1An economy produces only two goods, Good X and Good Y, operating on its Production Possibility Frontier (PPF). Moving from combination A (X = 0, Y = 100) to combination B (X = 20, Y = 60), what is the opportunity cost of producing one additional unit of Good X?

A.2 units of Good Y

B.0.5 units of Good Y

C.40 units of Good Y

D.20 units of Good Y

Explanation: Opportunity cost of Good X in terms of Good Y is calculated as OC_X = |ΔY| / ΔX. Here, ΔY = 60 - 100 = -40 (giving up 40 units of Y) and ΔX = 20 - 0 = 20 (gaining 20 units of X). Therefore, OC_X = 40 / 20 = 2 units of Good Y per unit of Good X.

2An economy exhibits a concave Production Possibility Frontier (PPF) reflecting the law of increasing opportunity cost. The combinations are A (X = 0, Y = 150), B (X = 10, Y = 140), C (X = 20, Y = 120), D (X = 30, Y = 90), and E (X = 40, Y = 50). What is the opportunity cost of Good X when expanding production from X = 20 to X = 30?

A.1 unit of Good Y

B.2 units of Good Y

C.3 units of Good Y

D.30 units of Good Y

Explanation: Moving from C (20, 120) to D (30, 90), the change in Good X is ΔX = 30 - 20 = 10 units, and the sacrifice of Good Y is |ΔY| = |90 - 120| = 30 units. The opportunity cost per unit of X is OC_X = |ΔY| / ΔX = 30 / 10 = 3 units of Good Y.

3An economy produces two goods, X and Y, with a linear Production Possibility Frontier given by 2X + Y = 200. If the economy fully employs all its productive resources and produces 60 units of Good X, what is the maximum attainable production of Good Y?

A.60 units

B.80 units

C.100 units

D.140 units

Explanation: Full employment on the PPF requires satisfying the equation 2X + Y = 200. Substituting X = 60 yields: 2(60) + Y = 200 => 120 + Y = 200 => Y = 200 - 120 = 80 units.

4A technological breakthrough improves productivity exclusively in the production of Good X, while the technology for Good Y remains unchanged. How does this shift the Production Possibility Frontier (PPF)?

A.The PPF shifts outward entirely parallel to the original curve.

B.The horizontal intercept for Good X rotates outward to the right, while the vertical intercept for Good Y remains fixed.

C.The vertical intercept for Good Y rotates upward, while the horizontal intercept for Good X remains fixed.

D.The PPF shifts inward toward the origin due to factor substitution.

Explanation: Because technological improvement affects only the production of Good X, the economy can produce more of Good X with the same resources, shifting the X-axis intercept outward. If all resources were devoted to Good Y, maximum output of Y is unchanged, so the Y-axis intercept remains fixed.

5The linear demand equation for a consumer good is Q_D = 120 - 4P. What is the point price elasticity of demand (E_D) when the price is P = 15?

A.-0.50

B.-1.00

C.-2.00

D.-4.00

Explanation: At P = 15, Q_D = 120 - 4(15) = 120 - 60 = 60 units. Point price elasticity of demand is defined as E_D = (dQ_D/dP) * (P/Q_D) = (ΔQ/ΔP) * (P/Q). Here, ΔQ/ΔP = -4. Substituting P = 15 and Q = 60 gives: E_D = -4 * (15 / 60) = -4 * 0.25 = -1.00 (unitary elasticity).

6When the price of a good rises from P_1 = 10 euros to P_2 = 30 euros, the quantity demanded decreases from Q_1 = 100 units to Q_2 = 60 units. What is the arc price elasticity of demand (E_D_arc)?

A.-0.50

B.-1.00

C.-1.50

D.-0.25

Explanation: The arc elasticity formula is E_D_arc = (ΔQ / ΔP) * ((P_1 + P_2) / (Q_1 + Q_2)). Here, ΔQ = 60 - 100 = -40 and ΔP = 30 - 10 = 20. Thus, ΔQ / ΔP = -40 / 20 = -2. The midpoint factor is (10 + 30) / (100 + 60) = 40 / 160 = 0.25. Therefore, E_D_arc = -2 * 0.25 = -0.50.

7A firm faces a price elasticity of demand of |E_D| = 0.6 (inelastic demand). If the firm increases its selling price by 20%, what happens to its Total Revenue (TR)?

A.Total revenue increases because the percentage increase in price is greater than the percentage decrease in quantity.

B.Total revenue decreases because higher prices always reduce total market purchases.

C.Total revenue remains constant because elasticity is strictly non-zero.

D.Total revenue falls by exactly 12%.

Explanation: When demand is price inelastic (|E_D| < 1), a price change causes a proportionally smaller opposite change in quantity demanded (%ΔQ = -|E_D| * %ΔP = -0.6 * 20% = -12%). Since TR = P * Q, the 20% increase in P outweighs the 12% drop in Q (new TR = 1.20P * 0.88Q = 1.056 TR, a 5.6% increase). Thus, Total Revenue increases.

8A market consists of two identical consumers, each with an individual demand curve given by q_i = 50 - 2P (for P <= 25). What is the aggregate market demand equation Q_D?

A.Q_D = 100 - 4P (for P <= 25)

B.Q_D = 50 - 4P (for P <= 12.5)

C.Q_D = 100 - 2P (for P <= 50)

D.Q_D = 25 - P (for P <= 25)

Explanation: Market demand is obtained by horizontal summation of individual quantities at each price: Q_D = q_1 + q_2 = (50 - 2P) + (50 - 2P) = 100 - 4P, valid for P <= 25 (at P > 25, quantity demanded is zero).

9The market supply function for a manufactured product is Q_S = -20 + 5P (for P >= 4). What is the price elasticity of supply (E_S) at a price of P = 10?

A.0.60

B.1.25

C.1.67

D.5.00

Explanation: At P = 10, Q_S = -20 + 5(10) = 30 units. The derivative of supply with respect to price is dQ_S/dP = 5. Price elasticity of supply is E_S = (dQ_S/dP) * (P/Q_S) = 5 * (10 / 30) = 50 / 30 = 5/3 ≈ 1.67. Since E_S > 1, supply is price elastic.

10A competitive market has demand Q_D = 500 - 10P and supply Q_S = 100 + 10P. What are the market equilibrium price (P_0) and equilibrium quantity (Q_0)?

A.P_0 = 20 euros, Q_0 = 300 units

B.P_0 = 25 euros, Q_0 = 250 units

C.P_0 = 15 euros, Q_0 = 350 units

D.P_0 = 30 euros, Q_0 = 200 units

Explanation: At market equilibrium, quantity demanded equals quantity supplied: Q_D = Q_S => 500 - 10P = 100 + 10P. Solving for P: 400 = 20P => P_0 = 20 euros. Substituting P_0 into either equation gives Q_0 = 500 - 10(20) = 300 units (and Q_S = 100 + 10(20) = 300 units).
