We survey a representative sample of U.S. individuals about how well leading academic theories describe their financial beliefs and decisions. We find substantial support for many factors hypothesized to affect portfolio equity share, particularly background risk, investment horizon, rare...

The 1997-99 financial crises in the emerging markets have brought to the foreground the concern about offshore investment funds and their possible role in exacerbating volatility in the markets they invest in. Offshore investment funds are alleged to engage in trading behaviors that are...

Investor sophistication has lagged behind the growing complexity of retail financial markets. To explore this, we develop a dynamic model to study the interaction between obfuscation and investor sophistication. Taking into account different learning mechanisms within the investor population, we...

We propose a rational theory of momentum and reversal based on delegated portfolio management. An investor can hold assets through an index or an active fund. Investing in the active fund involves a time-varying cost, interpreted as managerial perk or ability. The investor responds to an...

This paper studies how portfolios with a global investment scope are actually allocated internationally using a unique micro dataset on U.S. equity mutual funds. While mutual funds have great flexibility to invest globally, they invest in a surprisingly limited number of stocks, around 100. The...

Using a novel data of institutional investors' bond holdings, we examine a transmission of the crisis of 2007-2008 from the securitized bond market to the corporate bond market via joint ownership of these bonds by investors. We posit that, ceteris paribus, corporate bonds held by investors with...

We provide new empirical evidence suggesting that the marginal investor in mutual funds behaves differently across market conditions. If the marginal investor allocates capital across mutual funds rationally, then the relative performance of funds should be unpredictable. We find however that...

This paper investigates whether mutual fund families acting as trustees of 401(k) plans display favoritism toward their own funds. Using a hand-collected dataset on retirement investment options, we show that poorly-performing funds are less likely to be removed from and more likely to be added...

Participants in defined contribution (DC) retirement plans rarely adjust their portfolio allocations, suggesting that their investment choices and consequent money flows are sticky and not discerning. Yet, the participants' inertia could be offset by the DC plan sponsors, who adjust the plan's...

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...
