Poland has great potential for the development of renewable energy sources. The implementation of support systems dedicated to renewable sources has resulted in the installation of over 10,500 MW of installed capacity. At present, with high electricity prices, stimulated by the costs of CO2 emissions and the costs of fuel purchase, renewable energy sources are of particular importance in the transformation of the Polish power industry. The RES auction system and the My Electricity Program contributed to the growth of entrepreneurship and the development of the economy. Energy consumers, from passive ones, have become active market participants—prosumers. The RES auction system alone contributed to the creation of approx. 5 GWp of installed capacity of photovoltaics (PV) sources in 2016–2021, while the My Electricity Program contributed to the creation of approx. 2 GWp of installed capacity in PV installations in 2019–2021. The aim of the study is to compare the economic and social costs of two photovoltaic development programs, My Electricity and the RES auction system, from the point of view of the country (in support distribution costs—subsidies) and investors, renewable energy installations operators and prosumers to which these programs are targeted, namely, individuals and enterprises.

Environmental sustainability and fairness in auction systems are becoming increasingly important as systems evolve with the integration of digital technologies. This paper introduces a novel demand-supply matchmaking (DSM) framework designed to improve fairness and sustainability in auction environments, aligning with the principles of the circular economy. The framework addresses key challenges in supply chain management, such as equitable resource distribution and the reduction of environmental footprints. The framework integrates key aspects of environmental impact assessments, fairness assessments, and behavioral analytics. This enables the simulation of bidder behavior and assessment of auction scenarios. Our simulation results demonstrate that the platform can promote sustainable, fair, and informed auction practices. By comparing our approach with existing tools, we highlight the advantages of using the DSM framework to improve sustainability and fairness in digital marketplaces. This work supports the development of platforms that integrate economic efficiency with environmental responsibility and social equity.

Abstract The social structure of inland fisheries communities tends to place powerful elites in important positions, while local fishermen are subordinate actors. Patronage is a form of social relationship that describes the unequal social structure between these actors. This research aimed to analyze social structure in the inland waters of South Sumatra in the practice of the Lebak Lebung and River Auction (L3S) in OKI District. To achieve this goal, a constructivist paradigm with qualitative research methods was employed, and the sample comprised 39 informants selected as subjects. The data analysis was conducted in three distinct stages, namely data reduction, presentation, and drawing conclusions. The results showed that the regulation of open access for all parties in the local government regime after 1982 created an institutionalized social relations structure where the government, investors, traders, middlemen, and non-fishing actors dominated compared to the fishermen. The participants in this social landscape strived to accumulate capital to enhance their competitiveness within the L3S domain. A patronage system was implemented with middlemen assuming the role of patron and the fishermen acting as their clients. The current institutional social structure has created an unfair distribution of resource benefits for fishing workers. The novelty theories were found in the working relations of the inland waters community of South Sumatra, namely stratified distribution of rights, dual status, multi-stage patronage, and the positive function of patronage for chief fisherman. Further research should be conducted to research policy revitalization and develop strategic inland water management models. Highlight Research The author mentioned 3 highlights from their results research: Auction system in inland waters in South Sumatra presents an unfair distribution for fishermen. Structure of the working relationship formed is an asymmetric patron-client relationship but with novel theories such as the stratified distribution of rights model, dual status, multi-stage patronage, and the positive function of patronage. An imbalance in local access to auction objects due to their weak ability to accumulate capital.

Due to the high maintenance cost of traditional online auction system, poor load balance ability and down problems occurring in the peak value of system access, this paper aims to propose a solution to transit from traditional online auction system to cloud computing to get higher work efficiency, lower expenditure and less energy cost. The GAE platform is used to deploy application of the overall framework of online auction system in cloud computing, including development environment as well as online auction system components, and software architecture. The online auction negotiation algorithms in cloud computing are also proposed. Based on these key technologies, the business processes of the online auction system in cloud computing is designed, including users' login system, starting an auction, bidding processes, online auction data storage, and logout system. The online auction system constructed on GAE platform with cloud computing resources and storage ability can reduce the pressure of terminal equipment, which is more robust than traditional online auction system facing users' changeable needs in the process of online auction.

