Demand for storage of natural gas in northwestern Europe. Trends 2005-2030

The seasonal demand for natural gas requires supply flexibility. This “swing” is now largely provided in northwestern Europe by indigenous production. Declining reserves will increase the dependency on imports from far-off sources, which are less flexible. Hence, flexibility must be provided by additional storage. We estimate that in 2030 between 10 (with no strategic storage) and 29 (with 10 per cent strategic storage for imports from non-EU countries) billion cubic meter of working gas volume will be required, in addition to the existing 40 billion cubic meters. This estimation is based on production and consumption forecasts for natural gas and observations of the relationship between the supply and demand of gas and the supply and demand of flexibility in the period 1995-2005. We provide different scenarios to check for the robustness of our results. We discuss the impact of third-party access to storage facilities on incentives to close the storage gap, as well as policy implications of strategic storage obligations.Seasonal swing, strategic storage obligations, thirdparty access

An economic analysis of trade-secret protection in buyer-seller relationships

The economic analysis of trade-secret protection has traditionally focused on the interests of companies to conceal information from competitors in order to gain a competitive advantage through trade-secret law. This has neglected cases in which the interest is not in concealing information from competitors, but from trading partners. We investigate the social efficiency effects of trade-secret protection in such cases. Many results from economic theory state that asymmetric information (and therefore also its legal protection) is socially undesirable since it leads to inefficient trade. At the same time, protecting private information might create incentives for socially desirable investments. We model this trade-off in a simple buyer-seller model and find that, indeed, trade-secret protection has ambiguous welfare effects. However, a simple, informationally undemanding rule, conditioning the applicability of legal protection on a minimum investment by the informed party to conceal the information, helps to apply trade-secret protection only when it increases welfare. This rationalizes important features of current legal practice.disclosure of information, hold-up problems, trade secrets

Mobile termination and collusion, revisited

The standard model by Laffont, Rey and Tirole (1998) treats termination fees as an instrument to increase market power in a one-shot game of horizontal product differentiation. We offer an alternative view in an infinitely repeated Bertrand competition. We focus on symmetrical call-ing patterns and investigate simple two-part tariffs for two types, as well as general non-linear tariffs for two types and for a continuum of types. In this framework, termination fees make deviations from the collusive outcome less attractive. The optimum deviation strategy is usually to try to attract the high valuation customers since they exhibit the highest profits. Thus, a deviator will have a pool of high users which will have more outgoing than incoming calls, implying net termination payments. A cooperatively chosen termination rate can increase the deviator’s cost and thereby always stabilizes collusion.Two way access, mobile telecommunications, non-linear tariffs

Legal unbundling can be a golden mean between vertical integration and ownership separation

We study an industry in which an upstream monopolist supplies an essential input at a regulated price to several downstream firms. Legal unbundling means in our model that a downstream firm owns the upstream firm, but this upstream firm is legally independent and maximizes its own upstream profits. We allow for non-tariff discrimination by the upstream firm and show that under quite general conditions legal unbundling never yields lower quantities in the downstream market than ownership separation and integration. Therefore, typically, consumer surplus will be largest under legal unbundling. Outcomes under legal unbundling are still advantageous when we allow for discriminatory capacity investments, investments into marginal cost reduction and investments into network reliability. If access prices are unregulated, however, legal unbundling may be quite undesirable. (C) 2011 Elsevier B.V. All rights reserved

Using Forward Contracts to Reduce Regulatory Capture

Optimal incentive regulation uses transfers. If the regulator is corruptible, the regulated firm can benefit by manipulating the regulator's assessment regarding the distribution of payoff relevant variables, which determine the structure and size of optimal transfers. We show how substituting outcome-contingent transfers by an obligation to sell simple financial contracts to well informed financial investors can reduce the scope for manipulation. A possible application would be an electricity transmission network operator whose actions can affect electricity prices. In a simple moral hazard model, first-best outcomes can be implemented by forcing the network operator to auction off forward contracts on the electricity price. We study the optimal mixture of financial instruments and regulatory transfers given different informational assumptions and imperfections of financial markets

Investment coordination in network industries: the case of electricity grid and electricity generation

Liberalization of network industries frequently separates the network from the other parts of the industry. This is important in particular for the electricity industry where private firms invest into generation facilities, while network investments usually are controlled by regulators. We discuss two regulatory regimes. First, the regulator can only decide on the network extension. Second, she can additionally use a capacity market with payments contingent on private generation investment. For the first case, we find that even absent asymmetric information, a lack of regulatory commitment can cause inefficiently high or inefficiently low investments. For the second case, we develop a standard handicap auction which implements the first best under asymmetric information if there are no shadow costs of public funds. With shadow costs, no simple mechanism can implement the second best outcome

Netting of capacity in interconnector auctions

Scarce interconnector capacities are a severe obstacle to transregional competition and a unified market for electricity in the European Union. However, physically the interconnectors are rarely used up to capacity. This is due to the fact that the current allocation schemes make only limited use of the fact that currents in opposing directions cancel out. We propose a "netting" auction mechanism which makes use of this and in which even small transmission capacities can generate large competitive pressure in adjacent markets. Netting increases the usage of capacity and reduces the auctioneer's incentive to withhold capacity from the auction.Divisible good auctions, interconnector, electricity marktes, competition policy
