Using data from a Canadian field experiment designed to elicit risk and time preferences and quantify financial barriers to higher education, we estimate the distribution of the value of financial aid for prospective students, and relate it to parental socio-economic background, individual skills, risk and time preferences. Our results point to credit(More)
<lb>This dissertation consists of three essays on the structural analysis of spatial inequalities. The first two<lb>essays rely on estimated parameters while the third is a fully calibrated model. In the first essay, we<lb>investigate the magnitude of individual willingness to pay for housing and neighborhood attributes by<lb>estimating a dynamic hedonic(More)
We build an equilibrium job search model, where workers engage in both offand on-the-job search over a set of cities, to quantify the impact of spatial matching frictions and mobility costs on the job search process. Migration decisions, based on a dynamic utility trade-off between locations, can rationalize diverse wage dynamics as part of forward-looking(More)
We build a dynamic model of migration where, in addition to classical mobility costs, workers face informational frictions that decrease their ability to compete for distant job opportunities. We structurally estimate the model on a matched employer-employee panel dataset describing labor market transitions within and between the 100 largest French cities.(More)
This paper proposes a unified framework for the analysis of inequalities. In contrast to the former literature on inequalities, housing is included as a major determinant of individual saving behavior. Disparities across locations affect individual outcomes in both labor and education markets. In a Bewley-Huggett-Aiyagari type model where several frictions(More)
In Conakry the maternal mortality rate in the University Hospital is not the real maternal mortality rate of the country but it gives an idea of the importance of this problem of public health. The authors try to explain the reasons for this high mortality and propose preventive measures: increase in primary health care, equipping of regional obstetric(More)
Using a unique field experiment from Canada, we estimate individual preference over risk and time and show considerable heterogeneity in both dimensions and relatively stable distributions across our various specifications, which include hyperbolic, quasi-hyperbolic discounting as well as subjective failure probability over future payments. We investigate(More)
We study the properties of spatial equilibrium in an economy where locations have heterogeneous endowments and the labour market is subject to matching frictions. Both workers and firms make endogenous location decisions, which, in turn, determine the spatial distribution of unemployment, wage and firm density, as well as city population. We explain why(More)
In a two-sided market with private contracting, what are the costs and benefits of spatial concentration? The oil and natural gas leasing market facilitates studying the net effect of two countervailing forces. First, firms benefit from signing contracts associated with large, contiguous acreage as it allows them to apply for a permit to drill a well and(More)
