Estimation and testing for varying coefficients in additive models with marginal integration
Yang, Lijian; Härdle, Wolfgang; Park, Byeong U. - 2002
We propose marginal integration estimation and testing methods for the coefficients of varying coefficient multivariate … regression model. Asymptotic distribution theory is developed for the estimation method which enjoys the same rate of convergence … as univariate function estimation. For the test statistic, asymptotic normal theory is established. These theoretical …

Semiparametric analysis of German East-West migration intentions : facts and theory
Burda, Michael C.; Härdle, Wolfgang; Müller, Marlene; … - 1997
East-West migration in Germany peaked at the beginning of the 90s although the average wage gap between Eastern and Western Germany continues to average about 25%. We analyze the propensity to migrate using microdata from the German Socioeconomic Panel. Fitting a parametric Generalized Linear...

The Beveridge-Nelson decomposition : a different perspective with new results
Gómez, Víctor; Breitung, Jörg - 1998
We show in the paper that the decomposition proposed by Beveridge and Nelson (1981) for models that are integrated of order one can be generalized to seasonal Arima models by means of a partial fraction decomposition. Two equivalent algorithms are proposed to optimally (in the mean squared...

A note on stochastic volatility, GARCH models, and hyperbolic distributions
Jaschke, Stefan R. - 1997
We establish a relation between stochastic volatility models and the class of generalized hyperbolic distributions. These distributions have been found to fit exceptionally well to the empirical distribution of stock returns. We review the background of hyperbolic distributions and prove...

Finance, investment, and firm value in Germany and the US : a comparative analysis
Nowak, Eric - 1998
Germany and the United States are generally seen as the two competing systems of corporate governance. In search for a comparative welfare analysis of the financial systems, we are interested in (i) the aggregate value-added of corporate investments in the two countries and in (ii) the...

Flexible stochastic volatility structures for high frequency financial data
Feldmann, David; Härdle, Wolfgang; Hafner, Christian M.; … - 1998
Stochastic Volatility (SV) models are widely used in financial applications. To decide whether standard parametric restrictions are justified for a given dataset, a statistical test is required. In this paper, we develop such a test based on the linear state space representation. We provide a...
