Recently fixed pricing and auctions have been brought together in a new pricing format that offers bidders the option of prematurely ending an auction at a fixed price. The growing popularity of auctions presents an interesting pricing decision for managers: whether to sell at a fixed price, in a regular auction, or through a buy-it-now auction. This paper studies eBay’s buy-it-now auction and ...

In the present study, the effects of bioethanolunleaded gasoline blends on engine performance were investigated in a spark ignition engine. Fuel containing 100% ethanol (E100), fuel blend containing 40% bioethanol by volume (E40) and 100% unleaded gasoline (E0) were tested and the test results were compared. As the result of the study, it was found that the use of unleaded gasoline and bioethan...

Our objective is to assess personal income under perfect competition, when factors are rewarded according to their productivities, and to contrast the ensuing distribution with the status quo. Competition will yield winners and losers, both in terms of factor claims and in terms of regions or provinces. Income differences will press people to migrate. To analyze this, we divide China into 30 in...

Until its sales of a product materialize, a firm is a “pre-producer” in the market for that product. That firm may may be a new start-up, or it may already sell other products. Firms that do not succeed in generating sales eventually become discouraged and move on to other activities. When this fate befalls a lot of firms, as it recently did in several IT-related businesses, the indistry experi...

Until recently, cryoprecipitate has been the treatment of choice in patients with severe von Willebrand disease (vWD) because it can transiently correct low plasma levels of factor VIII coagulant activity (FVIII:C) and shorten or normalize the prolonged bleeding time (BT), the two laboratory hallmarks of the disease. However, cryoprecipitate may still transmit blood-borne viruses, whereas the d...

The concentrations of various trace elements and radionuclides have been measured in marine protein concentrates prepared from surface feeding fishes. As with concentrates prepared from benthic fishes, the 210Pb-210Po pair are the most significant radionuclides present. Concentrations of stable Pb, Co and Ag in certain concentrates are sufficiently high to contribute substantially to estimated ...

It is well known that in linear programming, the optimal values of the dual variables can be interpreted as shadow prices (marginal values) of the right-hand-side coefficients. However, this is true only under nondegeneracy assumptions. Since real problems are often degenerate, the output from conventional LP software regarding such marginal information can be misleading. This paper surveys and...
