|November 2012||Active vs. Passive Decisions and Crowdout in Retirement Savings Accounts: Evidence from Denmark|
with Raj Chetty, John N. Friedman, Soren Leth-Petersen, Torben Nielsen: w18565
Using 41 million observations on savings for the population of Denmark, we show that the impacts of retirement savings policies on wealth accumulation depend on whether they change savings rates by active or passive choice. Subsidies for retirement accounts, which rely upon individuals to take an action to raise savings, primarily induce individuals to shift assets from taxable accounts to retirement accounts. We estimate that each $1 of government expenditure on subsidies increases total saving by only 1 cent. In contrast, policies that raise retirement contributions if individuals take no action - such as automatic employer contributions to retirement accounts - increase wealth accumulation substantially. We estimate that approximately 15% of individuals are "active savers" who respond t...

|December 2009||Adjustment Costs, Firm Responses, and Micro vs. Macro Labor Supply Elasticities: Evidence from Danish Tax Records|
with Raj Chetty, John N. Friedman, Luigi Pistaferri: w15617
We show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms. We develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs. In this model, micro elasticities are smaller than macro elasticities because they do not account for adjustment costs and firm responses. We present evidence supporting three predictions of the model by analyzing bunching at kinks using the universe of tax records in Denmark. First, larger kinks generate larger taxable income elasticities because they are more likely to overcome search costs. Second, kinks that apply to a larger group of workers generate larger elasticities because they induce changes in hours co...
