We derive the optimal selling mechanism for a monopolist who is privately informed about the attributes of a horizontally differentiated good. To do so, we set up an informed principal problem in a Hotelling model where the buyer's preferences are described in terms of a base consumption value...

Despite negative experiences with auctioning off subsidies for renewable energy in some countries, tenders are increasingly used today. We develop a reverse auction which accounts for particularities of intermittent renewable energy sources. Determining the quantity, demanded by the regulator,...

This study analyzes optimal zoning policy in a duopolistic spatial competition framework for both circular and linear spaces. A regulator is introduced in the third stage of the price-location game through a welfare function to model zoning preferences from firms and consumers. An equilibrium...

Zonal pricing with countertrading (a market-based redispatch) gives arbitrage opportunities to the power producers located in the export-constrained nodes. They can increase their profit by increasing the output in the dayahead market and decrease it in the real-time market (the inc-dec game)....

We consider general asset market environments in which agents with quasilinear payoffs are endowed with objects and have demands for other agents' objects. We show that if all agents have a maximum demand of one object and are endowed with at most one object, the VCG transfer of each agent is...

This paper develops a framework for studying repeated matching markets. The model departs from the Gale-Shapley matching model by having a fixed set of long-lived players (firms) match with a new generation of short-lived players (workers) in every period. I define history-dependent and...

We study decentralized task coordination. Tasks are of varying complexity and agents asymmetric: agents capable of completing high-level tasks may also take on tasks originally contracted by lower-level agents, facilitating system-wide cost reductions. We suggest a family of decentralized...

Fees are omnipresent in markets but, with few exceptions, are omitted in economic models-such as Double Auctions-of these markets. Allowing for general fee structures, we show that their impact on incentives and efficiency in large Double Auctions hinges on whether the fees are homogeneous (as,...

The price mechanism is fundamental to economics but difficult to reconcile with incentive compatibility and individual rationality. We introduce a double clock auction for a homogeneous good market with multidimensional private information and multiunit traders that is deficit-free, ex post...

Transaction costs are omnipresent in markets yet are often omitted in economic models. We show that their presence can fundamentally alter incentives and welfare in markets in which the price equates supply and demand. We categorize transaction costs into two types. Asymptotically...
