Significant advances have now occurred in the theoretical and in the empirical knowledge-base of researchers studying problems in natural resource and environmental economics. This has been accompanied by the utilization of many and varied research tools. These developments notwithstanding,...

This paper proposes a generalized exponential moving average (EMA) model, a new stochastic volatility model with time-varying expected return in financial markets. In particular, we effectively apply a particle filter (PF) to sequential estimation of states and parameters in a state space...

We study the correct estimation of the true variance of the predictor in stochastic Kriging (SK). First, we obtain macroreplications for a SK metamodel that approximates a single-server simulation model; these macroreplications give independently and identically distributed predictions. This...
