Higher Wages and Higher Prices

Inflation involves changes in both prices and wages, and can be

initially caused by either. Therefore, in this essay I will look at

two cases of inflation, one, which is caused by a change in aggregate

demand, and one, which is caused by a change in aggregate supply. Both

of these will have relation to prices and wages. I will then examine

the fiscal and monetary policy responses available to government in

either case.

In the first case, a rise in aggregate demand could lead to inflation.

This kind of inflation is referred to as demand-pull inflation. An

initial increase in the level of aggregate demand could be caused, for

example, by a rise in government spending. This would cause the

aggregate demand schedule to shift to the right, and the short-run

equilibrium point would move upwards and to the right along the

short-run aggregate supply curve. This would lead to a rise in prices

as well as an expansion in GDP. However, this would place the economy

above long-run aggregate supply, and therefore producing more than its

long-run potential. This means that the economy is operating with

unemployment lower than the natural rate, and the ensuing labor

shortages will lead to a rise in wages.

At first glance, there does not seem to be any reason why this should

lead to a process of inflation rather than just a one-off price rise.

The graph below illustrates what might be expected to happen:

Real GDP starts at Y0, with prices at P0. However, as aggregate demand

shifts outward from AD0 to AD1, real GDP moves to Y1, with an

accompanying price rise from P0 to P1. However, unemployment...

...creased output and therefore more

unemployment. Higher unemployment destroys the bargaining positions of

the Unions, and they will be unable to continue their wage demands.

Likewise, producers of raw materials will begin to feel the

contraction of their market as firms respond to higher prices by

reducing output, and so are unlikely to continue their price rises

unless government accommodates the shocks they are causing.

In conclusion, whether prices are driving up wages by demand-pull

inflation or wages are driving up prices by cost-push inflation, the

most sensible course of action for governments appears to be to

maintain strict control over the money supply. Perhaps sometimes it

might be preferable to relax monetary control slightly in order to

increase employment, but the price for this will always be inflation.
