how to swap pi coins to foreign currency withdrawable.DOT TECH
As of my last update, Pi is still in the testing phase and is not tradable on any exchanges.
However, Pi Network has announced plans to launch its Testnet and Mainnet in the future, which may include listing Pi on exchanges.
The current method for selling pi coins involves exchanging them with a pi vendor who purchases pi coins for investment reasons.
If you want to sell your pi coins, reach out to a pi vendor and sell them to anyone looking to sell pi coins from any country around the globe.
Below is the contact information for my personal pi vendor.

Financial Assets: Debit vs Equity Securities.pptxWrito-Finance
financial assets represent claim for future benefit or cash. Financial assets are formed by establishing contracts between participants. These financial assets are used for collection of huge amounts of money for business purposes.
Two major Types: Debt Securities and Equity Securities.
Debt Securities are Also known as fixed-income securities or instruments. The type of assets is formed by establishing contracts between investor and issuer of the asset.
• The first type of Debit securities is BONDS. Bonds are issued by corporations and government (both local and national government).
• The second important type of Debit security is NOTES. Apart from similarities associated with notes and bonds, notes have shorter term maturity.
• The 3rd important type of Debit security is TRESURY BILLS. These securities have short-term ranging from three months, six months, and one year. Issuer of such securities are governments.
• Above discussed debit securities are mostly issued by governments and corporations. CERTIFICATE OF DEPOSITS CDs are issued by Banks and Financial Institutions. Risk factor associated with CDs gets reduced when issued by reputable institutions or Banks.
Following are the risk attached with debt securities: Credit risk, interest rate risk and currency risk
There are no fixed maturity dates in such securities, and asset’s value is determined by company’s performance. There are two major types of equity securities: common stock and preferred stock.
Common Stock: These are simple equity securities and bear no complexities which the preferred stock bears. Holders of such securities or instrument have the voting rights when it comes to select the company’s board of director or the business decisions to be made.
Preferred Stock: Preferred stocks are sometime referred to as hybrid securities, because it contains elements of both debit security and equity security. Preferred stock confers ownership rights to security holder that is why it is equity instrument
<a href="https://www.writofinance.com/equity-securities-features-types-risk/" >Equity securities </a> as a whole is used for capital funding for companies. Companies have multiple expenses to cover. Potential growth of company is required in competitive market. So, these securities are used for capital generation, and then uses it for company’s growth.
Concluding remarks
Both are employed in business. Businesses are often established through debit securities, then what is the need for equity securities. Companies have to cover multiple expenses and expansion of business. They can also use equity instruments for repayment of debits. So, there are multiple uses for securities. As an investor, you need tools for analysis. Investment decisions are made by carefully analyzing the market. For better analysis of the stock market, investors often employ financial analysis of companies.

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.

Rights
• Individuals – have the right to own property and to
pass this property on to their heirs.
• Individuals & businesses – right to earn profits and
to use the profits as they wish, within the constraints
of their society’s law and values.
• Individuals & businesses – right to make decisions
that determine the way the business operates.
• Individuals- right to choose what career to pursue,
where to live, what goods and services to purchase
and more
17. Supply & Demand
Demand : number of goods/services consumers
buy at given price at a specific time
Supply : number of products businesses will sell
at different prices at a specific time
Distribution of resources and products
determined by supply and demand

18. Forces of Supply & Demand
Price at which number of products supplied equal amount of products
consumers are willing to buy at a specific time = equilibrium price

19. Nature of Competition
Pure competition – many small businesses in same product
market (Agri goods). Price is determined solely by supply &
demand.
Monopolistic competition – small number of businesses little
difference in products (Soft drinks). Businesses have some
power over pricing.
Oligopoly– very few businesses selling a product (Airlines
industry). Businesses have full control over pricing.
Monopoly- only one business providing a product (electricity,
nature gas suppliers, business based on patents obtained)
Rivalry among businesses for consumers’
dollars.

