Ambiguity Aversion, Portfolio Choice, and Life Expectancy

International Economic Review, EarlyView.
ABSTRACT This paper studies how wealth and aging affect portfolio choices in a life‐cycle model with ambiguity aversion. Ambiguity aversion implies wealthier and older agents are endogenously more optimistic about risky asset returns, relative to poorer/younger agents. As life expectancy grows, old agents become even more optimistic, while young agents

Navigating Prediabetes in a Foreign Country: A Qualitative Study of Self‐Management Experiences Among Chinese‐Speaking Immigrants in Australia

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim Chinese‐speaking immigrants in Australia have a higher risk of type 2 diabetes and face more barriers to accessing quality healthcare compared to non‐culturally and linguistically diverse populations. This study aimed to explore the self‐management experiences of Chinese‐speaking Australians with self‐reported lived experience of ...

Research Direction and Science Evaluation: The Role of Coherence and Alignment

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT The decisions of funding agencies greatly influence the direction of scientific research; however, our understanding of how applicants' research directions affect the selection process remains limited. In this study, we investigate how a project's coherence with a scientist's previous work and its alignment with current scientific trends ...

The two-term Abel's integral equation

Journal of Mathematical Extension, 2012
Summary: We investigate the two-term Abel's integral equations. We do this in two different ways and show that such equation is reducible to an integro-differential equation of Volterra type.

Institutional Investor Attention

The Journal of Finance, EarlyView.
ABSTRACT Using data on Internet news reading, we measure fund‐level attention to both aggregate and firm‐specific news and relate it to fund portfolio allocation decisions. In the time series, we find that funds shift attention toward macroeconomic news during periods of high aggregate volatility.

Limiting behavior of quasilinear wave equations with fractional-type dissipation

Advanced Nonlinear Studies
In this work, we investigate a class of quasilinear wave equations of Westervelt type with, in general, nonlocal-in-time dissipation. They arise as models of nonlinear sound propagation through complex media with anomalous diffusion of Gurtin–Pipkin type.

Model Ambiguity versus Model Misspecification in Dynamic Portfolio Choice

The Journal of Finance, EarlyView.
ABSTRACT We study aversion to model ambiguity and misspecification in dynamic portfolio choice. Risk‐averse investors (relative risk aversion γ>1$\gamma > 1$) fear return persistence, while risk‐tolerant investors (0<γ<1$0<\gamma <1$) fear mean reversion, when confronting model misspecification concerns of identically and independently distributed (IID)
