In this presentation, we consider a duopoly where retailers compete by providing inventory under the circumstances where unsatisfied customers may seek satisfaction elsewhere or leave. A very general framework is formulated to address a variety of customer avenues when stock is unavailable. We find a base-stock inventory policy is the equilibrium policy in the infinite horizon (open loop) under several mild conditions; this model's solution is known as an equilibrium in stationary strategies (ESS). We consequently determine conditions under which the parsimonious base-stock policy is the Markov equilibrium (closed loop) in a discrete-time dynamic game for a general time horizon, coinciding with the ESS base-stock levels. Importantly, when these conditions do not apply, we have counterexamples where a firm has a unilateral incentive to deviate from the ESS, stocking at a higher level. These examples demonstrate a value of inventory commitment, where the retailer may extract a benefit over multiple periods through committing to a higher stocking level and forcing her rival to understock. Our conclusion is that when the Markov solution is base-stock, it coincides with the ESS, but other Markov solutions also exist.","PeriodicalId":142982,"journal":{"name":"Behavioral and Quantitative Game Theory","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132519087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, \"old\" products based on sustaining technology are perceived to be superior to the \"new\" ones based on disruptive technology. However, the latter have distinctive features that allow them to attract an exclusive set of customers. Examples include notebooks vs. netbooks, hard-disk drives vs. solid-state drives, laser printers vs. inkjet printers, etc. We set up a model with an established firm and an entrant firm that have heterogeneous product-offering capabilities: the established firm can offer either or both types of products, while the entrant firm can only offer the new products. Firms make capacity, pricing, and quantity decisions that maximize their ex-ante profit. Within this framework, we analyze deterministic games with perfect information and stochastic games with uncertain valuation of the disruptive technology. Equilibriums decisions are discussed under various market conditions as well as dedicated vs. flexible capacity assumptions. While over-investment and over-production may occur in a stochastic game with dedicated capacities, the equilibrium capacity decision seems to be more rational if the establish firm utilizes flexibly capacity or if the dedicated capacity can be converted ex-post at some expense.","PeriodicalId":142982,"journal":{"name":"Behavioral and Quantitative Game Theory","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131880299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the dictator/ultimatum choice game, the proposer first selects whether or not the receiver will have the power to reject the offer. Effectively, the proposer decides between playing a dictator and an ultimatum game. Whether a player is self-regarding or motivated by distributive concerns, the player should elect the dictator game as it enables full control over the allocation. Yet, a majority of subjects select the ultimatum game. Further, even those selecting the dictator game make substantially higher offers than those in a control dictator experiment. Additional experiments and surveys explore various explanations for these results. The additional experiments suggest that players' willingness to share decision-making power with other players is quite robust. I conclude that subjects have an innate preference for \"voice,\" a key component of procedural justice.","PeriodicalId":142982,"journal":{"name":"Behavioral and Quantitative Game Theory","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125776207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
