Roommates Voting: Three roommates need to vote on whether they will adopt a new rule and clean their apartment once a week or stick to the current once-a-month rule. Each votes "yes" for the new rule or "no" for the current rule. Players 1 and 2 prefer the new rule while player 3 prefers the old rule.

a. Imagine that the players require a unanimous vote to adopt the new rule. Player 1 votes first, then player 2, and then player 3, the latter two observing the previous votes. Draw this as an extensive-form game and find the Nash equilibria.

b. Imagine now that the players require a majority vote to adopt the new rule (at least two "yes" votes). Again player 1 votes first, then player 2, and then player 3, the latter two observing the previous votes. Draw this as an extensive-form game and find the Nash equilibria.

c. Now imagine that the game is as in part (b), but the players put their votes into a hat-so that the votes of earlier movers are not observed by the later movers-and the votes are counted after all have voted. Draw this as an extensive-form game and find the Nash equilibria. In what way is this result different from the result in (b)?

You are a US senator deciding whether to vote yes or no on new legislation. The potential new law places restrictions on the practice of outsourcing work to low-wage countries and is designed to protect US workers’ jobs. These days it is increasingly common for companies to promise manufacturing contracts to overseas suppliers in exchange for access to that country’s market. Labor union representatives at home argue that these kinds of deals cost jobs as factories close and parts are...

Empty Voting The general principle of one-share-one-vote relies on the view that shareholders with the largest economic interest in the company’s success should have the largest say in any decision. But in recent years there have been an increasing number of instances where the votes controlled by hedge funds or other activist investors have been proportionately much larger than their economic interest in the company. There are several ways that this divergence between control rights and cash-flow rights can occur....

Let’s see whether quadratic voting can avoid the paradox of voting that arose in Table 5.3 when using 1p1v in a series of paired-choice majority votes. To reexamine this situation using quadratic voting, the table below presents the maximum willingness to pay of Garcia, Johnson, and Lee for each of the three public goods. Notice that each person’s numbers for willingness to pay match her or his ordering of preferences (1st choice, 2nd choice, 3rd choice) presented in Table 5.3....
