Q51 - Valuation of Environmental EffectsReturn

In the empirical determination of the factors influencing the clean energy transition, the BRICS economies have initiated various policy reforms, such as increased R&D budgets, improvements in technology and political stability. This study analyses the critical role of political risk and economic growth, natural resources, research and development and technological innovation in the clean energy transition in the period 1990-2022. Using panel econometric approaches, this study confirms the heterogeneity of slopes and cross-sectional dependence. Using linear regression with the heteroscedastic panel-corrected standard error approach, the results show that economic expansion, political risk and the quadratic R&D term significantly enhance the clean energy transition. However, natural resources, conventional technological innovation and research and development expenditures are the leading barriers to a clean energy transition in the region. The robustness of these results is validated by a series of panel regressions. Following the empirical outcomes, this study recommends rapid enhancement of the research and development budget, strengthening of governance and institutions and investment in technological innovation to attain a sustainable transition towards clean energy sources.

This study examines the impact of monetary developments on environmental quality and economic growth. We utilize ARDL/PMG models to study twelve climatically vulnerable countries from 1996 to 2018. We find that a 1% increase in real GDP and domestic credit harms the environment by 0.827% and 0.220%, respectively. However, savings improve environmental excellence by 0.373%. A 1% environmental degradation decreases human health by 0.317%; consequently, economic growth declines by 1.102%. Good governance emerges as a key solution, with a 1% improvement in public institutions mitigating the adverse impact of real GDP on the environment by 0.777%. Redirecting 1% of loans to eco-friendly projects improves the environment by 1.311%. Dumitrescu-Hurlin and PVAR Granger tests support these findings.

Our study investigates the benefits that the Czech inhabitants could gain from the reduction of road traffic noise. We applied contingent valuation study in order to estimate willingness-to-pay (WTP) for the reduction of traffic noise by 10 dB (from 70 dB up 60 dB). Using data from 2010 Czech representative survey (n=2,104), we estimated mean WTP by nonparametric method which was based on the Kaplan-Meier estimate. Further, we explained the variability of WTP using Double-Hurdle model. In the first step, the Probit model explained the choice of individuals that are willing to participate on the program decreasing the road noise. In the second step, the log-normal regression model explained the variability of WTP on the socio-economic characteristics of individuals and characteristics of noise in the area where people live.

Brownfields are old, unused sites and buildings located in urban areas and open countryside. This article deals with problems of brownfields that developed as a result of restructuring national industry, a decreased significance of primary and secondary industry, and the increase of tertiary industry. The main part of the article provides a complex evaluation of the costs and benefits connected with brownfields regeneration in comparison with building on greenfields. The presented model evaluates both alternatives from the municipality, investor and public interest points of view. In a conclusion, there is given a recommended procedure for brownfields regeneration. The first step is to create a database of brownfields which will be later followed by the evaluation of identified brownfields according to attractiveness for investors, usability of individual brownfields from the point of view of land use planning and also the search of financial resources for regeneration and evaluation of economic efficiency of brownfields revitalization.
