Urban infrastructure investment and rent-capture potentials (anglais)

In a context of rapid urbanization and energy transition, massive investments will be required to develop efficient public transport networks. Capturing the increase in land value caused by transport infrastructure (for example, through a betterment tax) appears a promising way to finance public transport. ... Voir la suite

Agreeing on robust decisions : new processes for decision making under deep uncertainty (anglais)

Investment decision making is already difficult for any diverse group of actors with different priorities and views. But the presence of deep uncertainties linked to climate change and other future conditions further challenges decision making by questioning the robustness of all purportedly optimal solutions. ... Voir la suite

Carbon price efficiency : lock-in and path dependence in urban forms and transport infrastructure (anglais)

This paper investigates the effect of carbon or gasoline taxes on commuting-related CO2 emissions in an urban context. To assess the impact of public transport on the efficiency of the tax, the paper investigates two exogenous scenarios using a dynamic urban model (NEDUM-2D) calibrated for the urban area of Paris: (i) a scenario with the current dense public transport infrastructure, and (ii) a scenario without. ... Voir la suite

Long-term mitigation strategies and marginal abatement cost curves : a case study on Brazil (anglais)

Decision makers facing abatement targets need to decide which abatement measures to implement, and in which order. This paper investigates the ability of marginal abatement cost (MAC) curves to inform this decision, reanalysing a MAC curve developed by the World Bank on Brazil. ... Voir la suite

Green industrial policies : when and how (anglais)

Green industrial policies can be defined as industrial policies with an environmental goal -- or more precisely, as sector-targeted policies that affect the economic production structure with the aim of generating environmental benefits. ... Voir la suite

How capital-based instruments facilitate the transition toward a low-carbon economy : a tradeoff between optimality and acceptability (anglais)

This paper compares the temporal profile of efforts to curb greenhouse gas emissions induced by two mitigation strategies: a regulation of all emissions with a carbon price and a regulation of emissions embedded in new capital only, using capital-based instruments such as investment regulation, differentiation of capital costs, or a carbon tax with temporary subsidies on brown capital. ... Voir la suite

Should marginal abatement costs differ across sectors ? the effect of low-carbon capital accumulation (anglais)

The optimal timing, sectoral distribution, and cost of greenhouse gas emission reductions is different when abatement is obtained though abatement expenditures chosen along an abatement cost curve, or through investment in low-carbon capital. ... Voir la suite

An exploration of the link between development, economic growth, and natural risk (anglais)

Investment decision making under deep uncertainty -- application to climate change (anglais)

While agreeing on the choice of an optimal investment decision is already difficult for any diverse group of actors, priorities, and world views, the presence of deep uncertainties further challenges the decision-making framework by questioning the robustness of all purportedly optimal solutions. ... Voir la suite

How inertia and limited potentials affect the timing of sectoral abatements in optimal climate policy (anglais)

This paper investigates the optimal timing of greenhouse gas abatement efforts in a multi-sectoral model with economic inertia, each sector having a limited abatement potential. ... Voir la suite

A cost effective solution to reduce disaster losses in developing countries : hydro-meteorological services, early warning, and evacuation (anglais)

In Europe, it can be estimated that hydro-meteorological information and early warning systems save several hundreds of lives per year, avoid between 460 million and 2.7 billion Euros of disaster asset losses per year, and produce between 3.4 and 34 billion of additional benefits per year through the optimization of economic production in weather-sensitive sectors (agriculture, energy, etc.). ... Voir la suite

Modeling the roles of heterogeneity, substitution, and inventories in the assessment of natural disaster economic costs (anglais)

Based on an IO structure, the ARIO-inventory model simulates the economic consequences and responses to a natural disaster. It represents explicitly production bottlenecks, models a flexibility in production capacity in case of scarcity, and introduces inventories as an additional flexibility in the production system. ... Voir la suite

From growth to green growth -- a framework (anglais)

Green growth is about making growth processes resource-efficient, cleaner and more resilient without necessarily slowing them. This paper aims at clarifying these concepts in an analytical framework and at proposing foundations for green growth. ... Voir la suite

When starting with the most expensive option makes sense : use and misuse of marginal abatement cost curves (anglais)

This article investigates the use of expert-based Marginal Abatement Cost Curves (MACC) to design abatement strategies. It shows that introducing inertia, in the form of the "cost in time" of available options, changes significantly the message from MACCs. ... Voir la suite

How economic growth and rational decisions can make disaster losses grow faster than wealth (anglais)

Assuming that capital productivity is higher in areas at risk from natural hazards (such as coastal zones or flood plains), this paper shows that rapid development in these areas -- and the resulting increase in disaster losses -- may be the consequence of a rational and well-informed trade-off between lower disaster losses and higher productivity. ... Voir la suite

Designing climate change adaptation policies : an economic framework (anglais)

Adaptation has long been neglected in the debate and policies surrounding climate change. However, increasing awareness of climate change has led many stakeholders to look for the best way to limit its consequences and has resulted in a large number of initiatives related to adaptation, particularly at the local level. ... Voir la suite
