Inferring Worker Preferences in the US Historical Model (Figure 3.16)
In the model of US labor choices shown in Figure 3.16, worker preferences are not directly measurable. Instead, they are inferred from the observed historical data. The model assumes that the choices made in 1900 (Point A) and 2020 (Point D) were optimal. Therefore, the indifference curves are constructed as a 'best guess' to be tangent to the respective budget constraints at these chosen points, representing the preferences that would explain these actions.

Learn After
An economic model is built to understand changes in an average worker's choices between daily consumption and daily free time at two different points in history, 1900 and 2020. For each year, researchers use historical wage data to construct a budget constraint showing all possible combinations of consumption and free time. They also identify the specific combination that was actually chosen, on average, in each of those years. Given that the researchers cannot directly measure the subjective feelings or preferences of workers from the past, what is the most logical method for them to represent worker preferences within this model?
Modeling Historical Labor Preferences
Identifying Financial Instruments
In an economic model that represents historical choices between work and leisure, the indifference curves that show worker preferences are drawn based on a general theory of behavior, and then the observed historical data points are plotted to see how well they fit these pre-drawn curves.
Inferring Preferences from Choices
An economist models the historical choices of an average worker at two points in time: 1900 and 2020. For each year, a 'budget constraint' is drawn showing the possible combinations of daily income and free time. The model shows that in 1900, the worker chose Point A (less income, less free time), and in 2020, the worker chose Point D (more income, more free time). The economist cannot directly measure the workers' subjective preferences but assumes that the observed choices (A and D) were the best possible ones for the workers in their respective years. What is the primary purpose of making this assumption in the model?
Evaluating the 'Revealed Preference' Assumption in Historical Economic Models
An economist is creating a model to compare the choices between daily income and free time for an average individual in two different historical periods. The economist uses historical data to determine the budget constraint (all possible combinations of income and free time) and the actual combination that was chosen in each period. To represent the individual's preferences, the economist draws indifference curves that are tangent to the budget constraints precisely at these observed historical choice points. Which of the following statements best justifies this methodological approach?
An economist models the historical choices of an average worker. For a specific year, the budget constraint is drawn, representing all possible combinations of daily income and free time. The economist then plots the observed average choice, Point X, and discovers that it lies inside the feasible set, not on the budget constraint line itself. Based on the foundational assumptions of this type of choice model, what does this finding imply?
