This paper proposes a formal model of migration in which workers are heterogeneous and markets are stochastically correlated. We derive and characterize the optimal migration pattern. It is shown to depend on differences in expected earnings, costs of migration, income risks, and more...

In this paper, I study the existence and uniqueness of recursive equilibria in economies with aggregate and idiosyncratic risk. Rather than relying on compactness to establish existence, I exploit the monotonicity property of the equilibrium model and rely on arguments from convex analysis. This...

In the aftermath of the financial crisis of 2008, there is increased concern about the potentially catastrophic pension default risk, which results in significant decreases in pension benefits. In order to address the challenge of annuity income uncertainty, I propose a dynamic annuitization...

We develop a retirement model with long-run income risk in which the wealth threshold for retirement is shown to be a function of the extent of the long-run income risk. By devising a new numerical algorithm, we solve the two-dimensional retirement problem. The two-dimensional retirement...

In this paper, we develop a new dynamic programming approach for solving an optimal retirement model in a two-dimensional incomplete market, which is induced by forced unemployment risk and borrowing constraints. We show that the two dimensions jointly affect an individual's optimal consumption,...

We introduce the new class of Performance measures Adjusted for the Risk Situation (PARS), which incorporate individual risk characteristics in the financial performance measure. The (risk) situation of an individual or company is represented by all of its future cash flows including (financial)...

This paper studies how the interaction between two types of uncertainty due to ignorance affects strategic consumption-portfolio rules, precautionary savings, and welfare in general equilibrium. We incorporate these two types of uncertainties into a recursive utility version of a canonical...

We explore how members of a collective pension scheme can share inflation risks in the absence of suitable financial market instruments. Using intergenerational risk sharing arrangements, risks can be allocated better across the various participants of a collective pension scheme than would be...

We develop an analytically tractable model of optimal financing policies for a risk averse decision maker who is exposed to climate risk causing a significant disruption to capital stock accumulation. We quantitatively identify certain thresholds of cash-capital ratio explicitly characterizing...
