The so-called "retirement saving puzzle" is the phenomenon that many households in the U.S. have significant wealth late in life, contrary to the predictions of a deterministic life-cycle model. In this project, we collect facts on crosscountry differences in saving behavior of retirees, in order to weigh in on the discussion of the puzzle. First, we find that countries in our sample vary noticeably in the extent of the puzzle: one group of countires, in South and Central Europe, look like the U.S., while in another group, in Northern Europe, retirees spend down their wealth much more rapidly. Second, we show that in order to understand the rates of dissaving across countries, one needs to understand differences in housing assets, as housing constitutes the majority of wealth for a median retiree in many countries, and dissaving in housing is highly correlated with overall dissaving. Finally, we examine institutional differences and differences in risks between countries, based on the literature as well as measurement from our data, where possible. These provide a number of promising explanations that should be examined in future research.
