We consider a firm buying a commodity from a spot market as raw material and selling a final product by submitting bids. Bidding opportunities (i.e., demand arrivals) are random, and the likelihood of winning bids (i.e., selling the product) depends on the bid price. The price of the commodity raw material is also stochastic. The objective of the firm is to jointly decide on the procurement and...

A major trend in mobile advertising is the emergence of real time bidding (RTB) based marketplaces on the supply side and the corresponding programmatic impression buying on the demand side. In order to acquire the most relevant audience impression at the lowest cost, a demand side player has to accurately estimate the win rate and winning price in the auction, and incorporate that knowledge in...

Game theoretic approaches to the study of electricity markets have been explored for decades [2], [7], [10]. Recently problems associated with variations of the optimal power flow problem with static (inelastic) demand for an electrical power grid [5], [21], [22], have been considered by several authors, e.g., [15], [17]. Indeed, demand elasticity for electricity is motivated by the onset of po...

We study an optimal bidding and allocation problem that builds upon the earlier work of [4]. The model we is interest in online real-time advertising where demand a large number advertisers aggregated by intermediary who bids auction market on their behalf. This referred to as Demand Side Platform (DSP).

demand response (dr) has many beneficiaries in the electricity market. there are independent players who are interested in dr, which include: transmission system owners, distributors, retailers, and aggregators. in this paper dr is introduced as a tradable commodity that can be exchanged between dr buyers and sellers in a pool-based market which is called demand response exchange (drx). drx ope...

Retailers are increasingly exploiting sequential online auctions as an effective and low cost distribution channel for disposing large quantities of inventory. In such auction environments, bidders have the opportunity of participating in many auctions to learn and choose the bidding strategy that best fits their preferences. Previous studies have mostly focused on identifying bidding strategie...

Agents and market mechanisms are widely elaborated and applied to automate interaction and decision processes among others in robotics, for decentralized control in sensor networks and by algorithmic traders in financial markets. Currently there is a high demand of efficient mechanisms for the provisioning, usage and allocation of distributed services in the Cloud. Such mechanisms and processes...

We analyze the realistic, popular format of an ascending auction with anonymous itemprices, when there are two items that are substitutes. This auction format entails increased opportunities for bidders to coordinate bids, as the bidding process is longer, and since bidders see the other bids and can respond to various signaling. This has happened in many real auctions, e.g., in the Netherlands...
