1. Course Details

Summary of Course

Mathematical tools are an important part of theoretical economic analysis. The main purpose of this course is to introduce students to advanced mathematical techniques used in theoretical economic analysis. In addition, the course will provide a stepping stone to Honours programs in economics and related disciplines and to other advanced undergraduate courses.

This course gives students a working knowledge of basic analysis, topology, and static and dynamic optimisation techniques applied in economics. Topics include logic and set theory, topological principles in Euclidean spaces, properties of real-valued functions (continuity, concavity, quasi-concavity), differentiation in multi-dimensional Euclidean spaces, classical optimisation with and without constraints, comparative statics, and envelope theorems. All mathematical techniques are illustrated with mainstream theoretical applications such as consumer theory and game theory.

Please note: due to substantial change in the ECON3202/5402 course materials this year, students are strongly encouraged to test their assumed knowledge prior to commencing the course, by completing the pre-test quiz here (or: https://www.flexiquiz.com/SC/N/Pre-testECON3202).

Communication with staff

You should feel free to contact your lecturer about any academic matter. However, it is strongly encouraged, for efficiency reasons, that all enquiries about the subject material be made at lectures or during consultation time. Discussion of course subject material will not be entered into via lengthy emails.

Email correspondence on administrative matters will be responded to within 48 hours, but not over weekends. Please note that the lecturer has no advance notice of the date and time of the final exam.

Student Enrolment Requests

Students can vary their own enrolment (including switching lecture streams or tutorials) via myUNSW until the end of Week 1. In general, most other student enrolment requests should be directed to The Nucleus: Student Hub (formerly Student Central). These include enrolment in full courses or tutorials, course timetable clashes, waiving prerequisites for any course, transfer-of-credit (international exchange, transfer to UNSW, cross-institutional study, etc.), or any other request which requires a decision about equivalence of courses and late enrolment for any course. Where appropriate, the request will be passed to the School Office for approval before processing. Note that enrolment changes are rarely considered after Week 2 classes have taken place.

3. Learning and Teaching Activities

Approach to Learning and Teaching in the Course

​The philosophy underpinning this course and its Teaching and Learning Strategies are based on “Guidelines on Learning" that Inform Teaching at UNSW".

Specifically, the lectures, tutorials and assessment have been designed to appropriately challenge students and support the achievement of the desired learning outcomes. A climate of inquiry and dialogue is encouraged between students and teachers and among students (in and out of class). The lecturers and tutors aim to provide meaningful and timely feedback to students to improve learning outcomes.

Learning Activities and Teaching Strategies

​The examinable content of the course is defined by the references given in the Lecture and Tutorial Schedules, the content of Lectures, and the content of the Tutorial Program.

Lectures

The purpose of the lectures is to provide a logical structure for the topics that make up the course; to emphasize the important concepts and methods of each topic, and to provide relevant examples to which the concepts and methods are applied. Lecture attendance is essential. This course has been designed to highlight in-class discussions of complex material. In particular, the lecturer will make extensive use of the white-board to discuss, derive and explain mathematical concepts pertinent to theoretical economics.

Tutorials

Tutorials are an integral part of the subject. Tutorial presentations/discussions and questions/problems will build on the material discussed in class with the lecturer.

Out-of-Class Study

While students may have preferred individual learning strategies, it is important to note that outside-of-class learning time is essential to reinforce the concepts developed in lectures and tutorials.

An “ideal” strategy (on which the provision of the course materials is based) might include:

  • Reading of the recommended material before the lecture. This will give you a general idea of the topic area.
  • Attending the lectures. Here the context of the topic in the course and the important elements of the topic are identified and explained. Examples are given, and formal results stated, discussed, and proven.
  • Attempting the weekly homework assignments.
  • Attending and participating in the tutorial sessions to reinforce learning.

The lectures will focus on aspects that are more difficult to understand or apply with the aim of providing greater comprehension and facility. The readings and the lectures give you an opportunity to learn the concepts and methods, see some simple applications and begin the process of learning to use these models on your own.

You will be given homework assignments which are an essential part of the course. The homework assignments present the mathematical methods with statements and proofs of the main theorems and many examples and problems. The assignments will be marked so you will be asked to submit your work. We will discuss the answers in the tutorial sessions and you will be expected to participate in the discussion. Since the problems on the exams will be similar in character to the assigned problems, your serious effort on the homework assignments is a necessary condition for good performance on the exams.

5. Course Resources

​The website for this course is on UNSW Moodle.

