The Ramsey problem, or Ramsey pricing, or Ramsey–Boiteux pricing, is a second-best policy problem concerning what prices a public monopoly should charge for the various products it sells in order to maximize social welfare (the sum of producer and consumer surplus) while earning enough revenue to cover its fixed costs.

拉姆齐法则是由剑桥大学经济学教授弗兰克·拉姆齐于1927年在其发表的《对税收理论的贡献》一文中提出的关于制定税率的准则。 即： “为了使税收的超额负担达到最小，税率的制定应能够使得每种商品需求量减少的百分比相等”。 这种使超额负担最小的税叫做拉姆齐税。 [1] 循经济学中常用的 边际分析方法，不难发现，要想使对不同 商品课税 所带来的总体效率损失最小，只有当从不同商品征得的最后一单位税收所引起的效率损失都相等的情况下才行。 也就是说，只要从某种 …

2014年1月3日 · 拉姆齐法则（Ramsey Rule）是指既然无法实现对包括闲暇在内的所有商品征收不产生超额负担的总额税，则效率损失最小的条件是所有商品的边际税收负担相等。

2019年6月1日 · Equation (9) is the Ramsey Rule. It is a necessary condition for optimality in Ramsey Mark III and is unarguably the most famous equation in intertemporal welfare economics. The rule is a formal statement of the requirement of \(\{C^*(t)\}\), that the marginal rate of substitution between consumption at two nearby dates (the left-hand-side of ...

The solution of this optimal tax problem is called the Ramsey rule. See Ramsey (1927). In general terms, the Ramsey rule adopts a complicated formula, as shown

Equation (12) is Ramsey’s basic rule for the optimal system of commodity taxes : if the excise taxes t X and t Y are set so as to raise the required revenue at the minimum possible damage to the taxpayer, then equation (12) must hold. Equation (12) is the exact rule for the \best" commodity tax system : the one which raises

2025年3月20日 · The formula that characterizes optimal commodity taxes in an economy with a single consumer. The Ramsey rule is derived by assuming that the government sets commodity taxes to maximize the utility of a single consumer subject to the chosen taxes generating a required level of tax revenue.

2024年9月8日 · The Ramsey Rule, named after the British economist Frank P. Ramsey, is a principle used in public economics to determine the optimal level of taxation that minimizes the economic distortions and inefficiencies caused by taxes.

Ramsey Equilibrium Allocation rule: x(ˇ) maps policies into allocations (consumption, labor, capital). Price rules: w(ˇ) and r(ˇ) maps policies into prices. A Ramsey equilibrium is an allocation rule x( ), price rules w( ) and r( ) and a policy ˇ such that: 1. ˇ maximizes household utility. 2. households maximize for any ˇ0:

These notes derive “Ramsey's optimal tax formula” that we discussed in lecture. Econ 203 students should understand the logic behind the formula and how the formula might be applied to government
