Price Rigidities and the Value of Public Information

Abstract

<p>Firms' inflexibility in adjusting output prices to economic shocks exacerbates information asymmetry with respect to firms' profits, but public information on firms' cost structure mitigates this problem. We construct a novel form of public information from economic statistics disclosed by the government and find that such public information significantly reduces inflexible-price firms' bid-ask spreads, the probability of informed trading, and analyst forecast dispersions, but these results do not hold for flexible-price firms. Security analysts seek more cost-related information during conference calls about inflexible-price firms, but such a phenomenon is observed less frequently if a firm's input cost is more publicly observable. In addition, stock markets react more strongly to earning news announced by inflexible-price firms, consistent with our intuition.<br></p>
