Over recent months, the Bureau of Labor Statistics (BLS) has revised upward its initial estimates of the monthly change in nonfarm payroll employment.

This pattern of positive revisions suggests that the BLS might be having trouble pinning down initial estimates of job gains in the early stages of an expansion. It also cautions us against placing too much weight on very early, sometimes unreliable estimates of macroeconomic data.View the Full Report
