Why Do We Use GDP To Measure Economic Welfare?

GDP has always been an indicator of output rather than welfare. It calculates the worth of goods and services generated for final consumption, both private and public, in the present and future, using current prices. (Future consumption is taken into account because GDP includes investment goods output.) It is feasible to calculate the increase of GDP over time or the disparities between countries across distance by converting to constant pricing.

Despite the fact that GDP is not a measure of human welfare, it can be viewed as a component of it. The quantity of products and services available to the typical person obviously adds to overall welfare, while it is by no means the only factor. So, among health, equality, and human rights, a social welfare function might include GDP as one of its components.

GDP is also a measure of human well-being. GDP per capita is highly associated with other characteristics that are crucial for welfare in cross-country statistics. It has a positive relationship with life expectancy and a negative relationship with infant mortality and inequality. Because parents are naturally saddened by the loss of their children, infant mortality could be viewed as a measure of happiness.

Figures 1-3 exhibit household consumption per capita (which closely tracks GDP per capita) against three indices of human welfare for large sampling of nations. They show that countries with higher incomes had longer life expectancies, reduced infant mortality, and lesser inequality. Of course, correlation does not imply causation, however there is compelling evidence that more GDP per capita leads to better health (Fogel 2004).

Why is GDP a useful indicator of economic prosperity?

The Gross Domestic Product (GDP) measures both the economy’s entire income and its total expenditure on goods and services. As a result, GDP per person reveals the typical person’s income and expenditure in the economy. Because most people would prefer to have more money and spend it more, GDP per person appears to be a natural measure of the average person’s economic well-being.

However, some people question the accuracy of GDP as a measure of happiness. Senator Robert F. Kennedy, who ran for president in 1968, delivered a powerful condemnation of such economic policies:

does not allow for our children’s health, the quality of their education, or the enjoyment of their play. It excludes the beauty of our poetry, the solidity of our marriages, the wit of our public discourse, and the honesty of our elected officials. It doesn’t take into account our bravery, wisdom, or patriotism. It can tell us everything about America except why we are glad to be Americans, and it can measure everything but that which makes life meaningful.

The truth is that a high GDP does really assist us in leading happy lives. Our children’s health is not measured by GDP, yet countries with higher GDP can afford better healthcare for their children. The quality of their education is not measured by GDP, but countries with higher GDP may afford better educational institutions. The beauty of our poetry is not measured by GDP, but countries with higher GDP can afford to teach more of their inhabitants to read and love poetry. GDP does not take into consideration our intelligence, honesty, courage, knowledge, or patriotism, yet all of these admirable qualities are simpler to cultivate when people are less anxious about being able to purchase basic requirements. In other words, while GDP does not directly measure what makes life valuable, it does measure our ability to access many of the necessary inputs.

However, GDP is not a perfect indicator of happiness. Some factors that contribute to a happy existence are not included in GDP. The first is leisure. Consider what would happen if everyone in the economy suddenly began working every day of the week instead of relaxing on weekends. GDP would rise as more products and services were created. Despite the increase in GDP, we should not assume that everyone would benefit. The loss of leisure time would be countered by the gain from producing and consuming more goods and services.

Because GDP values commodities and services based on market prices, it ignores the value of practically all activity that occurs outside of markets. GDP, in particular, excludes the value of products and services generated in one’s own country. The value of a delicious meal prepared by a chef and sold at her restaurant is included in GDP. When the chef cooks the same meal for her family, however, the value she adds to the raw ingredients is not included in GDP. Child care supplied in daycare centers is also included in GDP, although child care provided by parents at home is not. Volunteer labor also contributes to people’s well-being, but these contributions are not reflected in GDP.

Another factor that GDP ignores is environmental quality. Consider what would happen if the government repealed all environmental rules. Firms might therefore generate goods and services without regard for the pollution they produce, resulting in an increase in GDP. However, happiness would most likely plummet. The gains from increased productivity would be more than outweighed by degradation in air and water quality.

