Document Summary

Econ 1116 lecture 7: the costs of production. When the government imposes a binding price floor it causes a surplus. When a tax is imposed on a buyer/consumer the demand curve shifts down. A tax drives a wedge between the price the buyers pay and the price the sellers receive. The questions we are looking to answer are: We assume the firms goal is to always maximize profit. For example, the opportunity cost of owner"s time. The opportunity cost of something is what you give up to get it. Accounting profit = total revenue total explicit costs. Economic profit = total revenue total costs (including both implicit and explicit) i. e. they include the opportunity costs. A production function shows the relationship between quantity of inputs used to produce a good and the quantity of output of the good. At a dollar each you are willing to produce and sell.

Scenario 14-1:

Question 3

B. The kinds of goods for which the free rider problem arises are common resources and public good.

C. Markets for goods for which there is a free-rider problem are inefficient because not enough of the good is produced.

Question 6

B. Efficiency requires that the government provide or fund (subsidize) the provision of all public goods.

C. Efficiency requires that the government provide or fund only the public goods that create more benefits than costs to society.

D. In reality, it is hard to provide public goods efficiently.

Question 7

3 points

Question 10

Which of the following statements about common resources is not true?

A. Due to the free-rider problem, common resources tend to be overused.

B. Because there is rivalry in the consumption of common resources, whenever one person uses a common resource it is imposing a negative externality on others who might also want to use it.

C. There are no private solutions to the management of common resources.
