Abstract
This study aims to investigate the pricing practice of bubble tea market in Bangkok.
Different brands can charge different prices for one glass of bubble tea. So the paper observes
basic information from 22 brands of bubble tea. SCP framework is introduced to demonstrate
and analyze the market. To strengthen the analysis, 230 samples were surveyed about the
bubble tea purchasing decision and preference. According to product differentiation criteria,
the paper categorizes product into three types. The result indicates that product differentiation
has an effect on prices differently according to the types of bubble tea market. In other words,
General tea charges the lowest price with franchise strategy. Tea with special topping
launches a new product as much as possible. Premium tea charges the highest price with
quality strategy. Interestingly, Tea with special topping category gains the highest popularity
even the price is higher than General tea category.
1. Introduction
Due to the hot climate in Thailand, nothing is better than a sweetness and refreshment
of bubble tea. A smell of tea with chewy tapioca balls can attract many customers to try this
tasty drink. Nowadays, a lot of bubble tea shops are popping up throughout Bangkok.
Consumers easily find bubble tea shops in crowded areas such as department store, Central
Business District (CBD area), BTS Skytrain, and etc. Since bubble tea became popular for
the past few years, customers need to wait long queue for some brands. Many photos and
reviews of the popular brand are posted on social media. Some brands stay ahead from their
For the basic recipe, bubble tea consists of iced tea, milk, sugar and tapioca balls.
However, if you try to observe the price, one glass of bubble tea has the different price ranges
for the different brands. Some brands charge price up to 130 baht per glass while others
charge only 25 baht. The highest observable price of bubble tea on this paper can buy a good
meal in a restaurant. This wide gap of bubble tea price leads to the main question of this
paper: What accounts for the difference in price of bubble teas in Bangkok?
According to the wide range of price, this paper attempts to observe and understand
the price of bubble tea market and also analyze the reason behind each strategy by taking
product differentiation into consideration. Various strategies of each brand provide different
market power and degree of competition. Hence, with more understanding of firm’s strategy,
it tends to be valuable information to beverage industry in Thailand and investors who want
literature review. Then, the paper explains the background of bubble tea industry. The next
section demonstrates economic theory and methodology that adopted in this paper. Lastly,
this paper analyzes the results and summarize our finding and implications.
2. Literature review
Law of one price rarely exists in the real world situation. According to Sorensen
(2000), “Homogeneous goods are often sold at widely different prices by rival firms, even in
consider products or brands of a various firm to be imperfect substitutes. Although bubble tea
has the similar characteristic in the market, different brands can charge different prices for
one glass of bubble tea. When looking at the characteristic of bubble tea market, it follows
There are many works that link price strategy with location. Many authors (e.g.
Gannon, 1997; Steward and Davis, 2005) point out that products at different locations must
be treated as different. The basic logic of Hotelling clearly extends to encompass product
differentiation in a market that is spatially distributed. We can notice that price of bubble tea
in CBD or urban area is different from school or suburb area. Copeland (1940) has been
suggested that potential new seller, in considering where to locate, will have to consider not
only the number of buyers who might be moved to a prospective location but also the ease or
packaging, and advertising image can affect price strategy of each firm (Gannon, 1997). Dana
and Fong (2011) stated that competition creates an incentive for the firm to maintain their
market share by competing in product’s quality. Gregory (1948) is linked with Dana and
Fong (2011) research. He found that if there were many sellers of a fairly standardized and
stable commodity, sellers' rivalry would take the form of price cuts or improved quality or
market. The research showed that consumers have various needs and tastes for quality. Some
consumers prefer to buy a low-quality product. Whereas others can afford and prefer to buy a
high-quality product. “In the symmetric equilibrium, firms use mixed strategies that
randomize both price and quality, and obtain strictly positive profits” (Chioveanu, 2012).
