4. Benchmark: First-Best Under Complete Information
Given the vendor type τ, the first-best outcome is obtained by solving the optimization problem.

3.5 Signaling Game We assume that the vendor, who possesses private information about the reliability of a newly developed product, chooses contract terms and proposes them to the buyer. The buyer then accepts the contract terms if his expected payoff exceeds an outside option valued at θ.

3.3 Information Structure We assume that the product offered by the vendor is one of two possible types, L or H, where L denotes low reliability and H denotes high reliability. Hazard rate ordering（危险率序）:

The value of α set by the vendor in her contract may relay information about whether or not the product is reliable.

5.1 Resource-Based Contract
In summary, successful signaling by the reliable vendor is possible under RBC when her inventory choice is verifiable, but it comes at a cost since the vendor has to leave positive surplus to the buyer.

5. Signaling with Verifiable Inventory
We now consider the setting in which the vendor possesses private information about product reliability. 5.1 Resource-Based Contract
