Innovation in Concentrating Solar Power Technologies: A Study Drawing on Patent Data

Better understanding the innovative process of renewable energy technologies is important for tackling climate change. Though concentrating solar power is receiving growing interest, innovation studies so far have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and solar thermal technologies. This study relies on patent data to examine international innovative activity in concentrating solar power technologies. Our unique contribution, based on engineering expertise and detailed datawork, is a classification system matching solar thermal technologies to the International Patent Classification (IPC) system. To this end we suggest a narrowly defined set of IPC classes and a broader one of technologies relevant to CSP, but not exclusively so. We moreover exploit information from three international patent offices, the European, the United States and the Japanese patent office. Innovative activity in narrowly defined CSP technologies has experienced an early boom before 1980 and only recently showed some signs of more activity - a pattern closely resembling the R&D support path. R&D and innovation are concentrated in few high-tech countries - such as the U.S. or Germany. Large CSP potential is not a sufficient condition for innovation, only developed countries such as Australia with both CSP potential and adequate economic and scientific capabilities are found to be among the group of relevant innovators.Innovation, patent data, solar technologies, climate change

Exploring the Nature of Strategic Interactions in the Ratification Process of the Kyoto Protocol

Do countries interact when they decide whether or not to ratify the Kyoto Protocol? If so, what is the nature of these interactions? To answer these questions, we provide a theoretical analysis based on the notions of strategic substitutability and strategic complementarity. Firstly, we analyze the nature of interactions between countries when they are merely seeking to provide a global public good. Secondly, we argue that countries have ties in several spheres in the real world and we try to shed light on the nature of the strategic interactions generated by geographic proximity, trade flows, and green investment flows. The empirical investigation is realized via the estimation of a parametric survival model, and our data sample covers 164 countries for the period from 1998 to 2009. We find evidence that, while countries' ratification decisions are originally strategic substitutes, they became strategic complements when we focus on the ratification decisions of specific peers.Ratification, Kyoto Protocol, International Environmental Agreements, Spatial survival model

Invention and diffusion of water supply and water efficiency technologies: insights from a global patent dataset

This paper identifies over 50 000 patents filed worldwide in various water-related technologies between 1990 and 2010, distinguishing between those related to availability (supply) and conservation (demand) technologies. Patenting activity is analysed – including inventive activity by country and technology, international diffusion of such water-related technologies, and international collaboration in technology development. Three results stand out from our analysis. First, although inventive activity in water-related technologies has been increasing over the last two decades, this growth has been disproportionately concentrated on supply-side technologies. Second, whilst 80% of water-related invention worldwide occurs in countries with low or moderate water scarcity, several countries with absolute or chronic water scarcity are relatively specialized in water efficiency technologies. Finally, although we observe a positive correlation between water scarcity and local filings of water patents, some countries with high water availability, in particular Switzerland or Norway, nevertheless appear as significant markets for water-efficiency technologies. This suggests that drivers other than local demand, like regulation and social and cultural factors, play a role in explaining the global flows of technologies. And finally, the extent to which innovation is "internationalised" shows some distinct patterns relative to those observed for innovation in technologies in general

Climate change policies and income inequality

This paper examines the dynamic impact of Climate Change Policies (CCPs) on income inequality, for a sample of 39 developed and developing countries, during the period 1990–2020. The results show that CCPs are associated with a significant and persistent increase in income inequality. The effect is robust across various measures of inequality and sensitivity tests, including an instrumental variable strategy. The effect of CCPs only materializes in the case of market-based CCPs, is stronger in countries characterized by a higher share of low-educated workers and initial level of inequality, while is mitigated in those with comprehensive redistribution policies, and during periods of fiscal expansions and stronger economic growth. These findings have important policy implications, as they emphasize the importance of the timing and design of CCPs, as well as the role of complementary policies

Game of Tones: A Twail-Analysis of the Evolution and Impacts of the United Nations Framework Convention on Climate Change Technology Transfer Regime in Africa

The 1992 Rio Outcome articulates what is arguably, to date, the most ambitious North–South environmentally sound technology (EST) transfer aspirations. Yet, 26 years post-Rio, Africa remains at the lowest rung of the global EST deployment totem. Departing from talking-points like the connection of EST transfer and intellectual property rights, this research focuses on the normative underpinnings of the history, processes and dynamics of UNFCCC’s EST transfer regime. Using a ‘reconsidered’ Third World Approach to International Law approach and its accompanying historical research methodology, the thesis seeks to track landmarks in UNFCCC’s EST transfer regime evolution and the impacts of a globally commodified climate change structure on EST transfer in Africa. It further considers how previous trends are being reproduced and reiterated in the current regime under the Paris Agreement. It concludes by framing a five-point research agenda for the reformation of the UNFCCC-led global EST development and transfer regime

Climate Policies, Labor Markets, and Macroeconomic Outcomes in Emerging Economies

We study the labor market and macroeconomic effects of introducing a carbon tax in the energy sector in emerging economies (EMEs) by building a framework with equilibrium unemployment and firm entry that incorporates key elements of the distinct employment and firm structure of EMEs. Our model endogenizes the adoption of green energy-production technologies--a core element of policy discussions regarding the transition to a low-carbon economy. Calibrating the model to EME data, we show that a carbon tax fosters greater green technology adoption and increases the share of green energy produced. However, the tax leads to higher energy prices, which reduce salaried firm creation and formal employment and increase self-employment, labor participation, and unemployment. As a result, the tax generates output and welfare losses. Green technology adoption plays a key role in limiting the quantitative magnitude of these losses, while the response of self-employment is crucial to explaining the adverse labor market and macroeconomic effects of the policy. Given this finding, we show that a carbon tax coupled with a plausible reduction in the cost of becoming a formal firm can offset the adverse effects of the tax and generate a transition to a lower-carbon economy with minimal economic costs. Finally, we show that lowering green-technology adoption costs or the cost of green-energy production inputs--two alternative climate policies--reduces emissions while limiting the output and welfare costs compared to a carbon tax

Technology Transfer in the Non-Traded Sector as a Means to Combat Global Warming

The paper considers a situation where two countries - the North and the South - use a non-traded polluting input to produce the goods for final consumption. The North is more efficient in both, production and abatement processes. The study compares the effects of the transfer of abatement technology by the North to the South under autarky with the free trade situation, assuming that the North pre-commits to an international protocol to keep the global pollution under a fixed level. The conditions under which either full or partial technology is transferred in autarky are determined. It is shown that under free trade no such transfer is possible. With trade even though the North wants a complete transfer of technology, the South refuses it
