South Africa, like most developing nations, is confronted with choosing between the need to advance their economy and the need to protect the environment. The United Nations Sustainable Development Goals (UN-SDGs-7, 11, 12 & 13) provide a strong foundation for this investigation. To this end, the current research investigates the combined impacts of economic policy uncertainty, fiscal decentralization, and green innovation on environmental sustainability for the instance of South Africa with yearly frequency data from 1960 to 2020.

Abstract

We compared different econometric specifications to model the use of medical services in Chile, focussing on visits to general practitioners and specialist physicians. The evaluated models are the Poisson, Negative Binomial, Zero Inflated Poisson and Negative Binomial, two-step Hurdle model, sample-selection Poisson, and Latent Class model.

Climate change will impose high costs on different societal actors, including firms and organizations, forcing them to adapt to this new situation. Although the relevance of implementing adaptation strategies is widely recognized, studies on firms' adaptation to climate change are still in their infancy, especially regarding small and medium enterprises.

Uniform regional development is a challenge in low-income and emerging countries, making the role of financial systems to promote new business, investment, entrepreneurship, and growth particularly important. This paper investigates the combined effect of dependence on external funding and financial depth at a regional level, estimating a panel model using Chilean data. This study reveals evidence of a direct relationship between entrepreneurship and the combined effect of the two variables.
