Average hourly earnings rose seven cents in February, the fourth consecutive month that over-the-year increases were above 4.0% and evidence earnings have elevated off a two-year plateau, a senior Bureau of Labor Statistics analyst said Friday morning.

Help supply did not decline, nor did construction, when both could have been expected to.
