Loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that the first-order-different utility impact of wealth gains and losses leads loss-averse investors to behave similarly to investors with high risk...

Currency investors exhibit a tendency to cut risk by pairing both longs and shorts following losses and a weaker tendency to add risk following gains. By differentiating between position level, portfolio level and aggregate cross-portfolio losses in currency investments we demonstrate that this...

It is well established that international portfolios are far substantially under-diversified, contrary to predictions of traditional finance theory. Even after controlling for market segmentation and “investability” of foreign markets, portfolio under-diversification remains a puzzle. I...

We study the asset allocation of an investor with prospect theory (PT) preferences. First, we solve analytically the two-asset problem of the PT investor for one risk-free and one risky asset and find that loss aversion and the reference return affect differently less ambitious investors and...

Loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that the different utility impact of wealth gains and losses leads loss-averse investors to behave similarly to investors with high risk aversion. But if...

This research addresses whether geographic diversification provides benefits over industry diversification. In the absence of constraints, no empirical evidence is found to support the argument that country diversification is superior. With short-selling constraints, however, the geographic...

This paper addresses the question of optimal currency exposure for a risk-and-ambiguity-avers international investor. A robust mean-variance model with smooth ambiguity preferences is used to derive the optimal currency exposure. In the theoretical part, we show that the sample-efficient...

"Sustainable investment"-includes a variety of asset classes selected while caring for the causes of environmental, social, and governance (ESG). It is an investment strategy that seeks to combine social and/ or environmental benefits with financial returns, thus linking investor’s social,...

The European Union wants to foster the sustainable growth of the economy by using the financial markets as an intermediary. Thus, politicians need to know which factors account for differences in socially responsible investments (SRI) between countries to create an efficient framework, which...
