Interlinkages between the just ecological transition and the digital transformation
Full text linkNotwithstanding increasing policy and academic debate around the 'twin' digital and ecological transitions, there is no systematic assessment of their linkages, potential synergies and trade-offs. Most fundamentally, the full extent of challenges that their interaction poses for the prospects of a 'just transition' is not fully understood. This paper discusses the role and impact of digital technologies on two key objectives of a just sustainability transition, namely (1) the creation of decent-quality employment in (2) the pursuit of climate change mitigation and, more broadly, sustainability. In addition, it also discusses (3) whether and how digitalisation affects society more broadly, with a particular focus on how digital technologies can contribute to or reduce existing inequalities, as well as promote social dialogue at all levels. For each of these three aspects, evidence is presented regarding either the negative or positive effects of a number of digital technologies in several key sectors. Based on this evidence, the rationale for jointly addressing these transformations is explained and key policy implications are put forward

Il capitolo quarto presenta un database di brevetti in technologie energetiche efficienti. Il capitolo quinto studia le determinanti dell’efficienza energetica nella produzione di energia elettrica da fonti fossili, con particolare attenzione al ruolo della tecnologia.This dissertation is a collection of essays on innovation, diffusion and adoption of energy technologies. Chapter 1 presents a state-of-the art review of empirical contributions on TC dynamics as applied to eco-innovation. Chapter 2 explores the main determinants of knowledge flows and how they favor or hinder the flow of knowledge across border. Both geographical and technological distance hinder the flow of eco-knowledge. Chapter 3 identifies the main demand and supply-side determinants of innovation, with particular attention to the role of foreign knowledge. I point to the importance of knowledge spillovers in fostering further eco-innovation, especially in countries with medium to low innovative abilities. Chapters 4 and 5 focus on TC in the electricity sector, a main contributor to GHG emissions. In Chapter 4 presents the data selection process used to identify patents in efficient fossil electricity technologies and provides a worldwide analysis of innovation trends in these technologies. Chapter 5 studies the evolution of energy efficiency in fossil-fuel based electricity production, devoting particular attention to the contribution of knowledge to production efficiency
Environmental Policy and the International Diffusion of Cleaner Energy Technologies
No full textTechnology transfer is an important channel of technological change and sustainable development for countries with less innovative ability than technological leaders. This paper studies whether domestic environmental policies affect the inward technology transfer of cleaner innovation from abroad.We focus specifically on the power sector, for its important role in the decarbonization process, by looking at zero-carbon (renewable) and carbon-saving (efficient fossil) technologies for energy production. Using data on cross-country patent applications, we provide evidence that environmental policy contributes to attracting foreign cleaner technology options to OECD markets but not to non-OECD markets. We show that this is due to the nature of the implemented policy instruments. Market-based approaches positively impact technology transfer to both OECD and non-OECD economies, while non-market based approaches have at best only a weak effect in OECD countries. Domestic
environmental policies may provide too weak a signal for foreign innovators in countries off the technological frontier. This calls for a strengthening of policy incentives for technology transfer in light of pressing climate change objectives
Bending the learning curve
Full text linkThis paper aims at improving the application of the learning curve, a popular tool used for forecasting future costs of renewable technologies in integrated assessment models (IAMs). First, we formally discuss under what assumptions the traditional (OLS) estimates of the learning curve can deliver meaningful predictions in IAMs. We argue that the most problematic of them is the absence of any effect of technology cost on its demand (reverse causality). Next, we show that this assumption can be relaxed by modifying the traditional econometric method used to estimate the learning curve. The new estimation approach presented in this paper is robust to the reverse causality problem but preserves the reduced form character of the learning curve. Finally, we provide new estimates of learning curves for wind turbines and PV technologies which are tailored for use in IAMs. Our results suggest that the learning rate should be revised downward for wind power, but possibly upward for solar PV
Measuring environmental policy stringency: Approaches, validity, and impact on environmental innovation and energy efficiency
Full text linkSolid tests of the impact of environmental and energy policy on important economic outcomes, such as innovation, productivity, competitiveness and energy and carbon efficiency are impaired by the lack of appropriate empirical proxies for the commitment to, and stringency of, environmental policy. We contribute to the literature by: (1) computing different indicators of environmental policy stringency, (2) testing to what extent they convey similar insights through a statistical comparison exercise, and (3) showing the implications of using one or the other indicator in two illustrative empirical applications focused on environmental innovation and energy efficiency. We conclude by highlighting the implications of our analysis for empirical research focusing on the evaluation of policy impacts, and highlight fruitful future research avenues
Induced technological change and energy efficiency improvements
No full textWe present a theoretical and empirical model which (1) shows that the demand for energy is shifted down by innovations in energy intensive sectors and (2) highlights the drivers of innovative activity in these sectors. The theoretical model and the empirical analysis of patent and energy data indicate that the level of innovative activity is determined by energy expenditure as well as international and inter-temporal spillovers. The solution of the theoretical model along the balanced growth path suggests that in general equilibrium the level of innovative activity depends on the growth rate of energy generation cost. The model predicts also that a level increase in the cost of energy does not alter the long-run energy share of income. Finally, we show that our results can be used to calibrate Integrated Assessment Models to project energy efficiency growth
Robust multivariate analysis for mixed-type data: Novel algorithm and its practical application in socio-economic research
Full text linkWe propose a novel method and algorithm for the analysis and clustering of mixed-type data using a hierarchical approach based on Forward Search. In our procedure, the identification of groups is based on the identification of similar trajectories and then linked to very intuitive two-dimensional maps. The proposed algorithm can use different measures for the calculation of distance in the case of mixed-type data, such as Gower’s metric and Related metric scaling. A key feature of our algorithm is its ability to discard redundant information from a given set of variables. The practical usefulness of the algorithm is illustrated through two applications of high relevance for empirical economic research. The first one focuses on comparing different indicators of environmental policy stringency in different countries. The second one applies our procedure to identify clusters of countries based on information regarding their institutional characteristics
Systematic review of the outcomes and trade-offs of ten types of decarbonization policy instruments
Full text linkThe literature evaluating the technical and socioeconomic outcomes of policy instruments used to support the transition to low-carbon economies is neither easily accessible nor comparable and often provides conflicting results. We develop and implement a framework to systematically review and synthesize the impact of ten types of decarbonization policy instruments on seven technical and socioeconomic outcomes. Our systematic review shows that the selected types of regulatory and economic and financial instruments are generally associated with positive impacts on environmental, technological and innovation outcomes. Several instruments are often associated with short-term negative impacts on competitiveness and distributional outcomes. We discuss how these trade-offs can be reduced or transformed into co-benefits by designing research and development and government procurement, deployment policies, carbon pricing and trading. We show how specific design features can promote competitiveness and reduce negative distributional impacts, particularly for small firms. An online interactive Decarbonisation Policy Evaluation Tool allows further analysis of the evidence
