The emphasis is on understanding and analyzing fundamental documents and concepts in economics, commerce, marketing and accounting in a French-speaking context. The thematic structure includes authentic examples from the economic press, along with the study of essential business contracts such as sale-purchase, representation, credit, insurance and rental contracts. These contracts are analyzed and exploited in specific case studies to give students a practical perspective on economic topics. Individual study is supported by consultation of the recommended specialized bibliography and by applied activities, which contribute to the consolidation of the acquired knowledge.
