Marketing Effects in a Consumer Credit Market in South Africa

The study investigates whether borrowers' choices can be manipulated by frames, cues, and other features that change the presentation of the choice, but not its actual content or inherent value.  IPA partnered with a consumer lender in South Africa to identify which psychological features of a mass-mailing advertising campaign are the most effective. Showing a photo of an attractive woman increased demand for the loan by the same amount as a 25% reduction in the monthly interest rate.

 
Policy Issue: 

Firms in all industries together spend billions of dollars each year advertising consumer products to influence demand, and microfinance institutions are no exception. Economic theories emphasize the informational content of advertising, but advertisers also spend resources trying to persuade consumers with “creative” content and design elements that are not purely informational. Advertising decisions are not inconsequential: decisions about whether to take up loans or savings accounts may be a crucial component of the success of interventions aimed at increasing access to financial services. Although laboratory studies in marketing have shown that “creative” content may affect demand, academic researchers have rarely used field experiments to study advertising content effects. Thus, although attempts to persuade consumers with non-informative advertising are common, little is known about how and how much such advertising influences consumer choice in natural settings like South Africa.   

 
Context of the Evaluation: 

Credit Indemnity, the cooperating consumer lender in this study, has operated for over 20 years as one of the largest, most profitable lenders in South Africa. The lender offers small, high-interest, short-term, uncollateralized credit with fixed monthly repayment schedules to the working poor, who generally lack the credit history or collateral wealth needed to borrow from traditional institutional sources such as commercial banks. The available data suggest that borrowers use their loans for a variety of consumption and investment uses, including food, clothing, transportation, education, housing, and paying off other debt.

 
Details of the Intervention: 

Working closely with a highly profitable consumer lender in South Africa, researchers sought to determine the effects of advertising content, price, and offer deadlines on loan take up. The lender sent direct mail solicitations to 53,194 predominantly urban former clients offering them a new loan at randomly assigned interest rates ranging from 3.25 percent per month to 11.75 percent per month. These mailers varied in a number of ways. First, there were eight variations in advertising content– (1) a person’s photograph on the letter, (2) a suggestion of how to use the loan, (3) a table featuring either a small or large number of example loans, (4) information about interest rate and payments, (5) a comparison to competitors’ rates, (6) mention of a promotional raffle, (7) a reference to the “special” or “low” rate, and (8) a mention of the lender offering services in the local language. Additional randomization included the time before the offer’s deadline, which varied from two to six weeks.

About 8.5 percent of clients who received the mailing applied for a loan, of which approximately 4,000 were approved according to the bank’s established criteria. Because the content of the mailer was recorded in their client profile, researchers could determine what kind of advertising scheme was associated with higher demand for loan products.

 
Results and Policy Lessons: 

Impact of Advertising Content on Demand: All eight advertising randomizations had significant effects on loan take up, but not on loan amount or default rates. Advertising content effects were large relative to price effects. Showing one loan option instead of four increased demand by the same amount as a 25 percent reduction in the monthly interest rate. Showing a female photo or not suggesting a particular use for the loan also had a similar effect.  These results suggest that seemingly non-informative advertising may play a large role in real consumer decisions.

Impact of Advertising Channels: Clients demonstrated the strongest responses to the non-price components of loan offers.  They preferred to be presented with fewer example loans, an attractive photo, and to not be told on what they should consider spending their loan. The success of these features suggests that advertising content is more effective when it aims to trigger an intuitive, or quick, effortless response, rather than a deliberative, or conscious, reasoned response.  

Impact of Deadlines: In contrast with the view that shorter deadlines help overcome limited attention or procrastination, there was little evidence that shorter deadlines increased demand. In fact, demand increased dramatically as deadlines randomly increased from two to six weeks. Even in a competitive market setting with high rates and experienced customers, subtle psychological features appear to be powerful drivers of behavior.

Clean Water in Northern Ghana

This study assesses the willingness of households in Northern Ghana to purchase a ceramic water filter. The Kosim filter is sold by Pure Home Water (PHW), a Ghana-based NGO, and has been demonstrated to be highly effective at improving water quality without needing electricity. We will also measure the health effects of household-level water treatment in areas with high waterborne disease loads.  

