Concept Introduction:
The positive or negative consequences faced by an unrelated third party or parties due to the performance or undertaking of an economic activity are known as externalities. The cost of economic activity incurred by a third party or parties is known as negative externalities.

5) Suppose:
i) the price of gasoline is $2 per gallon
ii) current consumption is 400 (million) gallons per day
iii) the elasticity of demand is -0.8
iv) retail provision of gasoline may be approximated as a constant cost industry
v) there is an external cost of $0.5 per gallon of gas.
Calculate deadweight loss associated with the externality. Draw a figure to illustrate.
3. The effect of negative externalities on the optimal quantity of consumption
Consider the market for electric cars. Suppose that a electric car manufacturing facility dumps sludge into a nearby river, creating a negative
externality for those living downstream from the facility. Producing additional electric cars imposes a constant per-unit external cost of $600. The
following graph shows the demand (private value) curve and the supply (private cost) curve for electric cars.
Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $600 per unit.

- (Negative Externalities) Suppose you wish to reduce a negative externality by imposing a tax on the activity that creates that externality. When the amount of the externality produced per unit of output increases as output increases, the correct tax can be determined by using a demand-supply diagram; show this. Assume that the marginal private cost curve slopes upward.

Efficiency in the presence of externalities Roses confer many external benefits on society: the beauty they add to a room or garden, the wonderful aroma they give off, and so on. Therefore, the market equilibrium quantity of roses is not equal to the socially optimal quantity. The following graph shows the demand for roses (their private value), the supply of roses (the private cost of producing them), and the social value of roses (the private value and external benefits). Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socially optimal quantity.arrow_forward

- 1) People who live on the edge of small lakes sometimes have break walls constructed on their property by the shore. A break wall is typically a vertical column of wood or concrete that prevents high water levels from covering part of the owner's property, reducing the size of the beach, and/or eroding the yard. However, several communities have restricted property owners from building break walls. What is one reason for that? Hint: Think about potential externalities of building a break wall.
