While CV and EV are exact measures of the change in welfare, the change in CS is an approximate measure that is only valid for specialized preferences. At old prices, “Equivalent …

2023年4月10日 · 根据图示，补偿性变化（cv）、等价性变化（ev）和消费者剩余的变化量（ ∆cs ）之间的关系为 |EV|≤|∆CS|≤|CV| 这里我们使用绝对值表示三者的大小。

CV, or compensating variation, is the adjustment in income that returns the consumer to the original utility after an economic change has occurred. In the case of a positive economic …

In economics, compensating variation (CV) is a measure of utility change introduced by John Hicks (1939). 'Compensating variation' refers to the amount of additional money an agent …

二、 CV、EV和ΔCS三者之间的关系：拟线性 效用函数的情况 • 结论： 在拟线性效用函数情况下有CV=EV， 进一步，必有 CV = ∆CS = EV。 1、定义一: 利用图示 • 补偿变化CV： Key: 价格 …

Computes exact EV and CV (and DWL) rather than approximation Use Shephard’s lemma and Roy’s identity to retrieve Hicksian demand and expenditure function. Steps: 1. Using Roy’s …

Comparison of CS, EV CV • Empirically, we are able to estimate CS, but not EV or CV. • How close an approximation is CS to EV or CV? – Depends on magnitude of the income effect – …
