230:, Challe and Ragot (2010) showed that shocks to labor productivity affect firms' incentives to create jobs and hence the expected duration of unemployment spells. When employed workers are imperfectly insured against the occurrence of such spells, they hoard assets for self-insurance purposes. Moreover, during times of recession the precautionary motive for holding wealth is strengthened, causing aggregate saving to rise and aggregate consumption to fall, which in turn affects the propagation of shocks in the economy.
202:
on the empirical literature that while the precautionary motive is important for some people at some times, it is unlikely to be so for most people. In other words, the heterogeneity of consumption/saving behavior of individuals in the economy makes it difficult to precisely quantify the precautionary motive for saving.

precautionary motive for saving and hence holds down consumption spending (cetrus paribus). This in turn justifies the notion that precautionary saving may be part of the explanation of why large consumption falls anticipate large increases in unemployment in response to exogenous shocks to the economy.

The analysis also accounted for the case where market interest rate was higher than the subjective rate of time preference, and provided evidence that individuals will postpone consumption and save by accumulating large stocks of assets. When both rates were equal, given an anticipated shock to the

Dardanoni (1991) proposed that high rates of precautionary saving would simply be implausible, as most saving should come from the top percentiles of the income distribution—i.e., individuals who are not very likely to engage in precautionary saving. Browning and
Lusardi (1996) concluded based

The empirical literature shows mixed evidence on the significance of the precautionary motive for saving. Numerical simulations suggested the possibility precautionary saving, ranging from 20 to 60 percent of all saving. A significant empirical contribution by

Weil (1993) proposed a simple multi-period model to analyze the determinants of precautionary saving. Analytical findings confirmed the presence of a precautionary saving motive, with precautionary saving positively correlated with income risk. More extensive research has confirmed the presence of a

Moreover, insuring industrial workers’ future incomes against workplace accident was used to test the effect of insurance on precautionary savings. This was conducted for 7000 households who did not or could not obtain complete insurance coverage against workplace accident risk, covering 1917-1919.

Subsequent analysis from
Kazarosian (1997), using data from the National Longitudinal Survey, has shown that a doubling of uncertainty increases the ratio of wealth to permanent income by 29%. In addition, surveys have shown that most Americans desire precautionary savings at 8% of total net worth

A step forward was led by
Kimball (1990) who defined the characteristic of "prudence". The measure of absolute prudence was defined as q =-U'"/U", and the index of relative prudence as p=-wU"'/U" (i.e. U is a utility function). The prudence index measures the intensity of the precautionary motive

Not only do individuals accumulate reserves for precautionary purposes, but also sovereigns follow the same behavior. Saving rates of fast-growing emerging economies have been rising over time, leading to surprising “upstream” flows of capital from developing to rich countries. Carroll and Jeanne

Defining this concept, individuals save out of their current income to smooth the expected consumption stream over time. The impact of the precautionary saving is realized through its impact on current consumption, as individuals defer their current consumption to be able to maintain the utility

Because of higher quality data on hours worked, a new literature considered precautionary labor supply, a part of precautionary savings. The findings support modest precautionary saving, which is particularly relevant for self-employed. If the self-employed faced the same wage risk as the civil

Empirical work has mostly focused on the representative individual’s determinants of precautionary saving. More recent work focused on the importance of the time dimension. Under this notion, uncertainty about households' anticipated future income, due to expected unemployment, strengthens the

It was only recently that economists confirmed the early findings of Leland. Lusardi (1998) confirmed that intuitions derived from economic models without a precautionary motive could be seriously misleading, even with small uncertainty.

the current period were seen statistically significant to bridge the gap between current income and the highest previously earned income. Hence, saving was considered a significant hedge against the income fluctuations.

Some examples of events that create the need for precautionary saving include health risk, business risk, unavoidable expenditures, and risk of labor income change, saving for retirement and a child's education.
194:. Findings of the model showed that lower variability of earnings led to a lower saving rate. Also, the saving rate became higher by a range of 7% to 14% as variability of earnings increased.

Leland (1968) introduced a simple analytical framework that builds on the prudence individuals towards risk. This is a concept that economists define as decreasing absolute risk aversion

Economists have realized significance of precautionary saving long ago. Historically, the precautionary motive for saving has been recognized by economists since before the time of

Industrial workers at the time significantly reduced their saving and insurance consumption by approximately 25 percent when their expected post accident benefits increased.
