This assignment is intended to help you learn to do the following:

• Define what “market failure” means.
• Explain why the market underproduces “public goods.”
• Explain how externalities distort market outcomes.
• Describe how market power prevents optimal outcomes.
• Define what “government failure” is.

Review the section of your text that covers market failure and government failure. In addition, find and read two recent articles on this topic. Write a 500-750 word (approximately 2 to 3 page) paper that addresses these questions:

• What are some examples of market failure and government failure?
• What challenges do economies face in light of optimal allocation and public goods?

Support your conclusions with the findings from the articles and the textbook as well as any other sources you would like to use. Format the paper according to General APA Guidelines. You do not need to include an abstract but you must include a title page and a references page. These pages are not included in your word/page count.

This rubric assignment includes:

1. A complete definition of the target and accessible population from which the sample would be This definition should thoroughly describe the size of this population and relevant characteristics (e.g., age, ability, socioeconomic status, etc.). This is based on your PROPOSED study.
2. A description of how you will determine the sample size. Include a summary statement that indicates the sample size that will be selected and justification for this Be sure to identify your anticipated response rate and cite your sources!
3. An explanation of the sampling techniques by which you would select the sample and form it into groups (if appropriate). This technique should be described in detail, including justification of the technique For example, if using “stratified sampling”, do not just say that stratified sampling will be used; indicate on what basis (i.e. characteristic) the population will be stratified and how group members (and how many) will be selected. Please also identify any possible sources of sampling bias.

I will give you further information after selection.

In short: First, use unsupervised learning techniques to determine Kmeans and hierarchal clustering. Next, use random forest classification to predict cluster number and calculate accuracy. Last, write Kmeans clustering from scratch using Python [No packages can be used for this part]. Compare results.

Long version:

First, use dataset1 (csv) with unsupervised learning techniques. Use Kmeans to determine the # of clusters. Tabulate the # of clusters from 1 – 40 and total within-cluster variance. Plot the scree plot. Using hierarchal clustering, calculate the pairwise distance. Create various dendrograms using complete and average linkage. Cut dendogram into groups of 5-7. Which is the most appropriate # of groups?

Next, do the same exercise above except this time we use random forest classification.

Last, using dataset2 (csv), write a function (without using Kmeans related packages) that calculates the within cluster variance, aggregates the data by the cluster number, and plots “total within cluster vs. number of cluster”. Add the cluster number to the last column of dataset, predict the cluster number using logistic regression and calculate the accuracy of your model.

Briefly compare results from each method.
