Educational programs need to be updated and improved, taking into account the latest legislative changes to correctly reflect the transformations of financial services markets and the evolution of the main concepts of financial science. This affects the quality of educational training, the scientific component in higher education institutions of Ukraine, and the professional competence of future practitioners and scientists. The article aims to reveal, improve the essence and formulate the definition of the concepts of the market of insurance services, insurance market, and market of insurance, taking into account the new legislation in the insurance field and achievements of financial science. The methodological basis of the research is the position of the theory of open economy, as well as the methods of system analysis. The study includes four sections: the first section provides a brief review of scientific works on the definition of the insurance market; the second section contains the analysis of Ukrainian insurance legislation regarding the insurance market; the third section presents the quantitative calculations and a new understanding of basic concepts; in the last subsection, the authors explain how the concepts of the insurance market and the market of insurance services differ, highlight the activities of the regulatory bodies of the insurance market, and show the unresolved problem of insurance guarantees in the market. The analysis points to the still unsolved problem of state guarantees of returning insurance premiums to clients if the insurer ceases insurance activity. In this regard, the expediency of creating the Insurance Guarantee Fund, which should become a participant in the insurance market, is argued. It was found that the concepts of the market of insurance services and the market of insurance are identical. The concept of the insurance market covers the market of insurance and is distinguished by the fact that there are regulatory bodies in the insurance market. Based on the provisions of the open economy theory and the analysis of behavioral aspects of market participants, the work proposes new definitions of the concepts of the market of insurance services and the insurance market.

Curricula for the speciality 072 “Finance, banking, insurance and the stock market” must be regularly updated to cover changes in current legislation and reflect the transformations of the ever-evolving banking services market. This process directly affects the quality of educational training of students – future specialists and, therefore, should be the focus of attention of scientists and educators. The article aims to reveal and improve the essence of the concept of the “market of banking services” and formulation of the generalized concept of the “market of banking services and banking metals”, considering the realities of today and legislative changes in the banking sphere. The methodological basis of the research is a systematic approach using comparative analysis, induction, deduction and generalization. The article is conditionally divided into three parts: in the first part, a review of the legislation on the definition of banking services was carried out; the second part is devoted to the analysis of banking services market participants; in the last part, a critical review of the approaches of other researchers was carried out, and new definitions of basic concepts were proposed. It was found that legislative changes regarding the composition of participants and the structure of the banking services market of Ukraine have not been fully covered and considered in the professional literature. Systematized and expanded the range of participants in the market of banking services of Ukraine, taking into account the realities of today. According to the text of the General Agreement on Trade in Services, the list of banking services is provided, and the need for implementation into Ukrainian banking legislation was argued. The definition of the concept of “banking services market” was proposed, which takes into account the behaviour and interaction of sellers and buyers of banking services, other market participants, demand and supply for banking services and metals, bank money, pricing through interest rates and commissions for carrying out banking operations.

The study analyzed the marketing of onion in Kaduna and Katsina States, Nigeria. A survey of 100 onion farmers and 200 traders in these two states was conducted in 2022. Four villages and four markets were purposively selected. Random sampling was used to select respondents using structured questionnaire alongside oral interview. The analytical tools used were descriptive statistics, marketing margin and multiple regression. Majority of the traders (71%) had marketing experience between 5 to 25 years. Analysis on marketing margin shows that the producer’s share in the price that the final consumer pays was 56%, the wholesaler receives 14% and the retailer gets 30%, while the total marketing margin in the complete distribution chain was 43%. Analysis on the effect of marketing costs on marketing margin using multiple regression reveals that commission paid to agents was significant at 1% for regional wholesalers and 5% for inter-regional wholesalers. Transportation cost had positive coefficients significant at 10% for regional wholesalers and 5% for inter-regional wholesalers. At the level of retailers, the commission and transport charges have insignificant effect and where they exhibited significant effect, they have negative t-values. The loading/un-loading cost, revenue charges and storage cost had insignificant coefficients and negative t-values. The study recommends provision of simple drying machine for processing onion into durable products, provision of efficient transport system, onion exportation to create competition, market access to reduce glut and enlightenment of market participants on joining cooperative societies for solving many of the marketing problems.

