Game Theory within the Coffee Industry of PNG: Kainantu, EHP
Abstract:
Game theory is a useful tool in analyzing strategic interactions among players in the coffee industry of
Papua New Guinea (PNG), particularly in the Kainantu area of the Eastern Highlands Province (EHP). This
paper aims to explore how game theory can shed light on the complex dynamics of the coffee market in
Kainantu, where multiple stakeholders, including farmers, traders, and buyers, compete and cooperate to
achieve their objectives.
The study employs a qualitative research design, using semi-structured interviews and focus group
discussions with key informants in the coffee industry. The data collected are analyzed using game theory
concepts, such as dominant strategy, Nash equilibrium, and prisoner's dilemma, to identify the strategic
behavior of the players in the coffee market.
The findings suggest that the coffee market in Kainantu is characterized by a high level of competition,
particularly among smallholder farmers, who face challenges in accessing credit, inputs, and market
information. Traders and buyers, on the other hand, have more bargaining power and can exploit
information asymmetry to gain an advantage. The study also identifies instances of cooperation, such as
collective marketing and sharing of resources among farmers.
Overall, game theory provides a useful framework for understanding the strategic behavior of players in
the coffee market in Kainantu, highlighting the importance of cooperation and competition in achieving
sustainable development outcomes for the industry.
Introduction
Game theory has become an increasingly important tool in understanding the decision-making process of
individuals and firms operating in different industries. In the coffee industry, game theory can be used to
analyze the interactions between different actors, such as farmers, traders, and processors, and the strategies
they employ to maximize their profits. This research paper aims to apply game theory to the coffee industry
in Kainantu, Eastern Highlands Province (EHP), Papua New Guinea (PNG). Kainantu is known for its highquality coffee, which is exported to various countries, including Australia, New Zealand, Italy, England,
Chine, the United States, and Japan. The coffee industry in Kainantu is characterized by a complex network
of actors, including smallholder farmers, traders, and large-scale processors. The interactions between these
actors are influenced by various factors, such as market conditions, government policies, and social norms.
By using game theory, we can gain insights into the decision-making process of these actors and understand
how their strategies affect the overall performance of the coffee industry in Kainantu.

Overview of the Coffee Industry in PNG and Kainantu.
Challenges facing the Coffee Industry
The coffee industry in Papua New Guinea (PNG), particularly in Kainantu, Eastern Highlands Province
(EHP), faces a number of challenges that hinder its growth and development. Some of the major challenges
include:




Limited infrastructure: Kainantu and the surrounding areas have limited infrastructure, making it
difficult to transport coffee beans from farms to markets. The lack of good roads and transportation
systems results in higher transportation costs and lower profits for farmers and exporters.
Poor quality control: The quality of coffee beans produced in Kainantu and other parts of PNG can
vary greatly due to poor farming practices, inadequate processing, and lack of quality control
measures. This can result in lower prices for coffee beans and make it difficult for exporters to
compete in the global market.
Limited access to finance: Many coffee farmers in Kainantu and other parts of PNG have limited
access to finance, making it difficult for them to invest in their farms, purchase equipment and
inputs, and improve their farming practices.
Lack of government support: The government of PNG has been criticized for not providing enough
support to the coffee industry, particularly in terms of funding research and development, providing
technical assistance, and investing in infrastructure.



Climate change: Climate change is a growing threat to the coffee industry in PNG. Changes in
rainfall patterns, rising temperatures, and more frequent extreme weather events can negatively
impact coffee production, affecting yields and quality.
Low prices: The global market for coffee is highly competitive, and prices for coffee beans can
fluctuate greatly. Coffee farmers in Kainantu and other parts of PNG often receive low prices for
their beans, which makes it difficult for them to make a living and invest in their farms.
Limited market access: PNG faces challenges in accessing global markets due to its remote location,
limited infrastructure, and lack of brand recognition. This can limit opportunities for exporters and
reduce the prices they can fetch for their coffee beans.
Overall, addressing these challenges will require a coordinated effort from stakeholders in the coffee
industry, including the government, farmers, exporters, and other private sector actors. Improving
infrastructure, investing in quality control, increasing access to finance, and developing new markets are

