Study Notes

Supply and Demand

Supply is the total amount of a good or service that producers are willing to sell at different prices.
The supply curve slopes upwards, meaning that producers are willing to produce more units as the price increases.
A decrease in oil prices would likely lead an independent oil producer to reduce their production.

Changes in Supply and Quantity Supplied

A change in supply refers to a shift in the entire supply curve, caused by factors like changes in input costs, technology, or government regulations.
A change in quantity supplied refers to a movement along the existing supply curve, caused by changes in the price of the product.

Production Costs and Revenue

Employee training can increase productivity.
The relationship between price and quantity supplied illustrates the elasticity of supply.
Elasticities measure the responsiveness of supply or demand to changes in price.
The production function shows how input changes affect total output.
Short-run production analysis examines the effects of variable inputs on output.

Stages of Production

The marginal product of the second worker is 140 sandwiches.
The total product of three bakers is 27 loaves of bread.
Stage I of production: Each new worker adds more output than the previous one (increasing marginal returns).
Stage II: Marginal returns begin to diminish as more workers are added.
Stage III: Hiring is suspended because adding more workers leads to negative marginal returns.

Costs and Revenue

An executive director's salary is a fixed cost.
Marginal cost is the additional cost of producing one more unit.
Marginal revenue is the additional revenue generated from selling one more unit.
Profit-maximizing output occurs when marginal cost equals marginal revenue.

E-Commerce

E-commerce can be used to reach more customers and reduce costs.
