Hi Everyone,
Welcome to the ‘Buying and Selling Game’ Contest 33 and final results post for the Buying and Selling Game Series. A new economics series will begin in 2023. Next month’s post will explain this new series of contests.
This post contains a video of the ‘Buying and Selling Game’ Excel Model. The model generates the selling prices for the goods described in the contest post. For contest 33, the participants had a choice of six types of donuts, which were available on 5 different planets, this contest goes outer space sometimes. Watch the video to find out what our participants did and who won the contest.
For the benefit of those who have not entered this contest, here is a brief explanation of how the game works.
Participants are required to buy goods with an allocated amount of money. They are given a choice of 6 goods and all of these goods are available in any of the 5 towns, cities, islands or planets in the game. The buying prices of all goods are provided in the question.
The participants are then required to sell all of their goods on a future date. The selling prices for all goods in all towns, cities, islands or planets are not provided. Instead, the question provides a triangle distribution for the selling price of each good in each town, city, island or planet. For the triangle distribution, the minimum, maximum, and mode values are provided.
The participant who has the most money after selling all his or her goods is the winner.
Responses to the contest are made in the comments section of the post. If more than one participant makes the highest profit, the participant who entered (commented) first will win. The account with the winning entry will receive 30 Hive and the first 12 entries will be given upvotes. The most profitable buying and selling price combination is also calculated. If the winner adopts this strategy, he or she will receive an additional 10 Hive. If nobody makes a profit (i.e. zero or negative), the prize will be rolled over to the next contest.
The format of the required entry is explained in detail in the contest itself.
For a more detailed explanation, you can access the contest post using the following link.
Table 1 contains the selling prices generated by the ‘Buying and Selling’ Game model for each type of donut on each planet.
Table 2 contains the responses and the profit made by each participant.
Congratulations to 
On Paczki, she bought 1234 jam filled donuts for $1.62 each. She paid a total of $1,999.08.
On Bear Claw, she sold the 1234 jam filled donuts for $1.944 each. She received a total revenue of $2398.90. Therefore, she made a profit of approximately $400 (2398.90 – 1999.08).
I would also like to thank 
To achieve the best chance of winning the game (i.e. earning the highest profit). Participants need to make the best use of the information they are given. The participant should buy from the place that sells the good at the lowest price and sell at the place that will offer the highest price.
To inform the decision further, participants should also consider the mean and median prices for each good in each place. The mean and median for a triangle distribution can be calculated using the following formulae.
Mean = (Minimum + Maximum + Mode)/3
Median when Mode ≥ (maximum – minimum)/2 (i.e. mode closer to maximum)
Minimum + (((maximum – minimum) × (mode – minimum))/2)0.5
Median when Mode ≤ (maximum – minimum)/2 (i.e. mode closer to minimum)
Maximum - (((maximum – minimum) × (maximum – mode))/2)0.5
