Suppose there are 100 farmers each with 10 acres that overlie a common groundwater aquifer. They all have identical farmland that is more productive if wells are used to pump the groundwater for irrigation. They all face a marginal cost of $10 per well. The average productivity (in $ of crop output) of the wells of the common aquifer is given by AP = 100 – W where W is the number of wells drilled into the aquifer. 1. Now assume one farmer buys all the land – how many wells will be drilled and what will be the rent generated. A. 45; 2025 B. 90; 2025 C. 60; 1000 D. 90; 0 E. 45; 0 F. None of the above
Suppose that a demand function is given by q = D(p) = 20(7 - ((p) with superscript (2)/square root of ((p) with superscript (3) + 1))) , where q is the demand for a product and p is the price per unit in dollars. Find the rate of change in the demand for the product per unit change in price. a.(dq/dp) = (-20(p) with superscript (4) + 80p/(((p) with superscript (3) + 1)) with superscript (1/2)) b.(dq/dp) = (10(p) with superscript (4) - 40p/ (((p) with superscript (3) + 1)) with superscript (3/2) ) c.(dq/dp) = (-10(p) with superscript (4) - 40p/ (((p) with superscript (3) + 1)) with superscript (1/2) ) d.(dq/dp) = (-10(p) with superscript (4) - 40p/ (((p) with superscript (3) + 1)) with superscript (3/2) )
Assume that the demand curve is P = f(Q) = 60 − 0.2Q and the supply curveis P=g(Q) = 30 + 0.3Q. Find the equilibrium price and quantity and also compute consumer and producer surplus by applying integral.
The biological relationship between the growth for the fish population and the size of the fish population is g = 15S(1S/5) where g is the growth of the fish population and S is the size of the population. The size of the harvest is a function of the amount of human effort expended b = 3ES where E is the level of effort. Market price of fish per unit is $100 and a constant marginal cost of effort is $50. If we rewrite the sustainable harvest/catch level equation in terms of effort level, E, then we have b s = E E-
