Long Run Supply and Demand
Explores what happens in a labor market long term: ie, what causes changes once a short term equilibrium has been reached.
Firms Profit Maximizations
A mathematical example showing how a firm maximizes profits from its production function. Uses simple calculus (one derivative). The problem is about a fisherman who employs himself and has some fixed and variable costs.
Production Functions and Cost Curces
Introduces different types of cost curves as well as the production function. A little information on externalities.
Tariffs, Subsidies, and Externalities
Models government subsidies, tariffs, and externalities. Second page is a little blurry but still legible.
Consumer and Producer Surplus; Price Controls
This document defines consumer and producer surplus, showing it on a graph and giving mathematical examples. It has a description of supply elasticity on a graph. It also shows the effects of government price controls on a graph, as well as showing a graph of a tax.
Supply and Demand Elasticity
These notes show a simple problem with a shift in the demand curve. It also defines and gives formulas for demand elasticity, as well as giving examples. These notes are a little messy, but get clearer on later pages.
Supply and Demand Model
Includes a mathematical problem using a utility and value function. It also defines supply and demand, and does a simply problem with that as well.
