February 2019Fully Closed: Individual Responses to Realized Gains and Losses
with Michaela Pagel: w25542
We use transaction-level data of portfolio trades and holdings linked to checking, savings, and settlement account transactions and balances to explore how individuals respond to realized capital gains and losses. We exploit plausibly exogenous sales due to mutual fund liquidations for identification. Specifically, we estimate the marginal propensity to reinvest out of one dollar received from a forced liquidation, when the investor either achieved a gain or a loss relative to his or her initial investment. Theoretically, if individuals held optimized portfolios, the marginal propensity to reinvest out of forced sales should be 100%. Individuals should just reinvest all of their liquidity immediately into a fund with similar characteristics. Empirically, individuals reinvest 83% on average...
September 2018Measurement Error in Imputed Consumption
with Scott R. Baker, Lorenz Kueng, Michaela Pagel: w25078
Because of limitations in survey-based measures of household consumption, a growing literature uses an alternative measure of consumer expenditures commonly referred to as "imputed consumption." This approach typically utilizes annual snapshots of household income and wealth from administrative tax registries to calculate household spending as the residual of the household budget constraint. In this paper we use transaction-level retail investment data to assess the measurement error that can result in imputed consumption due to intra-year changes in asset values and composition. We show that substantial discrepancies between imputed and actual spending can arise due to trading costs, asset distributions, variable trade timing, and volatile asset prices between two annual snapshots. While...
November 2017Who Falls Prey to the Wolf of Wall Street? Investor Participation in Market Manipulation
with Christian Leuz, Maximilian Muhn, Eugene Soltes, Andreas Hackethal: w24083
Manipulative communications touting stocks are common in capital markets around the world. Although the price distortions created by so-called “pump-and-dump” schemes are well known, little is known about the investors in these frauds. By examining 421 “pump-and-dump” schemes between 2002 and 2015 and a proprietary set of trading records for over 110,000 individual investors from a major German bank, we provide evidence on the participation rate, magnitude of the investments, losses, and the characteristics of the individuals who invest in such schemes. Our evidence suggests that participation is quite common and involves sizable losses, with nearly 6% of active investors participating in at least one “pump-and-dump” and an average loss of nearly 30%. Moreover, we identify several distinct...
Fresh Air Eases Work – The Effect of Air Quality on Individual Investor Activity
with Michaela Pagel: w24048
This paper shows that air quality has a significantly negative effect on the likelihood of individual investors to sit down, log in, and trade in their brokerage accounts controlling for investor-, weather-, traffic-, and market-specific factors. In perspective, a one standard deviation increase in fine particulate matter leads to the same reduction in the probability of logging in and trading as a one standard deviation increase in sunshine. We document this effect for low levels of pollution that are commonly found throughout the developed world. As individual investor trading can be a proxy for everyday cognitively-demanding tasks such as office work, our findings suggest that the negative effects of pollution on white-collar work productivity are much more severe than previously though...
