Information and participation in a social program

Participation in a social program, like that in clubs and other social organizations, is the result of a process in which an agent first learns about the requirements, benefits, and the likelihood of acceptance, applies for membership, and finally is accepted or rejected. At each stage of the process, decisions made by the agent are responsive to expectations about the decisions and outcomes at the following stages. We propose a model of the participation process and estimate it using data from a social program in Mexico. We are able to distinguish empirically between information costs and other application costs, and show that self-selection due to information costs in fact contributes to targeting the program to the poorest families.Program participation, take up, information aquisition, targeting, undercoverage, leakage

Policy Platforms, Campaign Spending and Voter Participation

We model electoral competition between two parties in a winner-take-all election. Parties choose strategically first their platforms and then their campaign spending under aggregate uncertainty about voters' preferences. We use the model to examine why campaign spending in the United States has increased at the same time that politics has become more polarized. We find that the popular explanation ­ better targeting of campaign spending ­ is not a likely explanation. While better targeting does lead to greater spending, it leads to less polarization. Instead we argue that the likely explanation is that voters references have become more volatile. This will both raise campaign spending and increase polarization. At the same time it is consistent with the observation that voters have become less committed to the two parties.Non Voting Paradox, Electoral Plataforms, Turnout

Voting Leaders and Voting Participation

We model electoral competition between two parties in a winner take all election. Parties choose strategically first their platforms and then their campain spending under aggregate uncertainty about voters' preferences. In the unique Nash equilibrium larger elections are characterized by a higher participation rate. Moreover, no matter what the voters' preferences are, parties spend exactly the same amounts for their campain in equilibrium. Platforms converge to the center (median voter) and spending increases as the uncertainty over voters' preferences decreases.Voter's Paradox, Aggregate Uncertainty.
