A vast amount of empirical and theoretical research on public good games indicates that the threat of punishment can curb free-riding in human groups engaged in joint enterprises. Since punishment is often costly, however, this raises an issue of second-order free-riding: indeed, the sanctioning...

In this article, we study a multi-period multi-product inventory control problem. In the problem, there are N inventory classes which can be substituted for one another to satisfy the demand for a given reservation class (perhaps at a cost). The objective of management is to jointly determine...

Four years of soybean experimental data observed at Daxing, North China Plain, were used to assess the ability of the AquaCrop model to predict soybean final biomass and yield. The model was parameterized and calibrated using field data on leaf area index (LAI), available soil water, soil...

This work derives explicit kernel approximations for universal kriging predictors for a class of intrinsic random function models. This class of predictors is of particular interest because they are equivalent to the standard two-dimensional thin plate smoothing splines. By introducing a...
