        <p>This paper focuses on how small business owners' local financial practices in underrepresented communities can support economic independence, growth, and resilience for these businesses and, at the same time, for the community to which they belong. We propose here a model based on microbanking, that is, the transformation of small business owners into managers of very small banks which provide microcredit to their communities. The idea is based on findings and learnings from a past project with Brazil's largest micro-credit institution. Our proposal looks, in particular, into how AI technology can ethically mine the knowledge some people in those communities (e.g., small shop owners) have about the financial life and status of other members and leverage it to enable micro-loans to the whole community, supporting at the same time the small-business owners on credit and cash flow provisions.</p>

      <title>Introduction</title>
      <p>
        During a project done by the IBM Research Brazil
laboratory in 2015 with the largest micro-credit provider in Brazil,
we observed that small business owners (SBOs) of poor
communities often allowed some members of their
community to pay later for goods and services, a practice known
locally as “fiado” (e.g., a kind of store credit; “put on my
tab”)
        <xref ref-type="bibr" rid="ref1 ref2 ref3">(Candello et al. 2018, 2016; Bianchi et al. 2017)</xref>
        .
      </p>
      <p>By doing so, they were the de facto local micro-loan
providers, and at the same time, they generated more
revenue for their own business. However, as the SBOs had
cashflow problems, their capacity to exercise credit providers’
role was limited. Moreover, since both the SBOs and their
clients were often part of the informal economy and often
had issues with their credit scores, their access to traditional
credit lines from banks was virtually nonexistent.</p>
      <p>“Fiado”, is, in fact, a common practice of many
communities, especially ones where racial and ethnic constraints the
ability of their members to get access even to simple forms
of credit provision such as credit cards. A common
impediment for getting credit cards and similar financial
instruments is a lack of or bad credit history. Financial institutions
are often at loss to provide credit to people without those
instruments, which often do not exist in informal economies.

ICnrteealltiigveenCcoem(mwownws.Laiacaein.osergA).ttAriblultrioignh4ts.0rIensteerrvneadtio.nal (CC BY 4.0).</p>
      <p>However, in our study we observed that, in deciding who
should get “fiado” or not, the SBOs displayed a remarkable
level of knowledge of the financial situation and ability to
repay of their community members. What if, with the help
of AI technology, that knowledge could be mined and
formalized in some form, allowing banks and other financial
institutions to provide loans to people marginalized from
traditional credit systems using the SBOs knowledge?</p>
      <p>To materialize that particular scenario, we envisioned an
electronic ledger for the SBOs, modified to include the
“fiado” transactions, which could become a platform for
providing credit to customers and, at the same time, solve some
of the cash-flow problems of the SBOs (borrowing from
delayed income). In many ways anticipating the “sharing
economy”, we proposed the transformation of the SBOs into
micro-bankers, bringing credit to highly under-served
communities and to themselves.</p>
      <p>
        Unfortunately, both the technological limitations of the
SBOs and the novelty of sharing mechanisms prevented that
idea to be tested at that time. Fast-forwarding 5 years,
providing credit to people with limited or problematic credit
historical data is still a practical challenge, in particular for
poor and minority communities. In such a way, similar
cashflow difficulties for SBOs in such underrepresented
communities are still common and recently much aggravated by
the COVID pandemic and associated recession
        <xref ref-type="bibr" rid="ref5">(Dua et al.
2020)</xref>
        . However, advances in AI technology, Internet access,
and electronic payment have progressed to a point where
many of the project’s original technical challenges no longer
stand out. Also, sharing and gig economy platforms are now
mainstream and part of the daily life of most people,
including ones from those poor and minority communities.

