COVID-19 has taught us that a pandemic can significantly increase biometric risk and at the same time trigger crashes of the stock market. Taking these potential co-movements of financial and non-financial risks into account, we study the portfolio problem of an agent who is aware that a future...

We investigate whether risk-taking for resurrection type of risk preference (non-constant risk aversion) can increase the probability of achieving inflation-indexed pension benefits at retirement, especially when the starting position is underfunded. By maximizing the expected utility of the...

This paper provides a dual formulation of the optimal consumption problem with internal multiplicative habit formation. In this problem, the agent derives utility from the ratio of consumption to the internal habit component. Due to this multiplicative specification of the habit model, the...

his study develops a rational expectations equilibrium model of IPO underpricing within which the distribution of underpricing is explicitly modeled, as opposed to assumed. Contrary to assumptions of prior studies, IPO quality is not inferred from IPO underpricing, is explicitly defined, and is...

We develop a dual-control method for approximating investment strategies in incomplete environments that emerge from the presence of trading constraints. Convex duality enables the approximate technology to generate lower and upper bounds on the optimal value function. The mechanism rests on...

It is no secret that the rational expectations framework has endured what many consider to be a well deserved bashing. From problems, such as, ad hoc specifications of functional forms for utility functions, to adoption of utility functions as units of modeling, to absence of equilibriums that...

I develop a highly tractable dynamic general equilibrium model with collateralized lending and securitization in which asset-backed securities (ABS) function as a mechanism for risk sharing. Entrepreneurs who face aggregate and idiosyncratic investment risks can borrow from a menu of...

We evaluate the asset pricing implications of a class of models in which risk sharing is imperfect because of the limited enforcement of intertemporal contracts. Lustig (2004) has shown that in such a model the asset pricing kernel can be written as a simple function of the aggregate consumption...

We prove that in smooth Markovian continuous-time economies with potentially complete asset markets, Radner equilibria with endogenously complete markets exist.
