The article analyzes unemployment and potential output in Finland from 1982 to 1996. By using statistical methods, the researchers found that the Non Accelerating Inflation Rate of Unemployment (NAIRU) and potential output varied over time. The NAIRU was higher than the actual unemployment rate until 1991, but then decreased to a level between 8 and 9.5% in the 1990s. The study suggests that these variables fluctuate less in the long run compared to actual unemployment and output levels.
