The subject Principles of Economics introduces the student into the rudiments of economic analysis so she (he) can start to think as an economist. To achieve this, a complete overview of the economic system is given. It is explained how individual agents relate to each other (consumers and producers) and how their interactions in the market give rise to economic aggregates at the macro level (production of goods and services, price levels, distribution of income). Emphasis is placed on consumer choice (demand) and producer supply in an institutional framework (laws and governments) conditioning their decisions and facilitating exchange relations. Skills: - Identify, organize and analyze relevant economic information in a critic and systematic way. - Clearly state economic problems assessing their scope and advancing viable solutions. - Understand the relationship between economy and society in a world strongly influenced by technological progress and climate change. Attitudes: - Respect for economic facts as a basis for decision making both in private and public policies. - Interest in other persons' ideas and willingness to express own opinions with grounds on empirical references. - Enthusiasm to take advantage from training and entrepreneurship opportunities throughout professional life.

The teaching methodology is based on two types of sessions: 1. Master classes, where the subject is given with graphical support (slides). To facilitate learning the students have access to audiovisual materials and basic texts of reference to complete and deepen the topics explained in class. 2. Practical classes to smaller groups of students, where they can take a more active part in solving the proposed exercises. In these classes student¿s participation and solving of problem sets are graded (¿continuous assessment). Student participation in class enables them to analyze problems and communicate solutions, encouraging the exchange of opinions.
