  • 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: 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.

  • 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.
