Partisan Conflict in the U.S. and Potential Impacts on the Economy.

As someone interested in measuring disagreement inpolitical decision-making and then understanding itsmacroeconomic implications, I developed the PartisanConflict Index (PCI) in my 2018 paper "Partisan Conflictand Private Investment." But as economists, no matter its origins, we mustgauge the level of policy disagreements, place them incontext and, critically, try to better understand theimplications for the economy. We will also concentrate attention here on theU.S. given its economic importance and because data andanalyses are available to draw upon, even though our aimremains more general: to connect legislative disagreementto economic outcomes and policies in any major economy.
