This paper lays the mathematical foundations of the notion of an investment's sustainability return and investigates three different models of portfolio selection with probabilistic constraints for safety first investors caring about the financial and the sustainability consequences of their...

Purpose – The purpose of this paper is to analyze the main motives of investors in allocating their money in a socially responsible (SR) way. Design/methodology/approach – The paper is based on primary data collected in a survey using an online questionnaire. This paper applies tests for...

This paper presents a model of the complete microcredit financing chain investor - MIV - MFI - micro-borrower, in which social-minded MIVs provide funds only to those MFIs which do not exploit their bargaining power towards micro-borrowers. The MFIs with the highest bargaining power do not use...

This article examines the determinants of the optimal percentage that private investors seek to invest in a socially responsible (SR) way when forming their portfolio. By conducting a global online survey in English, German and French, we find indications that it is sufficient for the majority...

While the academic world is still discussing if charting works or if it is more or less something like "Voodoo finance", the practical orientated world has been using technical analysis for decades. One argument of practitioners is, that technical analysis is useful to "disciplinate" the trader...

We provide evidence of the exogenous impact of environmental and social performance components on credit ratings in North America, Europe, and Asia. In particular, the product innovation dimension is clearly identified as being the dominating driver of credit ratings within the environmental...

We investigate the asset pricing implications of the greenness of bonds. To estimate a green-pricing effect, we determine the 'green bond premium' as the difference between the yields of matched conventional and green-labeled bonds. On a cross-sectional average, green bonds experience a...

We extend risk-value models for valuing streams of risky cash flows by establishing the well-known concept of terminal value in this context. For a constant growth assumption we are able to derive upper and lower bounds for the terminal value in the case of a translation-invariant and in the...
