Background: The environment can play a relevant role in performance in runners. This study aimed to verify the distribution of the best European road runners across the continent, and to investigate variables related to country representatives in the European Senior outdoor top list 2019. Methods: The sample comprised 563 European runners, aged 18–48 years, ranked in the European Senior outdoor top list 2019 for distances of 10–42 km. Country-related variables were gross domestic product (GDP), competition place, population size, and sports investment. The countries were categorized as “top ten countries” or “other countries”. Binary logistic regression was used for analysis. Results: The United Kingdom showed the highest prevalence of runners in the ranking (men—17.6%; women—23.0%), followed by Spain (male ranking—12.1%) and Germany (female ranking—8.6%). For men, sports investment (OR = 1.13; CI95% = 1.03–1.28) and country GDP (OR = 0.96; CI95% = 0.93–0.98) showed an association with the chances of the athlete to reach the Top 10 ranking, while among women, the only variable significantly related was the competition venue (OR = 3.97; CI95% = 1.40–11.23). Conclusion: As in other sports considered “non-expensive”, the economic and demographic characteristics of the place where athletes train can provide advantages in performance.

This paper aims to decompose the sources of growth in economies in the Southern African region’s Common Monetary Area and in the provinces of South Africa. Decomposition results for the Common Monetary Area reveal that the growth of aggregate and sectoral gross domestic product is driven by input, without increasing efficiency in production or benefiting from technological progress, which is unsustainable. Negative technical change implies that countries are unable to reap the benefits from shifts in technology. Countries experiencing input-driven growth in the secondary sector, such as Namibia and Eswatini, have the potential to achieve growth through efficiency improvements and by adopting technology. Output growth in the provinces of South Africa is negatively contributed by changes in technical efficiency, which suggests that policy makers should raise growth further by emphasizing improvements in efficiency in these provinces.

This study examines the link between oil prices and economic activity proxied by gross domestic product in the context of South Africa. The study employs the asymmetric approach proposed by Schorderet (2004) and advanced by Lardic and Mignon (2008). Asymmetric cointegration is used because it is believed that increasing and decreasing oil prices do not have similar or equal impacts on economic activity. In this study we document evidence for an asymmetric response of economic activity to oil price shocks. Further, our findings suggest that negative oil price shocks are important relative to positive oil price shocks.
