Information about future pensions leads to increased private retirement savings

New SHARE-based study shows that a better understanding of one’s expected pension contributes to financial security in old age

(February 2018) The changing demographics in industrialized countries place an unprecedented strain on social security systems. With the life expectancy in most developed economies increasing, financing retirement becomes a concept calling for a disruptive reconsideration both by political actors and individuals. As public pension funds alone cannot fully guarantee adequate income in older age, private retirement savings are gaining relevance in industrialized countries.

In 2001, the German government took a decisive step towards adapting to the changing demographic and labour environment and introduced funded pensions – a private pension scheme giving employees an incentivized option to save money for retirement and, thus, compensate for the decreasing statutory pensions. The reform, however, considerably increased the complexity of the pension system and, accordingly, the information need of the population. Taking that into account, the German government introduced an information campaign in the form of annually sent letters providing general information about the pension system as well as personalized data on the projected date of retirement and pension payment. Starting 2005, the government began sending out letters to all individuals of age 27 years or more who have paid social contributions for at least five years. Provided that the campaign did not change the amount of projected pensions but was focused on delivering information, German researchers Dolls et al. analysed if and how the letters had an influence on the financial behaviour of individuals.

Measuring pension expectations and information provision effect

Against the backdrop of previous research stating that individuals tend to overestimate the pension payments they are entitled to, Dolls et al. first examine to which extent that corresponds to the German population. In order to do so, the authors used data from the first two waves (2004 and 2006/2007) of the Survey of Health, Ageing and Retirement in Europe (SHARE) and linked it to administrative records from the German Pension Insurance. To further analyse the hypothesized effect of the annual letter campaign, Dolls et al. explore income tax return data from the German Federal Statistics Office.

Personalized information triggers saving and increased labour earnings

The preliminary SHARE-based analysis confirms the outcomes of previous research: individuals tend to overestimate the pension payment they are to expect upon retirement. Dolls et al. further observe that the majority of people miscalculate their projected pension payments both at mandatory and expected retirement age, suggesting that information provision could indeed serve as a trigger to increase savings and labour earnings. In accordance with this hypothesis, participants found the individualized information on their projected pension to be the most valuable part of the letter.

To estimate the actual effect of the information campaign, the authors examine the differences in retirement savings between different age groups. Overall, the observed disparities were very small, the only exception was found between the age groups at the relevant cut-off, those of 26 versus 27 years olds. In this case the differences in retirement savings rapidly increased after the introduction of the letter campaign and remained more than three times as high in later years compared to the largest differences between other groups. Furthermore, analysis showed that the differences between the 26-27 year olds only became larger when the letters were sent out annually – displaying a causal effect of the letter on retirement savings and labour earnings.

In addition to the immediate impact on financial behaviour, the information campaign proved to have long-term effects on the overall amount of savings. In the three years following the initial receipt of the first letter an increase in household savings was observed – from slightly less than 100 EUR in the year of receipt, to an increase of 286 EUR in the second and 350 EUR in the third year. Dolls et al. observe a similar effect also in regard to labour earnings – in the first year after receiving the letter gross income of the household head increased up to 600 EUR for the annual period and continued going up to around 1000 EUR three years later.

Timely transparency can promote effectiveness of social security systems

“Our findings provide guidance how policies could be designed that effectively increase future pension entitlements”, conclude the authors. Indeed, the short- and long-term effects of the information campaign by the German government can be interpreted as a preventive measure against the demographic challenges that industrialized social security systems are facing. Early information provision on the general structure and personal implications of pension payments can help mitigate financial instability in older age and the individual and societal impediments that come with it.
