Learning objectives
In an ever increasing number of contexts, it is advisable that a graduate student in
Economics is able to use quantitative measurements and tools. The main objective
of this course is to provide the student the basic mathematical instruments to
construct simple models for economic problems and take informed and justified
decisions.
At the end of the course, the student
should:
- understand and properly treat the main models
presented in the course;
- be able to analyze, formalize and solve practical (economical) problems;
- show good skills in making judgement;
- clearly communicate what he/she has learned using an appropriate language.

Teaching methods
Oral lectures.
During the classes, a theoretical exposition of the contents of the course will be
given.
Then, a great number of examples and exercises will be discussed, with a particular
focus on economic applications. The students will be asked to discuss and propose
possible solutions to the exercises.
On the Elly platform the detailed program and the exams of the previous years will be uploaded at the beginning of the course. To download the material, registration to the online
course is required
Assessment methods and criteria
Written exam.
During the exam, the student can use a scientific
calculator. Graphic calculators, smartphone, tablet,
laptops and smartwatch are not allowed.
The knowledge and the skill in comprehension will
be tested through three questions about elementary
mathematics (1), a problem (2) and three theoretical
questions (3).
The quality of learning, the skill in the applications of
the concepts
and the independence of judgement will be verified
through the economic problem (2). In order to solve
such a problem, the student will individuate an
opportune mathematical model, by obtaining the
solution through the analytical tools presented in
Course.
The use of an appropriate technical language will be
checked through three open questions (3) about the
theoretic subjects of the Course.
Indicative marks:
(1): 3/30
(2): 15/30
(3): 12/30
If the exam is excellent (for completeness,
brightness and organization of the answers,
concepts not specifically treated in the course), it is
valuated with full marks cum laude.
The teacher reserves the right to complete the exam
with an oral test, if
necessary.
Results will be communicated to the students within 10 days, via Esse3. The solution of the exam will be uploaded on the Elly platform within 7 days.
