Increasingly, buyers are turning to the use of online, reverse auctions in their negotiation activities with suppliers. How does the use of these price competition mechanisms impact buyer-supplier relationships? We consider this question in the context of a quasi-experiment involving six reverse auctions conducted in the supply base of a major industrial buyer. The results indicate that online,...

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.

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...
