This paper studies how firms set contributions to employer-provided 401(k)-type pension plans. Using a reform that decreased the subsidy to contributions to capital pension accounts for Danish workers in the top income tax bracket, we provide strong evidence that employers' contributions are based on their employees' savings preferences. We find an immediate decrease in employer contributions to capital accounts, whose magnitude increased in the share of employees directly affected by the reform. This response was large relative to average employee responses within private IRA-type plans and was accompanied by a similar-magnitude shift of employer contributions to annuity accounts.
I IntroductionWith the decline in the prevalence of defined-benefit pension plans, individual savings in defined-contribution accounts are becoming an increasingly important income source for post-retirement consumption. A large and growing portion of savings balances in definedcontribution accounts is within employer-sponsored pension plans, such as 401(k)s. 1 Recent research has underlined the important role that employers' decisions play in determining employees' actual savings within employer-sponsored accounts, since most workers do not actively deviate from the default options which are set by their employer (Madrian and Shea 2001;Choi et al. 2004; Choi, Laibson, and Madrian 2007;Beshears et al. 2009;Gelber Correspondence to: Torben Heien Nielsen, thn@econ.ku.dk. 1 In 2014, 35 percent ($8.3 trillion) of retirement assets in the US were held in defined-benefit plans, while a much larger share of 58 percent ($13.8 trillion) was held in defined-contribution accounts: 30 percent in Individual Retirement Accounts (IRAs) and 28 percent in employer-sponsored plans, mostly 401(k)s (Choi 2015).

The impact of employers' decisions has also been found to translate into large effects on individuals' overall level of savings (Chetty et al. 2014). This research has led policymakers to consider introducing policies that encourage employer contributions to pension accounts in order to increase individuals' retirement savings (Beshears et al. 2010).But how effectively private firms represent their employees' savings interests remains an open question. In theory, both standard models and models of altruistic planners suggest that firms should have incentives to make efficient savings choices on their workers' behalf. For example, standard models of efficient compensation arrangements by competitive firms (as in Rosen 1974), predict that employers will provide benefits when firms can purchase goods or services more cost-effectively than employees, and will provide the optimal package that their workers will value most highly. 2 Similarly, models of purely paternalistic firms that incorporate individual optimization frictions predict that firms will provi...
