster than growth in LRAS), will just cause inflation and Classical theory is the basis for Monetarism, which only concentrates on The Domino Effect · Relationship between stock market and economy. In the Keynesian model, once the full-employment level of output is reached and Philips Curve Showing Negative Relationship between Rates of Inflation and . Friedman put forward a theory of adaptive expectations according to which.

Similarly, some commentators think inflation occurs when the government increases a particular tax say, a value-added tax on goods and services r GST by x per cent and this is passed on by firms in the form of higher prices for goods and services.

None of these examples constitute inflation. Given they all involve a rise in prices, each example would constitute what we would call a necessary condition for an inflationary episode. But none of these examples represent a sufficient condition. Observing a price rise alone will not be sufficient to justify the conclusion that one is observing as being an inflationary episode. Inflation is the continuous rise in the price level.

That is, the price level has to be rising each period that you observe it. If the price level rises by 10 per cent every month, for example, then we would be observing an inflationary episode.

In this case, the inflation rate would be considered stable — a constant or proportionate increase in the price level per period. If the price level was rising by 10 per cent in month one, then 11 per cent in month two, then 12 per cent in month three and so on, then we would be observing an accelerating inflation. Alternatively, if the price level was rising by 10 per cent in month one, 9 per cent in month two etc then you have falling or decelerating inflation.

If the price level starts to continuously fall then we call that a deflationary episode. The term hyper-inflation is reserved for inflationary episodes, which rapidly exponentiate. There have been few instances of this problem in recorded history.

Thus, a price rise can become inflation if it is repeating but a once-off price rise is not considered to be an inflationary episode. We might also define a normal price level as being the prices firms are willing to supply at when they are operating at normal capacity.

This is the price that satisfies the desired mark-up, which aims to generate a profit rate that will satisfy the strategic aspirations of the firms. Refresh your memory of the discussion of mark-up pricing in Chapter 9 if you are uncertain of the way in which firms relate their pricing to other targets.

This is particularly the case during a recession. When there are very depressed levels of activity, firms might offer discounts or sales in order to increase capacity utilisation. They thus temporarily suppress their profit margins as a means of maintaining their market share.

As demand conditions become more favourable the firms start withdrawing the discounts and the frequency of sales decrease and prices return to those levels that offer the desired rate of return to firms at normal levels of capacity utilisation.

We would not consider these cyclical adjustments in prices, where they occur to constitute inflation. Such convertibility was suspended in at the outset of the Napoleonic War and did not resume until The intervening period of inconvertible paper was initially marked by rampant inflation.

Subsequently, in the period between andmany country banks in England failed and this led to a destruction of country-bank paper a form of money and a sharp contraction in the money supply. The deflation that resulted imposed harsh effects on the unemployed and members of the working class which became worse with the resumption of cash payments at the gold parity, which existed prior to the suspension. Somewhat earlierthe Scottish economist, David Hume wrote an essay entitled — Of Money — and outlined a theory that is very reminiscent of what we later called the Phillips curve relationship — the trade-off between inflation and unemployment.

Hume said that the expansionary effect of an increase in money supply begins via a rise in cash balances in the economy. There is a presumption that the economy is at less than full employment and, with excess capacity in the labour market, the higher spending leads to firms increasing output.

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. 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[13] 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. Today[ edit ] U. 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. This is because in the short run, there is generally an inverse relationship between inflation and the unemployment rate; as illustrated in the downward sloping short-run Phillips curve. In the long run, that relationship breaks down and the economy eventually returns to the natural rate of unemployment regardless of the inflation rate.

In the long run, this implies that monetary policy cannot affect unemployment, which adjusts back to its " natural rate ", also called the "NAIRU" or "long-run Phillips curve". In macroeconomics, classical economics assumes the long run aggregate supply curve is inelastic; therefore any deviation from full employment will only be temporary. The Classical model stresses the importance of limiting government intervention and striving to keep markets free of potential barriers to their efficient operation.

Keynesians argue that the economy can be below full capacity for a considerable time due to imperfect markets. Keynesians place a greater role for expansionary fiscal policy government intervention to overcome recession.

Shape of long-run aggregate supply A distinction between the Keynesian and classical view of macroeconomics can be illustrated looking at the long run aggregate supply LRAS. This has important implications.

The classical view suggests that real GDP is determined by supply-side factors — the level of investment, the level of capital and the productivity of labour e.

They argue that the economy can be below full capacity in the long term. Keynesians argue output can be below full capacity for various reasons: Once there is a fall in aggregate demand, this causes others to have less income and reduce their spending creating a negative knock-on effect.

A paradox of thrift. In a recession, people lose confidence and therefore save more. By spending less this causes a further fall in demand. Keynesians argue greater emphasis on the role of aggregate demand in causing and overcoming a recession. Demand deficient unemployment Because of the different opinions about the shape of the aggregate supply and the role of aggregate demand in influencing economic growth, there are different views about the cause of unemployment Classical economists argue that unemployment is caused by supply side factors — real wage unemployment, frictional unemployment and structural factors.

They downplay the role of demand deficient unemployment.