Since the emphasis in ECON3202 is in developing formal mathematics as applied to economic analysis, we shall use the mathematical appendix of the following textbook, which will be considered required reading:

  • Geoffrey Jehle and Philip Reny, Advanced Microeconomic Theory, Pearson Education, 3rd edition 2011. (JR)
A more advanced textbook that covers the same material in a more rigorous way, and that will be treated as a recommended textbook is:
  • Rangarajan Sundaram, A First Course in Optimization Theory, Cambridge University Press, 1996.
Additional references for mathematics for economics include:

  • Alpha C. Chiang, Kevin Wainwright, Fundamental Methods of Mathematical Economics, McGraw-Hill Education, 4th ed. 2005, and
  • Simon, Carl P., Lawrence Blume, Mathematics for Economists, W. W. Norton, 1994.

6. Course Evaluation & Development

Feedback is regularly sought from students and continual improvements are made based on this feedback. At the end of this course, you will be asked to complete the myExperience survey, which provides a key source of student evaluative feedback. Your input into this quality enhancement process is extremely valuable in assisting us to meet the needs of our students and provide an effective and enriching learning experience. The results of all surveys are carefully considered and do lead to action towards enhancing educational quality.

​The School of Economics strives to be responsive to student feedback. If you would like more information on how the design of this course and changes made to it over time have taken students’ needs and preferences into account, please contact the Director of Education at the School of Economics.

Program Learning Outcomes

The Business School places knowledge and capabilities at the core of its curriculum via seven Program Learning Outcomes (PLOs). These PLOs are systematically embedded and developed across the duration of all coursework programs in the Business School.

PLOs embody the knowledge, skills and capabilities that are taught, practised and assessed within each Business School program. They articulate what you should know and be able to do upon successful completion of your degree.

Upon graduation, you should have a high level of specialised business knowledge and capacity for responsible business thinking, underpinned by ethical professional practice. You should be able to harness, manage and communicate business information effectively and work collaboratively with others. You should be an experienced problem-solver and critical thinker, with a global perspective, cultural competence and the potential for innovative leadership.

All UNSW programs and courses are designed to assess the attainment of program and/or course level learning outcomes, as required by the UNSW Assessment Design Procedure. It is important that you become familiar with the Business School PLOs, as they constitute the framework which informs and shapes the components and assessments of the courses within your program of study.

PLO 1: Business knowledge

Students will make informed and effective selection and application of knowledge in a discipline or profession, in the contexts of local and global business.

PLO 2: Problem solving

Students will define and address business problems, and propose effective evidence-based solutions, through the application of rigorous analysis and critical thinking.

PLO 3: Business communication

Students will harness, manage and communicate business information effectively using multiple forms of communication across different channels.

PLO 4: Teamwork

Students will interact and collaborate effectively with others to achieve a common business purpose or fulfil a common business project, and reflect critically on the process and the outcomes.

PLO 5: Responsible business practice

Students will develop and be committed to responsible business thinking and approaches, which are underpinned by ethical professional practice and sustainability considerations.

PLO 6: Global and cultural competence

Students will be aware of business systems in the wider world and actively committed to recognise and respect the cultural norms, beliefs and values of others, and will apply this knowledge to interact, communicate and work effectively in diverse environments.

PLO 7: Leadership development

Students will develop the capacity to take initiative, encourage forward thinking and bring about innovation, while effectively influencing others to achieve desired results.

These PLOs relate to undergraduate and postgraduate coursework programs.  Separate PLOs for honours and postgraduate research programs are included under 'Related Documents'.

Business School course outlines provide detailed information for students on how the course learning outcomes, learning activities, and assessment/s contribute to the development of Program Learning Outcomes.

Academic Integrity and Plagiarism

Academic Integrity is honest and responsible scholarship. This form of ethical scholarship is highly valued at UNSW. Terms like Academic Integrity, misconduct, referencing, conventions, plagiarism, academic practices, citations and evidence based learning are all considered basic concepts that successful university students understand. Learning how to communicate original ideas, refer sources, work independently, and report results accurately and honestly are skills that you will be able to carry beyond your studies.

The definition of academic misconduct is broad. It covers practices such as cheating, copying and using another person’s work without appropriate acknowledgement. Incidents of academic misconduct may have serious consequences for students.

Plagiarism

UNSW regards plagiarism as a form of academic misconduct. UNSW has very strict rules regarding plagiarism. Plagiarism at UNSW is using the words or ideas of others and passing them off as your own. All Schools in the Business School have a Student Ethics Officer who will investigate incidents of plagiarism and may result in a student’s name being placed on the Plagiarism and Student Misconduct Registers.

