Access Charges

SummaryCompanies active in electricity generation or supply that also own transmission or distribution network assets are generally presumed to have an economic interest in using its monopoly position as network owner to prevent or hinder competition in other areas of the value chain. This can happen in many ways such as raising rivals’ costs, price squeezes or by providing essential information only to affiliated companies. All of these practices distort a level playing field. In order to limit the risk of such behavior from occurring Member States of the European Union introduced a “regulated third party access” regime under which third parties have a right to access the network in a non-discriminatory manner. It is the purpose of the paper to derive the welfare implications of a regulation of access charges for electricity grids taking the costs of transmission as a benchmark. It shows that a cost-based regulation is second-best optimal only if the gap between the incumbent’s and the downstream entrant’s efficiency is sufficiently large. In all other cases an access charge deviating from the transmission costs is second-best optimal. There is no simple and generally applicable rule for the determination of second-best optimal access charges.

AbstractThe introduction of the Clean energy for all Europeans package by the European Union (EU) led to a significant boost of public and research interest in energy communities. However, since neither their definition nor their goals are clearly defined, there is a very broad field of research on this topic. This paper aims to classify existing research on energy communities and to analyze what this umbrella term looks like in the literature. First, a literature review is conducted with regard to energy communities that have a local scope and are community-owned. The analysis of the results leads to the determination of the following categories for the existing literature on energy communities: the terminology used to refer to energy communities, components of energy communities, and their characteristics and structure. The review affirms that space-saving and easily constructible components are used the most, with photovoltaics (PV) and storage at the forefront. Our results also show that a third-party aggregator can be a vital part of an energy community with various functions, from managing the community’s energy flow and local market to trading energy with the grid. Taking this into consideration, we conclude that the use of aggregators is a good way to make the formation of energy communities easier, especially for people without an engineering background.

Access Charges

The regulation of track access charges within the European Union is based on the economic principles of first and second best pricing. In order to obtain an allocative efficiency it is crucial to determine the marginal costs of operating the train services – the so-called direct costs. Even though the Implementing Regulation (EU) 2015/909 specifies the modalities for the calculation of direct costs, a broad range of different values for direct costs can be observed across Member States. However, the discussion of the level of direct costs is driven in particular by econometric, engineering and cost accounting aspects – an economic analysis is missing despite the welfare-economic concept of track access charges. For that reason, this paper discusses the welfare economic effects of different suitable values for direct costs.It will be shown that both a welfare maximising first best track access charging and, in most cases, also a second best charging will result in boundary solutions for direct costs. However, it also becomes obvious that from a welfare-economic perspective there is no general recommendation for adopting the lowest suitable direct costs. Any allocatively efficientregulation of track access charges must consequently consider the specific situation of each market segment separately.

AbstractBased on the theory of trade added value, this paper discusses the potential actual trade scale and benefit damage degree of the two countries under the background of big country game by measuring the real trade scale of China and the USA, simulating the economic impact of tariffs imposed by China and the USA and utilizing Wang–Wei–Zhu (WWZ) method to decompose the potential changes in Sino-US trade. The results show that: firstly, the size of China-US trade in terms of total value is significantly overestimated and China's overall trade with the USA in 2001–2014 was overestimated by an average of 3.06 percent, of which goods trade was overestimated by 8.06 percent. Secondly, although tariff increases can reduce the degree of trade imbalance between China and the USA to some extent, the adverse effects are mutual and global, and the European Union, the Association of Southeast Asian Nations (ASEAN), Japan and Canada become the main transfer countries of Sino-US trade. Thirdly, the pattern of China's final exports and the US' intermediate exports determines that China's trade interests are more damaged than those of the USA. It is proved that there is a big gap between China and the USA in the depth and breadth of China's participation in the value chain division of labor and the trade scale measured by Gross Domestic Product is more instructive than the total value.

This study was conducted to develop a selective and sensitive method for the determination of bisphenol A (BPA) levels in milk and dairy products. A method based on solvent extraction with acetonitrile and solid-phase extraction (SPE) was developed for the analysis of BPA in milk, yogurt, cream, butter, pudding, condensed milk, and flavored milk, and a method using two SPE cartridges (OASIS HLB and Florisil cartridge) for skim milk was also developed. The developed methods showed good recovery levels (77 to 102%) together with low detection limits (1 μg/liter for milk, yogurt, pudding, condensed milk, flavored milk, and skim milk and 3 μg/liter for cream and butter). These methods are simple, sensitive, and suitable for the analysis of BPA in milk and dairy products. When 40 milk and dairy products were analyzed by the proposed methods, BPA was not identified in noncanned products, but its levels ranged from 21 to 43 μg/kg in canned products, levels that were 60- to 140-fold lower than the migration limits in the European Union and Japan.

