Why might some firms voluntarily pay workers a wage above the market equilibrium

b) Paying higher wages can reduce a firm's training costs.

c) Paying higher wages encourages workers to be more productive.

d) Higher wages attract a more competent pool of workers.

Explanation:

Firms will hire more labor when the marginal revenue product of labor is greater than the wage rate, and stop hiring as soon as the two values are equal. The point at which the MRPL equals the prevailing wage rate is the labor market equilibrium.

The idea of the efficiency wage theory is that increasing wages can lead to increased labour productivity because workers feel more motivated to work with higher pay. Paying higher wages encourages workers to be more productive. Higher wages attract a more competent pool of workers. Workers stay with employers longer (instead of seeking out better-paying work with other companies) reducing businesses’ turnover, hiring, and training costs.

by knowing conditionality

explanation:

a recipe serves 8 people, and calls for 5 lbs of apples and 2 cups of flour. you want to prepare it for 24 people. divide 24 by 8 to get 3, and then multiply your ingredients by 3.

so for 24 people, you'll need 15 lbs of apples, and 6 cups of flour.
