Uma análise econ?mico-atuarial dos death bonds
Carvalho, Joo Vinícius de Frana;Afonso, Luís Eduardo;
Revista Brasileira de Economia , 2012, DOI: 10.1590/S0034-71402012000200003
Abstract: a death bond is issued by a financial institution to buy a life insurance policy from an insured who wishes to receive funds during his lifetime. this work presents the pricing of death bonds for both genders and different ages of the initial contract, using actuarial modeling techniques. initial results show little attraction for the bonds’ investors. an extension of the model shows that if investors can identify the individuals with the worst health conditions, the returns are substantially higher and the standard deviations are quite low.

Abstract: the recently described fish species, astyanax altiparanae (tetra) is common in the upper rio paraná basin, and has been reported in the igua?u basin. however, its natural origin in the rio igua?u is questionable. in the present work, karyotypical and morphological features of two populations of astyanax altiparanae from the upper rio tibagi and upper rio igua?u were compared. both populations showed 2n=50 chromosomes and differences in their karyotype formula, nor-bearing chromosomes and location of heterochromatin. morphometric data from both populations were analyzed through free-size canonical variables. cytogenetic and morphological results were mostly coincident showing exclusive markers that reflect their degree of populational isolation. in addition to other geographic, morphological and molecular data for a. altiparanae populations from the lower rio igua?u and rio paraná tributaries upstream from the itaipu dam (south brazil), the present results indicate that the two populations analyzed in this study belong to different stocks. the presence of this species along the rio igua?u basin would be a consequence of a complex and poorly understood evolutionary history.
