## 经济代写|劳动经济学代写Labor Economics代考|Indifference Map

It is useful to consider an indifference map, which is a whole family or field of indifference curves, as shown in Figure 2.2. Each curve reflects some different level of total utility, much as each contour line on a topographic map reflects a different elevation. Figure $2.2$ illustrates only three of a potentially unlimited number of indifference curves. Every possible combination of income and leisure will lie on some indifference curve. Curves farther from the origin indicate higher levels of utility. This can be demonstrated by drawing a $45^{\circ}$ diagonal from the origin and noting that its intersection with each successive curve denotes larger amounts of both income and leisure. The $y_2 l_2$ combination of income and leisure is preferred to the $y_1 l_1$ combination because the former indicates larger amounts of both income and leisure. Similarly, the $y_3 l_3$ combination entails greater total utility than $y_2 l_2$, and so on. ${ }^1$ It is evident that an individual will maximize total utility by achieving a position on the highest attainable indifference curve.

Just as the tastes of consumers for specific goods and services vary greatly, so do individual preferences for work and leisure. Different preferences for the relative desirability of work and leisure are reflected in the shape of one’s indifference curves. In Figure 2.3(a), we present the indifference curves of a “workaholic” who places a low value on leisure and a high value on work (income). Note that the workaholic’s curves are relatively flat, indicating that this individual would give up an hour of leisure for a relatively small increase in income. Figure 2.3(b) shows the indifference curves of a “leisure lover” who puts a high value on leisure and a low value on work (income). Observe that this individual’s indifference curves are steep, which means that a relatively large increase in income must be realized to sacrifice an hour of leisure. In each case, the indifference curves are convex to the origin, but the rate of decline of MRS $L, Y$ is far greater for the leisure lover than for the workaholic.

Why the differences? First, it may be purely a matter of tastes or preferences rooted in personality. A second and related point is that the occupations of individuals differ. The flat curves of Figure $2.3$ (a) may pertain to a person who has a creative and challenging occupation-for example, a painter, ceramist, or musician. Such work entails little disutility, and hence it takes only a small increase in income to induce the artist to sacrifice an hour of leisure. Conversely, an unpleasant job in a coal mine or on an assembly line may elicit steep indifference curves. Such work involves substantial disutility, and a large increase in income is required to induce one to give up an hour of leisure. Finally, an individual’s personal circumstances may affect his or her relative evaluations of labor market work and leisure. For example, a young mother with two or three preschool children or a college student may have relatively steep indifference curves because “leisure” (non-labor market time) is valuable for child care and studying. Similarly, José may be married and, therefore, may have substantial financial obligations. Consequently, his indifference curves are relatively flat: He is quite willing to give up leisure for income. On the other hand, John is single and his financial responsibilities are less compelling. He is less willing to give up leisure for income, and his indifference curves are, therefore, relatively steep. In short, personality, the type of work under consideration, and personal circumstances may influence the shape of a person’s indifference curves.
