Business Economics flashcards for UGC NET Commerce

22 of 61 cards from the Business Economics deck — real questions with worked answers.

1. State the Law of Demand.

   Other things being equal (ceteris paribus), as the price of a good falls its quantity demanded rises, and as price rises quantity demanded falls. There is an inverse relationship between price and quantity demanded.

2. List the main exceptions to the Law of Demand.

   Giffen goods, Veblen (conspicuous/prestige) goods, expectation of future price changes, necessities, and ignorance/quality-judged-by-price situations.

3. Why does the demand curve slope downward (two key reasons)?

   The substitution effect (consumers switch to the now-relatively-cheaper good) and the income effect (a price fall raises real income, increasing purchasing power).

4. Define price elasticity of demand and give its formula.

   It measures the responsiveness of quantity demanded to a change in price. Ed = (% change in quantity demanded) / (% change in price).

5. Name the five degrees of price elasticity of demand.

   Perfectly elastic (Ed = infinity), perfectly inelastic (Ed = 0), unitary elastic (Ed = 1), relatively elastic (Ed > 1), and relatively inelastic (Ed < 1).

6. What is the total outlay (expenditure) method of measuring elasticity?

   If price and total expenditure move in opposite directions, demand is elastic (Ed>1); if they move in the same direction, demand is inelastic (Ed<1); if expenditure stays constant, demand is unitary elastic (Ed=1).

7. State the point elasticity formula along a straight-line demand curve.

   Ed = (dQ/dP) × (P/Q), or geometrically Ed = (lower segment of the demand curve) / (upper segment), measured from the point to the axes.

8. What is the arc elasticity of demand and why is it used?

   It measures elasticity between two points using average price and average quantity: Ed = [ΔQ/((Q1+Q2)/2)] / [ΔP/((P1+P2)/2)]. It avoids the differing results obtained depending on direction of price change.

9. List the main determinants of price elasticity of demand.

   Availability of substitutes, nature of the commodity (necessity vs luxury), proportion of income spent, number of uses, time period, and whether consumption can be postponed.

10. Define income elasticity and cross elasticity of demand.

    Income elasticity = (% change in quantity demanded)/(% change in income). Cross elasticity = (% change in quantity demanded of good X)/(% change in price of good Y); positive for substitutes, negative for complements.

11. State the algebraic relationship between Average Revenue (AR) and Marginal Revenue (MR).

    MR = AR[(e-1)/e], where e is price elasticity of demand. Equivalently AR = MR × [e/(e-1)].

12. Under perfect competition, what is the relationship between AR and MR?

    AR = MR, and both equal price; the firm faces a perfectly elastic (horizontal) demand curve so AR and MR coincide as a horizontal line.

13. Under imperfect competition (downward-sloping demand), how do AR and MR behave?

    AR (the demand curve) slopes downward, and MR lies below AR and falls twice as steeply; MR can become negative while AR remains positive.

14. When AR is a straight downward-sloping line, where does the MR curve lie?

    MR bisects the horizontal distance between the price (Y) axis and the AR curve; it has twice the slope of AR and reaches zero at the midpoint of the AR curve.

15. What is total utility and marginal utility?

    Total utility is the aggregate satisfaction from consuming a given quantity of a good. Marginal utility is the addition to total utility from consuming one more unit; MU = ΔTU/ΔQ.

16. State the Law of Diminishing Marginal Utility.

    As a consumer consumes more units of a good, the marginal utility derived from each successive unit declines, other things remaining constant.

17. State the Law of Equi-Marginal Utility (consumer equilibrium under cardinal utility).

    A consumer maximizes utility when the marginal utility per rupee spent is equal across all goods: MUx/Px = MUy/Py = ... = MU of money.

18. What is the relationship between total utility and marginal utility?

    When MU is positive, TU rises; when MU is zero, TU is maximum; when MU is negative, TU falls. MU is the slope of the TU curve.

19. Define an indifference curve and state its key property.

    An indifference curve shows all combinations of two goods that give the consumer equal satisfaction. The consumer is indifferent among all points on it; a higher curve denotes a higher level of satisfaction.

20. List the main properties of indifference curves.

    They slope downward (negative slope), are convex to the origin, never intersect, and a higher indifference curve represents a higher level of utility.

21. What is the Marginal Rate of Substitution (MRS) and why does it diminish?

    MRS(xy) is the amount of good Y a consumer gives up to gain one more unit of X while staying equally satisfied; MRS = MUx/MUy. It diminishes along the curve due to the diminishing marginal utility, giving the curve its convex shape.

22. State the condition for consumer equilibrium under indifference curve analysis.

    Equilibrium is where the budget line is tangent to the highest attainable indifference curve, i.e. MRS(xy) = Px/Py, and the indifference curve is convex to the origin at that point.