The subject of research is the theoretical and methodological foundations of business ecosystems of companies. The purpose of the article is a study of features of process of forming and development of ecosystems, and also parameters that influence on her development status in a medium-term and long-term period. The methodological basis of the article is the theoretical provisions of the innovation economy, a set of general scientific and special research methods, namely: induction and deduction, system-structural analysis and synthesis, analogy and modeling, economic and statistical method, abstract and logical method and monographic method. Results of the article. It is established that in today's rapidly changing market conditions, the formation of ecosystems by companies is a progressive direction of economic development. However, these business models should be fully connected with business, or rather, small and medium-sized businesses should form the fundamental basis of the ecosystem, the main resource of which should be human capital and information. The concentration of these components will allow a business entity to develop new and modernize existing products, thereby better meeting consumer needs and, as a result, introducing the next stages of innovative development of humanity. Field of application of results. The results can be used in the activities of agricultural, processing, and trading enterprises, as well as in the research and educational process of agricultural universities. Conclusions. The development of IT technologies is provoking changes in the nature of competition: in the near future, it will not be individual market participants who will compete in the market, but new business models, such as ecosystems, which are able to fully meet the needs and expectations of consumers. Given the current trends in the international business environment, it is easy to predict that in the future, individual economic actors will not be able to maintain a leading position in any market segment and that they will be replaced by business models that are able to focus their efforts not only on the production of competitive products. Given recent events, the level of corruption, the share of the shadow economy, and the dynamics of macro-financial indicators, it is safe to assume that the country will continue to experience a decline in economic activity. In such circumstances, it is appropriate to look for new approaches to stimulate business.

High volatility renewable penetration increases the security risk of the market participants. In order to ensure the security of the reserve market under uncertainties, the authors have proposed a novel optimal bidding strategy based on bivariate pair copula-based security-constrained unit commitment economic dispatch (SCUCED) for the generation companies (GENCOs) while considering the volatility of wind power generations and load variations under different (N − k) contingencies in ancillary service market. The expected profit of GENCOs are based on the ramp-up and ramp-down optimal reserve curves in each time interval are submitted to the independent system operator. The profit of wind farms is obtained and the risks due to uncertainties with wind farms are also analysed while participating in the reserve market. Conditional value-at-risk is considered for the optimal placement of wind farms in the network. The risk-based SCUCED model is solved by mixed integer linear programming. Moreover, a factor called joint Pareto tail factor has been also developed to provide information regarding the fat tails in the lower end of the bivariate marginal distribution of different GENCOs. The effectiveness of the proposed approach has been tested on a modified IEEE 30 bus system. [ABSTRACT FROM AUTHOR]

Deregulation exposes the inherent volatility of the electricity price. Accurate electricity price forecasting (EPF) could help the market participants to hedge against the price movements and maximise their profits. The existing methods have limited capability of integrating other external factors into the forecasting model, such as weather, electricity consumption and natural gas price. This study proposes a deep recurrent neural network (DRNN) method to forecast day-ahead electricity price in a deregulated electricity market to explore the complex dependence structure of the multivariate EPF model. The proposed method can learn the indirect relationship between electricity price and external factors through its efficient diverse function and multi-layer structure. The effectiveness of the method is validated using data from the New England electricity market. Compared with the up-to-date techniques, the proposed DRNN outperforms the single support vector machine (SVM) by 29.71%, and the improved hybrid SVM network by 21.04% in terms of mean absolute percentage error.

