Abstract: 
We study real efficiency implications of disclosing public information in a model with multiple dimensions of uncertainty where market prices convey information to real decision makers. Disclosing public information has a positive direct effect of providing new information and an indirect effect of changing price informativeness, whose sign depends on the type of information being disclosed. Paradoxically, when disclosure is about a variable that real decision makers care to learn, the indirect effect is negative. Moreover, in markets which are effective in aggregating private information, the negative indirect effect dominates the direct effect, implying that better disclosure harms real efficiency.
