摘要：The paper collects the results of a survey performed in 2010 aimed at analysing how high school students in theprovince of Messina in Sicily (Italy) spend their time. Principally, is analyzed the interaction between use oftime, scholastic performance and time dedicated to study. So, we propose an estimation model for the dailystudy-time of students. From a methodological point of view, using a two stage regression procedure to estimateself-rate performance (Srpe) and time devoted to study (Tstu) allows to correct the estimates by simultaneity effectsbetween these variables. In the first stage, the self-rate performance at school is estimated in a reduced formand is used as a proxy of scholastic performance in the second step. Next, we run an ordinal regression in orderto estimate the hours dedicated to study declared by the student. The results obtained show that students with ahigh expected value of study-time come from lyceum, they are mostly females, and tend to read more. Furthermore,they have satisfactory scholastic performance, are helped by their mothers when they do their homework,have a lower-than-average age difference with their mothers, but a higher-than-average age difference with theirfathers
