Is multiplier process in the short run or long run ?
Most of the time this process is long run because if there is new investment it will bring benefits in the long run. however, if economy is facing recession then a little new investment on the existing capital will be effective in the short run.

Explain Augmented Phillips curve :)
Phillips curvew.png

The Phillip's curve states that when the government tries to reduce the level of unemployment below that than natural unemployment rate, then due to this, inflation rises in an economy. This happens because when unemployment reduces, there is an increase in national income as more individuals are now employed and earn. This rises the aggregate demand for the economy which causes demand pull inflation.
However, there is a draw back of Phillip's curve and that is that sometimes, an economy experiences stagflation - a stiuation where unemployment is high and so is the rate of inflation - and phillip's curve does not define that.

It is a long run concept because the effect of multiplier cannot be achieved overnight. Imagine that government spends $100 million (injection) into an economy. It does that to provide jobs to the individuals. However, the places of work, or the salaries earned would not be able to take place in short-run, it is therefore a long-run concept which triggers 'accelerator' effect.

Why does the curve shift ??
