This program introduces participants to cutting-edge research on the topic and familiarizes them with the relevant methods to analyze (econometric analysis, dynamic modelling). The objective of the course is to equip the participants with the background and tools that are needed to contribute to this dynamic field in terms of research and policy design and evaluation.

The main questions we cover are the following. How is the social cost of carbon calculated for regulatory purposes ? How can uncertainty and inequalities be integrated in climate policy ? What role does trade play in adaptation to climate change ? What are the drivers of deforestation and how can policies reconcile effective carbon sequestration and distributive effects ? What are the effects of climate change on migration ? By what means can individuals and groups insure against the risks of climate change and natural disasters, and how do public adaptation investments interact with private incentives ?

Risk, Inequality, and Climate Policy - Marc Fleurbaey and Stéphane Zuber

Overview
Climate change triggers a “perfect moral storm,” (Gardiner) in the sense that it is very hard to evaluate climate policy due to its long-term horizon, the multiple impacts of climate change on populations, the deep uncertainty, and the inequalities across and within generations that will be affected. It is important to have a good tool to assess climate policy in all its aspects.

We will first present issues related to the intertemporal aspects of the climate policies, including the question of discounting. We will then discuss how alternative approaches (Epstein-Zin preferences, robust preferences, etc.) can deal with the management of catastrophic risk. We will present issues of inter- and intra-generational equity and how we can wrap up inequalities, risk, time, and population. Applications using numerical models will be discussed.

Measuring the Effects of Climate Change, Carbon Pricing, and Natural Disasters in the Presence of Spillovers - Hélène Ollivier

Overview
This course will cover the latest research on how to estimate the effects of climate change (namely, temperature and rainfall shocks), the effects of carbon pricing, and the effects of natural disasters when there are spillovers across countries, sectors or firms. We will focus on ex post analysis and study model-based estimation strategies that account for these spillovers. We will consider models built on international trade and industrial organization workhorse models and derive new implications for our understanding of the effects of climate change, carbon pricing, and natural disasters.

Climate Change and Long-term Forest Policies - François Libois

Overview
Forest ecosystems play a critical role in long-term carbon sequestration but they are also very important in the short-run for human livelihoods. Deforestation and forest degradation, while eventually producing short-term benefits for some economic agents, have short-term and long-term distributional consequences in terms of welfare, by accelerating climate change and by hampering the livelihoods of forest dependent people. This module will discuss drivers of forest change, whether institutional, economic or related to public policies, as well as some of their consequences. Given the nature and diversity of forests, the course will emphasize changes that most probably have medium to long-term effects and separate as much as possible discussions about the quantity of forests and their quality.

The Effects of Climate Change on Migration - Katrin Millock

Overview
This module aims at understanding mobility responses to climate change and migration as a means of adaptation to climate change.

The module will focus on the main empirical methods that are used to identify the effects of climate change on migration. The spectrum of models covered will include the random utility model and its empirical counterpart (the gravity model), and general equilibrium models. We will also discuss predictions of future migration flows linked to climate change and to what extent such predictions are reliable. Participants will learn about recent approaches to better model the mechanisms underlying this specific form of adaptation, and the relation of migration to other adaptation strategies. The module thus intends to give participants an understanding of the methods currently used to predict future climate-related migration, and the remaining challenges in identifying mobility responses to climate change.

Risk, Insurance, and Adaptation to Natural Disasters - Matthew Gordon

Overview
This module will study how individuals and groups can insure against the risks of climate change and natural disasters through informal networks, migration, and technological adaptation. We will also study adaptation frictions – why moral hazard and adverse selection inhibit the ability to manage climate and disaster risks. In particular we will look at how public adaptation investments interact with private incentives. The module will cover recent studies of these topics using a variety of methodologies including structural models and reduced form causal inference.
