Food security is a major worldwide concern that has received heightened focus due to the COVID-19 pandemic, which disrupted global food supply chains and agri-food value networks. This paper seeks to determine the threshold at which food security is considered vulnerable to geopolitical shifts. Thus, using a dynamic panel threshold model on a sample of 40 countries, covering both advanced and emerging economies, this paper explores the link between food security – measured by the Global Food Security Index (GFSI) and its four key pillars (affordability, availability, quality and safety, sustainability and adaptation) and geopolitical tensions, represented by the Geopolitical Risk Index (GPRI), over the period from 2012 to 2021. The analysis also accounts for key variables such as agricultural land use, the impact of COVID-19, shares of urban population, price levels, and GDP per capita. The main findings indicate that the inflationary impact of geopolitical risk is statistically significant. A point (threshold value) of 0.022 was identified for geopolitical risk, beyond which global food security is substantially weakened due to increased inflation. The findings reveal that geopolitical risks exacerbate price surges across key commodities, including fertilizers, food, and oil, thereby amplifying inflationary pressures arising from fiscal measures taken in response to geopolitical shocks. Moreover, elevated geopolitical risks heighten uncertainty regarding the inflation outlook, complicating trade-offs between monetary and fiscal policies.

Impact of inflation on economic growth: evidence from Nigeria

Investment Management and Financial Innovations Volume 17, 2020 Issue #2 pp. 1-13 Views: 11143 Downloads: 6205 TO CITE АНОТАЦІЯIn an attempt to examine the influence of inflation on the growth prospects of the Nigerian economy, the study employs the autoregressive distributed lag on the selected variables, i.e. real gross domestic product (GDP), inflation rate, interest rate, exchange rate, degree of economy`s openness, money supply, and government consumption expenditures for the period 1980–2018. The study findings indicate that inflation and real exchange rate exert a significant negative impact on economic growth, while interest rate and money supply indicate a positive and significant impact on economic growth. Other variables in the model depict no influence on the economic growth of Nigeria. The causality result shows the unidirectional relationships between interest rate, exchange rate, government consumption expenditures and gross domestic product. However, inflation and the degree of openness show no causal relationship with gross domestic product. As a result, the study recommends that a more pragmatic effort is needed by the monetary authorities to target the inflation vigorously to prevent its adverse effect by ensuring a tolerable rate that would stimulate the economic growth of Nigeria.

Problems and Perspectives in Management Volume 19, 2021 Issue #4 pp. 458-469 Views: 7652 Downloads: 10621 TO CITE АНОТАЦІЯIn this present age of globalization, the logistics and transportation industry has become an integral part of most businesses/firms as it is aimed at ensuring the effective movement of people, distribution of goods and services from one location to another on time. Therefore, this paper aims to analyze the impact of COVID-19 on the logistics and transportation sectors. The qualitative research approach was adopted using analysis and synthesis of scientific literature, data from news reports, organizational sites, and a case study of data contents. The paper presented the analysis of negative and positive effects of COVID-19 on the logistics and transportation industry. The study also discusses possible strategies and further steps for improvement of the logistics and transportation sector, including the automation and introduction of other technologies, a sustainable and flexible transportation system, cooperation of logistics and transportation business. Findings regarding the positive implications of COVID-19 show noticeable advancements in the logistics and transportation sector, such as the rise of e-commerce businesses with efficient delivery options, and the development of 3rd party logistics services as more companies outsource supply chain operations. The study revealed the importance of strategic planning with a joint effort from the research centers, public sector, private sector, and educational institutions as one of the proposed solutions for the logistics and transportation industry.

Fair market value of bitcoin: halving effect
Artur Meynkhard
doi: http://dx.doi.org/10.21511/imfi.16(4).2019.07
Investment Management and Financial Innovations Volume 16, 2019 Issue #4 pp. 72-85 Views: 4926 Downloads: 1274 TO CITE АНОТАЦІЯThe purpose of this article is to analyze the effect that halving has on the fair market value of bitcoins. The main hypothesis of the study is that the decline in the cost of miners’ remuneration for mining is a significant factor that affects the price of cryptocurrencies. The article examines the factors that regulate the issuing process. The significance of a limited supply of bitcoin is detailed in the article, as well as the mechanism for the implementation of the issue of new bitcoins. The study compares the historical inflation data of the US dollar and the projected data on the inflation of bitcoin. The article analyzes the main technical element of cryptocurrency – halving – when the miner’s reward is halved. This analysis includes the mathematical methods of statistical data processing. Research results show that reducing remuneration by half every four years leads to an increased market value of the cryptocurrency. This relationship is clearly illustrated by the Kendall rank correlation method. The results of the study can have a significant impact on the fundamental assessment of bitcoin and can also enable investors to assess any of the existing and operating cryptocurrencies according to this method.
