This study investigates whether the adverse e¤ects of investors’behavioral biases extend beyond the domain of …nancial markets to the broad macro-economy. We focus on the risk sharing (or income smoothing) role of …nancial markets and demonstrate that risk sharing levels are higher in U.S. states in which investors have higher cognitive abilities and exhibit weaker behavioral biases. Further, s...

This essay introduces a new featured section, to be published in Small Axe annually, that explores the critical vocabulary of field Caribbean studies.

In this paper, we develop a new model to describe a dynamic revenue-sharing problem between an online shopping mall and a store in an E-commerce market. We formulate the revenue-sharing problem as a dynamic principal-agent problem, which is then transformed to a risk-sensitive stochastic optimal control problem where the objective of the risk-averse shopping mall is to find a risk-sensitive rev...

Abstract “Queer” is a relatively recent and somewhat controversial term in African studies. Yet it proving to be productive, not only for understanding subjectivities of sexuality gender, but also situating Africa’s position the larger economy knowledge. Otu van Klinken explore productive tensions between “queer” “Africa,” aim read Africa as queer from Africa. Thus, rather than imagining polar ...

We study the market implications of ambiguity in many common models. We show that generic determinacy is a robust feature in many general equilibrium models that allow a distinction between ambiguity and risk. JEL Codes: D0, D5, D8, G1

This paper studies cross-community risk sharing. There is now a large body of theoretical and empirical work on informal insurance, where people mitigate risk by sharing income. A consistent empirical finding is that risk-sharing is not complete within villages, often the observed sets of individuals.2 One reason, researchers suspect, is that risk-sharing does not take place at the village leve...

This paper considers the formation of risk-sharing networks. Following empirical findings, we build a model where pairs form links, but a population cannot coordinate links. As a benchmark, individuals commit to share monetary holdings equally with linked partners. We find efficient networks can (indirectly) connect all individuals and involve full insurance. But equilibrium networks connect fe...
