We can estimate the emissions caused in one year from automobile use. What can you do to offset these emissions? Buy a green tag. These voluntary purchases are akin to carbon offsets traded in Europe. For a small fee, individuals can purchase carbon offsets for their cars or SUVs, or companies can use them as a way to purchase wind power for their stores. Organizations selling the green tag (both for-profit and not-for-profit) provide a decal; most of the fee collected is provided to alternative energy producers as a subsidy, which then can lower their prices to the market to encourage use. Is this a public good being sold privately? Why would individuals or businesses buy a tag when they can free-ride?Question

The Presidio, previously a military base in San Francisco, is now a national park. It sits in the middle of San Francisco on some of the most valuable real estate in the United States. Congress, when it created the park, required that it rehabilitate the aging buildings and be self-sufficient within a decade or so, or the land would be sold off to developers. The park appears to be well on its way to self-sufficiency by leasing the land to private firms—Lucas Films has built a large digital animation studio, and other firms have undertaken similar projects. These projects all must maintain the general character of the park and generate rent that will cover the park’s expenses in the future. Would this privatization approach work with most of America’s other national parks? Why or why not?Question

Nobel Prize–winner Simon Kuznets once suggested that poor nations tend to pollute more as they grow—until they reach a certain level of income per capita—after which they pollute less. Does this observation by Kuznets seem reasonable? Why or why not?

One’s home (whether a house or an apartment) is typically thought of as one’s castle. But not so in the condominiums with homeowners associations (HOAs) in Jefferson County, Colorado. In an older four-unit condo, the HOA voted 3–1 to adopt a no-smoking rule (inside the individual condos) after smokers bought one of the units and smoke permeated the walls of the structure. In 2006, a district judge ruled that the HOA’s adoption of no-smoking rules was a reasonable restriction on ownership rights, stating that the rules were designed to prevent the odor of cigarettes from penetrating the walls of neighboring condos.
Considering that there are a small number of people involved (three nonsmoking units, one smoking), you would think that transaction costs would be minimal. Why do you think the homeowners could not work out an agreement (à la Coase) and ended up in court? According to the Coase theorem, would it have made any difference if the judge had ruled against the HOA?
