An individual’s decision to consume less and save more reveals information about his or her expectations about future events as well as heterogeneous preferences. Savings may increase, for example, if a household plans high expenditures in the future (house building, education of children) or wants to hedge against negative shocks (illness, unemployment of the breadwinner). We expect a reduction in savings activity when a saver is confronted with new reasons for fearing financial losses in approaching economic or political crises (inflation, bankruptcy, war, or expropriation by an authoritarian regime). It is also possible that the introduction of new or additional transfer payments (pensions, unemployment benefits) crowds out private savings. We will study on which information savers built their optimistic or pessimistic expectations. Do the rely on information provided by the media or do the react to direct economic signals such as changes in the real interest rate? Based on the seminal work of Malmendier and Nagel we assume that a saver’s personal experience has an import impact on his or her individual expectations and savings decisions. People who experienced high inflation in their past, for example, might have higher inflation expectations than people who only know price stability. Our period of observation from 1871 to 1970 comprise many major shocks that might have influenced the savings behaviour of people who personally experienced them. We observe two World Wars and a number of large and widespread economic crises that severely harmed German savers. Just think about the “Gründerkrise” in the 1870s, the hyperinflation in 1923, the currency reform of 1948, the Great Depression, and other smaller crises such as the stock market crash in 1907. Studying savings behaviour based on individual saving books, household books, diaries and other available archival material over this long time span, therefore gives us ideal conditions to study how personal experience have shaped individual savings decisions.

一个人少消费多储蓄的决定揭示了他或她对未来事件的期望以及异质性偏好的信息。例如，如果一个家庭计划未来的高额支出（房屋建设、儿童教育）或希望对冲负面冲击（疾病、养家糊口的人失业），储蓄可能会增加。我们预计，当储蓄者面临新的理由，担心经济或政治危机（通货膨胀、破产、战争或专制政权的征用）即将到来时，储蓄活动会减少。引入新的或额外的转移支付（养老金、失业救济金）也有可能挤出私人储蓄。我们将研究哪些信息保存者建立了乐观或悲观的预期。他们是依赖媒体提供的信息，还是对实际利率变化等直接经济信号做出反应？基于马尔门迪尔和内格尔的开创性工作，我们假设储蓄者的个人经历对他或她的个人期望和储蓄决策有重要影响。例如，过去经历过高通胀的人可能比只知道价格稳定的人有更高的通胀预期。我们从1871年到1970年的观察期间包含了许多重大冲击，这些冲击可能影响了亲身经历过这些冲击的人的储蓄行为。我们目睹了两次世界大战和一系列严重损害德国储户利益的大规模、广泛的经济危机。想想19世纪70年代的“大萧条”，1923年的恶性通货膨胀，1948年的货币改革，大萧条，以及其他较小的危机，如1907年的股市崩盘。因此，在这么长一段时间里，基于个人储蓄书籍、家庭书籍、日记和其他可用的档案材料来研究储蓄行为，为我们研究个人经历如何影响个人储蓄决策提供了理想的条件。
