• Real GDP Year 2 = Nominal GDP Year 2 / (1 + Inflation rate)

• Real GDP Year 2 = 1,060 / (1 + 0.02) = $1,039.22 billion

b. Step 2: Calculate the real GDP growth rate

• Growth rate = (Real GDP Year 2 - Nominal GDP Year 1) / Nominal GDP

Year 1 × 100

• Growth rate = (1,039.22 - 1,000) / 1,000 × 100 = 3.922%

c. The real GDP growth rate is approximately 3.92%

357. Discuss the limitations of using GDP as a measure of economic well-being. What

alternative measures have been proposed, and how do they address these limitations?

Solution:

a. Limitations of GDP:

• Doesn’t account for income distribution

• Ignores non-market activities (e.g., household work)

• Doesn’t consider environmental degradation

• Fails to capture quality of life aspects

• Doesn’t account for the sustainability of growth

b. Alternative measures:

• Human Development Index (HDI):

– Incorporates life expectancy, education, and income

– Addresses quality of life aspects

• Genuine Progress Indicator (GPI):

– Accounts for environmental and social factors

– Subtracts negative factors (e.g., pollution) from economic growth

• Gross National Happiness (GNH):

– Measures psychological well-being, health, education, culture, and

living standards

– Emphasizes holistic development

• Sustainable Development Goals (SDGs):

– Address various aspects of well-being and sustainability

– Provide a comprehensive framework for development

c. These alternatives address GDP limitations by:

• Incorporating non-economic factors

• Considering sustainability and environmental impact

• Focusing on broader aspects of human well-being

periods
