We analyze the impact of agricultural productivity growth on tropical deforestation. Our dynamic model of forest-to-farmland, addressing the Jevons’ paradox and Borlaug hypothesis, predicts that rising agricultural productivity, reflected by declining fertilizer price growth, has an ambiguous effect on deforestation. Using tropical forest loss data (2000-2022) and fertilizer price variations, we find a negative...
How the increased trade openness and correspondingly higher marginal propensity to import explains the lower efficiency of economic policy in the context of economic openness. Using an empirical stock-flow consistent model for the French economy (SFC FR), we analyze the macroeconomic impacts of these policies through a series of macroeconomic shocks.
The economic agent was previously assumed to be distinct from its environment and that nothing was forcing him to act on it. With the ecological crisis, every agent appears to be inserted into an environment, which he modifies in an irreversible way without even having decided to do so. This changes in depth the...

In September 2020, the city of Bogotá introduced a major market-based reform to its odd-even driving restriction. The big winners of the reform are middle-income individuals who now use their cars more often, whereas the big losers are high-income individuals who now spend more time in traffic.

Adopting disruptive technologies for decarbonizing hard-to-abate industrial sectors requires experimentation through demonstration (pilot) projects. However, from an economic perspective, the potential long-term benefits and the difficulties in designing relevant public policies are not addressed in the standard valuations of those projects.
Our analysis of the Climate Risks and Opportunities Index (CRORI) and the CDP climate score reveal a parallel improvement of these indices with different sectoral disparities over the 2015–2019 period. While our results are encouraging, they need to be put into perspective because these firms are still far from being carbon neutral.
We examine in this paper sustainability-linked bonds (SLBs) whose issuance now totals more than USD 200 bn. There is a structural design flaw in the SLB mechanism: setting a significant coupon step-up does not suit the issuer’s nor the investors’ interests, considering conditionality. This creates a no win situation for the issuer and investors alike and explains the “benign”...
The paper examines the relevant cost benefit framework for state agencies investigating the potential of local projects to mitigate climate change. We propose a new metric that incorporates into the analytical framework the dynamic interactions between the project and its continuation.

We address the long-standing challenge of adding optimal exploration to the classic Hotelling model of a non-renewable resource. We prove that a frontier of critical levels of proven reserves exists, above which exploration ceases, and below which it proceeds at infinite speed.

La crise climatique est source de risques financiers désormais reconnus comme porteurs d’incertitudes multiples, et susceptibles de détériorer l’équilibre du système comme celui de ses acteurs.
Ce séminaire sera l’occasion d’aborder plusieurs questions stratégiques soulevées par les risques climatiques tant pour les banques que pour les autorités de tutelle.
