The sensitivity of earnings to value added shocks
The first row in Panel A reports the IV estimate of the sensitivity of wages to value added
shocks (bu for permanent shocks and bυ for transitory shocks). J-test is the test of overidentifying
restrictions. F-test is the test of joint insignificance of excluded instruments. E (∆ωyz'∆^>ijt-τ)
is an estimate of the autocovariance of wage shocks of order τ; E (∆εjt∆εjt-τ) an estimate of
the autocovariance of value added shocks of order τ; E (∆ω⅛'t∆εjt-τ) an estimate of the cross-
covariance of wage and value added shocks of order τ. σ^l, σ^, σ∣ and σjl are EWMD estimates
of the variances of value added permanent shocks, value added transitory shocks, wage permanent
shocks and wage transitory shocks, respectively. ρ is an estimate of the MA coefficient of earnings.

Asymptotic standard errors are reported in parenthesis. The Ratio is calculated as:
and measures the amount of earnings variability attributable to value added shocks.
