A vast scholarly literature addresses the question of why voters in certain electoral districts receive larger allocations of discretionary government resources than voters in others. When resource allocations are found to be positively correlated with electoral support for a ruling party across electoral districts, then it is presumed to favor core supporters. When resource allocations are found to be negatively correlated with support for a ruling party across electoral districts, then it is presumed to favor swing voters. The tournament theory offers an alternative explanation for why resource allocations can vary so substantially across electoral districts. When politicians use tournaments between the municipalities in their electoral districts to win elections, then across electoral districts, the size of a district’s resource allocation will be influenced by the relative sizes of municipalities therein. Moreover, this variable – district-level asymmetry – is expected to act on both electoral support and resource allocations: lowering lowers electoral support and increasing resource allocations. This chapter uses a host of regression specifications to test these two hypotheses using data from Japan, 1980–2014. In doing so, it provides an original account for why money is negatively correlated with support across electoral districts in Japan.
