Hi Everyone,
Welcome to my third instalment of my collection of Hive works. I have previously authored two posts containing my work relating to economics. This third instalment focuses on contests. I have run several contests since being on Hive. I initially began with puzzle contests and then I moved onto memes and then contests more closely related to economics. When I create more contests, I will include the links in this post. My other ‘Collection of Works’ posts will also be updated frequently.
The updated Parts 1 and 2 of the collection of works can be accessed using the following links.
As with the previous collections of work, I have divided my subject matter into categories. The categories included in Part 3 are as follows:
In April and May in 2018, I ran my ‘Spectrum Economics Six Week Challenge’. The series brought the economics and the contest aspects of my account together. The series was intended to help people think about economics and how it applies to and influences their lives. The challenges varied from analysis and problem solving to articulating and explaining how economics can be applied to everyday life.
In July and August of 2021, I brought back the challenge series. I extended it from 6 weeks to 7 weeks by including an additional challenge. This time round participants only needed to respond in the comments section. I intend to run this challenge every year. Below are the links to all the challenges and results posts for both challenge series.

I had created a number of different contests prior to the buying and selling game. These included puzzles, memes, and the six week economics challenge series. I wanted to run contests that could be more closely linked to economics. I managed to achieve that with the six week challenge series but I could not run such a series indefinitely. The third challenge in the series was a buying and selling challenge, which proved quite popular. This challenge could also be modified into a simpler contest.
I built an Excel-based model that would generate the prices of goods for the contest. The participants were required to buy goods at a given price at one of five locations. They were then required to sell these goods at another location but were not given the prices for these locations. Instead, they were given the mode, minimum, and maximum prices for a triangle distribution. The participant who made the highest profit would win. This game incorporated economics and a bit of luck. The results would always be unbiased as the Excel-based model generated the prices. This game became known as the Buying and Selling Game.
In 2021, the Buying and Selling Game was updated to include a business version. The business version required the participant to buy or produce up to three types of goods (e.g. three types of t-shirts). The participant could buy or produce as many of these goods possible within the given budget. The participant would then be required to set the selling price for these goods. The Excel-based model would determine the demand for each good as well as how many goods each participant could sell at the prices that were set. The participant with the highest profit would win.
The Buying and Selling Game is held monthly and alternates between the original version and the business version.

In 2023, I started a new economics series to replace the previous ‘Buying and Selling Game’ series. This series is held monthly. It is held in 10 of the 12 months. The remaining two months are reserved for the annual Economics Challenge Series. Each contest in the series will be unique. Some of the contests are from previous challenge series and others will be completely new. The first contest in the series was the 2022 Christmas contest.

At the beginning of 2024, I published my fiction ebook, Sapien Loop. This might seem like a massive departure from my regular economics writing, but the story falls very much in line with my economics content. The only difference is that it is expressed as fiction and in the context of an alien planet and civilisations. To find out more about the book, check out my 
I am using the Sapien Loop quizzes as a method of attracting more people to read the book and, hopefully, buy it. I run one quiz a month; there are normally seven multiple-choice questions. The participant who answers the most questions correctly wins.

I have always loved solving puzzles. I have now taken that to a new level by creating new puzzles and puzzle contests. I normally create 4 puzzles per a contest. The first person to solve all the puzzles wins. The puzzles are generally quite difficult with just a few people each week finding all the answers. Puzzles are not directly related to economics but puzzles require analytical ability, which is critical to economics. Think of solving puzzles as an indirect way of improving your prerequisite skills for economics.

Memes and meme contests, well this series is really just for a bit of fun. I have many photographs from my adventures in life and some of them are quite humorous and can be used to create some really funny memes. I also have a thing for memes and how they can add value to an explanation. I often create memes for my economic posts to emphasize a particular point. In short, memes are great fun and can tell a story in an instant.

I have launched my first Udemy course ‘Economics is for Everyone’. The course focuses on how economics affects everyday people, the decisions they make and how they interact with the world around them. The course contains 24 video lectures (about 4 hours of viewing), 64 multiple-choice questions (3 at the end of most lectures), 32 downloadable resources (presentation slides, additional notes and links to relevant Hive posts), and 2 scenario questions. The course is currently free-of-charge. Click the link above to access the course.
