This PSE summer school 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 do we measure the impacts of climate change on economic outcomes ? What are the relevant economic instruments to combat climate change in a globalized world ? How can migration and trade help countries and individuals mitigate the impacts of climate change and/or disasters ? How do lobbying and information acquisition influence the actual climate policies ?

Migration and Climate Change – Katrin Millock and Giovanni Peri

(joint with the Migration Program)

This course, which is joint with the Climate Change program, aims at understanding the economic impacts of climate change, with a focus on one particular form of adaptation to climate change : migration.

The course will focus on the measures of climate change and weather variations and the main econometric methods that are used to capture their influence on migration. We will study theoretical models that depart from standard models of migration decisions by including temperature shocks as a parameter. 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 review the literature on empirical estimates : what do the empirical studies predict ? We will discuss the recent approaches to better model the mechanisms underlying this specific form of adaptation, and the relation of migration to other adaptation strategies.

The course thus intends to give participants a thorough understanding of the methods used, their assumptions, and challenges


  • How do we measure climate change impacts using weather data ? A review of empirical methods to estimate the influence of climate change on migration - Katrin Millock, 1.5 hours
  • Analyzing the effects of climate change on migration : theory and empirical identification. Focus on international migration (across countries) and internal rural-urban migration – Giovanni Peri, 3 hours
  • Who are the climate migrants and why do they migrate ? Modelling of forced migration, underlying mechanisms, and in situ adaptation choices – Katrin Millock, 1.5 hours

The Macroeconomics of Climate Change - Katheline Schubert

We will discuss climate change in the perspective of macroeconomic modeling and quantitative evaluation. We present the building blocks of top-down Integrated Assessment Models (IAMs) and discuss the central questions the modeler has to address (discounting, damages, uncertainty, non-linearities, tipping points etc.). We conclude with a presentation of the DICE model and a discussion about the timing of climate policy and the social cost of carbon.

  • Global economy-climate models
  • The DICE model and beyond

Lobbying and private politics - Mireille Chiroleu-Assouline

The objective of this course is to analyse the political economy constraints related to the adoption and implementation of climate change mitigation policies. It will focus on the competition between companies and green NGOs to influence individuals and public decision-makers by providing them with information, whether science-based or biased. The course will explore in depth how the interaction of activist pressure and firms’ lobbying has an impact on international negotiations and environmental regulation.


  • Awareness campaigns and information warfare
  • Political influence in international climate negotiations
  • Lobbying by interest groups and environmental regulation

The effects of trade, the EU ETS, and natural disasters on manufacturing firms - Hélène Ollivier

This course will cover the latest research on trade and the environment, as well as on the effects of the EU ETS and natural disasters on manufacturing firms. We will focus on ex post analysis of trade and policy impacts on firm-level economic and environmental outcomes. We will study how manufacturing firms respond to trade opportunities or competition from abroad, with an emphasis on their decisions that have consequences in terms of CO2 emissions or other pollutants. We will also study the effects of the EU ETS on heterogeneous firms, taking into consideration the facts that the environmental regulation does not cover all manufacturing facilities within the EU countries and that very few countries outside of the EU implemented a similar carbon regulation. Finally, we will study the propagation of the effects of natural disasters through firms’ networks.


  • Trade and firm-level emissions
  • The impacts of the EU ETS on manufacturing firms
  • The disruptive power of natural disasters on trade networks

Geocoded data for Environmental Economists - François Libois

This course will focus on the basic and intermediate requirements that researchers in Environmental Economics have to master when using geocoded data in their work. Data sources include remote sensing information as well as data originating from paper maps of geocoded records.

We will essentially focus on measurement issues and see how choices made in the early steps of the research projects impact the whole research process. The course is very much constructed as a “tricks and tools” to reduce the entry cost in geocoded data and introduce students to Geographical Information System software, namely QGIS, in interaction with statistical software (STATA) and programming language (PYTHON). The course includes many examples from recently published papers, especially on drivers of deforestation, recent trends in agriculture, and tracking of pollution. Participants will get some exercise material to practice around the lectures.


  • Why Geocoded data ?
  • Issues related to the choice of projection systems
  • Measurement issues : pro and cons of (some) remote sensing data, aggregation issues
  • Combining geocoded data with socio-economic data