When the true quality of a product is not known before purchase, consumers may rely
on a firm's reputation to form expectations of the product's quality. In this case, product
prices will depend on firm reputation, as shown by Klein and Leffler (1981), Shapiro (1983),
and Allen (1984). Since bubble tea is an experienced product, consumer relies on the
reputation of the brand. There is empirical evidence that collective reputation is an important
factor in determining price premiums. Landon and Smith (1998) used data from Bordeaux
wines to estimate the effect of current product quality and reputation on price. The study
demonstrated that reputation is an integral factor in determining price premiums for wine.
Quagrainie, McCluskey, and Loureiro also found that a common reputation exists and has a
positive effect on the price of Washington apples relative to apples from other.
Since bubble tea is invented from Taiwan, brands from the origin can charge a higher
price and perceived higher quality than the local brand. Eckhardt (2005) found that Indian
consumers perceived a local pizza brand as foreign because the product category's perceived
perceived as foreign, such as pizza in India and coffee in China, are more likely to benefit
from perceived brand globalness. Moreover, Steenkamp, Batra and, Alden (2003) research
use consumer data from the U.S.A. and Korea. They found that perceived brand globalness is
positively related to both perceived brand quality and prestige and, purchase likelihood.
Besides, perceived brand globalness may provide a significant source of competitive strength:
the higher a brand's perceived globalness, the higher its perceived quality, prestige, and
purchase likelihood. Perceived quality and prestige cannot be readily copied, and hence
3. Industry background
Bubble tea is a tea-based drink (e.g. black tea, green tea, milk tea, and fruit tea) served
with chewy tapioca balls. It is also known as boba tea, pearl tea, tapioca tea, and many other
names. This drink is originated from Taichung, Taiwan. In the late 1990s, bubble tea became
a popular drink in most parts of Asia and well received by global consumers from Canada,
For Thailand, Mr.shake was the first brand that enters this market since 1999. The
popularity of bubble tea attracts many sellers such as Orient station, QQ house, Snow pop,
and etc. Nowadays, these brands disappeared from the market except Mr.shake because of the
high degree of competition. Although Mr.shake still gain popularity because of first-mover
Due to sweetness and hot climate in Thailand, bubble tea has become one of the
favorite drinks for Thai consumers. Many bubble tea shops are popping up throughout the
city in Thailand especially in Bangkok. Consumers easily found bubble tea shops in different
locations such as office building, university, department store, and BTS Skytrain. Different
brands of bubble tea in Thailand are owned by the local and multinational company. They use
different strategies, different quality, and different recipe to compete in the market. Some
sellers introduce high price with the premium ingredient, while others sell cheaper price and
reduce quality to gain some market share. Furthermore, many sellers try to create the wide
range of menus and ingredients to differentiate themselves from other brands and satisfy
customer needs.
4. Theoretical framework
SCP-paradigm. This framework explains the relationship between market structure, market
conduct, and market performance. Since we need to understand the market characteristics and
interaction of bubble tea industry, we will go through the market structure, conduct, and
performance respectively.
The first element of this framework is a market structure which determines the
character and competitiveness of the market. There are many common measurements in this
element. So this paper mainly focuses on analyzing product differentiation. The criteria will
be used to categorize the type of bubble tea market. “If consumers believe that the products
differ and shop accordingly, then the products are effectively differentiated” (Carlton and
Perloff, 2005). Since consumers have the variety of preferences, product differentiation can
distinguish one product from another and create a competitive advantage for that brand.
To extend the meaning of product differentiation, this paper also applies Salop’s
circular model to analyze the bubble tea market. “All firms that offer the differentiated goods
are located on a circle with equal distance” (Policonomics, 2012). Consumers will purchase
the products that closed to their preference by considering both differentiated products
(variety brands of bubble tea) and undifferentiated products from another industry (outside
options such as soft drink, fruit juice, and coffee). Thus, this theory will be adopted to support
and interpret the relationship between customer’s preferences and product differentiation
scheme.
Secondly, market conduct is influenced by the market structure. The conduct can be
determined by pricing strategies, quality choice, advertising strategies, R&D, and franchise.
