Define: Competitive Equilibriums

A competitive equilibrium is a state in which the supply and demand for a particular good or service are balanced, resulting in an efficient allocation of resources and no incentive for market participants to deviate from their current behavior.

A competitive equilibrium is determined by the intersection of the supply and demand curves in a market. At this point, the quantity supplied equals the quantity demanded, and the market clears without any excess supply or demand.

In theory, a competitive equilibrium can be achieved in all markets where there is perfect competition and no external factors influencing the market. However, in practice, certain markets may have barriers to entry or other factors that prevent the attainment of a competitive equilibrium.

Price plays a crucial role in a competitive equilibrium as it serves as the mechanism through which supply and demand are balanced. The equilibrium price is the price at which the quantity supplied equals the quantity demanded, ensuring market efficiency.

Yes, government intervention can disrupt a competitive equilibrium. Policies such as price controls, subsidies, or regulations can distort the natural supply and demand dynamics, leading to market imbalances and inefficiencies.

Monopolies are generally not compatible with competitive equilibriums. In a monopoly, a single seller controls the market, limiting competition and potentially leading to higher prices and reduced efficiency compared to a competitive equilibrium.

Externalities, which are costs or benefits that affect parties not directly involved in a transaction, are often not fully accounted for in a competitive equilibrium. This is because the equilibrium only considers the private costs and benefits of market participants, neglecting the external effects.

Market power, which refers to the ability of a firm to influence market conditions, can distort competitive equilibriums. Firms with significant market power can manipulate prices, restrict output, or engage in anti-competitive practices, leading to inefficiencies and a departure from the ideal competitive equilibrium.

Yes, competitive equilibriums can change over time due to various factors such as shifts in supply or demand, changes in market conditions, technological advancements, or shifts in consumer preferences. Market participants must continuously adapt to these changes to maintain a competitive equilibrium.
