For each of following, explain whether you think the situation is efficient or not. If it is not efficient, why not? What actions would make it efficient?
Electricity is included in the rent at your dorm. Some residents in your dorm leave lights, computers, and appliances on when they are not in their rooms.
Although they cost the same amount to prepare, the cafeteria in your dorm consistently provides too many dishes that dinners don’t like, such as tofu casserole, and too few dishes that dinners do like such as roast turkey with dressing.
The enrollment for a particular course exceeds the spaces available. Some student who need to take this course to complete their major are unable to get a space even though others who are taking it as an elective do get a space.
Concept Introduction:

- If GDP goes up by 1% and the investment component of GDPgoes up by more than 1%, how is the investment share ofGDP changing in absolute terms?▶ In economics, what else is expressed as relative percentagechanges?arrow_forwardCEO Salary and Firm SalesWe can estimate a constant elasticity model relating CEO salary to firm sales. The data set is the same one used in Example 2.3, except we now relate salary to sales. Let sales be annual firm sales, measured in millions of dollars. A constant elasticity model is[2.45]ßßlog (salary) = ß0 + ß0log (sales) + u,where ß1 is the elasticity of salary with respect to sales. This model falls under the simple regression model by defining the dependent variable to be y = log(salary) and the independent variable to be x = log1sales2. Estimating this equation by OLS gives[2.46]log (salary)^=4.822 + 0.257 (sales) n = 209, R2 = 0.211.The coefficient of log(sales) is the estimated elasticity of salary with respect to sales. It implies that a 1% increase in firm sales increases CEO salary by about 0.257%—the usual interpretation of an elasticity.arrow_forwardSolvearrow_forward

The graph also shows Oiram-46's marginal revenue curve and its average total cost curve. On the following graph, use the orange point (square symbol) to indicate the profit-maximizing quantity. Use the blue point (circle symbol) to indicate the profit-maximizing price. Use the purple point (diamond symbol) to indicate the average total cost. Use the tan rectangle (dash symbol) to show Oiram-46's total revenue and the grey rectangle (star symbol) to show its total cost.