Since this research classifies the product by product differentiation, the strategy that each
brand used will depend on market conduct in the earlier part. So the detail in market conduct
structure and conduct. Market Performance indicates market power or ability to charge price
over the marginal cost. In order to measure the degree of market competition, there are two
different measurements which are a rate of return (profits earned per dollar of investment)
and price-cost margin (the difference between price and marginal cost). So this paper will
focus on price-cost margin to analyze the competition in the market, whether it is perfect
5. Methodology
To see the linkage between the degree of competition, strategy, and market power of
each firm, SCP framework is an appropriate tool to understand the market and answer the
main question of this paper. As a result, this paper uses SCP-paradigm as the main
framework and relies on primary data collection of pricing in bubble tea market. I observe 22
popular brands of bubble tea by looking at the number of branches, types of tea, the variety of
menus and sizes to analyze the pricing scheme. This paper gathers the data based on my
the paper analyze the behavior of each type along with the price range. From all analyses, I
decide to explore the reason behind why each type charges at that specific amount and why
In order to support the interpretation about competition level in bubble tea market,
there will be a total number of 230 surveys self-administered questionnaires related to bubble
tea purchasing conducted to customer’s side. The first part would be a multiple choice related
to factors that affect bubble tea purchasing, brand preferences and reason, and quality of
bubble tea in each brand. The second section of the questionnaire related to demographic
questions including age, gender, income level and education level. Moreover, there are
questions about socio-economic status such as free time activity and frequency of going to
the department store to reflect consumption pattern and lifestyle for each group of customers.
After that, a descriptive analysis would be used as data analysis approach to the
demographic and socio-economic status of the respondents in the first place. Then, the
analysis will be conducted pass through the SCP paradigm as it has been written in a
theoretical framework.
6. Result
Generally, bubble tea consists of a tea base mixed with milk and fruit and served with
tapioca balls. However, different brands provide different types of bubble tea with different
price ranges. Therefore, this paper attempts to categorize bubble tea into three types by using

The first category is General tea. Types of tea are used as criteria for differentiated
products. Brands that positioned in this type will provide milk tea, green tea, black tea, and
fruit tea served with tapioca balls. In other words, most of bubble tea brands will provide
these tea drinks on their menus. Some brands offer only bubble milk tea while other brands
The second type is Tea with special topping. This category is differentiated by
topping and premium ingredients. Since there are many brands of bubble tea in the market,
brands of this type provide additional toppings such as golden bubble, cheese, Hokkaido
milk, and macchiato. The paper mainly focuses on 6 well-known brands; KOI The, Kamu,
Fuku matcha, Dakasi, Coco, and Osaka milk tea. To attract customers, location is an
important factor. These brands mostly located in the crowded area such as office building,
The last category is Premium tea. The producer sells premium tea that other brands do
not have such as Earl Grey tea, Uji matcha tea, and Hojicha tea with golden bubble. So the
type of tea, topping, premium ingredient, location, and uniqueness are the criteria for this
type. This paper included two brands in this category which are Nomimono and ATM tea bar.
The process of bubble tea is visibly shown to customers. Brands demonstrate that they use
premium ingredient instead of artificial one with hygiene and meticulousness. The product
can be made to order for each customer such as sweet adjustment, a richness of tea, and
additional topping. Moreover, both of the brands are located in high income and crowded
with no endpoints while each triangular shows all brands of bubble tea market in this paper.
From Salop’s circular model, the seller of each category sets price by taking the number of
brands into account. “That is, the further away other stores are from your store, the greater the
market power you have to the customers located near your store” (Carlton and Perloff, 2005).
For instance, Premium tea is considered as monopoly region since there are only 2 firms in
the market. On the other hand, brands in General tea (competitive region) are located closer
together and compete for the same consumers. So it easier to lose customers to two its nearest
rivals.
