Theory suggests that the level of uncertainty may affect the output and employment decisions of firms, although in general the sign of the effect is ambiguous. A GARCH-M estimator is used to model the conditional variance of GDP. This measure is then employed in backward- and forward-looking specifications of the demand for manufacturing labor. The results are that the level of aggregate uncertainty has a significant negative effect on manufacturing employment and that the forward-looking dynamic specification may be rejected against a backward-looking alternative.
