## 经济代写|微观经济学代写Microeconomics代考|Welfare Analysis of Partial Equilibria

In the partial-equilibrium framework, once the demand curve and the supply curve of a consumption good are given, the competitive equilibrium of this market, determined by the intersection of demand curve and supply curve, is argued to be Pareto efficient, that is, it is not possible to obtain a Pareto improvement of the utility of the consumers and producers involved by producing a different amount of the consumption good or by allocating it differently.

The argument goes as follows. There are two groups of maximizers: consumers maximize utility on the basis of their given incomes, and producers maximize their income, i.e. profit. Call $x$-good the good exchanged in the market; indicate the quantity produced as $x$, the price as $p$. The given prices of all other goods allow their treatment as a Hicksian composite commodity, whose price can be made equal to 1 by an opportune choice of units and whose quantity therefore can be identified with expenditure $y$ on goods other than $x$, or ‘residual income’ $y$. Then the y-good is actually income or money. It is assumed that consumers have quasi-linear utility functions, linear in residual income; thus consumer h’s utility function is
$$u^h\left(x_h, y_h\right)=z_h\left(x_h\right)+y_h,$$
and when a consumer pays $p$ for one more unit of the $\mathrm{x}$-good she gives up $p$ units of y-good. A producer renounces amounts of y-good as cost to produce amounts of $\mathrm{x}$-good; thus it is as if $x$ were produced by using quantities of $y$ as input. In (internal) equilibrium, all consumers have the same MRS between $x$-good and $\mathrm{y}$-good; the equilibrium marginal utility of income is constant and equal to 1 for each consumer. This means that $p^$, the equilibrium price of the $x$-good, equals the marginal utility of the $x$-good for all consumers active in the market. Producers are interested in maximizing their income, i.e. profit, so they equalize price and marginal cost; hence $M C\left(x^\right)=M U\left(x^\right)$ where $x^$ is equilibrium output.

We have studied the short-period and long-period behaviour of price-taking firms and industries. Before proceeding to the equations of the general equilibrium of the competitive production-and-cxchange cconomy (without capital goods), some considerations on price taking and competition are opportune.

In neoclassical theory, a perfectly competitive equilibrium in a market is an equilibrium between supply and demand in which all agents, consumers as well as firms, are price-takers, that is, treat the equilibrium price as a parameter (a datum they cannot affect) in their optimizations. And a perfectly competitive market is a market where the equilibrium is perfectly competitive. This, as the more careful theorists admit, ${ }^{36}$ does not require consumers and firms to be price-takers at any price-that would be an unsustainable assumption, implying that there would be no one to change a non-equilibrium price. ${ }^{37}$ The realistic traditional argument for a tendency of price towards the equilibrium level is that when demand is not equal to supply, there are either sellers or buyers of the good who are unable to carry through their desired transactions and then have an incentive to propose a slightly lower price (if sellers) or a slightly higher price (if buyers) so as not to remain with unsold wares or unsatisfied demand; then other agents too are compelled to folluw the change (e.g. if a seller asks for a lower price, other sellers are obliged to lower price too, otherwise no one wants to buy from them), and if the stability conditions hold, the price will gravitate towards the equilibrium level. So the gravitation towards equilibrium is due to at least some agents not being price-takers at disequilibrium prices. Is this incompatible with price taking? Price taking for all agents remains possible in equilibrium, but it must be voluntary, that is, there must be no incentive to propose a different price if at the ruling price there is equality between supply and demand.

$$u^h\left(x_h, y_h\right)=z_h\left(x_h\right)+y_h,$$
，当消费者为一单位$\mathrm{x}$ -商品支付$p$时，她放弃了$p$单位y-商品。生产者放弃一定量的y-good作为生产一定量$\mathrm{x}$ -good的成本;因此，就好像$x$是通过使用$y$的数量作为输入而产生的。在(内部)平衡中，所有消费者在$x$ -good和$\mathrm{y}$ -good之间具有相同的MRS;收入的均衡边际效用是常数，对每个消费者都等于1。这意味着$p^$，即$x$商品的均衡价格，等于市场上所有活跃消费者$x$商品的边际效用。生产者感兴趣的是最大化他们的收入，即利润，所以他们平衡价格和边际成本;因此$M C\left(x^\right)=M U\left(x^\right)$，其中$x^$是平衡输出
