Neglected Risks : The Psychology of Financial Crises
Gennaioli, Nicola - 2015
We model a financial market in which investor beliefs are shaped by representativeness. Investors overreact to a series of good news, because such a series is representative of a good state. A few bad news do not change investor minds because the good state is still representative, but enough...

Neglected Risks, Financial Innovation, and Financial Fragility
Gennaioli, Nicola - 2010
We present a standard model of financial innovation, in which intermediaries engineer securities with cash flows that investors seek, but modify two assumptions. First, investors (and possibly intermediaries) neglect certain unlikely risks. Second, investors demand securities with safe cash...

Myopia and Discounting
Gabaix, Xavier - 2017
We assume that perfectly patient agents estimate the value of future events by generating noisy, unbiased simulations and combining those signals with priors to form posteriors. These posterior expectations exhibit as-if discounting: agents make choices as if they were maximizing a stream of...

On the Interaction of Memory and Procrastination : Implications for Reminders
Ericson, Keith M. Marzilli - 2014
I examine the interaction between present-bias and limited memory. Individuals in the model must choose when and whether to complete a task, but may forget or procrastinate. Present-bias expands the effect of memory: it induces delay and limits take-up of reminders. Cheap reminder technology can...

Individual Laboratory-Measured Discount Rates Predict Field Behavior
Chabris, Christopher F. - 2008
We estimate discount rates of 555 subjects using a laboratory task and find that these individual discount rates predict inter-individual variation in field behaviors (e.g., exercise, BMI, smoking). The correlation between the discount rate and each field behavior is small: none exceeds 0.28 and...

Procrastination and Impatience
Reuben, Ernesto - 2007
There is a large body of literature documenting both a preference for immediacy and a tendency to procrastinate. O'Donoghue and Rabin (1999a,b, 2001) and Choi et al. (2005) model these behaviors as the two faces of the same phenomenon. In this paper, we use a combination of lab, field, and...
