According to static models of industrial organization, a rise in competition decreases prices. In this paper, I test whether this conclusion can be reversed in the mobile telecommunications markets where dynamic efficiency effects might be significant. The empirical test relies on the change in...

We analyze the effects of consumers' limited attention on welfare in a model of horizontal product differentiation. We present a novel approach of modeling limited attention: an attention radius. Each consumer only notices goods that are within her attention radius, i.e., goods that are...

We consider a market with two symmetric firms and two asymmetric consumer groups. Firms send advertising messages which inform consumers about the existence and the price of their product (Butters, 1977). Targeting a specific consumer is imperfect as with some probability the consumer is not...

The firms in this model set non-binding list prices before competing for buyers by non-cooperatively granting discounts. Each firm has an incentive to set a high list price if, for example, the customers anchor their willingness-to-pay on the list price. However, list price competition occurs if...

The empirical analysis of firm growth is a classical field in industrial economics. Insights into the determinants of firm growth are particularly interesting for mature markets. A typical example of a mature market is the lodging industry in high-income countries, characterised by a high degree...

This paper addresses the relationship between productivity in the retail sector and market size. In the paper, the systematic variations between central and non-central retail markets, as well as the systematic variations across different types of retailing activities are investigated. The...
