O. Chanel et al., PRICES AND RETURNS ON PAINTINGS - AN EXERCISE ON HOW TO PRICE THE PRICELESS, Geneva papers on risk and insurance. Theory, 19(1), 1994, pp. 7-21
Art is priceless, but paintings, and other objects, have been sold on
markets since the time of the Roman Empire. In this paper, we describe
a method for constructing a price index for paintings and compare thi
s index to the indices of various financial markets. In particular, we
discuss whether the price of art is related to financial markets, whe
ther the art market is weakly efficient, and whether it is more or les
s risky than financial markets.
