Chapter 5 introduces economic development, focusing on the population as a whole. This includes living standards, poverty, and comparing developed and less developed economies. Living standards refer to all factors contributing to a person's well-being and happiness. The government cares about living standards as a macroeconomic concern. Living standards are primarily measured by GDP per capita, which indicates the average income per person in an economy.
GDP per capita is a useful measure because it indicates total production and material well-being, correlates with job creation, and the data is readily available. However, GDP has limitations: it doesn't account for purchasing power with income, doesn't consider technological changes, excludes unpaid work (like volunteering), and overlooks non-economic factors important for well-being such as leisure, health, education, and environmental quality. These limitations highlight why GDP alone is insufficient for a comprehensive understanding of living standards.
The Human Development Index (HDI), developed by the United Nations, is an alternative measure of living standards, ranging from 0 to 1. It considers three main factors: income index (average national income or GNI per capita), education index (years of schooling), and healthcare index (life expectancy from birth). HDI benefits include considering major indicators of living standards (income, education, health), recognizing social factors beyond just output, providing a reliable global comparison, and being produced by a recognized organization. Its limitations include combining disparate indicators, not reflecting income inequality within countries, neglecting other important factors like environmental quality and access to clean water, and potentially lacking complete information for all countries.
Differences in living standards exist both within and between countries. Within a country, regional variances in income and consumption, driven by job types (e.g., manufacturing vs. service industries in major cities) and varying government provisions across states, create disparities. Between countries, differences arise from industrial productivity (linking output to employment and income), availability of scarce resources (like oil) that drive demand and output, citizens' ability to pay taxes (which government uses for infrastructure or welfare, contrasting with corruption), and external factors like war, crime, and natural disasters.
Poverty is defined in two ways: absolute poverty (inability to afford basic necessities like water, food, shelter, healthcare) and relative poverty (having fewer resources than others in the same society, often indicating income inequality). Causes of poverty include unemployment, low education levels (leading to unskilled labor), large family sizes (stretching income), age (older individuals may have health problems affecting work), poor government support (lack of welfare programs), poor health impeding work, and overpopulation (straining scarce resources and increasing prices). Government policies to address poverty involve reducing unemployment (e.g., through expansionary fiscal policy), implementing progressive tax systems, introducing welfare services, and improving the quantity and quality of education (supply-side policies).
Population is a critical economic factor, with governments aiming for stable sizes. Birth rates are the average number of children born per year compared to the total population. Factors affecting birth rates include living standards (poor standards often lead to higher birth rates due to infant mortality fears and children assisting families), contraception use (countries with accessible contraception and legalized abortion tend to have lower birth rates), customs and religion (some beliefs prohibit contraception, leading to larger families), and changes in female employment (women in the labor force may delay or have fewer children). Death rates are the number of people who die each year per 1,000 population. Similar to birth rates, death rates are influenced by living standards, medical advances and healthcare technology, and natural disasters and wars. Migration, driven by desires for better living standards, employment opportunities, and suitable climates, also affects population.
Population structure refers to age and gender distribution. Age distribution (number of people per age group) is crucial, as a workforce primarily in their mid-20s to mid-30s benefits the economy. An aging population has consequences such as a declining workforce, increased government spending on welfare and healthcare for the elderly, higher demand for products catering to older people, and potential needs for investment in mobility solutions. Gender distribution can impact birth rates; for instance, a higher proportion of females may encourage higher birth rates, influencing population growth. An increasing population size can lead to a larger domestic market, increased labor supply, and a need for more capital goods, but it can also cause a fall in productivity if resources are limited relative to the population. Economic development ultimately refers to the increase in economic welfare through growth in productive scale and wealth, encompassing improved living standards, reduced poverty, and a balanced population size, all of which are interconnected components of a developed economy.
