This paper explores some Sustainable Development Goals (SDGs – 2 and 12) in agriculture for the Czech Republic and Ukraine. The idea is to find out best practices in implementing SDGs 2 and 12 within the responsible investment framework. For these purposes, benchmarking (comparative analysis) is used. Using data over the period of 2017–2020, a general comparative review of global and national targets of SDGs 2 and 12 in Ukraine and the Czech Republic is provided. The results justify the merely incorporation and compliance of these targets at the national and global levels. The identified problems in achieving SDG 2 and SDG 12 are common for Ukraine and the Czech Republic and relate to unequal access to investment and financial resources. Recommendations and solutions to the most important problems based on the responsible investment instruments are proposed in this paper. The research findings can be useful for regulators (both in agriculture and in the financial market), companies and a wide group of other stakeholders in promoting responsible investment to make more comprehensive progress towards SDG 2 and 12 in Czech Republic and Ukraine by 2030.

This paper explores price effects caused by the expiration of derivatives in the cryptocurrency market. Applying different statistical tests (ANOVA, Mann–Whitney, and t-tests) and econometric methods (the modified cumulative abnormal return approach, regression analysis with dummy variables, and the trading simulation approach) to daily and weekly Bitcoin data over the period 2018–2021, the following hypotheses are tested: (H1) Expiration days create patterns in price behavior in the cryptocurrency market; and (H2) Price patterns can be exploited to generate abnormal profits from trading. The results suggest that expiration effects are only nominally present in the cryptocurrency market. There are differences in returns between expiration-related periods and average returns, but these differences are statistically insignificant. The only case in which an anomaly was detected was related to abnormally high returns during the week of expiration: returns during such weeks were positive in 65% of cases, and were on average 5 times higher than during usual weeks. Trading strategies based on this fact were able to generate results different from those of random trading, with a Sharpe ratio above 1. This is evidence in favor of the existence of a real price anomaly, which contradicts the efficient market hypothesis, and this could be implemented in the practice of traders and investors by creating trading strategies based on detected price effects or special technical analysis indicators to generate trading signals. For academics, these results might provide an opportunity to improve time series forecasting analysis in the case of Bitcoin.

This paper examines momentum and contrarian effects in the Ukrainian stock market after one-day abnormal returns. To do this, UX futures data over the period 2010–2018 are used. The following hypotheses are tested: H1) hourly returns on overreaction days differ from hourly returns on normal days, H2) there are price patterns on overreaction days, and H3) to test these hypotheses, visual inspection and average analysis are used, as well as t-tests, cumulative abnormal returns, and trading simulation approaches. The results suggest that there are statistically significant differences between intraday dynamics during the usual days and the overreactions day. There is a strong momentum effect present on the day of overreaction: prices tend to change only in the direction of the overreaction during the whole day. The fact of the overreaction becomes clear after 13:00-14:00. This gives a lot of time to explore the momentum effect in the day of overreaction. On the day after the overreaction, prices tend to go in the opposite direction: contrarian pattern is detected, which is in line with the overreaction hypothesis. Based on detected price patterns, rules of trading and trading strategies for the Ukrainian stock market are developed. Momentum Strategy (based on price patterns on the day of overreaction) generates several successful trades; close to with 90%, and their number being is profitable (trading results differ from the random ones – confirmed by t-tests). Contrarian Strategy (based on price patterns on the day after the overreaction) demonstrates low efficiency, and results do not differ from random trading.

The purpose of the article is to comprehensively define and generalize the essence of the concept of sustainable development, the basic principles of the concept, to identify the features of the strategy of sustainable development of Ukraine’s economy in terms of European integration. Research methodology. The methodology of the system-complex approach concerning consideration of the concept of sustainable development as a single whole from three components is offered: ecology, social and economic problems. Scientific novelty lies in the substantiation that the guarantee of successful sustainable development of Ukraine is to ensure economic growth, increase social welfare and environmental security. It is stated that the concept of sustainable development appeared in the 80s of the twentieth century. in the framework of the International Commission on Environment and Development. Analyzing, systematizing and generalizing scientific definitions of many scientists, the essence of the concept of “sustainable development” is investigated and its definition is specified. It is determined that the process of state building on the basis of coordination and harmonization of social, economic and ecological components in order to meet the needs of present and future generations is a sustainable development. The main approaches to the interpretation of sustainable development are highlighted and it is indicated that the quality of life of people and the state of society are influenced by a combination of economic, social and environmental factors. It is stated that the most common in the scientific economic literature are the principles of sustainable development such as environmental protection; improving the social sphere; balance of technological and economic development. The purposes and features of formation of model of sustainable development of economy of Ukraine are covered. It is stated that the national objectives, indicators for monitoring the implementation of tasks and targets for achievement by 2030 are reflected in the National Report “Sustainable Development Goals: Ukraine”. The goals of sustainable development of Ukraine are given. Schematization of the model of balanced development of Ukraine-2030 of sustainable development of Ukraine is carried out. Tasks for the Ukrainian government in the short and long term are highlighted. Relevant conclusions have been made regarding the prospects for further sustainable development. Conclusions. According to the results of the study, it is concluded that modernity is constantly making changes to the understanding of sustainable development of Ukraine’s economy. Today, sustainable development should be understood as the process of state building on the basis of coordination and harmonization of social, economic and environmental components in order to meet the needs of present and future generations. Keywords: Ukraine’s economy, economic development, sustainable development, the concept of sustainable development, goals and principles, model of sustainable development, eurointegration.
