A firm produces in a perfectly competitive market and hires labor in a perfectly competitive labor market. The firm hires four workers, the marginal product of the fourth worker is 4, and the wage rate is $40. The firm produces 100 units of the product, which sell for a price of $10. This firm is

This firm is

not maximizing profit and should hire fewer workers to increase profit

Explanation:

Labor=4 workers

Output=100 units

Wage rate=$40

Unit price=$10

Marginal product (MP) of 4th worker=4

Total revenue= Output×price

=100×10

=$1000

Marginal product(MP) is the increase in output as a result of an increase in unit of inputs.

MP= Change in output/change in inputs.

The marginal product of the fourth labour doesn't increase output as required and the fourth labour is paid the same wage rate, in order for the firm to maximize Profit, it is advertised that the firm should reduce labor force.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
