We provide the first systematic study of liquidity in the foreign exchange market. We find significant variation in liquidity across exchange rates, substantial illiquidity costs, and strong commonality in liquidity across currencies and with equity and bo ...
In an estimated two-country DSGE model, we find that efficiency shocks specific to investment account for more than half of the forecast variance of cyclical fluctuations in the US trade balance. Both domestic and foreign investment-specific shocks have a ...
Ghent University Faculty of Economics and Business Administration Working Paper 2008/5442011
This thesis consists of three chapters. The first chapter endogenizes technological change by introducing a stylized innovation process driven by a R&D–dependent Poisson process in a Cox, Ingersoll and Ross (1985) production economy. The model reproduces s ...
We present an approach to multi‐stage international portfolio optimization based on the imposition of a linear structure on the recourse decisions. Multiperiod decision problems are traditionally formulated as stochastic programs. Scenario tree based solut ...
We use several popular tests to test the validity of the Purchasing Power Parity (PPP) hypothesis. In particular, we analyze four classes of tests-standard univariate unit root tests, co-integration, panel unit root tests, and unit root tests for nonlinear ...
This paper presents an equilibrium model in a pure exchange economy when investors have three possible sources of heterogeneity. Investors may differ in their beliefs, in their level of risk aversion, and in their time preference rate. The authors study th ...
We investigate how various treatments of exact exchange affect defect charge transition levels and band edges in hybrid functional schemes for a variety of systems. We distinguish the effects of long-range vs short-range exchange and of local vs nonlocal e ...
The hydrogen tracer diffusion in LiBH4 has been determined by spatially resolved Raman spectroscopy. The measurements give direct evidence of a macroscopic diffusion of BH-4 ions as well as atomic exchange of hydrogen between the anions. An effective trace ...
We study whether monetary policy should target the exchange rate in a two-country model with non-atomistic wage setters, non-traded goods and different degrees of exchange- rate pass through. Commitment to an exchange rate target reduces the labor market d ...
Due to the important direct and indirect costs of the intervention, more detailed examination methods based on data as obtained from monitoring is suggested. This paper reports on an ongoing study to examine the fatigue safety of one standard bridge type, ...
