This document provides an overview of game theory. It defines game theory as the study of how people interact and make decisions strategically, taking into account that each person's actions impact others. It discusses the history and key concepts of game theory, including players, strategies, payoffs, assumptions of rationality and perfect information. It provides examples of zero-sum and non-zero-sum games like the Prisoner's Dilemma. The document is intended to introduce game theory and its basic elements.
This presentation is an attempt to introduce Game Theory in one session. It's suitable for undergraduates. In practice, it's best used as a taster since only a portion of the material can be covered in an hour - topics can be chosen according to the interests of the class.

Prisoner's Dilemma is a paradox in decision analysis in which two individuals acting in their own best interest pursue a course of action that does not result in the ideal outcome. The typical prisoner's dilemma is set up in such a way that both parties choose to protect themselves at the expense of the other participant. As a result of following a purely logical thought process to help oneself, both participants find themselves in a worse state than if they had cooperated with each other in the decision-making process.
In this session, we will be looking at The Prisoner's Dilemma and how it affects our decision making, group and team dynamics, business decisions. We'll look at real world case studies and nature with a goal of understanding this dilemma better.

3.3 Game TheoryGame theory is a branch of applied mathematics, w.docxgilbertkpeters11344
3.3 Game Theory
Game theory is a branch of applied mathematics, which deals with multi-person decision making situations. The basic assumption is that the decision makers pursue some well-defined objectives and take into account their knowledge or expectations of the other decision makers’ behavior. Many applications of game theory are related to economics, but it has been applied to numerous fields ranging from law enforcement [19] to voting decisions in European Union [20].
There are two main ways to capitalize game theory. It can be used to analyze existing systems or it can be used as a tool when designing new systems. Existing systems can be modeled as games. The models can be used to study the properties of the systems. For example, it is possible to analyze the effect of different kind of users on the system. The other approach is implementation theory, which is used when designing a new system. Instead of fixing a game and analyzing its outcome, the desired outcome is fixed and a game ending in that outcome is looked for. When a suitable game is discovered, a system fulfilling the properties of the game can be implemented.
Most game theoretical ideas can be presented without mathematics; hence we give only some formal definitions. Also, introduce one classical game, the prisoner’s dilemma which we use to demonstrate the concepts of game theory.
3.3.1 Prisoner’s Dilemma
In the prisoner’s dilemma, two criminals are arrested and charged with a crime. The police do not have enough evidence to convict the suspects, unless at least one confesses. The criminals are in separate cells, thus they are not able to communicate during the process. If neither confesses, they will be convicted of a minor crime and sentenced for one month. The police offer both the criminals a deal. If one confesses and the other does not, the confessing one will be released and the other will be sentenced for 9 months. If both confess, both will be sentenced for six months. The possible actions and corresponding sentences of the criminals are given in Table 3.1.

3.3.2 Assumptions and Definitions
Game: A game consists of players, the possible actions of the players, and consequences of the actions. The players are decision makers, who choose how they act. The actions of the players result in a consequence or outcome. The players try to ensure the best possible consequence according to their preferences.
The preferences of a player can be expressed either with a utility function, which maps every consequence to a real number, or with preference relations, which define the ranking of the consequences. With mild assumptions, a utility function can be constructed if the preference relations of a player are known [21].
Rationality: The most fundamental assumption in game theory is rationality. Rational players are assumed to maximize their payoff. If t.

Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.
If you are looking for a pi coin investor. Then look no further because I have the right one he is a pi vendor (he buy and resell to whales in China). I met him on a crypto conference and ever since I and my friends have sold more than 10k pi coins to him And he bought all and still want more.

what is the future of Pi Network currency.DOT TECH
The future of the Pi cryptocurrency is uncertain, and its success will depend on several factors. Pi is a relatively new cryptocurrency that aims to be user-friendly and accessible to a wide audience. Here are a few key considerations for its future:
Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.
Empowering the Unbanked: The Vital Role of NBFCs in Promoting Financial Inclu...Vighnesh Shashtri
In India, financial inclusion remains a critical challenge, with a significant portion of the population still unbanked. Non-Banking Financial Companies (NBFCs) have emerged as key players in bridging this gap by providing financial services to those often overlooked by traditional banking institutions. This article delves into how NBFCs are fostering financial inclusion and empowering the unbanked.
how can I sell my pi coins for cash in a pi APPDOT TECH
You can't sell your pi coins in the pi network app. because it is not listed yet on any exchange.
The only way you can sell is by trading your pi coins with an investor (a person looking forward to hold massive amounts of pi coins before mainnet launch) .
You don't need to meet the investor directly all the trades are done with a pi vendor/merchant (a person that buys the pi coins from miners and resell it to investors)

What website can I sell pi coins securely.DOT TECH
Currently there are no website or exchange that allow buying or selling of pi coins..
But you can still easily sell pi coins, by reselling it to exchanges/crypto whales interested in holding thousands of pi coins before the mainnet launch.
Who is a pi merchant?
A pi merchant is someone who buys pi coins from miners and resell to these crypto whales and holders of pi..
This is because pi network is not doing any pre-sale. The only way exchanges can get pi is by buying from miners and pi merchants stands in between the miners and the exchanges.
How can I sell my pi coins?
Selling pi coins is really easy, but first you need to migrate to mainnet wallet before you can do that. I will leave the telegram contact of my personal pi merchant to trade with.

