## 经济代写|行为金融学代写Behavioral Finance代考|Too far or not far enough

Disagreement on the kinds of questions we have just discussed means that behavioral economics has no shortage of critics. Some criticize it for not being radical enough. Others criticize it for going too far! As you learn more about behavioral economics it is useful to be aware of this criticism and see how it relates back to the questions above.

Pretty much all criticism stems from the same basic concern, namely that behavioral economics is too much like the standard economic model. As we have seen, behavioral economics takes the standard economic model as its starting point. In practice, this means that behavioral models are almost always the standard economic model plus something new. That ‘something new’ might be a reference point, loss aversion, greater weight on the present than the future, a desire to earn no less than others, and so on. The basic assumptions of the standard economic model are retained, however.

This brings us back to the debate on the methodology of positive economics: will more attention to the decision process result in improved predictive accuracy? I cannot answer that question. I will, however, use this as an opportunity to warn against some of the hyperbole that surrounds behavioral economics – and a lot of hyperbole does surround behavioral economics! Although behavioral economics is revolutionizing economics, it is not as radical a departure from the standard economic model as some would have you believe.

Let us turn now to those who criticize behavioral economics for going too far. If behavioral economics is the standard economic model plus something else, then it is no surprise that we can get a better fit. The danger is one of over-fitting. The basic critique goes something like this. The behavioral economist observes behavior that ‘should not happen’, according to the standard economic model, such as Anna borrowing at a high interest rate on a credit card while simultaneously saving for retirement at a low interest rate. We then come up with something that can ‘explain’ this anomaly, such as an impulsive desire to buy expensive handbags while out shopping. We then congratulate ourselves on a better fit.

## 经济代写|行为金融学代写Behavioral Finance代考|Some background on behavioral economics

We have already seen that behavioral economics involves both theory and experiment. In this section I want to briefly sketch a little more about the methods of behavioral economics and, in particular, give some background on economic experiments. Before doing so I want to make clear that my objective is not to explain how to run experiments, or to perform statistical tests on the experimental data. These warrant books on their own, and there are lots of good books out there (see the further reading at the end of the chapter). All I want to do is explain enough that you will be able to follow the rest of this book. That means, in particular, getting straight some terminology that I am going to use.

Rather than talk abstractly about experiments and theory I thought it would be more interesting to talk through some research that I did (with Federica Alberti and Anna Stepanova) while writing the first edition of the book. This will give me a chance to introduce all the concepts you need at this stage. Other concepts will be introduced as and when needed or relevant in ‘research methods boxes’ that you will find throughout the book.

I will use the term study for a particular piece of research. The objective of our study was to see whether the amount of money people are endowed with in a threshold public good game has any effect on their ability to coordinate. That might not make much sense at this point, but do not worry, because it should make more sense shortly. A study may be part of a more general project. Our ongoing project is to see how people can coordinate better in threshold public good games. The main part of this study involved running experiments, and so I will talk about that first.

## 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。
