This article discusses the increase of consumer spending, even though incomes have remained the same. Consumer spending is the largest source of economic activity, and an increase in spending leads to stronger businesses, which leads to more jobs and better wages. This allows the Federal Reserve to scale back on the Economic Stimulus, which offset diminished consumer spending with public spending.

This article describes three major "tragedies" inflicted on the Great Plains of the midwestern United States. The near-extinction of the bison population, the destruction of the grasslands, and the current issue, the massive drilling and oil fracking. It details the repercussions of these tragedies, including a major reduction in its biodiversity.

This article discusses China's developing economy, the major consequences of this growth, and regulations that have been presented to mitigate some of the damage. Their developing economy causes an increasing output of energy required to sustain it, and as consequence, an increase in harmful emissions (a negative externality).

While many assume that a price ceiling on gas would benefit the population, this article takes an opposing view. A price ceiling on gas would cause a shortage, due to the increase in demand of gas at the lower prices, and would cause longer wait times at gas stations. Moreover, it would lead to waste on a larger scale, because the gas is now less valuable.

This article discusses the effects of price ceilings and floors on greenhouse gas emissions and its potential drawbacks with a slower economic growth of the state. This is a good example on considerations of instating an excise tax, because it would reduce emissions, but lower economic growth.

This article describes a relationship between a slight drop in disposable income and a correlating drop in consumer spending in the high streets of Northern Ireland.

Due to the rise in cost for Netflix of obtaining contracts for movies, Netflix has compensated by increasing the price of its DVD mail-service.

Pollution has some major detrimental effects on the climate, so Australia has taken measures to reduce this effect. By instating a pricing mechanism or tax on carbon emissions after a certain threshold has been exceeded, it deters companies from emitting too much carbon, hence reducing the supply of pollutants in the atmosphere.

This article discusses the scarcity of land supply in Chicago and the resulting shift towards home reselling. It explains that, since the scarcity of land has greatly upped the price of constructing new homes, home reselling has consistently and overwhelmingly exceeded new house construction. It also discusses that it was more cost efficient to buy the house, completely demolish it, and rebuild the it on the property than build a new one somewhere else, which provides an example of the sheer effect scarcity has on price.
