Microeconomics Concepts and Formulas

Jacob Clifford guides students through key microeconomics equations essential for exams. He emphasizes the importance of understanding and practicing these equations, covering topics like short run cost curves, profit calculation, consumer and producer surplus, elasticity, and the least cost and utility maximizing rules. The video encourages students to practice using a provided sheet and highlights the need to show work in AP exams.

What is the main focus of the video tutorial?

• Graphs in microeconomics

• Key equations for microeconomics exams

• History of economics

• Economic policies

Which of the following is NOT a short-run per unit cost curve?

• Total revenue

• Average total cost

• Average variable cost

• Marginal cost

What is the equation for marginal cost?

• Total cost divided by quantity

• Change in total cost divided by change in output

• Total revenue minus total cost

• Price times quantity

How is profit calculated in microeconomics?

• Price minus average fixed cost

• Total cost minus total revenue

• Average total cost minus average variable cost

• Total revenue minus total cost

What is the formula for calculating consumer surplus?

• Total cost divided by quantity

• Base times height

• One half base times height

• Price times quantity

Which equation is used to calculate deadweight loss?

• Average total cost minus average variable cost

• Price elasticity of demand

• Total revenue minus total cost

• One half base times height

Which of the following is NOT a type of elasticity discussed in the video?

• Price elasticity of demand

• Supply elasticity

• Cross-price elasticity

• Marginal elasticity

What is the least cost rule in microeconomics?

• Maximizing output while minimizing cost

• Minimizing output while maximizing cost

• Equalizing the marginal product of labor and capital

• Maximizing utility per dollar spent

What does the utility maximizing rule suggest?

• Consume more of the good with higher utility per dollar

• Consume less of the good with higher utility per dollar

• Equalize the utility per dollar spent across goods

• Maximize total utility regardless of cost

What is the correct formula for elasticity?

• Percent change in price divided by percent change in quantity

• Percent change in quantity divided by percent change in price

• Total cost divided by total revenue

• Price times quantity
