Reshaping the schooling system: The role of immigration

This paper studies how the schooling system may be impacted by the number and skill type of immigrants. When the number of low-skilled immigrants is large, the education regime tends to become segregated. Wealthy locals are more likely to choose private schools and vote for a lower tax rate to finance public education. In contrast, high-skilled immigrants tend to reinforce the public system. The optimal immigration policy is highly skill-biased. The admission of high-skilled immigrants expedites redistribution toward the less-skilled local households through both a stronger fiscal support for public education and a reduction in the skill wage premium.

Public education expenditures and private school enrollment

In this paper, I investigate whether increases in public education expenditures lead to reductions in private school enrollment. In order to deal with the endogeneity of public expenditures, I use as a natural experiment the 1998 FUNDEF reform in Brazil that caused exogenous variations in local public school funding. Using data from Brazilian School and Population censuses, I show that public education expenditures increases are associated with reductions in the share of private school enrollment for grade 1. However, the effect is smaller for grades 2 to 4, which is consistent with the existence of costs associated with switching schools.

Epidemiologic analysis of prevalence of the hyperhidrosis

Background The present paper aims to study the prevalence of the various manifestations of hyperhidrosis in patients who sought treatment in a specialized ambulatory in the state of São Paulo. Objectives Opposite to previous studies, this paper studies the different combinations of sweating sites, not being restricted to the main complaint site of the patients, but taking into consideration secondary complaints patients may present. Methods This was a retrospective approach of a database containing more than 1200 patients in which were mapped: combination of sweating sites, age of onset, age spectrum, mean age, body mass index and gender of patients. Patients were categorized into four groups based on their main sweating site - palmar, plantar, axillary and facial. Results We concluded that hyperhidrosis appears frequently in more than one site, being the main complaint that affects the most patients palmar hyperhidrosis, which appears early in the patients during adolescence. When there are two sites of sweating, the most frequent combination is palmar + plantar, and when there are three sites of sweating the most frequent combinations are palmar + plantar + axillary and axillary + palmar + plantar. Study limitations This research has casuistics limited to a single care service for patients with hyperhidrosis. Conclusion It is necessary to keep in mind that the disease manifests itself mainly in more than one location, with different intensities in each of the patients, generating a significant impairment of their quality of life.

Mortality risks and child labor

In this paper, we investigate the role of young adult mortality on child labor and educational decisions. We show that, in the absence of appropriate insurance mechanisms, the level of child labor is inefficient. It may be too high if parents are not very altruistic and anticipate positive transfers from their children in the future, but it can also be too low, in particular when parents expect to make positive transfers to their children in the future. Imperfect capital markets unambiguously increase the equilibrium level of child labor. We also show that a cash transfer conditional on childs schooling can always restore efficiency regarding child labor.
