# Expected Value Theory

## Expected Value Theory Cumulative prospect theory and the St.Petersburg paradox

The paradox arises by the fact that no rational human would risk a large finite amount to play the game, even though the. For this example, the expected utility of Investment A is greater than that for Investment [ ] B. Even though the expected value of Investment B is greater. The allocation signal is compared with an expected value. Basic concepts of probability theory such as distribution, expectation value, standard deviation. The main concepts of risk aversion theory are defined in terms of probabilistic indicators (expected value, variance, covariance, etc.). This chapter concerns a. Utility theory or, value theory in general, is certainly the cornerstone of decision theory, game theory, microecon~mics, and all social and political theories which​. For this example, the expected utility of Investment A is greater than that for Investment [ ] B. Even though the expected value of Investment B is greater. The main concepts of risk aversion theory are defined in terms of probabilistic indicators (expected value, variance, covariance, etc.). This chapter concerns a.

Credibility theory introduced by B. Preis für Deutschland Brutto. The expected value of the cost of repairs is:. Registrieren Einloggen. The risk is a phenomenon that appears in almost all economic and financial activities e.

Why 8 and not 10? This means that over the long run, you should expect to lose on average about 33 cents each time you play this game.

Yes, you will win sometimes. But you will lose more often. Now suppose that the carnival game has been modified slightly. In the long run, you won't lose any money, but you won't win any.

Don't expect to see a game with these numbers at your local carnival. If in the long run, you won't lose any money, then the carnival won't make any.

Now turn to the casino. In the same way as before we can calculate the expected value of games of chance such as roulette. In the U. Half of the are red, half are black.

Both 0 and 00 are green. A ball randomly lands in one of the slots, and bets are placed on where the ball will land.

One of the simplest bets is to wager on red. If the ball lands on a black or green space in the wheel, then you win nothing.

What is the expected value on a bet such as this? Here the house has a slight edge as with all casino games.

As another example, consider a lottery. This gives us an expected value of:. So if you were to play the lottery over and over, in the long run, you lose about 92 cents — almost all of your ticket price — each time you play.

Related Terms Random Variable A random variable is a variable whose value is unknown, or a function that assigns values to each of an experiment's outcomes.

How Binomial Distribution Works The binomial distribution is a probability distribution that summarizes the likelihood that a value will take one of two independent values.

Uniform Distribution Definition In statistics, uniform distribution is a type of probability distribution in which all outcomes are equally likely.

What Joint Probability Tells Us Joint probability is a statistical measure that calculates the likelihood of two events occurring together and at the same point in time.

Joint probability is the probability of event Y occurring at the same time that event X occurs. Bayes' Theorem Bayes' theorem is a mathematical formula for determining conditional probability.

How Discrete Distribution Works A discrete distribution is a statistical distribution that shows the probabilities of outcomes with finite values.

Scenario analysis is one technique for calculating the expected value EV of an investment opportunity. It uses estimated probabilities with multivariate models to examine possible outcomes for a proposed investment.

Scenario analysis also helps investors determine whether they are taking on an appropriate level of risk given the likely outcome of the investment.

The EV of a random variable gives a measure of the center of the distribution of the variable. Essentially, the EV is the long-term average value of the variable.

Because of the law of large numbers , the average value of the variable converges to the EV as the number of repetitions approaches infinity.

The EV is also known as expectation, the mean or the first moment. EV can be calculated for single discrete variables, single continuous variables, multiple discrete variables, and multiple continuous variables.

For continuous variable situations, integrals must be used. To calculate the EV for a single discrete random variable, you must multiply the value of the variable by the probability of that value occurring.

Take, for example, a normal six-sided die. Once you roll the die, it has an equal one-sixth chance of landing on one, two, three, four, five, or six.

Given this information, the calculation is straightforward:. If you were to roll a six-sided die an infinite amount of times, you see the average value equals 3.

If a belief already exists, it can and most likely will be modified by new information. Second, individuals assign a value to each attribute that a belief is based on.

Third, an expectation is created or modified based on the result of a calculation based on beliefs and values.

For example, a student finds out that a professor has a reputation for being humorous. The student assigns a positive value to humor in the classroom, so the student has the expectation that their experience with the professor will be positive.

When the student attends class and finds the professor humorous, the student calculates that it is a good class. Fishbein and Ajzen represented the theory with the following equation where attitudes a are a factorial function of beliefs b and values v.

In the late s and early s, Fishbein and Ajzen expanded expectancy—value theory into the theory of reasoned action TRA.

Both TRA and TPB address predictive and explanatory weaknesses with EVT and are still prominent theories in areas such as health communication research, marketing, and economics.
