The variance of arbitrated wage settlements is significantly lower than the variance of negotiated wage settlements in a sample of teachers' contracts, even when possible selection of contracts into arbitration is accounted for. This result is consistent with the hypothesis that arbitrated settlements do not incorporate all of the information that is reflected in negotiated settlements.

A standard efficient-contracts model of employment determination in a unionized labor market is contrasted with a naive model of labor supply and demand that allows for the possibility of monopsony in the market for public school teachers. The standard model is consistent with the data and suggests that employment contracts are strongly efficient, but a more surprising result is that the simple supply/demand model is not rejected by the data either. Estimates of the latter suggest that the demand for teachers is inelastic and that the supply curve is slightly upward sloping, rather than perfectly elastic, at the union wage.

Expert performance is often evaluated assuming that good experts have good outcomes. We examine expertise in medicine and develop a model that allows for two dimensions of physician performance: decision making and procedural skill. Better procedural skill increases the use of intensive procedures for everyone, while better decision making results in a reallocation of procedures from fewer low-risk to high-risk cases. We show that poor diagnosticians can be identified using administrative data and that improving decision making improves birth outcomes by reducing C-section rates at the bottom of the risk distribution and increasing them at the top of the distribution.

Mortality is a crucial indicator of well-being, and recent mortality trends have been a subject of public debate in many Western countries. This paper compares mortality inequality in Canada and the United States over the period 1990/91 through 2010/11. In Canada, mortality inequality remained constant among the youngest but increased for men over 24 and women over 14. In contrast, in the United States, mortality inequality fell for children and youth and either modestly increased or held steady at older ages. By 2010/11, the initially higher US rates of infant and child mortality had almost converged to their Canadian counterparts.
