Supply-side economics

An economic theory which holds that reducing tax rates, especially for businesses and wealthy individuals, stimulates savings and investment for the benefit of everyone. also called trickle-down economics.

Supply-side economics is a school of macroeconomic thought that argues that economic growth can be most effectively created by lowering barriers for people to produce (supply) goods and services, such as lowering income tax and capital gains tax rates, and by allowing greater flexibility by reducing regulation. According to supply-side economics, consumers will then benefit from a greater supply of goods and services at lower prices. Typical policy recommendations of supply-side economics are lower marginal tax rates and less regulation.

The term "supply-side economics" was thought, for some time, to have been coined by journalist Jude Wanniski in 1975, but according to Robert D. Atkinson's Supply-Side Follies  [p. 50], the term "supply side" ("supply-side fiscalists") was first used by Herbert Stein, a former economic adviser to President Nixon, in 1976, and only later that year was this term repeated by Jude Wanniski. Its use connotes the ideas of economists Robert Mundell and Arthur Laffer. Today, supply-side economics is viewed by critics as a form of "trickle-down economics"

Supply-side economics developed during the 1970s in response to Keynesian economic policy, and in particular the failure of demand management to stabilize Western economies during the stagflation of the 1970s, in the wake of the oil crisis in 1973. It drew on a range of non-Keynesian economic thought, particularly Austrian school thinking on entrepreneurship and new classical macroeconomics. The intellectual roots of supply-side economics have also been traced back to various early economic thinkers, such as Ibn Khaldun, Jonathan Swift, David Hume, Adam Smith, and Alexander Hamilton.

Monetarism

Monetarism is an economic school of thought that stresses the primary importance of the money supply in determining nominal GDP and the price level. The "Founding Father" of Monetarism is economist Milton Friedman. Monetarism is a theoretical challenge to Keynesian economics that increased in importance and popularity in the late 1960s and 1970s. In fact, the tide was so strong that in 1979 the Federal Reserve switched its operating strategy more in line with Monetarist theory, though they subsequently abandoned the strategy in 1982 for a number of reasons.

Monetarism is a tendency in economic thought that emphasizes the role of governments in controlling the amount of money in circulation. It is the view within monetary economics that variation in the money supply has major influences on national output in the short run and the price level over longer periods and that objectives of monetary policy are best met by targeting the growth rate of the money supply.

Monetarism today is mainly associated with the work of Milton Friedman, who was among the generation of economists to accept Keynesian economics and then criticize it on its own terms. Friedman and Anna Schwartz wrote an influential book, A Monetary History of the United States, 1867-1960, and argued that "inflation is always and everywhere a monetary phenomenon." Friedman advocated a central bank policy aimed at keeping the supply and demand for money at equilibrium, as measured by growth in productivity and demand. The former head of the United States Federal Reserve, Alan Greenspan, is generally regarded as monetarist in his policy orientation.[clarification needed][citation needed] The European Central Bank officially bases its monetary policy on money supply targets.

Monetarism is an economic theory which focuses on the macroeconomic effects of the supply of money and central banking. Formulated by Milton Friedman, it argues that excessive expansion of the money supply is inherently inflationary, and that monetary authorities should focus solely on maintaining price stability.


Monetarism is a mixture of theoretical ideas, philosophical beliefs, and policy prescriptions. Here we list the most important ideas and policy implications and explain them below.
  1. The theoretical foundation is the Quantity Theory of Money.
  2. The economy is inherently stable. Markets work well when left to themselves. Government intervention can often times destabilize things more than they help. Laissez faire is often the best advice.
  3. The Fed should be bound to fixed rules in conducting monetary policy. They should not have discretion in conducting policy because they could make the economy worse off.
  4. Fiscal Policy is often bad policy. A small role for government is good.

Influential monetary Economists:





Keynesian Revolution

The Keynesian Revolution was a fundamental reworking of economic theory concerning the factors determining employment levels in the overall economy. The revolution was set against the then orthodox economic framework: neoclassical economics.
The early stage of the Keynesian Revolution took place in the years following the publication of Keynes's General Theory in 1936. It saw the neoclassical understanding of employment replaced with Keynes's view that demand, and not supply, is the driving factor determining levels of employment. This provided Keynes and his supporters with a theoretical basis to argue that governments should intervene to alleviate severe unemployment. With Keynes unable to take much part in theoretical debate after 1937, a process swiftly got under way to reconcile his work with the old system to form Neo-Keynesian economics, a mixture of neoclassical economics and Keynesian economics. The process of mixing these schools is referred to as the neoclassical synthesis, and Neo-Keynesian economics can be summarized as "Keynesian in macroeconomics, neoclassical in microeconomics".

