Suppose that you want to invest $10,000 for a period of 5 years. After getting financial advice, you come up with the following game matrix, where you (R) are playing against the economy (C). Each entry in the matrix is the expected payoff (in dollars) after 5 years for an investment of $10,000 in the corresponding row designation, with the future state of the economy in the corresponding column designation. (The economy is regarded as a rational player who can make decisions against the investor—in any case, the investor would like to do the best possible, irrespective of what happens to the economy.) Find saddle values and optimal strategies for each player.