Recently, power system operators have initiated procurement of a new service in electricity markets named flexible ramping product (FRP). With the main goal of enhancing the grid flexibility, this product can provide a remarkable opportunity for an enhanced short-term profitability. Energy storage systems (ESSs) with high ramping capability can leverage their profitability when properly participating in this market. This study introduces a stochastic optimisation framework for participation of ESSs in the FRP market. The proposed model formulates the optimal bidding strategy of ESSs considering the real-time energy, flexible ramp-up and ramp-down marginal price signals and the associated uncertainties. In addition, as the market participants cannot directly submit bids for the FRP, the corresponding energy bidding adjustments required to award the proper FRP amounts are elaborated. The mathematical model is linearised and its application in real-time market is investigated. The proposed framework is numerically analysed through which its effectiveness on enhancing the ESS profitability in the real-time electricity markets is verified. [ABSTRACT FROM AUTHOR]

Virtual power plant (VPP) has become a promising technique to facilitate distributed energy resources (DERs) to participate in the power markets. Considering the respective interests of the VPP agent and distribution system operator (DSO), a bi-level optimisation model for VPP bidding in multiple retail markets (including active power, reactive power and spinning reserve market) as price-maker is formulated. In the upper layer, taking into account various DERs, the VPP agent aims to develop hourly bidding prices and quantities of multiple market commodities to maximise its operation profits. In the lower layer, DSO conducts the retail market clearing to minimise the system operation cost considering the network constraints and bidding plans of the market participants. Moreover, the quadratic coupling constraints among different market commodities due to capacity limitation of distributed generators and branches are formulated explicitly in the proposed model. The hybrid simulated annealing-genetic algorithm with self-adaptive parameters is adopted to cope with the non-linearity and compute the economic bidding plans for VPP. The effectiveness of the proposed approach is verified under different scenarios through case studies, which indicate its superiority and great potential for implementation. [ABSTRACT FROM AUTHOR]

The article discusses historic and present day approaches to the concept of fair value from the point of view of IFRS 13 provisions. History of the fair value development shows the continuous extension of its use in overseas countries. This trend is also observed today. The authors analyze problems connected with defining and methodology of calculating the fair value, investigate theoretical and practical issues dealing with establishing this type of assessment and offer ideas about the use of fair value in Russia. They show obstacles to using this assessment and its advantages and disadvantages. The possibility to use fair value for all entities of accounting is considered.

The Chicago Mercantile Exchange introduced a futures contract for distillers' dried grains (DDGs) in early 2010, but the market became inactive only four months after its inception. While many new futures contracts do not develop into high-volume traders, interest from DDG cash market participants indicated that this contract could be successful. Prompted by the unexpected lack of trading activity in this new futures market, we empirically revisit the question of what factors contribute to a futures contract's success and extend the literature by investigating the roles of market participants and the significance of supporting futures markets. Estimation results indicate that the market participant type-hedger or speculator-affects futures contract trade volume. More importantly, we find that the viability of new futures contracts for commodities that are jointly produced with other commodities is impacted by hedgers' trade volume of the related futures contract. These results provide important additions into the portfolio of indicators used by commodity exchanges to more cost-effectively evaluate new futures contract products. [ABSTRACT FROM AUTHOR]

Load and price forecasting are two key issues for market participants and system operators in electricity markets. Most existing works predict load and price separately. However, a dynamic pricing type scenario is envisioned in smart grid, where consumers may have the ability to react to constantly changing price signals by shifting electricity usages from expensive hours to others, which would consequently impact electricity prices. Thus, price and load signals are strongly coupled, and previous separated forecast models may not be as effective. In this study, a two‐stage integrated price and load forecasting framework is developed. The first stage provides initial price and load forecasts separately, and the second stage considers load and price interaction with initial forecasts as inputs. At each stage, a hybrid time‐series and adaptive wavelet neural network (AWNN) model is used, in which multivariate autoregressive integrated moving average catches the linear relationship of price and load log return series, generalised autoregressive conditional heteroscedastic unveils heteroscedastic character of residuals and AWNN presents non‐linear impacts. Several criteria such as average mean absolute percentage error and error variance are used to measure the forecasting accuracy. Illustrative forecasting examples of the New York Independent System Operator market are presented to show the efficiency of the proposed method. [ABSTRACT FROM AUTHOR]

