Ana and Dina are considering contributing toward the creation of a public park. Each can choose whether to contribute $400 to the public park or to keep that $400 for a cell phone. Since a public park is a public good, both Ana and Dina will benefit from any contributions made by the other person. Specifically, every dollar that either one of them contributes will bring each of them $0.80 of benefit. For example, if both Ana and Dina choose to contribute, then a total of $800 would be contributed to the public park. So, Ana and Dina would each receive $640 of benefit from the public park, and their combined benefit would be $1,280. This is shown in the upper left cell of the first table. Since a cell phone is a private good, if Ana chooses to spend $400 on a cell phone, Ana would get $400 of benefit from the cell phone and Dina wouldn't receive any benefit from Ana's choice. If Ana still spends $400 on a cell phone and Dina chooses to contribute $400 to the public park, Ana would still receive the $320 of benefit from Dina's generosity. In other words, if Ana decides to keep the $400 for a cell phone and Dina decides to contribute the $400 to the public project, then Ana would receive a total benefit of $400 + $320 = $720, Dina would receive a total benefit of $320, and their combined benefit would be $1,040. This is shown in the lower left cell of the first table. Complete the following table, which shows the combined benefits of Ana and Dina as previously described. Dina Contributes Doesn't contribute Contributes $1,280 $ Ana Doesn't contribute $1,040Of the four cells of the table, which gives the greatest combined benefits to Ana and Dina? O When Ana contributes to the public park and Dina doesn't, or vice versa When neither Ana nor Dina contributes to the public park When both Ana and Dina contribute to the public park Now, consider the incentive facing Ana individually. The following table looks similar to the previous one, but this time, it is partially completed with the individual benefit data for Ana. As shown previously, if both Ana and Dina contribute to a public good, Ana receives a benefit of $640. On the other hand, if Dina contributes to the public park and Ana does not, Ana receives a benefit of $720. Complete the right-hand column of the following table, which shows the individual benefits of Ana. Hint: You are not required to consider the benefit of Dina. Dina Contribute Doesn't contribute Contribute $640, -- $ Ana Doesn't contribute $720, -If Dina decides to contribute to the public park, Ana would maximize her benefit by choosing to the public park. On the other hand, if Dina decides not to contribute to the public park, Ana would maximize her benefit by to the public park. not to contribute These results illustrate to contribute
