Questions and Answers

Equilibrium in a competitive market results in the economically efficient level of output where

marginal benefit equals marginal cost

What explains why the ATC and marginal cost curves are U-shaped in the short run

The law of diminishing returns states that as production increases, marginal costs initially decrease due to specialization and increasing returns to scale. However, beyond a certain point, diminishing returns set in, causing marginal costs to rise, hence the U-shape of the curves.

A market demand curve reflects the:

aggregate preferences of consumers for a product.

Study Notes

Market Equilibrium and Efficiency

  • Equilibrium in a competitive market results in the economically efficient level of output.

Cost Curves

  • The Average Total Cost (ATC) and Marginal Cost (MC) curves are U-shaped in the short run due to diminishing returns and increasing marginal costs.

Demand Curve

  • A market demand curve reflects the quantity of a good or service that all consumers are willing and able to purchase at a given price level.

Monopoly

  • One true statement about monopoly is that a single firm produces the entire market output.

Public Goods

  • Private producers may be disinclined to supply public goods because they are non-rivalrous and non-excludable, making it difficult to charge for them and recover production costs.

Opportunity Cost

  • The opportunity cost of buying a latte is the next best alternative that is given up, which is the value of the chocolate chip cookie that could have been purchased instead (in this case, 2 cookies).

Production Possibility Frontier

  • An inward movement of a nation's production possibility frontier can be caused by a decline in factors of production, technological regress, or an increase in unemployment.

Comparative Advantage

  • You have a comparative advantage when you can produce a good or service at a lower opportunity cost than someone else.
  • Australia has a comparative advantage in the production of goods such as minerals, coal, and agricultural products.
