Title：Coopetition in Linear Production Games

Abstract:

Coopetitive resource sharing, which has experienced a dramatic growth in the last few years with emergence of the sharing economy, is a powerful way of integrating resources, mitigating risks and enhancing performances. This is a game with interaction of two different types of logic, in which strategic players share cooperatively their resources at certain costs and, at the same time, pursue competitively for their own maximum utilities.

We study an organic combination of cooperation and competition in coopetitive resource sharing. We look into different schemes for fair allocation of coalitional benefits in linear production games and how these schemes can generate different equilibria in competition. We identify a particular scheme that dominates other schemes in terms of the quality of their resulting social welfare at equilibrium.

Our research is a first attempt to extend the focal dimension of incentive schemes from whether players would stay in the grand coalition in cooperative game theory to what extent they would cooperate in the grand coalition in a coopetition game.

Title：The Effect of Multi-Channel and Omni-Channel Retailing on Physical Stores

Abstract: Most retailers today sell products through an online channel in addition to traditional physical stores. Customers may find online shopping attractive because it helps them avoid traveling to a store, but they have to incur an online hassle cost due to the inconvenience from having to wait, delivery costs, etc. However, purchasing the product online without being able to inspect it may lead to more returns for the retailer. In contrast, visiting a physical store allows customers to inspect the product before purchasing it, but they also have to incur a travel cost. Given the complex trade-offs associated with customers' purchasing decisions, a natural question is how the online channel influences a retailer's decisions regarding the physical stores. In this paper, we study how a multi-channel or omni-channel retailer should decide the number and size of physical stores. We show that contrary to expectation, as online shopping becomes more convenient, it can be wise for a retailer to open more physical stores that are smaller in size. We also find that a higher product return rate for online purchases can incentivize the retailer to open fewer physical stores that are larger in size. We also study the effect of three popular omni-channel strategies and show that the retailer should have more stores with showrooms (where physical stores only display products for customers to inspect before purchasing online) but fewer stores with either return flexibility (where customers can return their online purchases to a physical store) or in-store pick up (where customers pick up online purchases in a physical store).
