Good morning, first of all I want to congratulate @spectrumecons for creating such interesting challenges, since it put us all to think and reason solutions for the different cases proposed but the best thing is that from each context we have an apprenticeship. Here is my entry for challenge # 6 https://steemit.com/sixweekeconomics/@luiyanii/5yrk17-spectrum-economics-challenge-6-cooperation-and-competition

I hope you like it!!

BLESSINGS AND GOOD LUCK FOR ALL!
