Abstract (2. Language):
Purpose: The purpose of this paper is to help business marketers with offline channels to
make decisions on whether to sell through Group-buying (GB) websites and how to set online
price with the coordination of maximum deal size on GB websites.
Design/methodology/approach: Considering the deal structure of GB websites especially
for the service fee and minimum deal size limit required by GB websites, advertising effect of
selling on GB websites, and interaction between online and offline markets, an analytical model
is built to derive optimal online price and maximum deal size for sellers selling through GB
website.
This paper aims to answer four research questions: (1) How to make a decision on maximum
deal size with coordination of the deal price? (2) Will selling on GB websites always be better
than staying with offline channel only? (3) What kind of products is more appropriate to sell on
GB website? (4) How could GB website operator induce sellers to offer deep discount in GB
deals?
Findings: This paper obtains optimal strategies for sellers selling on GB website and finds that:
Even if a seller has sufficient capacity, he/she may still set a maximum deal size on the GB deal
to take advantage of Advertisement with Limited Availability (ALA) effect; Selling through GB
website may not bring a higher profit than selling only through offline channel when a GB site
only has a small consumer base and/or if there is a big overlap between the online and offline markets; Low margin products are more suitable for being sold online with ALA strategies (LPALA
or HP-ALA) than high margin ones; A GB site operator could set a small minimum deal
size to induce deep discounts from the sellers selling through GB deals.
Research limitations/implications: The present study assumed that the demand function is
determinate and linear. It will be interesting to study how stochastic demand and a more general
demand function affect the optimal strategies.
Practical implications: This paper provides a very useful model framework and optimal
strategies for sellers’ selling on GB website. It takes advantage of the analytical model to explain
much typical practical phenomenon for E-commerce like free sale with limited availability and
so forth. It also helps GB website operator to induce deep discount from sellers.
Originality/value: This paper is a first attempt to examine the seller's GB sale decision
problem regarding to price and bounds on deal sizes. It analyses how the minimum deal size set
by the GB website affect the optimal decision of sellers’. Moreover, it also discusses the impact
of the interactions between online and offline markets on sellers’ decision.
