요약This dissertation consists of three theoretical essays related to the market for information.In Chapter 1, I investigate the problem of designing a revenue‑optimal mechanism to sell information when the buyer seeks to decide whether to take a costly action under uncertainty. I devise a mechanism design model of a revenue‑maximizing seller who sells information about a binary state, "good'' or "bad.'' The buyer seeks to act only when the state is good, and inaction yields no payoff. Under a regularity assumption, the optimal mechanism allocates full information to middle‑cost types while allocating no information to high and low‑cost types.In Chapter 2, I investigate the problem of designing a revenue‑optimal mechanism to sell information regarding a dynamically changing state. Extending the model in Chapter 1, I consider a state that switches from bad to good at a random time and a buyer who seeks to decide when to take a costly action. The revenue‑optimal mechanism allocates full information from the outset to middle‑cost types, gives full information only after a deterministic delay to high‑cost types, and provides information with a stationary error to low‑cost types.In Chapter 3, I investigate the welfare implications of the buyer's ability to observe a contractual arrangement under which sellers share first period purchase history before interacting with the buyer. I build a two‑period model with short‑lived monopolistic sellers and a long‑lived buyer who meets the sellers sequentially. I find that the first seller is always worse off in equilibrium when the buyer cannot observe the contracting outcome because of a ratchet effect, while the second seller is indifferent across observability regimes. The buyer's welfare effect is ambiguous except when demand is very inelastic, in which case the buyer is better off when the contracting outcome is not observable.