Policy Issue: 

Diarrheal diseases, which result poor water quality, are a leading cause of death in the developing world, killing approximately 1.8 million people per year. Achieving the Millennium Development Goals of reducing the proportion of people without sustainable access to safe drinking water is especially difficult for the rural poor. Delivering treated water through pipes has resulted in sustained health gains in developed countries and urban areas in developing countries, but is not considered feasible in rural areas with dispersed populations and weak institutions for maintenance. Community interventions, such as spring improvement or communal wells, have not produced strong results, and policy makers are increasingly interested in household and point of use treatments. However, the effectiveness of such treatments in rural environments, the role of education and marketing to encourage use, and how to expand access with limited resources remain largely unknown.

Context of the Evaluation: 

Diarrheal diseases account for 12% of childhood deaths in Ghana, and are the third largest cause of death for children under the age of 5. These diseases are caused by the ingestion of water contaminated by fecal matter, and 20% of Ghana’s population does not use an improved water source. The sparsely populated northern region of Ghana is one of the least developed parts of the country, and has even less access to clean water than the national statistics would suggest. The majority of its residents make their living in agriculture, living far away from one another. This low population density makes any state- or community-wide water treatment intervention costly and impractical.

Details of the Intervention: 

This study will evaluate the demand, use, and impacts of one household level water treatment technology. The Kosim filter is a ceramic filter marketed and sold by Pure Home Water, a Ghana-based NGO. This simple product has been proven to be highly effective at improving water quality and is appropriate for the region, since it removes particles and pathogens from water without the use of chemicals or electricity which require some form of delivery.

Researchers are measuring the willingness to pay of households for the Kosim filter by offering a random selection of households the opportunity to purchase the filter through door-to-door sales. Households will also be offered a randomized price for the filter, to determine price effects and willingness to pay for preventive health technologies.

Researchers will collect data from 1,500 households on water quality, education, income, consumption, health, diarrhea disease knowledge and water treatment and storage practices to see how these variables affect the willingness to pay for a filter. The randomized offer price provides a means to estimate the filter’s health impact and health spillovers among neighbors, without letting a set price screen out households who have a lower value for clean water. Thus, researchers can evaluate different techniques for creating behavioral change, such as the adoption of new water treatment technologies and storage techniques, and the propensity of individuals to drink treated water and provide treated water to their children.

Text Message Reminders and Incentives to Save in Bolivia

Policy Issue:

Due to the absence of efficient credit and insurance markets, household savings are often a crucial determinant of welfare in developing countries. Without savings, households have few other mechanisms to smooth out unexpected variations in their income, and so shocks, such as health emergencies, can force households into selling assets or taking on debt. Additionally, since savings are one of the few means to accumulate assets in the absence of credit and insurance markets, the capacity to save becomes one of the main vehicles of social mobility and of enhancing future income-earning possibilities. Many people express a desire to save more in the future, but when the time comes, find it difficult to do so. Financial institutions have designed saving products to help clients commit to saving in the future, however the effectiveness of many such products has yet to be evaluated.

Financial institutions have designed saving products to help clients commit to saving in the future, however the effectiveness of many such products has yet to be evaluated.

Context of the Evaluation:

The savings rate in Bolivia is low compared to elsewhere in the South American region. Encouraging savings, however, can be costly and risky. Since microfinance institutions (MFIs) often struggle to control costs and are highly risk averse, many MFIs in Bolivia have preferred to recapitalize their loan portfolio with ‘easy money’ such as donor funds and concessionary loans. However, some MFIs in Bolivia are now beginning to realize that, while savings services seem to be more costly and risky relative to other sources of financing, they may be handicapping themselves by not developing robust deposit taking services and the systems to support them. Clients of the for-profit bank Ecofuturo express a clear desire to save: over 56,000 clients held savings accounts in 2008, a greater number even than the approximately 42,500 active borrowers.[1] One of the savings accounts offered by the bank is a “programmed” savings account, which offers clients a favorable interest rate and free life and accident insurance in exchange for making regular deposits and accepting limits on withdrawals.  In particular, clients must make a deposit each month and can withdraw funds from the savings account only in the month of December.   Yet despite the popularity of the savings accounts, over 40% of savings clients fail to deposit each month as required.

