The U.S. has long incentivized retirement saving in 401(k) and similar retirement accounts by permitting workers to defer taxes on contributions, levying them instead when retirees withdraw funds in retirement. This paper develops a dynamic life-cycle model to show how and whether...

This research project evaluates the extent of heterogeneity in time discounting among elderly Americans, as well as its role in explaining older peoples' key behaviors. We first show how older Americans evaluate simple (hypothetical) intertemporal choices in which payments now are compared with...

The 1965 Immigration and Nationality Act had a profound impact on the demographic and skill composition of immigrants arriving in the U.S. A large literature has investigated the relative earnings of immigrants and natives, but much less is known about relative wealth accumulation and the...

This study analyzes the role of individual's and spouse's survival expectations and knowledge about Social Security rules on the expected Social Security claiming age, taking into account the various incentives single and married individuals face. There is substantial heterogeneity in the level...

Most workers in defined contribution retirement plans are inattentive portfolio managers: only a few engage in any trading at all, and only a tiny minority trades actively. Using a rich new dataset on 1.2 million workers in over 1,500 plans, we find that most 401(k) plan participants are...

The direct financial impact of the financial crisis has been to deal a heavy blow to investment-based pensions; many workers lost a substantial portion of their retirement saving. The financial sector implosion in turn produced an economic crisis for the rest of the economy via high unemployment...

This paper derives optimal life cycle portfolio asset allocations as well as annuity purchases trajectories for a consumer who can select her hours of work and also her retirement age. Using a realistically-calibrated model with stochastic mortality and uncertain labor income, we extend the...

Though millions of US workers have 401(k) plans, few studies evaluate participant investment performance. Using data on over 1,000 401(k) plans and their participants, we identify key portfolio investment inefficiencies and attribute them to offered investment menus versus individual portfolio...

Retirees must draw down their accumulated assets in an orderly fashion so as not to exhaust their funds too soon. We derive the optimal retirement portfolio from a menu that includes payout annuities as well as an investment allocation and a withdrawal strategy, assuming risk aversion,...

We derive the optimal portfolio choice over the life-cycle for households facing labor income, capital market, and mortality risk. In addition to stocks and bonds, households also have access to incomplete annuity markets offering a hedge against mortality risk. We show that a considerable...
