2 LITERATURE REVIEW
With the Literature Review, the author finds that
research on Airbnb is mostly focusing on travelling
tourism, such as customers' optional motivation,
development of hotel business, impact on tourist
destinations, etc. Some studies in the Economics
aspect include pricing factors and local revenues
affected by Airbnb. However, in these discussions
from an economic perspective, a key issue has been
relatively overlooked-Airbnb, as a typical
representative of the sharing economy, lacks
systematic research on the decision-making
mechanism and market impact of its hosts' dynamic
pricing strategies. For example, an empirical analysis
of short-term rental platforms.
Gallego and Ryzin studied on dynamic pricing
problem of inventory within a limited time. They
found that dynamic pricing was more valuable when
the market demand was equivocal (Gallego and
Ryzin, 1994). Victor Araman and René Caldentey
studied how to use dynamic pricing to maximise
long-term average profit (Victor Araman and René
Caldentey, 2009). Gabriel Bitran and René Caldentey
researched pricing models in revenue management
and provided the theoretical basis and practical
guidance for enterprises to formulate pricing
strategies (Gabriel Bitran and René Caldentey, 2003).
Kelly and William concluded that, in consumers'
opinion, price changes within the short term are more
unfair than those in the long term. Moreover, when
consumers get equal or more discounts in business,
the sense of price fairness and purchase satisfaction
rate is higher (Kelly and William, 2006). Georgios
Zervas, Davide Proserpio, and John W. Byers proved
that Airbnb has a great effect on hotel revenue and
different types of hotels are affected to varying
degrees (Georgios Zervas, Davide Proserpio, and
John W. Byers, 2016). Martin Falk and Miriam
Scaglione found that regulations could significantly
affect Airbnb's lease performance (Martin Falk and
Miriam Scaglione, 2024). He, Qiu, and Cheng studied
the effect on labour supply from dynamic pricing on
Uber. They analysed the data from Uber and explored
drivers' responses to dynamic pricing. The results can
be used to study Airbnb's users' response to dynamic
pricing (He, Qiu, and Cheng, 2022). Gallego and
Ryzin prepared the theoretical framework in a
changing market, and Victor Araman and René
Caldentey further extended to maximize long-term
average profits. Theoretical preparation provided
support for deeper and broader research. Later, more
factors like consumer behavior, regulations effect and
supply were taken into consideration.
The research on the impact of dynamic pricing on
Airbnb revenue mainly focuses on technical
application and strategy differences. Machine
learning is used to mimic the progress of dynamic
pricing and provides pricing suggestions. Wang
(2024) highlighted the complexity of Airbnb's
machine learning algorithms, which process
thousands of data points-including historical
bookings, seasonal trends, and competitor prices-to
generate real-time pricing recommendations. A study
on strategy differences shows dynamic pricing on
Airbnb can increase revenue. Kwok and Xie (2019)
compared pricing behaviours between single-
property and multi-property hosts, finding that multi-
property hosts adopting dynamic pricing achieve
significantly higher revenue than fixed-pricing
counterparts. However, there is no study on how
much can dynamic pricing increase revenue.
Moreover, considering that the definition of pricing
method and algorithm are non-public, how to use
limited public data to define dynamic pricing and
fixed pricing is also a worthwhile research aspect.
The author established original data filtering rules and
definition methods. By doing this, a specific number
was calculated to show how dynamic pricing affect
Airbnb's revenue.
3 METHODOLOGY
3.1 Modeling
To analyse the impact of dynamic pricing on Airbnb's
revenue, this article used linear regression to analyse
the pre-processed data. The regression model used
was:
𝑅𝑒𝑣𝑒𝑛𝑢𝑒 = 𝛽
+𝛽
×𝐷𝑦𝑛𝑎𝑚𝑖𝑐
+𝛽
× 𝐼𝑛𝑐𝑜𝑚𝑒 + 𝛽
× 𝑅𝑜𝑜𝑚 𝑡𝑦𝑝𝑒
+𝛽
×
(
𝑅𝑜𝑜𝑚 𝑡𝑦𝑝𝑒 × 𝐷𝑦𝑛𝑎𝑚𝑖𝑐
)
+𝜖
(1)
Independent variable in this equation showed in
Table1.
In the original data, “price” represents daily price
in local currency and “reviews per month” reflects
guests' occupancy rates and feedback. This article
used a review rate of 0.78 to estimate the annual
income of each room. The review rate is from Julia's
research: about 78% of guests leave reviews of their
accommodation. This provides a revenue estimation
that is closer to the actual booking volume. Thus:
𝐸𝑠𝑡𝑖𝑚𝑎𝑡𝑒𝑑 𝐴𝑛𝑛𝑢𝑎𝑙 𝐼𝑛𝑐𝑜𝑚𝑒
= 𝑝𝑟𝑖𝑐𝑒 × 𝑟𝑒𝑣𝑖𝑒𝑤𝑠 𝑝𝑒𝑟 𝑚𝑜𝑛𝑡ℎ × 12/78
