Transport is very important for the economy and the society because good transport infrastructure helps to improve the mobility of citizens and the traffic of goods, thus ensuring economic sustainability. Background: The European Union (hereinafter—EU) plans to maintain support for the development of transport infrastructure in individual member states. Lithuania’s role as a transit country in the EU’s transport network is of great importance; therefore, efficient transport services and appropriate infrastructure can not only support the domestic market and economic and social growth of the country, but also promote positive economic, social, and political processes in other countries and ensure EU’s strategic defence movement channels. Methods: The study was conducted using econometric methods, including correlation analysis and a regression model, to assess the selected parameters of the transport sector of Lithuania as a transit country and their impact on the real gross domestic product (hereinafter—RGDP) of the selected Baltic states (Latvia and Estonia). Results: The study identified a combination of key factors in the Lithuanian transport sector that affect differences in the level of real GDP per capita. Conclusions: The findings revealed differences in the context of relation between RGDP per capita in the three Baltic states and indicators of the Lithuanian transport sector.

As geopolitical instability increases and new threats emerge, a number of countries are increasing their respective allocations for defence expenditure in order to take greater responsibility for their citizens in terms of defending and protecting their values and way of life. Small states such as Lithuania, Latvia, and Estonia must evaluate certain economic, political, and strategic factors when increasing their respective defence expenditure. While they do tend to increase expenditure on national defence matters, budgetary constraints often force them to cut funding in some civilian domains or to increase their borrowing on international markets. Therefore, the security and defence of small states must be addressed in an integrated way, taking into account economic, social, and environmental factors. The aim of this article is to assess the relationships between defence expenditure and sustainable development indicators during the period between 2000 and 2018 in the Baltic states. The authors of this article aimed to determine which sustainable development indicators have a significant impact upon a country’s expenditure when it comes to defence matters. The study was conducted using econometric methods, including Spearman’s correlation analysis and Automatic Linear Modelling (ALM). The research results revealed some differences amongst the Baltic countries. In Lithuania, the employment rate and R&D personnel as a share of the active population demonstrated a significant impact upon defence expenditure. In Latvia, defence expenditure was found to be affected by disposable household income per capita and environmental taxes as a share of total tax revenue. In Estonia, defence expenditure was mainly influenced by disposable household income per capita and energy import dependency. The study’s findings may be used to ensure both the security of the country and the implementation of the Sustainable Development Goals.

The research conducts a systematic literature review to critically analyse the complex interrelations among perception, adoption, and investment decision-making in the cryptocurrency markets. The study synthesizes global research findings, highlighting how investor perception and adoption patterns impact investment behaviour. Additionally, the review evaluates the methodologies utilized in existing studies, providing valuable insights into their strengths and limitations. This comprehensive analysis consolidates current knowledge in understanding the mentioned interrelations, identifies key gaps in existing research as numerous aspects remain unexplored and suggests potential directions for future studies, aiming to deepen the understanding of cryptocurrency market dynamics and enhance investment strategies.

Migration, emigration and immigration are processes directly related to transport and have a significant impact on the performance of this field. On the other hand, extensive movement of people inevitably relates to issues of sustainability, their assurance, etc. Migrants settle in large cities where public transport is well developed. Migrants usually commute by means other than driving their own cars (choosing public transport, walking, cycling or car sharing). Many researchers in the USA (United States of America) have linked this to migrants’ choice of a place of residence, which are well served by public transport, as they mainly travel for work. However, with passing time and improving living standards, the need for immigrants to not only use public transport, but to also own their own, becomes similar to that of the locals. This also increases the need for the analysis of sustainable transport issues. The correlation and regression analyses used in the article and the application of the ALM (automatic linear modelling) modelling led to the following results: a significant positive correlation was found between emigration and passenger carriage by all modes of transport|Maritime transport, and a significant negative correlation was found between emigration and passenger carriage by all modes of transport|Rail transport, suggesting that these indicators have a mutually significant relationship with one another. The conducted regression analysis and applied modelling showed that the regression model was insignificant and therefore cannot be used. However, the results suggest that the relationship between immigration and transport indicators can be used as a direction for further research.

In today’s interconnected global economy, financial risk management has become a critical component of national security and sustainable development. In countries, especially small ones such as the Baltic States—Estonia, Latvia, and Lithuania—effective financial risk management is crucial to ensure the viability of the financial system, preserve economic stability, promote growth, and ensure the well-being of citizens. This section examines the importance of financial risk management in the national context, highlighting its link to sustainability and national security. It presents the theoretical and practical aspects of financial risk management, the specificities of financial instability in small countries, an overview of the main economic and financial crises affecting the Baltic States and their consequences, and a discussion of generalised resilience to financial threats.
