Assessing Perfect Competition Market Structure and Efficiency

The video explores the market structure of perfect competition, focusing on its efficiency in resource allocation. It discusses productive and allocative efficiency, highlighting that perfectly competitive markets achieve these efficiencies in the long run. However, it notes that perfect competition is a theoretical construct and not fully applicable in real-world markets. The video also examines the impact of externalities on allocative efficiency and the limitations of perfect competition in fostering innovation and long-term economic growth due to normal profit constraints.

What is the role of firms in a perfectly competitive market?

• They set their own prices.

• They are price takers.

• They are price makers.

• They have a monopoly.

In perfect competition, when are firms considered productively efficient?

• When they produce at the lowest point of the AC curve.

• When they produce at the highest point of the AC curve.

• When they produce at any point on the AC curve.

• When they produce at the midpoint of the AC curve.

What condition must be met for allocative efficiency in perfect competition?

• Price equals fixed cost.

• Price equals total cost.

• Price equals marginal cost.

• Price equals average cost.

Why is perfect competition considered a theoretical construct?

• Because it is the only market structure.

• Because it is commonly found in real markets.

• Because it is used as a benchmark for real markets.

• Because it does not involve any competition.

How do externalities affect allocative efficiency in perfect competition?

• They ensure that private and social costs are equal.

• They cause private and social costs to differ.

• They have no impact on allocative efficiency.

• They make private benefits exceed social benefits.

What is a potential downside of perfect competition regarding long-term growth?

• It leads to excessive innovation.

• It results in high levels of research and development.

• It may limit innovation due to normal profits.

• It encourages monopolistic practices.

What is a key takeaway from the evaluation of perfect competition?

• Perfect competition is not useful as a theoretical benchmark.

• Perfect competition is both productively and allocatively efficient.

• Perfect competition guarantees high profits for firms.

• Perfect competition always leads to high economic growth.
