This is my personal playground where I write about things I'm learning or doing.
The Beveridge curve is a valuable tool for analysing labour markets. In this post, I use it to identify trends in the German job market from 2010 to 2023. By utilising the D3.js visualisation library, we can explore how Germany's Beveridge curve evolved over time, providing an intriguing perspective on the country's labour market dynamics.
I have always been an avid user of official statistics. Eurostat, the OECD, the World Bank, other international organisations and national statistics agencies such as the French INSEE are valuable sources of data. In this post, I present a simple and efficient way of interacting with data from these official providers via the SDMX standard using the pandaSDMX Python library.
In this second part, I present a practical example of how to write code for web scraping in a functional programming style. The example illustrates how to use immutable data structures, functions and Python’s @functools.singledispatch decorator to build a resilient data collection pipeline for web scraping.
For a long time, I have associated web scraping projects with a heavy dose of object-oriented programming. Python developers might be familiar with classes of spiders similar to those used in the web scraping framework Scrapy. In this two-part article, I present a way to write code for web scraping in a functional programming style. In this first part, I explain what I mean by that and what kind of advantages I see with that approach.
This is the second part of a project that illustrates the use of quantitative methods for developing a typology of aid donors. We'll use agglomerative, hierarchical clustering and spectral clustering to identify groups of aid donors.
This is the first post in a two-part series about using quantitative methods to develop typologies. The first part deals with Principal Components Analysis; the second will be about Clustering. I use the topic of development cooperation as a practical example.
Special methods do not only power Python’s built-in objects. They can be used to give custom classes the same look and feel. In this post, I illustrate the use of special methods by defining a simple class of polynomials.
