Equilibria Strategies for Selecting Sellers and Satisfying Buyers

Dynamism of trade activity inevitably results in situations where sellers face local supply shortages. In such cases, sellers need to decide which buyer purchase requests to satisfy. Commonly, sellers satisfy purchase requests based on their arrival order, i.e., First In is First Served (FIFS). In electronic trade, sellers may follow strategies diier-ent from FIFS without the buyers being able to detect this diierence. Buyers, in response to the sellers' strategic behavior, may themselves adopt strategies that will maximize their utility. Previous research has suggested strategies to be used by electronic seller-agents and buyer-agents. Yet, that research examined markets in which buyers are willing to accept partial satisfaction of their request and sellers' stocks are all the same. A simulation tool was developed under such conditions. This paper utilizes the simulation tool to explore equilibria in more realistic markets, where sellers' stocks are heterogeneous, and buyers suuer signiicant losses from partial satisfaction of their requests.
