PPP: a Disaggregated View
Fischer, Christoph - 2004
By disaggregating price indices, it becomes apparent that the real exchange rate consists of the real exchange rate for a single good and a weighted sum of relative prices between goods. When applying a battery of panel unit root tests to this sum and its components, it is found that both the...

Concepts to Calculate Equilibrium Exchange Rates: An Overview
MacDonald, Ronald - 2000
In this paper we present a critical overview of differnt methods of constructing an equilibrium exchange rate. The recent literature on purchasing power parity (PPP) indicates that on its own PPP is not a good vehicle for defining an equilibrium exchange rate. Rather, we argue that the latter...

The behaviour of the real exchange rate: evidence from regression quantiles
Nikolaou, Kleopatra - 2006
We test for mean reversion in real exchange rates using a recently developed unit root test for non-normal processes based on quantile autoregression inference in semi-parametric and non-parametric settings. The quantile regression approach allows us to directly capture the impact of different...

Why not use standard panel unit root test for testing PPP
Lyhagen, Johan - 2000
In this paper we show the consequences of applying a panel unit root test when testing for a purchasing power parity relationship. The distribution of the tests investigated, including the IPS test of Im et al (1997), are influenced by a common stochastic trend which is usually not accounted...

A note on testing for purchasing power parity
Heinen, Florian - 2011
We examine the asymptotic behavior of unit root tests against nonlinear alternatives of the exponential smooth transition type if the data is erroneously nonlinearly transformed. We show analytically and by a Monte Carlo study that the probability of rejecting the correct null of a random walk...

Subjective unemployment expectations and (self-) insurance
Hartmann, Ida Maria; Leth-Petersen, Søren - 2023
We study how individual unemployment expectations are shaped and updated using a unique longitudinal survey data set with subjective unemployment expectations. The survey data is linked with third-party reported administrative data on unemployment realizations, such that we are able to examine...

Home bias in global bond and equity markets: the role of real exchange rate volatility
Fidora, Michael; Fratzscher, Marcel; Thimann, Christian - 2006
This paper focuses on the role of real exchange rate volatility as a driver of portfolio home bias, and in particular as an explanation for differences in home bias across financial assets. We present a Markowitz-type portfolio selection model in which real exchange rate volatility induces a...

Quantifying risk and uncertainty in macroeconomic forecasts
Knüppel, Malte; Tödter, Karl-Heinz - 2007
This paper discusses methods to quantify risk and uncertainty in macroeconomic forecasts. Both, parametric and non … macroeconometric model of the Bundesbank for Germany. Forecast intervals that integrate judgement on risk and uncertainty are obtained. …

The Provision of Local Public Services in a Risky Environment: An Application to Crime
Traub, Stefan - 2006
We state efficiency conditions for the provision of congestable local public goods that diminish individual-specific proprietary risks. The optimum level of such a public service is determined by equating the sum of the reductions of the expected property losses due to a better service level...

Risk, delegation, and project scope
Roider, Andreas - 2007
exogenous risk and delegation. That is, we show that only if exogenous risk is sufficiently large, the risk-neutral principal … may prefer to delegate authority over decisions to the risk-averse agent. Intuitively, for incentive reasons, the … principal may optimally want to allow the agent to reduce his risk exposure. Nevertheless, even endogenous risk may be higher …
