Trade Elasticities [PDF]

open access: possibleReview of International Economics, 2016
AbstractConventional aggregate trade elasticity estimates hardly vary across countries. We introduce an aggregate elasticity that is implied by theory: It is the value that equates the welfare gains from trade as implied by one‐ and multi‐sector versions of the model in Arkolakis et al. (American Economic Review, 102 (2012):94–130). These estimates are

Brain Tissue Elasticity and CSF Elastance

Neurological Research, 1989
In the analysis of the pressure-volume relationship of the intracranial system, the concept of brain elastance, sometimes called tissue elastance or CSF elastance, is often used. It is generally designated as Ecsf and is calculated as the slope of the pressure-volume curve of the system.

Elastic Knots

Physical Review Letters, 2007
We study the mechanical response of elastic rods bent into open knots, focusing on the case of trefoil and cinquefoil topologies. The limit of a weak applied tensile force is studied both analytically and experimentally: the Kirchhoff equations with self-contact are solved by means of matched asymptotic expansions; predictions on both the geometrical ...

Elasticity Optimism [PDF]

open access: possibleSSRN Electronic Journal, 2008
On average, estimates of trade elasticities are smaller in aggregate data than at sector level. This is an artifact of aggregation. Estimations performed on aggregate data constrain sector elasticities to homogeneity, which creates a heterogeneity bias. The paper shows such a bias exists in two prominent approaches used to estimate elasticities, which
