Abstract:
Protected areas and indigenous communities play a crucial role in controlling deforestation, which is responsible for carbon emissions related to land use and land use change, contributing to global warming and climate change. However, the effectiveness of protected areas is conditioned by their administration and the quality of the institutions in their countries. In this paper, I will analyze the effectiveness of protected areas (Both at the national and sub-national levels) and indigenous territories and the institutions' role in the case of Bolivia's lowlands. I computed deforestation rates for four different periods between 1986 and 2021 to test the impact of institutions on different types of protected areas by using satellite images at 30m resolution and combining them with official data on protected areas and indigenous communities, which includes specific locations and dates of creation. Using a spatial regression discontinuity design, the results show that protected areas at the national level are the most effective in controlling deforestation, particularly after the creation of institutions taking care of them. Departmental protected areas have some impact on preventing deforestation, while municipal ones have no influence. For indigenous communities, there was a significant effect on reducing deforestation with the first reservations created, but the effect wears off over time. Regarding mechanism, being close to cities and routes is a threat for indigenous communities and departmental PAs, while it is an advantage for national PAs. Finally, protected areas and indigenous communities show, in general, greater levels of deforestation when they are exposed to cattle ranching settlements, mines, and oil wells.

2. Redressing environmental harm? A 'corporate sovereignty' problem

Abstract:
The transition towards a low-carbon economy is an epoch-defining goal. However, this transition develops following traditional patterns of business that are intrinsically environmentally harmful as they rest upon profit-oriented strategies of commodifying natural resources. By taking the anthropological notion of "corporate sovereignty", this contribution discusses the unsustainability of private corporates' property a-like structures of power over natural resources and frames them within forms of economic governmentality. The paper concludes by stressing the need for a cultural change to occur to back the transition towards a novel model of sustainable business, i.e. of "business within the Heart's limits".

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.

4. Cumulative climate shocks and migratory flows: evidence from Sub-Saharan Africa

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.

5. Can adjustment costs in research derail the transition to green growth ?

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. Details

Abstract:
Achieving the goals of the Paris Agreement and of climate neutrality by 2050 in the European Union will require mobilizing financial investments towards clean energy innovation. This study examines the role of internal finance (cash flows and cash holdings) and financing constraints for innovation in energy technologies. We construct a dataset for 1,300 Europeans combining balance-sheet information and patenting activities in renewable (REN) and fossil-fuel (FF) technologies and estimate the sensitivity of patenting activities to's internal finance. We use count estimation techniques and control for a large set of-specific characteristics and market developments in REN and FF technologies. We find that patenting activities ofs specialized in REN innovation are significantly more sensitive to a shock in cash flows thans specializing in FF innovation. Hence, our results emphasize that innovatives in clean energy may be particularly vulnerable to financing constraints. We discuss the implications of these results for energy transition policies aiming to redirect finance towards clean energy R&D.

Abstract:
We build a novel news-based index of US environmental policy and examine how it relates to clean investments. Extracting text from ten leading US newspapers over the last four decades, we use text-mining techniques to develop a granular index measuring the salience of US environmental policy (EnvP) over the 1981-2019 period. We develop further a set of additional measures, namely an index of sentiment on environmental policy, as well as various topic-specific indices. We validate our index by showing that it correctly captures trends and peaks in the evolution of US environmental policy and that it has a meaningful association with clean investments, in line with environmental regulations supporting growing opportunities for clean markets. In firm-level estimations, we find that the salience of environmental policy in newspapers is associated with a greater probability of cleantech startups receiving venture capital (VC) funding and reduced stock returns for high-emissions firms most exposed to environmental regulations. At the aggregate level, we find in VAR models that a shock in our news-based index of renewable energy policy is associated with an increase in the number of clean energy VC deals and in the assets under management of the main benchmark clean energy exchange-traded fund. Overall, our EnvP index provides a lot of substantial information on environmental policy and can help assist the policy and financial community in understanding how these regulations are perceived by investors | providing many avenues for future research.
