Open Data

Exploring Brazilian data in a map

This is another work by Gerson. He made all the codes this time, and I just wrote these few words here. Again, this is part of our project to foster Open Science in our research community and make coding more accessible.

A highchart of GDP growth

Gerson and I are working in several projects to foster Open Science in our research community. We are sharing in this post a code to create a map using open data from the World Bank.

Fama and French - Part 1

This post is co-authored with Gerson Junior. The goal The goal of this post is simple: to learn how to calculate the Fama and French portfolios' returns. Keep in mind that we begin from scratch, so we are not thinking about coding optmization for now.

Global Index of Peace

Did you know there is a Global Index of Peace? I certainly didn’t. Apparently, the Institute for Economics & Peace measures peace in almost all countries since 2014. Brazil is not doing well in this ranking.

Google trends and finance

Disclosure: I apologize in advance for the errors when using Latin accents in the text below! Someone asked me if Brazilians are studying more finance and investments, or only those that already know about investments are investing in stocks these days.

Economic Freedom of Brazil

I read this article here that made me think about the Economic Freedom of Brazil. The article discusses the increase in Economic Freedom over the last few years. After reading the article, I needed a better perspective over a longer period.

Brazilian corruption Index (WGI)

There is one dataset that I like a lot: the Worldwide Governance Indicators (WGI) project. It contains data since 1996 about the governance of all countries. Governance here is measured by the six following variables:

Ibovespa vs. Ibovespa in dollar

I was wondering how to download data from Ipeadata to use in research. So let’s use this post to learn how to create a graph with data from ipeadata. Start by installing and loading the following package.

Some words about Open Science (OS)

In the past few years, the research in management (but also in other fields) is facing what is called a reproducibility crisis, as several researchers tried to replicate published studies but fail.

The number of Brazilian listed firms

Let’s use this quick post to learn how to create a graph using the World Bank data. Start by installing and loading the following packages. library(wbstats) library(ggplot2) Then, download the data.

Brazil Economic Policy Uncertainty

In this post, I will show how to create a graph about the Brazilian Economic Policy Uncertainty index. For more information about this index, click here. Shortly, it is an index that calculates economic policy uncertainty by searching for specific words in Brazilian newspapers.

My very first post!

Welcome! I am happy that you are here! This is truly the first post on my website. In the past few days, I made some posts to practice dealing with the website code.
