This paper considers the problem of jointly decomposing a set of time series variables into cyclical and trend components, subject to sets of stochastic linear restrictions among these cyclical and trend components. We derive a closed form solution to an ordinary problem featuring homogeneous...

The empirical analysis indicates that in the Federal Republic the unemployed primarily influence the relationship between the level of real wages and productivity, rather than the growth of wages. This result suggests a distinction between an equilibrium natural rate of unemployment, which is...

The methodology used in this paper has three distinguishing features: the natural rate of unemployment and potential output are jointly estimated; estimation integrates wage and price data with “real” and structural data; and third, the methodology encompasses many of the methods found in the...

We study the properties of the IMF-WEO estimates of real-time output gaps for countries in the euro area as well as the determinants of their revisions over 1994-2017. The analysis shows that staff typically saw economies as operating below their potential. In real time, output gaps tend to have...

In the last few decades, real GDP growth and investment in advanced countries have declined in tandem. This slowdown was not the result of weak demand (there has been no shift along the Okun curve), but of a decline in potential output growth (which has shifted the Okun curve to the left). We...

Korea's economy has leaped to high-income status thanks to several decades of sustained high growth. However, population aging and shifts in global demand provide headwinds for future growth and Korea now faces the effects of COVID-19 on economic activity. This paper asseses the expected drag on...
