Charitable Giving When Altruism and Similarity Are Linked

Harvard Business School professor Julio J. Rotemberg looks at what makes people decide to contribute to a charity. He focuses on two psychological factors: that people feel better about themselves when other people agree with them, and that people tend to be more charitable to other like-minded people.

A Behavioral Model of Demandable Deposits and Its Implications for Financial Regulation

Depositors are overconfident of their chances of recovering demandable deposits in a bank run. In a recent research paper, professor Julio J. Rotemberg reviews various government regulations available to be imposed on financial institutions—minimum capital levels, asset requirements, deposit insurance, and compulsory clawbacks—to understand how much they can help protect investors.

Can a Continuously-Liquidating Tontine (or Mutual Inheritance Fund) Succeed where Immediate Annuities Have Floundered?

The changeover from defined benefit to defined contributions retirement plans in the United States has created a vast group of individuals that faces (or will face) the difficult problem of using a lump sum of assets to provide consumption for a relatively long but uncertain number of years. Up to this point, however, consumers appear not to have embraced annuitization. HBS professor Julio J. Rotemberg suggests an alternative instrument that, like immediate annuities, provides longevity insurance and postpones income until old age. In the proposed Mutual Inheritance Fund (MIF), a pool is formed by having individuals of a particular age buy shares in a mutual fund. The income from the underlying assets in the mutual fund is reinvested in the fund so that the value of the shares in an individual's name (and possibly also the number of these shares) grows over time. The basic idea behind the MIF is that the shares of pool members who die are liquidated, and the proceeds are then distributed in cash to the remaining members in proportion to the number of mutual fund shares that are currently in their name.
