Economics is often called the "dismal science" or a "failed science," criticized for being hard to understand, especially for those without a background in it.
John Maynard Keynes is acknowledged as the father of macroeconomics, a branch that emerged with the publication of his influential work, "The General Theory of Employment, Interest, and Money," in 1936.
Microeconomics Vs Macroeconomics
An economy is like the action of economics in motion. Countries, companies, and families each have their own economies. We commonly refer to this in the context of nations, such as the Indian economy, the US economy, or the Japanese economy. Even though the principles and theories of economics are consistent, the economies of different countries vary due to their socio-economic differences.
Sectors of Indian Economy
Primary Sector: This involves activities that exploit natural resources, like mining, agriculture, and oil exploration. If agriculture contributes significantly to the national income, it's called an agrarian economy.
Secondary Sector: This sector processes raw materials from the primary sector, also known as the industrial sector. Manufacturing, a sub-sector, is a major employer in developed economies. When this sector contributes significantly to national income, it's referred to as an industrial economy.
Tertiary Sector: This includes activities where services are produced, such as education, healthcare, banking, and communication. If this sector contributes a large part to the national income, it's known as a service economy. There are two additional sectors—quaternary and quinary—considered sub-sectors of the tertiary sector.
Quaternary Sector: Known as the 'knowledge' sector, it involves activities related to education, research, and development, crucial for defining the quality of human resources in an economy.
Quinary Sector: This is where top-level decisions are made, involving high-level decision-makers in government and private corporations. It's considered the 'brain' behind socio-economic performance, with a small number of people involved.
Human life depends on using certain things, like goods and services, and some of these are essential for survival, such as food, water, shelter, and clothing.
The question is, who will invest, and why?
In addressing this challenge, different types of economic systems, or ways of organizing an economy, have evolved. While there are many economic systems, three major ones stand out. Let's take a brief look at them in the following sections.
Market Economy
Resulting Economic Systems - Capitalism and Free Market Economy:
How It Worked and Challenges:
Old System - Capitalism and Challenges:
Advantages and Disadvantages of Market Economy
In simple terms, The old system faced challenges, especially during the Great Depression. Economist Keynes suggested combining some ideas from a different system to fix things, leading to a mix that helped economies recover.
New Economic System - Socialism and Communism: Inspired by Karl Marx: This system, influenced by Karl Marx, had two types - socialist and communist. In socialism (like ex-USSR), the state-controlled natural resources. In communism (like China), the state also controlled labor.
Non Market Economy
Main Ideas:
How it Worked:
Downsides of Socialism and Communism:
Lack of Capital Creation: The systems lacked a focus on creating wealth or capital, resulting in a shortage of funds for future investments.
Resource Misallocation: State-controlled prioritization of resources led to misallocation and wastage, ignoring market-driven optimal resource uses.
Absence of Innovation: The absence of property rights and monetary rewards discouraged hard work, leading to a lack of innovation, research, and development.
Non-Democratic Systems: Lack of political freedom and liberties in non-democratic systems, with the state becoming the sole exploiter, termed as 'state capitalism.'
Internal Decay: From the 1970s, internal decay plagued these economies, with the state facing inherent challenges.
Transition to Market Economy: By the mid-1980s, both the ex-USSR and China shifted toward mixed economies, combining socialist and market traits. Reforms like Perestroika and Glasnost in the ex-USSR and China's Open Door Policy marked a move towards a more market-oriented approach.
Mixed Economy
Insights from the World Bank: The World Bank recognized the necessity of state intervention in the market economy, deviating from its strong support for the free market. It acknowledged that both market and non-market systems have shortcomings, suggesting an optimal economic system is a fusion of both.
Key Attributes of Mixed Economy:
Mixed Economic System
A mixed economy is flexible, capable of adjusting to socio-economic needs, marking a departure from rigid models of market and non-market systems. This resolves the longstanding debate about the role of the state in the economy.
