We examine the profitability and welfare implications of price discrimination in a multi-dimensional model. First, when firms price discriminate on one and the same dimension, uniform price lies in between discriminatory prices and price discrimination raises profits relative to uniform pricing....

Although high productivity growth is a primary economic goal across nations, it can lead to short run adjustment problems when it temporarily achieves high levels. This may induce a jobless recovery when labor productivity is high while an economy is experiencing sluggish growth or a recession....

We have studied the superconductivity of Pb ultra-thin films with thickness from 1 monolayer (ML) to 7 ML grown on Si(111) by molecular beam epitaxy. In situ low temperature scanning tunneling spectroscopy (STS) and angle-resolved photoemission spectroscopy (ARPES) measurements were performed on...

An agent-based model is developed that matches the results of <xref ref-type="bibr" rid="AAQ033C28">Xia and Sexton (2004)</xref> as well as our generalization of their model. We relax Xia and Sexton's assumption of no supply response by captive feeders, which reduces the price-depressing effect of captive supplies. Finally, the agent-based...

Previous theoretical work has compared a private-value auction and posted-price market, and an affiliated-value auction and a posted-price market to determine the selling method preferred by sellers. Much less, however, is known about the seller’s preferred selling method when the buyers have...

In this work, a new fully discrete stabilized finite element method is studied for the two-dimensional transient Stokes equations. This method is to use the difference between a consistent mass matrix and underintegrated mass matrix as the complement for the pressure. The spatial discretization...

Producers can make their market timing decisions either based on fundamental or technical analysis to reach specific financial target. A generalized mixture model is used to discriminate producers into more than one segment according to their marketing strategies. The heterogeneous selling...

Iterated function system (IFS) models have been explored to represent discrete sequences where the attractor of an IFS is self-affine either in R2 or R3 (R is the set of real numbers). In this paper, the self-affine IFS model is extended from R3 to Rn (n is an integer and greater than 3), which...