Description of Intervention:

Researchers are working with Ecofuturo to measure the effectiveness of sending text message reminders to clients holding these programmed savings accounts.  The evaluation focuses on a specific programmed savings account called Ecoaguinaldo that is similar to a Christmas Savings Club. The Ecoaguinaldo mimicks the aguinaldo, the year-end bonus many salaried Bolivians receive at the year’s end. The Ecoaguinaldo is used by unsalaried workers and those who want to supplement existing savings accounts, as well as by small business owners who wish to ensure that they have sufficient funds to provide their employees with the expected holiday bonus.  Clients typically open an Ecoaguinaldo account at the beginning of the year and withdraw the savings they have accumulated over the year in December. Receiving a lump sum in December allows clients to meet their end-of-the year financial obligations. The text message reminders provide an opportunity to explore what types of messages are most effective at motivating clients to follow through on their desires to save.

Half of the savings clients with a listed cell phone number were randomly selected to receive a monthly text message reminding them about their Ecoaguinaldo account. There were four distinct messages, which combined a mention of either the savings goal (monthly goal amount in order to receive a year end monetary bonus) or the reward (an active and free life insurance product if all monthly deposits made), and framed the message as either a loss or gain.  The messages to the four treatment groups were:

1.   Goal-Gain: Earn your Aguinaldo! With this month's deposit you will be one step closer to reaching your savings goal.

2.   Goal-Loss: Don't fail to earn you Aguinaldo! If you miss this month's deposit you may not reach your savings goal.

3.   Reward-Gain: Earn your reward! Don't forget you deposit this month. Remember, you will earn a reward of X if you make all of your deposits on time.

4.   Reward-Loss: Don't lose your reward! Don't forget you deposit this month. Remember, you will lose your reward of X if you do not make all of your deposits on time.

Half of the people who received messages in 2008 were in the comparison group the next year, so that the impact of receiving messages one year but not the next could be measured. In the last three months of the project in 2008, the number of treatments was doubled to eight. Each of the four original treatments were split in half, and preceded by the phrase “Ecofuturo supports your decision to save,” to one of the halves. Based upon the 2008 results, in 2009 only messages that focused on the reward were sent.

Results and Policy Lessons:

Overall the reminder message increased savings balances weakly (not statistically significant) and the probability of meeting the savings goal of making one deposit a month by 3%. When results are pooled across similar experiments in Peru and the Philippines, we increase the power of our study, finding the same sized effects statistically significant at the 10% level for savings balances and the 1% level for the proportion of clients meeting their goal.  Messages that mentioned the incentives of maintaining your life insurance policy and receiving reward interest were most effective, increasing savings balances by 10%.  We see no difference between the effectiveness of messages framed with “gain” and “loss language.”  Preliminary results from 2009 suggest that the effectiveness of reminders may decrease over time.  The increase in savings due to the reminders was large enough to make it a profitable venture for the bank. Moving forward, reminders will be a standard component to the bank’s programmed savings accounts.

Text Message Loan Repayment Reminders for Micro-Borrowers in the Philippines

Policy Issue:

The recent and rapid growth of the microfinance industry in the developing world can be attributed, in large part, to the achievement of impressively high loan repayment rates among microborrowers. However, although final default rates are low amongst microfinance borrowers, late repayment is a much larger issue. While microborrowers have surprised skeptics with their ability to repay loans, microfinance institutions (MFIs) and commercial banks lending to the poor still struggle with relatively high transaction costs and low rates of return. All types of MFIs, from strictly for-profit to mission-oriented, would benefit from inexpensive mechanisms for boosting timely repayment rates and lowering administrative costs per borrower. One such solution may be automated loan repayment reminders sent via text (or SMS) on mobile phones. This study tests the effectiveness of one such intervention in improving repayment and reducing default.

Context of the Evaluation:

Known as the text message capital of the world, the Philippines witnesses the transmission of over 1 billion text messages every day and thus offers a prime setting for testing the effectiveness of text message reminders on improving client repayment rates.

