Informacao publicada na versao online da revista britanica "The Economist", em 15 de abril de 2013, na secao "Daily Charts".Artigo dizendo que gasto mundial no setor militar caiu 0,5% em 2012, para US$ 1,75 trilhoes. Esta foi a primeira queda desde 1998.Apesar de os Estados Unidos ainda serem responsaveis por grande parte desses gastos, a sua parcela nos gastos totais caiu, pela primeira vez desde 1991, para menos de 40%.A media mundial da relacao gastos militares / PIB e de 2,5%. Russia e Estados Unidos tem media de 4,4% cada (quase o dobro da media mundial). Durante a ultima decada, o orcamento militar chines aumentou em cerca de 175%, mas mesmo assim, ele ainda representa apenas 2% do PIB chines.Dados da revista Economist.http://www.economist.com/blogs/graphicdetail/2013/04/daily-chart-9 A revisao de estatistica (ou parte dela) ja esta online!A ideia e ir aos poucos acrescentando mais conteudo ao site. Primeiramente, vou querer levar ao fim a revisao de estatistica (que foi baseada num livro de econometria do autor alemao von Auer), e dar prosseguimento com a parte teorica deste site, com uma revisao de econometria. Por fim, serao tambem postados exemplos praticos e exercicios resolvidos.Simultaneamente a este trabalho que pretendo desenvolver, vou continuar escrevendo e postando opinioes e coisas do genero a respeito de materias economicas que eu achar interessante.Mas, calma ai, porque eu sou so um. Portanto, paciencia! Excerpt taken out of an article named "Ethanol: logic of circular biofuel trade comes into question". Posted on the online version of the Financial Times, on May, 16th, 2013.http://www.ft.com/cms/s/0/e4baefbe-b0d6-11e2-9f24-00144feabdc0.html#ixzz2TW1PlBwi...The US and Brazil, the giants of the market, together produce 87 per cent of the worlds output, according to analysts FO Licht. The US product is largely distilled from corn, while Brazil makes ethanol from its sugar cane crop. For the engine of a car, the two vintages are virtually identical. Yet in the eyes of the law they are quite distinct.This helps explain why the US and Brazil are shipping one another ethanol at great expense rather than simply using it at home.Washington is weaning its domestic ethanol industry off subsidies. In 2011 a tax credit for ethanol blenders expired, as did a corresponding import tariff.But the industry still has the support of a government mandate requiring domestic ethanol consumption to grow each year. The mandate is indirectly helping to drive imports from Brazil.The mandate, known as the renewable fuel standard, is split between volumes for traditional corn-based ethanol and advanced biofuels whose production releases less greenhouse gas impacts than ploughing fields for grain.Corn ethanol has the biggest share, but the advanced biofuel requirement is growing more rapidly.US production of advanced biofuels has not matched government expectations.To meet the mandate, fuel companies are allowed to import sugar cane ethanol, mainly from Brazil. The US Environmental Protection Agency estimates about 15.9m barrels of sugar ethanol imports will be needed this year.As the mandate grows, ethanol imports rise accordingly, say economists at the University of Missouris Food and Agricultural Policy Research Institute.Another US policy encouraging Brazil to export ethanol is set by California.
