A city of Hayward has a water reservoir that agricultural user (A) and recreational user (B) have access rights to. Both users A and B want to consume water from the reservoir. The total supply of water there is limited to 18 due to a dry weather this year. User A has inverse demand function: P = 30-Q. User A has marginal cost of pumping water from the reservoir: MC=2. For user B, her inverse demand function is P =20-Q. User B has marginal cost of pumping water (so that she can grow fish in her water garden): MC=2. Efficient allocations are QA- and user B's net benefit is and QB= When the water allocation is efficient, user A's net benefit is . Thus, economic surplus is

Yummy Yummy Popcorn, Inc. sells bags of flavored popcorn in a popular mall. As shop owner and operator, you have observed that weekly popcorn sales are well-described by the demand equation: Q = 1,200 - 800P + 2.0A, where A denotes advertising weekly spending (in dollars). You are currently charging $1.50 per bag of popcorn (for which the marginal cost is $.75) and spending $500 per week on advertising. b) Check whether your current $1.50 price is profit maximizing. If not, determine the store’s optimal quantity and price. c) Should the store consider increasing its advertising spending? Why or why not. Please do fast ASAP fast
Suppose your company seeks to maximize their production. Maximize your company's production function of: 2A + 4B, subject to the following constraints: DM: 1A 1B < = 750 DL: 1A5B < = 1,000 OH: 1A 1B < = 900 Please graph each constraint on the same graph. Put B on the vertical axis. Label the quantity intercept, for each item, on each constraint. Label the point, on each axis, where the maximized function provides the optimal quantity of each item.
Bob's Bee Emporium makes organic honey, which Bob sells at farmers' markets. The value of his Bee Emporium in its current location is $100,000. Unfortunately, Bob's bee's frequently fly to the neighboring property, Daisy's Daycare Center, and sting the small children, some of whom have allergic reaction to the bee stings. Daisy's Daycare Center business is worth $100,000, before the cost of treating any of the children, which the Daycare Center has to pay. The cost of treating the children for the bee stings is $15.000. Relocating the Bee Emporium would reduce its value by $25,000. Relocating the Daycare Center would cost $10,000. The table below shows the value of the businesses under the above conditions. Daisy's Daycare Center Present Location Relocate Bob's Bee Emporium Present Location $85,000 $90.000 $100,000 $100,000 Relocate $100,000 $90.000 S75.000 $75.000 Which situation is economically efficient?

A plant with a marginal abatement function described by MAC = 75-5E is polluting the town's water supply. Emissions are measured in tons per year. a) Government regulators propose that the company pay a tax equal to $30 per ton of emissions. How many tons will the firm abate when faced with this tax, and how much better off will it be compared to if it does no abating. b) Suppose that, instead of the tax, the government offers to pay the firm $30 for each ton of emissions it abates. How many tons will the firm abate, and how much better off will it be compared to if it does no abating? c) If damages caused by the firm's emissions is described by the function MD = 5E, what tax rate would encourage the firm to abate to the socially efficient level of emissions? Compute the private and social compliance cost and the net benefit accruing to society from the socially efficient emissions tax. %3D
Maine has a very old housing stock, with many poorly insulated homes, but poor people often cannot afford to pay for home weatherization. In order to make weatherization more affordable, someone suggests capping insulation prices at 25% less than current values. Assuming that the market is competitive and functions as modeled by mainstream economic theory, which of the following is most likely to be true? select best answer from following ():The lower price for insulation will shift the demand curve for insulation. ():This policy will increase consumer surplus by more than it reduces producer surplus. ():This policy would benefit the poor, since they would be the most likely to buy the cheaper insulation ():With a lower price for insulation, firms will provide less, and fewer people will insulate their homes. ():With insulation more affordable, more people will insulate their homes.

Suppose the inverse demand curve on ore is given by P = X - 0.47 Q. Ore can be either mined or obtained through a recycling program. The marginal cost of mining is MC1 = 8 q1. The marginal cost of obtaining ore through recycling is MC2 = 91 + 2 q2. What should be a maximum value of X so that recycling is NOT cost-effective?
Please drag and drop the markers 1 through 5 below to denote the appropriate position on the diagram that answers the question. The correct position for each marker is worth 4 points. 1) Show with marker 1 on the horizontal axis the equilibrium level of output in period 1 that would occur if marginal costs equal zero and if there was no allocation for period 2. 2) Show with marker 2 on the horizontal axis the equilibrium level of output in period 2 that would occur if marginal costs equal zero and if there was no allocation in period 1. 3) Show with marker 3 on the horizontal axis the equilibrium level of output in each period if the marginal cost is zero output is allocated optimally between the two periods. 4) Show with marker 4 on the vertical axis the marginal user cost. 5) Show with marker 5 on the vertical axis the maximum (choke) price in period one.

Suppose that pig farming in a region is a perfectly compet- itive industry. However, one negative consequence of this activity is that it creates water pollution that adversely affects the health of the residents in the nearby communities that rely on the water sources that are contaminated by the pig farms. The market supply curve for pigs (or hogs) is given by H^S = 6p where H^S is the quantity of hogs supplied to the market by farmers in this region. The market demand for hogs is given by H^P = 300 – 4p. The government estimates that the additional medical costs (M) imposed on the nearby communities is given by M = 5H, where H is the quantity of hogs produced and sold in the market. Q: In the absence of clearly defined property rights over water use or con- ventions or some form of government intervention, derive the market equilibrium for hogs and the DWL resulting from the additional medical costs associated with hog production. Please show the formula, thank you.
Metropolitan Utilities District currently charges residents in Omaha $1.23 per cubic feet of water use for each home's first 900 cubic feet of water used, $1.73 per cubic feet of water use for each home's usage rate between 900 and 3,000 cubic feet, and $2.22 per cubic feet of water use for anything over 3,000 cubic feet of use. The pricing structure is an example of: over-use and inefficient pricing. too few water permits being traded on the local water market. block pricing. conservation pricing.
Assume the relationship between the growth of a fish population and the population size can be represented as g= 8S – 0.2S2, where g is the growth in tons and S is the size of the population (in thousands of tons) a. Given a price of $100 a ton of fish, what is the marginal benefit of smaller population sizes?
