Supply & Demand - A Commerce Journey - Ep8
How Hypixel Skyblock Teaches Supply & Demand Like a Pro
Q1: Why Does Ice Cream cost more in the summers?
Scarcity
Needs & Wants
Needs can be defined as the resources and products essential for our survival; clothes, shelter, food, etc.
Supply & Demand
- The law of Supply: This part of the law states that, generally, the quantity of a good or service that producers are willing to supply increases as the price of that good or service increases. This is because higher prices offer greater potential profits for producers, incentivizing them to produce and sell more
- The law of Demand: This part of the law states that, generally, the quantity of a good or service that consumers are willing to purchase decreases as the price of that good or service increases. This is because consumers have a limited budget and will tend to reduce their consumption of a good or service as its price rises.
The Invisible Hand: Drawing the curves that control the market
The above is a representation of Price vs Supply, you can see price very gradually going up (bullish outlook) and the supply follows slowly. People tend to wait for higher prices to sell to maximize profit.
- "S" indicates the Supply Curve
- "D" indicates the Demand Curve.

Why Prices Rise And Fall — The Shifters of Supply & Demand
Non Price Factors Affecting Supply & Demand:
- Normal goods: Demand increases as income rises.
- Inferior goods: Demand decreases as income rises.
- Trends, advertising, or social influences can increase or decrease demand.
- More consumers → demand increases.
- Fewer consumers → demand decreases.
- Substitutes: If the price of a substitute rises, demand for the product increases (e.g., tea vs. coffee or Bows vs. Swords)
- Complements: If the price of a complement rises, demand decreases (e.g., printers and ink or Cars and Fuel.).
- If consumers expect prices to rise in the future, current demand increases. (This can be for many reasons, in a game it might be due to an upcoming update.)
- Subsidies or tax cuts may increase demand, this runs true in games as well as in Skyblock we have a mayor system, each mayor has their own unique perks, when the mayor that reduces all taxes shows up the demand for more expensive goods increases drastically as people have to pay less in Auction taxes or Bazaar Taxes.
Factors affecting the Supply Curve:
- Higher the costs of production (e.g., raw materials, labour, land, etc.) → Supply decreases as it costs more to manufacture the items.
- Lower the costs of production → Supply increases as it is easier to make the item.
- An increase in the level of technology makes production more efficient which makes it easier to produce goods and services which makes it so that supply increases. In a game when you increase the level of an item, it directly makes it easier to produce whatever the item is meant to produce which makes it easier to supply said item.
- The more sellers → Supply Increases
- The fewer sellers → Supply decreases
- If sellers expect prices to go up in the future they might stockpile the good and decrease supply
- In a game when prices are predicted to go up people wait to sell at the peak rather than now to maximize profit.
Taxes on producers → reduce supply.
-
Subsidies → increase supply.
-
Regulations can restrict or encourage production.
Weather/Climate (for agricultural goods):
-
Good weather → higher supply.
-
Natural disasters → reduce supply.
Elastic or Inelastic? How Prices Impact Our Decisions:
What Is Elasticity?
Elasticity is one of the most powerful tools in economics. It helps us answer questions like:
- “If the price of this item doubles, will people still buy it?”
- “Why do players rush for a sale on skins but still buy petrol no matter the price?”
In simple terms, Elasticity measures how sensitive buyers (and sellers) are to changes in price.
Price Elasticity of Demand (PED)
Definition:
PED tells us how much quantity demanded changes in response to a change in price.
-
If a small price change causes a big change in quantity demanded → Elastic
-
If demand barely changes despite price change → Inelastic
- Real world
- Elastic - Movie tickets, clothes, luxury chocolate
- Inelastic - Petrol, Medicine, Salts
- In-Game
- Elastic - Cosmetic skins, rare weapons
- Inelastic - Entry fees, repair costs, essential gear
Example: Hypixel Bazaar Flipping
Let’s say Enchanted Blaze Powder is in high demand for crafting.
-
If a price surge barely affects buying volume → Inelastic
-
But if players stop buying and wait for a cooldown → Elastic
It depends on urgency, availability of substitutes, and player strategy.
For Demand:
-
Necessity vs Luxury: More necessary = more inelastic
-
Availability of Substitutes: More options = more elastic
-
Time: Over time, demand tends to be more elastic
-
Proportion of Income: Expensive items = more elastic
For Supply:
-
Ease of Production: Easy = elastic
-
Spare Capacity: Extra resources = elastic
-
Time Period: More time = more elastic supply
Why Elasticity Matters in Both Worlds
Real World:
-
Governments tax inelastic goods (fuel, cigarettes) to raise revenue
-
Businesses lower prices of elastic products to boost demand during sales
Game World:
-
Game devs introduce limited skins or time-restricted events to play with elasticity
-
Market flippers and traders exploit knowledge of price sensitivity to profit
