Treated politicians, treated voters: A natural experiment on political budget cycles

Abstract

Although pre-electoral political manipulation of the budget — the political budget cycle (PBC) — has been long investigated by scholars, empirical findings are mixed at best. This is partly because of the non-random nature of election timing. There also exist ongoing debates over how the budget is manipulated for electoral purposes. We address these issues by exploiting a natural experiment in Japan, where the timing of both executive and legislative elections in municipalities is fixed, staggered, and as good as random, and by using the detailed items of the municipal budget. We find that total and capital expenditures follow the PBC, but tax revenue does not. We also find that executive elections are associated with the PBC, but legislative elections are not. Against the conventional wisdom that democratic or developed countries are free from the PBC, our case of Japan offers an intriguing exception.
