Efficient estimators of cointegrating vectors are presented for systems involving deterministic components and variables of differing, higher orders of integration. The estimators are computed using GLS or OLS, and Wald Statistics constructed from these estimators have asymptotic x2 distributions

A new approach is presented for elastic registration of medical images, and is applied to magnetic resonance images of the brain. Experimental results demonstrate remarkably high accuracy in superposition of images from different subjects, thus enabling very precise localization of morphological

The paper presents empirical evidence based on the U.S. Consumer Expenditure Survey that accounting for limited asset market participation is important for estimating the elasticity of intertemporal substitution. Differences in estimates of the EIS between asset holders and non–asset holders

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly

The multi-layer beam consisted of materials with extremely different elastic properties, such as silicon and Polydimethylsiloxane (PDMS), has many important applications. The Kirchhoff assumption that the straight lines normal to the midsurface remain normal after deformation does not hold any

This paper shows experiments using a unique method of implementing a structured free surface boundary for a finite-difference model. The method employs the same concepts as the implicit solutions used for finite-difference formulations posed in a recursive manner. The displacements required across

considered methods (PCA, Bayesian Intra/extrapersonal Classifier and Elastic Bunch Graph Matching) on FERET tests which include testing the robustness of the method against different facial expressions, lighting and aging of the subjects. In addition to its efficiency, the simplicity of the proposed method

. In the general non-linear income tax problem, this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of Mirrlees. The optimal non-linear tax rate formulas are expressed in terms of elasticities

; and such fluctuations, along with the impact of wars, yield historical paths of growth which differ from those which the optima, calculated before the event, would have yielded. Nevertheless, the economic history of growing societies takes a part of its rude shape from the effort of societies to approximate the optimum

Abstract. We consider a curvature model for bilayer vesicles with an area-difference elasticity or non-local bending-energy term. Such a model in-terpolates between the bilayer-couple and spontaneous-curvature models. We report preliminary results for the budding transition. The shape
