    Abstract: We investigate the effectiveness of policies in favor of innovation in renewable energy under different levels of competition. Using information regarding renewable energy policies, product market regulation and high-quality green patents for OECD countries since the late 1970s, we develop a pre-sample mean count-data econometric specification that also accounts for the endogeneity of policies. We find that renewable energy policies are significantly more effective in fostering green innovation in countries with deregulated energy markets. We also find that public support for renewable energy is crucial only in the generation of high-quality green patents, whereas competition enhances the generation of green patents irrespective of their quality.

    Abstract: Accident externalities are among the most important external costs of road transport. We study the regulation of these when insurance companies have market power. Using analytical models, we compare a public-welfare maximizing monopoly with a private profit-maximizing monopoly, and markets where two or more firms compete. A central mechanism in the analysis is the accident externality that individual drivers impose on one another via their presence on the road. Insurance companies will internalize some of these externalities, depending on their degree of market power. We derive optimal insurance premiums, and "manipulable" taxes that take into account the response of the firm to the tax rule applied by the government. Furthermore, we study the taxation of road users under different assumptions on the market structure. We illustrate our analytical results with numerical examples, in order to better understand the determinants of the relative performance of different market structures.

    Abstract: The purpose of this study is to analyze the cost efficiency of electricity distribution systems in order to enable regulatory authorities to establish price- or revenue cap regulation regimes. The increasing use of efficiency analysis in the last decades has raised serious concerns among regulators and companies regarding the reliability of efficiency estimates. One important dimension affecting the reliability is the presence of unobserved factors. Since these factors are treated differently in various models, the resulting estimates can vary across methods. Therefore, we decompose the benchmarking process into two steps. In the first step, we identify classes of similar companies with comparable network and structural characteristics using a latent class cost model. We obtain cost best practice within each class in the second step, based on deterministic and stochastic cost frontier models. The results of this analysis show that the decomposition of the benchmarking process into two steps has reduced unobserved heterogeneity within classes and, hence, reduced the unexplained variance previously claimed as inefficiency.

    Abstract: Energy and climate policies are usually seen as measures to internalize externalities. However, as a side effect, these policies redistribute wealth between consumers and producers, and within these groups. While redistribution is seldom the focus of the academic literature in energy economics, it plays a central role in real world policy debates. This paper compares the redistribution effects of two major electricity policies: support schemes for renewable energy sources, and CO2 pricing. We find that the redistribution effects of both policies are large, and they work in opposed directions: while renewables support transfers wealth from producers to consumers, carbon pricing does the opposite. More specifically, we show that moderate amounts of wind subsidies leave consumers better off even if they bear the costs of subsidies. In the case of CO2 pricing, we find that while suppliers as a whole benefit even without free allocation of emission certificates, large amounts of producer surplus are redistributed between different types of producers. These findings are derived from an analytical model of electricity markets, and a calibrated numerical model of the Northwestern European integrated power system. Our findings imply that a society with a preference for avoiding large redistribution might prefer a mix of policies, even if CO2 pricing alone is the first best climate policy in terms of allocative efficiency.

  5. By: Oskar Lecuyer (CNRS, UMR 8568 CIRED, Nogent-sur-Marne and EDF R&D, Clamart); Philippe Quirion (CNRS, UMR 8568 CIRED, Nogent-sur-Marne, France)
    Abstract: This article constitutes a new contribution to the analysis of overlapping instruments to cover the same emission sources. Using both an analytical and a numerical model, we show that when the risk that the CO2 price drops to zero and the political unavailability of a CO2 tax (at least in the European Union) are taken into account, it can be socially optimal to implement an additional instrument encouraging the reduction of emissions, for instance a renewable energy subsidy. Our analysis has both a practical and a theoretical purpose. It aims at giving economic insight to policymakers in a context of increased uncertainty concerning the future stringency of the European Emission Trading Scheme. It also gives another rationale for the use of several instruments to cover the same emission sources, and shows the importance of accounting for corner solutions in the definition of the optimal policy mix.

