This course covers mainly microeconomic theory and its application, particularly for civil engineers. It deals with both theories and examples for mainly transportation infrastructure. They are important for infrastructure planners, designers, engineers, and managers, who are concerned with planning, policy, and management. For instance, in planning transportation infrastructure, an economic assessment of projects is often made on the basis of economic theory, while in transportation policy debates, potential economic impacts could be seriously examined using the knowledge of transportation economics. Many of the topics introduced in this course will be presented at basic to intermediate levels. To have the knowledge and/or understandings about the basic theory of microeconomics is highly recommended.
