The Shape of the Survival Constraint
In a model where a farmer's grain consumption is plotted on the vertical axis and her hours of free time per day are on the horizontal axis, the 'biological survival constraint' shows the minimum grain she needs to survive. Explain the economic and biological reasoning for why this constraint line slopes downwards as hours of free time increase (i.e., why she needs less grain to survive when she has more free time).

In a model of an interaction between a landowner and a landless farmer, the farmer's survival depends entirely on receiving a minimum amount of grain from the harvest. Imagine a technological innovation, like a solar-powered water purifier, becomes available for free. This innovation significantly reduces the farmer's risk of illness, thereby lowering the minimum caloric intake she needs to survive. How does this change affect the 'biologically feasible set' of outcomes (the combinations of free time and grain that allow the farmer to survive)?

The Shape of the Survival Constraint
Consider a model where a landless farmer's only source of nutrition is the grain she receives from a landowner. If a government program is introduced that provides the farmer with just enough food to meet her minimum biological survival needs, then the 'survival constraint' (the minimum amount of grain she must receive from the landowner) is no longer a relevant factor in determining the feasible outcomes of their interaction.

In a model of an interaction between a landowner and a landless farmer, the farmer needs a minimum of 4 bushels of grain to survive. The farmer's work directly translates into grain production. If she works for 8 hours a day, she produces a total of 10 bushels of grain. The landowner proposes a contract where the farmer works 8 hours a day and receives 3.5 bushels of grain as her share. Based on the farmer's biological needs, which of the following statements is correct?
In a model of a landless farmer whose only source of food is the grain she produces, the 'survival constraint' represents the minimum amount of grain she needs to live. This minimum amount is not a fixed number; it increases as she spends more hours working. What is the most direct explanation for why the farmer's minimum survival requirement for grain increases with her hours of work?
In a model where a landless farmer's survival depends on the grain she receives from a landowner, the 'survival constraint' shows the minimum grain she needs for any given number of work hours. Match each scenario below with its most likely effect on this survival constraint.
