Market Types — Set 4

Correct Answer: C. One seller and one buyer

Bilateral monopoly is a market situation with one monopolist (single seller) and one monopsonist (single buyer). This often leads to intense negotiation or bargaining to determine the final price and quantity. Labor unions negotiating with a single large employer is a common example.

Correct Answer: A. Market Period

The market period is so short that the supply of the commodity is fixed and cannot be changed. In this period, price is mainly determined by the changes in demand. It is most applicable to highly perishable goods like fish or flowers.

Correct Answer: C. Oligopoly

An oligopoly is defined by the dominance of a small number of sellers catering to a huge number of consumers. These sellers are often large corporations with significant market power. Because there are so few, each seller's moves are carefully watched by the others.

Correct Answer: B. Bullion Market

The bullion market is a specialized market where high-purity gold and silver are traded. Trading is done in the form of bars, ingots, or coins. It serves both as a source for industry and a destination for investors.

Correct Answer: A. Patent Rights

Patent rights are considered the most significant legal barrier to entry in a monopoly. A patent grants the inventor exclusive rights to produce, sell, or use a product or process for a fixed period (usually 20 years). This prevents competitors from entering the market legally. While control over raw materials, government licensing, and economies of scale are also important barriers, patents specifically represent a legal instrument of protection that directly creates monopoly conditions by prohibiting imitation.

Correct Answer: A. Downward sloping

A monopolist faces a downward-sloping demand curve, meaning they can sell more only by reducing the price. Since they are the only seller, the firm's demand curve is the same as the market demand curve. This relationship dictates how they choose their profit-maximizing output.

Correct Answer: C. Oligopoly

The correct answer is 'Oligopoly'. Oligopolistic firms often avoid competing on price to prevent mutually destructive price wars. Instead, they compete through quality, service, and heavy advertising. This focus on non-price factors is a key survival strategy in this market type.

Correct Answer: D. All Market Structures

Average Revenue is defined as Total Revenue divided by Quantity, which mathematically always equals the Price per unit. This identity holds true regardless of the market type or the number of sellers. Therefore, the AR curve is also the demand curve for the firm.

Correct Answer: B. Profit Maximization

Economists generally assume that the goal of every firm is to maximize its total profits. This occurs when the firm produces at a level where Marginal Revenue equals Marginal Cost. While other goals may exist, profit maximization is the central assumption in microeconomic models.

Correct Answer: B. Monopolistic Competition

Monopolistic Competition is characterised by excess capacity in the long run. Firms produce at a point to the left of the minimum Average Total Cost, which means they are not operating at peak efficiency. This happens because product differentiation allows firms to charge a price above marginal cost but competition drives economic profits to zero. Perfect Competition achieves productive efficiency. This excess capacity is also sometimes called the "cost of variety" since consumers pay for product differentiation.
