We consider an infinite graphene geometry where bonds and sites have been removed selectively to map it onto an effective Sierpinski gasket comprised of hexagons. We show that such a structure is capable of sustaining an infinite number of extended single particle states inspite of the absence...

The paper takes as its objective context the growing disparity in the distribution of Foreign Direct Investment (FDI) among the developing nations. While FDI in the developing world has grown fairly rapidly since the late 1980s, a disaggregated analysis demonstrates a considerable imbalance at...

We refute a recent claim in the literature [Czech. J. Phys. <Emphasis Type="Bold">56, 1191 (2006)] of a “new" quantum deformation of GL(2). Copyright EDP Sciences/Società Italiana di Fisica/Springer-Verlag 2007

We developed a complete self-consistent TB-LMTO-Augmented space recursion (ASR) method for calculating configurational average properties of substitutionally disordered binary alloys. We applied our method to fcc based Cu-Ni, Ag-Pd for different concentrations of constituent elements and...

This paper examines whether employment and wages in the US manufacturing sector exhibit any long-run relationship with import competition. The results based on a multivariate panel cointegration analysis of observations on 12 two-digit SIC manufacturing industries over the period from the third...

We construct a generalized model of finite change whereby exogenous shocks such as international trade or technological change, not only contract, but totally shut down production in some sectors. In such cases even in a competitive structure and in absolute contrast to the conventional wisdom,...

We build up a Ricardian trade model for a small open economy with imperfection in the market for credit which eventually affects the pattern of production and trade. Workers/entrepreneurs are endowed with different levels “capital” and need to borrow to produce the credit intensive good....

We build up a simple Ricardian trade model with imperfection in the market for credit which affects the pattern of production. Workers/entrepreneurs are endowed with different levels “capital†and need to borrow to produce the credit intensive good. We argue that in such a framework...

A vast and growing empirical literature aims at identifying key determinants of sovereign default. The literature is extensive and controversial. Can policy-makers use this body of research to learn anything that can help reduce the likelihood of sovereign default? We use a variant of Extreme...

We visit the role of privatization in the location decision of firms in an industry where no firm can produce all varieties demanded. We demonstrate that the Nash equilibrium locations are socially optimal, in the presence of a publicly owned firm, notwithstanding the degree of privatization.
