Xenotransplantes cada vez mais próximos

A necessidade de órgãos humanos para transplantes se torna um problema cada vez menor com a evolução dos xenotransplantes (transplantes inter-espécies). Um dos meus temas de estudo favoritos em economia: a alocação de órgãos humanos para transplantes, novamente aqui, neste blog.

O voto é juridicamente obrigatório. Mas, efetivamente (ou, neste caso, economicamente), ele o é?

Prêmio Donald Stewart Jr

O Instituto Liberal do Rio de Janeiro (IL-RJ) está com mais uma versão do excelente concurso "Prêmio Donald Stewart Jr". Já anunciei isto aqui e acho que qualquer um que tenha lido o "O Caminho da Servidão" do Hayek (tem na biblioteca do IBMEC-MG, por exemplo) pode fazer um bom trabalho.

Quer saber sobre prêmios e tudo o mais? Confira aqui.

Outra forma de se calcular os dias de servidão

Uma outra forma de se calcular os dias de servidão (detalhes em um dos primeiros working papers de www.ceaee.ibmecmg.br) é o do IBPT. E, na metodologia deles, aparentemente, as coisas pioram (para quem paga).

Registre-se no "O Globo" e leia o resto do trecho abaixo (ou vá ao politsburger, um blog linkado aí ao lado...).

A sociedade reclama da carga tributária, mas poucos contribuintes têm noção do peso desses tributos no seu bolso e no caixa das empresas. Um estudo do Instituto Brasileiro de Planejamento Tributário (IBPT), encomendado pela Associação Comercial de São Paulo (ACSP), mostra que num salário de R$ 3 mil, por exemplo, a soma dos tributos pagos pelo trabalhador corresponde a 172 dias por ano, ou seja, mais da metade do ano. E que a soma dos tributos pagos pelo trabalhador e pela empresa que o emprega chega a R$ 2.773, o equivalente a 91% do salário.

Nesses cálculos foram considerados os impostos sobre os rendimentos, sobre o consumo de produtos e serviços e sobre o patrimônio do trabalhador, mais a parcela de tributos que as empresas recolhem sobre a folha de pagamento.

Por que devemos explorar a Lua?

Porque ela pode nos dar mais uma fonte de energia.

A potential gas source found on the moon's surface could hold the key to meeting future energy demands as the earth's fossil fuels dry up in the coming decades, scientists said Friday.

Mineral samples from the moon contained abundant quantities of helium 3, a variant of the gas used in lasers and refrigerators as well as to blow up balloons.

"When compared to the earth the moon has a tremendous amount of helium 3," said Lawrence Taylor, a director of the US Planetary Geosciences Institute, Department of Earth and Planetary Sciences.

"When helium 3 combines with deuterium (an isotope of hydrogen) the fusion reaction proceeds at a very high temperature and it can produce awesome amounts of energy," Taylor told AFP.

"Just 25 tonnes of helium, which can be transported on a space shuttle, is enough to provide electricity for the US for one full year," said Taylor, who is in the north Indian city of Udaipur for a global conference on moon exploration.

Viva o Estadão!

Finalmente eu abro um jornal - o destino é justo: só poderia ser o excelente "O Estado de São Paulo" - e vejo um gráfico no caderno de Cidades que é feito de forma tecnicamente séria.

Trata-se da matéria "Estatuto faz homicídio cair 5% em SP". Eu sou, pessoalmente, contra esta política mas, em várias ocasiões, ressaltei neste blog que, ao contrário do "oba-oba" de certos jornalistas, é importante que se publique análises sérias a respeito de temas como este.

Você vai dizer: "Cláudio, o que exatamente você quer dizer?"

Bem, o gráfico publicado na matéria não foi feito com desenhos idiotas ou com métodos bizarros. Nada disto. Ao contrário da picaretagem do status quo (presente em muitas matérias, para aumentar a não-inteligência dos leitores), este gráfico mostra uma previsão de homicídios usando o método ARIMA e o de suavização exponencial.

Meus parabéns ao jornalista Marcelo Godoy. Finalmente um gráfico sério sobre uma questão não menos importante. E um gráfico tecnicamente preciso, com análise estatística minimamente decente. Nada de "subiu-desceu-e-isto-deve-ter-a-ver-com-a-substituição-de-importações-mas-eu-ignoro-o-tema-se-você-usar-média-ou-variância". Não senhor. Desta vez o jornalismo respeitou o público. Gente que conhece mais econometria sabe dos problemas de métodos ARIMA mas também sabe que eles são melhores do que gráficos errados ou mesmo a ausência de gráficos.

Recomendo a leitura, claro.
