Does the market matter for more than investment?

Market effects on corporate investment are well documented. Low disagreement implies high investment, but we know little about what high disagreement implies, other than the implied flip side (low investment). This paper adds to this literature in several ways. A new dimension of corporate behavior that is related to disagreement is documented. Higher disagreement precedes a lower cost structure. Empirical tests reveal that the results are not driven by forced production efficiency due to financial constraints.
