导数与微分: 可用于计算边际量, 例如: 在生产厂商使自己利润最大化的时候遵循的就是“边际相等的原则”, 即边际收益=边际成本, 而此边际量就要运用导数和微分来求。

 

Derivative and Differential coefficient: they can be used to calculate the marginal items. For example, manufacturers will follow the principle of “marginal equality” to maximize the profit, namely, marginal revenue = marginal cost, while the marginal item will be computed by derivative and differential coefficient.

 

积分学: 在福利经济学分析生产者剩余和消费者剩余的时候可以通过供给曲线和需求曲线运用积分学求出两种剩余, 进而进行比较, 使社会效用最大化北京翻译公司。

 

Integral: when analyzing producer surplus and consumer surplus in welfare economics, integral can be used to compute two types of surpluses through the supply curve and demand curve, and then make comparison and maximize the social utility.

 

Linear planning: it’s the issue for computing the minimum or maximum value of linear function under the linear constraint. For example, when determining the optimized action of consumers and producers in the market, linear planning may be used to determine the way to maximize or minimize the variable under certain restrictions.
