The aim of this course is to provide the students with a first approach to a rigorous analysis of the micro-economic mechanisms of a market economy. More specifically, the objectives are:

1. Familiarize the students with the basic concepts and the fundamental mechanisms of the micro-economic analysis;

2. Get the students to use those mechanisms and concepts to carry out a rigorous analysis of several "real-life" economic problems and economic policy recommendations;

3. Introduce students to information literacy in order to help students to deal efficiently with information and carry out effective research. Train the students to read critically and synthetize the contents of economic articles/texts.

The chosen methodology is a qualitative and graphical presentation of economic models, so as to draw the students' attention to the explanative power as well as the limits of the modelling approach.

The Economics 1 course will start with a presentation of the economic model of demand and supply in order to provide an analysis of the mechanisms of competitive markets (price determination, equilibrium quantity, etc.). It will also be the occasion to investigate the impact of some public policies such as price control and indirect taxation on the competitive equilibrium.
The course will then determine why, and under which conditions, free trade can be viewed as an efficient way to coordinate the actions of specialized economic agents. Through a careful examination of the (utopic) necessary conditions a market must fulfil to be considered perfectly competitive, it will be brought to the students' attention that those conditions are seldom (if ever) respected: the course will then provide an overview of several market failures, as well as study in detail several types of imperfect competition.
Finally, the question of the possibility (and the necessity) of public intervention in a market economy will remain a central focus throughout the course.

Chapter 4: Consumers, producers and the efficiency of markets (Mankiw, ch. 7, 8)
Chapter 5: Supply, demand and government policies (Mankiw, ch. 6)

Chapter 7: Public goods and common resources (Mankiw ch. 11)

Part IV: Firm behavior in competitive markets
Chapter 8: The costs of production (Mankiw, ch. 13)
Chapter 9: Firms in competitive markets (Mankiw, ch. 14)

Part V: Imperfect competition

Chapter 11: Other examples of imperfect competition (Mankiw ch. 11)

a) Plenary lectures
During the plenary lectures, the professor presents the concepts and mechanisms associated to the different models. Those lectures will follow the course outline presented above.
From a methodological point of view, numerous press articles will be used as bibliographical support beyond the reference book. The objective is twofold: train the students to a careful reading and synthesis of economic texts, as well as draw the students' attention to the omnipresence of economic questions in the public debate.

b) Exercise sessions (TA sessions)
The exercise sessions are carried out in small groups, and aim at checking knowledge acquisition as well as applying the theoretical concepts presented in class to solve exercises and case studies. So as to benefit from those sessions, the students should have reviewed the corresponding lectures. Those exercise sessions will also be partly devoted to critical reading of economic articles.

c) Personal work
Regular personal work is critical for success. As the course goes on, each student is expected to devote sufficient time so as to make sure he/she understands the subjects being treated. The revision period at the end of the semester should not be the occasion to discover the course contents, but rather to strengthen the comprehension of a course that is already known by the student. Personal meetings with the course assistants and the professor can be arranged for the students who specifically ask it.

The final exam is written. It requires a knowledge of the theoretical concepts as well as the ability to apply those concepts to the resolution of applied exercises (similar but not identical to those treated in the exercise sessions) and the analysis of real-life economic problems.
