Interactive Demo
Production & Cost Lab
Production & Cost Lab is a free, interactive learning demo from the AP Microeconomics course on Lykke. It helps you build intuition for The Law of Diminishing Marginal Returns, Short-Run vs. Long-Run Costs, Marginal Cost and Average Total Cost, Profit Maximization (MR=MC). Play with it directly in your browser — it features 1 slider. This demo lives in the “Unit 3: Production, Cost, and the Perfect Competition Model” section of the course.

How to use this demo
- Drag the “Labor (L):” slider to change the inputs and watch the result update live.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- The Law of Diminishing Marginal Returns
- Short-Run vs. Long-Run Costs
- Marginal Cost and Average Total Cost
- Profit Maximization (MR=MC)
- Perfect Competition Characteristics
- Long-Run Equilibrium and Efficiency
Frequently asked questions
What does the Production & Cost Lab demo do?
Analyze firm behavior and cost structures, leading to the study of the perfectly competitive market model. Production & Cost Lab turns that idea into something you can manipulate directly and watch respond.
What AP Microeconomics concept does Production & Cost Lab teach?
Analyze firm behavior and cost structures, leading to the study of the perfectly competitive market model. It focuses on The Law of Diminishing Marginal Returns, Short-Run vs. Long-Run Costs, Marginal Cost and Average Total Cost, Profit Maximization (MR=MC), Perfect Competition Characteristics, Long-Run Equilibrium and Efficiency from the “Unit 3: Production, Cost, and the Perfect Competition Model” section.
What can I control in Production & Cost Lab?
The “Labor (L):” slider change the key inputs. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does Production & Cost Lab fit into the AP Microeconomics course?
AP Microeconomics is an introductory college-level course that examines the principles of economics applying to individual decision-makers, including consumers and producers. The curriculum focuses on the nature and fun… This demo is the interactive piece for the “Unit 3: Production, Cost, and the Perfect Competition Model” section.

What will I understand better after using Production & Cost Lab?
You'll build intuition for The Law of Diminishing Marginal Returns, Short-Run vs. Long-Run Costs, Marginal Cost and Average Total Cost, Profit Maximization (MR=MC), Perfect Competition Characteristics, Long-Run Equilibrium and Efficiency — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on AP Microeconomics alone.
