Imperfect Competition

Pure competition

Oligopoly

Perfect competition

Monopoly

Producer surplus decreases due to administrative costs associated with implementing perfect price discrimination strategies.

Producer surplus increases as they capture what used to be consumer surplus by charging each consumer their maximum willingness to pay.

Producer surplus remains unchanged because total revenue remains constant though it's distributed differently among consumers.

Producer surplus might either increase or decrease depending on how effectively the firm segments its market and extracts surpluses from high-demand customers only.

It remains unchanged as the monopolist still sets prices above marginal cost.

It decreases slightly but persists due to consumer surplus extraction.

It is eliminated as the firm produces where price equals marginal cost.

It increases since consumers are charged different prices based on their willingness to pay.

This could create an artificial floor on wages, increasing employment levels above the monopsony outcome yet potentially inducing labor shortages in specific sectors.

Subsidies are likely to generate minimal changes given that monopsonists already possess marked control over wage setting, limiting the effectiveness of such interventions.

Subsidies can eventually lead to greater monopolistic tendencies within the labor market as companies expand and consolidate further exercising control over wages.

This may result in exacerbated income inequality as workers receive disparate subsidy amounts based on sector employment.

Subsidies cause small firms to enter the market more easily, which disrupts current monopolies or oligopolies by increasing competition significantly.

Market competition intensifies as subsidized firms expand production capabilities leading to better quality products at lower prices.

Subsidies may entrench dominant firms' positions further, reducing incentives for innovation and potentially leading to higher prices once competition has been weakened.

Long-term market dynamics remain stable since subsidies are neutralized by regulatory measures aimed at curbing anti-competitive behaviors.

Consumer surplus remains unchanged as the price ceiling does not affect differentiation of products.

Consumer surplus will decrease due to increased competition among firms.

Consumer surplus may increase, benefiting from lower prices for some consumers.

Consumer surplus will decline because of reduced availability of goods due to black markets.

Social welfare could increase as resources are allocated more efficiently and deadweight loss is eliminated, although income redistribution effects may raise concerns about fairness.

Social welfare remains unaffected as the change simply alters the distribution between consumer and producer surpluses without impacting overall efficiency.

This transition leads directly to an increase in social welfare because it promotes competition by removing monopoly power from individual sellers.

The shift toward perfect price discrimination results in decreased social welfare due to a reduction of consumer surplus and an increase in producer surplus.
