a. job market paper:

I analyze high-frequency price dynamics around earnings announcements for the largest 1,500 U.S. stocks between 2011 and 2015. Price discovery following earnings surprises mostly occurs in the after-hours market, following the earnings announcement, and is generally complete by 10 a.m. Eighty percent of the price response to earnings surprises in the after-hours market occurs upon arrival of the first trades. Price reactions are largely explained by earnings surprises and not by order flow, consistent with the theoretical view that news can incorporate prices instantly. Consistent with recent theoretical work on investor disagreement, the impact of earnings news on volatilities, spreads, and trade volumes is much more gradual than its impact on the conditional mean adjustment of prices. Moreover, hidden orders constitute a larger share of executed limit orders following earnings announcements than at other times. I relate these findings to recent theoretical work on the role of hidden liquidity and price discovery.

b. working papers:

We construct indices of media attention to macroeconomic risks including employment, growth, inflation, monetary policy, and oil prices. Attention rises around macroeconomic announcements and following changes in fundamentals over quarterly, annual, and business cycle horizons. The effect is asymmetric, with bad news raising attention more than good news. Attention relates to the stock market in two ways. First, increases in aggregate trade volume and volatility coincide with rising attention, controlling for announcements. Second, changes in attention prior to the unemployment announcement predict both the announcement surprise and stock returns on the announcement day. We conclude that media attention to macroeconomic fundamentals provides useful information beyond the dates and contents of macroeconomic announcements.

In an effort to increase transparency, the Chair of the Federal Reserve now holds a press conference following some, but not all, Federal Open Market Committee announcements. Press conferences are scheduled independently of economic conditions, and we show that they communicate little information. Evidence from equity and derivative markets demonstrates that investors lower their expectations of important announcements on days without press conferences, thereby constraining the actions of a committee that wants to avoid surprising markets. Using media coverage and Google searches, we show that investors shift attention away from announcements without press conferences. This inattention further hinders the Fed's attempts to coordinate market expectations and therefore prevents effective monetary policy. Correspondingly, we show that announcements not followed by press conferences convey significantly less price-relevant information.

*Our results support the arguments brought forward by the former president of the Federal Reserve Bank of Minneapolis Narayana Kocherlakota on the impact of having two classes of FOMC announcements.
