Theory of Production and Costs

This set of flashcards covers key concepts in production theory, the conditions for equilibrium in both competitive and monopolistic markets, and the effects of costs and taxes on firm behavior.

What is the Lagrangian multiplier used for in production theory?

It is used to find the maximum output given constraints on resources.

What is the primary condition for the equilibrium of a firm in production?

The marginal productivities of factors must equal the ratio of their prices.

What does the slope of the marginal product curve indicate?

The marginal product curve must have a negative slope for equilibrium.

What happens when the costs of production increase in a pure competition model?

The output decreases, and the price increases in the short run.

In monopoly, how does the demand curve typically behave?

The demand curve is negatively sloping.

What condition must be satisfied for a monopolist to maximize profit?

Marginal revenue must equal marginal cost (MR = MC) and the slope of MC must be steeper than that of MR.

What is the relationship between price and marginal revenue in a monopoly?

Price is greater than marginal revenue (P > MR) because the monopolist must lower price to sell additional output.

How does a lump-sum tax affect a monopolist's equilibrium?

It reduces excess profits but does not alter output or price in the short or long run.

What distinguishes constant-cost, increasing-cost, and decreasing-cost industries?

Constant-cost industries have stable factor prices as output expands; increasing-cost industries see rising factor prices; decreasing-cost industries have falling factor prices with increased output.

What is the effect of a specific tax on the monopolist's price compared to pure competition?

The price increase might be smaller than, equal to, or larger than the specific tax, depending on market conditions.