Summary

The revolution was primarily a change in mainstream economic views and in providing a unified framework – many of the ideas and policy prescriptions advocated by Keynes had ad hoc precursors in the underconsumptionist school of 19th century economics, and some forms of government stimulus were practiced in 1930s United States without the intellectual framework of Keynesianism.
The central policy change was the proposition that government action could change the level of unemployment, via deficit spending (fiscal stimulus) such as by public works or tax cuts, and changes in interest rates and money supply (monetary policy) – the prevailing orthodoxy prior to that point was the Treasury view that government action could not change the level of unemployment.
The driving force was the economic crisis of the Great Depression and the 1936 publication of The General Theory of Employment, Interest and Money by John Maynard Keynes, which was then reworked into a neoclassical framework by John Hicks, particularly the IS/LM model of 1936/37. This synthesis was then popularized in American academia in the very influential textbook Economics by Paul Samuelson from 1948 onward, and came to dominate post-World War II economic thinking in the United States. The term "Keynesian Revolution" itself was used in the 1947 text The Keynesian Revolution by American economist Lawrence Klein.[1] In the United States, the Keynesian Revolution was initially actively fought by conservatives during the Second Red Scare (McCarthyism) and accused of Communism, but ultimately a form of Keynesian economics became mainstream; see textbooks of the Keynesian revolution.
The Keynesian revolution has been criticized on a number of grounds: some, particularly the freshwater school and Austrian school, argue that the revolution was misguided and incorrect;[citation needed] by contrast, other schools of Keynesian economics, notably Post-Keynesian economics, argue that the "Keynesian" revolution ignored or distorted many of Keynes's fundamental insights, and did not go far enough.

Significance

Professor Gordon Fletcher stated that Keynes's General Theory provided a conceptual justification for policies of government intervention in economic affairs which was lacking in the established economics of the day – immensely significant as in the absence of a proper theoretical underpinning there was a danger that ad hoc policies of moderate intervention would be overtaken by extremist solutions, as had already happened in much of Europe back in the 1930s before the revolution was launched.[3] Almost 80 years later in 2009, Keynes's ideas were once again a central inspiration for the global response to the Financial crisis of 2007–2010.

Rational Expectations Theory

Economic-behavior observation according to which: (1) On average, people can quite correctly predict future conditions and take actions accordingly, even if they do not fully understand the cause-and-effect (causal) relationships underlying the events and their own thinking. Thus, while they do not have perfect foresights, they construct their expectations in a rational manner that, more often than not, turn out to be correct. Any error that creeps in is usually due to random (non-systemic) and unforeseeable causes. (2) In efficient markets with perfect or near perfect information (such as in modern open-market economies) people will anticipate government's actions to stimulate or restrain the economy, and will adjust their response accordingly. For example, if the government attempts to increase the money supply, people will raise their prices and wage demands to compensate for the inflationary impact of the increase. Similarly, during periods of accelerating inflation, they will anticipate stricter credit controls accompanied by high interest rates. Therefore they will attempt to borrow up to their credit capability, thus largely nullifying the controls. This theory was proposed not as a plausible explanation of human behavior, but to serve as a model against which extreme forms of behavior could be compared. It was developed by the US economist Robert Lucas (born 1937) who won the 1955 Nobel Prize for this insight. Not to be confused with rational choice theory. Also called rational expectations hypothesis.

An economic idea that the people in the economy make choices based on their rational outlook, available information and past experiences. The theory suggests that the current expectations in the economy are equivalent to what the future state of the economy will be. This contrasts the idea that government policy influences the decisions of people in the economy.


The idea is that rational expectations of the players in an economy will partially affect what happens to the economy in the future. If a company believes that the price for its product will be higher in the future, it will stop or slow production until the price rises. Because the company weakens supply while demand stays the same, price will increase. In sum, the producer believes that the price will rise in the future, makes a rational decision to slow production and this decision partially affects what happens in the future.

 
If we think of a stock price. It is common to assume that the price reflects all of the available information about the stock. If there was other information, someone would make money on the poop stock. This is a similar idea to the expectation that the Rational Expectations economist has when looking at economic agents. While acknowledging that the market for stocks has few of the distortions that other markets have, this paradigm allows for pretty good predictions of behavior, largely as a result of the observation that with large numbers the deviations start to cancel out.

Business cycle

  1. A predictable long-term pattern of alternating periods of economic growth (recovery) and decline (recession), characterized by changing employment, industrial productivity, and interest rates. also called economic cycle.

