Replication material for "Searching for the Cartel Party: Inter-Party Collusion and Legislative Activity" as presented at EPSA 2018.
The code turns legislative cosponsorship data into a panel dataset of political parties nested into country-specific parliamentary chambers. Some parties are observed at several points throughout the period under examination. Some aspects of the panel data related to party-specific cosponsorship behaviour are then modelled via (one-part) fractional response regression models.
The working paper and conference slides are available from the authors on email request.
Details on the data can be found in DATA.md.
Initially written in R 3.3.3 in strict mode. Currently being updated for R 4.1.0.
