    Limited Awareness and Financial Intermediationwith S. Auster

    We study the market interaction between financial intermediaries and retail investors, who not only face uncertainty about the performance of the different investments but also have limited awareness of the available investment opportunities. Intermediaries compete for investors via the menu of investment options they offer. We show that when competition is limited, intermediaries restrict their offers to extreme options, e.g. very risky and very safe products. We also consider investor heterogeneity and show that the presence of sophisticated, fully aware investors can impose a negative externality on investors with limited awareness.

    Optimal Taxation in Occupational Choice Models: An Application to the Work Decisions of Coupleswith G. Laroque · IFS Working Paper W17/07

    We study a general model of occupational choice and optimal income taxation where agents have private cost of work that differ across occupations and have both deterministic and random components. We apply our framework to study the work decisions of couples in an extensive set up and give necessary and sufficient conditions under which joint-working households should be subsidized compared to single-worker households.

    Search and Work in Optimal Welfare Programswith O. Setty and G. Violante · NBER Working Paper 18666

    Some existing welfare programs (“work-first”) require participants to work in exchange for benefits. Others (“job search-first”) emphasize private job-search and provide assistance in finding and retaining a durable employment. This paper studies the optimal design of welfare programs when (i) the principal/government is unable to observe the agent’s effort, but can assist the agent’s job search and can mandate the agent to work, and (ii) agents’ skills depreciate during unemployment. In the optimal welfare program, assisted search is implemented between an initial spell of private search (unemployment insurance) and a final spell of pure income support where search effort is not elicited. The threat of mandatory work acts like a punishment that facilitates the provision of search incentives without compromising consumption smoothing too much.
