The only step in the existence proof that differs from the risk neutral
case considered by Dasgupta and Maskin [1986b] is in showing that [[[sigma].sup.N].sub.i=1] [U.sup.i](a), where a = ([a.sup.1],...,[a.sup.N]) is the vector of agents' locations, or pure strategies, and [U.sup.i](.)'s are individual utilities as functions of locations, is upper semicontinuous in its arguments.
This remark studies Tibiletti's bargaining condition and shows that, for risk neutral
buyers or the default loss are small relative to the buyer's size, there exists a more shortcut bargaining condition.
The remaining individuals are considered risk neutral
. These division values are arbitrary.
We assume that the insurance market is competitive, and the insurance companies are risk neutral
. However, risk-neutral insurers might act as if they were risk averse.
With risk neutral
firms and risk-averse workers, the presence of moral hazard in search behavior will induce contracts in which the firm bears some but not all of the risk of uncertain unemployment spell duration.
Risk aversion does not completely explain the corporate demand for insurance, since firms can be considered less risk averse or risk neutral
. Researchers find that efficient risk sharing, real-service provision, and resolving agency problems are important reasons for the corporate demand for insurance.
Thus, in the discussion of Arrow-Debreu Static Model, the authors sneak in the concept of risk neutral
where [??] denotes the expectation under the risk neutral
probability measure [??].
Eeckhoudt evaluates the decision tree in the case of a risk neutral
decision maker to obtain a threshold for treatment.
This is the reason why [lambda] is called a Risk Neutral
Probability Measure, and Theorem 1 shows that its existence (and positiveness) is the necessary and sufficient condition to guarantee the absence of arbitrage of the second type (of any kind).
Therefore, the least risk-averse individual in the DEU framework plays the same role as a risk neutral
individual in the expected utility framework.
Although this exercise price is unknown as of the current date, this type of option can be valued using the "risk neutral
" technique of Cox and Ross (1976), a technique that Hatoson and Kreps (1979) generalized into "martingale pricing" theory.