GDP also has no bearing on income distribution. A society with 100 persons earning $50,000 per year has a GDP of $5 million and, predictably, a GDP per person of $50,000. So does a society in which ten people earn $500,000 and the other 90 live in poverty. Few people would consider those two scenarios to be comparable. The GDP per person informs us what occurs to the average person, yet there is a wide range of personal experiences behind the average.

Finally, we might conclude that GDP is a good measure of economic well-being for the majority of purposes but not all. It’s critical to remember what GDP covers and what it excludes.

Is GDP a measure of happiness?

In reality, “GDP counts everything but that which makes life meaningful,” as Senator Robert F. Kennedy memorably stated. Health, education, equality of opportunity, the state of the environment, and many other measures of quality of life are not included in the number. It does not even assess critical features of the economy, such as its long-term viability, or whether it is on the verge of collapsing. What we measure, however, is important because it directs our actions. The military’s emphasis on “body counts,” or the weekly calculation of the number of enemy soldiers killed, gave Americans a hint of this causal link during the Vietnam War. The US military’s reliance on this morbid statistic led them to conduct operations with no other goal than to increase the body count. The focus on corpse numbers, like a drunk seeking for his keys under a lamppost (because that’s where the light is), blinded us to the greater picture: the massacre was enticing more Vietnamese citizens to join the Viet Cong than American forces were killing.

Now, a different corpse count, COVID-19, is proving to be an alarmingly accurate indicator of society performance. There isn’t much of a link between it and GDP. With a GDP of more than $20 trillion in 2019, the United States is the world’s richest country, implying that we have a highly efficient economic engine, a race vehicle that can outperform any other. However, the United States has had almost 600,000 deaths, but Vietnam, with a GDP of $262 billion (and only 4% of the United States’ GDP per capita), has had less than 500 to far. This less fortunate country has easily defeated us in the fight to save lives.

In fact, the American economy resembles a car whose owner saved money by removing the spare tire, which worked fine until he got a flat. And what I call “GDP thinking”the mistaken belief that increasing GDP will improve well-being on its owngot us into this mess. In the near term, an economy that uses its resources more efficiently has a greater GDP in that quarter or year. At a microeconomic level, attempting to maximize that macroeconomic measure translates to each business decreasing costs in order to obtain the maximum possible short-term profits. However, such a myopic emphasis inevitably jeopardizes the economy’s and society’s long-term performance.

The health-care industry in the United States, for example, took pleasure in efficiently using hospital beds: no bed was left empty. As a result, when SARS-CoV-2 arrived in the United States, there were only 2.8 hospital beds per 1,000 people, significantly fewer than in other sophisticated countries, and the system was unable to cope with the rapid influx of patients. In the short run, doing without paid sick leave in meat-packing facilities improved earnings, which raised GDP. Workers, on the other hand, couldn’t afford to stay at home when they were sick, so they went to work and spread the sickness. Similarly, because China could produce protective masks at a lower cost than the US, importing them enhanced economic efficiency and GDP. However, when the epidemic struck and China required considerably more masks than usual, hospital professionals in the United States were unable to meet the demand. To summarize, the constant pursuit of short-term GDP maximization harmed health care, increased financial and physical insecurity, and weakened economic sustainability and resilience, making Americans more exposed to shocks than inhabitants of other countries.

In the 2000s, the shallowness of GDP thinking had already been apparent. Following the success of the United States in raising GDP in previous decades, European economists encouraged their leaders to adopt American-style economic strategies. However, as symptoms of trouble in the US banking system grew in 2007, France’s President Nicolas Sarkozy learned that any leader who was solely focused on increasing GDP at the expense of other indices of quality of life risked losing the public’s trust. He asked me to chair an international commission on measuring economic performance and social progress in January 2008. How can countries improve their metrics, according to a panel of experts? Sarkozy reasoned that determining what made life valuable was a necessary first step toward improving it.

