We classify a unique and comprehensive dataset of corporate press releases into topics and study the market reaction to various types of news. While confirming prior findings regarding strong stock price responses to financial news, we also document significant reactions to news about corporate strategy, customers and partners, products and services, management changes, and legal developments. Consistent with regulators' expectations, the level of informational asymmetry in the market declines following most types of press releases. At the same time, return volatility frequently increases in the post-announcement period, which we show can be attributed to higher levels of valuation uncertainty.

We empirically assess the effect of reserve accumulation as a result of quantitative easing (QE) on bank-level lending and risk taking activity. To overcome the endogeneity of bank-level reserve holdings to banks' other portfolio decisions, we employ instruments made available by a regulatory change that strongly influenced the distribution of reserves in the banking system. Consistent with theories of the portfolio substitution channel in which the transmission of QE depends in part on reserve creation itself, we document that reserves created in two distinct QE programs led to higher total loan growth and an increase in the share of riskier loans, such as commercial real estate, construction, C&I, and consumer loans, within banks' loan portfolios.
