Social optimization problems are often used in economics to study important issues. In a social optimization problem, the sum of individual weighted utilities is maximized over all feasible allocations that satisfy certain constraints. In this paper, we provide a mechanism that determines the...

What degree of tax autonomy should be granted to a regional government on a local tax base? Although the regional policy maker aims at maximizing social welfare, her tax policy may be distorted by the lobbying activity of local taxpayers. In this political environment we characterize the...

This paper studies a production economy with aggregate uncertainty where consumers have limited commitment on their financial liabilities. Markets are endogenously incomplete due to the fact that the borrowing constraints are determined endogenously. We first show that, if competitive financial...

We consider the Hotelling-Downs model with n = 2 oce seeking candidates and runo voting. We show that Nash equilibria in pure strategies always exist and that there are typically multiple equilibria, both convergent (all candidates are located at the median) and divergent (candidates locate at...

The number of automobile recalls in the U.S. has substantially increased over the last two decades, and after a record of over 30 million cars recalled in 2004, in the last few years it has consistently reached between 15 and 17 million, and in 2009 alone 16.4 million cars were recalled....

A pervasive concern with the use of self-reported health and disability measures in behavioral models is that they are biased and endogenous. A commonly suggested explanation is that survey respondents exaggerate the severity of health problems and incidence of disabilities in order to...

The paper presents an experiment showing that some of the results in Benjamin, Dougan and Buschena (2001) (BDB hereafter) should be attributed to an anchoring effect. More precisely, it appears that, when asked to evaluate successively the number of deaths per lethal risks for two different...

This paper uses the first three waves of the Health and Retirement Survey (HRS) to investigate the determinants of labor force status among older Americans. Using transitions at two-year intervals we find that after being retired or unemployed, those who are actively searching for a job have a...
