The article examines how wages, prices, productivity, inflation, and unemployment in Italy changed from 1970 to 1994. The researchers used a special statistical method to analyze these relationships. They found that there was a shift in the balance between these factors, likely due to major changes in the Italian economy after 1979. By looking at different ways to model these changes, they concluded that the pattern of unemployment in Italy supports the idea that it can be influenced by past events.
