The life-cycle theory of consumption draws a well-established distinction between the implications for consumption of changes in wealth perceived to be of a “transitory” as opposed to a “permanent” nature. In this paper, using a unique combination of regulatory and survey micro-data, we examine the importance of the life-cycle theory, in estimating housing wealth effects for the Irish mortgage ...

Cr and Mn monolayers on a triangular lattice are prototypical examples of frustrated spin systems in two dimensions. Collinear and noncollinear magnetic structures of these monolayers on Cu~111! substrate are investigated on the basis of first-principles total-energy calculations using the full-potential linearized augmented plane-wave method extended by the vector spin-density description for ...

The grandmasters were Michael Rohde, Patrick Wolff, Boris Gulko, Joel Benjamin, Ilya Gurevich, and Alexander Ivanov. The computers included two commerciallyavailable dedicated units and four PC programs. The dedicated units were ChessSystem R30 by TASC B.V. (operated by Chris Avery) and Renaissance SPARC by Saitek Industries Ltd. (operated by Andrew Metrick), and the PC programs were Kasparov's...

The unoccupied electronic states of the Si~111!-Au(532) system have been studied, using inverse photoemission. Striking similarities exist between the unoccupied bands of the Si~111!-Au(532) system and the Si~111!-(737) and Si~111!-Au(A33A3)R30° systems. We argue that these similarities suggest that the Si~111!-Au(532) system contains Si adatoms, and that the adatom-induced surface states domin...

Using reflection high-energy electron diffraction (RHEED), the growth onset of molecular beam epitaxy (MBE) deposited germanium telluride (GeTe) film on Si(111)-(√3 × √3)R30°-Sb surfaces is investigated, and a larger than expected in-plane lattice spacing is observed during the deposition of the first two molecular layers. High-resolution transmission electron microscopy (HRTEM) confirms that t...

This paper investigates whether the principle of minimum differentiation extends to the location choices of multi-product firms of different sizes supplying differentiated goods to consumers with heterogeneous tastes. Our analysis explicitly allows for the possibility that the resulting location equilibria will be asymmetric, and we compare the multiproduct equilibria with the location configur...

In this paper, we sought to extend the theory of the location determinants of MNEs by challenging one of the fundamental assumptions underlying it, namely that location advantages are absolutes whose values are identical for different MNEs. We explicitly acknowledge the relative value of location advantages for individual MNEs and search for the firm-specific attributes affecting this variation...

We consider a Hotelling game where a finite number of retailers choose a location, given that their potential consumers are distributed on a network. Retailers do not compete on price but only on location, therefore each consumer shops at the closest store. We show that when the number of retailers is large enough, the game admits a pure Nash equilibrium and we construct it. We then compare the...

A structure model for the Ge(111)-(4×4)-Ag surface is proposed. The model was derived by applying direct methods to surface X-ray diffraction data. It is a missing top layer reconstruction with six Ag atoms placed on Ge substitutional sites in one triangular subunit of the surface unit cell. A ring-like assembly containing nine Ge atoms is found in the other triangular subunit. The stability of...

Surface chemistry involved in the epitaxy of graphene by sublimating Si atoms from the surface of epitaxial 3C-SiC(111) thin films on Si(111) has been studied. The change in the surface composition during graphene epitaxy is monitored by in situ temperature-programmed desorption spectroscopy using deuterium as a probe (D(2)-TPD) and complementarily by ex situ Raman and C1s core-level spectrosco...