      <title>The Time for Microbanking</title>
      <p>We see this moment of difficulties and need for advancement
of discriminated communities and groups as an opportunity
to explore some of the ideas from the initial project and
revisit them in the current temporal context and low-income
communities in different parts of the globe. We are
exploring the current financial context of credit access of SBOs and
their clients in two geographical contexts (US and Brazil)
and we envision proposing solutions based or adapted from
the previous ideas to such contexts. We aim to develop
technologies and tools that would enable testing the proposed
solutions in the context of the studied communities. If
successful, the solution could be scaled up with the support of
partner banks.</p>
      <p>
        To do so, we are addressing this issue by combining the
inherent community-based and community-oriented nature
of SBs and an emerging discovery-driven approach to
enable minority-owned SBs to better manage their financial
situations at the community scale. By discovery-driven
approach, we mean creating mechanisms whereby SBOs could
explore various financial and decision scenarios testing
hypotheses via what-if scenarios. We postulate that these
scenarios would be drawn from behavioral-economic models
        <xref ref-type="bibr" rid="ref4">(Dhami 2016)</xref>
        that would consider the financial risks and
outcomes of certain decisions and the social values and costs
of a community-based business. Thus, we anticipate being
able to simulate possible financial outcomes based not only
on financial and economic factors but on social and cultural
ones.
      </p>
      <p>Helping small business owners better manage their
finance through a discovery-driven approach while
providing store credit for their clients are critical possibilities our
project shall create. Community-based finance is a
wellknown practice in local communities that are based on trust
and social relationship (e.g., put on a tab, “fiado” store-credit
in Brazil). Through those financial mechanisms, they can not
only plan their cash flow, but also become eligible for credit
loans with lower-interest-rate and administrative costs. The
advantage for their customers is secure access to store credit
locally. These all help to promote sustainable practices
supported by community-based technology and practices. On
the other hand, banks value the creation of more affordable
forms of credit loans (with lower delinquencies) using
tapping into those local social practices and values, as those
engendered by store credit (e.g., “fiado” ), as informational
“collateral” for microloans.</p>
      <p>At the core of those ideas is the SBOs financial
knowledge about people in their communities. We want to create
mechanisms in which that knowledge is used in the benefit
of the SBOs and their clients and doing so, enact positive
social change. At the same time, we are trying to avoid
designing mechanisms which extract such knowledge and
provide them to other players almost at free cost, as often social
media companies do. This is a fundamental ethical question
which we want our solutions to address, that is, to give back
to the SBOs the actual value of their knowledge.</p>

      <title>Insights from Our Previous Research</title>
      <p>
        In our previous research
        <xref ref-type="bibr" rid="ref2">(Candello et al. 2018)</xref>
        , our
understanding of informal credit’s social and cultural practices
was informed by interviews, work observations, and
analysis of the documentation about the microfinance program
that is publicly available. We conducted semi-structured
interviews and work observations in two cities in the Northeast
of Brazil. The first city was Fortaleza a capital city and an
urban environment. The second city was Icapu´ı, located in the
semi-arid region in the Northeast seafront. We interviewed
SBOs and credit agents from the micro-finance institution
(MFI). All the interviews took place at the local business
establishments in September 2014.
      </p>
      <p>
        We understood that quite naturally, the merchants and
their customers form an important social network. Usually,
the small business is in the same neighborhood where the
merchant and customers live. They meet very often, and
depending on the business (e.g., groceries), the customers
may pass by the small business every day. They may even
‘hang out’ in the spot, as described in
        <xref ref-type="bibr" rid="ref8">(Guimara˜es 2007)</xref>
        .
The “fiado” transactions are ordinary in Brazil
        <xref ref-type="bibr" rid="ref7 ref8 ref9">(Gonzalez
et al. 2013; Guimara˜es 2007; Magalha˜es and Abramovay
2008)</xref>
        . It is an informal credit practice in which merchants
sell products to a customer based on trust that they will pay
for them in the future. The date for repayment of the loan
is variable and informal, e.g. “next week”, “next month”, or
simply “I will pay it later”. The use of “fiado” is a source of
reciprocal tension. It relies on personal trust and good faith.
