The CORPNET research group uncovers, investigates and aims to understand global networks of corporate power in contemporary global capitalism
What are we doing?
How?
- Using "big data" and bringing new methods from complex systems
- For the analysis of corporate ownership and corporate elites
Data collection
- Macro-data: e.g. Country indicators
- Micro-data: Surveys
- Linear regression
- By hand in Excel
"standard" social science framework
Data wrangling
Data
analysis
Theoretical understanding --> Hypothesis --> Test
(2) Modeling data-missingness
(6) Non-linear modeling
(4) Machine learning:
- Database merging
- Data classification
computational social science framework
Data collection
(1) New methods to collect data: Data scraping
Data wrangling
Data
analysis
(3) Set up appropriate data structures
(7) Motif-detection
(5) Description (data viz)
Data --> Patterns/Hypothesis --> (Generative mechanisms) --> Theory embedding

(7) Non-linear modeling
- Ising model to understand information spread across the network of interlocks (w/ Rick Quax)
- Higher-order markov chains to understand combinations of countries that are important
- SBM to predict the tax rate using corporate networks (w/ Leto Peel)
...however this is our weaker part. Most of our research is descriptive.
