This course builds on ECO201 to go beyond the competitive equilibrium setting and introduce new causes of market failures. We aim to study how the presence of incomplete and asymmetric information affects the standard analysis of microeconomic theory. The starting point is that asymmetric information leads to market failures, which opens the question of how to regulate and appropriately design markets to solve or reduce these failures. We will present the basics of two important theories and methods which have been the core of the modern microeconomic analysis since 1970: signaling games and mechanism design. The students will learn new tools to analyze markets and interactions in the presence of incomplete and asymmetric information. They will also learn how to develop policy tools and design markets that mitigate the issues induced by the information structure.
The mathematical treatment is rigorous, but not as much as for a graduate-level course. This course will be thus most useful as a preparation for formal graduate studies in economics.

This course will cover fluctuations, unemployment, economic crises, and macroeconomic stabilization policies through the lens of the “New Keynesian” model that has developed over that past couple of decades and now guides short-run macroeconomic analysis. After reviewing the building blocks of the short-run macroeconomic model (namely, aggregate demand and supply), we will cover conventional monetary and fiscal policies, and then turn to the unconventional policies that are put in place during “liquidity traps”, i.e. situations wherein conventional monetary policy is unable to efficiently restore aggregate demand (as is currently still the case in the euro area). We will occasionally look into the historical record - from the Great Depression to the Japanese experience, to the worldwide Great Recession - and structure the evidence by means of a simple macroeconomic model with price rigidities. We will discuss the effectiveness of unconventional monetary policies (forward guidance, quantitative easing), as well as the unconventional effects of fiscal policies, during liquidity traps. Finally, we will examine whether the current trap follows from a serious but temporary shock or reflects a “secular stagnation" episode of persistently low aggregate demand and growth.

Ce cours présente l'économie de la responsabilité sociale des entreprises (RSE) et les facteurs qui incitent les entreprises, agissant sur une base volontaire, à intégrer des préoccupations sociales, environnementales et éthiques dans leurs activités économiques et leurs interactions avec leurs parties prenantes. Il se compose de deux parties. La première partie présente ce qu'est et n'est pas la RSE en économie, et la relation entre la RSE et le risque climatique. La deuxième partie développe la relation entre la RSE et la performance financière, et comment les entreprises réussissent à motiver leurs employés avec la RSE
Textbook:
❯ Corporate Environmentalism and Public Policy by Thomas P. Lyon & John W. Maxwell (Cambridge University Press)
❯ The Market for virtue: the potential and limits for CSR by David Vogel (Brookings institution press)
Evaluation: controle continu + examen final
L'examen final consiste à rédiger un rapport qui analyse un article de recherche scientifique portant sur les thématiques vues en cours. Ce rapport est préparé à la maison sur plusieurs semaines

This course introduces students to the research frontiers in economics. Each week, a researcher from the laboratory CREST would present a central topic of his/her research. Students are expected to see how researchers tackle problems using the tools and concepts developed in economics. Topics include traditional microeconomics, macroeconomics, and econometrics, as well as recent interdisciplinary developments such as blockchain technology, and machine learning.
Together the courses A & B will consist of 8 two-hour lectures by Polytechnique economists presenting their own recent research work.

This course is designed to provide economists with elements of modern scientific computing using the open-source Julia language. It covers several topics in numerical analysis and programming, and applies them to several economic modeling fields (dynamic programming, macro modeling, IO models). Special emphasis is given to performance and reproducibilty. Approximately half of the sessions will consist in hands-on tutorials.

La numérisation des marchés progresse à un rythme de plus en plus rapide, transformant profondément la manière dont les clients achètent des produits et services, ainsi que la manière dont les entreprises interagissent entre elles. La conception des plateformes internet et des protocoles Blockchain soulève de nouveaux défis qui ne peuvent être compris qu'à travers une solide compréhension de l'informatique et des incitations économiques.
Nous explorerons les concepts économiques et les outils informatiques que les étudiants doivent acquérir pour participer à cette transformation. Le cours mettra l'accent sur les Blockchains en raison de leur potentiel disruptif. La structure du cours reflétera la nature interdisciplinaire du sujet.

Experiments are a great way to produce the kind of data required to answer specific economic questions. As a result, the use of experiments in economics has greatly increased over the last three decades. The class will provide a guided tour of noticeable experiments. Some standard experiments will be reproduced during the class and we will debate regarding the economic implications. Along the way, we will address important questions like what is a good descriptive model?, do results from the lab generalize to the field?, or can we predict what kind of experiments would scale up? Last, but not least, experiments are a great way to test and reconsider rationality assumptions often made in economics.
