Summary: In this article, we will review very useful packages in the R library which allow downloading the data from the World Development Indicators (WDI) of the World Bank. After that, we will execute some simple tools to create a nice graph of correlations and some basic descriptive statistics. Let’s say we want to use …
Whether if welfare is affected by inequality or growth is one of the “hot” topics in economics. It is stated from economic theory that Welfare can be affected in two potential ways by these situations. A positive effect over Welfare from economic growth, and a negative effect of Welfare by increases in inequality. Some new …

In classic econometrics textbooks and classes, we often associate endogeneity to the correlation or relationship with the error term from a regressor. This is correct and fully agreed upon across authors and professors. But there’s some kind of new endogenous behavior that may not be correlated with the error/residual only, and it may be a …
In modern times, there has been an integration of the technologies of information and the public sector, which are strictly correlated with the development of open government policies across the world. This is an increasing concern in empirical approximations from the field of Public Economics, in the sense that we can ask several questions regarding …

Some of the most popular models used in Data Analysis imply the use of the so-called “Black Box” approach. Regarding the simplest interpretation one can give in this context, it depends on the inputs and outputs that a certain model can deliver in terms of prediction power. If econometrics is thought to estimate population parameters, …
Whether if we’re working with Time Series Data or Panel Data, most of the times we want to follow the analysis of the long-run behavior and the short-run dynamics. An interesting but well-known model that enable us for such approach is the Auto-Regressive Distributed Lag model which stands as ARDL. There are a lot of …

In this article, we will follow Woolridge (2002) procedure to estimate a set of equations with nonlinear functional forms for panel data using the two-stage least squares estimator. It has to be mentioned that this topic is quite uncommon and not used a lot in applied econometrics, this is due that instrumenting the nonlinear terms …
In this article, we will follow Drukker (2003) procedure to derive the first-order serial correlation test proposed by Jeff Wooldridge (2002) for panel data. It has to be mentioned that this test is considered a robust test, since works with lesser assumptions on the behavior of the heterogeneous individual effects. We start with the linear …
