We empirically test the hypothesis that the discounts offered by firms to consumers who purchase tickets in advance increase with the intensity of competition. We develop a new measure of competition for which we use the proximity (in departure time) of a given flight to its competitors to infer...

This paper examines the effect of counterfeit goods in a world where consumers are differentiated by level of income and innovation is quality enhancing. Counterfeit goods are defined as products with the same characteristics as originals, but of lower quality. The effect of imitation on firms`...

Our underlying hypothesis is that technological progress (even neutral) has a big effect on distribution, not only on growth, since rising waves of technical progress cause rising monopoly power. We test it by showing that, since the 1970's, information technology (in short IT) has caused rising...

From the perspective of an existing retailer, the optimal size of a cluster of retail activity represents a trade-off between the marginal increases in consumer attraction from another store against the depletion of the customer base caused by an additional competitor. We estimate opening and...

Data-driven AI pricing algorithms in on-line markets collect consumer information and use it in their pricing technologies. In the simplest symmetric Hotelling's model such technologies reduce prices and profits. We extend Hotelling's model with vertically diferentiated products, cost...

Here we reproduce the table of contents and the introductory chapter to our book of related essays published by Edward Elgar. These essays deal with the important implications of allowing for the distribution of goods in characteristic space and of producers in geographic space. Although several...

Some legal academics have claimed that ‘machine collusion’ – tacit collusion generated by self-learning pricing algorithms without human involvement - is a real threat that will go uncheck by current antitrust. Half a decade after these claims received wide publicity the only evidence are...

Data-driven AI pricing algorithms in on-line markets collect consumer information and use it in their pricing technologies. In the simplest symmetric Hotelling's model such technologies reduce prices and profits. We extend Hotelling's model with vertically differentiated products, cost...

Market manipulation is a poorly understood phenomenon, due in part to legal standards that categorize manipulative behavior as either an act of outright fraud or as the nebulous use of market power to produce an artificial price. In this paper, we consider a third type of behavior that can...
