Das Papier untersucht die durch eine Europäische Währungsunion zu erwartenden Änderungen der Geldschöpfungsgewinne der Mitgliedsländer. Dazu werden die zwischen 1980 und 1995 erzielten einzelstaatlichen Geldschöpfungsgewinne nach dem monetären und dem Opportunitätskostenkonzept...

In seinem Heft 13/2004 vom 26.3.2004 veröffentlichte das Deutsche Ärzteblatt einen Artikel mit dem Titel "Von der Wahrscheinlichkeit des Irrtums", in dem der Autor Wolfgang Weihe eine seiner Meinung nach sowohl neue als auch ungewöhnliche Position bezüglich der Interpretation von...

We show that tests for a break in the persistence of a time series in the classical I(0) - I(1) framework have serious size distortions when the actual data generating process exhibits long-range dependencies. We prove that the limiting distribution of a CUSUM of squares based test depends on...

In this article we provide evidence for a rational bubble in S\&P 500 stock prices by applying a test for changing persistence under fractional integration proposed by Sibbertsen and Kruse (2007). We find strong evidence for stationary long memory before the estimated change point in 1955 and a...

We show that the CUSUM-squared based test for a change in persistence by Leybourne et al. (2007) is not robust against shifts in the mean. A mean shift leads to serious size distortions. Therefore, adjusted critical values are needed when it is known that the data generating process has a mean...

We have developed a new test against spurious long memory based on the invariance of long memory parameter to aggregation. By using the local Whittle estimator, the statistic takes the supremum among combinations of paired aggregated series. Simulations show that the test performs good in finite...

We develop a Wald type test to distinguish between long memory and ESTAR nonlinearity by using a directed-Wald statistic to overcome the problem of restricted parameters under the alternative. The test is derived from two basic model specifications where the first is the standard model based on...

Evidence from credit files is provided to examine bank lending determinants of Thai commercial banks. Their lending practice follows reasonable patterns as a standard set of variables, including indirect risk variables, explains much of the variance in interest rate spread. Reflecting...

Financial liberalisation has often failed in the past due to underestimated problems of structural change. We analyse such changes in lending behaviour of Thai commercial banks during a liberalisation phase by way of unique micro data. Liberalisation has expected positive effects, such as...