The paper uses the result from the survey to construct customer’s characteristic and
support the analysis. From Appendix 2, more than half of the respondents are female who get
income lower than 15,000 baht and age between 19-23. Furthermore, there is a question
about frequency of going to department store which imply socio-economic status. I divided
customer into three groups by using types of department store as a criteria. Customers who
mostly go to Paragon, Emquartier, Emporium, and Central World are categorized in grade A
customers. The Central group is classified as grade B customers. Lastly, customers who go to
The mall, Lotus, and Big-c are grade C customers. The table in appendix 2 shows that most
From considering bubble tea characteristics, there are a lot of competitors in this
market. We can see bubble tea shops throughout Bangkok. The barrier to entry in this market
is considered to be low since producers do not need a huge amount of money to invest and no
special licensed needed. Although this market looks familiar to perfect competition, products
In case of bubble tea market, a product can be differentiated by type of tea, topping,
premium ingredient, location, and uniqueness. Each category has different factors in product
differentiation. Besides, these factors are consistent with the survey of customer side.
From the survey, there are many factors that affect consumer purchasing. (Figure 2).
Consumers will purchase a drink that closed to their preference. Taste and quality are the
most significant factors that affect customer purchasing. Customers consider good taste and
good quality of bubble tea with reasonable price. In addition, consumers also take location
into account. Many opinions from customer indicate that they not willing to buy bubble tea
that far away from their home even that brand has high a reputation. In other words, cost and
time of transportation may affect the purchasing decision. Therefore, we can notice that many
brands try to extend their branches to attract customers. Some brands are located in high
populated to gain higher market share. Additionally, I classified the respondents into three
levels of socioeconomic status (Appendix 3). The result also demonstrates that taste, quality,
preference toward bubble tea, and location are the most important factors that customers
considered.

6.4 Market conduct and performance (strategy and market power for each type)
Since the paper uses product differentiation as a criteria to categorize the type of
bubble tea, this section will separately explain strategy and performance of each type.

The paper considers 16 brands in the market (Table 2). The perceived quality of
customer side is medium to low (Appendix 4, category 1). The number of branches varies
from 5 to 39. So I approximately calculate the number of branches to analyze the market
share1. Since there are many competitors in this market, general tea can charge the lowest
price. The average price is around 42.5 baht. The price also affects the location of brand. Due
to a low price, brands in this category are located in various locations such as hypermarket,
gas station, department store and school/university area to match with their target market.
Mostly, brands in this category use franchise strategy to compete in the market. The
percentage of sales to franchisors, while franchisee gets initial training, a trademark license,
raw materials, operation manuals, and etc. in return. Sellers expand the number of branches
as much as they can to attract customers and gain market share instead of competing with
price. For instance, Ochaya and Pearly tea have the highest number of branches in this
observation which are 39 and 35 respectively. Bubble republic is another interesting example.
This brand has strong distribution system by selling products through Family Mart, 7-eleven,
Tops, and Villa market. This will facilitate the product's reach into its target market. Some
brands such as Monkey shake and Kin Cha have only five branches in Bangkok but they have
a lot of branches in many provinces in Thailand. That is to say, each brand has the different
The market for General tea is considered to be competitive because there are a lot of
sellers and buyers in this market. Sellers do not have the power to set price since they need to
follow franchise’s regulation. Although most of the brands use artificial ingredients to lower
the cost of production, the price charged is still low when comparing to other categories.
Namely, General tea market has the lowest market power to charge price over marginal cost.

The average number of branch excludes Chamiji and Bubble republic to avoid overestimation. Chamiji has
approximately 100 branches in Bangkok and 600 branches in Thailand. Bubble republic has approximately 200
branches in Bangkok and 400 branches in Thailand.

The second category is Tea with special topping by considering six well-known
brands (Table 3). Osaka milk tea is only one brand that owned by Thai people while the
remaining brands are owned by multinational companies such as Taiwan and Japan. The
perceived quality from the customer perspective is considered to be high to medium due to
the origin of the brand (Appendix 4, category 2). The number of branches varies from 1 to 25.
To stay ahead of high competition market, these brands try to differentiate their
products and attract customers attention by providing special topping that General brand does
not have. Although the average number of branches is the same with the first category, the
average price of this market is higher than the first category more than double. This strategy
may help sellers in this market to gain more market share or profit and survive in this market.
In addition, this strategy is linked with Salop’ circular model. Customer will choose the
product closed to their preference. As a result, sellers in this category try to differentiate the
products to attract the customer and to satisfy their need since the customer has the different
preference.
