The equation for the Phillips curve is (inflation) = (expected inflation) - B * (cyclical unemployment rate) + (error).

Problem : Define stagflation and explain its implications.

Stagflation is the situation in which both inflation and unemployment increase. It is a phenomenon that raises questions about the general applicability of the Phillips curve.

Problem : How is the Phillips curve best used?

The Phillips curve is useful not as a means of picking an unemployment and inflation rate pair, but rather as a means of understanding how unemployment and inflation might move given historical data.