rise in prices
•Recession– decline in production, employment,
and income
•Unemployment– % population wants to work
but unable to find jobs
•Depression– unemployment very high;
consumer spending low; business output sharply
reduced
26. Economics - Definitions
• Derived from Greek work oikos (house) and
nomos (custom or law)
• Adam smith (1723-1790) - Father of economics-
“…an enquiry into the nature and causes of the
wealth of nations”
• Alfred Marshall (1842-1924)- “…the study of
mankind in the everyday business of life”
• Lionel Robbins(1898-1984) – “ the science
which studies human behaviour as a relationship
between ends and scare means which have
alternative uses” 29
27. 27
Economics Defined….
•“ as a body of knowledge or study that discusses
how a society tries to solve the human problems of
unlimited wants and scarce resources”
•“ is a Social science since it deals with the society
as a whole and human behaviour in particular, and
studies the production, distribution, and
consumption of goods and services”.
(Study of how individuals and societies deal with
scarcity)
28. 28
Basic Assumptions
• Ceteris Paribus
– Latin phrase
– “With other things (being) the same” or “all other
things being equal”.
• Rationality
– Consumers and producers measure and compare the
costs and benefits of a decision before going ahead.
– Involves making a choice that gives the greatest
benefit relative to cost.
– Firms aim at maximizing profit and minimizing the
cost while consumers aim at maximizing utility and
minimizing sacrifice.
29. 29
Types of Economic Analysis
• Micro and Macro
– Microeconomics (“micro” meaning small): study of the
behaviour of small economic units
• An individual consumer, a seller/ a producer/ a firm, or
a product.
• Focus on basic theories of supply and demand in
individual markets
– Macroeconomics (“macro” meaning large): study
of aggregates.
• Industry as a unit, and not the firm.
• Focus on aggregate demand and aggregate supply,
national income, employment, inflation, etc.
30. 30
Types of Economic Analysis.....
• Positive and Normative
– Positive economics: “what is” in economic matters
• Establishes a cause and effect relationship
between variables.
• Analyzes problems on the basis of facts.
– Normative economics: “what ought to be” in
economic matters.
• Concerned
judgments.
• Incorporates
with questions involving value
value judgments about what the
economy should be like.
31. 31
Types of Economic Analysis....
• Short Run and Long Run
– Short run: Time period not enough for consumers and
producers to adjust completely to any new situation.
• Some inputs are fixed and others are variable
– Long run: Time period long enough for consumers and
producers to adjust to any new situation.
• All inputs are variable
• Decisions to adjust capacity, to introduce a larger
plant or continue with the existing one, to change
product lines.
In terms of accounting or finance:
short run- any time period less than a year
Long run- 5 to 6 years or even as high as 20 years
32. 32
Types of Economic Analysis....
• Partial and General Equilibrium
– Partial equilibrium analysis: Related to
analysis
micro
• Studies the outcome of any policy action in a
single market only.
• Equilibrium of one firm or few firms and not
necessarily the industry or economy.
– General equilibrium: explains economic
phenomena in an economy as a whole.
• State in which all the industries in an economy
are in equilibrium.
• State of full employment
33. 33
Economic Decisions/Questions
The fundamental problem faced by economy :
• WHAT to produce? (make) - Choice
• HOW to Produce?(manufacture) - efficiency
• FOR WHOM to Produce? (who gets
distribution
• Are Resources used economically? – scarcity
• Are resources fully employed?
• Is the economy growing?
what) -
The way these questions are answered, determines the
economic system
34. Economic Principles Relevant to
Managerial Decisions
• Concept of scarcity
– Unlimited human wants
– Limited resources available to satisfy such wants
– Best possible use of resources to get:
• maximum satisfaction (from the point of view of
consumers) or
• maximum output (from the point of view of producers or
firms)
• Concept of opportunity cost
– Opportunity cost is the benefit forgone from the alternative
that is not selected.
– Highlights the capacity of one resource to satisfy multitude of
wants
– Helps in making rational choices in all aspects of business,
since resources are scarce and wants are unlimited 37
35. 35
Economic Principles Relevant to
Managerial Decisions ….
• Concept of margin or increment
– Marginality: a unit increase in cost or revenue or utility.
• Marginal cost: change in Total Cost due to a unit change in output.
MC = TCn – TCn-1
Marginal cost = (Change on total cost)/change in totaloutput
= dTC/ dQ
• Marginal revenue: change in Total Revenue due to a unit change
in sales.
• Marginal utility: change in Total Utility due to a unit change in
consumption.
– Incremental: applied when the changes are in bulk, say
10% increase in sales.
36. Economic Principles Relevant to Managerial
Decisions…
• Discounting Principle
– Time value of money : Value of money depreciates with
time
• A rupee in hand today is worth more than arupee
received tomorrow.
– Outflow and inflow of money and resources at different
points of time
1
PVF = (1 r)n
where
PVF = Present Value of Fund,
n = period (year, etc.)
R = rate of discount 36
37. PVF Example
Example :
Company Z has sold goods to Company M for Rs. 5000.
Company M gave an offer to Company Z that either
Company M pays Rs. 5000 immediately or pay Rs. 5500
after two years. Discounting rate is 8%.
•Now, in order to understand which of either deal is
better i.e. whether Company Z should take Rs. 5000
today or Rs. 5500 after two years.
•we need to calculate a present value of Rs. 5500 on the
current interest rate and then compare it with Rs. 5000.
• if the present value of Rs. 5500 is higher than Rs. 5000,
then it is better for Company Z to take money after two
years otherwise take Rs. 5000 today.
•Result: As present value of Rs. 5500 after two years is
lower than Rs. 5000, it is better for Company Z to take
Rs. 5000 today
38. 38
Production Possibilities Curve
• Shows the different combinations of the quantities of two goods
that can be produced (or consumed) in an economy at any point
of time.
• Depicts the trade off between any two items produced (or
consumed).
• Highlights the concepts of scarcity and opportunity cost
– Indicates the opportunity cost of increasing one item's production (or
consumption) in terms of the units of the other forgone
– Slope of the curve in absolute terms
• Assumptions
– The economy is operating at full employment.
– Factors of production are fixed in supply; they can howeverbe
reallocated among different uses.
– Technology remains the same.