Our first report, provocatively titled Mismeasuring Our Lives: Why GDP Doesn’t Add Up, was published in 2009, just after the global financial crisis highlighted the need to reassess economic orthodoxy’s key premises. The Organization for Economic Co-operation and Development (OECD), a think tank that serves 38 advanced countries, decided to follow up with an expert panel after it received such excellent feedback. We confirmed and enlarged our original judgment after six years of dialogue and deliberation: GDP should be dethroned. Instead, each country should choose a “dashboard”a collection of criteria that will guide it toward the future that its citizens desire. The dashboard would include measures for health, sustainability, and any other values that the people of a nation aspired to, as well as inequality, insecurity, and other ills that they intended to reduce, in addition to GDP as a measure of market activity (and no more).

These publications have aided in the formation of a global movement toward improved social and economic indicators. The OECD has adopted the method in its Better Life Initiative, which recommends 11 indicators and gives individuals a way to assess them in relation to other countries to create an index that measures their performance on the issues that matter to them. The World Bank and the International Monetary Fund (IMF), both long-time proponents of GDP thinking, are now paying more attention to the environment, inequality, and the economy’s long-term viability.

This method has even been adopted into the policy-making frameworks of a few countries. In 2019, New Zealand, for example, incorporated “well-being” measures into the country’s budgeting process. “Success is about making New Zealand both a terrific location to make a livelihood and a fantastic place to create a life,” said Grant Robertson, the country’s finance minister. This focus on happiness may have contributed to the country’s victory over COVID-19, which appears to have been contained to around 3,000 cases and 26 deaths in a population of over five million people.

What is the most accurate technique to assess economic well-being?

Question from the audience. What exactly is economic well-being? Could you perhaps explain how this affects the economy?

Economic welfare is defined as the amount of prosperity and the quality of living standards in a given economy. Economic well-being can be quantified using a range of parameters, including GDP and other measures that indicate population well-being (such as literacy, number of doctors, levels of pollution e.t.c)

Economic well-being is a broad notion that is difficult to define. It essentially relates to how well people are performing. Economic well-being is commonly expressed as a ratio of real income to real GDP. An increase in real output and real incomes indicates that individuals are better off, and hence that economic wellbeing has improved.

Economic well-being, on the other hand, will be concerned with more than just income levels. People’s living standards, for example, are influenced by issues such as health-care access and environmental concerns such as traffic and pollution. These aspects of quality of life are crucial in determining economic well-being.

Factors influencing economic welfare

  • Housing Housing that is unaffordable despite a high salary reduces economic well-being. Housing that is both good and affordable is critical to economic well-being.
  • Life expectancy and quality of life – access to healthcare, as well as healthy behaviors, such as obesity and smoking rates are all factors to consider.
  • Economic expansion can lead to greater pollution, which is harmful to people’s health and living conditions.
  • Leisure time high pay as a result of working extremely long hours reduces economic well-being. Leisure has monetary worth.

Economics is concerned with utility concepts. A consumer’s satisfaction/happiness is represented by utility. If you spend 10 for a CD, for example, you are likely getting at least 10’s worth of usefulness from the item.

This is a discipline of economics concerned with establishing the best resource distribution in society. It is interested in both allocative and social efficiency.

Measure of economic welfare (MEW)

This was created in 1972 as a substitute for GDP. William Nordhaus and James Tobin came up with the idea. (WD Nordhaus and J Tobin) (1972) Is Growth No Longer Necessary?

It modifies the definition of total national output to only include products that contribute to economic well-being.

  • The underground economy’s economic output (not measured by official GDP statistics)

Index of Human Development Index HDI

This is a metric that looks at the many options available to people. It is a composite measure that takes into account three key criteria that influence living standards: income, life expectancy, and education. The three elements are as follows:

A rating of 1 is assigned to the highest level of human development. A value close to 0 is assigned to low levels of human development.

Well-being index

The ONS developed this measure of economic well-being and life satisfaction. It takes into account our health, relationships, education, and talents, as well as what we do, where we live, our finances, and the environment. It contains both positive and negative data, as well as surveys and questionnaires; it also employs a novel technique and is experimenting with economic data.

Is GDP the most accurate indicator of economic health?

