Highlights
This video is the first part of a two-part series on measures of economic performance for A-Level economics, focusing on topics like GDP and economic growth.
Economic growth is defined as the rate of change of output and an increase in the long-term productive potential of a country, measured by the percentage change in real GDP per annum. GDP is the total value of goods and services produced in a country within a year, indicating the standard of living. The video differentiates between total GDP and GDP per capita, and between real GDP (adjusted for inflation) and nominal GDP (not adjusted for inflation), illustrating with an example calculation.
The video introduces Gross National Income (GNI), which includes net overseas interest payments and dividends, and Gross National Product (GNP), which accounts for goods and services produced by a country's citizens both domestically and overseas. These measures are increasingly used due to growing remittances and aid, offering a more comprehensive view than GDP alone.
To accurately compare economic growth over time and between countries, it's crucial to use real per capita figures to account for population changes and inflation. Using real GDP helps strip out the effect of inflation, providing a more accurate picture of increased goods and services rather than just rising prices.
Purchasing Power Parities (PPP) provide an alternative to exchange rates for GDP comparisons by considering the cost of a typical basket of goods in different countries, which helps in comparing living standards more accurately, especially between countries with significant differences in living costs.
Several issues arise when using GDP to compare living standards, including inaccurate data collection, the existence of a hidden or black market, exclusion of home-produced services, errors in inflation rate calculations, differences in calculation methods over time and between countries, and the inclusion of transfer payments. GDP also doesn't account for inequalities in income distribution or improvements in the quality of goods and services over time.
Beyond income, national happiness considers factors like health, social support, freedom, and generosity. The UK's 'measuring national wellbeing report' identifies key drivers of personal well-being, such as health, relationships, and employment status. Research suggests a correlation between real incomes and happiness, especially at lower income levels, but higher incomes do not always lead to increased happiness, illustrating the 'Easterlin paradox'.
