Table A.7 tests this. I measure turnover as a cross-bloc handover between appointment and delivery. The report is appointed under one bloc and delivered under the other. This is fixed before any implementation, so it does not depend on how long a provision takes to enact. I then regress full enactment on a distributive indicator and its interaction with the cross-bloc handover, with commission fixed effects. The coefficient on the interaction between the distributive indicator and the cross-bloc handover measures how much more distributive provisions are trimmed when there was a handover, compared to when there was not. The cross-bloc indicator is the same for every provision in a report. Its own effect is therefore absorbed by the fixed effects, and only the interaction is identified. The interaction is not statistically significant. The trim is no larger for reports that change hands between blocs during the commission's work. The point estimate leans slightly more negative under a handover, but I cannot reject equality, and the test is underpowered. The trim thus looks like a structural regularity rather than an artifact of which bloc inherits the report.
I think this whole thing is a bit too long. ALso, Table A7 should reflect the symmetry of 5.3., i.e. both dimensions. So should table a7 do. Agreed?
