This paper examines the consequences of introducing mobile number portability (MNP). As MNP allows consumers to keep their telephone number when switching providers, it reduces consumers' switching costs. However, MNP may also cause consumer ignorance if telephone numbers no longer identify...

I examine the effects of FCC regulation on the innovation and introduction of advanced telecommunications services in the U.S. An interim of lighter regulation provides an experiment to test the regulatory regime''s impact on innovation. The econometric model comprises an arrival process (for...

Satellite communication is integral to Digital India, enabling ubiquitous broadband for the uncovered population and supporting satellite TV, the dominant source of infotainment. An enabling policy environment would help increase the market share of Indian satellite service providers from the...

This paper endogenizes the interplay between innovation by a regulated firm and regulatory delay. When product innovation costs fall over time, an extra day of regulatory delay increases time to introduction by more than a day. In the signaling model, the firm therefore times its innovation to...

This paper analyses whether scale economies exists in the UK telecommunications industry. The approach employed differs from other UK studies in that panel data for a range of companies is used. This increases the number of observations and thus allows potentially for more robust tests for...

A striking pattern in transaction-level data is the concentration of international shipments in the hands of a few large firms. One common feature of dominating high-performance firms is that they produce multiple products and ship them to many destinations. Motivated by the emergence of highly...

In this paper I investigate the impact of a decrease in trade costs on firms' decisions to export. The main contribution of this paper is to evaluate empirically the theoretical predictions of several models of multi-product exporters. The focus is on the firm export entry decision and the...

This paper investigates whether firms' exports of different products within a market are systematically interconnected. Using high-quality Swedish firm-registry data from 1997-2011, I first document that the distribution of firm export sales is skewed towards their best performing products...