• All points on the PPC (like P and Q) are points of maximum
productive efficiency.
• In the figure, OFp of food and OCp of clothing can be produced
at Point P and OFQ of food and OCQ respectively at point Q,
when production is run efficiently.
• All points inside the frontier are feasible but productively
inefficient.
• All points to the right of (or above) the curve are technically
impossible (or cannot be sustained for long).
• A move from P to Q indicates an increase in the units of
clothing produced and vice versa.
• It also implies a decrease in the units of food produced. This
decrease in the units of food is the opportunity cost of
producing more clothing.

Demand
“If you can’t pay for a thing, don’t buy it. If you can’t get paid for it, don’t
sell it” (Benjamin Franklin)
The process to satisfy human wants/ needs/desires – Demand
Desire: an aspiration to acquire something
Want: having a strong desire for something
Demand: effective desire
Demand is that desire which is backed by willingness and ability to
buy a particular commodity, at a given point of time.
Quantity of the commodity which consumers are willing to buy at a
given price for a particular unit of time.
Things necessary for demand:
Time
Price of the commodity
Amount (or quantity) of the commodity consumers are willing to
purchase at the price
43. Types of Demand
Direct and Derived Demand
Direct demand is for the goods as they are such
as Consumer goods
Derived demand is for the goods which are
demanded to produce some other commodities;
e.g. Capital goods
Recurring and Replacement Demand
Recurring demand is for goods which are
consumed at frequent intervals such as food
items, clothes.
Durables are purchased to be used for a long
period of time (cars, watches, bikes, mobile phones)
Wear and tear over time needs replacement 45
44. Types of Demand….
Complementary and Competing Demand
Some goods are jointly demanded hence are
complementary in nature, e.g. software and
hardware, car and petrol.
Some goods compete with each other for demand
because they are substitutes to each other, e.g.

