Again, you are not getting the point. If "it does not matter if the content was manually reworded/spun or by using a spinning tool."?, why did you even mention it in your first replies? Be careful about what you write. Again, this is a summary study guide taken from the book I use with my students as the main book for Economics Engineering at Universidad Centroccidental Lisandro Alvarado, Barquisimeto, with contributions on my side that I have already explained in my previous replies (rewording of some content to make it more clear, solution of proposed problems that are not solved in the book, etc.). It is logical that a summary guide of this nature has re-worded parts so that my students can better understand the concepts. If I wanted to write a completely original and innovative scientific paper, I would do it in the American Economic Review, not in Hive. I am the author of the blog I published in Hive, but as I said before, it is a study guide, with the book I mentioned included there as a reference and complement. I have not published this article anywhere else if that is what you want to know. My Twitter? It is Hive account@luishbc317. My Instagram? It is Hive account@vision4s; but again, I have not published this summary guide there. Regards, bot!
