On the small sample properties of weak exogeneity tests in cointegrated VAR models
Brüggemann, Ralf - 2002
We investigate the small sample properties of two types of weak exogeneity tests in cointegrated VAR models that are frequently used in applied work. The first one is the standard Likelihood Ratio (LR) test in the Johansen framework. The second test is based on mapping the cointegrated VAR model...

The local power of some unit root tests for panel data
Breitung, Jörg - 1999
(1993) and Im, Pesaran and Shin (1997) suggest bias adjusted t-statistics. Such corrections are necessary to account for the … affected by two different terms. The first term represents the asymptotic effect on the bias due the detrending method and the … do not require a bias correction. The results of a Monte Carlo experiment suggest that avoiding the bias can improve the …

Measurement error, biases, and the validation of complex models
Carroll, Raymond J.; Galindo, Christian D. - 1997
There are three major points to this article: 1. Measurement error causes biases in regression fits. The line one would obtain if one could accurately measure exposure to environmental lead media will differ in important ways when one measures exposure with error. 2. The effects of measurement...

Analyzing multigroup data with structural equation models
Görz, Nicole; Hildebrandt, Lutz; Annacker, Dirk - 2000
In empirical applications of structural equation modeling researchers often assume that the sample under investigation is homogenous unless observed characteristics allow for a division of the sample into mutual exclusive homogenous subgroups. If such information is not available, unobserved...

The determinants of health care expenditure : testing pooling restrictions in small samples
Herwartz, Helmut; Theilen, Bernd - 2000
Healthcare expenditure has increased substantially in all western industrialized countries in the last decades. The necessity to contain the increase in health care expenditure has motivated the Analysis of its determinants to explain differences across countries and health systems. However,...

Quantile hedging
Föllmer, Hans; Leukert, Peter - 1998
In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling...

On model based seasonal adjustment procedures
Breitung, Jörg - 1998
In this note the unobserved component approach underlying the software package SEATS is compared with the Beveridge-Nelson type of decomposition for seasonal time series. The main strength of the SEATS approach lies in the appealing model formulation and the careful specification and adjustment...

The monetary model of the exchange rate : a structural interpretation
Moersch, Mathias; Nautz, Dieter - 1998
We emphasize the importance of properly identifying the long-run relations underlying the monetary model of the exchange rate. The separate estimation of long-run money demands leads to a "structural" error correction equation which allows an interpretation of the various channels affecting the...
