Using the only national time use survey in Chilean cities (2015) we analyze the weekly assignment of time of individuals, aimed at revealing the hierarchy and substitutions that underlay the observed time assignment, controlling for the effect of socioeconomic variables. This is achieved by means of a model that captures the effects of both types of variables simultaneously, isolating the pure substitution effects between activities and detecting their hierarchy. We find that the differences across genders—universally observed—regarding time assigned to paid and unpaid labor, and to sleep, happens due to a reduction in time assigned to leisure by women. We also find that an inhabitant of the capital city—about six times larger than the second in population—substitutes sleep and leisure time for time assigned to transportation, to all types of work, and to eating. Leisure exhibits strong substitution with transportation, and also with time assigned to work (paid and unpaid), to study, and to eating.

利用智利城市唯一的全国时间使用调查（2015），我们分析了个人每周的时间分配，旨在揭示观察到的时间分配背后的层次结构和替代，并控制社会经济变量的影响。这是通过一个模型来实现的，该模型同时捕获两种类型变量的影响，隔离活动之间的纯粹替代效应并检测其层次结构。我们发现，性别之间在分配给有酬和无酬劳动以及睡眠的时间方面存在差异（普遍观察到），这是由于女性分配给休闲的时间减少所致。我们还发现，首都城市的居民（人口数量大约是第二个城市的六倍）用睡眠和休闲时间取代了分配给交通、各种工作和饮食的时间。休闲对交通以及分配给工作（带薪和无薪）、学习和吃饭的时间具有很强的替代性。
