Dinamica EGO 1.6 já está disponível.
É com satisfação que comunicamos o lançamento da versão 1.6 de Dinamica EGO (Ambiente para Objetos de Geoprocessamento).
A plataforma de modelagem de Dinamica EGO apresenta excelentes possibilidades para o desenho de modelos espaciais, desde modelos analíticos aos extremamente complexos e dinâmicos, os quais podem envolver iterações aninhadas, retro-alimentações dinâmicas, abordagem de muit-escalas e multi-regiões, manipulação e combinação algébrica de dados em vários formatos, tais como mapas, tabelas, matrizes e constantes -, processos de decisão para bifurcar e juntar fluxos de execução, mais uma série de algoritmos complexos para análise e simulação de fenômenos de natureza espaço-temporal.
Os operadores do Dinamica EGO, chamados functores, são seqüenciados na forma de um gráfico para se estabelecer um fluxo de dados. Através da interface gráfica, modelos são criados simplesmente arrastando e conectando os functores pelos seus portos, os quais representam conectores para tipos de dados. Portanto, modelos podem ser concebidos na forma de um diagrama que tem sua execução de acordo com uma cadeia de processamento de dados. Em suma, essa inovadora e amigável interface gráfica permite a concepção criativa de modelos que verdadeiramente podem representar a complexidade de vários fenômenos geográficos.
Principais novas funcionalidades da versão 1.6
* Suporte para 64 bit: Dinamica EGO pode ser instalado como um programa nativo de 64-bits no Windows Seven 64 e Vista 64.
* Novo lançador de console que permite adicionar modelos para rodá-los sequencialmente.
* Compilação de expressões nativas: Expressões de cálculo de mapas podem ser compiladas em código nativo e com isso aumentar sua performance.
* Ferramenta de otimização de modelos baseada em Algoritmos Genéticos.
* Nova interface gráfica com janelas flutuantes

China’s size, high rate of growth, and increasing outward orientation mean that its emergence is surely changing international prices, improving the terms of trade for countries that produce its importables and deteriorating the terms of trade for countries that produce its exportables. Mexico fits squarely in the latter camp, whereas Argentina, Brazil, Chile, Colombia, and Peru fit in the former.

Prezado Prof.,63 anos e ainda cara-de-pau! Bem, mas não pára por aí. O meu amigo, debochado, respondeu:
Tenho 63 anos e sou aluno do Curso de Economia, aqui em Fortaleza, Ceará.
Peço, por gentileza, resolver a questão abaixo:
"Suponha que, para uma determinada economia, durante um certo período, os investimentos tenham sido iguais a 100, que os gastos do governo tenham sido iguais a 75, que os impostos líquidos tenham sido fixados em 100 e que o consumo (C) tenha sido expresso pela função consumo C = 25 + 0,8Yd, onde Yd é a renda disponível e Y é o PIB.
a) Qual é o nível de renda de equilíbrio (Y)?
b) Qual é o valor do multiplicador dos gastos do governo (∆Y/∆G)? E o multiplicador dos impostos (∆Y/∆T)?
Suponha que os investimentos tenham caído em 40 unidades, para um nível de 60. Qual será o novo nível de renda de equilíbrio?"
Abraços,

Why so much BS in the corporate world?Ainda sobre a vida nas organizações, este paper (via Tim Harford) mostra como as pessoas são motivadas por um cartão de agradecimentos, um aperto de mão e um título de seu cargo.
My speculation: People disagree in corporations, often virulently, or they would disagree if enough real debates were allowed to reach the surface. The use of broad generalities, in rhetoric, masks such potential disagreements and helps maintain corporate order and authority.

"Economic geography and African development
Physical and economic geography both contribute to low levels of income in Africa. The small size of African countries and markets impedes growth through a number of mechanisms. The business environment is prone to monopoly and opportunistic behaviour. Cities are relatively small. Public goods (national and regional are undersupplied). The potential benefits of natural resources are not dispersed widely enough. Growth prospects require better use of natural resource revenues and the development of clusters of export oriented manufacturing in coastal economies."
Economic migrants from the countryside and neighboring provinces have swelled Chongqing at a rate of between 500,000 to 1 million people every year.
"This paper deals with institutional persistence in long-term economic development. We investigate the historical record of education in one of the fastest growing and most unequal societies in the twentieth century – the state of São Paulo, Brazil. Based on historical data from an agricultural census and education statistics, we assess the role played by factors such as land concentration, immigration and type of economic activity in determining supply and demand of education during the early twentieth century, and to what degree these factors help explain current educational performance and income levels. We find a positive and enduring effect of the presence of foreign-born immigrants on the supply of public instruction, as well as a negative effect of land concentration. Immigrant farm-laborers established their own community schools, and pressured for public funding for those schools or for public schools. The effects of early adoption of public instruction can be detected more than one hundred years later in the form of better test scores and higher income per capita. These results are suggestive of an additional mechanism generating inequality across regions: the places that received immigration from countries with an established public education system benefited from an earlier adoption of the revolutionary idea of public education."

