decrease the total revenue of wheat farmers
If the government removes a binding price floor from a market, then the price paid by buyers will
decrease, and the quantity sold in the market will increase
Good news for farming can be bad news for farmers because the
demand for basic foodstuffs is usually inelastic, meaning that factors that shift supply to the right decrease total revenues to sellers

direction and magnitude of the effect
