Day 1 • Slide 7 of 8
Concept Check Income & Substitution Effects
Two psychological behaviors that explain the Law of Demand (Day 1 Section 7)
Price Drops = Power Grows!
When your food truck prices go down, customers feel like they have more money in their pocket. Their purchasing power rises, so they buy more of your food!
Price Rises = Customers Swap!
If you raise your burger prices to $18, customers will buy a different, cheaper lunch (like $5 pizza slices next door) instead of your expensive burgers.
How do you think these effects will impact your pricing choices?

Food Truck Tycoon Day 2: Trend Tracker
What happens when the market changes but your prices stay the same? Master the dynamics of Shifting Demand.
Spotting Market Shifts
Day 2 • Slide 1 of 7
Key Distinction Movement vs. Shift
It's easy to get these confused, but they are driven by entirely different triggers:
Triggered only by a change in the product's own Price. You slide along the existing curve.
Triggered by an external factor (not price!). The entire curve physically moves to a new location.
"If the price tag changes, slide. If the world changes, shift!"
A shift means consumers buy different quantities at *every* price point!
Day 2 • Slide 2 of 7
The Econ Cheat Code T.I.P.E.S.
Use the acronym T.I.P.E.S. to memorize the five core non-price determinants:
T
Viral trends, reviews, health fads.
I
What buyers can afford when wages change.
P
Cost of substitutes or complements.
E
Buyers predicting future price changes.
S
Total number of buyers in town.
If any of these change, prepare to shift!
Day 2 • Slide 3 of 7
Demand Shift Direction Shift to the Right (Increase)
Represents an INCREASE in Demand. At every single price point, people now want to buy MORE.
PBL Example: A famous food critic rates your truck 10/10. Suddenly, more customers want your food at every price!
Price ($)
Quantity (Q)
D1 D2 (Increase)
Right is ALWAYS an increase in demand!
Day 2 • Slide 4 of 7
Demand Shift Direction Shift to the Left (Decrease)
Represents a DECREASE in Demand. At every single price point, people now want to buy LESS.
PBL Example: A sudden monsoon downpour washes out the park. Total street foot traffic plummets, cutting sales at every price.
Price ($)
Quantity (Q)
D1 D2 (Decrease)
Left is ALWAYS a decrease in demand!

Food Truck Tycoon Day 3: Supply & Kitchen Costs
Step behind the grill! Discover how resource costs, kitchen speed, and prices determine your truck's ability to Supply the market.
Unlocking the Supply Side
Day 3 • Slide 1 of 6
The Business Perspective What is "Supply"?
While demand is about the *buyer*, Supply is entirely about the *seller* (you, the tycoon!). It requires:
Willingness to Sell: Are you motivated to cook and sell at a given price?
Ability to Produce: Do you have the ingredients, cooks, and truck capacity to actually make it?
If customers only want to pay $1 for a taco, you won't want to make many because you can't even cover your meat and cheese costs!
Higher prices bring higher supply!
Supply = Willingness + Ability of the Producer!
Day 3 • Slide 2 of 6
The Golden Rule for Sellers The Law of Supply
When Price Goes UP...
Sellers want to supply MORE. High prices promise massive profits!
When Price Goes DOWN...
Sellers supply LESS. Margins are tight, making production risky.
This is a direct relationship. As a business owner, you want to sell at the absolute highest possible price to capture high profits!
Price and Quantity Supplied move in the SAME direction!
Day 3 • Slide 3 of 6
Visual Tools Graphing Supply
Plotting supply is similar to demand, but with a crucial direction change:
Price ($)
Quantity Supplied (Q)
Low Price, Low Q Supply Curve (S) High Price, High Q
"Supply" starts with S & slopes Skyward (Upward)!
Day 3 • Slide 4 of 6
Operational Shocks Shifting Supply Determinants & Visuals
1. Input Costs
Meat/Boba cost goes up → profits drop → Supply decreases (Shifts LEFT).
2. Technology
High-speed turbo grill dicer installed → speed rises → Supply increases (Shifts RIGHT).
Increase in Supply (Right Shift)
S1 S2 (Increase)
Decrease in Supply (Left Shift)
S1 S2 (Decrease)
Sellers shift right for better productivity, left for higher input costs!

Food Truck Tycoon Day 4: Market Matchmaker
Bring Supply and Demand together! Find your truck's Equilibrium Price, master shortages, and manage scarcity.
Finding the Perfect Balance
Day 4 • Slide 1 of 6
The Sweet Spot Market Equilibrium
It's the point where Supply and Demand are perfectly balanced.
The price where Quantity Demanded (QD) equals Quantity Supplied (QS). Also called the market-clearing price.
Equilibrium (E) Price (P*) Quantity (Q*)
At equilibrium, there is no leftover food and no hungry, empty-handed customers!
Day 4 • Slide 2 of 6
Pricing Mistake 1 Market Surplus
If you set your food truck price above the equilibrium point:
Quantity Supplied > Quantity Demanded
You cook a massive pile of food (high QS), but consumers refuse to buy it because it is too expensive (low QD). Food goes to waste!
Price ($)
Quantity (Q)
P (High) QD QS SURPLUS Equilibrium (E)
Sellers cut prices during a surplus to clear out excess inventory!
Day 4 • Slide 3 of 6
Pricing Mistake 2 Market Shortage
If you set your food truck price below the equilibrium point:
Quantity Demanded > Quantity Supplied
A stampede of customers want your cheap food (high QD), but you run out of ingredients immediately (low QS). Lines grow long!
Price ($)
Quantity (Q)
P (Low) QS QD SHORTAGE Equilibrium (E)
A shortage signals that you are underpricing your hard work!
Day 4 • Slide 4 of 6
Econ Mastery Check Shortage vs. Scarcity
A permanent condition of humanity. Resources are physically limited (beef, water, time, cooking oil) but human desires are unlimited.
No price change can ever eliminate scarcity!
A temporary condition. Market quantity demanded is larger than quantity supplied because the price is set too low.
Adjusting prices always cures a shortage!
Remember: Scarcity is physical limits; Shortage is a price mismatch!
Day 4 • Slide 5 of 6

