Answer : B

In Global Economics for Managers, the profit-maximizing condition for all firms, including monopolies, is when marginal revenue (MR) equals marginal cost (MC), making option B correct.

A monopolist faces a downward-sloping demand curve, meaning that to sell more output, it must lower price. As a result, marginal revenue is less than price. The firm maximizes profit by producing the quantity where the additional revenue from the last unit sold equals the additional cost of producing it.

Option A applies to perfect competition, not monopoly. Option C focuses on revenue rather than profit. Option D has no economic meaning for profit maximization.

Thus, option B is correct.

Answer : D

Average fixed cost is calculated by dividing fixed costs by the quantity of output. Fixed costs are costs that do not change with production volume in the short run, such as rent, certain license fees, salaried administrative expenses, or fixed internet service costs. Option D is correct because the question specifically says ''costs that do not vary with output quantity,'' which identifies fixed costs, and then says those costs are divided by quantity. Total cost equals fixed cost plus variable cost. Marginal cost is the additional cost of producing one more unit. Average variable cost divides variable costs by output. Average fixed cost usually declines as output increases because the same fixed cost is spread across more units. This is why higher production can reduce per-unit fixed cost.

Answer : D

A democracy gives citizens the right to elect representatives who govern on their behalf. Option D is correct because political participation, representative government, accountability, and civil liberties are core features of democratic systems. Democracies generally have institutional checks and balances, rule of law, and mechanisms for peaceful leadership change. These features can reduce arbitrary government action and improve transparency for businesses. Option B describes totalitarianism, where one person or party holds absolute political control. Option C describes a political risk that may occur in some countries but is not a defining feature of democracy. Option A is also incorrect because democracies usually reduce extreme political uncertainty compared with authoritarian systems, although policy changes can still affect firms. The defining feature is citizen representation through elections.

In Global Economics for Managers, purchasing power parity (PPP) is defined as a theory suggesting that the price for identical products sold in different countries must be the same in the absence of trade barriers, making option A correct. PPP is a fundamental concept in international economics used to analyze exchange rates and compare price levels across countries.

The core idea behind PPP is the law of one price, which states that identical goods should sell for the same price when prices are expressed in a common currency, assuming no transportation costs, tariffs, or market frictions. If prices differ, arbitrage opportunities arise, leading market forces to adjust prices or exchange rates until parity is restored.

Option B refers to speculative gains from exchange rate inefficiencies, not PPP. Option C describes herd behavior in financial markets. Option D incorrectly links exchange rates directly to socioeconomic well-being, which is not the theoretical basis of PPP.

Global Economics for Managers distinguishes between absolute PPP, which compares price levels directly, and relative PPP, which focuses on changes in inflation rates and predicts how exchange rates should adjust over time. While PPP may not hold perfectly in the short run due to trade barriers and non-traded goods, it remains a valuable long-run benchmark for evaluating currency misalignment.

For managers, PPP is useful when assessing international cost competitiveness, long-term exchange rate trends, and global pricing strategies. Thus, option A accurately captures the definition and purpose of purchasing power parity.

Answer : A

In Global Economics for Managers, when the multiplier effect exceeds the crowding-out effect, increased government spending causes aggregate demand (AD) to rise by more than the initial increase in spending, making option A correct.

The multiplier effect occurs because government spending generates income, which leads to further consumption. Crowding out occurs when government borrowing raises interest rates and reduces private investment. If the multiplier is stronger, the net effect is an amplified increase in AD.

Thus, option A is correct.
