A monopsonistic market for labor

Vie, 2019-04-19 19:38
When there is a single buyer of labor this type of market is called a monopsonistic labor market. Learn how this changes the analysis of labor markets and why marginal factor cost is higher than the supply of labor in such markets.

Introduction to labor markets

Vie, 2019-04-19 19:38
Just like goods and services, the factors of production are exchanged in markets. This video focuses on such market -- the market for labor. The supply of labor is based on people's willingness to tradeoff labor for leisure. The demand for labor is based on labor's marginal revenue product.

Factor markets worked example

In this video, learn how to apply the analysis of factor markets to a sample problem.

Monopsony labor markets and minimum wages

Vie, 2019-04-19 19:38
We've learned that when a price control is imposed on a market that the result is a decrease in efficiency. But is that always the case? Learn about the counterintuitive case of minimum wages and monopsony labor markets.

Changes in labor supply

Vie, 2019-04-19 19:38
Changes in the supply of labor have an effect on the wage rate. The supply of labor shifts when there are changes in the population, changes in preferences and social norms, and changes in wage rates and opportunities in other markets. Learn how to show the effects of changes in labor supply on wage rates in this video.

Price discrimination for a monopoly

Jue, 2019-04-18 19:21
Price discrimination is charging each consumer their entire willingness to pay. What if a monopolist can charge each buyer their entire willingness to pay? Learn about the effect of perfect price discrimination on output and deadweight loss in this video.

Economic profit for a monopoly

Jue, 2019-04-18 19:21
Learn about how to represent a monopoly market graphically in this video. Topics covered include the profit-maximizing quantity, pricing decisions, and deadweight loss associated with monopolies.

Long term economic profit for monopolistic competition

Jue, 2019-04-18 19:21
Compare and contrast the long run outcomes for monopolistic competition, monopolies, and perfect competition in this video.

Monopolies vs. perfect competition

Jue, 2019-04-18 19:21
Learn about the key differences between the two extremes of competition: monopolies and perfect competition.

Introduction to perfect competition

Mar, 2019-04-16 23:33
Perfect competition is a theoretical market structure in which there are many buyers and sellers, identical products (also called homogeneous products), perfect information, and no barriers to entry.

Free response question (FRQ) on perfect competition

Mar, 2019-04-16 23:33
Walk through the solution to a free response question (FRQ) like the ones you may see on an AP Microeconomics exam. Topics include why price equals marginal revenue (P=MR) for a perfectly competitive firm, how to draw side-by-side market and firm graphs, and how to find several points of interest in the firm graph.

Long-run economic profit for perfectly competitive firms

Mar, 2019-04-16 23:33
A firm in a perfectly competitive market might be able to earn economic profit in the short run, but not in the long run. Learn about the process that brings a firm to normal economic profits in this video.

Long-run supply curve in constant cost perfectly competitive markets

Mar, 2019-04-16 23:33
A constant cost industry is an industry where each firm's costs aren't impacted by the entry or exit of new firms. Learn about the difference between the short run market supply curve and the long run market supply curve for perfectly competitive firms in constant cost industries in this video.

Economic profit for firms in perfectly competitive markets

Mar, 2019-04-16 23:33
An important skill in microeconomics is the ability to find a firm's profit. Learn more about how to use a graph to identify the profit-maximizing quantity for a firm in a perfectly competitive market, and identify the area that represents the firm's profit or loss.

Long run supply when industry costs aren't constant

Mar, 2019-04-16 23:33
In some industries, the number of firms in the market has an impact on the costs that firms face. For example, when firms have to compete with each other over resources, firms' costs increase as more firms enter the market. But in other industries, more firms actually lower costs for firms. Learn about the implications of each of these situations on the long-run supply curve in an industry.
