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 study empirically examines a sample of national wireless spectrum assignments for the period 2000-2007 to identify the sources of revenue variations. An econometric model that recognises the censored nature of the sample relates per capita winning bid (per Mhz) values to auction design...

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...
