Course Overview

 

This course covers several important and interesting actuarial topics in the areas of stochastic processes, risk, and financial economics. The course will largely focus on the mathematics and economics underlying the pricing of financial options. As part of this focus, we will discuss stochastic processes, which involve the evolution of random variables over time; in particular, we will explore Brownian motion as a modeling framework for financial and economic processes. Ultimately, this leads to ideas and techniques critical for understanding advanced actuarial and financial risk management material, such as the Black-Scholes option pricing model, and delta-hedging. Other important topics covered in the course include stochastic simulation of economic and financial variables, and the modeling of interest rates.

 

Overall, our goal is to explore the material relevant to professional actuarial Exam 3F/MFE.

 

Accessibility Statement

 

To insure that disability-related concerns are properly addressed throughout the semester, students with disabilities who require reasonable accommodations to participate in this class are asked to contact me within the first two weeks of class.

 

Honors Projects

 

For those involved in a Campus or College honors program, such as James Scholar, you are welcomed to perform an honors project in association with this class. Such a project would involve an opportunity for undergraduate research relevant to actuarial science. Please let Prof. Gorvett know of your interest in the first few weeks of the class.

 

Grading

 

Course grades will be determined based on the following weights:

 

Homework assignments

20 %

In-class/other assignments

5 %

Group Project

10 %

Exams 1 and 2

40 % (20% each)

Final Exam

25 %

 

Exams may not be made up or taken at different times, except in extremis. In general, the grade weight for a missed exam (provided there is a valid excuse) will accrue equally to any remaining exams. A missed in-class or homework assignment may not be made up; however, the lowest homework score, and the lowest two in-class assignment scores, will be dropped when determining those parts of your grade. Class attendance is expected; serious attendance problems may result in a grade lower than that indicated by the weighting system above.

 

Please note that the final exam schedule is prescribed by the university; in general, instructors are not permitted to change the final exam timing of their courses.

 

Graduate students taking this class for four hours of credit will be required to complete one additional project. Performance on this project may impact the overall grade.
