The air quality effects of Uber (with Luis Sarmiento)
- Environmental policies and embodied emissions exports and imports (with Elena Verdolini and Laura Bonacorsi)
- In the absence of a global greenhouse gas reduction mechanism, the EU adopted the strongest climate mitigation policy in the world. As a result of this, there are concerns about the challenges faced by EU carbon-intensive and trade-exposed countries and industries as well as regarding the effective contribution of EU climate policies to GHG emission reductions. On the one hand, competitiveness may be harmed due to the unilateral nature of climate mitigation policy and the impact this can have on trade flows and balances. On the other hand, European demand for foreign carbon-intensive good may increase, potentially offsetting any emission reduction efforts. In this initial analysis, we assess whether and how embodied emissions in traded goods have changed over time, particularly in response to the implementation of climate mitigation policies. Our analysis provides insights both at the country level and at the sector level. We find evidence that stringent environmental policies are associated with lower exported emissions and emissions intensity, but mixed evidence on their effects on imported emissions and imported emissions intensity. Overall, we do not find conclusive evidence supporting the pollution haven hypothesis.
- Green Growth Policy Inputs and Outputs: A Machine-Aided Analysis of G-7 Countries (with Kyle Herman , Soheil Shayegh, and Jun Xiang)
- Green growth policies have been developed to co-address climate change and economic growth, and especially, to overcome the economic challenges brought by the COVID-19 pandemic. Despite being on the top of policy agenda in many countries, little quantitative analysis has been conducted on green growth policy inputs and respective economic and environmental outputs. To address this gap, we provide a classification of green growth data from the member countries of G7 group through a machine-automated K-means clustering analysis, followed by a correlation analysis with an eye on finding green growth ‘win-wins’--or environmental and economic benefits of green growth policy inputs. Our results show that environmental tax policies, at the aggregated level, are more associated with first-order energy and emission outputs and, to a lesser degree, with second-order economic productivity. However, the results vary greatly at the country level. One unexpected finding is that, despite being the most advanced economies, the G-7 countries still lack high quality, time-series data for measuring green growth policy inputs and outputs. Nevertheless, our proposed framework could be used for helping to ameliorate such data issues, to develop more robust green growth policy mixes, and to generate meaningful collaboration across countries, including for the ‘build back better’ green growth initiative recently announced by leaders of G-7 countries.
- How open are African inventors? Open green technologies and patenting activities in Africa (with Maruf Sanni)
- Open green innovation is essential to accelerate decarbonisation in Africa. The dearth of empirical evidence on the current trajectory of green innovation in Africa often hinders the design of appropriate green innovation policy. This study investigates incidence of collaboration in inventive activities within Africa using the “designation of the inventor” in the online European Patent database. Using explorative and network analysis techniques, we identify and assess open and closed climate adaptation and mitigation inventions. We find that the number of green inventions is slightly increasing, but there are very few collaborative open green inventions in Africa as many of the inventions are closed. These results accentuate the case of fragmented national innovation systems in many of the African countries. The lack of collaboration and disconnect between the universities and firms shows most knowledge institutions in Africa have not evolved into vibrant sources of firm learning for national economic development.
- Responsiveness of scientific research systems to covid-19 pandemic: an empirical study at the country-level (with Taehyun Jung)
- COVID-19, spreading rapidly worldwide since January 2020, profoundly affected all aspects of economic and social systems. The science and technology research community played a significant role in developing a scientific solution to this calamity. While the extant literature discusses how science and innovation systems can contribute to the resilient recovery of socio-ecological and regional systems, it overlooked how resilient scientific research systems are and what makes them different. Using early academic responses to the COVID-19 pandemic as an empirical setup, we examine the factors affecting the heterogeneous responsiveness among countries. After examining the issue salience, specific and related capability, and overall resources, we found that the already-established research capability in the directly relevant area increases the responsiveness. Issue salience showed mixed results. Most importantly, we found that Korea is far behind other countries, notably Italy, regarding COVID-19 research quantity and quality, indicating that something internal to each scientific research system made a bifurcation in the scientific responsiveness to the COVID-19. We conclude the paper by discussing possible mechanisms underlying this heterogeneous responsiveness from system resilience and open innovation perspectives and provide some policy implications.
- Generalisable technology-specific indicators for analysing energy technology innovation systems
- To better coordinate energy innovation efforts and to effectively mobilise resources, a systemic perspective on energy innovation is required. Traditionally, researchers have examined a quantitative cross-country analysis and a qualitative analysis of technology. For example, the National Innovation System literature has identified standardised quantitative indicators for measuring national or country performance, whereas the Technology Innovation Systems approach is strong in theory and case-study analysis using bespoke indicators. However, there is currently no generalisable set of quantitative indicators for comparatively measuring technological innovation system performance. To fill this gap, we provide generalisable and replicable indicators for measuring technological innovation systems. We designed a comprehensive set of technology-specific indicators for innovation system processes. The exhaustive list technology-specific indicators can be used broadly in innovation system research communities to improve and to modify indicators to assess the processes and performance of energy innovation systems. To demonstrate the usefulness of this exhaustive list of technology-specific indicators, we suggest three applications: (1) tracking changes over time; (2) characterising innovation portfolio; and (3) analysing causal relationships. The proposed set of technology-specific indicators enables a more holistic assessment of energy technology innovation processes and performances.
