We theoretically show that there is a fundamental disconnect between the disposition effect, i.e., investors’ tendency to sell winning assets too early and losing assets too late, and its common empirical measure, namely a positive difference between the proportion of gains and losses...

Cash is an important means of transaction, generally assumed to be fungible. However, behavioral economics and consumer research show that "cash in hand", physically holding on to cash and then handing it away, affects purchasing decisions. I study how cash in hand influences decisions in a...

We study the investor behavior on a leading peer-to-business lending platform and find evidence of two new investment biases - a default shock bias and a deep market bias. First, we find investors to stop investing in new loans and to cease from diversifying their portfolio after experiencing a...

Attention utility is the hedonic pleasure or pain derived purely from paying attention to information. Using data on brokerage account logins by individual investors, we show that individuals devote disproportionate attention to already-known positive information about the performance of...

A large fraction of households have very little savings buffer and are therefore vulnerable to financial shocks. This paper examines whether a social norm nudge can induce such households to save more. We ran a large-scale field experiment at a retail bank in the Netherlands. We find that...

We show that the disposition effect-the tendency of investors to hold losers and sell winners-can be a source of overconfidence. We find experimental evidence that individuals update beliefs about their own investment ability based on realized gains and losses rather than the overall performance...

We test for skewness preferences in a large set of observational panel data on online poker games (n=4,450,585). Each observation refers to a choice between a safe option and a binary risk of winning or losing the game. Our setting offers a real-world choice situation with substantial incentives...

We are the first to analyze the effect of terror on stock markets by terror ideology. Surprisingly, we find that Islamist terror attacks created significant negative abnormal returns in American and European markets, but the stock market effects of other terror attacks were almost nil. For our...

Modern life offers nearly unbridled access to information; it is the harnessing of this information to guide decision-making that presents a challenge. We study how one individual may try to shape the way another person interprets objective information by proposing a causal explanation (or...

We investigate financial experts’ beliefs about climate risk pricing and analyze how those beliefs influence stock return expectations. In a comprehensive survey, we elicit experts’ beliefs using both structured and open-ended questions. We establish that most experts share the view that...
