Film Franchises and the Edwards-Buckmire Model: An Examination of the Financial
Performance of Movie Sequels
Jacob Ortega-GingrichAdvisor: Ron Buckmire

Objectives
Two Parts of Project Confirm that Edwards-Buckmire Model in its current
unmodified state is is capable of modeling the post-release behavior of sequels with the same degree of accuracy as with original non-sequels.
Examine how observed trends between the performance of sequels and their parent films can allow for better a priori prediction of the behavior of hypothetical future sequels

Project Summary
Confirmation that EBM models sequels with a similar degree of accuracy as non-sequels
confirms that post-release behavior of sequels is identical to that of original non-sequels
Method of a priori approximation of a sequel's behavior
relationship between A(0) and W A(0) can be estimated for a sequel using the value of b
from the parent film.