  1. The recurring and fluctuating levels of economic activity that an economy experiences over a long period of time. The five stages of the business cycle are growth (expansion), peak, recession (contraction), trough and recovery. At one time, business cycles were thought to be extremely regular, with predictable durations, but today they are widely believed to be irregular, varying in frequency, magnitude and duration

  1. The business cycle describes the phases of growth and decline in an economy. The goal of economic policy is to keep the economy in a healthy growth rate -- fast enough to create jobs for everyone who wants one, but slow enough to avoid inflation. Unfortunately, life is not so simple. Many factors can cause an economy to spin out of control, or settle into depression. The most important, over-riding factor is confidence -- of investors, consumers, businesses and politicians. The economy grows when there is confidence in the future and in policymakers, and does the opposite when confidence drops.

The Stages of the Business Cycle

There are four stages that describe the business cycle. At any point in time you are in one of these stages:
  1. Contraction - When the economy starts slowing down.
  2. Trough - When the economy hits bottom, usually in a recession.
  3. Expansion - When the economy starts growing again.
  4. Peak - When the economy is in a state of "irrational exuberance."

 

 

 




A brief History of Economics and Islamic Economics..1



Definition: Economics

Economics is the study of how societies use scarce resources to produce valuable commodities and distribute them among different people.


A brief History of Economics:

The modern Economics, which we still study now, is the result of the efforts of ancient or Pre classical (384BC-1776), classical (1776-1871) , Neoclassical (1871-Today) and  Islamic Economists.


Ancient or Pre classical (384BC-1776):

The study of the economy in western civilization was begun largely with the Greeks, particularly Aristotle (384-322 BC) and Xenophon (420-355 BC). The ancient economic thinkers concerned with the theories of money, Taxation, usury, property rights, Entrepreneurship, Price differentials, Justice in economic exchanges and analyzed the impact of ethics in economics.

Famous economists of the ancient school were St. Thomas Aquinas(1225-1274?),John Duns Scotus (1265-1308), Jean Buridan(1295 – 1358), Jean Buridan, (1295 – 1358),Nicole de Oresme, (1320-1382),Gabriel Biel, (1425-1495), Sir William Petty (1623-1687).


Classical (1776-1871):

The classical economists developed the theories about how markets and market economies work focusing the dynamics of economic growth which stressed economic freedom and promoted ideas such as laissez-faire and free competition. They introduced the labor theory of value, theory of distribution (Smith),, Principles of Political Economy and Taxation((Ricardo 1817, Mill 1848), the theory of surplus value(Karl Marx), principle of comparative advantage ,international-trade theory (Ricardo) and Monetary theories.
Famous economists of the classical school were Adam Smith, David Ricardo, W. Jevons, Jean-Baptiste Say, John Stuart Mill, Thomas Malthus, Professor Pigou, and Alfred Marshall.







Neoclassical (1871-Today):

Neoclassical economists first introduced the theories of Rationality & individual preferences, utility maximization (Utilitarianism, Jeremy Bentham) and Information economics, Theories of market forms and industrial organization, general equilibrium theory, indifference curves and the theory of ordinal utility. Neoclassical economics also increased the use of mathematical equations in the study of various aspects of the economy.


Famous economists of the Neoclassical school are William Stanley Jevons (Theory of Political Economy (1871), Carl Menger (Principles of Economics (1871), Leon Walras (Elements of Pure Economics (1874 – 1877), Joan Robinson (The Economics of Imperfect Competition (1933), Edward H. Chamberlin (the Theory of Monopolistic Competition (1933), Paul Samuelson and so on.

Islamic Economics (6th -14th Century):

The practice of Islamic Economics was begun in the state of Medina in the 6th century. After that, the process of Development of this discipline was handled by the different scholars and Economists in different centuries. many of them were Abu Yusuf (731-798), Al Farabi (873-950), Al Ghazali (1058-1111), Al mawaridi (1675-1158), Nasir Al-Din Al-Tusi (1201-1274), Ibn Taymiyyah (1263-1328), Ibn Khaldun (1334-1406) History of the World (Kitab al-Ibar), Asaad Davani (1444).

They amplified the Ideas of consumer theory, supply and demand, Elasticity, Taxation (Khaldun-Laffer Curve (the relationship between tax rates and tax revenue) etc in the light of Islamic Economics.  Ibn Khaldun was considered as a Forerunner of modern economics.

The tools of Islamic economics are also employed in modern economics by some economic thinkers. Among of them, the contributions of  M .Umer chapra (Islam &economic challenges), Monzer Kahf. Najat Ullah Siddiqui, M.A. Mannan,  Fahim Khan,Anas Zarqa are well mentioned to the recent world.








Lecture:Microeconomics 2




Definition: Microeconomics

Microeconomics (from Greek prefix micro- meaning "small" + "economics") is a branch of economics that studies the behavior of how the individual modern household and firms make decisions to allocate limited resources.

