Save More Tomorrow™: Using Behavioral Economics to Increase Employee Saving

Thaler R, Benartzi S

Journal of Political Economy 112(2004): S164-S187.

As firms switch from defined‐benefit plans to defined‐contribution plans, employees bear more responsibility for making decisions about how much to save. The employees who fail to join the plan or who participate at a very low level appear to be saving at less than the predicted life cycle savings rates. Behavioral explanations for this behavior stress bounded rationality and self‐control and suggest that at least some of the low‐saving households are making a mistake and would welcome aid in making decisions about their saving. In this paper, we propose such a prescriptive savings program, called Save More Tomorrow™ (hereafter, the SMarT program). The essence of the program is straightforward: people commit in advance to allocating a portion of their future salary increases toward retirement savings. We report evidence on the first three implementations of the SMarT program. Our key findings, from the first implementation, which has been in place for four annual raises, are as follows: (1) a high proportion (78 percent) of those offered the plan joined, (2) the vast majority of those enrolled in the SMarT plan (80 percent) remained in it through the fourth pay raise, and (3) the average saving rates for SMarT program participants increased from 3.5 percent to 13.6 percent over the course of 40 months. The results suggest that behavioral economics can be used to design effective prescriptive programs for important economic decisions.


Mobile-izing Savings with Automatic Contributions: Experimental Evidence on Dynamic Inconsistency and the Default Effect in Afghanistan

Blumenstock J, Callen M, Ghani T

🔗 Link
Through a field experiment in Afghanistan, we show that default enrollment in payroll deductions increases rates of savings by 40 percentage points, and that this increase is driven by present-biased preferences. Working with Afghanistan’s primary mobile phone operator, we designed and deployed a new mobile phone-based automatic payroll deduction system. Each of 967 employees at the country’s largest firm was randomly assigned a default contribution rate (either 0% or 5%) as well as a matching incentive rate (0%, 25%, or 50%). We find that employees initially assigned a default contribution rate of 5% are 40 percentage points more likely to contribute to the account 6months later than individuals assigned to a default contribution rate of zero; to achieve this effect through financial incentives alone would require a 50% match from the employer. We also find evidence of habit formation: default enrollment increases the likelihood that employees continue to save after the trial ended, and increases employees’ self-reported interest in saving and sense of financial security. To understand why default enrollment increases participation, we conducted several interventions designed to induce employees to make a non-default election, and separately measured employee time preferences. Ruling out several competing explanations, we find evidence that the default effect is driven largely by present-biased preferences that cause the employee to procrastinate in making a non-default election.


The Personal Side of Relationship Banking

This paper documents a widely overlooked dimension of relationship lending: the personal interaction between the borrower and the lender reduces the willingness of the borrower to engage in moral hazard and default on the loan officer. We conduct a randomized experiment with small business borrowers of the largest commercial bank in India to test the impact of three different levels of interactions between the borrower and the bank. Borrowers who are regularly called either by a single assigned relationship manager or by one manager randomly selected from a small team of managers show much better repayment behavior and greater satisfaction with the bank services than borrowers who either receive no follow up or only receive follow up calls from the bank when they are delinquent. The results are economically and statistically significant: borrowers who receive the more intensive treatment see a large reduction in the number of late payment spells and delinquencies.


Member Centered Credit Union Banking: How behavioral insights can help credit unions better serve members


🔗 Link
A loan application should collect necessary information while providing a painless, easy, and engaging experience for members and potential new members. Our recommendations for improving the loan application process were driven by three behavioral principles essential to the design of any human process: (1) reducing perceived hassles and uncer-tainty wherever possible; (2) avoiding jargon; and (3) designing with potential user error in mind. Our recommen-dations for Alliant included a new process timeline to more accurately set applicant expectations and reflected progress through the application; reframing key decision points to ensure users do not accidentally cancel their applications; and revising language that may be unfamiliar to some applicants, such as “collateral,” “debt-to-income,” and “co-borrower.” These principles and recommendations may seem simple, but through our work we have seen how even small changes can have big impacts on client behaviors. Moreover, as service designers, intimately aware of the loan process, it can be difficult for financial experts to design financial products and services that feel intuitive and easy to understand to new users. Alliant has incorporated the majority of our design recommendations into the new loan application process.


Keeping It Simple: Financial Literacy and Rules of Thumb

Micro-entrepreneurs often lack the financial literacy required to make important financial decisions. We conducted a randomized evaluation with a bank in the Dominican Republic to compare the impact of two distinct programs: standard accounting training versus a simplified, rule-of-thumb training that taught basic financial heuristics. The rule-of-thumb training significantly improved firms' financial practices, objective reporting quality, and revenues. For micro-entrepreneurs with lower skills or poor initial financial practices, the impact of the rule-of-thumb training was significantly larger than that of the standard accounting training, suggesting that simplifying training programs might improve their effectiveness for less sophisticated individuals.


Delivering information about retirement saving among Hispanic women: two Facebook experiments

Blanco L, Rodriguez L

🔗 Link
We conducted two Facebook experiments (the first one during July 21–25, 2016, and the second during April 22–25, 2018) to determine what type of message related to injunctive norms is more effective in getting Hispanic women interested in learning about financial planning for retirement. We also explore how social media tools could be used in future interventions to promote retirement saving among Hispanic women. In both experiments, we found that a message centered on peer influence may be more successful than a message centered on familism in getting Hispanic women interested in learning more about financial planning for retirement. When we disaggregate our data by age and state, we find that click-through rates were higher among Hispanic women between 45 and 55 years old, and the largest numbers of impressions were among Hispanic women in California and Texas. When we disaggregate our data by device, we find that most study participants were reached through an Android smartphone.

Underinvestment in a Profitable Technology: The Case of Seasonal Migration in Bangladesh

Bryan GC, Shyamal Mobarak A

🔗 Link
Hunger during pre-harvest lean seasons is widespread in the agrarian areas of Asia and Sub-Saharan Africa. We randomly assign an $8.50 incentive to households in rural Bangladesh to temporarily out-migrate during the lean season. The incentive induces 22% of households to send a seasonal migrant, their consumption at the origin increases significantly, and treated households are 8–10 percentage points more likely to re-migrate 1 and 3 years after the incentive is removed. These facts can be explained qualitatively by a model in which migration is risky, mitigating risk requires individual-specific learning, and some migrants are sufficiently close to subsistence that failed migration is very costly. We document evidence consistent with this model using heterogeneity analysis and additional experimental variation, but calibrations with forward-looking households that can save up to migrate suggest that it is difficult for the model to quantitatively match the data. We conclude with extensions to the model that could provide a better quantitative accounting of the behavior.
