In his most recent New York Times Magazine column, Adam Davidson writes about how he and his Planet Money colleagues surveyed the shopping indicator scene to see what Americans' shopping patterns might tell us about the state of the economy.  From lipstick (once a strong indicator, now not so much) to Champagne sales ("consistently accurate"), there is no shortage of goods that are extolled as strong indicators.  But in the end, the big takeaway is that consumers seem to remain consumers, and have yet to transition into savers.  Davidson:

Of all the indicators we looked at, one of the most consistently accurate was Champagne sales. The amount of French Champagne that Americans consume has predicted — with nearly 90 percent accuracy — the average American income one year later. Apparently, when we pop a Champagne cork, we know that good times are ahead (see chart). Champagne sales hurtled upward twice in recent history — at the peak of the Internet bubble in 1999 and during the heyday of the housing bubble in 2007. These were both followed by slowdowns as fewer people found reason to celebrate.

There are so many indicators to choose from that you could glean just about anything regarding our economic future. In fact, the most telling indicator appears to be the sheer number of indicators themselves. Americans now have so many seductive things they can buy that there are ample consumer options no matter what we feel. Partly as a result, savings — known in economics as deferred consumption — have fallen steadily for more than 30 years, from a high of nearly 12 percent of income. It kissed zero before a tiny uptick in the past couple years.

The decline of the savings rate is particularly troubling because it is consistent through busts and booms. During the fast growth of the late 1990s and mid-2000s, and the dark times that followed, people have been choosing to spend more and save less than ever before. Paradoxically, this happened just as pensions have been disappearing and life spans have been increasing. It suggests that Americans are so caught up in every short-term enthusiasm or agony that they haven't thought enough about long-term fiscal health.
