    Myriad policy measures aim to reduce greenhouse gas emissions from the electricity sector, promote generation from renewable sources, and encourage energy conservation. To what extent do innovation and energy efficiency (EE) market failures justify additional interventions when a carbon price is in place? We extend the model of Fischer and Newell (2008) with advanced and conventional renewable energy technologies and short and long-run EE investments. We incorporate both knowledge spillovers and imperfections in the demand for energy efficiency. We conclude that some technology policies, particularly correcting R&D market failures, can be useful complements to emissions pricing, but ambitious renewable targets or subsidies seem unlikely to enhance welfare when placed alongside sufficient emissions pricing. The desirability of stringent EE policies is highly sensitive to the degree of undervaluation of EE by consumers, which also has implications for policies that tend to lower electricity prices. Even with multiple market failures, emissions pricing remains the single most cost-effective option for reducing emissions.

    Die Wirkungen von Stoffströmen sind abhängig von der umgesetzten Menge und den spezifischen Auswirkungen pro Mengeneinheit. Die Menge der Extraktion an Primärmaterial aus der Umwelt kann als vorsorgeorientierter Indikator für ein unspezifisches Umweltbelastungspotential herangezogen werden. Die Materialintensitäts-Analyse ermittelt den kumulierten Materialaufwand (= Material Input) nach fünf Hauptkategorien und setzt diesen in Beziehung zum gewünschten Nutzen (= pro Service-Einheit). Beispielhaft wird die Materialintensität verschiedener Systeme der Energieversorgung und des Wasser- und Abwassermanagements verglichen. Ein integriertes Ressourcenmanagement schließt bei einer umfassenden Systemsicht neben einer Minimierung des Ressourcenaufwandes auch die Verminderung kritischer Emissionen ein. Es erfordert ein sektorübergreifendes Stoffstrommanagement und die Berücksichtigung ökonomischer, technologischer, organisatorischer und sozialer Aspekte sowie der regionalen Besonderheiten. Ansätze hierzu werden vorgestellt. The impacts of material flows depend on the flow volume and the specific impacts per unit of flow. The volume of primary materials extracted from the environment can be used as an indicator of unspecific impact potential. Material intensity analysis determines the cumulative material requirements (= Material Input) according to five main categories. The input is related to the utility and normalized on a per service basis. As examples, the material intensity of different systems for energy supply and for water and waste water management is compared. Based on a comprehensive systems perspective Integrated Resource Management comprises minimization of resource requirements as well as reduction of critical emissions. It demands for a sector encompassing material flow management and also considers economical, technological, organisational and social aspects with regard to regional specificities. Approaches to this end are being described.

    This study analyses the diffusion of renewable energy (RE) technologies. It analyses the transition dynamics as the sector broadens its energy mix and changes its capital stock. This shift is found to be desirable from an environmental, geopolitical and economic perspective. Yet, it greatly increases the technical and industrial complexity, and is not Pareto-efficient. We focus on wind and solar power, and discuss their promoted deployment against the energy policy principles of the EU. Put drastically, the promotion of "sustainability" undermined "competitive" mechanisms. This has potentially adverse effects on the "security of supply" due to the market design that seeks to keep prices low. RE outperforms conventional facilities. Emergency capacities, however, are also exiting, especially in Germany. If markets are seen as one, there seems to be a threshold of wind and solar power that the current back-up system can incorporate without risking the security of supply. The policy relevant crux lies in conflicting mechanisms: the top-down promotion and planning policies undermine the bottom-up market selection. Then again, without interventions the market does not provide the socially desired outcomes. If tensions aggravate further, the implementation of the new technology base is likely to stall. In addition, the generous promotion resulted in the fast deployment of RE, which may have shortened the "formative phase" of the diffusion process. A longer formative phase would have created more learning effects and fostered more incremental innovations. In addition, costs of subsidies are allocated differently across countries. Mechanisms that allocate costs to the public budget have greater acceptance rates than budget neutral ones that assign costs to consumers. The latter affect households asymmetrically across income classes. Also ownership structures changed; a large number of actors now constitute the energy sector. Citizens increasingly appeared as producers and investors, which stimulated the social acceptance of RE, and in some cases unlocked initially unfavourable vested interests.

    This paper presents a theoretical and empirical analysis of liquidity in the German intraday market for electricity. Two models that aim at explaining intraday liquidity are developed. The first model considers the fundamental merit-order and intraday adjustment needs as the drivers of liquidity in a perfectly competitive market. The second model relaxes the assumption of perfect competition in the intraday market and assumes that the trading behavior of profit maximizing market participants influences the liquidity provision. The relevance of commonly used liquidity indicators like the bid ask-spread, resiliency, market depth, price variance, delay and search costs as well as trading volume and the number of trades are analyzed with respect to both models of liquidity. The empirical findings indicate that liquidity in the German intraday market can be explained by the trading model while the purely fundamental model is rejected.

