TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN ECONOMÍA / Sleeping is probably the most frequent consumption and investment activity of humans, but it has been relatively understudied in economics. In this paper we use a time use global dataset and test competing theories to explain the differences in sleeping time between the rich and the poor around the world. We find that high income full-time workers tend to sleep less than those of low-income. Average estimates show a 10-20 minute lower sleep for the top quartile vis-a-vis poorer quartile of full-time workers. This stylized fact is robust to several covariates using panel data regressions, holding both across countries and, most importantly, within the countries in our sample. Furthermore, the observed negative covariation of income and sleep among workers, is consistent with a potential substitution effect with several leisure activities, like commute, surfing on the internet and outside socializing activities, all of which are also positively (and significantly) correlated with household income.

El objetivo de la presente investigación fue explorar las relaciones entre el aprendizaje autorregulado, el manejo del tiempo y la búsqueda de ayuda académica en estudiantes del primer año de estudios. Participaron 324 estudiantes universitarios del primero año (M = 18.5 años, DE= 1.5 años), quienes contestaron tres cuestionarios: el Inventario de Procesos de Autorregulación del Aprendizaje [IPAA], el Time Management Behaviour Questionnaire [TMBQ] y el Motivated Strategies for Learning Questionnaire [MSLQ]. Los resultados indicaron que existe relación entre las dimensiones del manejo del tiempo, la búsqueda de ayuda y el aprendizaje autorregulado. De modo que a un manejo del tiempo más efectivo y a mayor búsqueda de ayuda, se presentan mayores puntajes de aprendizaje autorregulado. Se discuten las implicancias de estos resultados a un nivel de educación superior. / The main purpose of this study was to investigate the relationships between self regulation, time management and academic help seeking in students from the first year of university. The data was collected from 324 first year university students (M = 18.5, SD= 1.5), won answer to three diferent questionnaires: el Inventario de Procesos de Autorregulación del Aprendiza [IPAA], the Time Management Behaviour Questionnaire [TMBQ] and the Motivated Strategies for Learning Questionnaire [MSLQ]. The results revealed that there is a relationship between the dimentions of time management, academic help seeking and the self- regulated learning. Therefore, to more effective time management and a greater search for help, higher self- regulated learning scores are presented. Finally, the implications of these results at a higher education level are discussed.
