Ambiguity and Investor Behavior
(2020-11-24)We relate time-varying aggregate ambiguity (V-VSTOXX) to individual investor trading. We use the trading records of more than 100,000 individual investors from a large German online brokerage from March 2010 to December ... -
Belief Formation and Belief Updating under Ambiguity: Evidence from Experiments
(2019-09-21)Decisions under ambiguity depend on both the belief regarding possible scenarios and the attitude towards ambiguity. This paper exclusively focuses on beliefs, measured independent from attitudes. We use laboratory experiments ... -
Horizontal Industry Relationships and Return Predictability
(2019-08-09)It has been documented that vertical customer-supplier links between industries are the basis for strong cross-sectional stock return predictability (Menzly and Ozbas (2010)). We show that robust predictability also arises ... -
Implied Volatility Duration: A Measure for the Timing of Uncertainty Resolution
(2020-01-27)We introduce Implied Volatility Duration (IVD) as a new measure for the timing of uncertainty resolution, with a high IVD corresponding to late resolution. Portfolio sorts on a large cross-section of stocks indicate that ... -
Measuring Ambiguity Aversion: A Systematic Experimental Approach
(2014-06-20)This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ... -
On the (ir)relevance of monetary incentives in risk preference elicitation experiments
(2020-08-31)Incentivized experiments in which individuals receive monetary rewards according to the outcomes of their decisions are regarded as the gold standard for preference elicitation in experimental economics. These task-related ... -
Optimal Carbon Abatement in a Stochastic Equilibrium Model with Climate Change
(2018-09-24)This paper studies a dynamic stochastic general equilibrium model involving climate change. Our framework allows for feedback effects on the temperature dynamics. We are able to match estimates of future temperature ... -
Predictability and the Cross-Section of Expected Returns: A Challenge for Asset Pricing Models
(2021-01-22)"Many modern macro finance models imply that excess returns on arbitrary assets are predictable via the price-dividend ratio and the variance risk premium of the aggregate stock market. We propose a simple empirical test ... -
Separating the Effects of Beliefs and Attitudes on Pricing under Ambiguity
(2021-03-10)The pricing of an ambiguous asset, whose cash flow stream is uncertain, may be affected by three factors: the belief regarding the realization likelihood of cash flows, the subjective attitude towards risk, and the attitude ... -
Stochastic Differential Utility as the Continuous-Time Limit of Recursive Utility
(2013-05-10)We establish a convergence theorem that shows that discrete-time recursive utility, as developed by Kreps and Porteus (1978), converges to stochastic differential utility, as introduced by Duffie and Epstein (1992), in the ... -
Women form social networks more selectively and less opportunistically than men
(2017-03-01)We test two hypotheses, based on sexual selection theory, about gender differences in costly social interactions. Differential selectivity states that women invest less than men in interactions with new individuals. ...
