Textbook:
I have written a book for this course which is provided in pdf form online. You can download the entire manuscript complete with a mathematical appendix here Microeconomics for Business Decisions Marino.pdf
Below you will find links to each of the separate chapters in the list of
topics. If you prefer, you can download the separate chapters as we progress
through the course.
If you prefer to look at an outside text, the following
book is good.
Pindyck, Rubinfeld;
Microeconomics 9/e, Pearson Prentice-Hall, 2018: ISBN: 978-0-13-418424-1.
This text is expensive, so that those who would like to use
an outside text and save money might consider buying an older edition of Pindyck
and Rubinfeld online.
Grading Scheme, Contact Information, and Web Page Address:
1. Your grade will be based on the following scheme:
SE1 = 50, SE2 = 44, FE = 58.
For this case, the sum of your 3 scores is 152. If we drop
the lowest of the three section exams and weigh the final at 110 (= 60 + 50)
points, your score is
50 + (58/60)110 = 50 + 106.33 = 156.33
Because 156.33
> 152, your point total for the course is 156.33, which rounds to 156.

12/4 Review ---
--- --- Course Description. The main goal of this course is to show how microeconomic
models can be used to guide business decisions. We will study the behavior of consumers and firms, and their
implications for demand, supply and market equilibrium. We will analyze
competitive markets, market failures, and the role of government. To reflect
rising concentration in markets we will spend some time on the implications of
market power on firm pricing decisions and profits. The course also introduces
basic principles of game theory and competitive strategy. This course is designed to prepare students for future business courses,
including finance, marketing, and strategy. The models, methods, and case
studies have been selected with a focus on business relevant applications. For
example, the economics of consumer choice underlies much of modern marketing
strategy, including pricing, segmentation and advertising. The theory of the
firm contributes to a sound understanding of cost accounting as well as
production decisions. Economic analysis of intertemporal decisions and behavior
in a risky environment form the foundation of finance. Finally, the study of
market failure and industrial structure is necessary for an understanding of
government's role in a market economy and the political environment for
business. More generally, this course provides a rigorous foundation
for the study of decision making problems within firms. The student who
successfully completes this course should be able to apply microeconomic
analysis to issues of real world interest within the firm. Slides Practice Problems
