Transcript

[SQUEAKING] [RUSTLING] [CLICKING] JONATHAN GRUBER: All right, let's get started today with our lecture on factor markets. So when we talked about producer theory, we talked about input prices, that firms had prices for their wages and their capital. And we just sort of posed those as given. I just sort of gave you values for the wage and the renter... Read More

Key Insights

• ☠️ The wage rate and productivity are important determinants in the labor demand and supply.
• 🔬 The labor demand and supply are influenced by factors like market competition and the elasticity of labor supply.
• 🖐️ The income effect and substitution effect play a significant role in labor supply decisions.

Questions & Answers

Q: Where do wages and prices for labor and capital come from?

Wages and prices for labor and capital are determined in factor markets based on supply and demand dynamics. Factors such as productivity, market competition, and demand for goods and services play a role in shaping these prices.

Q: How does a perfectly competitive factor market affect the labor demand?

In a perfectly competitive factor market, firms hire workers based on the marginal benefit of labor, which is determined by the marginal product of labor and the marginal revenue of the goods produced. The firms hire workers until the marginal benefit equals the wage rate.

Q: Does the elasticity of labor supply differ between men and women?

Yes, historically, women have had a higher elasticity of labor supply compared to men. This is because women often have more flexibility in choosing whether to work or not, whereas men tend to have a fixed work schedule.

Q: How has the elasticity of female labor supply changed over time?

The elasticity of female labor supply has decreased over the years as it has become more common and socially accepted for women to work. The income effect has also played a role, with families becoming more dependent on dual incomes.
