  • 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: 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: It is no longer possible to achieve the goals of the Paris Climate Agreement – of keeping average global temperatures to ‘well below 2C above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5C1 - without removing large volumes of CO2 from the atmosphere.2 This will involve the development and deployment of carbon negative technologies at the gigatonne scale. Because developmental pathways for such technologies are likely to be decades-long, it is necessary that largescale investment begin now, if we hope to have mature technologies operating at the appropriate scale by 2050.
