actually the reason for higher prices is more likely due to INFLATION.. a dollar 15 years ago is not worth as much as dollar is today..
You would be foolish to think that inflation is the reason that prices for Jordans have gone up so dramatically over the last 15 years. While it may play a minor role, it is not the main reason.
Allow me to offer a little perspective for you...
SB Dunks lows were $65 in 2003...GR's are now $85. That's an increase of 31% in 11 years.
Nike Air Raid were $90 in 2003...The "Peace" colorway retrod this past weekend for $125. That's an increase of about 39% in 11 years.
Jordan III (white cement) retro'd in 2003 for $110. They will sell for approx $200 in 2015 (if they retro). That's an increase of 82% in 12 years
Jordan I (royal) retro'd in 2001 for $80. They retro'd again in 2013 for $140. That's an increase of 75% in 12 years
Jordan XII (several) retro'd in 2003 for $135. They will sell for approx $200 in 2015 (if they retro). That's an increase of a little over 50% in 12 years.
Aside from the fact that price increases are significantly more for Jordan retros than non-Jordan retros, the price increase rate is all over the place. The inflation rate is the inflation rate...it doesn't vary from item to item. These price increases aren't based on inflation rates...They're based on what Nike can sell their products for on the market. They increase their prices by large amounts because they can still sell their products at these increased prices.
And just to be clear, not everything has gone up in price. Someone already mentioned cell phones, but home electronics as an industry is constantly declining in price and becoming more affordable. CD's used to cost $18 back in the day...They certainly don't cost that much now...Neither do televisions or computers.
NTers have a habit of throwing around the term "inflation" like it's a high-intellect, complicated finance term. It's not. It's also not the answer to "why do Jordans cost more now than they did before".
