    Household Portfolio Rebalancing and Equity Market Fluctuations figure
    How investors adjust their portfolios in response to movements in asset prices and other shocks is a key input to asset pricing models, yet data limitations mean there is relatively little evidence on these behavioral responses, particularly for high-net-worth households. In Asset Demand of US Households (NBER Working Paper 32001), Xavier Gabaix, Ralph S. J.

    Segregation based on race and income is a defining feature of cities and schools across the United States. While Black Americans make up less than 14 percent of the overall population, the typical Black child lives in a neighborhood where Black families make up the majority of residents and attends a school where at least half their peers are also Black.1 These neighborhoods and schools also tend to have relatively high rates of poverty. Theory posits that segregation in...

    How Informative Are Risk-Adjusted Hospital Quality Measures? Figure
    Hospital quality indicators are intended to provide public information about differences in the quality of care across hospitals. The measures — such as 30-day mortality rates and 30-day hospitalization costs for admitted patients — are adjusted for the characteristics of each hospital’s patient population. In principle, these risk-adjusted indicators are not affected if a hospital treats especially unhealthy patients. If the risk adjustment is inadequate, however, the...
    Cesarean section (C-section) is the most common surgical procedure performed in the United States. Sarah Robinson, Heather Royer, and David Silver report that C-section rates for first-time, singleton births increased from 24 percent to 32 percent between 1989 and 2017 alongside significant changes in medical practices during this period. In 2001, for example, the American College of Obstetricians and Gynecologists began recommending C-sections for breech...

    C-Suite Differences: Public versus Privately Held Firms figure
    Private equity (PE) firms’ business model is to acquire privately held companies, to change their strategy and operations with the goal of improving profitability and growth, and ultimately to sell the companies for a profit.

In The Market for CEOs: Evidence from Private Equity (NBER...