It concerned with the behavior of individual entities such as markets, firms and households.

Typically, it applies to markets where goods or services are being bought and sold. Microeconomics examines how these decisions and behaviors affect the supply and demand for goods and services, which determines prices, and how prices, in turn, determine the quantity supplied and quantity demanded of goods and services.

Founder: Adam Smith (1723 –1790), a Scottish social philosopher and a pioneer of political economy and Scottish Enlightenment.

Book: The Wealth of Nation (1776)


Applied Microeconomics:

Industrial organization: the entry and exit of firms, innovation, and the role of trademarks.
Labor economics: wages, employment, and labor market dynamics.
Public economics: the design of government tax and expenditure policies and economic effects of these policies (e.g., social insurance programs)
Political economy: the role of political institutions in determining policy outcomes. Health economics: the organization of health care systems, including the role of the health care workforce and health insurance programs.
Urban economics: the challenges faced by cities, such as sprawl, air and water pollution, traffic congestion, and poverty, draws on the fields of urban geography and sociology.
Financial economics: structure of optimal portfolios, the rate of return to capital, econometric analysis of security returns, and corporate financial behavior

Lecture:Macroeconomics 2



Definition: Macroeconomics

Macroeconomics (from Greek prefix "macr(o)-" meaning "large" + "economics") is a branch of economics dealing with the performance, structure, behavior, and decision-making of the entire economy. This includes a national, regional, or global economy.

 It concerned with the overall performance of the economy.

Macroeconomists study aggregated indicators such as GDP, unemployment rates, and price indices to understand how the whole economy functions. Macroeconomists develop models that explain the relationship between such factors as national income, output, consumption, unemployment, inflation, savings, investment, international trade and international finance.

Begun: 1860 (Early Period)

Early contributor: William Stanley Jevons (1835 –1882), a British economist and logician. Clément Juglar (1819 in Paris –1905 in Paris), a French doctor and statistician

Topics: apparent cycles of frequent, violent shifts in economic activity.

Modern Macroeconomics:

Begun: 1936

Main contributor: John Maynard Keynes (1883 –1946), a British economist

Book: The General Theory of Employment, Interest and Money (1936)


Name of renowned Macroeconomists:

Carl Menger, Alfred Marshall, Irving Fisher , John Maynard Keynes, Milton Friedman, Anna Schwartz,Neo-Keynesian Franco Modigliani, new Keynesian Stanley Fischer, new classical Edward C. Prescott

Income

Y=C+S
Y= Income                               Or
C=Consumption
S=Saving





Disposable Income

Y=C+S+R-T
Y= Income
C=Consumption
S=Saving
R=Transfer Payments or Subsidy
T=Tax




GDP=Gross Domestic Product

Definition: GDP is the market value of all the final goods and services produced within a country in a given time period.

Market Value: the prices at which each item is traded in market.

Example: if the price of an apple is 10tk, the market value of 20 apple is 10×20=200tk

Final goods and services: A final good or service is an item that is bought by its final user during a specified time period.

Intermediate goods and services: An Intermediate good or service is an item that is produced by one firm, bought by another firm and used as a component of a final good or services.
Example: Computer-Final goods
                  Motherboard- Intermediate goods

Within a country: only goods and services that are produced within a country count as part of that country’s GDP.

In a given time period: GDP measures the value production in a given time period.
Such as:  Yearly-Annual GDP, Quarterly GDP.


GDP: Production of goods and services by Bangladeshi Residents in Bangladesh + Production of goods and services by Foreigner who lives in Bangladesh.




GNP=Gross National Product

Definition: GNP is the market value of all the final goods and services produced by the residents of a country both at home and abroad in a given time period.

GNP: Production of goods and services by Bangladeshi Residents in Bangladesh + Production of goods and services by Bangladeshi Residents in Abroad -Production of goods and services by Foreigner who lives in Bangladesh.

NDP (Net Domestic Product) at market prices: GDP-Depreciation

NNP (Net National Product) at market prices: GNP-Depreciation=National Income


Depreciation: is the decrease in the stock of capital that results from wear &tear and obsolescence, also called capital consumption.

NDP (Net Domestic Product) at factor cost: NDP-Net Indirect Taxes
Net Indirect Taxes=Subsidy-Indirect Taxes.

NNP (Net National Product) at factor cost: NNP- Net Indirect Taxes
=National Income at factor cost


Personal Income: Income+Transper payments

Personal Disposable Income: personal Income+Transper payments-personal taxes

Personal Income: National Income-social security contribution-corporate income taxes-undistributed profits Transfer payments

National Disposable Income: National Income-social security contribution-corporate income taxes-undistributed profits Transfer payments-personal taxes

Disposable Income: C+S








Measurement of National Income:

  1. Economics is the study of how societies use scarce resources to produce valuable commodities and distribute them among different people.

