According to the European Commission Recommendation for setting copper and fiber wholesale prices where cost orientation is imposed as a remedy, National Regulatory Authorities (NRAs) should adopt a Bottom-UP Long-Run Incremental Cost Plus (BU LRIC+) costing methodology that estimates the current cost that a hypothetical efficient operator would incur to build a modern efficient Next Generation Access (NGA) network. The starting point of modeling an efficient operator investing in NGA networks is the network modeling approach. In this paper, we compare the most widely adopted network modeling approaches in terms of wholesale fiber-to-the-home (FTTH) prices. In particular, the modified scorched node approach is compared to the extreme cases of the scorched node and the scorched earth approaches. The comparison between the aforementioned scenarios sheds light on the impact of each approach on the wholesale FTTH prices. The main finding of this paper is that the scorched earth approach leads to a maximum of 10% reduction in the short-term access prices compared to the most inefficient scorched node approach, whereas further extending its optimizations by optimizing the number of central offices, both the short-term and long-term wholesale price reductions are quite significant (more than 20%) regardless of service speeds. Consequently, NRAs should consider a geographically differentiated modeling approach when regulating the wholesale market by adjusting the level of scorching in each area and network segment according to the investment plans of telecom operators. An appropriate variation of the modeled network operator's efficiency is expected to more accurately represent the costs of a reasonably efficient operator based on the real market conditions and a forward-looking perspective. These findings provide valuable information to both network operators and telecom regulators.  相似文献

This paper extends previous research examining wholesale market shares of mobile network operators (MNOs). This study demonstrates that wholesale market concentration has decreased over time because of the increase of competition of MNOs for hosting mobile virtual network operators (MVNOs). However, differences in wholesale market shares between MNOs have not disappeared. We propose that those operators that are late entrants in a market and belong to an international group with a proactive attitude towards hosting virtual operators positively influences wholesale market shares of MNOs. The empirical analysis is based on a panel data from 2000 to 2010 corresponding to MNOs and virtual operators in five European countries with high development of the virtual mobile industry. By closely examining KPN we show how being an international mobile group specialising in the wholesale market across Europe has enabled it to exploit complementarities that exist between traditional and virtual businesses.  相似文献

This paper considers two competing supply chains, each with multiple upstream suppliers producing complementary products and selling to a single buyer (e.g., assembler or retailer), who then sells the finished assembled product to a market that involves both demand uncertainty and competition. Our main research questions focus on what supply chain structure (integration vs. decentralization) and which contracting strategy a business should choose. We find that supply chains that decentralize perform better under strong market competition (i.e., high degree of product substitution between supply chains). However, when a large number of suppliers exist, supply chains that integrate perform better. When decentralized structures are used for both supply chains, a consignment with revenue sharing contract generally outperforms a wholesale price contract from the downstream retailer's point of view. Interestingly, for a supplier, a wholesale price contract, which pushes all demand risks to the downstream retailer, might not be preferred. For the entire supply chain, one contract strategy can outperform another depending on the degree of competition, the cost share of the buyer, and the number of suppliers.  相似文献

Network operators are increasingly competing with triple play offers from cable providers for both broadcast customers and telecommunications customers. In recent years they have invested in IPTV platforms and launched their own IPTV services. This has brought a new question on the regulatory agenda: shall network operators be obliged to offer wholesale access to their IPTV platform? And if yes, should the new wholesale IPTV product be regulated in the same way as traditional wholesale access? Or should traditional regulation be modified? While the majority of countries have so far no regulatory rules in place, some national regulators have started to become active in this market segment.  相似文献

In this paper, various equilibria are analyzed according to the leader–follower relationship between vertically integrated incumbents when downstream entries are present. This analysis broadens our understanding of the incentives involved in deciding the wholesale price, which can be applied to explain the different situations of diffusion of mobile virtual network operators in the telecommunications market. Several implications are derived to facilitate effective policy formulation and management.  相似文献

This paper analyzes the evolution of prices and competition in intra-EU international roaming markets. It addresses three main research questions: (i) to what extent have market forces by themselves brought competition to retail roaming markets? (ii) Has the evolution of market dynamics in wholesale roaming improved competition? (iii) Is wholesale regulation sufficient to lead to a reduction in retail roaming prices? Data show that there has been little price-based competition both at wholesale and retail levels, despite prices being well above costs and the significant margins allowed by regulation. Available data from the period preceding the entry into force of the first EU roaming regulation also point to the same conclusion. Lack of competitive pressure in retail roaming markets and inelastic demand give little incentives for retail roaming service providers to lower prices. Wholesale international roaming markets have complex competition dynamics. They are characterized by the reciprocity of wholesale roaming agreements and traffic internalization inside transnational groups. These circumstances limit price competition at the wholesale level. The traditional regulatory approach applied to electronic communication markets has been primarily focused on wholesale regulation. However, empirical evidence shows that even if wholesale charges are reduced, retail roaming markets continue to operate at very high retail margins (for example, more than 200% retail mark-up over wholesale charges for data roaming services and incoming calls). This proves that in international roaming markets wholesale charge reductions are not necessarily passed on to retail prices. It can thus be inferred that wholesale price regulation alone is in most cases not sufficient to ensure that benefits are passed through to end users.  相似文献

Supply function equilibria with capacity constraints and pivotal suppliers   总被引:1,自引:0,他引:1  
The concept of a supply function equilibrium (SFE) has been widely used to model generators' bidding behavior and market power issues in wholesale electricity markets. Observers of electricity markets have noted how generation capacity constraints may contribute to market power of generation firms. If a generation firm's rivals are capacity constrained then the firm may be pivotal; that is, the firm could substantially raise the market price by unilaterally withholding output. However the SFE literature has not fully considered the impact of capacity constraints and pivotal firms on equilibrium predictions. We characterize the set of symmetric supply function equilibria for uniform-price auctions when firms are capacity constrained and show that this set is increasing as capacity per firm rises. We provide conditions under which asymmetric equilibria exist and characterize these equilibria. In addition, we compare results for uniform-price auctions to those for discriminatory auctions, and we compare our SFE predictions to equilibrium predictions of models in which bidders are constrained to bid on discrete units of output.  相似文献

Entry into Swedish Retail and Wholesale Trade Markets   总被引:1,自引:0,他引:1  
This paper examines, using a zero-inflated negative binomial regression model, what determined entry into the Swedish retail and wholesale trade markets between 1990 and 1996. According to the results, high returns on equity and low sunk costs seemed to attract more entry into retail trade industries, while recent entry and higher total industry sales were associated with more entry into both retail and wholesale trade local markets.  相似文献

The paper analyzes the functional relationship between profitability and market share for type of businesses in the PIMS data base. Although a linear relationship has been imposed in other studies, our result shows that empirically it seems a poor representation of the data. In addition, three observations seem to be most evident. First, small-share businesses were not per se less successful than larger business units. In the service market and the market for raw or semi-finished materials small-share businesses were just as profitable or even more profitable than larger business units. Second, some businesses were ‘stuck in the middle’, which was most evident in the service market but also in the retail and wholesale markets. Third, very large-share businesses were often less profitable. A critical market share was identified as between 65 and 70 percent. Beyond that level the ROI decreased.  相似文献
