A non-deterministic uncertainty and global sensitivity analysis, based on the Sobol’s method, is developed for a parabolic-trough direct steam generation plant for process heat applications. The objective of this work is to evaluate the robustness of the simulation-based design stage, identifying major modelling sources of uncertainty, as well as quantifying and ranking the relevance of its con...

We develop new measures of time-varying risk aversion and economic uncertainty that can be calculated from observable financial information at high frequencies. Our approach has four important elements. First, we formulate a dynamic no-arbitrage asset pricing model that consistently prices all assets under assumptions regarding the joint dynamics among asset-specific cash flow dynamics, macroec...