IPA, in partnership with Microenterprise Access to Banking (MABS) and two rural banks in the Philippines, designed a study to test the effectiveness of text message reminders as a tool for boosting repayment among micro-borrowers.  Both banks are for-profit institutions that operate individual-liability microfinance lending programs. All new clients at select branches of both banks who had provided cell phone numbers to the bank and who availed of these loans during the study period were automatically enrolled in the study.  MABS, a national initiative established to expand financial services, provides technical assistance and training to local banks.

Description of Intervention:

IPA randomly assigned approximately 1,259 new borrowers who had just received their first loans from their respective banks into a comparison group or one of 12 treatment groups (with various combinations of timing, framing, and personalized messages).  Beyond assessing the overall impact of text reminders, the study was designed to explore the importance of timing, framing and personalization of the text message reminders. Regarding timing, researchers explore whether messages received two days before the due date, one day before the due date, or on the due date itself prove to be the more useful for reminding borrowers to pay. Secondly, the framing, or psychology, of the message sent was varied between emphasizing either the benefit of compliance or the cost of non-compliance to motivate repayment. Finally the importance of personalizing the text message was assessed by comparing messages with the account officer’s name with those containing the client’s name.

Over the course of 16 months between January 2009 and April 2010, cell phone numbers and payment due dates were submitted by the three partner banks on a weekly basis to an automated text message application that sent the assigned text message to borrowers on the appropriate date. All loans required payments on a weekly basis, and the average loan term at the Rural Bank of Mabitac was three months, while the average loan term at Green Bank was six months.

Following the enrollment of clients into the study, IPA analyzed bank data through June 2010 to examine differences in repayment rates, instances of default, and late payments across the 12 treatment groups. IPA also analyzed the cost of the text message system to the banks, taking into account loan officer time, cost of the software development, and administrative costs.

Results and Policy Lessons:

Credit with Health Insurance: Evidence from the Philippines

The addition of health insurance to microcredit products is increasingly popular; but is it sustainable for microfinance institutions? This study complements other IPA research on hospitalization insurance in the Philippines and should provide important policy lessons on providing public services. We partner with Green Bank to evaluate the impact of providing access to the national health insurance program (PhilHealth) among microfinance clients.  Anecdotal evidence from Green Bank field staff suggests that illness among clients and their families is one of the biggest causes of delinquency.  The PhilHealth program offers an opportunity to reduce clients' vulnerability to unexpected health shocks. 

Policy Issue:

Health shocks, such as illness or injury, have the potential to cause significant financial strain for low income households, possibly contributing to late payment or default among microcredit borrowers. Insurance could protect households from health shocks, but is unavailable to many in developing countries. High transaction costs and information problems complicate efforts to offer health insurance in a cost-effective way. There is also potential for moral hazard: once clients become insured, they may be less inclined to care for their health. Adverse selection may also occur, as clients predisposed to sickness may be those most willing to purchase insurance, dampening the profitability of insurers. But research has failed to produce a consensus on the impact of adverse selection and moral hazard for insurers in the developing world. How will these impact the market for health insurance? And how will health insurance impact the lives of microcredit clients?

Context of the Evaluation: 

The majority of residents in the Visayas and Northern Mindanao regions of the Philippines live in small towns and rural villages. A large for-profit bank, The Green Bank of Caraga, has been a strong presence in these regions for the past decade. The majority of microfinance clients they service engage in small-scale sales or work as tailors, drivers of local transport, and operators of bakeshops and roadside eateries. Anecdotal information suggests that health shocks are a leading cause of default and drop-out among their clients. Most of the respondents in this study reported that their ability work or do related productive activities was restricted at least some of the time.

Details of the Intervention: 

Researchers worked with the health insurer Philippine Health Insurance Corporation (PhilHealth), which offers the KaSAPI program to help organizations such as microfinance institutions provide affordable health insurance to their members. KaSAPI provided information about the availability and benefits of the insurance to microfinance clients through a marketing campaign. Bank clients were able to use existing savings or loan proceeds to pay for the insurance premium of 300 Philippine Pesos (approximately US$6) per quarter.