Moreover, at the same time, it generates a mutual
obligation where the customer is obligated to repay the loan and
continue to shop at the establishment, and the store-owner is
obligated to keep offering store credit. The duality of
informal store credit thus rests on the fact that, on the one hand,
store-owners are compelled to allow customers to use
“fiado” to maintain their customers. On the other, the extent to
which store-owners’ trust that their customers will pay back
their debts creates uneven relationships. In the extreme, the
lack of payment will become a moral barrier and prevent
customers from returning to the shop.
      </p>
      <p>Typically, SBOs take notes in a notebook to remember
their clients’ purchases using “fiado” store credit (see
Figure 1). They also use the notebook to record transactions
where the SBOs had no change available and therefore owe
the customer a small amount of money. Each of our
participants had their own way of taking notes. One, a cake
baker, only documents the delivery day and value of the
purchase and says she always remembers the customer’s
name by heart. Others take notes of customer names,
purchase amounts, and compute summary totals for new
purchases made in the month. As some customers do not pay
the full amount at once, merchants deduct the amount paid
by crossing out the current value and writing down the new
amount owed by them. In general, SBOs are not very
organized with their notebooks, and many times they cannot
find recorded transactions in the current notes. Other times
they only record the customers’ names and do not record the
purchase value. Consequently, the business owners are often
not aware of exactly how much people owe them by week
or month, which impacts their inventory management and
limits their ability to predict future income.</p>
      <p>
        Our observations of the prevalence of informal lending
among small business owners have encouraged us to
envision the possibility of new financial management tools. We
designed a new service that may help business owners
manage, plan, and predict their financial lives
        <xref ref-type="bibr" rid="ref3">(Candello et al.
2016)</xref>
        . The system learns from historical payment trends and
can estimate future transactions. A digital trace of purchase
and “fiado” transactions will be preserved and made
available in a secure way for the merchant to use, e.g., as
evidence of cash flows for future formal loan applications. We
have created a mock-up for a smartphone app based on this
design for consequently planning field tests with SBOs in
Brazil. The system would help the SBOs to act as micro
bankers that would also give small loans (e.g. “fiado” ) to
their final clients. In our future research, we aim to adapt it
to the current context (see Figure 2).

    <sec id="sec-4">
      <title>Reflections on the Financial Practices of SBOs</title>
      <p>Our findings generated several insights and design
opportunities for the workshop discussions, and to shape our future
research activities:
1. There is an opportunity for digitization of financial
information to help with account and inventory management.
Observing how the SBOs take notes, which notes they
claim to be more important, and researching client habits
and account management may inspire designers to mimic
those sequences of actions in digital environments.
Financial modelling, if part of the design problem, needs to be
done in a way that is easily understood and financial
assumptions made transparent to the SBOs.</p>
      <p>The SBO in our study were often not happy selling their
products using “fiado” as their customers do not always
pay their debts back. In those cases, the merchants should
contact the customers to demand repayment or in some
cases even cease doing business with them. These impose
great financial as well as social hardships to their
businesses. For one, merchants face difficulties both in
managing the portfolio of small loans and in anticipating
future cash flows from “fiado” repayments. Merchants who
we interviewed asserted that they carry out such loans to
please their customers, to build up loyalty, and friendship.
It is always a difficult social situation when a customer
is unable to fully pay for the all the products she wants.
Thus they may allow “fiado” as a store credit. But, on the
other hand, store owners have troubles when their
customers fail to pay back. In some stores, owners in fact
select carefully which of their customers with whom they
carry out this form of transaction.
2. Informal credit repayments constitute a potential future
cash flow to the small business. The SBOs usually do not
see “fiado” as a positive practice; they would prefer to
receive the money on the same day rather than an uncertain
day of payment. But providing credit to good customers
is a sound financial practice for business since it grows
the clientele and guarantees future cash flow. Therefore,
design technologies which might help the SBOs interpret
“fiado” in a positive way as future cash flow may support
business growth. Additionally, SBOs know their clients
better than the banks and this source of information can
be valuable to banks (e.g. evaluating new and current
customers for new loans).
