Study Notes

Supply and Demand

Increase in suppliers: A rise in the number of suppliers in an industry causes the supply curve to shift rightward.
Price increase effect: An increase in the price of one good (e.g., milk) generally results in a rightward shift of the demand curve for a related good (e.g., cheese) as consumers substitute.

Game Theory

Dominant strategy: A dominant strategy is a strategy that yields the best outcome for a player, regardless of the actions of other players.

Production Functions and Costs

Perfect substitutes: If capital and labor are perfect substitutes in a production function, the isoquants (curves showing combinations of inputs that produce the same output) are downward-sloping straight lines.
Increasing returns to scale: A production function exhibits increasing returns to scale when proportional increases in all inputs lead to a more-than-proportional increase in output.

Monopoly

Profit maximization in monopoly: A profit-maximizing monopolist sets the quantity where marginal revenue equals marginal cost. The price will be based on the demand curve at the chosen quantity.

Elasticity and Consumer Choice

Inferior good elasticity: The income elasticity of demand for an inferior good is negative.
Linear demand curve elasticity: A linear demand curve becomes less elastic as the price falls.
