L&E: Economic Naturalism

Shows the relationship between the price of a good and the quantity consumers are willing to buy. It typically slopes downward, reflecting that people buy less as prices rise.

Represents the relationship between the price of a good and the quantity producers are willing to sell. It generally slopes upward, as higher prices incentivize more production.

Refers to how strongly the quantity demanded or supplied responds to price changes. High sensitivity means consumers or producers react strongly to even small price shifts.

A market structure where many buyers and sellers exist, products are identical, and no single actor can influence the market price. Firms in perfect competition are price takers.

The point where the supply and demand curves intersect, determining the price and quantity at which the market clears. At this point, there is no excess supply or demand.

Limits on how much a firm can produce due to physical or resource limitations. When a firm hits capacity, it cannot increase output without expanding facilities or operations.

A supply curve with a "step" shape reflects fixed production capacities across producers. Each step represents the entry of a higher-cost producer as demand increases.

The producer whose costs are highest among those currently in the market. This producer sets the market price in competitive markets, as others must match or beat that cost.

Graphs showing a firm’s production costs at different output levels, including fixed, variable, and total costs. They help firms determine the most efficient scale of operation.

Cost advantages that firms experience as they increase production. Larger scale leads to lower per-unit costs due to factors like specialization and bulk purchasing.

The smallest production size at which a firm can achieve the lowest average cost. Below this scale, per-unit costs are higher due to underutilised resources.

A market where a single firm can supply the entire demand at a lower cost than multiple competing firms. This usually occurs when economies of scale are so large that competition is inefficient.
