Title

Do subjective perceptions and accuracy shape adaptation to climate change? Evidence from Bangladesh

 
Extract
This paper examines how subjective perceptions of climate change of rural households in Bangladesh influence their irrigation adaptive decisions. Using a unique national-representative panel dataset of farmers in Bangladesh, I study the effect of subjective perceptions on the use of different types of irrigation in diverse growing seasons. I formalize a theoretical framework in which subjective perceptions depend on the reference environment agents are exposed to, and test the implications. I also define and empirically validate the hypothesis that farmers are subject to availability bias, finding that self-reported recent drought events lead to overreaction in the use of irrigation on the cultivable land, with the effect vanishing after one period. By comparing farmers’ recollection of self-reported drought events and objectively recorded events, I find that the accuracy of farmers explains differences in the irrigation adaptive decisions, with different reactions to under and overestimation of these events. A detailed comprehension of farmers’ perceptions of climate change and adaptation strategies can significantly contribute to the design of adequate policies for agricultural security.

Title

Roads Investment, Development and Deforestation

 
Extract
We build a quantitative spatial model to study the impact of investments in transportation infrastructure on forest losses in the Brazilian Amazon. We examine how new roads (or the modernization of existing ones) change the spatial equilibrium of agriculture, modify trade opportunities and cause deforestation. We quantify the model using a novel data-set combining agricultural census data and satellite-data on both forest cover and road networks. We find that a decrease in transport costs by 10% between the states of the so-called “arc of deforestation” and the closest international port increases deforestation by approximately 4% in this region. We highlight the general equilibrium effects related to this result and examine several important outcomes related to structural transformation.

Title

Carbon taxes in a global production network

 
 
Abstract
 
The goal of this paper is to understand better carbon taxation in the context of an increasingly integrated global production network. We present a model that characterizes how, departing from sector idiosyncratic policy shocks, the structure of the global production network is able to generate sizeable fluctuations on aggregate output and emissions. We depart from a stream of literature that uses network structures in the framework of general equilibrium models in order to characterize the microeconomic origins of aggregate fluctuations. We extend previous models in order to, among other features, include carbon taxation and accommodate the structure of an environmental multi-regional input-output database. We provide an empirical representation of the different network effects that play a role in spreading globally the effects of carbon taxation. We are able to identify a very small set of sectors that possesses most of the emissions reduction potential. Second-order policy effects define synergies between policies that call for greater harmonization in the application of carbon taxation around the world.

Title

Evaluating the management of radioactive waste – Methodological issues

 
 
Abstract
 
The nuclear activities of many countries have generated, for more than half a century, a considerable stockpile of radioactive waste, some with high activity and / or long-lived, which must be managed in a safer and more sustainable manner than this is not the case today. In addition, the civilian use of nuclear energy is set to continue for at least several decades and even represents, for some, an important element of strategies to combat global warming. The problem of nuclear waste management is therefore bound to endure on the one hand and, on the other hand, to interfere with debates on climate policy. In France, the legislator opted in 2006 for a geological disposal solution for high-level, long-lived radioactive waste, and entrusted this responsibility to the Agency for the management of radioactive waste (Andra). Andra has developed in stages a storage project called Cigeo and located near the town of Bure, on the border of the Meuse and Haute-Marne. This project should soon be the subject of a public utility declaration file, which includes a socio-economic assessment (SEA).
To advise it in the conduct of this evaluation, Andra set up a Committee of economist experts which has met regularly over the past two years, contributed to the development of a method and supervised the work of ‘ESE. In particular, the Committee had to respond to the considerable methodological challenges posed by the assessment of nuclear waste management solutions, particularly in taking into account the very long term and the representation of radical uncertainty for the public decision-maker. These methodological questions, familiar as they are to the climate economist, arise here with even greater acuteness than in the debates on the fight against global warming. Indeed, the various waste management choices involve costs, benefits and risks that extend not over decades or centuries, but tens of millennia, and bring into play extreme scenarios for the evolution of the environment. society.
 
