The importance of risk management increases as farmers become more exposed to risk. But risk management is a difficult … topic because income risk is the result of the complex interaction of multiple risk factors combined with the effect of an … increasing array of possible risk management tools. In this paper we use Bayesian networks as an integrated modelling approach …

Motivated by the construction of the Itô stochastic integral, we consider a step function method to discretize and simulate volatility modulated Lévy semistationary processes. Moreover, we assess the accuracy of the method with a particular focus on integrating kernels with a singularity at...

First, we propose a more e¢ cient implementation of the Smolyak method for inter- polation, namely, we show how to avoid costly evaluations of repeated basis functions in the conventional Smolyak formula. Second, we extend the Smolyak method to include anisotropic constructions; this allows us...

The theoretical literature on generational risk assumes that this risk is large and that the government can effectively … effectively banishes the dimensionality curse in models like ours. We find that intrinsic generational risk is quite small, that … government policies can produce generational risk, and that bond markets can help share generational risk. We also show that a …

We develop numerically stable and accurate stochastic simulation approaches for solving dynamic economic models. First, instead of standard least-squares methods, we examine a variety of alternatives, including least-squares methods using singular value decomposition and Tikhonov regularization,...

Stochastic simulation with antithetic variates is used to evaluate the bias of deterministic simulation in nonlinear econometric models. Application to the Klein-Goldberger model exemplifies the potentiality of the method.
