与之相似，Baardwijk和Franses（2010）证明了美国经济

Similarly, Baardwijk and Franses (2010) proved the predictive effect of the "skirt hem index" proposed by the American economist George Taylor on economic trends: they subdivided the length of skirts in an authoritative French fashion magazine, and compared "US The percentage of months in recession each year" serves as an indicator of the quality of the world economy. The results show that the skirt length is short when the economic situation is good, and the skirt length is long when the economy is bad. The curve fits best if the economic indicators are adjusted back for 3 years. <br>Similar indicators include: the "heel index" and the "long hair index" reflecting the economic ups and downs, the "Hamburg Index" reflecting exchange rate changes, the "Poker Index" and "Beer Index" reflecting the unemployment rate, etc. As a sensitive indicator reflecting economic trends, it shows that individual psychological preferences and behavioral decisions can be largely affected by the overall economic operation.

Similarly, Baardwijk and Franses (2010) demonstrate the predictive effect of the hemp index, proposed by George Taylor, the US economist, in predicting economic trends: they break down the length of skirts in a leading French fashion magazine and use "the percentage of us in recession each year" as an indicator of the good or bad of the world economy. The results showed that when the economic situation is good, the length of skirts is short, and when the economy is bad, the length of skirts is long. It would be best to fit the curve after three years of adjusting the economic indicators.<br>Similar indicators include the "shoe index", "long hair index", which reflects exchange rate movements, the "House Index" and the "beer index" that reflect the unemployment rate, which can serve as sensitive indicators of economic trends, indicating that individual mental preferences and behavioral decisions can be largely influenced by overall economic health.

Similarly, baardwijk and Franses (2010) proved the predictive effect of the "skirt index" proposed by American economist George Taylor on the economic trend: they subdivided the length of skirts in a French authoritative fashion magazine, and took "the percentage of months in recession in the United States every year" as an indicator of the world economy. The results show that the skirt length is short when the economy is good, and long when the economy is poor. If the economic indicators are adjusted for 3 years, the curve fitting is the best.<br>Similar indicators include: the "heel index" and "long hair index" reflecting the rise and fall of the economy, the "Hamburg index" reflecting the change of exchange rate, the "Poker index" and "beer index" reflecting the unemployment rate. These indicators can be used as sensitive indicators to reflect the economic trend, indicating that individual psychological preferences and behavior decisions can be greatly affected by the overall economic operation Ring.<br>