  6. By: Gaudiny, Germain; Saavedra Valenzuela, Claudia
    Abstract: We study the implementation of reasonably efficient operator margin squeeze tests by National Regulatory Authorities in European telecommunications markets. We provide a theoretical framework in which we show how regulatory authorities deal with the asymmetries between the entrants and the incumbent by adjusting the equally efficient operator margin squeeze test used in competition policy. Using this framework, we build a benchmark of implementation choices by inspecting authorities' guidelines, market analyses and decisions. We find that some implementation choices are very similar across the authorities' decisions, whereas some others are dealt with quite heterogeneously. --

  7. By: Jeffrey V. Butler; Enrica Carbone; Pierluigi Conzo; Giancarlo Spagnolo
    Abstract: This paper reports results from a laboratory experiment exploring the relationship between reputation and entry in procurement. We propose a procurement model with reputation and entry assigning to the entrant a reputational advantage of varying size across treatments. There is widespread concern among regulators that favoring suppliers with good past performance, a standard practice in private procurement, may hinder entry by new (smaller or foreign) firms in public procurement markets. Our results suggest that while some reputational mechanisms indeed reduce the frequency of entry, appropriately designed reputation mechanisms actually stimulate it. Since quality increases but not prices, our data also suggest that the introduction of reputation may generate large welfare gains for the buyer.

    Abstract: The paper examines the financial costs of energy-efficiency and environmental policies that directly affect domestic electricity and gas bills in the UK over time. It also attempts for the first time to work out the current distributional impacts of these policies and others that act as income supplements thereby presenting a consistent picture across time and income deciles. Figures suggest that during 2000-11, the percentage share of policy costs in typical domestic electricity and gas bills rose by 14% and 4%, respectively. This reflects a growing share of policy costs in bills which is relatively small for gas customers but significant for electricity customers. Moreover, distributional impacts of the energy-policy mix highlight the issue of imperfect targeting of low-income households during 2009-10. The study also indicates that during 2010-11, 76% of the funds for energy-efficiency schemes were handled by the private sector. Given that a long-term solution to fuel poverty lies in improving thermal efficiency of houses; this research draws attention towards the need for definitive evidence on the ways in which energy suppliers charge policy costs from their domestic customers. This would facilitate in making the future policies more empirically grounded. In time, a clearer understanding of official statistics on energy bills will go a long way in restoring consumers’ trust in the pricing mechanism of the energy market.

  9. By: Borraz, Fernando; Pampillon, Nicolas Gonzalez; Olarreaga, Marcelo
    Abstract: The objective of this paper is to explore the impact of Uruguay's privatization and subsequent nationalization of water services on network access and water quality. The results suggest that although the early privatization of water services had little impact on access to the sanitation network, the subsequent nationalization led to an increase in network access at the bottom of the income distribution as well as an improvement in water quality.

    Abstract: The present paper investigates the functioning of an Emission Trading System (ETS) and its impact on the diffusion of environmental-friendly technological innovation in the presence of firms’ strategic behaviours and sanctions to non-compliant firms. For this purpose, we study an evolutionary game model with random matching, namely, a context in which a population of firms interact through pairwise random matchings. We assume that each firm has to decide whether to adopt a new clean technology or keep on using the old technology that requires pollution permits to operate and that the strategy whose expected payoff is greater than the average payoff spreads within the population at the expense of the alternative strategy (the so-called replicator dynamics). We investigate the technological dynamics and the stationary states that emerge from the model. From the analysis of the model, we show that by properly modifying the penalty on non-compliant firms, it is possible to shift from one dynamic regime to another and that an increase in permits trade can promote the diffusion of innovative pollution-free technologies.

  11. By: Roger Fouquet
    Abstract: This paper investigates how the demand for energy services has changed since the Industrial Revolution. It presents evidence on the income and price elasticities of demand for domestic heating, passenger transport and lighting in the United Kingdom over the last two hundred years. It finds that the general trend in income elasticity followed an inverse U-shape curve and in price elasticity was a U-shape curve, as the economy developed and energy service prices fell. However, these general trends were disrupted by energy and technological transitions, which boosted demand (either by encouraging poorer consumers to fully enter the market or by offering new attributes of value to wealthier consumers). This evidence suggests that energy service consumption in developing economies is likely to continue rising rapidly and in industrialised countries is not likely to decline. Thus, in the absence of a full transition to low carbon energy sources and technologies, this implies long run increases in global carbon dioxide emissions.

    Abstract: This paper provides new empirical evidence on the efficiency of Italian airports. Analysing data on 2010 trough conditional e?ciency measures, we find that competition affects mostly the frontier of best performers, whilst airports that are lagging behind are less influenced by it. By applying a novel two stage approach, we show that competition has an inverse U-shape impact. Finally, the bi-modal shape of the distribution of pure efficiency indicates the existence of two differently managed groups of airports.
