Internet Peering as a Network of Relations

We apply results from recent theoretical work on networks of relations to analyze optimal peering strategies for asymmetric ISPs. It is shown that - from a network of relations perspective – ISPs’ asymmetry in bilateral peering agreements need not be a problem, since when these form a closed network, asymmetries are pooled and information transmission is faster. Both these effects reduce the incentives for opportunism in general, and interconnection quality degradation in particular. We also explain why bilateral monetary transfers between asymmetric ISPs (Bilateral Paid Peering), though potentially good for bilateral peering, may have rather negative effects on the sustainability of the overall peering network

Theory and evidence on pricing by asymmetric oligopolies

We present an analysis of markets with many asymmetrically positioned retailers that compete for the business of both informed and uninformed customers for a homogenous good, such as software, music, book or a brand-name appliance. We show that two forms of asymmetry, one related to loyal segment sizes of retailers and one related to the positioning of firms, completely explain the observed price dispersion in such markets and the multitude of asymmetrical strategies adopted by retailers. The stochastic dominance of empirical mixed strategy measures is used to test the theory with data on 968 books from 10 online retailers

Choosing an organisational form: the case of collaborative procurement initiatives

This paper deals with different organisational forms of collaborative procurement and provides insight into when to use which form. Different forms from the literature are compared with empirical examples to give an overview of forms, which are then described in terms of strategy, skills and organisation. Whilst acknowledging variations, the paper distinguishes between two main forms: virtual networks and third-party organisations. Using empirical data and four theoretical perspectives (transaction cost economics, resource-based view, contingency theory, agency theory), the paper reflects on when which form can be used and presents an overall framework to help choose an organisational for

Toward a process theory of entrepreneurship: revisiting opportunity identification and entrepreneurial actions

This dissertation studies the early development of new ventures and small business and the entrepreneurship process from initial ideas to viable ventures. I unpack the micro-foundations of entrepreneurial actions and new ventures’ investor communications through quality signals to finance their growth path. This dissertation includes two qualitative papers and one quantitative study. The qualitative papers employ an inductive multiple-case approach and include seven medical equipment manufacturers (new ventures) in a nascent market context (the mobile health industry) across six U.S. states and a secondary data analysis to understand the emergence of opportunities and the early development of new ventures. The quantitative research chapter includes 770 IPOs in the manufacturing industries in the U.S. and investigates the legitimation strategies of young ventures to gain resources from targeted resource-holders.Open Acces

Regional Business Networks and the Multinational Retail Sector

In this paper we examine the network relationships of a set of large retail multinational enterprises (MNEs). We analyze under what conditions a flagship-network strategy (characterized by a network of five partners – the MNE; key suppliers; key partners; selected competitors; and key organisations in the non-business infrastructure) explains the internationalisation of three retailers whose geographic scope, sectoral conditions and competitive strategies differ substantially. We explore why and when retailers will adopt a flagship strategy. The three firms are Tesco and The Body Shop, two U.K.-based multinational retailers, and Moet Hennessy Louis Vuitton (LVMH), a French-based global retailer. We find evidence of strong network relationships for all three retailers, yet they embrace network strategies for different reasons. Their flagship relationships depend on each retailer’s strategic use of firm-specific-advantages (FSAs) and country-specific advantages (CSAs). We find that a flagship strategy succeeds in overcoming internal and/or environmental constraints to cross-border resource transfers, which are barriers to foreign direct investment (FDI). We provide recommendations on why and when to use a flagship-based strategy and which type of network partners to prioritize in order to succeed internationally.international retailing, flagship strategy, networks, LVMH, Tesco, The Body Shop, multinational, firm-specific advantages, regional strategy

Confronting corruption in the health sector in Vietnam: patterns and prospects

This repository item contains a single issue of the Health and Development Discussion Papers, an informal working paper series that began publishing in 2002 by the Boston University Center for Global Health and Development. It is intended to help the Center and individual authors to disseminate work that is being prepared for journal publication or that is not appropriate for journal publication but might still have value to readers.Corruption in Vietnam is a national concern which could derail health sector goals for equity, access, and quality. Yet, there is little research on vulnerabilities to corruption or associated factors at the sectoral level. This article examines current patterns of corruption in Vietnam’s health sector, identifies key corruption vulnerabilities, and reviews strategies for addressing corruption in the future. The article builds on the findings and discussion at the sixth Anti-Corruption Dialogue between the Vietnamese Government and the international donor community. Development partners, government agencies, Vietnamese and international non-governmental organizations, media representatives and other stakeholders explored what is known about important problems such as informal payments, procurement corruption, and health insurance fraud. The participants proposed corruption-reduction interventions in the areas of administrative oversight, transparency initiatives and civil society participation, and health reforms to change incentives. The analysis assesses the prospects for success of these interventions given the Vietnamese institutional context, and draws conclusions relevant to addressing health sector corruption in other countries

Trust and Experience in Online Auctions

This paper aims to shed light on the complexities and difficulties in predicting the effects of trust and the experience of online auction participants on bid levels in online auctions. To provide some insights into learning by bidders, a field study was conducted first to examine auction and bidder characteristics from eBay auctions of rare coins. We proposed that such learning is partly because of institutional-based trust. Data were then gathered from 453 participants in an online experiment and survey, and a structural equation model was used to analyze the results. This paper reveals that experience has a nonmonotonic effect on the levels of online auction bids. Contrary to previous research on traditional auctions, as online auction bidders gain more experience, their level of institutional-based trust increases and leads to higher bid levels. Data also show that both a bidder’s selling and bidding experiences increase bid levels, with the selling experience having a somewhat stronger effect. This paper offers an in-depth study that examines the effects of experience and learning and bid levels in online auctions. We postulate this learning is because of institutional-based trust. Although personal trust in sellers has received a significant amount of research attention, this paper addresses an important gap in the literature by focusing on institutional-based trust

An integrative model of the management of hospital physician relationships

Hospital Physician Relationships (HPRs) are of major importance to the health care sector. Drawing on agency theory and social exchange theory, we argue that both economic and noneconomic integration strategies are important to effective management of HPRs. We developed a model of related antecedents and outcomes and conducted a systematic review to assess the evidence base of both integration strategies and their interplay. We found that more emphasis should be placed on financial risk sharing, trust and physician organizational commitment

Congestion, Private Peering and Capacity Investment on the Internet.

This paper presents a model of private bilateral and multilateral peering arrangements between Internet backbone providers when the network is congested. We study how different forms of interconnection and the competitive conditions of the market affect backbones' investments in network and peering point capacities. We show that network and peering point capacities are equilibrium complements; increasing competition reduces capacity investments (under-investment), thus worsening the quality of service both with multilateral and bilateral peering; under bilateral peering the inefficiency is less severe. Because of under-investment, welfare may be lower when the market is more competitive. We also show that asymmetries between backbones, which can take the form of uneven content distribution or product differentiation, may reduce under-investment and improve the quality of service. The introduction of an "inverse capacity interconnection fee" where providers pay each other a fee which is negatively correlated with their installed capacity may play the role of a coordinating mechanism towards a Pareto superior outcome.Internet, peering, congestion, QoS, capacity investment, interconnection
