Pester power is a child's ability to affect their parents' marketing decisions, often through the use of nagging, or pestering.
“兒童消費(fèi)力”指的是兒童影響其父母消費(fèi)決策的能力，通常通過嘮叨和糾纏不休達(dá)到讓父母購物的目的。

The phrase is used to describe the negative connotations of children's influence in their parents buying habits.
這種說法用來描述兒童對(duì)其父母的購物習(xí)慣帶來的負(fù)面效應(yīng)。

Pester Power is commonly used by marketing companies to target the 4–6 years old category as they have limited disposable income of their own, and consequently do not have the means to buy goods themselves.
營銷公司常用“兒童消費(fèi)力”來描述4到6歲的兒童的這種行為。他們自己沒有什么錢，因而無法自己買東西。

The growth of the issue of Pester Power is directly related to the rise of child advertising.
“兒童消費(fèi)力”問題愈發(fā)突出與兒童廣告的增加直接相關(guān)。

A key concern of pester power is its effect on childhood obesity. As the products which are promoted to children are pre-sugared cereals, soft drinks, savoury snacks, confectionery and fast food, which in turn are some of the most calorie-dense of all food articles.
對(duì)“兒童消費(fèi)力”最主要的擔(dān)憂是其對(duì)兒童肥胖的影響。商家針對(duì)兒童的廣告商品卡路里含量非常高，比如含糖谷物食品、軟飲料、美味的零食、糖果糕點(diǎn)和快餐。

EXAMPLE:

Several times a day the boy mentioned the expensive video game to his mom, hoping that pester power could convince her to buy it for him.
這個(gè)男孩一天好幾次向他的媽媽說起這款昂貴的電子游戲，希望用他的糾纏能力逼媽媽為他購買。
