Course Syllabus

Abstract

Economic theory is a one-module undergraduate course, which combines a brief introduction to the standard methodology of economics with an overview of the essential models of mainstream micro- and macroeconomics. It’s intended to give students an overview of the economic models that describe the behavior and interaction of individual consumers and firms, formation of prices in various market structures, and the real-life problems of economic inefficiency caused by market failures as well as macroeconomic issues of aggregate product and national income determination, unemployment, inflation, economic growth and the main instruments and consequences of fiscal and monetary policy.
Learning Objectives

Learning Objectives

  • The course is meant to familiarize the students with the essential toolkit of economic analysis instruments and teach them to apply these for answering specific questions about peoples', firms' or governments' decisions about resource allocation.

Assessment Elements

Assessment Elements

  • non-blocking In-class quizzes
    In-class quizzes require students to answer short (typically, maximal time allowed is 5 minutes) questions dealing with the contents of the preceding lecture. There will be no make-ups for missed quizzes. But, if a quiz has been missed for an objective, documentally verified reason registered with the study office, its weight in the final grade will be transferred to other quizzes this student has written.
  • non-blocking Final end-of-module exam
    The exam is a written paper, consisting of several short, free-response questions and two longer free response problems. The assignment will be published on Piazza ("resources" section), the platform that has been used for all teacher-student communication throughout the course. Total duration of the exam is 120 minutes (100 minutes to write down the answers + 20 minutes to photograph them and send them to your classteacher's email - exactly the same way that you did with the first, "home assignment" part of the exam).
