Can home-owners benefit from stochastic programming models? A study of mortgage choice in Denmark
The Danish mortgage market is large and sophisticated. However, most Danish mortgage banks advise private home-owners based on simple, if sensible, rules of thumb. In recent years a number of papers (from Nielsen and Poulsen in J Econ Dyn Control 28:1267–1289, <CitationRef CitationID="CR8">2004</CitationRef> over Rasmussen and Zenios in J Risk 10:1–18, <CitationRef CitationID="CR11">2007</CitationRef> to Pedersen et al. in Ann Oper Res, <CitationRef CitationID="CR9">2013</CitationRef>) have suggested a model-based, stochastic programming approach to mortgage choice. This paper gives an empirical comparison of performance over the period 2000–2010 of the rules of thumb to the model-based strategies. While the rules of thumb slightly outperform a passive benchmark on average and are less risky than pure adjustable rate loans, we find considerable gains from using the model-based strategies. Using a strategy that minimizes conditional-value-at-risk lowers average effective yearly interest rate over a 10-year horizon by 0.3–0.9 %-points (depending on the borrower’s level of conservatism) compared to the rules of thumb without increasing the risk. The answer to the question in the title is thus affirmative. Copyright Springer-Verlag Berlin Heidelberg 2014
