Análise de sentimento do COPOM com R (parte 1: usando a base de dados)

Inspirado no artigo “Quando as palavras contam a história”, do Terraço Econômico, resolvi elaborar minha própria implementação do método, contribuindo para a comunidade. Vou mostrar então como eu fiz em alguns posts dessa série:

  1. Usando a base de dados
  2. Replicando a base de dados
  3. Analisando o sentimento

Resolvi começar pelo final, divulgando a base de dados já pronta, para que os colegas possam já começar a criar suas próprias análise, nuvem de termos, contagem de palavras, etc.

ARQUIVO: OCDE vs. Peer Review

Nosso método de divulgação já está ultrapassado.

Peer review has its place. But peer reviewers have blind spots. If you want to really review a paper, you need peer reviewers who can tell you if you’re missing something within the literature—and you need outside reviewers who can rescue you from groupthink. If you’re writing a paper on himmicanes and hurricanes, you want a peer reviewer who can connect you to other literature on psychological biases, and you also want an outside reviewer—someone without a personal and intellectual stake in you being right—who can point out all the flaws in your analysis and can maybe talk you out of trying to publish it.

80 Economic Bestsellers before 1850: A Fresh Look at the History of Economic Thought

Lista interessante de livros clássicos de economia, famosos no seu tempo (antes de 1850), mas negligenciados hoje.

Developing Economics

This new Working Paper studies the economics books which – judged by the number of editions – were the most influential between 1500 and 1849, and compares these to what is represented in accounts of the history of economic thought today. The most interesting outcome of this work is that if we assume some degree of correlation between the influence of a text and the number of editions published, the publication history we present here suggests that some authors who were once influential are now being neglected.

ARQUIVO: Hierarquia de Necessidades: Nain vs Marlow (2013)

Nessa época eu estava interessado em achar uma nova forma de representar a demanda por bens, sem usar as elasticidades.

This article gives reasons as to why Maslow’s & ERG Theory of Needs is inaccurate. It also gives reasons why the same is inaccurate in an organizational perspective. The author also gives a alternative model of needs, namely the Nain Model, which is particularly applicable in an organizational perspective. This article has been written for those interested in Organizational Behaviour.

ARQUIVO: O que sabemos sobre organização das firmas (2013)

Artigo interessante e antigo do vox sobre caixas pretas, ambiente determinando design (evolução ou ECD?), focado em política de comérico externo.

Increasingly, people are pointing the finger of blame for economic woe at large firms. This column argues that organisation design is often affected by government trade policy. If firm organisation design has implications for consumer welfare in terms of prices and quality of product, evidence suggests that governments should make sure that in future, trade policy and corporate governance policy are more complementary.

ARQUIVO: Pensando com open data (2012)

MENSAGEM: Compartilhem o seu código!

Accessing the data is a key part of verifiability of scientific results, but it isn’t enough. Scientists have the burden of convincing a skeptical audience they have done everything possible to root error out of their research, and so they need to explain (and justify) the steps from data collection to final results. This is nothing new, as reproducibility has been part of the scientific method since the 1660’s, but now the reproducible research movement advocates the sharing the computer code as well as the data that generated the results in the published article.
