Cointegrating smooth transition regressions with applications to the Asian currency crisis

Saikkonen, Pentti; Choi, In - 2000

This paper studies the smooth transition regression model where regressors are I(1) and errors are I(0). The regressors and errors are assumed to be dependent both serially and contemporaneously. Using the triangular array asymptotics, the nonlinear least squares estimator is shown to be...

Lag selection in subset VAR models with an application to a US monetary system

Brüggemann, Ralf; Lütkepohl, Helmut - 2000

Alternative modeling strategies for specifying subset VAR models are considered. It is shown that under certain conditions a testing procedure based on t-ratios is equivalent to sequentially eliminating lags that lead to the largest improvement in a prespecified model selection criterion. A...

The empirical determinants of the Euro : short and long run perspectives

Chinn, Menzie David - 2000

The behavior of the dollar/euro exchange rate is modeled using a monetary model of the exchange rate. The econometric … analysis is complicated by the short sample span of actual euro data available for analysis. Hence, data on a "synthetic" euro …, is identified for the 1991M08-1999M12 period using the Johansen procedure. The model implies that the euro was …

Modeling the interdependence of volatility and inter-transaction duration processes

Grammig, Joachim; Wellner, Marc - 1999

-transaction duration process and vice versa. In order to solve the estimation problems implied by this interdependent formulation, we first … propose a GMM estimation procedure for the Autoregressive Conditional Duration model. The method is then extended to the … simultaneous estimation of the interdependent duration-volatility model. In an empirical application we utilize the model for an …

Credit contagion and aggregate losses

Giesecke, Kay; Weber, Stefan - 2002

Credit contagion refers to the propagation of economic distress from one firm or sovereign government to another. In this paper we model credit contagion phenomena and study the fluctuation of aggregate credit losses on large portfolios of financial positions. The joint dynamics of firms' credit...

The monetary model of the exchange rate : a structural interpretation

Moersch, Mathias; Nautz, Dieter - 1998

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...

Volatility estimates of the short term interest rate with an application to German data

Dankenbring, Henning - 1998

This paper proposes a procedure for testing alternative specifications of the short term interest rate's dynamics which takes into account that according to some restrictions the interest rate is nonstationary, i.e. the traditional test statistic has a non-standard distribution. Moreover, we do...
