The zero effect is a slight adjustment to the certainty effect that states individuals will appeal to the lottery that doesn't have the possibility of winning nothing (aversion to zero). During prior Allais style tasks that involve two experiments with four lotteries, the only lottery without a possible outcome of zero was the zero-variance ...
He proposed that a nonlinear function of utility of an outcome should be used instead of the expected value of an outcome, accounting for risk aversion, where the risk premium is higher for low-probability events than the difference between the payout level of a particular outcome and its expected value. Bernoulli further proposed that it was ...
The most immediate effect of easy money, if implemented when the economy is below capacity, may be increased economic growth. In addition, the value of securities rises in the short term. If prolonged, the policy affects the business sentiment of firms and can reverse course over fears of rampant inflation.
Most theoretical analyses of risky choices depict each option as a gamble that can yield various outcomes with different probabilities. [2] Widely accepted risk-aversion theories, including Expected Utility Theory (EUT) and Prospect Theory (PT), arrive at risk aversion only indirectly, as a side effect of how outcomes are valued or how probabilities are judged.

This effect was first presented by Kahneman and Tversky as a part of the prospect theory, in the behavioral economics domain. The reflection effect is an identified pattern of opposite preferences between negative as opposed to positive prospects: people tend to avoid risk when the gamble is between gains, and to seek risks when the gamble is ...
[2] Lucas’ paper “Expectations and the Neutrality of Money” expands on Muth's work and sheds light on the relationship between rational expectations and the monetary policy. The paper argues that when individuals hold rational expectations, changes in the money supply do not have real effects on the economy and the neutrality of money holds.

The first states that in economic equilibrium , a set of complete markets , with complete information , and in perfect competition , will be Pareto optimal (in the sense that no further exchange would make one person better off without making another worse off).
