Course Assessment Guidelines and Fundamentals of Perfectly Competitive Market Models

Course Assessment Policies and Logistics

  • Assessment Objectives & Learning Process:

    • Course assessments evaluate both class discussion content and reading comprehension from textbook assignments.

    • Lectures may occasionally lag behind assigned homework; self-teaching and familiarizing oneself with concepts via the textbook prior to class instruction is an intentional learning framework.

    • Subsequent class time is utilized to clarify complex concepts and address specific student struggles.

  • Homework Guidelines and Submission Specifications:

    • Homework assignments are directly grounded in the textbook reading, class exercises, and textbook problem sets.

    • All homework assignments are posted on Brightspace.

    • Submission options:

    • Print out the assignment, complete all work by hand, and upload the completed document back to Brightspace.

    • Complete the assignment digitally on an iPad, ensuring all work is shown, and upload to Brightspace.

    • Explicitly showing step-by-step work is mandatory for all submitted solutions.

    • Supplemental practice questions can be posted upon request if additional practice is desired.

  • Weekly Quiz Structure and Execution Protocol:

    • Duration and Timing:

    • Quizzes occur weekly and adhere to a strict schedule with a fast start at 8:00 AM sharp and a hard stop.

    • Total time limit is 5 minutes.

    • Designed completion time for students who have mastered the homework is 2.5 minutes (or 2.5 to 3 minutes).

    • Requiring close to the full 5-minute allocation indicates partial uncertainty; the built-in time pressure serves to measure topic mastery.

    • Format and Content:

    • Quizzes are significantly shorter than homework assignments.

    • At 8:00 AM sharp, a slide is displayed featuring a word problem, requiring immediate reading of several sentences.

    • Content types include core definitions (explaining a key concept in 1 to 2 sentences), graphing, and basic mathematical calculations.

    • Quizzes function as ongoing benchmarks and learning assessments without heavily weighting overall course grade totals.

    • Required Materials and Testing Conditions:

    • Students must bring their own physical paper along with a pen or pencil.

    • Calculators and mobile phones are strictly prohibited.

    • Mathematical items test conceptual understanding rather than arithmetic speed; arithmetic is straightforward and does not require calculation technology.

    • Preparation Strategy:

    • Arrive early to prepare mentally and engage in casual conversation with peers prior to 8:00 AM to stimulate cognitive performance.

    • Quiz results serve as a direct springboard for immediate post-quiz class discussions to address lingering student questions.

  • Scope of Coverage and Midterm Preparation:

    • Quizzes are largely derived from homework problems, specifically covering Chapter 3.

    • Students are expected to complete the full assigned reading for Chapter 3.

    • Mastered comprehension of Chapter 3 is critical, as the upcoming midterm exam will cover Chapter 3 in its entirety.

Fundamentals of Economic Modeling and Perfect Competition

  • Elements of Economic Models:

    • Firms represent one constituent component/element within economic models.

    • Perfectly competitive markets function as a foundational benchmark institution in economic theory.

  • Core Assumptions of Perfect Competition:

    • Homogeneous Products:

    • All firms in the market produce identical, standardized goods.

    • Example: treating all pens as completely identical to one another, or all pencils as identical to one another.

    • Free Entry and Free Exit:

    • Markets have zero barriers to entry or exit.

    • Contrast with institutional entry barriers: intellectual property laws (such as patent protection) legally prohibit competitors from mimicking a product idea, even when physical replication is trivial. Under pure perfect competition, no such legal or institutional barriers exist.

    • Atomistic Market Structure:

    • The market consists of a large number of small firms and a large number of small consumers/households.

    • Every individual seller and buyer represents an insignificant fraction of total market volume.

  • Profit Maximization and Price-Taking Behavior:

    • Because an individual firm is small relative to the aggregate market, its individual output decisions have no influence on overall market supply.

    • Consequently, individual firms cannot affect or influence market price.

    • When making output decisions to maximize profit, a firm must treat market price as an unalterable exogenous variable (price-taking behavior).
