The aspiration of this study was to examine the impact of foreign direct investments (FDI) and economic growth on environmental degradation in the Balkans for the period 1998–2019. Balkan countries were classified into two groups, high income countries (HIC) and upper-middle income countries (UMIC). Thus, two hypotheses have been set. The effect of FDI on environmental degradation was observed through pollution haven hypothesis (PHH). To examine that connection, we used Pearson correlation for all countries, HIC and UMIC. Furthermore, the impact of economic growth on environmental degradation was tested through the environmental Kuznets curve (EKC) hypothesis. For that purpose, polynomial linear regression was applied. In order to examine the dependence of environmental degradation in relation to all predictors in the model, a multivariate linear regression was used. PHH was confirmed in Serbia, Albania, Croatia, Romania, and Bulgaria, the Balkans as a whole, and HIC, and the EKC hypothesis was rejected. This paper represents a contribution to a very scarce number of studies regarding the impact of FDI and economic growth on the environment in the Balkans, as a whole. The results of this study can be useful to policy makers in the terms of inducting stricter environmental rules.

Criticisms addressed to the mechanism for resolving disputes between foreign investors and host countries, i.e. investment arbitration, have led to various proposals and attempts to find optimal reform options. Within the framework of UNCITRAL's Working Group III, since 2017 proposols from various stakeholder have been considered. This paper analyzes the main objections to the dominant investor/state dispute settlement system, as well as the most important reform options, which appear in the literature and practice of international organizations, primarily UNCITRAL. Although this process is still ongoing, it is evident that, on the one hand, there is a plurality of different interests and proposals of the main actors of international investment law, while, on the other hand, there is a wider consensus on the necessity of certain reforms in order to establish and strengthen consistency, uniformity and predictability of arbitration decisions. Certain reforms are already being implemented in practice through new investment agreements.

The aim of this study is to explore how entrepreneurs assess their self-efficacy in relation to their amount of monthly income, years of entrepreneurial experience, and job satisfaction. Moreover, the relationship between entrepreneurs’ self-efficacy and the indicators of entrepreneurial skills was explored. A total of 335 entrepreneurs aged between 25 and 64, who were mostly men (70.1%), participated in the study. The participants answered 10 questions from the pilot version of the Checklist of the Indicators of entrepreneurial skills and General Self-Efficacy (GSE). The results have shown that the amount of monthly income and job satisfaction both have a significant effect on the entrepreneurs’ assessments regarding their self-efficacy. Moreover, the results have shown that two indicators of entrepreneurial skills singled out as significant predictors of self-efficacy. The indicator “I have a hard time dealing with stressful situations at work” has a negative relationship with the entrepreneurs’ assessments self-efficacy, while the predictor “I learn from wrong business moves” has a significant and positive relationship with entrepreneurs’ assessments of self-efficacy. The relationship between self-efficacy and stress management is discussed in the context of successful and sustainable entrepreneurship. It is concluded that the entrepreneurs’ assessments of self-efficacy are “stress sensitive”, whether the challenge is imposed or defined by the social surroundings, e.g., the amount of monthly income, or the entrepreneur’s personality, e.g., job satisfaction, risk management and self-confidence.
