In this blog post we discuss a number of financial terms whose precise meaning is frequently intentionally or unintentionally obscured. As a result those terms may, like a Rorschach Blot, mean different things to different people. Unlike this famous psychological test, ambiguity in weighty financial matters can have adverse consequences.

Summer is underway and for the Google Summer of Code 2021 season Open Risk is happy to join forces with the Hydra Ecosystem to mentor student projects
exploring next generation API's. The project aims to guide students to build a hypermedia enabled REST
service around standardized credit portfolio data. More specifically the
project will build a REST service as backend for a hypothetical banking
entity that collects and disseminates credit portfolio data conforming
to an established public standard (the EBA NPL templates).
You can read more about the motivation, objectives and check the status of the project in the usual place.
In this second Open Risk White Paper on Connecting the Dots we
examine various measures of concentration, diversity, inequality and sparsity in
the context of economic systems represented as network (graph)
We adopt a stylized description of economies as property
graphs and illustrate how relevant concepts can represented in this
language. We explore in some detail data types representing economic
network data and their statistical nature which is critical in their use
in concentration analysis.
We proceed to recast various known indexes drawn from distinct disciplines in a unified computational context.
Graphs have a variety of distinct uses in data science. In this blog post we review various important graph types and sketch their linkages and relationships. The review provides an operational guide towards a better overall understanding of those powerful tools and potential uses in risk management
