Jacob also received an offer to return to his previous job at a salary of $60,000.Jacob sold 20,000 units of his product this year at a price of $24 Step 1 of 2 : Calculate Jacob's total (economic) costs for this year. Enter your answer in the box below, and round to the nearest whole number if necessary.
The following answer is correct: $182,183 Jacob's explicit costs are: $56,284+$17,000+$39,399=$112,683 His implicit costs are: ($190,000×0.05)+$60,000=$69,500 Then, total (economic) costs are: $112,683+$69,500=$182,183 Don't forget to round to the nearest whole number! Step 2 of 2 : Calculate Jacob's economic profit for this year. His total revenue is: Price×Quantity= $24×20,000=$480,000 Now, you can find economic profit. Economic profit=total revenue−total cost $480,000−$182,183=$297,817

A country is about to let refugees in, but current residents are strongly against it. They are afraid that the wages of low-skilled workers will fall if there is an increase in the available workforce. It is estimated that the country can let in 80,000 refugees, but only 65% of them are expected to look for a job. The wage elasticity of labor demand is −0.8. In the country's labor market, there are 624,000 low-skilled workers. Calculate the expected wage drop as a percentage, using the midpoint method. Wage elasticity of labor demand =% change in quantity of labor demanded / % change in wage
