For decades, textbooks have explained inflation behavior with Friedman (1968)’s Phillips curve: the inflation rate depends on expected inflation and the deviation of unemployment from its natural rate. Yet this theory has always been controversial, and skepticism has been rampant in the decade ...

This paper surveys and modestly extends the theory of menu-cost models of the behavior of the aggregate price level after large-cost shocks. It does so in the context of an economy with a high underlying rate of inflation. It concentrates on the effect of large permanent and unexpected increases ...

Inflation unexpectedly ...

Today, emerging economies continue to experience higher inflation than developed ones, and their central banks deviate more frequently from inflation targets. These patterns ...

In the early 1970s when he had barely turned thirty years old Vittorio Corbo was already a legend of sorts among development economists.
