Jim Hamilton, one of my professors, has a great blog which analyzes current events from a macroeconomic point of view (Econbrowser.com). For instance, in the post “Just how implausible is a gasoline tax,” Hamilton reviews a NYT article which states that while 85% of Americans oppose a gas tax, 59% would support a gas tax if it reduced energy consumption and reduced global warming. Which of these statements truly represents American’s true preferences?