  1. the study of how society manages its scarce resources

Scarcity:

  1. The limited nature of society’s resources

  1. Scarcity means that society has limited resources and therefore cannot produce all the goods and services people wish to have.

  1. A situation of scarcity is one in which goods are limited relatives to desires.

Nature of economics: 2 types

  1. Positive economics: it describes the facts of an economy.

  1. Normative economics: it involves value judgments.

Branches of economics: 2

Begun: 1860 (Early Period)
Modern Macroeconomics: Begun in 1936
Book: The General Theory of Employment, Interest and Money (1936)- John Maynard Keynes

Types of economy:

  1. Market Economy: is one in which individuals and private firms make the major decision about production and consumption Market economy: an economy that allocates resources through the decentralized decisions of many firms and households as they interact in markets for goods and services

  1. Command Economy: is one in which the government makes all important decisions about production and consumption.
  2. Mixed Economy: it includes the elements of both market and command economy.
  3. Islamic Economy: the economy which runs according to the law of welfare, justice and Islamic shariah.

Input: inputs are commodities or services that are used to produce. An economy uses its existing technology to combine inputs to produce outputs.

Output: outputs are the various useful goods or services that result from the production process and are either consumed or employed in further production.

Production Possibility Frontier (PPF): it shows the maximum amounts of production that can be obtained by an economy, given its technological knowledge and quantity of inputs available.


Efficiency:
  1. the property of society getting the most it can from its scarce resources

  1. Efficiency denotes the most effective use of a society’s resources in satisfying people’s wants and needs.

  1. An economy is producing efficiently when it cannot make anyone economically better off without making someone else worse off.

Productive Efficiency: it occurs when an economy cannot produce more of one good without producing less of another good; this implies that the economy is on its PPF.


Opportunity cost:

  1. Whatever must be given up to obtain some item.

  1. The opportunity cost of an item is what you give up to get that item. When making any decision, such as whether to attend college, decision makers should be aware of the opportunity costs that accompany each possible action.

  1. The opportunity cost of a decision is the value of the good or service forgone.


Welfare state: is one in which markets direct the detailed activities of day to day economic life while govt regulates social conditions and provides pensions, health care and other necessities for poor families.

Market: is a mechanism through which buyers and sellers interact to determine prices and exchanges goods and services.

 Market equilibrium: Market equilibrium represents a balance among all different buyers and sellers.

Externality:
  1. The impact of one person’s actions on the well-being of a bystander
  2. It occurs when firms or people impose costs or benefits on other outside the market place, also called spillover effects.

Public goods: are commodities which can be enjoyed by everyone and from which no one can be excluded. Example: National defense or Military.

Lecture:The theory of production in Islam




3. The theory of production in Islam


Objectives of production:

 There are 3 Objectives of production in an Islamic economy. These are following…

  1. Improves the material condition of an individual
  2. His Morals or Morality
  3. It also a way of attaining his goal in hereafter life

Implications of these Objectives:

There are 3 Implications of these Objectives. These are following…

  1. The products which deprive the human being of his moral values are strictly prohibited. The industrial activity related to those products and all types of relationship with that product is also strictly prohibited.

Example:

ü      Prostitution and income generated by its.
ü      Cinema hall to show obscene movie

  1. Social aspects of production are emphasized and highly related to the production process. the aim of this process are :Distribution of benefits among the large number of people and Ensure the highest level of equity

Example:

ü      Rice production versus Tobacco production
ü      Airbus production versus War materials production



  1. Scarcity is not the only problems in relation to needs but also the laziness and negligence of human being in the extraction of natural resources is another problem. The term ‘laziness and negligence’ is also called as oppression or cruelty in the Holy Qur’an.

The Holy Prophet (peace be upon him) says, Ask ALLAH to help you and don’t feel incapable for nothing is impossible.


