1. data (ORBIS)
Flat files: 750 Gb in ~50 files
- Entities: Sector, addresses, type of entity. 200m, 10y.
- Financial: Revenue, employees, assets, profit, taxation, etc
- Ownership: Direct/Total ownership relationships
- Directors: Name, nationality, age, gender
- Positions: Type of position, company and director
Cleaning steps
- Entities: Delete branches and foreign companies
- Financial: De-consolidation (avoid double counting)
- Positions: Keep important positions and de-duplication
- Quantify the unknown: https://arxiv.org/abs/1612.01510
Tools: http://github.com/uvacorpnet
- Gephi (network visualization)
- Inkscape (improve visualizations)
- Python (cleaning and analysis)

4. projects involving ofcs
4.1 UNCOVERING OfC
``Uncovering Offshore Financial Centers: Conduits and Sinks in the Global Corporate Ownership Network''
https://www.nature.com/articles/s41598-017-06322-9
Characterize OFCs
- sinks:
- UK territories / former colonies
- LU, HK
- conduits:
- NL / UK / IE / CH / SG

4.5 detecting money flows indirectly
FDI is great, but what happens to the money
Who competes at country level?
5. last thoughts
- New databases with increasing quality are becoming available
- New analyses are possible:
- Other units of analysis (firm, city, region)
- Other methods (network analysis, machine learning)
- New challenges associated to large size:
- Data management
- Data quality:
- Non-uniform data quality
- Manual exploration is not possible
- Statistics:
- Most regressions will find some effect
- Corrections, e.g. train/split
- Others:
- Require interdisciplinary teams
- Communication is hard
