The pier closes for repairs and the Waterfront empties. The city announced it a day ahead, to every truck in town. Only some of them read it. No business is an island, and no truck is either.
Learning objectives. After this week you can (1) tell micro decisions apart from the macro environment; (2) read the signals your arena publishes; and (3) trace a signal to the line of your Daily Report it touches.
Remember this: you can't control the weather, but you can read the forecast.
1) Micro and macro
Microeconomics is your truck and its market. Macroeconomics is the whole economy above it: inflation (a general rise in prices), the interest rate (the price of borrowing money), consumer confidence and unemployment. Street food is discretionary spending, among the first things people cut when confidence falls. Analysts scan these forces with a PEST analysis: political, economic, social and technological.
2) The signals in your arena
Every section gets the city bulletin: conventions, street fairs, closures, permit hikes and supplier price swings, announced one day ahead on your arena page and Daily Report. If your section trades in the Extrapoli Universe, the Extrapoli Daily also arrives every morning at 9 AM, before the 5 PM close, with macro dials, cost indices for food, labor and fuel (1.00 = normal), and a desk of tonight's operating numbers. Its rumor column prints a confidence score and is allowed to be wrong.
3) From signal to ledger line
Today's Cost = Normal Cost × Index
The food index prints 1.15. A burger costing $3.20 now costs 3.20 × 1.15 = $3.68, so at $8.50 the margin falls from $5.30 to $4.82. A labor index of 1.10 turns a $200 staffer into $220. A demand print of 112% on a day you would expect 133 main items points to about 133 × 1.12 ≈ 149; a print near 100% is just a normal day. A street fair touches your traffic; a permit hike touches your Fixed line.
Separate the level (today's number) from the trend (where it is heading). One day's print is not a reason to rebuild your season.
Quick self-check
(a) Food index 1.10: an item costing $2.10 and selling at $6.50 has what margin? (b) Labor index 1.15: what does a $200 staffer cost? (c) Confidence slides: which kind of spending is cut first? (Answers: 2.10 × 1.10 = $2.31, so $4.19; $230; discretionary spending, like street food.)
Common mistakes
- Trading on rumors. The confidence score is printed for a reason.
- Reading the news after the close. A signal read tomorrow is history.
- Using the environment as an excuse. Every truck faced the same news; reading it is the edge.
This week in the arena
Each day, write down one outside signal (a bulletin item, or a Daily index if your section has one) and the Daily Report line it should touch. Next morning, check that line. Report one signal that landed the way it was announced, with the numbers.
