Economic bubble



An economic bubble is "trade in high volumes at prices that are considerably at variance with intrinsic values". It could also be described as a trade in products or assets with inflated values. While some economists deny that bubbles occur, the cause of bubbles remains a challenge to those who are convinced that asset prices often deviate strongly from intrinsic values. While many explanations have been suggested, it has been recently shown that bubbles appear even without uncertainty, speculation, or bounded rationality. It has also been suggested that bubbles might ultimately be caused by processes of price coordination or emerging social norms.

Because it is often difficult to observe intrinsic values in real-life markets, bubbles are often conclusively identified only in retrospect, when a sudden drop in prices appears. Such a drop is known as a crash or a bubble burst. Both the boom and the burst phases of the bubble are examples of a positive feedback mechanism, in contrast to the negative feedback mechanism that determines the equilibrium price under normal market circumstances. Prices in an economic bubble can fluctuate erratically, and become impossible to predict from supply and demand alone.

Azara (plant)


Azara is a genus of ten species of flowering plants in the family Salicaceae, native to temperate to subtropical regions of South America. Azara was formerly classed in the family Flacourtiaceae.

They are evergreen shrubs and small trees growing to 1-8 m tall. The leaves are alternate, or in some species they appear paired, are simple 1-9 cm long and 0.5-5 cm broad. The opposite-leaved appearance of some species is unusual in that one stipule is enlarged giving the appearance of opposite ["paired"] leaves.

The flowers are small, yellow or greenish, strongly fragrant, with a 4-5-lobed calyx and no petals but conspicuous long, often brightly colored, stamens; flowering is in spring. The fruit is a red to black berry 3-10 mm diameter.

Several species are cultivated as ornamental plants in gardens.

Girl in the Bubble

Bubbles (voiced by Tara Strong in the series and Kath Soucie in the What-a-Cartoon! shorts) is a fictional character in animated television series The Powerpuff Girls. She is portrayed as having short blonde hair in two pigtails, light blue eyes, and dresses in light blue. The ending theme refers to her as "the joy and the laughter", meaning that she is the cutest of the group (despite being the same age) and is defined by a sweet, cheery, and gentile demeanor.

Bubbles does, however, have a tendency to be overemotional, despite the fact of her having a habit to be ditzy, naive and sensitive leading to her sometimes being regarded as the group's best link, by friends and foes alike. However, she can become very independent and aggressive, let alone extremely mad when pushed. Out of all the Powerpuff Girls she is the most feared by Mojo Jojo after having single-handedly taken him down in a fit of rage in the episode Bubblevicious. Her special superpowers are the Sonic Scream, understanding various foreign languages, and communicating with animals. Her best friend is Octi, a stuffed octopus. Her personality is sugar and her signature color is light blue.
