The Phillips curve is shallow when so-called nominal rigidities in the economy are common and strong --and thus when prices respond slowly and sluggishly to changes in demand.
Nominal rigidities are strong when labor unions have many members, when long-term contracts contain few automatic price escalator clauses, when there are many long-term contracts, and when people expect inflation to be constant and thus do not look for changes in inflation.
When the Phillips curve is shallow, even a large change in unemployment will have only a small effect on the rate of inflation.
