Course Overview

 

This course covers several important and interesting actuarial topics in the areas of stochastic processes, risk theory, and financial economics. In the first part of the course (after a quick review of probability and statistics), we will discuss stochastic processes, which involve the evolution of random variables over time. Specific topics here include Markov chains, Poisson processes, and Brownian motion. This material is critical for understanding advanced actuarial and financial material-for example, the Black-Scholes option pricing model. This is followed by brief discussions of two areas of application of stochastic processes: risk theory and stochastic simulation.

 

In the second part of the course, we cover certain topics in financial economics (in particular, option pricing theory) with emphasis on mathematical modeling and understanding. Our goal is to discuss the material on actuarial Exam 3F/MFE. Specific topics include the basics and background of options, put-call parity, binomial option pricing, the Black-Scholes model, and interest rate modeling.

 

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.

 

Tentative Course Schedule

 

Some key dates for the class are noted below:

 

August 26 (Tuesday)

First day of class: Introduction and Motivation

September 25 (Thursday)

Exam # 1

October 30 (Thursday)

Exam # 2

December 9 (Tuesday)

Last day of class

December 16 (Tuesday, 8 am)

Exam # 3 (Final Exam)

 

In most non-exam weeks, there will be a homework assignment and one or more short in-class assignments. In addition, practicing actuaries will occasionally be invited to give guest presentations to the class during the semester.

 

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. 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.
