supported the project that led to this and the earlier volume, Federalism and Social Policy. Theresa Ramirez and Connie Rockman supported that project with the generosity and competence they always show. Comments from Alan Trench, Janet Laible, and Margitta Mätzke on the initial development of this project were very helpful. Finally, the University of Michigan Press, especially Elizabeth Demers, Kevin Rennells, and Haley Winkle, were the combination of supportive, engaged, tough, and patient that authors always appreciate.
CHAPTER 1Why Should We Care about Federalism?In Texarkana there is an unusual building. As its name suggests, the town straddles the border between the U.S. states of Texas and Arkansas. The building stands along the border, half on each side. It is a U.S. federal government building, finished in 1933, that combines post offices and courts. The federal courts serving Texas are on the Texas side, and the federal courts serving Arkansas are on the Arkansas side. A post office, equally divided between the two states, serves both. The street splits to go around the building, with different pavement quality and parking rules on the two sides.That one building in a little-known railroad town is a metaphor for federalism. The states constitute the environment, but the federation constitutes the states. It is a legacy of specific political moments and policy decisions that there is a shared post office, serving the American people, in a unifying federal building that reinforces juridical divides between states in its very design. Perhaps it is telling that it is said (by the town's tourism bureau) to be the second most photographed federal building in the United States. It is of no significant architectural interest-except insofar as its location and its twinned courthouses inscribe federal politics in its stones. Letters mailed there since 1933 have been postmarked with a stamp that marks them as having been mailed in both states: "Texarkana-AR-TX" or "Texarkana, USA."The concrete complexity of a federal building in the American Cotton Belt belies much of what is written about federalism. Much research about the impact of federalism, or any other political or social institution, treats it as a binary variable, present or absent, and then look for its effects. Endless effort has been expended and endless ink spilled in scholarly and popular 1. More specifically, this book focuses primarily on federal countries located in Australasia, North America, and Western Europe, which does not mean the lessons it draws are not applicable to federal countries located outside the Global North, such as Argentina,
