In this paper, we investigate the influence of airport operation on property prices. In this research, we apply spatial hedonic regression and a difference-in-differences approach to address the introduction of new land use restrictions on property prices. We use data on housing transactions from two housing submarkets around regional airports in Poland. The results suggest that the introduction of land use restrictions impacts property prices. In general, as expected, more rigid restrictions translate into higher discounts in property prices. This research contributes to the limited knowledge on the impact of the introduction of land use restrictions on property prices, as most previous papers have focused solely on the impact of noise. These findings must be treated with caution, as some estimates were not statistically significant, mainly due to limited sample size. The research has important policy implications. Growing airports in Poland face tensions between economic and environmental sustainability. Currently, airports in Poland are obliged to limit their environmental impact by creating limited use areas related to the aircraft related noise while being responsible for property value loss related to these restrictions. As a consequence, most regional airports face significant compensations to property owners.

Diverse measures related to the electrification of transport fleets have been implemented in many countries due to the increasing consumption of fossil fuels and their negative impact on the climate and human health. Such transformation is effective if electric energy is sourced from renewable sources. The rate of transport electrification is determined mainly by legislative and financial incentives, charging infrastructure density, and fuel price. The main aims of the study are to present financial support for investments in low-emission transport infrastructure and to provide forecasts of the fleet of urban electric buses and the expected demand for electricity consumed by them in Poland. The main source of data was statistical reports published by Statistics Poland. Because the available sample was short, basic statistical models were used. The results obtained indicate the stable growth of investments in regional low-emission transport infrastructure, characterized by strong heterogeneity. The foreseen number of electric buses in urban public transport in the realistic variants ranges between 1486 and 1626. In the optimistic variants, the forecast values are significantly higher. However, they can only be achieved if there is a significant increase in investment. The electricity demand forecast for the realistic variant shows a demand of 341,266.50 MWh.

The study aimed to evaluate whether the regional funds allocated for energy efficiency and renewable energy are related to the quantity of air pollutants discharged and the stage of regional development, and whether the evidence of convergence of regional levels of renewable energy electricity generation can be provided. A comparative analysis of financial instrument implementation within regional programmes was conducted, with a particular focus on instruments dedicated to enhancing energy efficiency and utilising renewable energy. To verify the research hypotheses, statistical coefficients of correlation and concentration, along with trend and econometric models were applied. The findings have confirmed the rise in regional funds for energy efficiency and renewable energy, along with the growing importance of financial instruments in transforming the energy sector. The hypotheses that air pollutant emissions per unit of GDP generated are decreasing, there exists a regional convergence of renewable energy production per capita, and the spatial accumulation of renewable energy production is declining, have been confirmed. No correlation was found between the regional economic development and the level of funds allocated to energy efficiency and renewable energy. The lack of such relationships provides a convincing argument for appropriate state regulation.

The aim of this paper is to apply the concept of marginal vertical income convergence to analyze the influence of the two last economic downturns (2007 and 2020) on the sustainability of the equalization of income levels within the European Union. The methodology used enables us to avoid some restrictions of the classical analysis of income convergence. Income convergence models were estimated using data from the period 1993–2022, excluding the impact of outliers. The results confirm that we can observe the progressive process of the absolute income convergence for EU members, but there are significant differences between countries’ contributions to the process. These differences are caused by different paths of economic growth, and different mean resilience to economic crises, as well as different patterns of income inequalities. Their proper recognition allows us to develop efficient policies aimed at social cohesion, reducing income inequalities (the 10th Sustainable Development Goal), and sustainable economic development. Additionally, the estimated models indicated a definite different impact of the last two economic shocks on the European process of income convergence. The first shock significantly slowed down the income convergence process, while the second one was practically neutral in this context.
