The
Concept Introduction:
Opportunity Cost: It is the cost of next best alternative that is foregone in order to pursue one course of action. It refers to the benefits which are given up in the process of obtaining some other benefits.
Expert Solution & Answer
Explanation of Solution
- In the above case,the time spent in search of tools could have been used by workers to finish their assigned tasks.
- The B Company used assembly line method of production in which products were moved from one assembly line to other at a steady rate. This eliminated the need of workers to wander and saved time to work.
- The amount of work left unfinished due to time spent in search of tools is the opportunity cost of roaming around and searching for tools.

2. A firm’s production function is given by:Q = 10KLThe unit capital and labour costs are 2 and 1 pounds respectively. The firm is contracted to produce2000 units.(a) Write out the optimisation problem of the firm. (b) Express this problem using a Lagrangian function. (c) Find values of K and L which fulfil the contract with minimal cost to the firm. (d) Calculate the total cost to the firm.
3. Consider the following estimated regression equation, estimated using a sample of firms, where RDis total firm spending on research and development in USD ($), Revenue is total firm revenuein USD ($), and W ages is the firms’ total spending on wages in USD ($) (standard errors inparentheses):RDd = 1000(600)+ 0.5(0.1)Revenue + 1.5(0.5)W ages,(a) Interpret the coefficients on each of the explanatory variables. (b) Which of the three coefficients are statistically significant at the 5% level of significance? Howdo you know? A researcher runs a two-sided statistical test of the null hypothesis that both the coefficients onthe explanatory variables above are jointly equal to 0.25 (mathematically, that β1 = β2 = 0.25),and reports a p-value of 0.045.(c) What does this p-value mean for the outcome of the test? (d) What would an appropriate two-sided alternative hypothesis look like?
