Limitations
The notion of (constant) risk aversion has come under criticism from behavioral economics. According to Matthew Rabin of UC Berkeley, a consumer who,
from any initial wealth level turns down gambles where he loses $100 or gains $110, each with 50% probability will turn down 50-50 bets of losing $1,000 or gaining any sum of money.
It is noteworthy that Rabin's article went on to criticize the whole field of expected utility and not just constant relative risk aversion. This has led to some confusion in the field. One solution to the problem observed by Rabin is that proposed by prospect theory and cumulative prospect theory, where outcomes are considered relative to a reference point (usually the status quo), rather than to consider only the final wealth.

Famous quotes containing the word limitations:
“To note an artist’s limitations is but to define his talent. A reporter can write equally well about everything that is presented to his view, but a creative writer can do his best only with what lies within the range and character of his deepest sympathies.”
—Willa Cather (1876–1947)
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
