This paper empirically investigates to what extent environmental education (EE) at school can explain variation in environmental literacy of 15-year-olds in Colombia, while controlling for several other student-and school-level confounding factors. We use a two-level nested model, where the individual observations are nested within schools. Based on the maximum likelihood estimation method, we estimate a linear mixed model which contains both fixed effects and random effects. Our empirical results only provide weak evidence that environmental education can promote a higher level of environmental awareness. The relationship between environmental education and awareness of renewable energy technologies (RETs) is even weaker. Our findings therefore suggest that environmental education should not be considered a magic bullet in promoting environmental literacy among students. Additionally, we find more reliable predictors for environmental awareness than for awareness of RETs. Overall, the socio-economic status, stronger student science abilities, parent characteristics, and a few school-level characteristics such as quality of education resources and school ownership (public versus private) seem to be decisive factors for varying levels of environmental literacy among students in Colombia.
This study is part of an emerging literature that aims to shed light on China's development finance activities in Africa using quantitative estimation techniques. This paper empirically investigates whether African authoritarian regimes receive more Chinese development assistance than democratic ones, both in absolute and relative terms. I use three different measures of democracy/autocracy which allows me to check whether my results depend on the specific indicator chosen. The OLS results suggest that Chinese development finance does not systematically flow to more authoritarian countries, controlling for strategic, economic, political, institutional and geographic confounding factors. The results are not driven by the specific democracy indicator used in the analysis. The findings remain virtually unchanged if I reduce the sample to Sub-Saharan Africa only. Furthermore, the results stand up to several robustness checks, including FE, RE and instrumental variable estimation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
