A general formulation of Mixed Proportional Hazard models with K random effects is provided. It enables to account for a population stratified at K different levels. We then show how to approximate the partial maximum likelihood estimator using an EM algorithm. In a Monte Carlo study, the...

This article provides evidence about the interrelationships between wages and prices at the microeconomic level. We rely on the right-to manage model to specify and estimate a multivariate model explaining the timing and magnitude of wage changes at the firm level. The modeling of price changes...
