Consider a situation where there is a cost that is
either incurred or not. It is incurred only if the value
of some random input is less than a specified cutoff
value. Why might a simulation of this situation give a
very different average value of the cost incurred than
a deterministic model that treats the random input as
fixed at its mean? What does this have to do with the
“flaw of averages”?

Solutions

Expert Solution

Here as the situation says that cost may have incurred or not. In economics, the event is not definite and hence we take out its payoff via considering its average outcome out if its probability.

Suppose for example that we know that a fair unbiased coin has the 50-50 chance of head and tail respectively. But on a random day while tossing a coin for 10 times, 9 out of 10 times it was head. That means the average was false. This is called the flaw of average where we take an average while conducting any sampling.

This error could be solved it the experiment is conducted for infinite no of times then the occurrence of head and tail will normalize. This will also do away with the flaw of averages.

In the above case, simulation has given the different average values as the samples were not sufficient to reach a mean. Hence it was suffering from the flaw of average and had an error value. In econometrics denote it as error value and consider it for the more appropriate results.

Consider the following situation: Two animals are competing for territory. Each animal chooses to be either Aggressive or Passive in this competition, and has the following preferences over the outcomes: Each animal would prefer to be Aggressive if the other is Passive: this way they win the competition and gain territory. Each animal would prefer to be Passive if the other is Aggressive: this way they lose territory, but they avoid a fight which would leave them injured. Regardless of...

Consider the situation below where two players are engaged in a game of chicken. In this game, both players drive their cars at each other and each player can choose to either drive straight, or swerve. If both cars drive straight, they will crash in to one another, causing damage to both vehicles. If one car goes straight, while the other swerves, the player that swerves is a "chicken" while the other player is respected for their bravery. If both...

Consider a situation where a company will earn $100 payable in one year if it completes a contract. If the company completes the contract the debt holders are promised a payment of $40 in one year. However, if the firm cannot complete the contract, expected earnings in one year will be only $50. If this results then the bond holders will only receive a payment of $15 (because of the costs of bankruptcy). The probability of the firm completing the...
