12. Explain the aggregation effect and the team diversity effect in the context of shared information goods. What is the implication of a market where the team diversity effect dominates the aggregation effect? 13. The table below shows the payoff matrix in a game in which two firms must choose whether or not to innovate and enter a market. Both firms costlessly hold a share in the patent associated with any innovation that takes place (regardless of whether or not they create that innovation). If both enter and innovate they each earn a payoff of r-c where r is a firm's revenues and c are the firm's costs of entry. If neither enters/innovates, each firm receives a zero payoff. In the event that one firm enters/innovates and the other does not, the firm who enters receives a high revenue payoff R>r but must pay a portion of these revenues () to the other firm in addition to entry costs. Firm 2 Enter/innovate Don't enter/innovate Enter/Innovate -C,- (1-OR-C, OR Firm 1 Don't enter/innovate OR, (1-OR-C 0,0 a) Under what circumstances will the existence of the patent in this game result in no innovation taking place? b) Under what circumstances does a patent system have no impact on firms' decisions to innovate