Individual & Market Demand
Demand for an individual consumer is Individual
demand. Eg. Your demand for Swift car.
Demand by all the consumers for the product know
as Market demand. Eg. Demand for swift in 2015.
Industry demand is the demand for the product by
all firms in the industry. Eg. Demand for car in year
2015 in India 46
45. Determinants of Demand
Price of the product
Single most important determinant
Negative effect on demand
Higher the price-lower the demand
Income of the consumer
Normal goods: demand increases with increase in consumer’s income
Inferior goods: demand falls as income rises
Price of related goods
Substitutes
If the price of a commodity increases, demand for its
substitute rises.
Complements
If the price of a commodity increases, quantity demanded of its
complement falls.
47
46. 46
Determinants of Demand….
Tastes and preferences
Very significant in case of consumer goods
Expectation of future price changes
Gives rise to tendency of hoarding of durable goods
Population
Size, composition and distribution of population will
influence demand
Advertising
Very important in case of competitive markets
Growth of Economy
If economy is growing, demand for goods of better
quality will be high.
Consumer credit
Easy access to loans for purchasing consumer goods
47. 47
Demand Function
Interdependence between demand for a product and its
determinants can be shown in a mathematical functional
form
Dx = f(Px, Y,Py, T,A, Ef, N)
Independent variables: Px, Y,Py, T,A, N
Dependent variable: Dx
Px: Price of x
Y: Income of consumer
Py: Price of other commodity
T: Taste and preference of consumer
A: Advertisement
Ef: Future expectations
N: Macro variable like inflation, population growth,
economic growth
48. Law of Demand
A special case of demand function which shows relation between
price and demand of the commodity
Dx = f(Px)
Other things remaining constant, when the price of a commodity
rises, the demand for that commodity falls or when the price of a
commodity falls, the demand for that commodity rises.
Price bears a negative relationship with demand
Reasons
Substitution Effect : When the price of a commodity falls (rises),
its substitutes become more (less) expensive assuming their
price has not changed.
Income Effect: When the price of a particular commodity falls,
the consumer’s real income rises, hence the purchasing power of
the individual rises.
Law of Diminishing Marginal Utility: as a person consumes
successive units of a commodity, the utility derived from every
next unit (marginal unit) falls.

Market Demand
Market: interaction between sellers and buyers of a good
(or service) at a mutually agreed upon price.
Market demand
Aggregate of individual demands for a commodity at a
particular price per unit of time.
Sum total of the quantities of a commodity that all buyers in
the market are willing to buy at a given price and at a
particular point of time (ceteris paribus)
Market demand curve: horizontal summation of individual
demand curves
55. 55
Supply
• Indicates the quantities of a good or service that the seller
is willing and able to provide at a price, at a given point
of time, other things remaining the same.
• Supply of a product X (Sx) depends upon:
– Price of the product (Px)
– Cost of production (C)
– State of technology (T)
– Government policy regarding taxes and subsidies (G)
– Other factors like number of firms (N)
• Hence the supply function is given as:
Sx = (Px, C, T, G, N)
56. Law of Supply
Law of Supply states that other things remaining the same, the
higher the price of a commodity the greater is the quantity supplied.
Price of the product is revenue to the supplier; therefore higher price
means greater revenue to the supplier and hence greater is the
incentive to supply.
Supply bears a positive relation to the price of the commodity.

61. Market Equilibrium
Equilibrium occurs at the price where the quantity demanded and
the quantity supplied are equal to each other.
For prices below the equilibrium, quantity demanded exceeds
quantity supplied (D>S). Pulling price upward.
For prices above the equilibrium, quantity demanded is less than
quantity supplied (D<S). Pushing price downward.

62. Changes in Market Equilibrium
(Shifts in Supply Curve)
The original point of equilibrium is
at E, the point of intersection of
curves D1 and S1, at price P and
quantity Q
An increase in supply shifts the
supply curve to S2.
Price falls to P2 and quantityrises
to Q , taking the new equilibrium
2
to E2 .
A decrease in supply shifts the
supply curve to S0. Price rises to P0
and quantity falls to Q0 taking the
new equilibrium to E0
Thus an increase in supply raises
quantity but lowers price, while a
decrease in supply lowers quantity
but raises price; demand being
unchanged.

