The framework considers the productive allocative and dynamic efficiency effects of each regime and the nature of the strategic interaction of sector participants. The analysis reveals that substantial gains in all forms of efficiency were achieved during the 1990s both compared to historic New Zealand and contemporary OECD benchmarks. Under industry-specific regulation however transfers to consumers appear to have reduced transaction costs have increased and delays are being incurred in the deployment of new applications and technologies relative to the competition law regime as participants engage in strategic gaming with politicians and the regulator and respond predictably to the range of incentives offered under the regulatory regime. The paper concludes that on balance in the New Zealand circumstances the regime based predominantly upon competition law appears to have outperformed the industry-specific regulatory regime albeit due in large part to sector participant interaction shaped by contractual obligations imposed by the government on the incumbent which have prevailed unchanged under both regimes.pdfen-NZPermission to publish research outputs of the New Zealand Institute for the Study of Competition and Regulation has been granted to the Victoria University of Wellington Library.