There are three ways we handle getting stuff to people. Imagine it like this:
Types of Economic System
Capitalist Economy: Things are sold in a market. You buy what you need at a price set by the market.
State Economy: The government takes charge. They give things to people directly without anyone paying.
Mixed Economy: It's a mix of the first two. Some things you buy from the market, and for some, the government steps in. Sometimes, the government gives them for free or at a lower price.
People seem to like the mixed way, using both market and government. But over time, different ideas influenced it. Some of these ideas had a big impact on the world's economies.
The Washington Consensus is like a list of suggestions made by big organizations (IMF, World Bank, US Treasury) to help countries that are facing economic problems. These suggestions were given by experts in Washington, so that's why it's called the "Washington Consensus."
Here are the 10 things they suggested:
The Washington Consensus, initially a set of suggestions to help countries facing economic problems, later became linked to ideas like extreme free-market beliefs. Some people see it as a rigid commitment to the belief that markets can handle everything.
China has become economically strong since the mid-1980s, and people have debated whether it followed a specific plan for this. In 2004, Joshua Cooper Remo introduced the idea of the "Beijing Consensus," also known as the Chinese way of economic development. This was seen as an alternative to the ideas of the "Washington Consensus," which were suggested by big international organizations.
Beijing Consensus
The Chinese model, according to experts, is based on three main things:
This model got a lot of attention, especially during the global recession when China was still doing well. Some experts saw it as an alternative to the free-market approach suggested by the Washington Consensus. Some think what worked for China might not work everywhere.
As of 2010, many developing countries were interested in the Chinese model. However, when China's economic growth slowed down in recent times, experts have suggested being careful about blindly following this model.
The Santiago Consensus, introduced by the then World Bank Group President James D. Wolfensohn, serves as an alternative to the Washington Consensus.
Its primary focus is on inclusion, emphasizing not only economic but also social development.
This model is designed to adapt its features to suit the specific needs of local situations, sharing similarities with the concept found in the Beijing Consensus.
The World Bank's approach involves leveraging the power of technology and global cooperation to share the best practices of development worldwide. As part of this strategy, there is a proposal to establish a "knowledge bank."
This approach from the World Bank has inspired governments globally to prioritize aspects of inclusive socio-economic growth.
In the case of India, the launch of the third generation of economic reforms in 2002 aimed to make the benefits of reforms more inclusive.
National income is the total value of all the goods and services manufactured by the residents of the country, in a year., within its domestic boundaries or outside. It is the net amount of income of the citizens by production in a year. There are four main concepts involved: GDP, NDP, GNP, and NNP. Let's take a straightforward look at each.
Gross Domestic Product (GDP) is the total value of all goods and services produced in a country within a year. For India, this year runs from April 1 to March 31.
To calculate GDP, we add up spending on national consumption, investment, government spending, and the trade balance (exports minus imports). This helps us account for goods and services produced within the country and those exported.
Gross Domestic Product (GDP)
Understanding the terms used in GDP:
Uses of GDP:
Net Domestic Product (NDP) is like the GDP, but we adjust it by considering the wear and tear, or "depreciation," that happens to assets during production. All things, except humans, experience this wear and tear over time.
Net Domestic Product(NDP)Governments set rates for how assets depreciate, like houses or machinery. For example, a residential house might have a 1% depreciation rate per year. This is done to account for the loss in value over time.
NDP is calculated by subtracting the depreciation from GDP: NDP = GDP – Depreciation.
There are two main uses of NDP:
However, NDP is not used for comparing economies globally because different countries have different rates of depreciation. Rates can be logical, based on asset durability, or sometimes influenced by government policies to boost certain sectors. So, depreciation is not a universal measure for comparing economies worldwide.
Gross National Product (GNP) is like GDP, but it includes the country's income from abroad. This means it accounts for economic activities that cross borders.