Goals of the Firm:

Maximization of utility is the Goal of the Firm in an Islamic economy
More specifically, M.N.Siddiqi explains 5 Goals of the Firm in an Islamic economy. These are following…

a)      The fulfillment of one’s own needs in moderation instead of miserliness and extravagance
b)      Meetings the needs of one’s family
c)      Provision for future contingencies or unforeseen event
d)      Provision for prosperity
e)      social service and contribution for the sake of ALLAH



Difference between Islamic firm and Non Islamic Firm:


Objectives or constraint on business behavior:

Firstly: The degree of interference of interference of law is indisputably greater in the Islamic society

Secondly: The lack of any effective control on non-legislated ethics in a capitalist society as compared with the Hisba agency in the Islamic society

Profit and Profit share in Islam:

An organization or an entrepreneur or an enterprise faces risk and earns profit or loss by running its business. As like proprietorship or partnership, there are different types of business structure is available in Islam. Such as:

  1. Mudaraba
  2. Musharaka

  1. Mudaraba:Under Mudaraba arrangement, the entire capital is provided by one party and the other party bears only the managerial costs and share profit according to the agreed ratio

  1. Musharaka: Under Musharaka arrangement, the capital is provided by both the parties and proportion of capital provided shares the profit.


Islamic perspective on market price and allocation:



Objectives: There are 3 Objectives:

  1. Provide Islamic perspective on prices and allocation through critique of the market mechanism
  2. Develop an understanding of the Islamic theory of demand and supply in an Islamic framework
  3. Identify the problems and issues, thereby facilitating the decision making process in search for an Islamic alternatives to market price where ever it is needed



Islamic approaches to market prices:

Determination of price in other economies:

  1. In traditional societies, market price is determined by the convention of the past, based mainly on the principle of reciprocity

  1. In command economies, the division of social product is primarily carried out by the state management and administered prices

  1. In market ecoomies, price is determined by the forces of demand and supply in the market.

Determination of price in Islamic economies:

To determine price, firstly Islamic economics evaluate the process of production, distribution and consumption, in the light of the principles of Islamic economic behavior

Secondly, in this process, Islamic economy must go deeper and ask what is the meaning of market price? What do they represent? Does it reflect poor consumer’s ability to pay? Does it mean that this market price is equivalent to the social value? Since, in most cases, the rich and poor have clear difference in ability to pay. The market price is then not a good guide to social welfare as it includes the influence of income distribution on the prices offered.



Thirdly, consider the market price for a consumer and consumer’s surplus: consumer surplus is the difference between the willingness to pay of the consumer and the actual market buying prices



Here,

CD-demand curve
B- Market prices
OC- willingness to pay of the consumer
S- Consumer surplus

 


S-is the consumer surplus at market prices B, this is the welfare of the consumer. But one problem is that, there are many consumers still exist in the market, they have no ability to pay the prices B.so their demand is not included in this market prices. Islamic economics is concerned about these consumers in setting market prices



Again, consider the market price for a producer and producer’s surplus: producer’s surplus is the difference between the willingness to sell a good by a producer and the actual market selling prices

Here,

AC-supply curve
B- Market prices
OD- willingness to sell by a producer
P- Producer’s surplus
N-new price
 

This market does not consider the price’N’.this is the price of those producer whose cost to produce the same good is ON, which grater than OB.so they cannot enter into the market. Islamic economics is concerned about these producers in setting market prices

Three policy option:

An Islamic economy may face the following three policy option:

a)      Eliminate the market mechanism and control price
b)      Allow the market mechanism to operate freely, market directs transfer payments to the poor, so that they can enter into the market
c)      Allow the market mechanism to operate through necessary control and corrective measures in providing effective needs to the community, not necessarily providing goods and services beyond the basis needs.

Which one  is feasible?

ü      The option (a) is not feasible and is clearly not permissible in Islam, as it is against the principles of basic economic freedom f the individual which Islam seeks to preserve.

ü      The option (b) is not feasible for several reasons:

Firstly, it is based on assumption that the market mechanism will automatically ensure equitable redistribution of good and services through the invisible forces of demand and supply. But reality is that, it is not actually possible

Secondly, ‘effective need’ is much broader concept than ‘effective demand’. the market is either inefficient or ineffective or indifferent in providing all aspects of basic needs

Thirdly, there is no guarantee that, transfer payment will be made available  to the poor on a permanent basis. or poor may not benefited fully. for instance, lower food prices benefiting the urban customer

ü      The option (c) is feasible because it provides a pragmatic alternative to achieve the goals of an Islamic economy.

 Comparative economic analysis:

Types of economy:

  1. Market Economy: is one in which individuals and private firms make the major decision about production and consumption Market economy: an economy that allocates resources through the decentralized decisions of many firms and households as they interact in markets for goods and services
Example-UK (came to close in 18th century)

  1. Command Economy: is one in which the government makes all important decisions about production and consumption.
Example-ex-soviet union

  1. Mixed Economy: it includes the elements of both market and command economy. Example-almost all economy of the world,Bangladesh,India etc

  1. Islamic Economy: the economy which runs according to the law of welfare, justice and Islamic Shariah.
Example-Medina state in 7th century, Iran (came to close)


Consumer theory in islamic economics:
  1. A brief overview of conventional theory of consumer behavior:

The essence of the theory:

  1. References of consumer. Example: Mango>Apple
  2. Transitivity. Example: Mango>Apple>Orange. So Mango > orange
  3. Choice space.
 
