This dataset includes network data for state aid cases. Network data is similar to directed dyad-year data except that it only includes directed dyad-years with at least one infringement case. For every year, there is one node per department and one node per member state. Edges can only exist between a department and a member state. There is an edge between a department and a member state if and only if the department opened at least one case against the member state during that year. The weight of the edge is the number of cases that the department opened against the member state. There is one observation per department per member state per year (1988-2020), excluding directed dyad-years where the state was not a member of the EU, but only if count of cases is positive.

A data frame with 9 variables:
Numeric. An ID number that uniquely identifies each observation in the dataset.
Numeric. The year the case was opened by the Commission.
Numeric. An ID number that uniquely identifies each
Directorate-General (DG) of the Commission. There are three DGs that can
open state aid cases. The DG for Competition (COMP) is coded 1, the

String. The name of the Directorate-General (DG) of the Commission that opened the state aid case.
String. A multi-letter code assigned by the Commission that uniquely identifies each Directorate-General (DG) of the Commission.
Numeric. An ID number that uniquely identifies each member state. This ID number is assigned when member states are sorted by accession date and then alphabetically.
String. The name of the member state that the Commission opened the case against.
String. A two letter code assigned by the Commission that uniquely identifies each member state.
Numeric. A count of the number of cases opened by the Commission at this level of aggregation.
