In most cases, if a i rm increases its service capacity by 10 percent, it would expect waiting times to be reduced by what percentage? Assume customer arrivals and service times are random.

Consider a market with the following supply and demand.  (It may help to draw a graph for these questions.) P            5            6            7            8            9            10            11            12           13           14 QS        200       300        400       500        600        700         800          900        1000       1100 QD       800       750        700       650        600        550         500          450         400         350 If there is an external cost of $3, what is the efficient quantity? 500 (already answer) If there is an external benefit of $3, what is the efficient quantity? 700 (already answer) For the remaining questions assume that there is a $3 external COST. If the government wants to get the efficient quantity with a per/unit tax, how much should the tax be? 3 (already answer) Now imagine that they use tradable allowances.  If they cap the quantity at 400 what would the value of these allowance be in the market?  (Assume the…

You are the principal economist at a firm that produces some output y based on the following function: y = f(x1, x2) = x ³ x ² 1. Calculate the marginal product (MP) of both inputs at some arbitrary input bundle (x₁, x₂). Interpret the sign of both. 2. Using your answer in the previous part, calculate OMPT₂/0x₁. Interpret what this means. 3. Calculate the technical rate of substitution between ₁ and x2, i.e., MP/MP₂. 4. Does this production function exhibit increasing, decreasing, or constant returns to scale? Show. 1 5. Lay out a brief, realistic example of x₁, x2, y that fits the dynamics that you calculated.

If sales volume decreases and all other factors remain constant, then the Multiple Choice   margin of safety will increase.   break-even point will decrease.   contribution margin ratio will increase.   net operating income will decrease
