These data are collected by the U.S. Bureau of Labor Statistics as part of its monthly Current Population Survey. 2  Aaronson and Sullivan (2001). 2  BIS central bankers’ speeches  since then. 3 Among the many robustness analyses they performed, their models produce nearly the same trend for labor force participation as they have since 2001. 4 Depending on the details of the specification, Chicago Fed economists estimate that at the end of the second quarter of 2014, the labor force participation rate was between 1/2 and 1–1/4 percentage points below trend. Furthermore, the participation rate was as much as 3/4 of a percentage point below predictions based on its historical relationship with the unemployment rate. This disparity suggests that there likely is an extra margin of slack in labor markets beyond that indicated by the unemployment rate alone. It is interesting to dig further into these “labor force participation gaps.” Virtually all the gap during this cycle has been due to withdrawal from the labor market of workers without a college degree. By contrast, a participation gap never materialized for college graduates, even during the depths of the recession. There is no simple explanation for this striking contrast. It could be yet another symptom of long-running but difficult-to-model trends in the economy, such as job polarization and changes in social programs, which particularly impact the lower-skill work force. 5 Regardless, the divergent work behavior across education groups strikes me as an important fact and deserving of much further research attention.
Since then, we have made significant progress in moving the unemployment rate back to a more normal number. Yet, at 6.1 percent, it remains too high. And, as we have heard all morning, other measures of labor market activity remain suppressed. We have underperformed on the inflation front as well. Since 2008, year-over-year total inflation as measured by the Personal Consumption Expenditures Price Index (PCE) has averaged just 1.4 percent, well below its 2 percent target. Today, PCE inflation stands at 1–1/2 percent and is expected to move up only slowly toward the FOMC’s target. Nonetheless, we have come a long way in healing the injuries the financial crisis inflicted. Certainly monetary policy has been doing some heavy lifting. The Federal Reserve responded quickly to the unfolding recession by cutting the fed funds rate to near zero by December 2008. At the zero lower bound (ZLB), we then turned to unconventional measures, such as large-scale asset purchases and forward guidance about the federal funds rate to provide further accommodation. In the fall of 2012, with the unemployment rate hovering stubbornly at around 8 percent and core inflation steadily drifting lower than our 2 percent target, the Fed introduced open-ended asset purchases and, later, forward guidance that related federal funds rate actions to thresholds explicitly expressed in terms of our policy goals. Together, these efforts have helped the economy make impressive progress toward our employment mandate and appear to be moving us closer to our 2 percent inflation target as well.
