The performance of the pivotal-voter model in small-scale elections

"How well does the pivotal-voter model explain voter participation in small-scale elections? This paper explores this question using data from Texas liquor referenda. It first structurally estimates the parameters of a pivotal-voter model using the Texas data. It then uses the estimates to evaluate both the within and out-of-sample performance of the model. The analysis shows that the model is capable of predicting turnout in the data fairly well, but tends, on average, to predict closer electoral outcomes than are observed in the data. This difficulty allows the pivotal-voter model to be outperformed by a simple alternative model based on the idea of expressive voting"--National Bureau of Economic Research web site.