The seminar will seek to present the main lines of the project, give an overview of the methodological challenges posed by its evaluation and analyze the practical responses proposed by the committee of experts, in particular by mobilizing recent advances in economic theory in an open manner. and accessible.

Title

Fossil resource markets and climate change

 
 
 
Abstract
 
This talk will present recent research results from the ongoing economic research project Fossil resource markets and climate change. Achieving the Paris agreement requires a radical transformation of the energy system and, most notably, a strong reduction of the use of fossil fuels. Hence, assets in the form of fossil energy resources and infrastructure are at the risk of losing value and becoming „stranded assets”. Asset owners have incentives to delay or even prevent the implementation of climate policies. We investigate how long-lived investments and the risk of asset stranding hinder the effectiveness of climate policy. This talk highlights research results on potential global fossil energy scenarios to 2050 as well as regional asset stranding risks in coal and natural gas markets.

Title

Is climate a curse or a bless in the Covid-19 virus fighting?

 
 
 
 
Abstract
 
Faced with the global pandemic of Covid-19, we need to better understand the links between meteorological factors and the virus and investigate the existence of potential seasonal patterns. In the vein of a recent empirical literature, we reassess the impact of weather factors on Covid-19 daily cases in a panel of advanced and emerging countries between January the first and 28th May 2020. We consider 5 different meteorological factors and go further previous studies. In addition, we give a short-run and medium/long-run time perspective of the dramatic outcomes of the pandemic by both considering infected people (short-run) and fatalities (long-run). Our results reveal that the choice of delays and time perspective of the effects of climatic factors on the virus are crucial as well as Covid-19 outcomes can explain the discrepancies in the previous literature. For the first time, we use a dynamic panel model and consider two different kinds of channels between climate and Covid-19 virus: 1) direct/physical factors related to the survivals and durability dynamics of the virus in surfaces and outdoors and 2) an indirect factor through human behaviors and individual mobility – walking or driving outdoors – to capture the impact of climate on social distancing and thus on Covid-19 outcomes. Our model is estimated \emph{per se} two different estimators and persistence, delays in patterns, nonlinearities and numerous specifications changes are taken into account with many robustness checks. Our work reveal that temperatures and, more interestingly, solar radiation – that has been clearly undervalued in previous studies – are significant climatic drivers on Covid-19 outbreak. Indirect effects through human behaviors ie interrelationships between climatic variables and people mobility are significantly positive and should be considered to correctly assess the effects of climatic factors. Since climate is per se purely exogenous, climate tend to strengthen the effect of mobility on virus spread. The net effect from climate on Covid-19 outbreak will thus result from the direct negative effect of climatic variables and from the indirect effect due to the interaction between mobility and them. Direct negative effects from climatic factors on Covid-19 outcomes – when they are significant – are partly compensated by positive indirect effects through human mobility. Suitable control policies should be implemented to control the mobility and social distancing.

Covid-19 and global warming

Résumé
It is unimaginable that the shock of Covid-19, having affected billions of people simultaneously, will be only a parenthesis before the “return to normal”. In this book, Christian de Perthuis attempts to discern the transformations in the economic organization and the social sphere that are likely to modify the conditions of climate action in the future. “The coronavirus has brought the powerful to their knees and the world to a halt like nothing else could. Our thoughts still rush back and forth, dreaming of a return to normal, trying to connect the future to the past, to stitch them together, refusing to admit the breakup. Arundhati Roy The economy of containment has brought the world to a halt. The Covid-19 has purified the air in our cities and brought down CO2 emissions like no policy before. In an emergency, he imposed drastic reorganizations of production, trade and work. It deepened inequalities, but catalyzed new forms of solidarity. A shock that has affected billions of people simultaneously cannot constitute a simple parenthesis before the “return to normal”. In this essay, Christian de Perthuis urges us not to try to “stitch the future and the past together”, to use Arundhati Roy’s beautiful phrase. He suggests operating “back and forth” between one and the other to shed light on the ruptures that will structure the world of tomorrow. It reveals to us what the health disaster can change for climate action. The post-Covid-19 world will be more digital and less carbon intensive. The redistribution of the flow of people and goods paves the way for an acceleration of the energy transition. Distributive carbon pricing, that of more united societies. The fight against the emergence of new viruses obliges us to respect nature better: to protect the ecosystems that store CO2 from the atmosphere and ward off attacks from new viruses. The post-Covid-19 economy will have to be based on new relationships with the natural environment and the multitude of living beings that make it up.

