For the two retailers, they face different demand and are both risk averse. We study a single period model which the supplier has ample goods and the retailers order goods separately. Market search is measured as the fraction of customers who unsatisfied with their ＂local＂ retailer due to stock-out, and search for the goods at the other retailer before leaving the system. We investigate how the retailers game for order quantity in a Conditional Value-at-Risk framework and study how risk averse degree, market search level, holding cost and backorder cost influence the optimal order strategies. Furthermore, we use uniform distribution to illustrate these results and obtain Nash equilibrium of order strategies.展开更多

Guangzhou is used as a case study to model the intensity and duration of the search process. This study finds that buyers make trade-off between two search costs, activity cost and duration cost. The study also demonstrates that despite the industry＇s immature nature, buyers using brokers do increase search intensity and shorten search duration by reducing the activity cost. Empirical results show that there is no specific buyer group who can effectively lower their search cost by their own efforts, due to the poor information transparency in the current housing market. The broker-choice model shows that besides search cost, buyers＇ confidence in broker＇s service quality can also greatly influence their choice, so improvement in service quality and reputation has important implications for China＇s brokerage industry.展开更多
