This paper examines how initial public offerings (IPOs) affect firms' internal organization. We find that IPO firms become more hierarchical and standardized organizations, characterized by additional layers, more managers, smaller control spans, and larger administrative functions. These changes occur mostly in preparation for the IPO and can be only partially explained by growth. IPO firms with greater human capital risk experience larger hierarchical changes. Hierarchical changes help firms standardize employee roles and formalize internal processes. Our results suggest that firms reorganize to reduce their dependence on key individuals' human capital when transitioning to public markets.

We introduce a simple measure of informed trading risk, , the residual to liquidity quote‐improvement‐to‐deterioration ratio times . When facing with increased informed trading risk, liquidity providers compete less to provide liquidity, reducing their undercutting activity. Reductions in undercutting leave footprints in trade and quote data that are captured by . Unlike prior measures, is easy to construct, can be computed intraday, and is orthogonal to liquidity. The measure outperforms prominent existing alternatives in reflecting the extent of information asymmetry before earnings announcements, predicting unscheduled press releases, and identifying informed trading spillovers around them.

Using unique, daily, account‐level data, we investigate deposit outflows and inflows in a distressed bank. We observe an outflow of uninsured depositors following bad regulatory news. Both regular and temporary deposit insurance reduce outflows. We provide important new evidence that, simultaneous with deposit outflows, deposit inflows are first order. Uninsured deposit outflows were largely offset with new insured deposit inflows as the bank approached failure, with the bank increasing term deposit rates. This phenomenon holds in a large sample of banks that faced regulatory action, suggesting that insured deposit inflows are an important mechanism that weakens depositor discipline.

We study the role of risk preferences and frictions in portfolio choice using variation in 401(k) default options. Patterns of active choice in response to different default funds imply that, absent participation frictions, 94% of investors prefer holding stocks, with an equity share of retirement wealth declining with age—patterns markedly different from observed allocations. We use this quasi‐experiment to estimate a life‐cycle model and find a relative risk aversion of 2.5, elasticity of intertemporal substitution (EIS) of 0.25, and $160 portfolio adjustment cost. The results suggest that low levels of stock market participation in retirement accounts are due to participation frictions rather than nonstandard preferences such as loss aversion.
