W consider two-part pricing of a service offered to risk-averse buyers subject to demand uncertainty. Buyers subscribe to the contract before resolution of the uncertainty. Sellers set two-part prices that trade off between insuring buyers against the uncertainty and the ex post deadweight loss from inefficient usage. If marginal and total benefits from the service are positively correlated (a ...

Our objective in this article is to study analytically the effect of borrowing constraints on asset returns. We explicitly characterize the equilibrium for an exchange economy with two agents who differ in their risk aversion and are prohibited from borrowing. In a representative-agent economy with CRRA preferences, the Sharpe ratio of equity returns and the riskfree rate are linked by the risk...

Shortfall aversion reflects the higher utility loss of a spending cut from a reference point than the utility gain from a similar spending increase, in the spirit of Prospect Theory’s loss aversion. This paper posits a model of utility of spending scaled by a function of past peak spending, called target spending. The discontinuity of the marginal utility at the target spending corresponds to s...

At rst glance, there would appear to be no relationship between Bell's (1988) concept of one-switch utility functions and that of a stronger measure of risk aversion due to Ross (1981). We show however that speci c assumptions about the behavior of the stronger measure of risk aversion also give rise to the linex utility function which belongs to the class of one-switch utility functions. In pa...

Defined as increased sensitivity to losses, loss aversion is often conceptualized as a cognitive bias. However, findings that loss aversion has an attentional or emotional regulation component suggest that it may instead reflect differences in information processing. To distinguish these alternatives, we applied the drift-diffusion model (DDM) to choice and response time (RT) data in a card gam...

the relationship between finance and other social sciences as known behavioural finance, evaluate investors to the decision-making process and their reaction to different conditions of financial markets deals. in this study assumed that analysts are specialist in fundamental and technical analysis and then influence their personality characteristics is evaluated on their performance. statistica...

Loss aversion refers to the fact that people are distinctively more sensitive to losses than to gains. Loss averse agents are very risk averse around the reference point and exhibit asymmetric responses to positive and negative income shocks. In an otherwise standard RBC model, I study loss aversion in both consumption alone and consumption-and-leisure together. My results indicate that how los...

We analyze a family of portfolio management problems under relative performance criteria, for fund managers having CARA or CRRA utilities and trading in a common time horizon in log-normal markets. We construct explicit time-independent equilibrium strategies for both the finite population games and the corresponding mean field games, which we show are unique in the class of time-independent eq...