2. Game Theory
Game theory is the study of how people interact
and make decisions.
This broad definition applies to most of the social sciences,
but game theory applies mathematical models to this
interaction under the assumption that each person's behavior
impacts the well-being of all other participants in the game.
These models are often quite simplified abstractions of real-
world interactions.
3. History of Game Theory
Game theoretic notions go back thousands of
years
– Talmud and Sun Tzu's writings.
Modern theory credited to John von Neumann
and Oskar Morgenstern 1944.
– Theory of Games and Economic Behavior. In the early
1950s,
John Nash (“A Beautiful Mind” fame)
generalized these results and provided the basis
of the modern field.
4. Meaning of game theory
Game theory is the study of the strategic
interaction among rational players.
The games studied can be quite serious and are
studied in many areas of the natural and social
sciences: military, political and marketing
campaign strategy can be modeled with game
theory, also phenomena in natural science, for
example, in the study of evolutionary biology.
5. Definition of game:-
The interactive situation, specified by the set of
participants, the possible courses of action of each
agent, and the set of all possible utility payoffs, is
called a game; the agents 'playing' a game are called
the players
In a competitive situation the course of action
(alternatives) for each competitor may be either
finite or infinite .A competitive situation will be
called ‘’Game’’ .
6. Basic terms related to game theory
1. Players
2.Strategy.
a. Pure strategy
b. mixed strategy
3. Optimum strategy
4. Value of game
5.Payoff matrix
7. Game theory: assumptions
(1) Each decision maker has available to
him two or more well-specified choices or
sequences of choices.
(2) Every possible combination of plays
available to the players leads to a well-
defined end-state (win, loss, or draw) that
terminates the game.
(3) A specified payoff for each player is
associated with each end-state.
8. Assumption con…
4.Each decision maker has perfect
knowledge of the game and of his
opposition.
(5) All decision makers are rational; that is,
each player, given two alternatives, will
select the one that yields him the greater
payoff
9. Use Of Game Theory
Economists
innovated antitrust policy
auctions of radio spectrum licenses for cell phone
program that matches medical residents to hospitals.
Computer scientists
new software algorithms and routing protocols
Game AI
Military strategists
nuclear policy and notions of strategic deterrence.
Sports coaching staffs
run versus pass or pitch fast balls versus sliders.
Biologists
what species have the greatest likelihood of extinction.
10. Game Theory
For Game Theory, our focus is on games where:
– There are 2 or more players.
– There is some choice of action where strategy matters.
– The game has one or more outcomes, e.g. someone wins,
someone loses.
– The outcome depends on the strategies chosen by all players;
there is strategic interaction.
What does this rule out?
– Games of pure chance, e.g. lotteries, slot machines. (Strategies
don't matter).
– Games without strategic interaction between players, e.g.
Solitaire.
11. Elements of a Game
1. The players
• how many players are there?
• does nature/chance play a role?
2. A complete description of what the players can do –
the set of all possible actions.
3. The information that players have available when
choosing their actions
4. A description of the payoff consequences for each
player for every possible combination of actions
chosen by all players playing the game.
5. A description of all players’ preferences over
payoffs.
12. 12
Types of Game Theory
1. Two-person constant sum game theory
3. Two-person zero sum game theory (e.g., prisoner’s dilemma)
Saddle point
4. Mixed strategy
5. The rectangular game as linear progamming
13. Zero-Sum vs. Non-zero-Sum
In a zero-sum game, a player’s gain is equal
to another player’s loss.
In a non-zero-sum game, a player’s gain is
not necessarily equal to another player’s
loss.
14. Two-Person Zero-Sum Game
Payoff/penalty table (zero-sum table):
– shows “offensive” strategies (in rows) versus
“defensive” strategies (in columns);
gives the gain of row player (loss of column
player), of each poTwo decision makers’ benefits
are completely opposite
i.e., one person’s gain is another person’s loss
– ssible strategy encounter
15. Example 1 (payoff/penalty table
Athlete Manager’s Strategies
Strategies (Column Strategies)
(row strat.) A B C
1 $50,000 $35,000 $30,000
2 $60,000 $40,000 $20,000
16. Two-Person Constant-Sum Game
For any strategy encounter, the row
player’s payoff and the column player’s
payoff add up to a constant C.
It can be converted to a two-person zero-
sum game by subtracting half of the
constant (i.e. 0.5C) from each payoff
17. Example 2 (2-person, constant-sum
During the 8-9pm time slot, two
broadcasting networks are vying for an
audience of 100 million viewers, who
would watch either of the two networks.
18. Payoffs of NW1 for the constant-sum
of 100(million
Network 1 Network 2 (NW2)
(NW1) western Soap Comedy
western 35 15 60
soap 45 58 50
comedy 38 14 70
19. An equivalent zero-sum table
Network 2
Network 1 western Soap Comedy
western -15 -35 10
soap - 5 8 0
comedy -12 -36 20
20. Equilibrium point
• In a two-person zero-sum
game, if there is a payoff value
P such that
P = max{row minimums}
= min{column maximums}
then P is called the equilibrium point, or
saddle point, of the game
21. The Prisoners' Dilemma Game
Two players, prisoners 1, 2.
Each prisoner has two possible actions.
– Prisoner 1: Don't Confess, Confess
– Prisoner 2: Don't Confess, Confess
Players choose actions simultaneously without
knowing the action chosen by the other.
Payoff consequences quantified in prison years.
– If neither confesses, each gets 1 year
– If both confess, each gets 5 years
– If 1 confesses, he goes free and other gets 15 years
Fewer years=greater satisfaction=>higher payoff.
– Prisoner 1 payoff first, followed by prisoner 2 payoff.

24. Prisoners' Dilemma :
Example of Non-Zero Sum Game
A zero-sum game is one in which the players'
interests are in direct conflict, e.g. in football, one
team wins and the other loses; payoffs sum to
zero.
A game is non-zero-sum, if players interests are
not always in direct conflict, so that there are
opportunities for both to gain.
For example, when both players choose Don't
Confess in the Prisoners' Dilemma
25. Prisoners' Dilemma :
Application to other areas
Nuclear arms races.
Dispute Resolution and the decision to hire
a lawyer.
Corruption/political contributions between
contractors and politicians.
