The cost of desalinating seawater using conventional technology in the Persian Gulf is high (around 0.1£ per cubic meter) and requires extensive amounts of oil. Some time ago scientists suggested that it could well prove both practically feasible and less expensive to tow icebergs from the Antarctic, a distance of about 9600 km. Although some of the ice would undoubtedly melt in transit, it was thought that a significant proportion of the iceberg would remain intact upon arrival in the Gulf. Bear in mind that since water expands upon freezing, 1 cubic meter of ice produces only 0.85 cubic meter of water A study was carried out to evaluate the practical problems associated with such a proposal and to quantify the factors that were likely to influence the economics of such a venture. One factor was the difference in rental costs and capacities of towing vessels (summarized in Table 1). Note that each vessel has a maximum iceberg it can tow (measured in cubic meters). It was found that the melting rate of the iceberg depends on both the towing speed and the distance from the South Pole (see Table 2). The data in this table represents the rate at which a hypothetical spherical iceberg shrinks in radius over a day at the given distance from the Pole and at the given towing speed. Finally, fuel cost was found to depend on the towing speed and the (current) size of the iceberg (see Table 3). Determine whether it is economically feasible to produce water from icebergs in the Persian Gulf, and if it is,
Determine the best means to do so. the questions were given in this case are :
1-what do we know ?
2-what can we assume?
3-what would results look like ?
4-what information can be brought to bear?
5-what can we ask the client?
6-problem statement: in what ways could ?
7-decisions a number of draft commercial?
8-ways to simplify?
9-modules ?
Terry has a demand function for oysters given by the equation q=.02m-2p, where m is income and p is price. Terry's income is $8,000 and he initially has to pay a price of $40 per oyster. Assume the price of oysters rises to $80. Calculate the substit..
The initial price of a cup of tea is $1, and at that price, 400 cups are demanded. If the price falls to $0.90, the quantity demanded will increase to 500. Calculate price elasticity of demand for tea using the midpoint formula. Calculate the (point)..
When the competition is intense and the environment is changing rapidly, it is especially important to
Explain how natural monopolies cause market failure? How is the deadweight loss associated with this form of market failure measured? What is a typical form of government intervention to correct it? How effective is this type of intervention?
Proposals to raise the minimum wage rate are often opposed with the argument that such a move would not only cause an increase in the unemployment rate but would also hurt the very people it is intended to help. Is there any validity to that argument..
Draw the demand and supply curves for the market for pediatric visits. Label the curves and the axes with titles, and calculate and label the equilibrium price and quantity.
Suppose Nation A can produce 2 million pounds of sugar per week OR 1 million pounds of rice in a week and Nation B can produce 10 million pounds of sugar per week OR 3 million pounds of rice in a week. If this is a two-good, two nation model,
The city government is losing millions of dollars on the mass transit system (buses and subways). The government proposes to increase the fare of a ticket by 20% to raise revenue and has asked your advice. You know that the price elasticity of demand..
In the Solow growth model, a higher savings rate is a good way to get higher GDP and higher GDP growth. The Solow growth model tells us that a flood of immigrants will, in the long run, raise interest rates and reduce wages. In world in which absolut..
Compared with perfect competition, quantity produced in monopolistic competition is inefficient as price is higher than marginal cost (i.e. allocative inefficiency). Why do some economists argue that even if price is higher than marginal cost, it doe..
