We demonstrate a negative relationship between pro-market reforms and the sustainability of superior profits in an emerging economy. The decline in sustainability of superior profits shows that pro-market reforms bring significant threats in addition to the various opportunities such as greater availability of production factors and greater freedom to enter and operate businesses highlighted in...

This paper investigates the effect of capacity constraints on the sustainability of collusion in markets subject to cyclical demand fluctuations. In the absence of capacity constraints (i.e. a limiting case of our model), Haltiwanger and Harrington (1991) show that firms find it more difficult to collude during periods of decreasing demand. We find that this prediction can be overturned if firm...

In our model, two profit-maximizing sellers sell a homogeneous good to Bayesian, riskneutral buyers in an online comparison shopping service. Buyers use a reputation system to update their beliefs about sellers. Buyers purchase from the seller that maximizes the buyer’s expected utility from the purchase. We find that the seller’s profit depends on the distribution of buyer beliefs. A degenerat...

Direct marketing is one of the most effective marketing methods with an aim to maximize the customer's lifetime value. Many cost-sensitive learning methods which identify valuable customers to maximize expected profit have been proposed. However, current cost-sensitive methods for profit maximization do not identify how to control the defection probability while maximizing total profits over th...

We study the effects of bidder collaboration in all-pay auctions. We analyse both mergers, where the remaining players are aware of the agreement between the cooperating participants, and collusion, where the remaining players are unaware of this agreement. We examine two scenarios: the sum-profit model where the auctioneer obtains the sum of all submitted bids, and the max-profit model of crow...

In this paper, we investigate the effectiveness of different types of bidding behaviour for trading agents in the Continuous Double Auction (CDA). Specifically, we consider behavioural types that are neutral (expected profit maximising), passive (targeting a higher profit than neutral) and aggressive (trading off profit for a better chance of transacting). For these types, we employ an evolutio...

one effective method for improving the performance of supply chain is making coordination among members of supply chain. this paper studies the subject of coordination of supply chain by using an insurance contract. the supply chain consists of one-manufacturer and one-retailer that the retailer is faced with potential demand and returning of goods from customer. acceptance of goods returned is...

in this study, a new stochastic model is proposed to deal with a multi-product, multi-period, multi-stage, multi-site production and transportation supply chain planning problem under demand uncertainty. a two-stage stochastic linear programming approach is used to maximize the expected profit. decisions such as the production amount, the inventory level of finished and semi-finished product, t...
