We explore the relation between probability weighting and household portfolio underdiversification in a representative household survey, using custom-designed incentivized lotteries. On average, people display Inverse-S shaped probability weighting, overweighting the small probabilities of tail...

We test the relation between ambiguity aversion and five household portfolio choice puzzles: non- participation, low allocations to equity, home-bias, own-company stock ownership, and portfolio under- diversification. In a representative U.S. household survey, we measure ambiguity aversion using...

We develop a dynamic portfolio-choice model with illiquid alternative assets to analyze conditions under which the "Endowment Model," used by some large institutional investors such as university endowments, does or does not work. The alternative asset has a lock-up, but can be voluntarily...

We study how access to high-skill labor affects the outcomes of start-up firms. We obtain exogenous variation in firms' ability to access skilled labor by using win rates in H-1B visa lotteries. Relative to other firms that also applied for H-1B visas, firms with higher lottery win rates are...

Endowment payouts have become an increasingly important component of universities' revenues in recent decades. We test two leading theories of endowment payouts: (1) universities smooth endowment payouts, or (2) universities use endowments as self-insurance against financial shocks. In contrast...

Academic and practitioner research yields a proliferation of methods using size and value/growth attributes or factors to evaluate portfolio performance. We assess the relative merits of several of the most widely-used procedures, including variants of matched-characteristic benchmark portfolios...

Because of differences in accrued gains and investors' tax-sensitivity, capital gains "lock-in" varies across mutual funds even for the same stock at the same time. Using this variation, we show that tax lock-in affects funds' governance decisions. Higher tax lock-in decreases the likelihood a...

Charitable donations are an important revenue source for many institutions of higher education. We explore how donations respond to economic and financial market shocks, accounting for both supply and demand channels through which these shocks operate. In panel data with fixed effects to control...

Using an incentivized survey and a representative sample of investors, we elicit ambiguity attitudes toward a familiar company stock, a local stock index, a foreign stock index, and a crypto currency. We separately estimate ambiguity aversion (ambiguity preferences) and perceived ambiguity...
