 The incomes from the revenue stamp created a surplus in the university finances , which were poorly administrated . Excessive amounts of the budget were directed to the establishment of research institutes and centers , creation of new professorial chairs , and the construction of several buildings , the establishment of a technological infrastructure , including Internet access , creating a deficit in the universities accounts . This situation , together with the increasing cost of the retirement plans and the delay in its payments , were the causes of the financial and institutional crisis of 1998 , which ended in the closure of the university in the second semester of 1998 and the suspension of payment to all the academic and administrative staff members .