Relevance of Game Theory in the Coffee Industry of PNG.
Game theory is an important tool for analyzing the strategic interactions between different players in the
coffee industry of Papua New Guinea (PNG), particularly in Kainantu, Eastern Highlands Province (EHP).
The coffee industry in Kainantu involves a complex web of interactions between coffee farmers, middlemen,
exporters, and buyers, each with their own goals and strategies.
Game theory provides an understanding how these different stakeholders interact and make decisions. By
modeling the strategic interactions between players, game theory can help identify the optimal strategies
for each player and predict the likely outcomes of their interactions.
In the coffee industry of Kainantu, game theory can be used to analyze a range of issues, including pricing
strategies, supply chain management, quality control, and market access. For example, game theory can be
used to analyze how different pricing strategies might affect the behavior of coffee farmers, middlemen,
and exporters, and to identify pricing strategies that can lead to more efficient and profitable outcomes for
all players involved.
Game theory can also help identify opportunities for cooperation and coordination between different
stakeholders in the coffee industry. For example, by modeling the interactions between coffee farmers and
middlemen, game theory can help identify ways to improve the quality of coffee beans, reduce transaction
costs, and increase profits for all parties involved.
Furthermore, game theory can help identify the factors that drive decision-making in the coffee industry,
such as information asymmetry and market power. By identifying these factors, game theory can help
inform policy decisions and industry interventions that can improve the efficiency and sustainability of the
coffee industry in Kainantu and PNG as a whole.
Game theory is a valuable tool for analyzing the complex strategic interactions between different
stakeholders in the coffee industry of Kainantu, EHP, and PNG as a whole. By providing insights into
decision-making, pricing strategies, and supply chain management, game theory can help stakeholders
identify opportunities for cooperation and coordination, improve the quality and value of coffee beans, and

1.3.
The application of Game Theory in the Coffee Industry of Kainantu
Game theory is a mathematical framework that models strategic interactions between decision-makers. It
provides a way to analyze and understand the behavior of individuals or groups in situations where the
outcome depends on the choices of multiple parties. In Kainantu, Eastern Highlands Province (EHP) of
Papua New Guinea (PNG), game theory can be used to analyze the interactions between different
stakeholders, such as coffee farmers, exporters, and buyers, and to identify strategies that can benefit each
party.
Game theory can be applied to understand the strategic interactions between coffee farmers, middlemen,
and exporters. For example, coffee farmers may choose to sell their coffee beans directly to exporters or to
middlemen who then sell the coffee to exporters. The exporters, in turn, may choose to buy from the farmers
directly or through middlemen. Each party's choice depends on factors such as the price offered, the quality
of the coffee beans, and the reliability of the other parties.
It can be used to analyze the different strategies that each party can adopt and to identify the Nash
equilibrium, which is the set of strategies where no player has an incentive to deviate from their chosen
strategy. For example, in a scenario where middlemen offer higher prices to coffee farmers than exporters,
and exporters have limited information about the quality of coffee beans, a Nash equilibrium may be
reached where most farmers sell their coffee beans to middlemen, who then sell the coffee to exporters.
However, game theory can also identify situations where there is a potential for cooperation among players,
which can result in better outcomes for all parties. For example, if exporters provide information about the
quality of coffee beans to middlemen, the middlemen can make more informed decisions about which
coffee beans to buy from farmers, which can improve the quality of coffee beans and benefit all parties in
the supply chain.
Overall, game theory can provide valuable insights into the strategic interactions between different
stakeholders in the coffee industry of Kainantu, EHP, PNG. By analyzing the different strategies that each
party can adopt and identifying the Nash equilibrium and potential for cooperation, game theory can help
stakeholders identify ways to improve the efficiency and effectiveness of the supply chain and achieve
better outcomes for all parties involved

Data and Analysis
During the qualitative data collection phase of the research, interviews were conducted with key
stakeholders in the industry in various locations including Obura, Gasup, Tairora, Aiyura, Bonta, and
Tirokave. The stakeholders interviewed included coffee farmers, middlemen, exporters, and buyers, as well
as representatives from local government and industry experts.
The interviews revealed that the coffee industry in these areas is facing numerous challenges, including low
productivity, poor infrastructure, inadequate access to finance, and limited market access. Many coffee
farmers cited the high cost of production as a major challenge, as they struggle to afford inputs such as
fertilizers, pesticides, and labor. As a result, many farmers are unable to increase their yields or improve
the quality of their coffee.
Furthermore, the interviews revealed that there is intense competition between coffee companies in the
region, including Colbran Coffeelands, Gabiga, KCF, Yarai, Akau, and Arokara. These companies compete
for access to coffee beans, and also compete with each other in the export market. This competition often
leads to price undercutting and other aggressive tactics, which can harm the sustainability of the industry
as a whole.
Despite these challenges, the stakeholders expressed optimism about the potential for game theory to
improve the industry. Many believed that by using game theory models, it would be possible to identify
potential strategies for addressing the challenges facing the industry, such as improving access to finance,
developing better infrastructure, and increasing market access. By analyzing the strategic interactions
between different stakeholders, game theory could also help to identify potential solutions to the problem
of price undercutting and other forms of competition.