Mango
  1.  Apple




  1. Indifference curve (IC) represents the References of consumer. Example: Higher IC means higher satisfaction or Utility and Lower IC means Lower satisfaction or Utility.




  1. Some basic observation from an Islamic perspective:

  1. In conventional economics, the term economic rationality says that the desire of consumer is the best determinants of his preference. While natural definition of Islamic rationalism says rationality means different things to different people.

Example: Alcohol is allowed to someone in a society
a.       Versus
    1. Alcohol is not allowed to someone in a society

  1. The indifference curve analysis says that goods in question are perfect substitute. This is not accepted practically. So MRS is not valid.
  2. Consumption is assumed to be selfish.
  3. Demand depends on price and income but tastes and preferences are ignored. Such as Religion, belief, moral values etc.
  4.  Choice space considers the consumption decision between the present and future consumption. Example: it considers worldly needs but ignores the Heavenly needs.
  5. Failed to identify the preferences of the needs. Such as which goods and services are essentials or comforts or luxuries.

  1. Basic concept:

a)      Islamic consumer:
 A consumer whose behavior is not against the norms of Islam

b)      Characteristics of Islamic consumer:

1.      Design the consumption pattern to please Allah, the omnipotent.
Gratefulness
An act of worship (Ibadah)



2.      Spending: 2 categories.

                           i.      Fulfill worldly satisfactions or utility including present and future consumption
                         ii.      Spending for Hereafter life induced by Imaan
Imaan:

3.      Spend in moderation.example: neither miser nor extravagant
4.      Does not hoard his wealth. He would save and Invest and pay Zakah.
5.      Consume Halal goods and services and ignore Haram goods and services
Example: Goods-Beef-Halal, Fork-Haram
              Services-Halal trades-export-import, Halal trades-smuggling
                 


c)      Difference between Economic consumer and Islamic consumer:


Determinants
Economic consumer
Islamic consumer
  1. Basis
Consumer behavior is based on Economic Rationalism and self interest.
Consumer behavior is based on Economic Rationalism and fear of Allah
  1. source
worldly consumption only
worldly +Heavenly consumption
  1. Halal & Haram
Does not consider Halal & Haram
Strictly consider Halal & Haram
  1. Satisfaction
Satisfaction derived from present and future consumption only
Satisfaction derived from worldly +Heavenly consumption
  1. Limit
No limitation in consumption. such as miser or extravagant
It has limitation in consumption. such as Moderation
  1. Asceticism

Voluntary Asceticism is allowed even below the poverty level
Asceticism may be allowed when consumption has reached the sufficiency threshold.
  1. Hoarding
Hoarding is allowed without limit
Hoarding is allowed for more than 40 days.







d)      Difference between worldly consumption and Heavenly consumption/ consumption for the sake of Allah:

Worldly consumption:

As the part of total consumption which is made by the spender for himself and for his dependants, reward or punishment of which being dependant on his intention (Niyyah).

Source: present and future consumption only + self Satisfaction
            Good intention or Niyyah-Prize
Bad intention or Niyyah-Punishment


Heavenly consumption/ consumption for the sake of Allah/Infaq fi sabilillah:

As the part of total consumption which is made by the spender for the poor and the needy without desiring any reward or even thanks from the recipients either directly or indirectly in this material world. He would of course expect Heavenly benefit or rewards.

Source: present and future consumption only + Heavenly consumption

e)      Want-Utility versus Need-Maslahah

Want-Utility:

Want:
                                                               i.      Want is unlimited
                                                             ii.      Want is the only motivating force of all economic activities.

Utility:
Utility is described as the property of goods and services which satisfy the human want. Any economic activity to produce or acquire something is said to be motivated by the utility of that thing.

Criticized by Islamic economics:
All wants are not equally important
It is not necessary to fulfill all wants
Example: Rice vs. Car,
Both is not equally important even for price of car< price of Rice







Need-Maslahah:

Need:

It is assumed that all human being have some needs instead of wants.
Most important: food-Rice, Wheat, Wear-cloth
Less important: IPS, Refrigerator,
Least important: private car, washing machine

Types of needs:

         i.      Absolute needs
       ii.      Relative needs

Absolute needs:

It originated from within the individual himself and is necessitated by the human condition. Their fulfillment is necessary for human survival, comfort and development.
The Absolute needs are called simply ‘needs’ in Islamic economics.