Clients were randomly assigned to compulsory insurance, voluntary insurance, or no insurance to serve as a comparison. For clients in the voluntary treatment group, loan officers presented the schedule of PhilHealth benefits and explained that the bank was offering KaSAPI as an optional service for its clients. Premiums were deducted from the loan proceeds. For clients in the compulsory treatment group, loan officers presented PhilHealth materials but also explained that PhilHealth was now a requirement to continue participating in the lending program. Clients’ loans in compulsory PhilHealth treatment group were not released unless they agreed to the premium deduction from their loan proceeds.

End line surveys will establish whether access to health insurance increased risk-taking behavior, if it improved the health status of beneficiaries and if formal insurance crowded out informal insurance arrangements. Evidence will also reveal how health insurance affected institutional outcomes such as profit, client retention, and default.

Market Structuring of Sludge Management for the Benefit of Vulnerable Households in Dakar

Poor sanitation in the developing world leads to childhood diarrhea, a leading cause of mortality in children under five.1 This project seeks to identify ways to increase demand and reduce prices for an improved sanitation technology, mechanical desludging. Researchers are measuring the effects of social and behavioral factors (social pressure, learning, and payment formats) on household demand, and the effect of different auction mechanisms on collusion and prices paid by consumers.

Policy Issue:
In urban areas of developing countries where houses are not connected to publicly-provided sewer systems, a household’s waste goes into its own septic tank or unimproved pit, which then has to be emptied, or “desludged.” A household can either pay to have the pits shoveled out manually, which often means dumping it near adjacent homes, posing health hazards to both workers and residents, or hire a mechanized desludger which pumps the sludge into a truck that then delivers the sludge to a treatment plant. Mechanized desludgers are more expensive, but also more sanitary. Because they are often underutilized, research is needed to better understand how to increase demand and decrease prices for these services.
 
Context of the Intervention:
In Dakar, Senegal, waste pits fill on average every six months, but only an estimated 30 percent of households use mechanized desludging because of the expense. Estimates suggest that a mechanized desludging costs approximately five days’ wages while a “baay pelle” (a worker who shovels the pit manually) costs approximately two days’ wages. The Office National de l’Assainissement du Senegal (ONAS), part of the Senegalese Ministry of Sanitation, is seeking to identify ways to boost usage of the more expensive, but more sanitary, mechanized desludging.
 
Details of the Intervention:
This project seeks to understand how to increase use of mechanized desludging, from both the demand (customer) side and supply (provider) side. 
 
Demand Side Interventions:
Four thousand households will be randomly assigned to receive a discount of either 10 or 50 percent on mechanized desludging services. To understand the extent to which social pressure influences use of mechanized desludging, this discount will be made by public lottery for half of the households, and for the other half it will be offered privately. A further 800 households will be surveyed to evaluate the effects on those nearby who were not offered subsidized mechanized desludgings.
 
The impacts of learning from others and coordination will be measured when 100 randomly chosen households are told either how many or specifically which of their neighbors have signed up, and are then given the opportunity to sign up. To measure learning from doing, researchers will see whether those who received subsidized services continue after the discount ends. 
 
A number of payment structures will also be tested. Eighty percent of households will be asked to leave a deposit at the time of the survey if they would like to sign up for the subsidized mechanized desludging. One third of households will be asked to pay the remainder at the time of service, one third will be given a savings account earmarked for desludging and billed monthly, and one third will be given the same earmarked savings account, but allowed to contribute whenever they wish. Half of households will also be offered a general, non-earmarked savings account. Varying the frequency of payments and savings options will test the relative importance of commitments and mental accounting to encourage payment and usage.
 
Supply Side Interventions:
Anecdotal evidence suggests that desludging firms discuss prices among themselves and coordinate pricing for the different neighborhoods of the region. A new call center, developed by the researchers together with ONAS and the NGO Water and Sanitation for Africa (WSA), will handle contracting of desludging jobs for households in the study. When households are ready for desludging, they can call the center and desludging truckers will bid on their job using text messages. The new call center will allow researchers to test whether changing the auction mechanism can lower pricing for customers. Jobs will be assigned randomly to either an open auction, with the current lowest bid and firm name sent out by text message every 15 minutes, or a sealed bid format, where bidders compete anonymously. This randomization will test if either bidding strategy leads to lower prices than the current system, which involves customers negotiating individually with truckers.
 
