Migrant visits over time: Ethnographic returning and the technological turn

This paper reflects on four decades of research (via ethnographic returning) to explore the social transformations in travel and communication technologies that have impacted the lived experiences, and consequently the theoretical conceptualization, of migrant visits. A comparison of migration waves between Italy and Australia reveals both continuities in visiting experience as deeply relational practices that facilitate a mutuality of being, but also transformations brought about by the technological turn. Visits take on different meanings depending on individual/ family life stage, generation, and community and national histories. The capacity for both physical and virtual copresence must be understood as coconstitutive, requiring a temporal perspective. The experiences of immobile migrants in residential care suggest that, in the context of rich histories of copresence over time, digital kinning can provide the capacity to share a mutuality of being that safeguards the socio-relational ties of individual and collective identities and belonging that make us human.     

A Dynamic Equilibrium Model of International Portfolio Holdings

This paper develops a continuous‐time equilibrium model of a two‐country exchange economy with heterogeneous agents and nontraded goods. Nontraded goods play the role of state variables that shift the marginal utility of traded goods. This affects prices and generates dynamic hedging demands that explain the well documented home bias puzzle in international equity portfolios. When calibrated to both consumption and production data, the model is able to generate significative home bias in equity portfolios. A new methodology, based on Malliavin calculus, is presented to solve for the portfolio policies along the equilibrium path. This methodology allows one to reduce the determination of equilibrium portfolio holdings to the solution of a linear algebraic system, rather than a partial differential equation.
