We derive optimal bidding strategies for a global bidder who participates in multiple, simultaneous second-price auctions with perfect substitutes. We first consider a model where all other bidders are local and participate in a single auction. For this case, we prove, somewhat surprisingly, that the global bidder should always place non-zero bids in all available auctions, irrespective of the ...

The key difference between objective based multi-asset investing and traditional multi-asset investing is that the objective based portfolio is not anchored to a single strategic asset allocation (SAA) based on long run assumptions. The application of a long run SAA portfolio is convenient since it provides a basis for anchoring the investment strategy and therefore also provides a performance ...

This study investigates when individuals from advantaged and disadvantaged groups are in favor of reducing income inequality. Using a model that considers both an individual’s absolute income and relative income, I examine the conditions under which income equalization is supported by some members in the advantaged group and, more interestingly, opposed by part of the disadvantaged group. In eq...

The existing literature has given little consideration to social values of information technology in general or of wireless technology in particular. The purpose of this paper is therefore to shed new light on this issue. Based on an interpretive case study, we examine two healthcare organisations and discover that social values are often manifested beyond, as well as within, organisations. A m...

In this paper, we consider a two-retailer and one-supplier supply chain in which retailers make an extra effort to satisfy demand from customers who experience stockouts — retailers offer to direct-ship out-of-stock items on an expedited basis at no extra cost to customers. This practice is referred to as the fast-ship option. By supporting the fast-ship option, retailers and suppliers can redu...

Collusion between suppliers in reverse auctions may damage buyers’ benifits and then lower efficiency of resource allocation. Under first-price sealed-bid reverse auction mechanism, suppliers' equilibrium bidding strategy and buyers' revenue loss was analyzed considering collusion. Then some general conclusions were given: suppliers' bidding strategy is relevant to some factors such as valuatio...

IT strategic alignment remains a key concern for business executives over decades. Unfortunately, prior empirical studies tend to ignore the relevance of cultural and capability dimensions to IT strategic alignment. Consequently, whether IT-related orientation and capabilities are adequate for attaining organizational goals and leading to business values still requires exploration. This study a...

This paper studies the model identification problem of k-double auctions between one buyer and one seller when the transaction price, rather than the traders’ bids, can be observed. Given only the price data is available, I explore an identification strategy that utilizes the double auctions with extreme pricing weight (k = 1 or 0) and exclusive covariates that shift only one trader’s value dis...

In today’s increasingly competitive business environment companies can, and indeed must, respond more rapidly to customers’ changing demands, desires, and preferences. In today’s information-rich environment customers can comparison shop, get product reviews from other customers, and, in general, become very well informed about what is available in the market. • If your offerings are not differ...