Gross National Product(GNP)
Income from Abroad has three components: Private Remittances, Interest on External Loans, and External Grants. The balance of these components determines if a country is a net gainer or loser. In India's case, it's been negative due to trade deficits and interest payments on foreign loans.
To calculate GNP (Gross National Product), Income from Abroad is subtracted from GDP (Gross Domestic Product): GNP = GDP - Income from Abroad.
In India, GNP is consistently lower than GDP due to the negative balance in Income from Abroad.
GNP is a more comprehensive measure of national income than GDP, reflecting both internal and external economic strength.
Net National Product(NNP)
The formula to derive NNP can be expressed in two ways:
NNP = GNP - Depreciation: This version emphasizes the subtraction of depreciation directly from GNP.
NNP = GDP + Income from Abroad - Depreciation: An alternative formula that incorporates the balance of income from abroad along with depreciation.
Key points about NNP:
Purity of National Income: NNP is considered the purest form of national income, capturing the net value of economic output available to the nation.
Comparison with Other Measures: While GDP, NDP, and GNP are all considered national incomes, NNP is unique in its approach.
Per Capita Income (PCI): When NNP is divided by the total population of a nation, it gives the per capita income (PCI). PCI is a crucial indicator, representing the average income per person per year. The comparison of PCI among nations is influenced by the rates of depreciation they apply to different assets.
Impact of Depreciation Rates: Different nations may have varying rates of depreciation for their assets. The rates of depreciation they choose can impact the international comparison of national incomes, especially when assessed by organizations like the International Monetary Fund (IMF), World Bank (WB), and Asian Development Bank (ADB).
Revision of National Accounts: The Central Statistics Office (CSO) revised the 'base year' and the methodology for calculating national accounts in January 2015. This revision aimed to enhance the accuracy and relevance of economic data.
When we talk about the income of a country, it can be calculated in two ways: "factor cost" or "market cost." Let's simplify the difference:
Factor Cost:
Market Cost:
India's Approach:
Key Change: This shift aligns India with global practices, making it easier to calculate national income, especially after the implementation of the Goods and Services Tax (GST).
National Accounts Changes in 2015: A Simplified Overview
In January 2015, the Central Statistics Office (CSO) made important updates to the National Accounts, bringing about two main changes:
Base Year Revision: The base year was shifted from 2004-05 to 2011-12. This adjustment followed the advice of the National Statistical Commission (NSC), which recommended revising the base year for all economic indices every 5 years.
Methodology Alignment: The methodology used for calculating National Accounts was revised to align with the System of National Accounts (SNA), 2008—a globally recognized standard.
Major Changes in National Accounts Revision (2015): Simplified Overview
The 2015 revision of National Accounts brought several significant changes, making the system more comprehensive and aligned with international standards. Here are the key modifications:
Headline Growth Rate Measurement: The headline growth rate is now measured by Gross Domestic Product (GDP) at constant market prices. This aligns with international practices. Previously, growth was measured using the growth rate in GDP at factor cost and at constant prices.
Sector-wise Estimates: (CE) refers to the compensation of employees, (OS) stands for operating surplus, (MI) is mixed-income, (CFC) represents consumption of fixed capital or depreciation,(GVA) represents Gross Value Added.
Better Insight into Local Governance: There's an improved understanding of the financial activities of local governments and self-governing bodies. Approximately 60% of the money they receive and spend is now accounted for, giving us a clearer view of their financial operations.
Methods of Calculating Economic Output: We estimate a country's economic output using two main approaches: demand side and supply side.
Demand Side vs Supply Side
Supply Side:
Demand Side:
Comparison:
The government is currently exploring a shift from the fixed-base method to the chain-base method for calculating GDP. In this new approach, GDP estimates are compared with the previous year instead of a fixed base year that undergoes revision every five years. The fixed-base method, currently in use, has limitations as it maintains unchanged weights assigned to economic activities, irrespective of structural changes, and does not consider relative price changes and their impact on demand.
The chain-base method offers several advantages over the existing approach.
