## 经济代写|Microeconomics代考微观经济学代写|Choice of Technique

Now let us assume that, for at least one commodity, there are several alternative methods to produce it, each one represented by different technical coefficients. I keep assuming that all capital goods are circulating capital goods, that land is a free good, that labour is homogeneous, and that there is no joint production.

A technique (also called production system by some authors) is a set of methods of production, one for each commodity. It is represented by a couple $\left(\mathbf{A}, \mathbf{a}_{\mathbf{L}}\right)$ where $\mathbf{A}$ is square. Two techniques are different if they differ even in only one method. Two methods for the production of the same commodity differ if they differ even in only one coefficient.

Note that different techniques need not include the same number of commodities. Suppose for example that in the given economy tomatoes is one of the basic commodities produced, and call $\alpha$ the dominant method with which they are produced and $(\alpha)$ the technique of which it is part; then a new method $\beta$ to produce tomatoes is discovered, which uses a specific new fertilizer only needed for that purpose. Technique $(\beta)$ will then differ from technique $(\alpha)$ not only in the specific method that produces tomatoes, but also because it includes an industry not present in technique $(\alpha)$, that produces the special fertilizer.

We now study how competition selects the technique among the several available ones, and how this choice can depend on income distribution.

The starting point is the following: assume a given technique and given real wage rate, and assume competition has imposed a uniform rate of profit and the associated prices of production. Suppose new methods to produce a commodity become available. On the basis of the ruling prices, entrepreneurs will calculate the price at which each alternative method allows to sell the commodity if it is to yield the ruling rate of profit and will prefer the method associated with the lowest of these supply prices: if this lowest supply price is lower than the ruling price, the method can yield extra profits, by adopting it in place of the ruling one the firm can sell the product at a price slightly below the ruling price, subtract custom from its competitors and nevertheless earn a higher rate of profit. If it is the method until then dominant that guarantees the lowest supply price, the new methods are not adopted. We will call cost minimizing (at the given prices and distributive variables $\mathrm{w}, \mathrm{r}$ ) the method that yields the lowest supply price for the given commodity. If it is a new method, its generalized adoption changes the technique, then competition will cause relative product prices to tend toward the new values, and it can happen that at these new relative prices in the same industry or in other industries other methods until then not adopted come out to be the cost-minimizing ones. So the technique can change again. We must find out the final situation, if it can be determined, toward which this process of choice of technique tends.

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
