Saudades da culinária japonesa na pandemia? R neles!

Isolamento social e R: o que poderia dar errado?

Testei o pacote ARDL com dados de busca (abrangência mundial) pelos seguintes termos: Lamen, Gyoza, okonomiyaki e sunomono. O gráfico, ainda com alguns problemas no eixo (não tive tempo de ajustar as datas, mas o período é: 2004.01-2020.06), mas eis a cointegração.

Ah, sim, o código para obter a relação de cointegração – e outros detalhes – são uma mera adaptação do código original do exemplo do autor do pacote.

library(ARDL)
df<-read.table("C:/Users/cdshi/OneDrive/Documents/Meus Documentos/sunomono.csv",
               header=TRUE, sep=",",na.strings="NA", dec=".", strip.white=TRUE)

models <- auto_ardl(Lamen~Gyoza+sunomono+okonomiyaki, data=df, max_order=4)
models$top_orders
models$best_model
ardl_1402<-models$best_model
summary(ardl_1402)

uecm_1402 <- uecm(ardl_1402)
summary(uecm_1402)

bounds_f_test(ardl_1402, case = 2)

tbounds <- bounds_t_test(uecm_1402, case = 3, alpha = 0.01)
tbounds

tbounds$tab

multipliers(ardl_1402)

ce <- coint_eq(ardl_1402, case = 2)

 

Modelo simples para entender a pandemia

Está aqui. Mas você tem que usar o google translate (que está na própria página, na coluna da direita), exceto se entender dinamarquês.

Ameaça não-crível em jogos repetidos

A infância nos anos 70

Tive infância na época. Descobri que, a despeito das dificuldades, vivi em uma época em que os brinquedos não vinham da China.

Os melhores carrinhos eram os ingleses. Acho que formavam a imensa maioria dos carrinhos ofertados (achei até um de Hong Kong).

Existiam alguns nacionais (na foto, o carro esportivo cinza) e, quando algum japonês retornava ao Japão, ganhávamos algumas lembranças, como a viatura e o ônibus da polícia que estão na foto.

Cartéis são instáveis? Beba uma antes de ler isto!

Em setembro de 1931, a Brahma propusera aos seus concorrentes um pacto de preços para as vendas no interior em que as cervejas de primeira qualidade seriam vendidas a 78$000 a caixa com quatro dúzias, ou seja, 1$625 a unidade. Acima, portanto, do preço unitário médio praticado pelas cervejarias até então. Passados três meses, em novembro, cartas dos viajantes informam que o acordo não se sustentava e os viajantes das fábricas concorrentes lançavam mão de todos os recursos para conquistar a freguesia. A Hanseática, por exemplo, enviara um carregamento de três vagões de cerveja que foram vendidas a preços da tabela antiga. Em consequência, os mercado de Barra do Piraí, importante entrocamento da Estrada de Ferro Central do Brasil, ficou abarrotado de cervejas da Hanseática. Outros viajantes ofereciam mobiliário para os bares, uns recompravam os vasilhames vazios a preços inferiores aos da tabela combinada entre as cervejarias, também se ofereciam desconto de fretes e prazos de pagamento dilatados.

Parabéns aos nikkeis.

Por que esconder a obra de Thomas Sowell?

Pois é. Uma boa pergunta. Por que a AEA não recomenda a leitura do Sowell?

Trecho do artigo:

To name just a few of his many works specifically on this theme: Race and Economics (1975), Markets and Minorities (1981), Ethnic America: A History (1981), The Economics and Politics of Race (1983), Preferential Policies (1990), Race and Culture (1995), Migrations and Cultures (1996), Conquests and Cultures (1998), Affirmative Action Around the World (2004), Black Rednecks and White Liberals (2005), Intellectuals and Race (2013), Wealth, Poverty and Politics, (2016), and Discrimination and Disparities (2018, revised ed., 2019).

Não é pouca coisa. Talvez falte ali uma econometria. Mas a teoria importa, não? A propósito, outra ausência na lista citada é a de Gary Becker.

A regra que seu criador mais desobedece

E é uma ótima regra.