This call-in center will not only be available to those households participating in the demand-side interventions; it will also be available to households across Dakar, with a geographic roll-out over time. Together with WSA, researchers are surveying an additional 4,000 households in baseline, midline, and endline surveys to estimate the impact of the roll out of the call-in center on the general unsubsidized population. These households will be far enough away from the demand-side households that they should not be affected by the subsidies offered to those households. Researchers are also surveying all 150 sanitation truckers in the Dakar area.
 
Results and Policy Lessons:

Finding Missing Markets: An Agricultural Brokerage Intervention in Kenya

Policy Issue: 

In much of the developing world, farmers grow crops only for local or personal consumption, despite export options which are thought to be much more profitable. There are several plausible reasons why farmers might choose to grow crops for local markets, forgoing the opportunity to make more money through export crops. There may be information gaps about profitability of export crops, lack of access to the capital needed to make the switch to export crops, inadequate infrastructure to bring crops to urban centers, concern over risky export markets, or misinterpretation by researchers as to the true profit opportunities. 

Context of the Evaluation: 

Kenya’s horticultural sector, which includes fruit and vegetable production, has received a great deal of attention over the past decade due to the rapid and sustained growth of its exports to Europe. Although Europe’s appetite for Kenyan agriculture exports has been great, small farmers have largely failed to cash in on this opportunity. Many farmers instead receive below-market prices for their crops by selling them at the local market or to intermediaries, who then resell the produce at regional market centers or to export firms. In the study sample, about half of the household income came from agriculture, and most owned the land they cultivated, which was usually about one acre. Farmers grew subsistence crops (beans, maize, potatoes, and kale) 50 percent of the time and cash crops (coffee, bananas, and tomatoes) 34 percent of the time. Only 12 percent of farmers grew any export crops.  

 
Details of the Intervention: 

In collaboration with DrumNet, a Kenyan NGO, researchers evaluated whether a package of services could help small farmers adopt, finance, and market export crops, and thus make more income. DrumNet tried to link smallholder farmers to commercial banks, retail farm suppliers, transportation services, and exporters. To be a member of DrumNet, a farmer had to be a member of a registered self-help group (SHG), express interest in growing export crops marketed by DrumNet (i.e. French beans, baby corn, or passion fruit), and have irrigated land. 

In 2003, researchers randomly divided the 36 active self-help groups (SHGs) in the Gichugu area into three equal groups: the first treatment group received all DrumNet services; the second treatment group received all DrumNet services except for credit; and the third served as the comparison.

All individuals in the two treatment groups received a four-week orientation course, which explained the financing and selling process, and good agricultural practices. In additional, all treatment individuals opened a personal savings account with a local commercial bank to accommodate possible future business transactions. Individuals in the credit treatment group also contributed the equivalent of a week’s labor wages to an insurance fund, which would serve as partial collateral for a line of credit. After being organized into groups of five, which were jointly liable for individual loans taken out, individuals in the credit treatment group received an in-kind loan from a local agriculture supply store.

At harvest time, for individuals in both treatment groups, DrumNet negotiated prices with an exporter and arranged a produce pickup. Once the produce was delivered to the exporter, the exporter payed DrumNet who, after deducting any loan repayments, credited the remainder to the individual savings accounts that each farmer opened when they registered. 

 
Results and Policy Lessons: 

Impact of the DrumNet Program: One year after the program began, treatment individuals were 19.2 percentage points more likely to be growing an export crop, but there were no significant gains in income for the full sample. However, among first-time growers of export-oriented crops, program participation led to a 31.9 percent increase in income.

Out of the twelve SHGs in each treatment group, ten decided to take advantage of DrumNet services when credit was offered, compared to only five of twelve when it was not, implying that farmers perceived credit as an important factor for cultivating export crops. However, access to credit had no effect on income gains compared to no-credit SHG groups. 

Long-term Consequences: Unfortunately, one year after the evaluation ended, the exporter refused to continue buying from the DrumNet farmers since none of the SHGs had obtained EU export certifications. This led to DrumNet’s collapse as farmers’ export crops were left to rot and loans went into default. Farmers returned to growing for local markets, underscoring the original concerns over export market risk. 

