Working Papers

Housing, Mortgages, and Self Control (October 2016)    
Revise & Resubmit Review of Financial Studies, CEPR Discussion Paper 11589

Using a quantitative theoretical framework this paper analyzes how problems of self control influence housing and mortgage decisions. The results show that people with stronger problems of self control are less likely to become home owners, even though houses serve as commitment for saving. The paper then investigates the welfare effects of regulating mortgage products if people differ in their degree of self control. Higher down payment requirements and restrictions on prepayment turn out to be beneficial to people with sufficiently strong problems of self control, even though these policies further restrict access to the commitment device.


Overpersistence Bias in Individual Income Expectations and its Aggregate Implications (with Filip Rozsypal, March 2019)
CEPR Discussion Paper 12028

Using micro level data, we document a systematic, income-related component in household income forecast errors. We show that these errors can be formalized by a modest deviation from rational expectations, where agents overestimate the persistence of their income process. We then investigate the implications of these distortions on consumption and savings behavior and find two effects. First, these distortions allow an otherwise fully optimization-based quantitative model to match the joint distribution of liquid assets and income. Second, the bias alters the distribution of marginal propensities to consume which makes government stimulus policies less effective.

Publication

Rules of Thumb in Life-Cycle Saving Decisions (with Joachim Winter and Ralf Rodepeter), Economic Journal, 122, pp.479–501, May 2012 (Matlab code)

We analyse life-cycle saving decisions when households use simple heuristics, or rules of thumb, rather than solve the underlying intertemporal optimisation problem. We simulate life-cycle saving decisions using three simple rules and compute utility losses relative to the solution of the optimisation problem. Our simulations suggest that utility losses induced by following simple decision rules are relatively low. Moreover, the two main saving motives reflected by the canonical life-cycle model – long-run consumption smoothing and short-run insurance against income shocks – can be addressed quite well by saving rules that do not require computationally demanding tasks, such as backwards induction.
