In this paper we give a constructive proof of existence of competitive equilibrium in two-sided matching markets. The same approach shows that the set of equilibrium prices is pathwise connected. We then extract from these results an algorithm for finding equilibria which can be further specified to compute the minimum price equilibrium that is optimal for all buyers individually. The two-sided...

Development of obsessive-compulsive symptoms during clozapine treatment in schizophrenics has been noted in few reports from west. In our cases, three schizophrenic patients resistant to typical antipsychotics developed obsessive-compulsive symptoms during clozapine treatment. Since clozapine is a potent 5-HT(2) receptor blocker, role of serotonergic systems in the development of obsessive-comp...

Three experiments investigated the relations between buyers’ wealth or ability to pay (ATP) and sellers’ first offers. Study 1 demonstrated a positive correlation between sellers’ first offers and their perceptions of the buyer’s ATP as well as its real economic power (indicated by the company’s market value). In Study 2, sellers in a field experiment made higher offers to potential buyers of h...

In this work, we study multiple item auctions in a setting where items are distinguished by their relative values; any pair of items have the same ratio of values to all buyers. Buyers have additive valuations for multiple items. The application we have in mind is that items are positions in an ad auction, and an item’s value corresponds to its click-through rate. Buyers have various per-click ...

In this paper, we examine the application of electronic marketplaces, populated by buying and selling agents representing their human users, learning about potential business partners and making recommendations to their users. We propose a novel incentive mechanism to address the unfair rating problem arising when modeling the trustworthiness of selling agents relies on propagation of ratings p...

Data is increasingly being purchased online in data markets and REST APIs have emerged as a favored method to acquire such data. Typically, sellers charge buyers based on how much data they purchase. In many scenarios, buyers need to make repeated calls to the seller’s API. The challenge is then for buyers to keep track of the data they purchase and avoid purchasing the same data twice. In this...

Consumer-to-Consumer (C2C) e-marketplaces cannot survive without participations from both a large number of buyers and sellers. Prior research on trust in e-commerce is mainly conducted from the buyers’ perspective. Combined with TAM constructs, this research explores the relative impacts of trust in terms of trust in market-maker and institution-based trust, and risk on individual’s transactio...