Below are examples of plagiarism including self-plagiarism:

Copying: Using the same or very similar words to the original text or idea without acknowledging the source or using quotation marks. This includes copying materials, ideas or concepts from a book, article, report or other written document, presentation, composition, artwork, design, drawing, circuitry, computer program or software, website, internet, other electronic resource, or another person's assignment, without appropriate acknowledgement of authorship.

Inappropriate Paraphrasing: Changing a few words and phrases while mostly retaining the original structure and/or progression of ideas of the original, and information without acknowledgement. This also applies in presentations where someone paraphrases another’s ideas or words without credit and to piecing together quotes and paraphrases into a new whole, without appropriate referencing.

Collusion: Presenting work as independent work when it has been produced in whole or part in collusion with other people. Collusion includes:

  • Students providing their work to another student before the due date, or for the purpose of them plagiarising at any time
  • Paying another person to perform an academic task and passing it off as your own
  • Stealing or acquiring another person’s academic work and copying it
  • Offering to complete another person’s work or seeking payment for completing academic work

Collusion should not be confused with academic collaboration (i.e., shared contribution towards a group task).

Inappropriate Citation: Citing sources which have not been read, without acknowledging the 'secondary' source from which knowledge of them has been obtained.

Self-Plagiarism: ‘Self-plagiarism’ occurs where an author republishes their own previously written work and presents it as new findings without referencing the earlier work, either in its entirety or partially. Self-plagiarism is also referred to as 'recycling', 'duplication', or 'multiple submissions of research findings' without disclosure. In the student context, self-plagiarism includes re-using parts of, or all of, a body of work that has already been submitted for assessment without proper citation.

To see if you understand plagiarism, do this short quiz: https://student.unsw.edu.au/plagiarism-quiz

Cheating

The University also regards cheating as a form of academic misconduct. Cheating is knowingly submitting the work of others as their own and includes contract cheating (work produced by an external agent or third party that is submitted under the pretences of being a student’s original piece of work). Cheating is not acceptable at UNSW.

If you need to revise or clarify any terms associated with academic integrity you should explore the 'Working with Academic Integrity' self-paced lessons available at: https://student.unsw.edu.au/aim.

For UNSW policies, penalties, and information to help you avoid plagiarism see: https://student.unsw.edu.au/plagiarism as well as the guidelines in the online ELISE tutorials for all new UNSW students: http://subjectguides.library.unsw.edu.au/elise. For information on student conduct see: https://student.unsw.edu.au/conduct.

For information on how to acknowledge your sources and reference correctly, see: https://student.unsw.edu.au/referencing. If you are unsure what referencing style to use in this course, you should ask the lecturer in charge.


Student Responsibilities and Conduct

​Students are expected to be familiar with and adhere to university policies in relation to class attendance and general conduct and behaviour, including maintaining a safe, respectful environment; and to understand their obligations in relation to workload, assessment and keeping informed.

Information and policies on these topics can be found on the 'Managing your Program' website.

Workload

It is expected that you will spend at least ten to twelve hours per week studying for a course except for Summer Term courses which have a minimum weekly workload of twenty to twenty four hours. This time should be made up of reading, research, working on exercises and problems, online activities and attending classes. In periods where you need to complete assignments or prepare for examinations, the workload may be greater. Over-commitment has been a cause of failure for many students. You should take the required workload into account when planning how to balance study with employment and other activities.

We strongly encourage you to connect with your Moodle course websites in the first week of semester. Local and international research indicates that students who engage early and often with their course website are more likely to pass their course.

View more information on expected workload

Attendance

Your regular and punctual attendance at lectures and seminars or in online learning activities is expected in this course. The Business School reserves the right to refuse final assessment to those students who attend less than 80% of scheduled classes where attendance and participation is required as part of the learning process (e.g., tutorials, flipped classroom sessions, seminars, labs, etc.).

View more information on attendance

General Conduct and Behaviour

You are expected to conduct yourself with consideration and respect for the needs of your fellow students and teaching staff. Conduct which unduly disrupts or interferes with a class, such as ringing or talking on mobile phones, is not acceptable and students may be asked to leave the class.

View more information on student conduct

Health and Safety

UNSW Policy requires each person to work safely and responsibly, in order to avoid personal injury and to protect the safety of others.

View more information on Health and Safety

Keeping Informed

You should take note of all announcements made in lectures, tutorials or on the course web site. From time to time, the University will send important announcements to your university e-mail address without providing you with a paper copy. You will be deemed to have received this information. It is also your responsibility to keep the University informed of all changes to your contact details.