Abstract: Environment friendly policies and emission pricing schemes necessitate the integration of more and more renewable power into electricity grids. However, generation entry and transmission network development in a deregulated market depends on the cost and benefit of a project, where the system/market operator eventually decides the feasibility of investment. In this process, the priorities of market participants are overlooked in some cases. This paper investigates the preferences of market participants in evaluating renewable generation entry to the Australian National Electricity Market (NEM). The priorities of market participants have been investigated through a Multi-Attribute Decision Making (MADM) approach. The TOPSIS (Technique for Order Performance by Similarity to Ideal Solution) algorithm is used to rank the preferences. Optimal Power Flow (OPF) and economic optimization of the Queensland network of the Australian NEM have been simulated in PSS/E and the MATLAB/MatPower software platform. Simulation studies confirm that in the current scenario, gas fired power plants near to the grid will lead in the generation portfolio due to their low lead time, lower investment and dispatchability. Remotely located wind and geothermal power would only be competitive with the existing LRET (Large scale Renewable Energy Target) payments along with very high carbon emission prices.

In a competitive electricity market, short‐term electricity price forecasting are very important for market participants. Electricity price is a very complex signal as a result of its non‐linearity, non‐stationarity and time‐variant behaviour. This study presents a new approach to short‐term electricity price forecasting. The proposed method is derived by integrating the kernel principal component analysis (KPCA) method with the local informative vector machine (IVM), which can be derived by combining the IVM with the local regression method. IVM is a practical probabilistic alternative to the popular support vector machine. Local prediction makes use of similar historical data patterns in the reconstructed space to train the regression algorithm. In the proposed method, KPCA is used to extract features of the inputs and obtain kernel principal components for constructing the phase space of the time series of the inputs. Then local IVM is employed to solve the price forecasting problem. The proposed method is evaluated using real‐world dataset. The results show that the proposed method can improve the price forecasting accuracy and provides a much better prediction performance in comparison with other 12 recently published approaches.

This paper discusses the value of price forecasting in the electricity market during bidding or hedging against volatility. When bidding in a pool system, the market participants are requested to express their bids in terms of prices and quantities. Since the bids are accepted in order of increasing price until the total demand is met, a company that is able to forecast the pool price can adjust its own price/production schedule depending on hourly pool prices and its own production costs. This paper also discusses the challenges of price forecasting and describes some of the proposed methods for meeting these challenges. [ABSTRACT FROM PUBLISHER]

To successfully monitor power market operations and anticipate how market changes could affect the exercise of market power, indices of market power that are grounded in theory, reliable and easily calculated are needed. In this article, we present an index that we have found particularly useful in California: the Residual Supply Index (RSI). We demonstrate the empirical relationship between RSI and the mark-up of prices above competitive levels. We also describe two applications of this new index: using RSI to assess the overall competitiveness of the market during three years of dramatic changes in underlying structure, and estimating the benefits of increasing market competitiveness by upgrading Path 15. We also present some questions that market designers must consider when deciding how to mitigate market power when it is detected. [ABSTRACT FROM PUBLISHER]

The new proposal for regulating the European Internal Market for Electricity (EIME) can motivate the harmonization of the various National markets. The process of harmonizing the day‐ahead markets (DAMs) is at an advanced stage, with an efficiency in the use of interconnectors of 86%. However, the harmonization of both intraday (IDMs) and balancing markets (BMs) is still in its infancy, with an efficiency in the use of interconnectors of 50 and 19%, respectively. The new proposal brings new targets to DAMs, and European countries should make efforts to comply with them. The same is true for IDMs and BMs, but involving more ambitious targets, requiring higher efforts to be accomplished. Both the analysis of the various National markets (according to their compliance with the new proposal for regulating the EIME) and the advantages of the new proposal for key market participants (particularly, consumers, variable renewable generation, and conventional generation) are presented. The analysis indicates that the proposal contributes to a potential increase of the general welfare of market participants. However, some aspects of the proposal can negatively affect the revenue obtained from the National markets, notably for variable renewable generation and conventional generation.