Analyze the following profiles. Circle whether true economic demand exists for your truck's $12 specialty burger:
Profile A: Maria
Maria hates cheese and red meat (Zero Willingness), but has a $100 bill in her purse (High Ability).
Circle: [ DEMAND ] / [ NO DEMAND ]
Profile B: David
David thinks your burger is the greatest meal in the city (High Willingness), but only has $1.50 in his bank account (No Ability).
Circle: [ DEMAND ] / [ NO DEMAND ]
Profile C: Coach Carter
Coach Carter wants to buy a healthy meal for his star athlete (High Willingness) and has a school budget credit card (High Ability).
Circle: [ DEMAND ] / [ NO DEMAND ]
7
The Law of Demand is supported by two key behaviors. Read their definitions and answer the conceptual check:
- The Income Effect: When price drops, consumers feel wealthier because they have more purchasing power left over, so they buy more.
- The Substitution Effect: When your price rises, consumers buy a different, cheaper product instead (e.g., swapping your $15 burgers for a $5 slice of pizza nearby).
PBL Challenge Prompt:
If your competitor raises their boba price to $10, explain how the Substitution Effect will help your truck's $6 boba sales:

6 Government Price Intervention
Sometimes, governments step in to set limits on prices. Review the definitions and complete the analysis:
Price Ceiling (Cap): A legal maximum price. Set BELOW equilibrium. Leads to a permanent Shortage because demand outstrips supply.
Price Floor (Base): A legal minimum price. Set ABOVE equilibrium. Leads to a permanent Surplus because suppliers overproduce but buyers refuse.
PBL Intervention Scenario:
To make street dining affordable, the mayor mandates that no food truck can charge more than $3 for items. If your equilibrium price is $6:
This limit is a: [ PRICE CEILING ] / [ PRICE FLOOR ]
This will lead to a: [ SHORTAGE ] / [ SURPLUS ]

Check your absolute understanding. For each descriptor, write "SCARCITY" or "SHORTAGE":
Food Truck Tycoon Project Guide • Day 4 Market Equilibrium Practice Completed • Page 8
Shift Right (→ Increase): When a factor makes production cheaper or easier, suppliers offer MORE items at every single price point.
Shift Left (← Decrease): When production becomes more expensive, difficult, or restricted, overall supply drops.
Supply Shifters: S.P.E.N.T.
S - Seller Count: Competitors closing up block increases market share but drops overall market supply (shifts LEFT).
P - Input Prices: Cost of wholesale cheese, meat, or paper plates. Doubling ingredient costs shifts supply curve LEFT.
E - Expectations of Producers: Predicting packaging costs will double next week makes you stockpile and cut today's supply (LEFT).
N - Net Taxes, Regs, Subsidies: Government taxes shift supply LEFT. Government subsidies (cash injections) shift supply RIGHT.

The point where consumer demand matches kitchen supply exactly. Graphically, this is the exact intersection of the downward-sloping demand curve (D) and upward-sloping supply curve (S).
Equilibrium Price (P*) The price where Qd = Qs. There are no buyers turned away, and no food goes cold.
Equilibrium Quantity (Q*) The volume of units exchanged. In our simulation, the exact quantity where lines intersect.

Setting menu prices away from the equilibrium point causes immediate market inefficiencies that cost you customers or money:
Set Price ABOVE Equilibrium
When Price is too high (P > P*):
MANAGER ACTION: Lower Menu Price!
Set Price BELOW Equilibrium
When Price is too low (P < P*):
MANAGER ACTION: Raise Menu Price!
Policy Interventions
Sometimes governments force limits on retail prices. These laws override free market equilibrium:
Price Ceiling (Legal Maximum)
Mandated cap set BELOW equilibrium (e.g., maximum $3 rent cap). Causes a permanent, artificial Shortage.
Price Floor (Legal Minimum)
Mandated base set ABOVE equilibrium (e.g., agricultural crop support floors). Causes a permanent, artificial Surplus.
Remember: "Ceilings go low; Floors go high!"
The Final Boss Distinction
These terms are often confused by non-economists, but represent completely distinct concepts:
SCARCITY
A permanent physical constraint. Natural resources (water, avocado farm land, total staff hours) are finite, while human desires are infinite. No price shift can cure scarcity!
SHORTAGE
A temporary pricing mistake. Buyers want more than sellers cook (Qd > Qs) because the price is set artificially low. Cured completely by raising prices to equilibrium!
Key Check: If changing price completely stops the "line," it was a shortage!
The A.C.E. Econ Writing Blueprint
