Computing integral solutions of complementarity problems
Laan, Gerard van der; Talman, Dolf; Yang, Zaifu - 2004
In this paper an algorithm is proposed to find an integral solution of (nonlinear) complementarity problems. The … algorithm starts with a nonnegative integral point and generates a unique sequence of adjacent integral simplices of varying … dimension. Conditions are stated under which the algorithm terminates with a simplex one of whose vertices is an integral …

Approximate results for a generalized secretary problem
Dietz, Chris; Laan, Dinard van der; Ridder, Ad - 2010
A version of the classical secretary problem is studied, in which one is interested in selecting one of the b best out of a group of n differently ranked persons who are presented one by one in a random order. It is assumed that b is bigger than or equal to 1 is a preassigned number. It is...

Electronic commerce and retail channel substitution
Janssen, Maarten C. W.; Noll, Rob van der - 2002
We analyze a market where firms compete in a conventional and an electronicretail channel. Consumers easily compare prices online, but some incur purchaseuncertainties on the online channel. We investigate the market shares of the two retailchannels and the prices that are charged. We find that...

Artificial collusion : examining supracompetitive pricing by Q-learning algorithms
Boer, Arnoud V. den; Meylahn, Janusz M.; Schinkel, … - 2022
We examine recent claims that a particular Q-learning algorithm used by competitors 'autonomously' and systematically … detailed analysis of the inner workings of this algorithm reveals that there is no immediate reason for alarm. We set out what … is needed to demonstrate the existence of a colluding price algorithm that does form a threat to competition. …

Stochastic dominance efficiency analysis of diversified portfolios : classification, comparison and refinements
Lizyayev, Andrey - 2010
For more than three decades, empirical analysis of stochastic dominance was restricted to settings with mutually exclusive choice alternatives. In recent years, a number of methods for testing efficiency of diversified portfolios have emerged, which can be classified into three main categories:...
