This course covers mainly basic economic theories and its application, particularly for civil engineers. They are important for infrastructure planners, designers, engineers, and managers, who are concerned with planning, policy, and management of infrastructure. For instance, in planning transportation infrastructure, an economic assessment of projects is often made on the basis of economic theory. On the other hand, infrastructure investment may contribute to the national economic growth through some channels. Furthermore, large-scale infrastructure development may affect the national land structure in the long-run. 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.
