There are some cookies that sell for $1. The baker says she wants to to buy one for $2. Everyone now thinks the cookies are worth $2 and will pay $2 for the cookies. The main art world sales trick that really got me was the fact that galleries oftentimes buy the work of their own artists. I guess a lot of businesses invest back into themselves of course but in the case of the art world oftentimes buying a work can falsely inflate the value of the artist. Damian Hirst and his diamond encrusted human skull are rumored to have executed this scheme with his gallery, investors, and even the artist himself buying the skull merely to safe (diamond encrusted) face...if no one else bought the piece the price of his work would lessen in value and the Hirst stock would plummet so everyone wins in this slight of hand! I do have to wonder if this kind of game had anything to do with the artist's recent split with his representation though?
O you want the first cookie? Well...you can have cookie number three! Because "other people" obviously wanted cookie one & two! Editioned art work also greatly suffers from the ghost buyer too, with gallerists often owning an edition (or one, or two, or ten) of a piece (whether it be film or prints or photographs etc.) in order to make the piece seem more in demand than it actually is. The gallerist pays half price (if they pay anything at all) and then is able to price the remaining editions higher and also create a false demand. I find this practice pretty wrong. Especially since once the fake demand is set the gallerist can potentially sell his personal holdings for even more money.

Someone else really wants that cookie, I can put you on the wait list for it and let you know when it, or another like it, is available? This game is one that is sometimes practiced on the up-and-up but has also been known to be used as another trick of the trade. Gallerists will sometimes tell a buyer that a piece is on hold (meaning someone wants to buy it that is more important than you) even when it is not in order to create a false demand and also pressure the buyer when contacted about the piece's "sudden" availability. The other practice, that was dominant in the 90s art market heyday, but I think has calmed down a bit thanks to this little thing called the recession/depression, is the wait list, a system in which someone agrees to buy whatever the next available work by an artist is. This is a weird one, completely dismissing the attachment to the content and treating the work strictly as a money chip of sorts...it isn't wrong but it draws the work from being about art to being solely about money...a terrifying byproduct of the supply and demand nature of most markets but a particularly dreary fact when applied to culture.
You can give the cookie to charity and then declare it as a tax write off...It's no wonder that the last time I attended Miami Basel the major sponsor was USB, and it is also no coincidence that this art fair occurs right on the cusp of the end of the fiscal year! Money can be hidden and moved easily through the asset of artwork. Especially tax deductible money. People buying art as a donation to an institution makes it a tax deductible gift and money is saved in the end. I do know that a lot of places profit from this kind of transaction but buying up art as a means to hide money or get rid of large sums quickly to avoid paying taxes on it is another sad truth of how people treat cultural value today...

In trying to think of the best way to avoid the pitfalls of art market bullshit the only advice or comment I have is: buy directly from the artist. This practice supports the work itself, it cuts out the middle man (the gallerist who gets 50% of the sale- which is crazy- and adds to the price inflation so the artist can make money/cover production costs after the split, and in most cases is just adding to the already large wallet of many a rich-kid gallerist), and it ensures that the value of the art is based on something other merely profit. Now I am going to eat some cookies. And try to appreciate art as art and not the smoke & mirrors commodity it has become!
