1. Presentation of the subject

Microeconomics I is the first subject of the training cycle in Economic Theory. Its importance and, at the same time, complexity arises from the fact that it is the first time the student becomes familiar with current economic models. Over the course the student will learn all the basic economic models of consumer theory, production theory, and partial equilibrium. 

The course requires basic mathematical skills and basic knowledge of economics. As the subject requires a change in the way of thinking (from real events to models and the other way round) it can be considered as the learning of a new language. 

The Bologna methodology attempts the learning process to be continuous, which facilitates both student preparation and teaching. To think that in this course it is possible to jump steps is like thinking that in the learning process of a language one can skip steps and then want to write essays.

Requirements to follow training route

This course teaches a new approach to the analysis of economic phenomena. Its importance stems from the fact that it teaches how to build the first mathematical-economic models.

This course can be considered the foundation for the understanding of all the theoretical subjects in the following years. It also constitutes the first part of the training cycle in Economic Theory.

The basic skills required to start the learning process in this subject are: 

1.    Knowledge of the economic reality. Besides the skills acquired during the studies it is necessary that the student knows the economic reality by their own.

2.    Ability of abstraction of the most important microeconomic phenomena. It is necessary to filter information in order to create simplified models.

3.    Ability to relate the results of mathematical models with the actual facts.

4.    Ability to contrast the model results with actual results, with the aim of improving the model. 

The background needed to follow this course can be divided in two groups:

1.    Basic mathematical skills: Algebra, Geometry, Trigonometry, Function Analysis, Optimization.

Most of these skills are basic and are obtained before the student's access to college. Given that the subject requires a good mathematical background, it is recommended for students with a weak mathematical background to try to strength it as soon as possible.

Some of the topics require some mathematical tools that are taught at the same time in a different subject (Mathematics III). This is not a problem, since there is an alternative way of solving problems. The student who wants to apply these mathematical tools in the exam, can do it.

2.    Basic economic knowledge.

In the course Introduction to Economics, during the first term of first year, the student learns to analyze economic phenomena. Microeconomics I builds on this knowledge to show how to build models of the economic reality. 

In-depth and constructive knowledge of Microeconomics I allows the student to access the rest of the studies with a solid foundation.

Learning Objectives

The ultimate goal of this course is that students are able to understand and learn to work with economic models. Through the training route, the student becomes familiar with the process of construction and solution of these models. At the end of this process the student must be prepared to build such models, specifically models of consumer theory, theory of the firm and partial equilibrium. Such models are the basis for the rest of the cycle in Economic Theory.
