We propose a new game theoretic approach to modeling large elections that overcomes the “paradox of voting” in a costly voting framework, without reliance on the assumption of ad hoc preferences for voting. The key innovation that we propose is the adoption of a “smooth” policy rule under which the degree to which parties favor their own interests is increasing in their margin of victory. In other words, mandates matter. We argue that this approach is an improvement over the existing literature as it is consistent with the empirical evidence. Incorporating this policy rule into a costly voting model with paternalistic voters yields a parsimonious model with attractive properties. Specifically, the model predicts that when the size of the electorate grows without bound, limiting turnout is...

Segregation has been a recurring social concern throughout human history. While much progress has been made to our understanding of the mechanisms driving segregation, work to date has ignored the role played by location-specific amenities. Nonetheless, policy remedies for reducing group inequity often involve place-based investments in minority communities. In this paper, we introduce an exogenous location-specific public good into a model of group segregation. We characterize the equilibria of the model and derive the comparative statics of improvements to the local public goods. We show that the dynamics of neighborhood tipping depend on the levels of public goods. We also show that investments in low-public good communities can actually increase segregation.

The Tiebout model assumes that individuals 'vote with their feet' and choose to locate in the jurisdiction which best matches their fiscal preferences. In this paper, we test Tiebout's voting mechanism by examining whether housing purchase decisions are sensitive to changes in local property tax rates. Results from previous empirical tests of the link between property taxes and mobility are mixed and typically suffer from a myriad of identification problems including the confounding influence of tax rates on public good levels, tax endogeneity arising as a result of jurisdictional composition, and aggregation bias. In this paper, we are able to overcome many of the traditional obstacles to identification by: 1) focusing on purchasers of vacation homes who arguably receive no benefits from ...

This paper uses confidential Census data, specifically the 1990 and 2000 Census Long Form data, to study the demographic processes underlying the gentrification of low-income urban neighborhoods during the 1990's. In contrast to previous studies, the analysis is conducted at the more refined census-tract level with a narrower definition of gentrification and more closely matched comparison neighborhoods. The analysis is also richly disaggregated by demographic characteristic, uncovering differential patterns by race, education, age and family structure that would not have emerged in the more aggregate analysis in previous studies. The results provide no evidence of displacement of low-income non-white households in gentrifying neighborhoods. The bulk of the increase in average family i...
