Collaboration and competition in presence of imperfect information and non-linear pricing

Karabaş, Şükriye
In this thesis, a market is assumed with n competing buyers where price is an inverse linear function of the quantity supplied to the market. The buyers get engaged in Cournot competition, but may also collaborate on purchasing decisions from a supplier. The supplier offers a quantity discount, as the quantity purchased increases unit price decreases. Furthermore, the demand base in the market is uncertain, but the buyers may get a signal of the demand. In this setting, the value of collaboration, information sharing and non-linear pricing is analyzed.


Uniform trade rules for uncleared markets
Kibris, Oezguer; Küçükşenel, Serkan (Springer Science and Business Media LLC, 2009-01-01)
We analyze markets in which the price of a traded commodity is such that the supply and the demand are unequal. Under standard assumptions, the agents then have single peaked preferences on their consumption or production choices. For such markets, we propose a class of Uniform trade rules each of which determines the volume of trade as the median of total demand, total supply, and an exogenous constant. Then these rules allocate this volume "uniformly" on either side of the market. We evaluate these "trade...
Procurement and information sharing games in group purchasing
Ünel, Sevgi; Savaşaneril Tüfekci, Seçil; Department of Industrial Engineering (2014)
In this thesis, the value of collaboration and information sharing is analyzed for a market with two asymmetric competitive buyers. On one side of the chain, the supplier offers quantity discount. On the other side of the chain, the buyers may or may not engage in collaboration on purchasing quantity. The price is inverse linear function of the quantity supplied in the market. Buyers may receive a signal about uncertain market demand. Each buyer decides whether to share the signal with the other buyer and t...
Local volatility model applied to BIST30 european warrants: pricing and hedging
Kirazoğlu, Zekiye Sıla; Sezer, Ali Devin; Department of Financial Mathematics (2016)
One of the basic observations on pricing options is that the assumption of constant volatility does not agree with data and market price data gives a volatility smile that depends on maturities and strike prices. The first model that developed to be compatible with this observation is the local volatility model. The purpose of this work is to study the performance of the local volatility model on BIST30 warrants and compare it to the standard Black Scholes model. To estimate the local volatility model from d...
Supply function equilibria for uniform price auction in oligopolistic markets
Vasin, Alexander; Dolmatova, Marina; Weber, Gerhard Wilhelm (2016-12-01)
We consider game-theoretic models related to the supply function auction for electricity markets. We determine the set of supply function equilibria (SFE), introduced by Klemperer and Mayer (Econometrica 57:1243-1277, 1989), for a symmetric oligopoly with linear demand, fixed marginal cost and capacity constraint. This set depends on the maximum random shock of the demand function. We also study the best response dynamics and show that in general it does not converge to any SFE. We find out sufficient condi...
Uniqueness of the reserve price with asymmetric bidders
Günay, Hikmet; Meng, Xin; Nagelberg, Mark (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2016-8)
We analyze the optimal reserve price in a second price auction when there are 𝑁 types of bidders whose valuations are drawn from different distribution functions. The seller cannot determine the specific “distribution type” of each bidder. In this paper, we give sufficient conditions for the uniqueness of the optimal reserve price. Then, we give sufficient conditions that ensure the seller will not use a reserve price; hence, the auction will be efficient.
