Der Internationalisierungsprozess im Einzelhandel lässt sich in den meistenLändern Europas an einer ähnlich verlaufenden Entwicklung - dem Ausbaugroßflächiger, nach funktionalen Gesichtspunkten angelegter Versorgungszentrenan den Stadträndern - ablesen. Die nationalen Strukturen in der...

The well-known absence-of-arbitrage condition NFLVR from the fundamentaltheorem of asset pricing splits into two conditions, called NA and NUPBR.We give a literature overview of several equivalent reformulations of NUPBR;these include existence of a growth-optimal portfolio, existence of the...

This paper proposes several new tests for structural change in themultivariate linear regression model. One of the most popular alternatives are Sup-Wald type tests along the lines of Bai, Lumsdaine and Stock (1998), which Bernard,Idoudi, Khalaf and Yélou (2007) show to have very large size...

This paper extends the cross sectionally augmented panel unit root test proposed byPesaran (2007) to the case of a multifactor error structure. The basic idea is to exploitinformation regarding the unobserved factors that are shared by other time series in additionto the variable under...

This paper may be understood as a continuation of Topsøe’s seminal paper ([16]) to characterize, within an abstract setting, compact subsets of finite inner regular measures w.r.t. the weak topology. The new aspect is that neither assumptions on compactness of the inner approximating lattices...

This paper considers the implications of the permanent/transitory decomposition of shocksfor identification of structural models in the general case where the model might contain morethan one permanent structural shock. It provides a simple and intuitive generalization of theinfluential work of...