... the academic studies that have looked into this question failed to find evidence either for the Dutch Disease of the deindustrialization thesis (See Puga, 2007; Barros and Pereira, 2008; Jank et al., 2008; Nassif, 2008; Souza, 2009; Bonelli and Pessoa, 2010). Non-commodity-related-industries are finding harder than before to maintain their exports growing, but they have plenty of room for expansion in a rapidly growing and still well-protected domestic market.A conclusão:
Academics point to the obvious, beyond the immediate policy-mix issue—Brazil’s low savings rates and persistent government budget deficits. Were savings higher and deficits lower, interest rates could be reduced without risking higher inflation and providing room for a more competitive exchange rate. Without such austerity, however, the country seems condemned to a less-than-par potential GDP growth rate that may lead to increasing discomfort with current macroeconomic policies, and stronger appeal of long-abandoned populist policies.

"There is no reason why, in a society which has reached the general level of wealth ours has, the first kind of security should not be guaranteed to all without endangering general freedom; that is: some minimum of food, shelter and clothing, sufficient to preserve health. Nor is there any reason why the state should not help to organize a comprehensive system of social insurance in providing for those common hazards of life against which few can make adequate provision"Pois é, o Hayek é menos austríaco do que se pensa.
Taxation, Lobbies and Welfare in an Enclave Economy: Rubber in the Brazilian Amazon 1870-1910O mais bacana, contudo, foi descobrir que ele está na Harvard Business School. Parabéns!!!
Abstract
This paper uses an enclave economy (Brazilian Amazon) to show that [export] taxes can be welfare enhancing and be used as instruments to move the economy away from the immiserizing growth path. Nonetheless, the results show that the government could have raised the Brazilian Amazon's welfare with a much higher export tax, and offers political-economic reasons why it did not.
Brazil is frequently portrayed as exhibiting persistent and structural economic inequality that is rooted in the early colonial experience, and is believed to undermine development in the long run. I construct original measures of agricultural inequality for 1905 in what is today Brazil’s largest state, using farm-level micro data for some 50,000 farms. Using these measures of inequality, along with contemporary covariates and other historical variables I assess the impact of colonial institutions, slavery, farm inequality, and political inequality on long-term development in São Paulo. The principal findings are: (1) a potentially coercive colonial institution, the aldeamento, is positively correlated with income per capita at the end of the twentieth century; (2) measures of the intensity of slavery have little if any independent impact on income in 2000; (3) farm inequality was not persistent in São Paulo at the county level over the twentieth century; (4) in both OLS and IV estimates, no negative effect can be found for 1905 inequality on long-term development; (5) political inequality in the early twentieth century, measured by the extent of the franchise, is unrelated to contemporary farm inequality, and also unrelated to long-term economic growth; and (6) the provision of local public goods in the early twentieth century, measured by local public education outlays, has a positive impact on long-term development, but was not related to contemporary economic or political inequality. Overall, neither the intensity of slavery nor the pattern of inequality had any discernable negative economic impact in the long run.

The chief of the Cassanga used the “red water ordeal” to procure slaves and their possessions. Those accused of a crime were forced to drink a poisonous red liquid. If they vomited, then they were judged to be guilty. If they did not vomit, they were deemed not guilty. However, for those that did not vomit this usually brought death by poisoning. Their possessions were then seized and their family members were sold into slavery."The Long Term Effects of Africa's Slave Trade" Quarterly Journal of Economics, Vol. 123, No. 1, February 2008, pp. 139-176.
"... new economic geography has a kind of steampunk feel, so that the stories it tells seem more suited to the U.S. economy of 1900 than that of 2010. Well, China is an economic powerhouse, but it’s still quite poor; .., China today appears to have roughly the same level of per capita GDP as the United States at the beginning of the 20th century.
And guess what? Chinese economic geography is highly reminiscent of the economic geography of advanced nations circa 1900 – and it fits gratifyingly well into the new economic geography framework."
