A two‐period, career‐concerns model with symmetric information but uncertainty about each worker’s ability is analyzed. Contracts are unobservable, but incomes are observable. It is shown that effort is distorted upward by contracts being unobservable and that the distortion depends positively on turnover.

This study develops estimates of expected loss severities on mortgage exposures using data from Florida during the Great Recession. This paper marks the first attempt at addressing sample selectivity in the context of loss models. We also construct measures of home equity that are more accurate than those employed in previous studies. We find that failing to address sample selection and the use of noisy equity measures in loss models can bias loss estimates significantly. We also find significantly higher loss severities and a greater sensitivity of loss severity to equity than what previous studies report.

This paper presents a new approach to the measurement of the effects of spatial mismatch that takes advantage of matched employeremployee administrative data integrated with a person-specific job accessibility measure, as well as demographic and neighborhood characteristics. We focus on a group of job searchers for plausibly exogenous reasons: lower-income workers with strong labor force attachment separated during a mass layoff. Our results support the spatial mismatch hypothesis. We find that better job accessibility significantly decreases the duration of joblessness among lower-income displaced workers, especially for blacks, women, and older workers.