3. Informal credit (“fiado”) is important to retain customer
although constituting a repayment risk for the SBO. The
close trusted relationships in those communities are what
enable certain kinds of financial practices to exist. Great
care must be taken in designing new technologically
assisted products and services so that the sense of
community remains intact. The design challenge is to support the
development and maintenance of trusted relationships and
generalized reciprocity.</p>
    </sec>
    <sec id="sec-5">
      <title>Current Research</title>
      <p>We are setting our current research in two contexts, the
US and Brazil, and possibly working with financial
institutions and representatives of those communities as partners.
First, we will carry out deep-dive fieldwork to better
understand pre-selected communities’ financial practices in both
regions. To this end, we aim to work with local
communitybased organizations or institutions and academic partners to
facilitate access to the field and local SBOs and carry out the
actual fieldwork. It will allow us to gain a more nuanced
understanding of how SBOs actually manage their finances and
the relationship between their business and local clients and
other local businesses currently. Moreover, we aim to
identify critical data sources and key determining factors that can
better represent and model the SB and local communities’
intrinsic financial dynamics.</p>
      <p>This brief description of the business and social milieu
in which small business practices unfold and business
owners and their clients establish and maintain (professional and
often personal) relationships reveals the complex and
often problematic relationship people have with their personal
and business finances. Micro and small businesses’ financial
practices lie in a complex web of local and personal
relationships, hardship and turn-around experiences, finance and
business education, money availability, and the like.
Unwittingly, those business owners should deal with not only
complex sets of finance concepts and practices (such as future
cash-flows, store-credits, or interest rates) but complicated
and often conflicting decisions (e.g., to allow “fiado” credit,
to ask for repayment, or to cross out a client).</p>
      <p>To design technology to support such practices is by no
means merely a question of financial management – it is not
just about a point of sales or another ease-of-use personal
and business finance management system. It also has to be
about relationship management. It should consider that
business transactions are forms of social and cultural exchanges
and shaped by local moral and cultural norms. For one, the
decision of disallowing a client from purchasing a product
because of bad credit history should be situated in the
context of the social relationships established between the store
owner and its client. It should not be merely unmediated or
just attributed to financial factors (a purely financial
decision). It should be made considering the interplay of all those
factors.</p>
      <p>On the other hand, what does it mean to make such social
practices manifest business practices and become accounted
for? More should be investigated about the complex
relationships between financial practices and local social norms
and morals. They are interdependent.</p>
      <p>Those social practices are the other side of the coin when
discussing the relationships between SBO and their clients
and between SBOs and MFIs. Often, people get trapped in
negative credit spirals as they find themselves borrowing
more money (payday or fiado loans, to be paid back when
one’s paycheck arrives) to cover the existing debt. In such
situations, they tend to lack the mental “surplus” to make
decisions, which will result in more positive long-term benefits
rather than just short-term fixes. In such circumstances,
anticipating such scenarios and attempting to remediate them
early enough might be the best ways to enable individuals to
manage their financial life.</p>
    </sec>

      <title>Final Remarks</title>
      <p>The unfortunate events of 2020 seem to have pushed the
opportunities to deploy and test the idea of microbanking in
many ways. The pandemic forced many people, including
from poor communities, to scramble for forms of Internet
access. At the same time, high levels of unemployment and
their impact on small business owners, particular from the
service sector, have strengthened the need for credit.</p>
      <p>Microbanking can become the way out of this scenario
for many communities, but first we need to address the
complex questions and issues discussed before to guide better
the design of the solutions. In particular, there are difficult
ethical issues, particularly of an adequate reward for the use
of knowledge, which need to be well understood and dealt
with before deployment of actual and scaled solutions.</p>
      <p>In this spirit, we aim to have insightful discussions with
workshop participants and learn more about how AI
technologies can include underrepresented communities and
empower them; and how our ideas, particularly microbanking,
can be safely and ethnically brought to poor and minority
communities.</p>
