Expropriações normativas

Esta dissertação busca investigar as consequências jurídicas das expropriações normativas. Trata-se de um ato regulatório, genérico e abstrato, que subtrai ou minimiza o direito de propriedade, do qual não decorre a transferência formal do domínio para Poder Público. A problemática tem lugar na medida em que essa ablação normativa é levada a efeito, sem o estabelecimento do devido processo legal expropriatório (previsto no art. 5º, inciso XXXIV, da Constituição da República – CRFB), o qual impõe o pagamento de uma prévia e justa indenização ao expropriado. Para este fim, será investigado se os institutos por meio dos quais o Estado intervém na propriedade privada (desapropriação, limitação administrativa, ocupação temporária, requisição administrativa, tombamento) dão conta desse fenômeno, ou se se trata de uma falha da regulação, que produz consequências jurídicas. Ao final, será apresentada uma proposta, de lege ferenda, de disciplina desse fenômeno

Ownership, control and corporate valuation of Brazilian companies

We study the direct and indirect ownership structure of Brazilian corporations and their market value and risk by the end of 1996 and 1998. Ownership is quite concentrated with most companies being controlled by a single direct shareholder. We find evidence that indirect control structures may be used to concentrate control even more rather than to keep control of the company with a smaller share of total capital. The greater the concentration of voting rights then less the value of the fmn should be due to potential expropriation ofrninority shareholders. We fmd evidence that when there is a majority shareholder and when indirect ownership structures are used without the loss of control, corporate valuations are greater when control is dilluted through the indirect ownership structure. This evidence is consistent with the existence of private benefits of control that can be translated as potential minority shareholder expropriation.

Lifestyle factors, direct and indirect costs for a Brazilian airline company

OBJECTIVE: To analyze lifestyle risk factors related to direct healthcare costs and the indirect costs due to sick leave among workers of an airline company in Brazil. METHODS: In this longitudinal 12-month study of 2,201 employees of a Brazilian airline company, the costs of sick leave and healthcare were the primary outcomes of interest. Information on the independent variables, such as gender, age, educational level, type of work, stress, and lifestyle-related factors (body mass index, physical activity, and smoking), was collected using a questionnaire on enrolment in the study. Data on sick leave days were available from the company register, and data on healthcare costs were obtained from insurance records. Multivariate linear regression analysis was used to investigate the association between direct and indirect healthcare costs with sociodemographic, work, and lifestyle-related factors. RESULTS: Over the 12-month study period, the average direct healthcare expenditure per worker was US$505.00 and the average indirect cost because of sick leave was US$249.00 per worker. Direct costs were more than twice the indirect costs and both were higher in women. Body mass index was a determinant of direct costs and smoking was a determinant of indirect costs. CONCLUSIONS: Obesity and smoking among workers in a Brazilian airline company were associated with increased health costs. Therefore, promoting a healthy diet, physical activity, and anti-tobacco campaigns are important targets for health promotion in this study population.
