The aviation sector is one of the largest sources of greenhouse gas emissions, and the European Union (EU) is calling for a rapid transition to sustainable aviation fuels (SAFs). This study aims to assess market dynamics and regulatory challenges of sustainable aviation fuels (SAFs) in the European Union, with emphasis on economic feasibility and the role of policy frameworks. Using econometric methods: Autoregressive Integrated Moving Average (ARIMA) and Vector Autoregression (VAR) models, forecasts of SAF infrastructure development trajectories were produced, while regression analysis was applied to assess the relationship between national GDP and the scale of SAF deployment.

This study examines how gender equality contributes to inclusive and sustainable green transitions across the European Union (EU). Using macro-panel data for 27 EU countries, it applies three econometric models to assess how changes in gender inequality, measured by the Gender Inequality Index (GII), influence female employment, women's tertiary education as well as the performance of the environmental goods and services sector.

The chambers of agriculture play a crucial role in shaping agricultural policy, supporting rural development, and representing the interests of farmers and agribusinesses in rural areas. This research provides a comparative analysis of the Chambers of agriculture in Lithuania, Latvia, and Estonia, focusing on their historical development, governance structures, legal frameworks, membership principles, and relationships with public authorities.

Despite being the EU’s largest budgetary instrument, direct payments remain allocated through political compromise rather than clear methodological criteria, sustaining long-standing disparities between EU-15, EU-10 member states, undermining solidarity. This paper proposes 18 models based on transparent rules to address this ambivalent situation.

The public sector is perceived as a cornerstone of societal growth and development, innovation, social inclusion, and economic progress. Ensuring an environment that supports these key aspects requires effective governance, transparency, and investments, including investments in education. The role of the public sector should include providing high-quality and accessible higher education, which significantly influences students’ entrepreneurial motivation.

The European Union air transport sector has been repeatedly exposed to major disruptions such as the 2008 financial crisis, the COVID-19 pandemic, the war in Ukraine, and volatile energy prices. Strengthening resilience has, therefore, become a strategic priority. This study examines how strategic energy investments—covering renewable energy, sustainable aviation fuels (SAFs), electrification, hydrogen technologies, and advanced infrastructure—contribute to the resilience of the EU air transport system. The methodology integrates both primary and secondary data from EU policy documents, ICAO and IATA databases, Eurostat, and national statistics. A multi-criteria evaluation was applied using four key performance indicators: emission reduction efficiency (ER), annual exposure index (AEI), investment performance index (IPI), and net present value (NPV).

This study explores how sustainable culinary tourism fosters rural diversification and resilience in the Baltic Sea Region (BSR). Despite increasing recognition of gastronomy as a driver of sustainable tourism, comparative analyses across macro-regional contexts remain limited. The paper addresses this gap through a qualitative comparative analysis of twelve thematic culinary trails involving seventy-three small and medium-sized enterprises (SMEs) developed under the INTERREG Baltic Sea Region Programme’s BASCIL project.

Forecasting hotel occupancy during external shocks is particularly challenging due to their disruptive effects. This study develops a forecasting framework that integrates multisource data using a time-varying parameter state-space model (TVP-SSM). In this framework, search engine data (SED) are used to construct exogenous variables, intervention variables are used to reflect the severity of external shocks, and holiday and weekend dummy variables are used to capture the seasonal effect.

Object of research: the development and assessment of the European Union’s airport sector under economic globalization. This study conducts a comprehensive analysis of economic globalization theories, examining the key drivers of globalization, their effects on various economic sectors, and their specific linkages to transportation infrastructure. Considering the European Union’s economic policies and transport sector development strategies, the study evaluates the existing assessment tools used to measure economic globalization in the airport sector. The research provides an in-depth examination of the effects of specific globalization processes – economic integration, capital mobility, trade liberalization, and digitalization – on the European Union’s airport sector. To empirically assess the impact of globalization conditions on airport operations, a comparative analysis of the development of major EU airports has been conducted.

The study aims to evaluate the role of support in shaping farms’ investment and efficiency in Lithuania. Data from Lithuanian Farm Accountancy Data Network dataset and logistic regression was used to evaluate to what extent Lithuanian farms’ investment is affected by support and other factors. Data Envelopment Analysis was applied to compare the technical efficiency of Lithuanian farms with and without investment support. Study period was 2009-2019.
