Double Auction
A double auction is a process of buying and selling goods when potential buyers submit their bids and potential sellers simultaneously submit their ask prices to an auctioneer, and then an auctioneer chooses some price p that clears the market: all the sellers who asked less than p sell and all buyers who bid more than p buy at this price p. Buyers and sellers that bid or ask for exactly p are also included. As well as their direct interest, double auctions are reminiscent of Walrasian auction and have been used as a tool to study the determination of prices in ordinary markets. A simple example of a double auction is a bilateral trade scenario, in which there is a single seller who values his product as S (e.g. the cost of producing the product), and a single buyer who values that product as B.

Supply Chain Concentration and Corporate Environmental Responsibility
With the recent intensification of environmental problems such as the depletion of natural resources, air pollution, water pollution and shortage, and soil erosion, the balance between environmental protection and economic development has attracted worldwide attention, and both green economy and sustainable development have gradually become the future economic development directions of all countries in the world. The COVID-19 virus spread throughout the world since its discovery in late 2019. Many experts show that poor ecological environment is an important factor that affects the generation and spread of virus and the increasing mortality rates, hence stressing the importance and urgency of environmental protection. As micro-entities of national economic operation, enterprises are also subjects of natural resource consumption and ecological pollution and have an undeniable responsibility toward environmental protection. Improving the ecological environment should ultimately be integrated into the corporate environmental responsibility (CER) of firms.

Circular Economy and Circular Cities
An alternative way to the current way cities develops and operate is provided by the circular economy (CE). The idea of circular economy finds its roots in environmental and ecological economics, industrial ecology and management and corporate sustainability. The circular city represents a relatively new concept, and as a result, assumptions about these types of cities are often incorrect and require further explanations to understand their way of functioning. A framework for a circular economy not only reduces the raw materials used within the system but also brings opportunities for sustainable consumption, waste management and innovation in all fields, as well as human development and increased well-being for everyone. However, the nature of circular systems mandates for the collective effort of governments, businesses and consumers likewise. Therefore, a circular economy should be an integrated part of the cities’ and regions’ development plans for achieving healthy circular ecosystems.

Electricity Price and Quantity Uncertainty
Electricity is usually traded in a short-term market (spot market) and a long-term market via contracts for future delivery (forward contracts). The electricity market is characterized by being highly volatile when compared to other commodity markets. This high volatility in terms of price and quantity is due to market circumstances (e.g., expectations or strategies of each company and economic dynamics) and physical conditions (e.g., climate, water availability, fuel production, or damage to the power transmission network).
