如果你想知道自己是不是大款，只需看看每天自己使用的科技便一清二楚。

芝加哥大學的經濟學家最近與全美經濟研究所發表了一篇論文，研究了過去幾十年當中最顯著的財富衡量指標。論文發現，在2016年（論文分析所涉及的最后一年），是否擁有蘋果手機可作為一項指標，而且準確率達到了69.1%。

蘋果的iPad也可以作為一項評判指標，其準確率為66.9%。緊隨其后的是成為Verizon Wireless客戶（61%），擁有安卓手機（59.5%）。

使用Kikkoman醬油是概率排名第五的評判指標（59%）。

除了產品之外，經濟學家們發現（Business Insider此前曾報道過這些發現），在美國旅行時持有護照、車中裝有藍牙設備是高收入指標榜單上靠前的指標。此外，車中擁有加熱座椅或使用洗碗機清洗劑也是有錢概率較高的指標。

這些發現揭示了這些年來財富指標所發生的明顯變化。例如，在1992年，如果用得起Grey Poupon第戎芥茉醬或手頭有現金，那么有62.2%的可能性是富人。2004年，如果你是美國乳業巨頭藍多湖公司的定期用戶，那么你肯定是個富人。同年，如果你購買了一輛新車，你是富人的可能性高達73.6%。

研究中的另一個與科技相關的發現在于：如果在1992年擁有一臺Sylvania電視機，有57.4%的概率可以肯定你是一名富人。（財富中文網）

If you really want to know if you’re rich, look no further than the technology you’re using each day.

Economists at the University of Chicago recently published a paper (PDF) with the National Bureau of Economic Research that examined the best indicators of wealth over the last few decades. And it found that in 2016, the last year it analyzed, there was a 69.1% chance of accurately guessing that a person was wealthy if he or she owned an iPhone.

Apple’s iPad was a predictor in 66.9% of cases. It was followed by being a Verizon Wireless customer at 61% and owning an Android handset at 59.5%.

Using Kikkoman soy sauce was the fifth-most-likely indicator at 59%.

Aside from products, the economists, whose findings were earlier reported on by Business Insider, found that if traveling in the U.S., owning a passport, and having Bluetooth in your car were also high on the list of high-income indicators. Having a heated seat in your car or using dishwasher detergent were also good wealth indicators.

The findings show a distinct difference in wealth indicators over the years. For instance, in 1992, there was a 62.2% chance that if you were using Grey Poupon dijon mustard, you had some cash. In 2004, that was true if you wee a Land O’ Lakes Regular user. That same year, if you bought a new vehicle, there was a 73.6% chance you were wealthy.

One other tech-related takeaway from the study: Owning a Sylvania TV in 1992 meant there was a 57.4% chance of accurately identifying you as wealthy.
