### Summary and purpose
- Following the global financial crisis, significant uncertainty has existed around the U.S. economy’s steady state equilibrium.
- The paper uses a factor model to provide a new approach to estimating “the stars” (i.e. the neutral interest rate, maximum employment, and the level and growth rate of potential output) that are most consistent with a medium-term equilibrium where inflation converges to the FOMC’s two percent target.
- The approach is applicable to any country with an inflation targeting central bank.
- The model explicitly incorporates estimates of the extensive margin of slack in the labor market, which has proven to be an important factor in describing the post-financial crisis landscape.

### Methodology and key modeling features
- Uses a factor model to estimate latent equilibrium variables (“the stars”).
- Targets a medium-term equilibrium characterization where inflation converges to the FOMC’s two percent target.
- Explicit incorporation of the extensive margin of labor market slack into the estimation framework.

### Major findings and implications
- The factor-model approach yields estimates of:
  - the neutral interest rate,
  - maximum employment,
  - the level and growth rate of potential output,
  that are consistent with inflation converging to the FOMC’s two percent target.
- Including the extensive margin of labor market slack is important for describing post-financial crisis dynamics.

### Applicability and scope
- Applicable to any country with an inflation targeting central bank.
- Focus primarily on the U.S. economy in the context of post-global financial crisis uncertainty.

### Subjects and keywords
- Subject: Business cycles, Inflation, Inflation targeting, Output gap, Productivity
- Keywords: inflation expectation, inflation gap, output gap estimate, output gap estimation certainty, PCE inflation, WP
