Automated Business Cycle Dashboard

This dashboard provides real-time indicators of US labor market and business cycle conditions. It starts with three core labor market indicators: the unemployment rate, vacancy rate, and labor market tightness. These metrics jointly characterize the functioning of the labor market. From these, the dashboard calculates two metrics that quantify how far the labor market is from social efficiency: the full-employment rate of unemployment (FERU) and the unemployment gap. These two metrics are key determinants of optimal monetary policy and fiscal policy. ...
