Abstract:
Adjustment costs are a central bottleneck of the real-world economic transition essential for achieving the sizeable reduction of greenhouse gas (GHG) emissions set out by policy makers. Could these costs derail the transition process to green growth, and if so, how should policy makers take this into account? I study this issue using the model of directed technical change in Acemoglu, Aghion, Bursztyn, and Hemous (2012), AABH, augmented by a friction on the choice of scientists developing better technologies. My results show that such frictions, even minor, materially affect the outcome. In particular, the risk of reaching an environmental disaster is higher than in the baseline AABH model. Fortunately, policy can address the problem. Specifically, a higher carbon tax ensures a disaster-free transition. In this case, the re-allocation of research activity to the clean sector happens over a longer but more realistic time horizon, namely around 15 instead of 5 years. An important policy implication is that optimal policies do not act over a substantially longer time horizon but must be more aggressive today in order to be effective. In turn, this implies that what may appear as a policy failure in the short-run | a slow transition albeit aggressive policy | actually re ects the efficient policy response to existing frictions in the economy. Furthermore, the risk of getting environmental policy wrong is highly asymmetric and `robust policy' implies erring on the side of stringency.

Abstract:
With 25% of worldwide emissions due to road transport, the deployment of electric vehicles (EVs), full battery electric vehicles and plug-in hybrid electric vehicles – presents many promises to mitigate climate change. Despite its rapid growth, the market share of EVs vehicle remains low in Europe. Norway leads the EV market with 10% of total vehicle stock, followed by Iceland (3.3%), the Netherlands (1.9%) and Sweden (1.6%) (IEA, 2019). This Policy Brief presents the results of a survey among European clean tech investors examining which policy instruments and design can best mobilize private investments to advance e-mobility technologies.

Abstract:
Substantial private investment is required if public policy objectives aim to increase the market share of Electric Vehicles (EVs) and prevent locking-in emissions-intensive development pathways. To maximize the effectiveness of future policies and successfully attract private capital, policy makers need to gain a better understanding of how investors behave, and of how policy design can drive investments decisions. This paper leverages an adaptive conjoint analysis (ACA) method to investigate the policy preferences of 41 European investors affiliated with different investment institutions. Findings reveal that investors' characteristics as institution type and size of assets under management affect investors' preferences over different e-mobility policy attributes. Furthermore, this study shows that behavioral factors, namely investors' a-priori beliefs on the impacts of climate change and the COVID-19 crisis, play a role in determining investors' policy preferences. By providing an analysis of investors' behavior, this research can support policymakers to design more effective policy instruments to attract investments in electric mobility during and after the COVID-19 crisis.

4. The heterogeneous impact of coal prices on the location of cleaner and dirtier steel plants

Abstract:
Climate policy will predominantly affect industries that primarily rely on fossil fuels, such as steelmaking. Within these industries, exposure may be different by country according to the energy-intensity of national plants. We estimate the effect of coal prices on steel plant location worldwide and production preferences for BOF, a polluting technology, and EAF, a greener one. A 1% increase in national coal prices reduces BOF installed capacity by around 0.37%, while it has no statistically significant impact on EAF capacity. We simulate the implementation of a stringent European carbon market with no border adjustment and find a non-negligible shift in steel production outside Europe, with a concomitant impact on the technologies employed to produce steel. If applied worldwide, the same policy would primarily affect production in Asia, which relies on BOF and currently benefits from lower coal prices than those expected to emerge in the future.

Policy Brief

Abstract:
Mobilizing private investments for the renewable energy transition requires credible policy support over the long-term. This Policy Brief discusses how Romania’s abrupt policy changes and inconsistent policy signals over the last decade have deterred private investments in the renewable energy sector. The example of Romania provides key policy lessons for other countries engaged in the energy transition. Romania has one of the highest renewable energy potentials in Europe (up to 71 GW), which is approximately six times higher than the country’s current renewable deployment (IRENA 2017). As shown in Figure 1, wind and solar PV energy experienced a significant boom between 2009 and 2013 followed by a more or less complete stagnation since 2014.

Abstract:
The objective of this study is to examine the impact of firms' financing constraints on innovation activities in renewable (REN) versus fossil-fuel (FF) technologies. Our empirical methodology relies on the construction of a firm-level dataset for 1,300 European firms over the 1995-2009 period combining balance-sheet information linked with patenting activities in REN and FF technologies. We estimate the importance of the different types of financing (e.g. cash flow, long-term debt, and stock issues) on firms' patenting activities for the different samples of firms. We use count estimation techniques commonly used for models with patent data and control for a large set of firm-specific controls and market developments in REN and FF technologies. We find evidence for a positive impact of internal finance on patenting activities for the sample of firms specialized in REN innovation, while we find no evidence of this link for other firms, such as firms conducting FF innovation or large mixed firms conducting both REN and FF innovation. Hence, financing constraints matter for firms specialized in REN innovation but not for other firms. Our results have important implications for policymaking as the results emphasize that small innovative newcomers in the field of renewable energy are particularly vulnerable to financing constraints.

Abstract:
This paper analyses the impact of green innovation on energy intensity in a set of 14 industrial sectors in 17 OECD countries over the 1975-2005 period. We create a stock of green patents for each industrial sector and estimates a translog cost function to measure the impact of green innovation on energy intensity, next to other factors such as input substitution and autonomous technical change. We find that green innovation has contributed to the decline in energy intensity in the majority of sectors: the median elasticity of energy intensity with respect to green patenting is estimated at -0.03 in our sample. Hence, a 1% increase in green patenting activities in a given sector is associated with a 0.03% decline in energy intensity. The magnitude of the effect is larger in energy-intensive sectors and in more recent years. We also find that the impact of an additional green patent on energy intensity is larger than an average non-green patent. Our results are robust to alternative definitions of patents.

Abstract:
This paper presents novel empirical evidence on the internationalization of green R&D by multinational firms (MNCs), as measured by patents data. Using data on inventors’ addresses for the set of 1,200 MNCs firms patenting in green technologies over the 2004-2009 period, we find that about 17% of green patents result from MNCs R&D investments conducted outside their home countries. MNCs tend to locate their foreign green R&D activities in other OECD markets and in China, in particular in lightings and solar technologies. The empirical analysis reveals that the probability of conducting green R&D abroad increases with the host country’s stringency of environmental regulation, market size and (green) R&D intensity. Also, relatively lower wages for scientists and engineers, and stronger protection for intellectual property rights in the host country increase the likelihood for MNCs to offshore green R&D. The paper concludes by discussing the policy implications of this changing global innovation landscape.
