Household ProductionGardening, cooking, ironing,
childcare, car repair, painting—many people do these things “in-house.”
Household production makes sense if the opportunity cost is less than market price.

ExternalitiesPrivate production and
consumption can impose costs on parties “outside
the market.” Some costs of production or consumption
are thus externalized.
Examples:
Air, water, noise pollution; cigarette smoke; acid rain; mosquitoes.
![Page 11: Economic decision makers](https://reader035.fdocuments.net/reader035/viewer/2022081422/56816663550346895dd9f3ba/html5/thumbnails/11.jpg)
In a world where externalities occur, market forces cannot
always be relied upon to allocate resources efficiently. This creates a legitimate reason for government
regulation.
Examples of government policy aimed at externalities:
•Effluent taxes•Pollution “permits”•Subsidized vaccinations•Auto emission standards•Open burning ordinances•Smoke free workplaces

Public GoodsA good that, once produced, is available for all to consume regardless of who pays and who doesn’t; such a good is nonrival and nonexclusive.
•Public goods are subject to a free-rider problem.•Examples include lighthouses, flood control, and national defense.

Tax Principles and Tax Incidence
• Ability-to-pay tax principle• Benefits-received tax principle• Tax incidence– Proportional taxation: Flat tax (as % of income)– Progressive taxation: marginal tax rate
– Top 1% of tax filers – paid 36.9% of taxes– Top 10% of tax filers – paid 68.2% of taxes– Bottom 50% of tax fillers – paid 3% of taxes
– Regressive taxation

By making the tax structure “progressive,” governments can make the after-tax distribution
of income more equitable (or even).

Assume a 7.13 percent excise tax on groceries, gasoline, cigarettes, and liquor
Moral of the story: Low income families tend to spend a greater proportion of their income on items subject to excise taxes. Hence excise taxes tend to be regressive.

The rest of the world

The Global Economy

Exchange rates

expressed in terms of another currency.
![Page 28: Economic decision makers](https://reader035.fdocuments.net/reader035/viewer/2022081422/56816663550346895dd9f3ba/html5/thumbnails/28.jpg)
If the dollar price of the British pound is:
1.45 dollars = 1 pound
Then the pound price of the dollar is given by the reciprocal of the dollar-pound exchange rate. That is:
Pounds per dollar = pounds69.045.11
