The paper presents and tests Dynamic Value at Risk (VaR) estimation procedures for equity index returns. Volatility clustering and leptokurtosis are well-documented characteristics of such time series. An ARMA (1, 1)-GARCH (1, 1) ap- proach models the inherent autocorrelation and dynamic...

The paper studies a factor GARCH model and develops test procedures which can be used to test the number of factors needed to model the conditional heteroskedasticity in the considered time series vector. Assuming normally distributed errors the parameters of the model can be straightforwardly...

This paper explores the sensitivity of plug-in based subset tests to instrument exclusion in linear IV regression. Recently, identification-robust statistics based on plug-in principle have been developed for testing hypotheses specified on subsets of the structural parameters. However, their...

The classical case of comparative advantage is put into a new formal framework, that is, the behavioral axioms of standard economics are replaced by a set of structural axioms. This enables a comprehensive analysis that takes the effects on income and profit explicitly into account. The axioms...

We introduce the sequential equal surplus division for sharing the total welfare resulting form the cooperation of agents along a river with a delta. This allocation rule can be seen as a generalization of the contribution vectors introduced by Ju, Borm and Ruys (2007) in the context of...

Many questions have been raised as to whether financial accounting has become more conservative. The value relevance and qualitative characteristics of accounting information have become topics of particular relevance given the role they have assumed in influencing the value judgment of...

We develop a general method to solve models of interactions between multiple agents, including the possibility of strategic advantage for some of them. We argue that this type of model applies to the description of apparently irrational or biased behaviors in a person whose action is the...
