1 Mental accounts with horizon and asymmetry preferences
حسابهای ذهنی با ترجیحات افق و نامتقارن-2021
This paper extends mental accounting theory with an investment horizon and asymmetric trade-off between extreme gains and losses. This horizon-asymmetry mental accounting (HAMA) framework widens the spectrum of investors’ optimal portfolio choices considerably. Risk aversion, implied from the mean-variance portfolio theory, and the bond-to-stock ratio decline with the investment horizon. HAMA investors with a large gain–loss asymmetry trade-off are more concerned about skewness and kurtosis rather than variance. To apply the model to United States stock data, we develop a parsimonious semi-parametric version of HAMA that relies on the moments of return distributions. The analysis of optimal portfolios shows that investors who care significantly about upside potential hold asymmetric, leptokurtic, and less diversified allocations.

2 Customer-centric prioritization of process improvement projects
اولویت بندی مشتری محور پروژه های بهبود فرآیند-2020
Today, customers can conveniently compare products and decide how to interact with companies. With customer centricity becoming an important success factor, companies must drive customer satisfaction not only through excellent products but also through customer-centric processes. As many companies face an abundance of action possibilities, fast-changing customer needs, and scarce resources, guidance regarding the customercentric prioritization of process improvement projects is in high need. As existing approaches predominantly focus on process efficiency, we propose a decision model that accounts for the effects of process improvement on customer centricity in line with justificatory knowledge on value-based process decision-making, project portfolio selection, and the measurement of customer satisfaction. When building the decision model, we adopted the design science paradigm and used multi-criteria decision analysis as well as normative analytical modeling as research methods. We evaluated the model by discussing it with practitioners, by building a software prototype, and by applying it at a German insurance company. Overall, our research extends the prescriptive knowledge on process prioritization and customer process management.

4 Investors’ behavior and mutual fund portfolio allocations in Brazil during the global financial crisis
رفتار سرمایه گذاران و تخصیص اوراق بهادار صندوق سرمایه گذاری مشترک در برزیل در طول بحران مالی جهانی-2020
In this paper, I examine the flow and performance of mutual funds in Brazil and their portfolio al- locations during the global financial crisis. First, I show that mutual funds exposed to deposits and securities issued by small banks suffered significant outflows, due to the increased risk aversion following Lehman’s default in 2008. The returns of funds exposed to small banks were also neg- atively affected. Funds adjusted their portfolios by reducing their exposures to deposits of small banks, but they increased risk taking when term deposit coverage limits were raised. The distress among small banks also generated negative spillover to the portfolio management business of banks, reducing their numbers of investors. The results illustrate the potential risks to financial stability, to the extent that interconnections among funds and banks can induce the transmission of shocks across markets.
