International research collaboration (IRC) has been relevant for the development of national scientific systems. In Africa, given the limited resources devoted to research and development (R&D) activities and the crucial role that scientific knowledge generated through research activities can have in socioeconomic development, IRC may be an opportunity to strengthen scientific capabilities. While geographical, economic, political/governance, cultural, intellectual and excellence distance hampers IRC in other regions, we argue that economic and excellence distances actuate differently in Africa. We explored the impact of the variables above in addition to the information and communication technologies (ICTs), and social distances on the IRC of these countries. Using panel data for 54 African economies, our results show that economic distance fosters IRC while governance and excellence distances are non-significant. Past collaborations (one out of two proxies for social distance) and speaking the same language have the highest effect on IRC, and ICTs distance the lowest. The results have implications for science policy in Africa. For instance, we argue that science policies need to be adapted to each environment as the scientific landscape in each country is unique.

Background: There is a race to innovate, develop or create hydrogen production technologies to accelerate energy transition and create a hydrogen economy. Acceptance has been used in social science literature as a lens through which to anticipate possible challenges surrounding hydrogen technologies. However, very few studies problematize perceptions and focus on the production of hydrogen. Hence, this study aims to bridge these theoretical and empirical gaps using a mixed-method approach based on semi-structured interviews (n = 7) and a questionnaire survey (n = 73) to understand stakeholders’ perceptions of hydrogen production sources through a social construction of technology lens. Results: The findings suggest a tendency to favor hydrogen produced from renewable sources and to reject hydrogen produced from non-renewable sources. All the examined groups conform to this pattern. Their perceptions are based on prior knowledge of hydrogen technologies, with participants seeking information from specialized sources or from activities promoted by their organizations. Participants anticipate that hydrogen will be generated primarily through renewable energy sources and utilized where direct electrification is unfeasible. In addition, they envisage that the hydrogen economy will enhance energy democracy through representative participation in decision-making. Nevertheless, it is acknowledged that the topic is limited to certain social groups and kept away from the public eye. Furthermore, unlike the benefits, the perception of risk appears to have no impact on perceptions’ construction. High confidence in science appears to minimize the recognition of potential risks and bolster the recognition of potential benefits. There is, however, a lot of uncertainty about the possible real impacts of the hydrogen economy. Conclusions: There appears to be a collective perspective on hydrogen production sources, indicating the existence of social representations. Nevertheless, group attitudes and backing towards hydrogen vary. The participants identify hydrogen as a matter that remained unnoticed for over a decade, despite its prominent position in the policies and economic approaches of numerous countries. The topic has been relegated to third parties. This exclusion of civil society from decision-making may justify the NGO group's critical stance towards hydrogen. Moreover, it suggests that energy democracy, which is based on information dissemination and participation, is not being achieved.

This paper aims to analyze the impact of corruption on firm innovation in Portugal, using data from the World Bank Enterprise Surveys on 1062 firms for 2019. We employ regression analysis and instrumental variables techniques to account for endogeneity in the corruption variable. Our results show that corruption fosters innovation in Portugal, regardless of the dependent variable we use to measure innovation. We have also analyzed the effect of corruption on innovation in foreign and domestic firms. While corruption boosts innovation for domestic firms, we found that the effect is not statistically significant for foreign firms. Our conclusions are of interest to policymakers, as any measure intended to fight corruption should consider its impact on firm performance. As this article shows, such an impact need not be negative. Nevertheless, if mitigating the impact of corruption is still intended, our results indicate that measures promoting foreign direct investment could help achieve this.

The rise of cryptocurrencies over the past decade has promised to challenge the dominance of fiat money systems and reshape monetary policy. However, recent developments, including market volatility and the collapse of key exchanges like FTX, have eroded public trust, raising skepticism of a feasible transition to a crypto-based monetary system. This paper explores why cryptocurrencies have not met the expectations of their proponents, particularly those who saw them as a step towards Friedrich Hayek’s vision for competitive currency issuance. While cryptocurrencies reflect some aspects of Hayek’s model, their instability—especially in Bitcoin-like assets—undermines their role as a reliable alternative to fiat money. The paper also considers how central bank independence and regulatory gaps further hinder the development of a robust cryptocurrency framework. Despite the continued relevance of Hayek’s ideas in today’s monetary landscape, the entrenched structures of modern central banks and the rise of Central Bank Digital Currencies suggest that a decentralised currency order remains unlikely in the near future.