Title

Extended Producer Responsibility, Packaging Waste Reduction and Eco-design

 

Abstract
 
The main policy addressing the packaging waste issue in the countries of the European Union has been to define recycling objectives along with Extended Producer Responsibility (EPR). With EPR, producers finance the recycling and management of waste generated by their products. Within this framework they are expected to internalise waste management costs and engage in eco-design of their packaging, i.e., use less packaging and increase packaging recyclability (e.g., through substitution of materials). EPR has been extended worldwide over recent decades and applied to various waste streams. In this paper, by exploiting temporal variation of an original panel dataset of EPR compliance costs from 25 European countries (1998-2015) and four packaging materials, I evaluate for the first time whether these costs have led to packaging waste reduction and substitution of packaging materials. I find that the EPR financial incentive has resulted in very little (though statistically significant) packaging reduction and no systematic substitution effects between packaging materials.

Annual report Carbon neutrality 2020: “Straightening the course, relaunching the transition”

 

Abstract
 
The second annual Carbon Neutrality report of the High Council for the Climate was prepared under specific conditions. Influenced by the health crisis and its economic and social impacts, it is published in the context of a change of government, which intends to accelerate on environmental priorities. Clear expectations are formulated in society, by all generations and across the country, in terms of solidarity in the face of risks and actions favorable to the environment.

The new government inherits the responsibility of managing and emerging from successive health, economic and social crises towards a society and economy that are less vulnerable, better adapted and more resilient to external shocks. Global warming induced by human activities continues to worsen, while France’s climate actions are not up to the challenges or the objectives it has set for itself. The government must resume the course towards carbon neutrality. The recovery planned by the government after the crisis must first be that of the transition that allows compliance with the carbon budgets defined by law. There are few deficits that states cannot afford to ignore: the carbon deficit is one of them. It does not repay itself across our generations, and its interest is paid on our living conditions.

Our annual report shows that this framework is compatible with legitimate employment or health concerns. This transition is possible, useful and inevitable. It involves firm and transversal inter-ministerial management with the national low-carbon strategy as a reference. It calls for improving the accountability of the State, in particular through the objective evaluation and strengthening of its public policies. Under these conditions, the French population will appropriate climate policies, their constraints and their benefits. In addition, the need to be associated with decisions and their implementation is at the heart of the positive response to the Citizen’s Climate Convention. This is also the reason why the High Council for the Climate wanted this year to pay particular attention to the challenges of the just transition and to help advance the debate on the subject, in these times of democratic choices.

The medium and long-term impact of the decisions that will be taken in the coming months should not be underestimated. It places a particular responsibility on the public and private leaders who will have to decide. The High Council for the Climate makes its work available to help them.

What is the impact of energy renovation of housing on energy consumption? Ex post evaluation on panel data

 

Abstract
 
This article provides an ex post evaluation of the impact of energy renovation works in the residential sector on energy expenditure using data from the Energy Management survey carried out by TNS-SOFRES for the ADEME in 2000 to 2013. The model with fixed effects and instrumental variables identifies a very modest effect of the work since an additional € 1,000 spent leads to an average reduction in the annual energy bill of € 8.29 (or – 0.64%). Consequently, the discounted net profit from the renovation of an average dwelling is very negative. These results question the relevance of subsidies and public aid for renovation if they are motivated solely by energy savings.