Food is essential to our survival, yet the Food and Agriculture Organization of the United Nations (FAO) estimates that about 820 million people were undernourished in 2018. In this context, food waste generation is a particularly salient issue. Wasting food means missing opportunities to feed the growing world population and consuming scarce resources, such as land, water and energy used in the production, processing, distribution and consumption of food. Firms in HORECA (hospitality, restaurant and catering) represent a considerable share of total food waste and, more importantly, are characterized by an overall low sense of awareness about the sustainability-oriented innovation opportunities and challenges of minimizing food waste. This article draws on an in-depth case study to explore the use of technological advancements in downstream value chain. This case study draws on a tech startup providing services for HORECA companies to address a new way for companies to solve the food waste challenge. Adopting technological innovations to quantify and minimize wastage via collaborations with third-party companies can be a strategic and cost-effective way to supplement a company’s open innovation activities.

The European Union (EU)–Turkey deal consolidated a shift in the EU’s migration policy. The deal is the culmination of the dominance of the security frame and depicts the continuous externalization of the EU’s responsibility of asylum protection and burden sharing. The strengthening of the security frame has weakened the humanitarian norms that previously dictated EU’s behaviour. This has led to the EU losing some of its comparative advantages in negotiations. Simultaneously, the instrumentalization of the value of asylum, paired with an increased number of asylum seekers, has given negotiation leverage to the neighbouring countries turned service providers. These changes in perception and norms have created a power shift, at the disadvantage of the EU, creating a more leveled playing field for negotiations between the parties. This article tracks the historical shifts in the global refugee regime to explain how today’s situation was created. Hereby, the existence of two competing cognitive frames—humanitarian and security—is assumed, tracked and analysed. While looking at the EU–Turkey deal, the article shows that the EU has started treating refugees as a security problem rather than a humanitarian issue, breaking the normative fabric of the refugee regime in the process. The article also displays how Turkey was able to capitalise on this new reality and engage with negotiations of other neighbouring countries of EU that point towards a change of dynamics in the global refugee regime.

In this second part of a two-part article we continue our consideration of how global energy value chains could be managed more sustainably through blockchain by greatly increasing transparency. The aim is to use this transparency to incentivise more sustainable behaviour on the part both of energy producers and suppliers and of consumers. Incentives of this kind are market based, and so we have concentrated on market-based instruments in the energy sector, emphasising those that decrease the CO2 footprint of energy consumption, such as emissions trading schemes and renewable energy certificates. Blockchain can enhance transparency by improving the quality of, and access to, sustainability-related information. However, existing laws and regulatory frameworks that govern market-based instruments may prevent these benefits from becoming fully realised. We review the governance frameworks of market-based instruments in several international jurisdictions (Brazil, India, Kazakhstan, Mexico, South Africa and Ukraine, as well as the European Union with particular reference to the Netherlands and United Kingdom (which was a member of the EU at the time of this writing), to ascertain how laws, rules and regulations may limit transparency of sustainability information. We also consider jurisdictional differences to identify difficulties in the creation of a global framework for managing sustainability information from market-based instruments. Jurisdictional differences mean that a one-size fits all solution may not be possible. To overcome this, we propose a blockchain governance model, using aggregated blockchains and peering agreements. It allows flexibility when disclosing information, through layering of permissions, and this means that it should be possible to construct a transparency system which complies with existing domestic legal and regulatory requirements, rather than requiring major legal and regulatory change.

Abstract A collaborative study IMEP-115 was organized by the European Union Reference Laboratory for Heavy Metals in Feed and Food (EURL-HM) to validate a method for the determination of methylmercury in seafood. The method was based on a liquid–liquid extraction with an organic solvent and with an aqueous cysteine solution. The final quantitation was done with an elemental mercury analyzer. Fifteen laboratories experienced in elemental mercury analyses, from 10 European countries, took part in the exercise. Five test items were selected to cover the concentration range from 0.013 to 5.12 mg/kg. All test items were reference materials certified for the methylmercury mass fraction: DOLT-4 (dogfish liver), TORT-2 (lobster hepatopancreas), SRM 2974a (mussel), SRM 1566b (oyster), and ERM CE-464 (tuna). Participants also received a bottle of ERM CE-463 (tuna) to test their analytical method before starting the collaborative study. Method validation showed adequate accuracy and acceptable precision for all test items, thus fitting its intended analytical purpose. The repeatability RSD ranged from 3.9 to 12.3%, while the reproducibility RSD ranged from 8.4 to 24.8%.

In recent decades, more and more consumers—referred to as “green consumers”—are willing to incorporate environmentally responsible decisions into their purchasing behaviors. This tendency is particularly notable in the European Union, the USA, and China. From a research perspective, while recent studies on remanufacturing have investigated optimal practices in regard to green consumerism, they have failed to address the flexibility manufacturers are afforded to outsource remanufacturing operations to third parties. In practice, some brand-name manufacturers—such as IBM, Land Rover, and Sun—do indeed outsource their remanufacturing operations. To further our understanding of the implications of differentiated structures for remanufacturing operations under green consumerism, we developed two models: one for a manufacturer undertaking remanufacturing themselves (Model M), and one for a manufacturer outsourcing it to a third-party remanufacturer (Model O). Our results indicate that, for markets with significant green consumerism, Model M tends to result in more remanufactured units and creates higher profitability for the manufacturer. However, under certain conditions, this model may also result in greater harm to the environment due to the comparative excess of manufacturers in the remanufacturing process. This implies that environmental groups and agencies should not only aim to encourage green consumerism, but should also focus their attention on the channel structures for remanufacturing.
