Principles of Business Economics Quiz

Microeconomics studies the allocation of resources and decision-making at the individual level, with supply and demand being a core principle determining prices and quantities in markets.

The law of demand asserts an inverse relationship between price and quantity demanded, stating that as the price of a good decreases, consumers tend to buy more of it.

GDP measures the total value of all goods and services produced in a country, serving as a key indicator of its economic performance.

Total revenue is calculated by multiplying the price of a good or service by the quantity sold, representing the overall income generated by sales.

Ceteris paribus is a Latin phrase meaning 'all other things being equal,' used in economic analysis to isolate the impact of a specific variable while keeping other factors constant.

The law of supply asserts a positive relationship between the price of a good and the quantity supplied, indicating that producers are more willing to supply at higher prices.

Perfect competition is a market structure with a large number of buyers and sellers, where no single participant has significant market power.

Opportunity cost represents the value of the next best alternative that must be forgone when a decision is made, highlighting the trade-offs involved.

Elasticity measures the sensitivity or responsiveness of the quantity demanded to changes in price, indicating how consumers react to price fluctuations.

Positive externality occurs when the benefits of a good or service spill over to third parties; education, by improving societal knowledge and skills, is a classic example.

Government intervention addresses market failures by enforcing rules, ensuring fair competition, and correcting externalities or other inefficiencies.

The law of diminishing marginal utility states that as a person consumes more units of a good, the additional satisfaction or utility derived from each additional unit decreases.

Factors of production include land, labor, capital, and entrepreneurship; technology is a facilitator or input but not a primary factor.

Price elasticity of demand is computed by dividing the percentage change in quantity demanded by the percentage change in price, providing insights into consumer responsiveness.

A perfectly elastic demand curve is horizontal, indicating that consumers are willing to buy any quantity at a constant price; small price changes lead to infinite quantity changes.

Elasticity of supply is computed by dividing the percentage change in quantity supplied by the percentage change in price, indicating how producers respond to price fluctuations.

The law of diminishing returns states that adding more units of a variable input to fixed inputs initially increases output, but beyond a point, additional units result in diminishing marginal returns.

The law of diminishing marginal returns describes the decrease in the additional output gained by adding more units of a variable input to fixed inputs.
