This paper analyzes the relationship between spatial mobility and social mobility. It develops a two-skill-type spatial equilibrium model of two regions with location preferences where each region consists of an urban area which is home to workplaces and residences and an exclusively residential...

Product bundling may benefit or harm consumers dependingon the correlation betweenconsumer willingness to pay for the bundledgoods and the levels of market dominance of firms. We develop astructural demand model that allows for correlatedconsumer's willingness to pay and flexible...

Internet of Things (IoT) is generally understood to be a realisation of the vision of ubiquitous computing, wherein any type of device will be connected to the Internet and will be controlled by remote software. The transition of Information and Communication Technology (ICT) ecosystem towards...

In 2000, there were as many countries served by a single mobile network as by network competition. Today, only 30 countries, representing less than 3% of the world’s population, are served by a single network. There has been considerable discussion about the optimal number of network operators...

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...

In this paper, we design a theoretical model to analyze the impact of the number of firms on investment in the wireless communications industry. Our model extends the Salop's framework by introducing investment in quality that either reduces the marginal cost of production or shifts the...

Network sharing agreements have become increasingly widespread in mobile telecommunications markets. They carry undeniable advantages to operators and consumers alike, but also the potential for consumer harm. Not all NSAs are created equal: the assessment of the balance of harm and benefits to...

It is a highly controversial topic, both in the regulatory as well as the scientific research environment, whether the beta factor - as a measure for systematic risk - for fixed line and that for mobile operations has actually the same value. Since most telecommunications operators are today...

The optimal market structure in the mobile industry is an important topic in the mobile industry. In this paper, we use two theoretical frameworks and a structural estimation approach to assess the effects of market structure on consumer surplus in symmetric mobile markets. When mobile services...
