Corso di First cycle degree in ECONOMICS AND MANAGEMENT
Academic year when starting the degree:
2018/2019
Year:
2
Academic year in which the course will be held:
2019/2020
Partizione:
Cognomi A-G
Credits:
9
Period:
Second semester
Standard lectures hours:
140
Requirements:

To be admitted at the exam, students must first pass Matematica.

Final Examination:
Orale

Written exam.
Students can take the exam alternatively with:

One general test.
At the end of the course, during the examination sessions, 90 minutes examinations will be held on the entire course program. To pass the exam, the student must achieve a grade not lower than 18/30 (eighteen). Totals above 30 give the right to honor mark.
The test consists of two parts.
The first is composed of 10 short questions (open or closed answers), also of a theoretical nature. By answering less than 7 questions correctly, the test is not passed. By correctly answering at least 7 questions, the outcome of the second part will be evaluated. By correctly answering more than 7 questions, points will be added to the outcome of the second part:
8 correct questions + 1 point
9 correct questions + 2 points
10 correct questions + 2 points
The second part consists of 3 open-ended exercises, each of which is assessed up to 10 points.

Two partial tests.
At the end of the first cycle of lessons, and at the end of the course, two partial tests will be organized concerning the topics of the part of the course that has just been completed (the first will focus on "calculation of probabilities", the second on "financial calculation"). Each test, evaluated in sixteenths, will last 60 minutes and will be considered passed with a score not lower than 7 (seven). The exam is passed if the sum of the scores of the two tests is not less than 18/30 (eighteen). Totals over 30 give the right to praise.
Each partial test consists of two parts.
The first is composed of 5 short questions (open or closed answers), also of a theoretical nature. Responding correctly to less than 3 questions, the test is not passed. By correctly answering at least 3 questions, the outcome of the second part will be evaluated. By correctly answering more than 3 questions, points will be added to the outcome of the second part:
4 correct questions + 1 point
5 correct questions + 2 points
The second part consists of 2 open-ended exercises, each of which is evaluated up to 7 points.

Students with LD are required to contact the disabilities'support office (servizio.disabili@uninsubria.it) to define the individualized training project to be sent to the course owner within 10 days of each exam session to be taken.

Assessment:
Voto Finale

At the end of the course students should be able to:
a) Construct common financial contracts, such as leasing contracts, consumer credit and loans;
b) Compute some legal indicators linked to financial contracts, such as TAN, APR, ISC;
c) Evaluate the convenience of some financial transactions according to the most accredited criteria that allow the maximization of profit in a given time horizon;
d) Critically comment on criteria inconsistent with the goal of maximizing profit as set time horizon;
e) Compute prices and yields of main fixed income securities, as well as the Duration and the underlying term structure;
f) Apply basic probability to managerial and financial problems

The course will be held with lectures in which we will discuss the theoretical arguments and the methods of solution of the exercises. During classes, exercises will be proposed both for self assessment and class work.
Main topics cover:
• Probability: different approaches to the definition and study.
• random experiments, events, probability, Bayes' Theorem.
• Capitalization and discounting: financial laws, financial laws in one and two variables.
• Standard Financial Contracts: depreciation, leasing and installment plans.
• legal indicators: TAN, APR, ISC.
• Financial valuations of non random investments.
• Term structure of interest rates and fixed-income securities.
• Financial immunization.

Attendance is not mandatory, though highly recommended. Nevertheless, it is compulsory to study course material through textbook. The adopted texts are:
1.E. CASTAGNOLI, L. PECCATI, Matematica in azienda 1 (Calcolo finanziario con applicazioni), Milano, Egea, 2010.
2.E. CASTAGNOLI, M. CIGOLA, L. PECCATI, Probability. A Brief Introduction, Milano, Egea, 2009.

The course will take place with lectures in which the theoretical topics and the methods of solution of the exercises will be discussed. During the lessons exercises can be assigned both for individual study and to solve in the classroom.
Exercises’ sessions will be held during the semester.
