Without censorship, the threat of bad news provides strong incentives for investment. I highlight discontinuities in the firm’s maximum equilibrium payoff that censorship creates. When censorship is inexpensive, the firm never invests and a patient firm’s payoffs approach the lowest possible. In contrast, when censorship is moderately expensive, there exist equilibria where product quality is persistently high and payoffs approach the first-best, which can exceed the maximum equilibrium payoff if it was unable to censor.

Search and moral hazard interact in equilibrium. If using transfers to compensate agents failing to contract, the equilibrium allocation is always constrained-welfare-optimal in contrast to the one-to-one principal-agent problem. Search frictions thus correct that inefficiency because search requires internalizing the utility of agents. Incentives are weaker than in bilateral contracting, and agents enjoy more efficient risk sharing. With a constraint on transfers the allocation may become inefficient; principal competition results in overinsurance of the agents, too little effort in equilibrium, and excessive entry by principals.

We find that consumers perceive contracts as differentiated and both limited awareness and switching costs hinder efficient choices. Our counterfactuals reveal substantial welfare gains from alleviating both frictions, in particular switching costs, and that a well-regulated monopoly can generate similar consumer surplus as the current deregulated market.

What about using an auction? This paper studies the introduction of auctions into this market by Ticketmaster in the mid-2000s. By combining primary-market auction data from Ticketmaster with secondary-market resale value data from eBay, we show that Ticketmaster’s auctions “worked”: they substantially improved price discovery, roughly doubled performer revenues, and, on average, nearly eliminated the potential arbitrage profits associated with underpriced tickets. We conclude by discussing why, nevertheless, the auctions failed to take off.

We identify conditions on collective choice rules such that team decisions are stochastically optimal: the probability the team chooses an action is increasing in its equilibrium expected payoff.
