Do Higher Involvement Rates Enhance Or Lower Inflation?
The fact that inflation is thence stable when involvement rates are stuck at nothing has profound implications. If inflation is stable at a nothing peg, it must hold out stable at a higher peg equally well, which agency raising involvement rates must sooner or afterward heighten inflation. The opened upwardly question, which this newspaper goes after, is whether inflation tin temporarily refuse when involvement rates rise. (Graphs from an before spider web log ship service here.)
Classical "Keynesian" or "Monetarist" models tell that inflation is unstable inwards a peg. They must hold out wrong. "New-Keynesian" models tell that inflation is stable inwards a peg, a proficient signal inwards their favor. The of import divergence is rational expectations. If people create a auto looking inwards the raise thought mirror, cars are unstable in addition to veer off the road. If people aspect forward, in addition to then cars are stable in addition to larn dorsum on the route on their own.
But the measure new-Keynesian model too predicts that inflation goes upwardly if involvement rates rise, equally shown inwards the graph. Interest rates are blue, inflation is red, output is black. The dashed business is when people know the rising is coming, the company business for when it's a surprise. Raising rates does lower output, only equally y'all thought.
The newspaper tries everything to revive the thought that higher involvement rates lower inflation, without luck.
The measure new-Keynesian model accounts good for the fact that inflation has been stable at a nothing involvement charge per unit of measurement peg. However, If the Fed raises nominal involvement rates, the same model model predicts that inflation volition smoothly rise, both inwards the brusk run in addition to long run. This newspaper presents a serial of failed attempts to escape this prediction. Sticky prices, money, backward-looking Phillips curves, alternative equilibrium alternative rules, in addition to active Taylor rules produce non convincingly overturn the result. The show for lower inflation is weak. Perhaps both theory in addition to information are trying to tell us that, when weather condition including adequate fiscal-monetary coordination operate, pegs tin hold out stable in addition to inflation responds positively to nominal involvement charge per unit of measurement increases.
