A growing literature uses the Russell 1000/2000 reconstitution event as an identification strategy to investigate corporate finance and asset pricing questions. To implement this identification strategy, researchers need to approximate the ranking variable used to assign stocks to indexes. We...

Exchange-traded funds (ETFs) are the most prominent financial innovation of the last three decades. Early ETFs offered broad-based portfolios at low cost. As competition became more intense, issuers started offering specialized ETFs that track niche portfolios and charge high fees. Specialized...

Over nearly a quarter of a century, ETFs have become one of the most popular passive investment vehicles among retail and professional investors due to their low transaction costs and high liquidity. By the end of 2016, the market share of ETFs topped over 10% of the total market capitalization...

Large institutional investors own an increasing share of equity markets. We conjecture that a financial market in which large institutions dominate operates differently than a market populated by smaller independent investors. To support this view, we show that funds within the same family...

We study whether exchange traded funds (ETFs)--an asset of increasing importance--impact the volatility of their underlying stocks. Using identification strategies based on the mechanical variation in ETF ownership, we present evidence that stocks owned by ETFs exhibit significantly higher...

In data from an account aggregator, households increase consumption when they receive (expected) tax refunds, as if they are liquidity constrained. However, this behavior is not due to liquidity constraints or hand-to-mouth behavior. These same households smooth consumption when making payments...

Despite awareness of the detrimental impact of CO₂ pollution on the world climate, countries vary widely in how they design and enforce environmental laws. Using novel micro data about firms' CO₂ emissions across countries, we document that firms headquartered in countries with strict...

We show that there exists significant heterogeneity across US households in how uncertain they are in their expectations regarding personal and macroeconomic outcomes, and that uncertainty in expectations predicts households' choices. Individuals with lower income or education, more precarious...

We infer the role of price expectations in forming the U.S. housing boom in the early- 2000s from examining housing inventories. We use a reduced form model to show that agents invest in vacant homes when they anticipate prices will increase. Empirically, vacancy can discriminate between price...

We explore the actions of financially distressed banks in two distinct periods that include financial crises (1985-1994, 2005-2014) and differ in bank regulations, especially concerning capital requirements and enforcement. In contrast to the widespread belief that distressed banks gamble for...
