Who Uses the Roth 401(k), and How Do They Use It?

by John Beshears, James J. Choi, David Laibson and Brigitte C. Madrian

Abstract

Using administrative data from twelve companies that added a Roth 401(k) option between 2006 and 2010, we describe the characteristics of Roth contributions. Approximately one year after the Roth is introduced, 9% of 401(k) participants have positive Roth balances. Roth participation is more than twice as high among 401(k) participants who were hired after the Roth introduction than among 401(k) participants who were hired before the Roth introduction. In essence, once an employee joins a 401(k) she becomes passive/inattentive, thereby reducing the likelihood of reacting to the introduction of a new Roth option. Conditional on contributing to the Roth, 66% of employee contributions go to the Roth, and half of employees contribute to both the Roth and another 401(k) account, consistent with a tax diversification motive. Roth usage is decreasing in age, less likely among women, and only weakly correlated with salary and tenure once we control for other employee characteristics.

Frustrated by an inability to convince existing venture capital firms to invest in companies led by women, people of color, and LGBT founders, Arlan Hamilton started her own firm, Backstage Capital, in 2015. Hamilton understood the untapped potential of companies run by underrepresented founders, a group historically excluded from venture capital funding, and was eager to demonstrate the significant returns on investment in such companies. This case explores Hamilton’s nontraditional VC background and her mission to fund startups where at least one founder of the company identifies as a woman, person of color, or LGBT. Now, three years after its founding, Hamilton is considering launching both an accelerator and a fund that will invest exclusively in Black women.

Boxed.com (“Boxed”) is an ambitious e-commerce retailer start-up, founded by visionary CEO Chieh Huang in 2013. From starting in Huang’s garage in 2013, to winning Emerging E-Retailer of the Year in 2016, to having 4 operational distribution centers in 2018, Boxed used a variety of strategies in order to gain customers and grow its presence. This case explores the journey that the scrappy, new entrant navigated as it competed against large, goliath players in an already established retail and e-commerce industry.
