Chaos and order in exchange rates
International Journal of Monetary Economics and Finance, 2009This paper asks what accounts for differing levels of exchange rate variance among countries over time. It suggests that the type of political system (i.e., number of policy veto players) is a determinant of policy outcomes in foreign exchange markets. If exchange rate decisions are made by larger groups of actors, we are more likely to witness greater

Magnetic ordered structures by indirect exchange in metallic overlayers
Physical Review B, 1992We investigate the role of the two-dimensional Ruderman-Kittel-Kasuya-Yosida interaction in determining the ordered structure of a magnetic metallic overlayer. It is found that, under suitable conditions, a noncollinear ordered state may be stable at low temperatures, even when the direct exchange interaction prevails. This effect should be relevant to

The Heisenberg ferromagnet with higher-order exchange
Journal of Physics C: Solid State Physics, 1979The authors investigate the properties of ferromagnetic spin systems with higher-order exchange interactions, in particular with four-spin terms of the form (Si.Sj)(Sk.Sl) and (Si.Sj)(Sj.Sk). Using the Green function equation of motion method, and simple decoupling approximations, they obtain renormalised spin-wave energies, magnetisation curves, and ...

Exchange symmetry of magnetically ordered crystals
Soviet Journal of Low Temperature Physics, 1980We present a phenomenological method which makes it possible, in the framework of the exchange approximation, to find the possible microscopic spin-density distribution compatible with a given lattice space group in the magnetically ordered state. All the possible magnetic structures (homogeneous and helical) are found and classified according to ...

Equity order flow and exchange rate dynamics
Journal of Empirical Finance, 2012Abstract This paper contributes to the literature on international portfolio choice in several ways. First, I generalize the model of Dunne et al. (2010) and derive order flow as the result of correlated belief changes by heterogeneous investors. This strategy delivers testable implications for the daily dynamics of stock flows, equity returns, and ...

Architecture and Wilderness: An Exchange of Order
2019If wilderness refers to those spaces that are unoccupied by humans while architecture is one major way that humans occupy space, the terms seem to be mutually exclusive. However, this thesis argues that wilderness and architecture have a fundamental similarity: they are both ways that humans understand and relate to the world.

Stochastic ordering of risk/insurance exchanges
Scandinavian Actuarial Journal, 1980Abstract Insurance contracts employ various devices for sharing risk between the insured and insurer. This paper provides a Stochastic ordering of the risk exchange devices commonly found in direct insurance contracts thereby extending the work of Borch, Arrow and Raviv.