 

Demand for Rainwater Harvesting Devices in Uganda

Poor access to safe drinking is an acute problem in many developing countries which has both health and social repercussions. In order to improve access to safe drinking water, Relief International (RI) has developed a rainwater storage device (RSD), which consists of a rubber bag approximately 1.5m across and 1.5m tall when full. Researchers are evaluating this new technology in Kamwenge district in Uganda. 

Policy Issue: 

Poor access to safe drinking is an acute problem in many developing countries which has both health and social repercussions. Lack of safe water for drinking, bathing, and other household tasks is the primary cause of diarrheal diseases, which account for 15 percent of deaths among children under five years of age.[1] Poor access to water also entails large time costs associated with gathering water. In some parts of Africa, women spend up to eight hours per day collecting water. New technologies, such as rainwater storage devices, could improve access to safe drinking water and decrease the time needed for water collection. However, such new technologies are only useful to the extent that they are affordable and acceptable to the intended beneficiaries. Before any large investments are made in the development and distribution of a technology, it is necessary to determine the potential size of the market, the most effective marketing strategies to promote adoption, and the potential impacts it could have on the lives of the poor.

Context of the Evaluation: 

In order to improve access to safe drinking water, Relief International (RI) has developed a rainwater storage device (RSD), which consists of a rubber bag approximately 1.5m across and 1.5m tall when full. The bag is held up by a simple earthen foundation and is fed by a series of gutters. It can hold up to 1000 liters of water, which is estimated to meet the basic needs of a family of five for ten days. 

Researchers are evaluating this new technology in Kamwenge district in Uganda. Residents of Kamwenge are particularly likely to benefit from a rainwater storage device, as the district receives substantial rainfall during the two rainy seasons – the first and smaller of the two lasts from the end of February to the end of April, while the second and longer season lasts from mid-September to the beginning of December. 

Details of the Intervention: 

This study will assess the demand for rainwater storage devices and determine potential marketing strategies. Specifically, researchers will randomly vary the incentives and marketing conditions associated with the sale of rainwater storage devices to different households. Researchers will experimentally vary the price for the device by offering discount vouchers to random subsets of households.

Researchers will also randomly apply two different marketing schemes across villages. In the first scheme, a product ambassador will be chosen from each village and given training and materials to promote the device within the village. In the second marketing scheme, the first household within each village that purchases the device at full price will receive free installation. Both marketing schemes are intended to increase locally available information about the device and promote take-up by others in the village. 

The intervention will be implemented in two distinct waves spread 6 months apart, in order to study the importance of information transmission in generating demand for the new technology. For instance, it may be the case that second-wave households would have had some indirect experience with the new technology through their friends who adopted in the first wave, affecting their likelihood of adoption. The two-wave strategy also creates the opportunity to examine whether the overall level of demand changes once society becomes more familiar with the product and its price is anchored. 

A follow-up survey will measure women’s participation in the workforce, child school attendance, and changes in household economic activity among adopters and non-adopters.

Information Campaign to Reduce Plastic Bag Consumption in Supermarkets in Mexico

 

Between 500 billion and a trillion plastic bags are consumed worldwide each year. The negative environmental consequences of plastic bags are well documented. Understanding consumers’ behavioral responses to campaigns, nudges and regulations is a key policy question in this field.

 

Between 500 billion and a trillion plastic bags are consumed worldwide each year. The negative environmental consequences of plastic bags are well documented. Understanding consumers’ behavioral responses to campaigns, nudges and regulations is a key policy question in this field.

During July, August, and September of 2010, researchers partnered with the Mexican supermarket company, Comercial Mexicana, to study the impacts of different in-store communication strategies. A total of 199 supermarkets participated in the study. Two different kinds of messages were tested: one stressed the environmental impact of plastic bag consumption, while the other stressed the importance of caring for future generations. These messages were randomly delivered using two different media: graphic banners and posters in key locations in the store, or through the in-store digital audio system of the stores at 15 minute intervals.

Researchers measured the effects of these campaigns on 1) consumption of plastic shopping bags dispensed at the cashier, and 2) sales of reusable bags.

Results are forthcoming.
