This publication presents a methodology for planning sustainable supply chain initiatives, consisting of three scopes, each with its appropriate mechanism and background theory. The first one 'Acting In' structures organizational practices in a 'Framework for Managing Sustainable Supply Chain...

Classical contributions in international macroeconomics rely on goods-market mechanisms to reconcile the cyclicality of real exchange rates when financial markets are incomplete. However, cross-border trade in one domestic and one foreign-currency-denominated risk-free asset prohibits these...

This paper describes the international flow of funds associated with calm and volatile global equity markets. During calm periods, portfolio investment by real money and leveraged investors in advanced countries flows into emerging markets. When central banks in the receiving countries resist...

This paper considers two alternative formulations of the linear factor model (LFM) with nontraded factors. The first formulation is the traditional LFM, where the estimation of risk premia and alphas is performed by means of a cross-sectional regression of average returns on betas. The second...

Reliable estimates of variances and covariances are crucial for portfolio management and risk controlling. This paper investigates alternative methods to estimate time varying variance-covariance matrices: ordinary estimates and exponentially weighted moving averages in comparison to Markov...

The hypothesis of the paper that the European money demand function is more stable than the money demand function of any single European country is based on the well known portfolio diversification principle. Econometric estimates of country specific and European money demand functions confirm...

Portfolio choice is usually modelled by von Neumann-Morgenstern utility. Risk-value models are more general and permit the derivation of risk-value efficient frontiers. A behaviorally based risk measure with an endogenous or exogenous benchmark is used to derive efficient portfolios and to...

The current discussion about stability of the European money demand function is flawed by a confusion of two different concepts of stability (adjustment speed versus error variance). The meaning and importance of the underlying notions of stability is clarified. It is demonstrated that necessary...
