The prosperity of the economy will increase the value of art, and the economic difficulties will reduce its value. The value of art investment will be high and low from time to time, just like the prices of commodities, stocks and funds. But in the long run, art is a good investment.

人氣和潮流在一幅畫的評估中有重要影響。潮流會改變，而當收藏家們在搜尋某一種特殊的藝術作品類型或某個特定的藝術家，那么其價值就會上升，就如同另外一個藝術家或另外一種藝術作品類型的價值會隨著人氣的下跌而下降。

Popularity and trend play an important role in the evaluation of a painting. The trend will change, and when collectors are searching for a particular type of work of art or a particular artist, its value will rise, just as the value of another artist or another type of work of art will decline with the decline of popularity.

藝術家的名望和作品的質量是關重要的。大師的作品會在一個很高的水平上估價，而那些不那么出名的藝術家的作品的估價會相對比較低，或者說比較適度。而當代藝術家的作品很難確定其價值，其估價通常比其零售更低，因為他們基本上沒有拍賣紀錄。

The reputation of an artist and the quality of his work are crucial. The works of masters will be valued at a high level, while those of less famous artists will be valued at a relatively low or moderate level. It is difficult to determine the value of contemporary artists' works. Their valuation is usually lower than their retail price because they basically have no auction record.
