Idiosyncratic asset return and wage risk of US households

Economic Inquiry, Volume 63, Issue 2, Page 636-657, April 2025.
Abstract This paper documents the degree of idiosyncratic asset return heterogeneity, serial correlation, and correlation with wage heterogeneity for US households. Novel panel‐data measurements for returns on household assets are proposed. Sizable transitory idiosyncratic return heterogeneity is documented to exist concurrently with permanent ...

Visual Cues Can Alter the Behavioural Responses of Dragonfly Larvae to Chemical Alarm Cues

Ethology, EarlyView.
Using a controlled experimental approach, we examined how chemical and visual cues influence antipredator behaviour in Aeshna cyanea larvae and tested whether risk‐related information can be socially transmitted among nearby conspecifics. Our results show that dragonfly larvae do not copy the antipredator responses of others, but visual cues alter how ...

Closed‐Form Optimal Investment Under Generalized GARCH Models

European Financial Management, EarlyView.
ABSTRACT This paper introduces a new class of stochastic volatility models for asset prices, the generalized Heston Nandi GARCH (GHN‐GARCH), with the primary objective of optimal dynamic asset allocation under expected utility theory for constant relative risk aversion investors. We study some of its theoretical properties, and demonstrate that the GHN‐

Analysis of Sea Turtle Bycatch by Andalusia Pelagic Longline Fleet in the Northeast Atlantic

Fisheries Oceanography, EarlyView.
ABSTRACT The Northeast Atlantic is one of the most crucial foraging grounds for juvenile loggerhead (Caretta caretta) and leatherback turtles (Dermochelys coriacea), while also serving as an important fishing area for the Andalusia surface longline fishery. The main aim of present study is to assess the sea turtle interaction with the Andalusia pelagic

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
