Extract B states: 'adjusting for PPP reveals a different picture of local purchasing power.'
Explain the term 'Purchasing Power Parity (PPP)' and analyse two indicators (other than GDP per capita) that can be used to assess a country's standard of living.
Over the past two decades, member states of the Andean Community (such as Colombia, Peru, Ecuador, and Bolivia) have pursued diverse paths to raise their population's welfare. While resource-rich economies like Bolivia and Ecuador remain highly exposed to commodity price volatility (such as natural gas and oil), diversified services and manufacturing in Colombia and Peru have provided more stable platforms for growth.
Historically, evaluating economic performance relied almost exclusively on Gross Domestic Product (GDP). However, economists increasingly argue that raw output statistics fail to capture the actual quality of life. Issues such as the informal economy (which accounts for over 50% of employment in some Andean cities), income inequality, and environmental degradation are often masked by rising headline GDP figures.
To address these limitations, international agencies use metrics like the Human Development Index (HDI) and Purchasing Power Parity (PPP) adjustments to make more meaningful cross-border comparisons. For instance, while Peru's nominal GDP per capita has grown, adjusting for PPP reveals a different picture of local purchasing power. Furthermore, non-income dimensions such as mean years of schooling and life expectancy are crucial. In Colombia, targeted social programs have successfully boosted school enrolment and improved healthcare access in rural areas, leading to a rise in its HDI from 0.650 in 1995 to 0.767 in 2021, compared to Bolivia's rise from 0.535 to 0.692 over the same period.
Ultimately, evaluating standard of living requires looking beyond monetary aggregates to incorporate broader indicators of human development, sustainability, and distribution of income.
