A Note on Factor Prices and Technical Progress

Factor bias , sector bias , and the effects of technical progress on relative factor prices *

The effects of technical progress on relative factor prices in the two-country, two-good, two-factor Heckscher-Ohlin model are investigated. Technical progress is classified according to factor-augmenting bias, factor-using bias, and sector bias. A complete set of relations between technical progress parameters and relative factor prices, depending on the elasticities of substitution in demand ...

Supermarket Promotions and Food Prices: A Note

Using a sample comprising nearly 250,000 weekly prices from the largest seven UK supermarket chains, this note investigates two pricing practices that have attracted public interest: the tendency for promotions to ‘disguise’ rises in non-sale prices and the inflation of prices prior to sales which ‘exaggerate’ the discount. Analysing price dynamics before and after periods of promotional discou...

Technical note on the paper :

In Section 3.1 of [1] a methodology is presented to compute the salient points of a 3D mesh based on the computation of its protrusion function, see Equation (1) in [1]. Explicitly each point υ of the Mesh is examined as a potential salient point. Specifically a geodesic neighborhood is constructed for each point of the mesh and it is considered as a salient point if it is the local maximum of ...

An Investigation on the Causes of a Rotor Bending and its Thermal Straightening (TECHNICAL NOTE)

Distortion or bend in a turbine rotor (especially HIP rotors) may be caused by a number of factors, either singularly or in combination. In general, the causes of rotor bend can be classified invariably in two categories: Rapidly forming permanent rotor bends and/or Slower forming rotor bends, which could trip the turbines’ emergency stop. One of the major modifying solutions for rapid repairin...
