3. What are the pros and cons of using GDP as a measure of a nation's well-being?
GDP provides a better analysis or measure of economy activity through its growth rate and changes in an economy than any other existing measure. It summarizes a whole range of economic information in and determines the comparative strengths and weaknesses of various sectors.
GDP serve as accurate barometer of the business climate, where it provides the government and business useful information to adjust in different kinds of contingency problems like recession and depression.
GDP serve as a simple proxy for social and economic welfare.
G DP does not include non-market activities. These activities are based on production and consumption that occur outside the market economy that does not have a price attached like unpaid house workers, volunteer work, barter and the illegal drug trade.
It does not include domestic household products or black market.
It does not consider how the wealth of a nation is distributed equally. For example , GDP provides an estimate of each person share of the market economy but, in reality some people share of the economy is greater than others. This level of unequal distribution of incomes and consumption and the incidence of poverty cannot be determined by tracking the GDP.
Some GDP measured expenditures do not contribute to Economic Welfare. It does not account for any welfare loss or any negative events that results from an event such as a natural disaster environmental cleanup or reconstruction effort contributes to welfare and the GDP.
It does not accurately reflect the wellbeing and the living standards of people. The performance of few top companies can skew the GDP figure (It is a mean). E.g. : While India is the 5 th largest economy in terms of GDP, a significant number of people still earn less than $2 a day and lead a difficult life.
