A special case of Myerson’s classic result describes the revenue-optimal equilibrium when a seller offers a single item to a buyer. We study a natural repeated sales extension of this model: a seller offers to sell a single fresh copy of an item to the same buyer every day via a posted price. The buyer’s value for the item is unknown to the seller but is drawn initially from a publicly known di...

Buyer-seller watermarking protocols allow copyright protection of digital goods. To protect privacy, some of those protocols provide buyers with anonymity. However, anonymous e-commerce protocols pose several disadvantages, like hindering customer management or requiring anonymous payment mechanisms. Additionally, no existing buyer-seller watermarking protocol provides fair exchange. We propose...

In Part III of this paper, we apply the price dynamical model with big buyers and big sellers developed in Part I of this paper to the daily closing data of the top 20 stocks in Hang Seng Index in Hong Kong Stock Exchange. The basic idea is to estimate the strength parameters of the big buyers and the big sellers in the model and make buy/sell decisions based on these parameter estimates. We de...

We employ a novel data set on almost 30,000 trade credit contracts to describe the broad characteristics of the parties that contract together and the key terms of these contracts. Whereas prior work has typically used information on only one side of the buyer-seller transaction, we utilize information on both, allowing for the first analysis of buyer-seller pairs. An equally important distinct...

We examine a platform owner’s optimal two-sided pricing strategy while considering seller-side innovation decisions and price competition. We model the innovation race among sellers in both finite and infinite horizons. In the finite case, we analytically show that the platform’s optimal seller-side access fee fully extracts the sellers’ surplus, and that the optimal buyer-side access fee mitig...

We analyze a simple dynamic durable good oligopoly model where sellers are capacity constrained. Two incumbent sellers and potential entrants choose their capacities at the start of the game. We solve for equilibrium capacity choices and the (necessarily mixed) pricing strategies. In equilibrium, the buyer splits the order with positive probability to preserve competition; thus it is possible t...

Buyer-seller watermarking protocols integrate multimedia watermarking and fingerprinting with cryptography, for copyright protection, piracy tracing, and privacy protection. We propose an efficient buyer-seller watermarking protocol based on dynamic group signatures and additive homomorphism, to provide all the required security properties, namely traceability, anonymity, unlinkability, dispute...

This paper investigates the sequential announcement of domestic emissions caps by governments in a international-based tradable pollution permit market for a transboundary pollutant. We …nd the sequential choice of domestic allocation caps is sub-optimal and depends on how the follower government reacts to the leader government’s choice. Furthermore, the marginal damage and the degree to which ...

The rapid growth of online retail in the last decade has led to widespread use of consumer-generated ratings. This paper theoretically and experimentally identifies influences that drive consumers to rate products and examines how those factors can create distortions in product ratings. By manipulating payoffs and effectively “deactivating” either the buyer or seller side of an artificial labor...

This dissertation studies the effect of customer considerations in stochastic optimization problems in the service industry. The first part looks at problems in the service industry geared towards providing efficient service, i.e., minimizing the total cost of providing service while ensuring that certain service level targets are met. In particular, we study applications in the call center ind...
