Abstract | Both existing customer retention and new customer acquisition are of critical importance to the
growth of the business. Loyal programs and referral programs are usually used to stimulate repeated
purchase and referral engagement. However, the relationship between customers' repeated purchase and
referral behavior is underexplored, and the empirical studies are even rare.
By using a unique empirical dataset that includes the customer's demographic information,
historical purchase, and referral behavior in 2019-2020 from a direct selling company, along with the
COVID-19 data, the first study of this paper examines the impact of the COVID-19 pandemic on direct
sales and whether there are heterogeneous effects of the pandemic on experienced and inexperienced
direct- sellers. By utilizing the difference-in-differences regression research method, the results show an
insignificant impact of COVID-19 on the overall consumption and referral activities of users in this
direct-sales network. However, when decomposing consumption into different product categories, I find
that the consumption for health products increases after COVID-19, where luxury products such as
skincare products will experience an adverse demand shock; for obvious reasons that people have less
need skincare products in times of lockdown. I also find heterogeneous effects of the pandemic on
experienced and inexperienced direct- sellers. Experienced direct-sellers (i.e., the top two quartiles of
users concerning historical consumption amount and/or network size) are purchasing (significantly) less
after COVID-19.
The second study of this paper investigated the factors that influence people’s repeated purchase
and referral behavior and the relationship between consumers’ repeated purchase and referral behavior
by using the data in 2016-2018. This paper also considers the customer’s heterogeneous characteristics
and can distinguish the effect of customer characteristics on both customers’ purchase intention and their
actual purchase behavior. Moreover, this paper not only focuses on pure consumers' behavior but also
pays a lot of attention to the direct sellers (i.e., referrers) who play a significant role in recommending more new customers and motivating more repeat purchases. In the view of direct sellers (i.e., referrers),
this paper also investigated the mutual effect of their repeated purchase and referral behaviors. For each
research question mentioned above, the corresponding research hypotheses are proposed based on
previous literature and the research context of this paper. The econometric regression models are built
and estimated to test the proposed research hypotheses. Before going into the econometric regression
models part (quantitative research method), this paper also uses a qualitative research method (including
literature review and case study) to lay a foundation for understanding the research background.
There are several essential conclusions found in this paper.
(1) Female customers and older customers are more likely to make repeated purchases. But from the
product category view, the two groups of users are found to own heterogenous product preferences.
Female customers are inclined to make purchases in skincare and personal care products. In contrast,
older customers are more likely to purchase health-related products, such as health care and health
supplies.
(2) In terms of the effect of gender and age on customer’s referral probability and actual referral
performance, the results show that female customers and middle-aged customers (around 39-yearold)
are more likely to make referrals.
(3) For the effect of self-reported job on the repeated purchase probability and purchase ability, the
unemployed users are 69% less likely to make a purchase, and the retired users tend to purchase 59
RMB less. In addition, this paper also finds that retired customers are 27.3% less likely to make
referrals.
(4) Age still has a positive and significant effect on the total reward amount, which means the older
customers are more likely to get higher reward amounts by making successful referrals. In addition,
the users who self-reported that they are freelance get more rewards than the baseline group of users.
More interestingly and importantly, the absolute number of recommended users and the total
purchase amounts of invited users are positively significant, revealing that the referral-reward
schema in this research context is very different from the traditional referral-reward programs. The
result shows an additional factor that influences customers' referral behavior – the referral program
reward design. In this research context, both quantity (absolute number of customers recommended
by the referrer) and quality (the consumption-ability of customers recommended by the referrer)
matter for the realization of the reward.
(5) By only focusing on the behaviors of referrers/salespeople in our user sample, this paper finds a
positive effect of repeated purchase on referral and also a positive impact of referral on repeated
purchase.
Understanding the influential factors that play roles in customers’ purchase and referral decisions
is very important for firms. And the identification of the heterogeneous need of their customers helps
make precise customer segmentation and targeting. The positive correlations between customers’
repeated purchase and referral behaviors can provide insights for firms in leveraging on one of the two
past customers' behaviors well and achieving mutual transformation. In summary, this paper offers rich managerial implications about motivating customers’ repeated purchase and referral engagement and
precise customer segmentation and targeting.
