Suppose you can place a bet in the following game. You flip a fair coin (50-50 chance it lands heads). If it lands heads, you get 4 dollars, if it lands tails, you pay 1 dollar. This is the only bet you can make. If you don't make the bet you will neither gain nor lose money. What is the expected utility of not placing the bet?

Homework Answers

Answer #1

To get the expected utility we will use the normal expectation calculation formula,

which is  

Here we have the values of X is 4 and -1, 4 when we won 4 dollars if it lands on head and -1 when we lose 1 dollar when tail comes, Probability of getting head and tail is 0.5, as it is equally probable.

Now, Expected value of Placing a bet.

Expected Utility when not playing a Bet is 0, because we are neither getting anything nor losing.

Suppose you can take a bet that pays you based on a coin flip.  If the coin ends on heads you receive nothing, if the coin ends on tales you win $500.  Assume that you are risk averse.  First, describe the concept of Certainty Equivalent Wealth (CEW).  Next, describe how and why your CEW changes if your level of risk aversion were to increase.  Finally, describe how and why your CEW changes if the likelihood of ending on tales is greater than 50%.

Suppose you toss a coin 100 times. Should you expect to get exactly 50 heads? Why or why not? A. Yes, because the number of tosses is even, so if the coin is fair, half of the results should be heads. B. No, because the chance of heads or tails is the same, the chance of any number of heads is the same. C. No, there will be small deviations by chance, but if the coin is fair, the result...