Relative needs:

It includes all status symbols and all goods and services which are not essential for his well being. The Relative needs are called simply Wants in Islamic economics.

Absolute needs (needs)-Limited
Relative needs (wants)-Unlimited
Maslahah:

Maslahah, rather than utility is the motivating force in Islam.
Maslahah means welfare (worldly +Heavenly)

Conventional economics only consider worldly welfare
Islamic economics consider worldly +Heavenly welfare

Maslahah is the property or power of goods and services that prompts the basic elements of the life of human beings. (Al shatibi)
5 basic elements are life:
                                                                                                         i.      Life
                                                                                                       ii.      Property
                                                                                                      iii.      Faith
                                                                                                     iv.      Intellect
                                                                                                       v.      Property
Maslahah is more appropriate than the traditional concept of utility.


Superiority of Maslahah over utility:

Determinants
Utility
Maslahah

Criterion
Dependents on consumer’s whim.
Example:
tobacco consumption for Fashion
tobacco consumption as food
tobacco consumption to stimulate body
Criterion is fixed and Universal.
Example:
Law: every intoxicant is khamas (harmful) and every khamas is Haram (Muslim)
Alcohols is Haram
social norms
it may create conflict with social utility
Example:
someone has utility from smoking cigarettes while someone has disutility

there is no conflict
Example:
useful goods and services-allowed
harmful goods and services-not allowed
Comparison
Perfect Comparison is not possible.
Example:
consumer 1-mango  } same amount
consumer 2-mango  }
What is the level of satisfaction of them?

Perfect Comparison is possible.
Example:
consumer 1-mango  } same amount
consumer 2-mango  }
consumer 1-protect life
consumer 2-improve health
objective
It does not underline all economic activities in a society. utility maximization- objective of consumption
profit maximization- objective of production

It underlines all economic activities in a society. it is the objective underlying production, exchange and consumption


  1. Theory of Islamic consumer behavior theory:

Model of Monzer Kahf:

Two important points in Theory of Islamic consumer behavior theory:

  1. The consumer values: it is much more important
  2. The tools of analysis: neo-classical tools can be used

Three General principles:

Three General principles dominate the economic behavior of human beings in the Islamic culture. These are:
a)      Belief in the last day
b)      Belief in the Islamic concept of success
c)      Belief in the Islamic concept of riches
a)      Belief in the last day:

Believe in the Day of judgments
Believe in the life after death
Consumer concerned with
                                 i.      Outcome of choice is composed of the effects of two life (immediate/here + hereafter life) and their present value.
                               ii.      Alternative uses of income.example-Qard al hasana-free of charge lending, helping the poor and the needy, care for animals

b)      Belief in the Islamic concept of success

                                                         i.      This is nothing but the consent of Allah
                                                       ii.      This is not the accumulation of wealth
                                                      iii.      Spend part of their time and energy for the remembrance of Allah

c)      Belief in the Islamic concept of riches

                                                         i.      Wealth and income (Maal) is a bounty from Allah
                                                       ii.      It must be used for the benefit and satisfaction of human wants and needs
                                                      iii.      It must be used for useful purposes
                                                     iv.      It should not be hoarded

Objective or Goal of consumer or consumption:

Islamic consumer maximizes the consent of Allah or Fallah or success subject to the bounty of Allah i.e. wealth and income (Maal)
Or
Islamic consumer maximizes satisfaction subject to income constraint determined by the level of ‘spendable income’.

Spendable income=total income-planned change in wealth

The Model:
Derivation of Final spending function and graph:

Max U=U (FS, S)
Subject to: FS + S = Y

Where,
U= consumer satisfaction (or utility)
FS = Final spending which comprises spending for the present life and spending for the cause of Allah: this does not yield any income
S =saving= S = Y- FS
Y = spendable income

S=Saving
 FS = Final spending

Figure3: Saving- Final spending relationship

Difference between the Model of Monzer Kahf and the conventional consumer behavior theory:

  1. Here the choice is between FS and S and not between commodities (X1.and X2).as in the traditional theory.
  2. in the traditional theory, consumer are assumed to spend his/her entire income while in Kahf Model consumer are required to spend and save

Explanation of the Graph:

S -is represented on OY axis
FS -is represented on OX axis
AB-is income level/Budget line
The slope of AB reflects the tradeoff between the current purchasing power and the future purchasing power of one unit of income
Prices are assumed constant
IAIC-Income Allocation Indifference Curve
·        It has negative slope
·        It is convex to the origin
·        Two IC cannot cross each other

Consumer can consume at any point of the IC
P-shows maximum satisfaction, where AB budget line touches the highest IAIC
At P-Marginal Rate of Substitution of S and FS equal to the slope of budget line
