This paper characterizes the transition dynamics of a continuous-time neoclassical production economy with capital accumulation in which households face idiosyncratic income risk and cannot commit to repay their debt. Therefore, even though a full set of contingent claims that pay out...

Almost 50 million Americans are burdened by the need to repay almost $2 trillion in student loan debt, while at the same time having to save for retirement. This article analyzes the potential impact of the 2022 SECURE 2.0 Act reform which permits employers to match contributions for student...

A rent guarantee insurance (RGI) policy makes a limited number of rent payments to the landlord on behalf of an insured tenant unable to pay rent due to a negative income or health expenditure shock. We introduce RGI in a rich quantitative equilibrium model of housing insecurity and show it...

This paper evaluates a new variant of the popular target date funds used in employer-based retirement savings plans. We call this new variant a "target retirement plan." Instead of increasing the allocation to bond funds as retirement approaches, a target retirement fund gradually purchases...

This paper investigates retirees' optimal purchases of fixed and variable longevity income annuities using their defined contribution (DC) plan assets and given their expected Social Security benefits. As an alternative, we also evaluate using plan assets to boost Social Security benefits...

Some US defined contribution plans offer retirees access to an annuity or lifetime income stream as payout options from their 401(k) accounts. Nevertheless, for behavioral reasons, some retirees may hesitate to elect lifetime income streams as a drawdown vehicle. To counter this, plan sponsors...

This paper defines risk-on risk-off (RORO), an elusive terminology in pervasive use, as the variation in global investor risk aversion. Our high-frequency RORO index captures time-varying investor risk appetite across multiple dimensions: advanced economy credit risk, equity market volatility,...

Over the last two decades, the unprecedented increase in non-bank financial intermediation, particularly open-end mutual funds and ETFs, accounts for nearly half of the external financing flows to emerging markets exceeding cross-border lending by global banks. Evidence suggests that investment...

We study sources and implications of undiversified portfolios in a production-based asset pricing model with financial frictions. Households take concentrated positions in a single firm exposed to idiosyncratic shocks because managerial effort requires equity stakes, and because investors gain...

We study optimal policy when heterogeneous markups reflect compensation for uninsurable persistent idiosyncratic risk. The optimal labor tax keep rate equals (1) the aggregate markup times (2) workers' consumption share divided by their Pareto weight. Markups correctly capture the private cost...
