Heterogeneity in decentralized asset markets

Julien Hugonnier

We study a canonical model of decentralized exchange for a durable good or asset, where agents are assumed to have time-varying, heterogeneous utility types. Whereas the existing literature has focused on the special case of two types, we allow agents' uti ...

Online appendix to: Debt dynamics with fixed issuance costs

Julien Hugonnier

We investigate equilibrium debt dynamics for a firm that cannot commit to a future debt policy and is subject to a fixed restructuring cost. We formally characterize equilibria when the firm is not required to repurchase outstanding debt prior to issuing a ...

Closing down the shop: Optimal health and wealth dynamics near the end of life

Julien Hugonnier, Pascal St-Amour, Florian Pelgrin

Near the end of life, health declines, mortality risk increases, and curative care is replaced by uninsured long-term care, accelerating the fall in wealth. Whereas standard explanations emphasize inevitable aging processes, we propose a complementary clos ...

Frictional Intermediation in Over-the-Counter Markets

Julien Hugonnier

We extend Duffie et al.'s (2005) search-theoretic model of over-the-counter (OTC) asset markets, allowing for a decentralized inter-dealer market with arbitrary heterogeneity in dealers' valuations (or, equivalently, inventory costs). We develop a solution ...

Credit market frictions and capital structure dynamics

Semyon Malamud, Erwan Morellec, Julien Hugonnier

We study the implications of credit market frictions for the dynamics of corporate capital structure and the risk of default of corporations. To do so, we develop a dynamic capital structure model in which firms face uncertainty regarding their ability to ...

Capital supply uncertainty, cash holdings, and investment

Semyon Malamud, Erwan Morellec, Julien Hugonnier

We develop a dynamic model of investment, financing, and cash management decisions in which investment is lumpy and firms face capital supply uncertainty. We characterize optimal policies explicitly, demonstrate that smooth-pasting conditions may not guara ...

Asset pricing with arbitrage activity

Julien Hugonnier

We study an economy populated by three groups of myopic agents: constrained agents subject to a portfolio constraint that limits their risk taking, unconstrained agents subject to a standard nonnegative wealth constraint, and arbitrageurs with access to a ...

Event risk, contingent claims and the temporal resolution of uncertainty

Pierre Collin Dufresne, Julien Hugonnier

We study the pricing and hedging of contingent claims that are subject to Event Risk which we define as rare and unpredictable events whose occurrence may be correlated to, but cannot be hedged perfectly with standard marketed instruments. The super-replic ...

Health and (Other) Asset Holdings

Julien Hugonnier, Pascal St-Amour, Florian Pelgrin

Despite clear evidence of correlations between financial and medical statuses and decisions, most models treat financial and health-related choices separately. This paper bridges this gap by proposing a tractable dynamic framework for the joint determinati ...
