Objectives

The aim of this course is to understand the basic tools of microeconomic analysis and to become proficient in their use.

We will focus on Consumer Theory (preferences, utility, consumption and demand).

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Final Exam 50 % 1 0.04 CM24, CM25, CM27, CM28, KM22, KM26, SM23, SM25, SM27, SM29
Tests during the semester 50 % 1 0.04 CM24, CM25, CM27, CM28, KM22, KM26, SM23, SM25, SM27, SM29

This subject/module does not provide for a single assessment system.


Assessment process The assessment process includes both tests during the semester and a final exam.

  • Tests during the semester (50% of the final grade)
  • Includes a partial test, which will account for 26% of the final grade.
  • Also includes one or more additional activities/tests (written or oral) which, in total, will account for the remaining 24%. Details will be announced via the Virtual Campus before the start of the semester.
  • Final exam (50% of the final grade)


Tests and exams:

  • May include questions on all content covered in class, as well as the content of the textbook, videos, and all material published on the Virtual Campus.
  • May include open-ended or multiple-choice questions and may be written or oral. Rescheduled tests/exams are, by default, oral.


In accordance with current academic regulations, the teaching staff may lower a student's grade by up to 2 points out of 10 in the event of failure to comply with conduct regulations during classes, tests, or exams.

Non-assessable: A student shall be considered "Non-assessable" (No avaluable) in the subject provided they have not participated in any of the assessment activities. Therefore, a student who completes any component of continuous assessment can no longer opt for a "Non-assessable" status.

Use of AI: In this subject, the use of Artificial Intelligence (AI) technologies is not permitted in any phase.


Assessment schedule

The dates of the different assessment tests (classroom exercises, submission of assignments, etc.) will be announced with sufficient notice during the semester. The date of the partial exam and the final exam is programmed in the Faculty's exam calendar.

"The schedule of assessment tests may not be modified, unless there is an exceptional and duly justified reason for which an assessment cannot be carried out. In this case, those responsible for the degree programmes, having consulted the teaching staff and the affected students, shall propose a new schedule within the corresponding teaching period" (Section 1 of Article 264, UAB Academic Regulations).

Students who, in accordance with the previous paragraph, need to change an assessment date must submit their request using the following form: https://eformularis.uab.cat/group/deganat_feie/nou-reprogramacio-de-proves


Grade review procedure

We will announce in due time the when and how final grades will be published. Likewise, information regarding the procedure, location, date, and time for exam reviews will be provided in accordance with University regulations.


Resit process

"To participate in the resit, students must have previously been assessed in a set of activities whose weight is equivalent to a minimum of two-thirds of the total grade of the subject" (Section 2 of Article 261, UAB Academic Regulations). Students must have obtained an average grade for the subject of 3.5 or higher and less than 5.

The date of this test will be programmed in the Faculty's exam calendar. The resit exam grade is qualitative, with two possible results: 'pass' or 'fail'. In the case of a 'pass', the grade that will appear on the transcript is a 5. In the case of a 'fail', the final grade will be the same as it was before the resit exam.


Irregularities in assessment acts

Any irregularity committed during any test, exam, or submission of practical work —which includes having access to prohibited material (documents, electronic devices, etc.) even if they have not been used— will result in the immediate failure of that assessment. Likewise, being caught with any electronic device during a test or exam, regardless of whether it was attempted to be used or not, will result in the direct failure of the entire subject.

The completion of assessment activities is subject to this teaching guide, as well as the "Faculty of Economics and Business Policy on the detection of irregularities during the completion of assessment activities". Students are advised to consult its content.