Whether price will rise, or
remain at the same level, or will
fall, will depend on:
the magnitude of shift and
the shapes of the demand
and supply curves.
Therefore, an increase in both
supply and demand will cause
the sales to rise, but the effect on
price can be:

CIRCULAR FLOW OF ECONOMIC ACTIVITIES AND INCOME
The simple model of the circular flow assumes two players:
Firms (Producer)
• Produce and supply the goods and services by considering the
various factors of production
Households (Consumer)
• Who is an individual who purchase goods and services
Households Provide services in terms of factor inputs to the firms
and get paid for these services by firms which households spend on
consumption.
Thus Money and economic activities flowing between firms and
households create a circular flow
It is a circular flow of money or income

Circular Flow of Economic Activities
and Income
• Value of output produced (Y) = value of output sold (O)
• Value of output sold = Sum of consumption expenditure (C) and
investment expenditure (I).
E = O = C+I
• Income is either consumed or saved (S).
Y = C+S = C+I
• Savings are withdrawal of money from the circular flow
• Investment is injection of money into the circular flow
• For equilibrium savings should be equal to investments
• Hence Y=O=E
79. 79
Circular Flow of Income
(Four Sector Economy)
The third sector is Government (G)
• Government Spending
– On provision of public utility goods and services.
– Provides salaries to the households
– Pays to firms for purchases of goods and services - public ltdcompanies
• Government Revenue
– Households and firms pay various taxes and other payments and provide
factor inputs to the government.
– Government borrows from the financial market to fill revenuegap.
The fourth sector is the external sector
• Imports (M): Outflow of income occurs when the domestic firms
buy goods and services from foreign ones.
• Exports (X): Inflow of income takes place when foreign firms buy
goods and services from domestic ones

Circular Flow of Income
(Four Sector Economy)
• National income includes expenditures on
investment, government and net of exports (X-M)
National Income=C+I+G+(X-M)
consumption,
• Since national income can either be consumed, or saved, or paid
as tax to the government:
C+I+G+(X-M)=C+S+T
• Sum of private investment and expenditure on net exports is equal
to the sum of savings and tax revenue. Thus:
I+G+X = S+T+M
• Therefore, W=J
• At equilibrium, total injections are equal to total withdrawals.
82. Macro-economic Variables
• Aggregate Demand and Aggregate Supply
–Aggregate Demand is the sum of demand for all goods and
services by all the consumers for a given period of time.
• aggregate demand (AD) for consumer goods i.e.
consumption demand (C)
• aggregate demand for capital goods i.e. (I).
Thus AD = C+I
• Aggregate supply is the total national output produced and
supplied by all the factors of production in an economy.
• It refers to the supply of all goods and services in the economy
for a given period of time.
• Aggregate supply (AS) consists of
–supply of consumer goods (C) and
–Supply capital goods (where capital comes from savings (S),
HenceAS=C+S 73
83. Macro-economic Variables….
• Stock and Flow
– Stock may be defined as any economic variable which has been
accumulated at a specific point of time
• like money, assets and wealth.
– Flow includes the variables which increase (inflows) and
decrease (outflows) the stock, over a period of time.
• like income, consumption, saving and investment
Stock=Inflows-Outflows
• Intermediate and Final Goods
– Intermediate goods (and services) are items purchased by firms
for using them in production of some other goods or utility.
(Partly finished goods or raw materials)
– Also known as producer goods because they are used as inputs
in the production of other goods.
– Final goods are those which are demanded by the final
consumer for using these goods as they are. 74
84. Macro-economic Variables….
• Capital formation
– The process of savings being converted into investment is known as
capital formation
– Gross Capital Formation refers to the aggregate of additions to fixed
assets (Fixed Capital Formation) and increase in stocks of inventories
during a period of time.
• Employment
– An employed person is willing and capable to work in a productive
activity and is engaged for certain number of hours per week, whether
working for self or someone else.
– The population of any country is divided into working population (age
group of 16 to 65 ) and dependents.
• Government Expenditure and Revenue
– Government Expenditure is which is made from public exchequer.
– Government Revenue is income received by government in various
forms, e.g. Taxes 75
