{"title":"The End or the Means? The Pursuit of Competition in Regulated Telecommunications Markets","authors":"Bronwyn E. Howell","doi":"10.2139/ssrn.1227823","DOIUrl":"https://doi.org/10.2139/ssrn.1227823","url":null,"abstract":"Economic analysis takes as its defining performance benchmark the pursuit of increases in welfare (efficiency). Competition is merely one of a variety of means of achieving the efficiency end especially in industries where the underlying economic circumstances predispose them towards greatest efficiency when competition (in the form of many market participants) is restricted. Typically regulatory intervention in these industries is justified by the imperative to increase efficiency. Competition law and industry-specific regulation provide two competing means of intervention whereby the pursuit of efficiency can be enhanced. The challenge is in determining how to allocate responsibility for governance of industry interaction between these two institutional forms. Whilst competition law can govern interaction in most industries where the underlying economic conditions are sufficiently different industry-specific regulation offers advantages. However its weakness is the risk of capture leading to the subjugation of the efficiency end to the pursuit of other objectives (e.g. competition - the means - as an end in itself). But if the regulatory institution could be bound in some way to pursue an efficiency objective could the risk of capture be averted? By exploring the attempts to prioritise the pursuit of efficiency via both competition law and industry-specific regulation in New Zealand over the past twenty years this paper concludes that such an endeavour is unlikely to be successful in the long run. As politicians ultimately control the rules by which the regulatory responsibilities are allocated and politicians are themselves pose a potential risk of capture for the industry-specific regulatory processes the inability of a government prioritising efficiency objectives to bind its successors to the same objectives means that the efficiency objective is not stable. From the New Zealand experience the outcome could be total subjugation of industry-specific regulation to direct political control and the abandonment of efficiency as a primary regulatory objective. This suggests that imperfect though it may be competition law overseen by a judiciary with greater independence of the political process offers the best chance of enshrining pursuit of efficiency into the governance of industry interaction even in industries normally the focus of industry-specific regulation.","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134333819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst empirical evidence is sparse and at best equivocal in respect of a consistent positive and statistically significant effect a recent study commissioned and published by the OECD does find evidence of such effects. When correcting for omitted variables correlated data and methodological inconsistencies our analysis using the models and data from this report instead support the contention that LLU's contribution to the level of national broadband uptake is materially very small and not statistically significant. Continued advocacy for the policy as a stimulant for broadband uptake on the basis of the OECD-published report is misguided.","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124675096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first examine the efficiency of a given network structure in terms of the maximization of total profits in the industry. We show that the efficient network structure depends on the marginal cost of collaboration. When the marginal cost is low, the complete graph is efficient. However, a high marginal costimplies that the efficient network is sparser and has a core-periphery structure. Next, we examine the evolution of the network structure when the decision on collaborating partners is decentralized. We show the existence of multiple equilibrium structures which are in general inefficient. This is due to (i) the path dependent character of the partner selection process, (ii) the presence of knowledge externalities and (iii) the presence of severance costs involved in link deletion. Finally, we study the properties of the emerging equilibrium networks and we show that they are coherent with the stylized facts of R&D networks.","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130312593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide descriptive results from a large scale survey of two online outlaw communities focussing on Microsoft's XBox. In line with previous findings, we identify two types of participants in outlaw communities - user innovators and adopters. Based on 2,256 responses, we find that users modify their XBox mainly to be able to increase the set of available functions of their XBox. Users are also motivated to modify their XBox for the sake of having fun and to conduct pirate behaviour. Finally, the results from our survey suggest that user innovators are largely intrinsically motivated by fun and the intellectual stimulation of writing code for homebrew software.","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128714022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This happens \"mobilizing creatively\" the chain relationship between best practices and standard of management procedure, innovation and communication of it in a diffuse promotion of human creative resources, by both level individuals and community, realizing the interests of all stakeholders (internal and external ones). In this perspective is important to develop and expand the value of identity as intangible resource of visibility and attractor of the most creative resources from environment (real and virtual, close or far). The strategy of the firm assumes a relational form as able to connect the most creative resources and attracting new ones.
