International investment positions and exchange rate dynamics : a dynamic panel analysis
In this paper we revisit medium- to long-run exchange rate determination, focusing on the role of international investment positions. To do so, we develop a new econometric framework accounting for conditional long-run homogeneity in heterogeneous dynamic panel data models. In particular, in our model the long-run relationship between effective exchange rates and domestic as well as weighted foreign prices is a homogeneous function of a country’s international investment position. We find rather strong support for purchasing power parity in environments of limited negative net foreign asset to GDP positions, but not outside such environments. We thus argue that the purchasing power parity hypothesis holds conditionally, but not unconditionally, and that international investment positions are an essential component to characterizing this conditionality. Finally, we adduce evidence that whether deterioration of a country’s net foreign asset to GDP position leads to a depreciation of that country’s effective exchange rate depends on its rate of inflation relative to the rate of inflation abroad as well as its exposure to global shocks.

International Investment Positions and Exchange Rate Dynamics
We revisit medium- to long-run exchange rate determination, focusing on the
role of international investment positions. To do so, we make use of a new
econometric framework accounting for conditional long-run homogeneity in
heterogeneous dynamic panel data models. In particular, in our model the long-
run relationship between effective exchange rates and domestic as well as
weighted foreign prices is a homogeneous function of a country's international
investment position. We find rather strong support for purchasing power parity
in environments of limited negative net foreign asset to GDP positions;
furthermore, long-run exchange rate equilibria may have little relation to
purchasing power parity outside such environments. We thus argue that the
purchasing power parity hypothesis holds conditionally, but not
unconditionally, and that international investment positions are an essential
component to characterizing this conditionality
a Conditional GVAR Approach
We examine the effects of increased international integration of both goods
and financial markets on business cycle dynamics. To do so, we develop a new
econometric framework for modelling cross-country spillovers in which the
magnitude of these spillovers is an empirically determined function of the
degree of a country's integration with international goods and financial
markets. Our results suggest that the magnitude of cross-country spillovers
for most country pairs has been increasing with strengthened goods and
financial markets integration
Static and Dynamic Critical Behavior of a Symmetrical Binary Fluid: A Computer Simulation
A symmetrical binary, A+B Lennard-Jones mixture is studied by a combination
of semi-grandcanonical Monte Carlo (SGMC) and Molecular Dynamics (MD) methods
near a liquid-liquid critical temperature . Choosing equal chemical
potentials for the two species, the SGMC switches identities () to generate well-equilibrated configurations of the system on
the coexistence curve for and at the critical concentration, ,
for . A finite-size scaling analysis of the concentration susceptibility
above and of the order parameter below is performed, varying the
number of particles from N=400 to 12800. The data are fully compatible with the
expected critical exponents of the three-dimensional Ising universality class.
The equilibrium configurations from the SGMC runs are used as initial states
for microcanonical MD runs, from which transport coefficients are extracted.
Self-diffusion coefficients are obtained from the Einstein relation, while the
interdiffusion coefficient and the shear viscosity are estimated from
Green-Kubo expressions. As expected, the self-diffusion constant does not
display a detectable critical anomaly. With appropriate finite-size scaling
analysis, we show that the simulation data for the shear viscosity and the
mutual diffusion constant are quite consistent both with the theoretically
predicted behavior, including the critical exponents and amplitudes, and with
the most accurate experimental evidence.Comment: 35 pages, 13 figure
