Does inflation make the labor market look tighter than it is?
Core argument: The authors argue that a burst of inflation reduces real wages on impact and, with costly worker search effort and sticky wages, incentivizes job-to-job transitions that raise aggregate vacancies without any additional labor market shocks.
We illustrate how inflation can cause a large rise in vacancies through increased job-to-job transitions—creating the appearance of a tight labor market without any additional labor market shocks. A burst of inflation, all else equal, reduces real wages on impact. Costly worker search effort and sticky wages imply that a burst of inflation reduces workers’ real wages and incentivizes job-to-job transitions that lead to a rise in aggregate vacancies. Figure 21 shows 9 periods when the vacancy-to-unemployment rate spiked sharply relative to the average. Four of the peaks—marked with a red circle— occurred during periods when the inflation rate was persistently above 6% and the unemployment rate was either high by historical standards (in the mid and late 1970s) or was relatively constant. Notice that the four periods denoted with the red circles are also periods where it has been shown that aggregate supply shocks were important drivers of the observed inflation.
