"Implications of Broader Sampling Strategy in the Contest of the Special Safeguard Mechanism" by Verma, Monika, Paul Preckel, Thomas Hertel and Will Martin Abstract This paper explores the sensitivity of model statistics to breadth of sampling used under the Sensitivity Analysis – a method very often used for General Equilibrium models and an inbuilt tool in General Equilibrium Modeling Package (GEMPACK). We force the Stroud and Liu Gaussian Quadratures available in Systematic Sensitivity Analysis (SSA) in GEMPACK to sample from beyond their usual √2SD and 1SD limits. The breadth of sampling domain could be an important aspect for models that are highly non-linear and where results depend on thresholds and regime switches. In the Special Safeguards (SSM) example used here, we find that the broader sampling technique gives us very different results for second tier tariffs on wheat imports. |
