We develop some simple simulation algorithms for CIR and Wishart processes. We investigate rigorously the square of a matrix valued Ornstein–Uhlenbeck process, the main idea being to split the generator and to reduce the problem to the simulation of the square of a matrix valued...

Deep drainage can contribute to groundwater table rises and salinity, and is a complex function of rainfall, land management and soil hydraulic properties. Each of these components is uncertain and variable in space and time. This study quantifies the associated uncertainty using a Monte Carlo...

The aim of this study was to compare production and policy risk of organic, integrated and conventional cropping systems in Norway. Experimental cropping system data (1991-1999) from eastern Norway were combined with budgeted data. Empirical distributions of total farm income for different...

We analyze the effectiveness of monetary policy rules in the presence of the zero lower bound on nominal interest rates, using stochastic simulations. Specifically, we assume a small structural model composed of the IS and AS curves with both forward-looking and backward-looking agents, and...
