Das vorliegende Dissertationsprojekt hatte zwei zentrale Schwerpunkte. Den ersten Schwerpunkt bildete die innovative Insolvenzprognosemodellierung für ukrainische Unternehmen.Dafür wurde im Wesentlichen die moderne internationale Standardmethodik zur Insolvenzprognose auf Basis der...

In many scientific studies, the response variable bears a generalized nonlinear regression relationship with a certain covariate of interest, which may, however, be confounded by other covariates with unknown functional form. We propose a new class of models, the partly parametric generalized...

This dissertation studies the question of nonlinearities in the Phillips curve relationshipin France, Germany and Italy. The implications from the theoretical models are that themechanisms that make the Phillips curve nonlinear can work through different channels.Therefore, this thesis not just...

The field of nonlinear regression is a long way from reaching a consensus. Once a method decides to explore nonlinear combinations of predictors, a number of questions are raised, such as what nonlinear combinations to permit and how best to search the resulting model space. Genetic Association...

An avalanche of articles has described the testing of a time series for the presence of unit roots. However, economic model builders have disagreed on the value of testing and how best to operationalise the tests. Sometimes the characterization of the series is an end in itself. More often, unit...

We study the behavior of real exchange rates in a two-country dynamic equilibrium model. In this model, consumers can only consume domestic goods but can invest costlessly in capital stocks of both countries. Nevertheless, transporting goods between the two countries is costly and, hence, the...

Using long-span data on the dollar-sterling and dollar-franc real exchange rates over the past two centuries, we apply the findings of various strands of the recent literature in order to examine the statistical and economic significance of the Harrod-Balassa-Samuelson effect (the effect of...

This paper examines the long-run validity of purchasing power parity (PPP) for fourteen developing countries. The period examined is 1973:4 through 2002:8. The methods of Elliot, Rothemberg and Stock (1996), Kwiattkowski et al. (1992) and Geweke and Porter-Hudak (1983) are employed to detect the...

Finding evidence of the theoretical relationship between exchange rate and inflation has been a difficult proposition in an exchange rate market, despite many studies in developed markets. Three recent papers employing a new research design, Theil’s Divisia index method, found that this...

This Study addressed the inflation accountingproblem with respect to Greece. This problem had been unaddressed despite the serious implications it may have on micro- and macro-decision making due to the high andpersistent inflation Greece has sustained from 1973 and afterwards.To accomplish the...
