Maddie Factory has employed 20 workers whose average product is 1000kg’s of wheat. Each worker is given a wage of K2000 whilst the price of each bag of wheat is K20. The factory is considering hiring an additional worker who produces 2000 bags but demands a wage of K3000. Should the additional worker be hired? Show your full working.
there are two scenarios
1. when the wage of the only last worker increased
the worker should be hired if the marginal revenue product of the worker is higher than or equal to the wage.
Marginal revenue product of a worker =marginal product of the worker*price =2000*20=40000
the marginal revenue product is higher than the wage demanded by the worker so it is profitable to hire and the firm should higher the worker.

2. When the wage of all the worker is increased
The marginal profit should be positive to hire the next worker
Total product =average product * number of workers
the total product of 20 workers =1000*20=20000
total revenue =total product * price =20000*20=400000
total labor cost =wage * number of workers =2000*20=40000
profit =400000-40000=360000
=======
after the new workers
total labor cost =21*3000=63000
total product =old total product + marginal product of the employee=20000+2000=22000
total revenue =22000*20=440000
Profit =440000-63000
=377000
Marginal profit =new profit -old profit
=377000-360000
=K17000
the marginal profit is positive so the firm should hire 21st worker to increase its profit by K17000
