Abstract:
We use machine learning algorithms to construct a novel news-based index of US environmental and climate policy uncertainty (EnvPU) available on a monthly basis over the 1990-2019 period. We find that the EnvPU index spikes during the environmental spending disputes of the 1995-1996 government shutdown, in the early 2010s due the failure of the national cap-and-trade climate bill and during the Trump presidency. We examine how elevated levels of environmental policy uncertainty relate to investments in the low-carbon economy. In firm-level estimations, we find that a rise in the EnvPU index is associated with a reduced probability for cleantech startups to receive venture capital (VC) funding. In financial markets, a rise in our EnvPU index is associated with higher stock volatility for firms with above-average green revenue shares. At the macro level, shocks in our index lead to declines in the number of cleantech VC deals and higher volatility of the main benchmark clean energy exchange-traded fund. Overall, our results are consistent with the notion that policy uncertainty has adverse effects on investments for the low-carbon economy hindering progress to address the urgency of climate action.

Abstract:
We re-examine the effects of negative weather anomalies during the growing season on the decision to migrate in rural households in five sub-Saharan African countries. To this end we combine a multi-country household panel dataset with high-resolution gridded precipitation data. We find that while the effect of recent adverse weather shocks is on average modest, the cumulative effect of a persistent exposure to droughts over several years leads to a significant increase in the probability to migrate. The results show that more frequent adverse shocks can have more significant and long-lasting consequences in challenging economic environments.

Abstract:
Existing investigations of the impact of school feeding programmes on educational out- comes have provided mixed evidence of success. In this chapter, I investigate a potential explanation for this lack of consensus in the literature. I argue that the prevailing food security situation at the time and place of the programme's evaluation plays a major role. I study the case of rural Malawi. I use an instrumental variable approach and propensity score matching to estimate the impact of school feeding on primary school enrolment and retention rates. I focus on villages with overlapping characteristics. I estimate that school feeding has increased enrolments by 7 percentage points on average, but the im- pact on retention rates has been relatively limited. However, when I distinguish between food-secure and food-insecure areas, not only do I finnd a larger impact on enrolments in food-insecure areas, but I also uncover a significant increase of around 2 percentage points in the retention rate of students in these same areas. Across the board, impacts are not significant in food-secure areas. I conclude that school feeding programmes bear an impact on education as long as they also intervene to relax a binding food constraint.

Abstract:
In this study, we investigate the impacts of the 2002 elimination of primary school fees in Mainland Tanzania. We explore how the magnitude of these effects depends on gender and the size of early investments in the educational infrastructure of Tanganyika. We use the 2002 and 2012 census waves as well as historical information on the location of schools in the late 1940s, and conduct a difference-in-differences analysis. We find that exposure to an average of 1.7 years of free primary education has reduced the proportion of people who have never attended primary education by 6.8 percentage points. The benefits of fee removal have been significantly larger for females compared to males, and females from districts where the size of investments in education was relatively larger during colonial rule have been the greatest beneficiaries.

Abstract:
We study the relationship between housing inequality and crime in South Africa. We create a novel panel dataset combining information on crimes at the police station level with census data. We find that housing inequality explains a significant share of the variation in both property and violent crimes, net of spillover effects, time and district fixed effects. An increase of one standard deviation in housing inequality explains between 9 and 13 percent of crime increases. Additionally, we suggest that a prominent post-apartheid housing program for low-income South Africans helped to reduce inequality and violent crimes. Together, these findings suggest the important role that equality in housing conditions can play in the reduction of crime in an emerging economy context.

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.

Content Type:
Policy Brief
Institution:
Centre for International Environmental Studies, The Graduate Institute (IHEID)
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.

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.