This report summarizes the results of a recent review of the emerging experience with the design and implementation of policy instruments to promote the development of renewable energy (RE) in a sample of six representative developing countries and transition economies ('developing countries') (World Bank 2010). The review focused mainly on price- and quantity-setting policies, but it also covered fiscal and financial incentives, as well as relevant market facilitation measures. The lessons learned were taken from the rapidly growing literature and reports that analyze and discuss RE policy instruments in the context of different types of power market structures. The analysis considered all types of grid-connected RE options except large hydropower: wind (on-shore and off-shore), solar (photovoltaic and concentrated solar power), small hydropower (SHP) (with capacities below 30 megawatts), biomass, bioelectricity (cogeneration), landfill gas, and geothermal. The six countries selected for the review included Brazil, India, Indonesia, Nicaragua, Sri Lanka, and Turkey.

In modern times, people have paid more attention to their private information. The data confidentiality is very important in many economic aspects. In this paper, we proposed a secure auction system, in which the bids will not be revealed, and no one can fake the winning identity and the winner cannot change the winning bid. The communication cost of our scheme is low; only two rounds communication are needed between the bidders and the auctioneer. And we show that our scheme achieves the desired security requirements.

This report assesses the potential of electricity contract auctions as a procurement option for the World Bank's client countries. It focuses on the role of auctions of electricity contracts designed to expand and retain existing generation capacity. It is not meant to be a 'how-to' manual. Rather, it highlights some major issues and options that need to be taken into account when a country considers moving towards competitive electricity procurement through the introduction of electricity auctions. Auctions have played an important role in the effort to match supply and demand. Ever since the 1990s, the use of long-term contract auctions to procure new generation capacity, notably from private sector suppliers, has garnered increased affection from investors, governments, and multilateral agencies in general, as a means to achieve a competitive and transparent procurement process while providing certainty of supply for the medium to long term. However, the liberalization of electricity markets and the move from single-buyer procurement models increased the nature of the challenge facing system planners in their efforts to ensure an adequate and secure supply of electricity in the future at the best price. While auctions as general propositions are a means to match supply with demand in a cost-effective manner, they can also be and have been used to meet a variety of goals.

Public corporations of Korea may opt for either online auction or offline issue of bonds, the latter being a more traditional method using investment banks. These two methods have distinct advantages and disadvantages. Corporations that adopt the online issue method tend to have lower earnings management, use more conservative accounting, and enjoy superior scores on the government's assessment of management performance. This means that corporations that choose online, the more transparent issuance method, are more transparent in their accounting practices.

European gas markets have gone through profound restructuring processes in the last 20 years. Directive 98/30/EC represented the first attempt to liberalize this market through the unbundling of gas supply and generation from the operation of transmission networks. The goal of this Directive was the creation of an internal market for gas by breaking up vertically integrated national companies. This commitment to integrate the European gas market was strengthened by Directive 2003/55/EC few years later and then confirmed by the Gas Target Model in 2011. This progressively increasing competition of the European gas market implies significant changes in the pricing system. In particular, it has been envisaged that long-term contracts, traditionally used to trade gas in Europe, could be partially substituted by short-term transactions operated in (liquid) spot markets, possibly organized as implicit auctions. Considering this framework, we investigate the problem of managing a dynamic system of spatially distributed spot markets where gas is traded on an auction basis. These markets are cleared taking into account transmissions, balance, and storage constraints. We propose a set of equilibrium type conditions for this system of markets and show that it is equivalent to a single-level variational inequality problem. In order to find its solution, which yields an equilibrium trajectory, we apply a dual type method. Numerical experiments are conducted on the gas spot markets developed in the Netherlands and in the United Kingdom.

In the digital economy, electronic auction systems are becoming more prevalent in facilitating the transactions between buyers and sellers. Auction websites, such as eBay and Amazon, as well as more sophisticated platforms, such as Moai and FrictionlessCommerce have increased transaction volume by offering tailored auction protocols to specific customer groups. meet2trade is a generic electronic market platform that supports various auction mechanisms. This study examines the impact of a discount in a second-price, sealed-bid mechanism on bidding behavior and market outcomes. Emphasis is thereby placed on bidders’ system-based perceptions, beliefs about usage and institutional-based trust, and intention to use such an auction. Ninety students were recruited to participate in an experiment held at a Western European university. The experiment observed user behavior in second-price auctions with and without a discount. The results demonstrate that although discounts do affect bidding behavior and economic outcomes, they do not influence bidder’s intentions to use such auction mechanisms. Instead, we found that intention to use is influenced by institutional and usage beliefs that are shaped by system-based perceptions, which in turn provide specific advice to market engineers on the technical aspects influencing system adoption.
