A recent proof of NP-hardness of Euclidean sum-of-squares clustering, due to Drineas et al., <i>Machine Learning</i> 56, 9--33, 2004, is not valid. An altern...

Horizontal cooperation among franchisees is now a well-known reality in franchising, as exemplified by the growing number of franchisee associations and adve...

We consider a duopolistic industry where the current sales of each firm is proportional to its goodwill stock. The evolution of the latter depends positivel...

Minimum sum-of-squares clustering consists in partitioning a given set of <i>n</i> points into <i>c</i> clusters in order to minimize the sum of squared dist...

The aim of this paper is to characterize cooperative and noncooperative advertising strategies of a licensor and licensee involved in a licensing contract ...

A weighted multivariate signed-rank test is introduced for an analysis of multivariate clustered data. Observations in different clusters may then get diffe...

In this paper, we propose a tree-based method for multivariate outcomes consisting in a mixture of categorical and continuous responses. The split function...

This paper attempts to shed an empirical light on so-called jump bidding in ascending auctions. There is a jump when a participant in an auction outbids t...

In this paper, we consider the nonparametric Behrens-Fisher problem with cluster correlated data. A class of weighted Mann-Whitney test statistics are intr...

This study examines simultaneously the effect of personal, contextual, and product-related factors on purchasing behaviour of fair-trade products. The resu...

We identify the conditions under which a myopic pricing behavior could be a profit enhancing tool in the distribution channel. A channel member behaves myo...

<p>The paper determines optimal pricing and advertising policies for an entertainment event, taking into account diffusion effects and a last-minute market...

To the best of our knowledge, the complexity of minimum sum-of-squares clustering is unknown. Yet, it has often been stated that this problem is NP-hard. We...

In an Advance Booking Discount Program (ABDP), a firm offers a product at a price discount prior to the selling season. In the selling season the product i...

We consider a noncooperative differential game where a retailer sells her own private label in addition to the manufacturer’s brand. We assume that each bran...

In this paper, we consider the problem of constructing confidence intervals for a population median when the underlying population is discrete. We describe ...

In this paper, we consider testing the location parameter with multilevel (or hierarchical) data. A general family of weighted test statistics are introduced...

We consider a marketing channel where a retailer sells, along the manufacturer’s brand, her own private label. We assume that each player invests in adverti...

We propose a game-theoretic model involving the manufacturer of a national brand and a retailer selling her private label along with the national brand. The...

<p>The paper considers a problem of how to minimize advertising costs to sell seats for a particular event, for instance, a sports game, a rock concert or a...
