Explain why planting decisions are made without the information that matters.
A farmer decides in autumn what to plant. When do they learn what it will be worth?
Yes.The decision that determines the year's income is made with none of the information that will decide it: next summer's weather, next year's demand, and everyone else's planting choices.
Not quite.Contracts fix a price for part of a crop and are a genuine tool. They are agreed before anyone knows what the harvest will be, so they trade certainty for upside.
Not quite.Prices move all season and the decision cannot be unmade. A planted field is a committed one.
Farming decisions run a year ahead of their information. That single fact produces most of what looks irrational about agriculture from outside.
Put a farming year in order, and notice where the money is decided.
Tap them in order — first to last.
Choose and buy→Plant→Weather→Sell at whatever price
Costs at the start, price at the end, and a year in between.Yes.Every cost is incurred in the first two steps and the price is set in the last. The gap between them is where farm risk lives.
A crop was expensive last year, so many farmers plant it. Slide forward.

This springEverybody plants it, independently, for the same good reason.

This harvestA glut. The price collapses, and the same farmers now avoid it next year.
Every farmer made a sensible decision. Why was the outcome bad for all of them?
Yes.It is the classic agricultural cycle: high price, everyone plants, glut, low price, everyone avoids it, shortage. Nobody is being foolish — the signal each is following is a year out of date by the time it matters.
Not quite.Knowing better means predicting what thousands of other farmers will independently decide. Some try; the cycle persists.
Not quite.The weather was fine. That is what produced the glut.
Move the control to see what changes.
Which of these reduce a farm's exposure to that cycle?
Agreeing a price before planting.
Growing several different crops.
Insurance against yield loss.
Planting more of whatever paid best last year.
Working harder.
Yes.Everything that works either fixes the price early or spreads the bet. Nothing that works is about effort — a perfectly grown crop into a collapsed market is still a loss.
Planted area rises 45% and the price falls from 180 to 75. If a farm's yield is unchanged, what percentage of last year's revenue does it earn?
%
Yes.75 ÷ 180. The same crop, the same work, the same field — and well under half the income, decided entirely by what everybody else planted.
Lesson complete
Farming decisions are made a year before the information that decides them.