GDP is a good indicator of an economy’s size, and the GDP growth rate is perhaps the best indicator of economic growth, while GDP per capita has a strong link to the trend in living standards over time.

How do economists determine the rate of economic growth?

Obviously, not all developed countries share all of these qualities in the same way. Some of you may even criticize the inclusion of certain elements in the above list, citing nations (or regions within them) where, for example, crime and unemployment appear to be high, or pointing out that not everyone has access to adequate public services, housing, and so on. Some of these issues are definitely debatable. For example, crime rates in rural areas of many developing countries, where the majority of people live, are frequently lower than in some of the developed countries’ metropolitan population centers. Nonetheless, the traits that distinguish countries that are economically developed from those that are not are probably quite well represented in the preceding list.

Economic growth

You’ll notice, as you did with the last question, that the stated attributes speak more about goals than the methods or mechanisms for accomplishing them. So, what motivates a country to achieve these objectives? The conventional wisdom, as supported by most governments, large international organizations, and the economists who advise them, is that economic development is a big part of the solution.

Economic growth, on the other hand, can go many different directions, and not all of them are sustainable. Given the finite nature of the world and its resources, many contend that any sort of economic expansion is ultimately unsustainable. These discussions will be postponed. For the time being, let us consider what economic growth is and how it is assessed.

Economists typically quantify economic growth in terms of gross domestic product (GDP) or related metrics derived from the GDP calculation, such as gross national product (GNP) or gross national income (GNI). GDP is estimated using annual data on revenues, expenditures, and investment for each sector of the economy from a country’s national accounts. It is feasible to estimate a country’s total income earned in any given year (GDP) or the total income earned by its population using these facts (GNP or GNI).

GNP is calculated by adjusting GDP to include repatriated money earned overseas and excluding expatriated income generated by foreigners in the United States. In countries with large inflows and outflows of this nature, GNP may be a better measure of a country’s income than GDP.

The income approach, as the name implies, evaluates people’s earnings, while the output approach assesses the value of the goods and services used to create these earnings, and the expenditure approach assesses people’s spending on goods and services. Each of these ways should, in theory, provide the same effect, so if the economy’s output rises, incomes and expenditures should rise by the same amount.

Economic growth is commonly expressed as a percentage rise in real GDP over a given year. Real GDP is computed by adjusting nominal GDP for inflation, which would otherwise make growth rates appear considerably larger than they are, particularly during high inflation times.

Short-term versus long-term growth

There must be a differentiation made between short-term and long-term growth rates. Short-term growth rates move in lockstep with the business cycle, which is to be expected. This may be seen in Figures 1.2.1 and 1.2.2, which show GDP growth in the United States from 1930 to 2003.

What are the drawbacks of using GDP to assess economic well-being?

It does, however, have some significant drawbacks, including: Non-market transactions are excluded. The failure to account for or depict the extent of income disparity in society. Failure to indicate whether or not the country’s growth pace is sustainable.

Is GDP a reliable indicator of economic well-being in class 12?

Since GDP accounts for both the economy’s total revenue and expenditure on goods and services, one would wonder whether GDP is a good indicator of economic well-being. GDP, on the other hand, cannot be regarded as a perfect indicator of economic well-being.

What is the purpose of GDP?

Gross domestic product (GDP) is the total monetary value, or market value, of finished products and services produced inside a country over a given time period, usually a year or quarter. It’s a measure of domestic production in this sense, and it can be used to assess a country’s economic health.

Nominal GDP vs. Real GDP

Depending on how it’s computed, GDP is usually expressed in two ways: nominal GDP and real GDP.

Nominal GDP analyzes broad changes in an economy’s value over time by accounting for current market prices without taking deflation or inflation into consideration. Real GDP takes into account inflation and the overall growth in price levels, making it a more accurate measure of a country’s economic health.

Because it provides more value and insight, this paper will primarily focus on real GDP.

Why is real GDP a better indicator of economic change over time?

Economists track real gross domestic product (GDP) to figure out how fast a country’s economy is developing without being distorted by inflation. They can more precisely estimate growth with the real GDP number.