    This paper explores the relation between the regulation of monopolistic upstream prices and the incentives of a vertically integrated input monopolist to discriminate third parties on the downstream market. Currently, this is an issue in network industries like telecommunications, electricity and railways and has sparked off a controversy in the literature. The paper examines how the incentives to discriminate depend on the level of the upstream prices, the potential competitiveness of the downstream market and the efficiency of the competitors as compared to the integrated firm's downstream subsidiary. The insights are applied to the electricity supply industry in Germany.

    Lack of transmission capacity hampers the efficient integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate to what extent the expansion of the transmission grid promotes competition, efficiency, and welfare. This work proposes a three-stage model for grid investment: a benevolent planner decides on network upgrades; she considers the welfare benefits of investment through a reduction of market power exertion by strategic generators. These firms anticipate their impact on the Independent System Operator and are able to exert market power, in particular when lines are congested. We illustrate the model on a simple three-node network. Results indicate that network expansion indeed provides a suitable way of enhancing welfare due to a reduction of market power potential.

    I estimate the level of emissions cost pass-through to hourly wholesale electricity prices in Germany, based on spot market data. I control for contemporaneous shocks to demand and supply by constructing a detailed supply curve for fossil generation, and intersecting it with residual demand for fossil-based electricity for every hour. Determining the marginal generator allows me to use marginal fuel and carbon costs (rather than prices) as explanatory variables in order to identify the level of cost pass-through directly and with a high level of precision. I find that carbon costs are passed through to electricity prices by at least 84 %, with a central range of 98 %-104 % for different load periods. My results suggest that there is no economic reason for free allowance allocation to the electricity sector, and thus validate the updated allocation rules in Phase 3 of the European Union Emissions Trading Scheme.

    Electricity networks currently face massive investment requirements. This paper argues that, given the investment requirements, (international) benchmarking is not an adequate tool for the regulation of transmission system operators (TSO). Errors in the outcomes of benchmarking will likely distort network investment and therefore the costs of doing it wrong are high. The paper discusses options to reduce the weight of benchmarking in TSO regulation and options that do not rely on benchmarking at all. Overall, facing massive investment requirements, it seems desirable to switch to a regulatory system with ex-ante investment approval and away from ex-post benchmarking.

    What is a good balance between competition and coordination in network industries? Network unbundling aims to promote competition, but this has to be balanced against the downside of unbundling: firm-internal coordination falls away and must be replaced by external market mechanisms. This is a non-trivial task. The cost of flawed coordination as a result of fragmentation can be substantial and policy should focus more on the cost of coordination and on governance structures to secure coordination. This paper examines three persistent sources of flawed coordination: 1) a regulation versus unbundling dilemma, 2) difficulties with optimal network charging and 3) strategic behavior resulting in misaligned incentives. Practical relevance is underlined with lessons from (European) electricity and railways.

    The purpose of this research is to evaluate the impact of vertical unbundling on German electric utilities. Our research mainly relies on in-depth interviews with sector-experts from the German utilities. We will discuss both short-term changes and the long-term impact on competition in the electricity market as well as the impact on costs and security of supply. Overall, we have two main conclusions. First, the major step in the unbundling process is from "lean legal unbundling" to "fat legal unbundling"; additional steps beyond that are small, both in benefits and in costs. Second, the benefits of unbundling in terms of increased competition do not come for free: unbundling is costly and it is important to balance cost and benefits in the reform process.

    In principle, portfolio optimization in electricity markets can make use of the standard mean-variance model going back to Markowitz. Yet a key restriction in most electricity markets is the limited liquidity. Therefore the standard model has to be adapted to cope with limited liquidity. An application of this model shows that the optimal hedging strategy for generation portfolios is strongly dependent on the size of the portfolio considered as well as on the variance-covariancematrix used and the liquidity function assumed.

    The instability and informality that characterize hybrid political orders and its effects on entrepreneurs remains largely unexplored in the scholarly literatures. In this paper we provide initial findings from the case of entrepreneurs' access to electricity in Lebanon. Using quantitative and qualitative methods we find that political connections significantly influence the investment decisions of entrepreneurs and the performance of their firms. In general, a hybrid political order imposes a 'tax' on entrepreneurship by channelling entrepreneurial talent into lobbying and bribery; by reinforcing male and family-owned dominance in business; and by skewing investment decisions. Specifically, we find that family firms whose entrepreneurs engage in bribery, and who obtain government contracts alleviate electricity problems and perform better.