The number of buyers in this category is high when considering popularity from
figure 3. KOI the and Kamu gain the highest popularity even though the price is higher than
the first category. On the other hand, there are only six brands that provided this type of
product. Since the market has high demand and low supply, it implies that market has a lower
level of competition than the first category which leads to higher market power.
When classified the respondents into three levels of socioeconomic status, it implies
that different grade of customers have different preferences. Appendix 5 demonstrates that
more than half of grade A and B customers prefer brands in Tea with special topping
category. Whereas the most popular category of grade C customer is General tea.
Interestingly, Premium tea category only gain popularity from grade A customer.

In case of Premium tea category, it consists only two brands in this observation (Table

qualities of goods produced in the market in order to extract consumer surplus” (Carlton and
Perloff, 2005). From the observation, the strategy of both brands is quality choice. They need
to apply this strategy to maintain quality in the whole supply chain. That’s why the average
branch is only one and located in a high-income area to match with high price strategy.
This category can view as duopoly market since they can charge the highest price
with the lowest number of branches. There are fewer buyers and sellers in premium tea
market which imply a low degree of competition. From Appendix 5, Most of target customers
are in Grade A which only count for 11 percent. Namely, some consumers are willing to pay
even though the price is high. Furthermore, brands face high cost because they have to use
premium ingredients such as brewed tea and fresh milk. However, they get a lot of profit
because they charge consumers at the high price. It is found that there is high margin, saying
a lot of difference between price and marginal cost. This means the sellers have a high degree
of market power. Hence, they are able to charge prices a lot higher than cost.

Apart from product differentiation, loyalty program creates an incentive for customers
to repurchase the product and increases market power. Punch card commonly uses in bubble
tea market. Customers get a stamp for every bubble tea they buy. However, every brand not
From table 5, six brands do not have this program because of different reasons. Both
brands in Premium tea can view as the high-end product. The loyalty program can devalue
brand image and decrease profit because they use the premium ingredient in a production
process. Moreover, the target market for this category has high willingness to pay. So brands
can ignore this program and focus more on improving quality rather than promotion. Osaka
milk tea has a similar situation with Premium tea. Whereas Bubble republic and Chamiji have
more than 400 branches in Thailand. Many individual owners and variety of distribution
channels through FamilyMart and 7-Eleven create less incentive for brands to use the
program since they can gain market power by expanding the number of branches.
Interestingly, although Mr.shake charges low price with the low number of branch, a brand
still gain high popularity from customers because of first-mover advantage without applying
for a loyalty program. From figure 3, Mr.shake gains the highest popularity in General tea
7. Conclusion
strategy by introducing the case of bubble tea market in Bangkok as an example. According
to product differentiation criteria, we can categorize bubble tea market into 3 types; General
tea, Tea with special topping, and Premium tea. Our finding demonstrates that each type has
For General tea, brands use franchise strategy and expand the number of branches to
compete in the market because there are a lot of sellers and buyers in this market. It implies a
high degree of competition in the first category. In case of Tea with special topping, brands in
this category try to differentiate their product as much as possible to gain market power. The
high number of demand and less number of supply indicate the lower level of competition
when compared to General tea category. Lastly, the market for Premium tea is less
competitive when considering the number of seller and buyer. They use quality strategy
rather than quantity strategy to gain market power. This strategy describes the reason why
brands can charge the highest price with the lowest number of branches.
As a consequence, the strategies are different for each type since each brand has the
different level of market power, behavior, and the number of supply and demand in the
market.
8. Limitation and further improvement
This study demonstrates the result of the strategy that has been adopted by most
brands of bubble tea in Bangkok. However, the paper only focuses on well-known brands.
There are many small brands and brands in other provinces that the paper does not include.
Moreover, this paper approximately estimates marginal cost of the brand in each category
since profit and cost are a business secret of the company. Therefore, the further study would
be better to include a number of observations in other provinces and concern more on the
marginal cost. So it could give more insight results about all types of bubble tea market.
