A reappraisal of the evidence on PPP: a systematic investigation into MA roots in panel unit root tests and their implications

Fischer, Christoph; Porath, Daniel - 2006

Panel unit root tests of real exchange rates - as opposed to univariate tests - usually reject non-stationarity. These tests, however, could be biased if the real exchange rate contained MA roots. Indeed, two independent arguments claim that the real exchange rate, being a sum of a stationary...

A note on the coefficient of determination in regression models with infinite-variance variables

Loretan, Michael Stanislaus; Kurz-Kim, Jeong-Ryeol - 2007

Since Mandelbrot's seminal work (1963), alpha-stable distributions with infinite variance have been regarded as a more realistic distributional assumption than the normal distribution for some economic variables, especially financial data. After providing a brief survey of theoretical results on...

Systemic bank risk in Brazil: an assessment of correlated market, credit, sovereign and inter-bank risk in an environment with stochastic volatilities and correlations

Barnhill, Theodore M.; Souto, Marcos Rietti - 2008

In this study we develop and demonstrate a powerful and flexible forward-looking portfolio simulation methodology for assessing the correlated impacts of market risk, and private sector, sovereign and inter-bank default risk on both individual banks (i.e. 28 of the largest Brazilian banks) and...

A comparative study of monotone nonparametric kernel estimates

Pilz, Kay F.; Dette, Holger - 2004

In this paper we present a detailed numerical comparison of three monotone nonparametric kernel regression estimates, which isotonize a nonparametric curve estimator. The first estimate is the classical smoothed isotone estimate of Brunk (1958). The second method has recently been proposed by...

Genetic algorithms: a tool for optimization in econometrics - basic concept and an example for empirical applications

Doherr, Thorsten; Czarnitzki, Dirk - 2002

This paper discusses a tool for optimization of econometric models based on genetic algorithms. First, we briefly describe the concept of this optimization technique. Then, we explain the design of a specifically developed algorithm and apply it to a difficult econometric problem, the...

Simulated Classical Tests in the Multiperiod Multinomial Probit Model

Ziegler, Andreas - 2002

This paper compares different versions of the simulated counterparts of the Wald test, the score test, and the likelihood ratio test in the multiperiod multinomial probit model. Monte Carlo experiments show that the simple form of the simulated likelihood ratio test delivers the most favorable...

Dahle, Claudia; Sureth, Caren - 2008

In this paper we analyze the impact of various minimum taxation concepts on corporate investment decisions. These investments can be realized in the form of either a real or a financial investment. In a quantitative analysis we refer to the future values of the investments as an indicator of...

Size distortions of tests of the null hypothesis of stationarity: Evidence and implications for applied work

Caner, Mehmet; Kilian, Lutz - 1999

It is common in applied econometrics to test the null hypothesis of a level-stationary process against the alternative of a unit root process. We show that the use of conventional asymptotic critical values for the stationarity tests of Kwiatkowski et al. (1992) and Leybourne and McCabe (1994)...
