The increasing trends of integrated and concentrated broiler production results in a serious threat to environment through excessive litter production and lack of its proper disposal. Production concentration in limited area is a major source of surface as well as ground water pollution....

In this work, we begin with an investigation into the temporal correlation in default risk. We first establish a link between the dynamics of house price changes and the dynamics of default rates in the Gaussian copula framework by specifying a time series model for a common risk factor. We show...

We explore the properties of a Stein-like shrinkage estimator that combines the fully correlated and uncorrelated Random Parameters Logit model(RPLM). Monte Carlo experiments show that shrinkage and pretest estimators can improve upon the fully correlated RPLM estimator.
