We propose and demonstrate a simple method for guiding researchers in developing quantitative models of economic fluctuations. We show that a large class of models are equivalent to a prototype growth model with time-varying wedges that resemble time-varying productivity, labor taxes, and capital income taxes. We use data to measure these wedges, called efficiency, labor, and investment wedges,...

In this proceedings a particular example from [KMPY] is presented: the construction of the level 2 Fock space of Uq(ŝl2). The generating ideal of the wedge relations is given and the wedge space defined. Normal ordering of wedges is defined in terms of the energy function. Normally ordered wedges form a base of the wedge space. The q-deformed Fock space is defined as the space of semi-infinite ...

The nonphysical wedge is a modality that uses computer-controlled jaw motion to generate wedge-shaped dose distributions. There are Varian enhanced dynamic wedges (EDWs) and Siemens virtual wedges (VWs). We recently commissioned dynamic wedges on both Varian and Siemens LINACs. The beam data, acquired with a Wellhofer chamber array and a Sun Nuclear profiler, are used for modeling in the ADAC P...

The resistance of shallow foundations to lateral loads is often relied upon to transmit the base shear forces from the ground to a building during an earthquake. Considering the importance of this link in the lateral load path it receives little attention in current design practice in New Zealand. An assumption is commonly made, either explicitly or implicitly, that the combination of sliding f...

In this paper, symmetric water entry of twin wedges is investigated for deadrise angle of 30 degree. Three numerical simulation of a symmetric impact, considering rigid body dynamic equations of motion in two-phase flow is presented. The two-phase flow around the wedges is solved by Finite Element based on Finite Volume method (FEM-FVM) which is used in conjunction with Volume of Fluid (VOF) sc...

Fundamental to any theory of capital taxation is a description of individual savings behavior. Successful descriptions of savings behavior have often resorted to the habit formation hypothesis. This paper studies the effect of habit formation on optimal capital taxes in a dynamic Mirrleesian model. We make three distinct contributions. First, we decompose intertemporal wedges (implicit capital ...

This study aimed to understand how systematic changes in arch height and two designs of heel wedging affect soft tissues under the foot. Soft tissue thickness under the heel and navicular was measured using ultrasound. Heel pad thickness was measured when subjects were standing on a flat surface and standing on an orthosis with 4 and 8 degree extrinsic wedges and 4 mm and 8 mm intrinsic wedges ...
