The United States is a highly developed mixed economy. It is the world's largest economy by nominal GDP; it is also the second largest by purchasing power parity (PPP), behind China. It has the world's sixth highest per capita GDP (nominal) and the eighth highest per capita GDP (PPP) as of 2024. The U.S. accounted for 26% of the global economy in 2023 in nominal terms, and about 15.5% in PPP terms. The U.S. dollar is the currency of record most used in international transactions and is the world's reserve currency, backed by a large U.S. treasuries market, its role as the reference standard for the petrodollar system, and its linked eurodollar. Several countries use it as their official currency and in others it is the de facto currency. Since the end of World War II, the economy has achieved relatively steady growth, low unemployment and inflation, and rapid advances in technology.
The "Miracle of Chile" was a term used by economist Milton Friedman to describe the reorientation of the Chilean economy in the 1980s and the effects of the economic policies applied by a large group of Chilean economists who collectively came to be known as the Chicago Boys, having studied at the University of Chicago where Friedman taught. He said the "Chilean economy did very well, but more importantly, in the end the central government, the military junta, was replaced by a democratic society. So the really important thing about the Chilean business is that free markets did work their way in bringing about a free society." The junta to which Friedman refers was a military government that came to power in a 1973 coup d'état, which came to an end in 1990 after a democratic 1988 plebiscite removed Augusto Pinochet from the presidency.
Development economics is a branch of economics that deals with economic aspects of the development process in low- and middle- income countries. Its focus is not only on methods of promoting economic development, economic growth and structural change but also on improving the potential for the mass of the population, for example, through health, education and workplace conditions, whether through public or private channels.
The Index of Economic Freedom is an annual index and ranking created in 1995 by The Heritage Foundation and The Wall Street Journal to measure the degree of economic freedom in the world's nations. The creators of the index assert that they take an approach inspired by Adam Smith's The Wealth of Nations, that "basic institutions that protect the liberty of individuals to pursue their own economic interests result in greater prosperity for the larger society".
Economic freedom, or economic liberty, refers to the agency of people to make economic decisions. This is a term used in economic and policy debates as well as in the philosophy of economics. One approach to economic freedom comes from the liberal tradition emphasizing free markets, free trade, and private property. Another approach to economic freedom extends the welfare economics study of individual choice, with greater economic freedom coming from a larger set of possible choices. Other conceptions of economic freedom include freedom from want and the freedom to engage in collective bargaining.
Economic inequality is an umbrella term for a) income inequality or distribution of income, b) wealth inequality or distribution of wealth, and c) consumption inequality. Each of these can be measured between two or more nations, within a single nation, or between and within sub-populations.
In economics, income distribution covers how a country's total GDP is distributed amongst its population. Economic theory and economic policy have long seen income and its distribution as a central concern. Unequal distribution of income causes economic inequality which is a concern in almost all countries around the world.
Poverty reduction, poverty relief, or poverty alleviation is a set of measures, both economic and humanitarian, that are intended to permanently lift people out of poverty. Measures, like those promoted by Henry George in his economics classic Progress and Poverty, are those that raise, or are intended to raise, ways of enabling the poor to create wealth for themselves as a conduit of ending poverty forever. In modern times, various economists within the Georgism movement propose measures like the land value tax to enhance access to the natural world for all. Poverty occurs in both developing countries and developed countries. While poverty is much more widespread in developing countries, both types of countries undertake poverty reduction measures.
Poverty in the entirety of Australia refers to the incidence of relative poverty in Australia and its measurement. Relative income poverty is measured as the percentage of the population that earns less than the median wage of the working population.
Child poverty refers to the state of children living in poverty and applies to children from poor families and orphans being raised with limited or no state resources. UNICEF estimates that 356 million children live in extreme poverty. It is estimated that 1 billion children lack at least one essential necessity such as housing, regular food, or clean water. Children are more than twice as likely to live in poverty as adults and the poorest children are twice as likely to die before the age of 5 compared to their wealthier peers.
International inequality refers to inequality between countries, as compared to global inequality, which is inequality between people across countries. International inequality research has primarily been concentrated on the rise of international income inequality, but other aspects include educational and health inequality, as well as differences in medical access. Reducing inequality within and among countries is the 10th goal of the UN Sustainable Development Goals and ensuring that no one is left behind is central to achieving them. Inequality can be measured by metrics such as the Gini coefficient.
Poverty in India remains a major challenge despite overall reductions in the last several decades as its economy grows. According to an International Monetary Fund paper, extreme poverty, defined by the World Bank as living on US$1.9 or less in purchasing power parity (PPP) terms, in India was as low as 0.8% in 2019, and the country managed to keep it at that level in 2020 despite the unprecedented COVID-19 outbreak. According to the World Bank, India experienced a significant decline in the prevalence of extreme poverty from 22.5% in 2011 to 10.2% in 2019. A working paper of the bank said rural poverty declined from 26.3% in 2011 to 11.6% in 2019. The decline in urban areas was from 14.2% to 6.3% in the same period. The poverty level in rural and urban areas went down by 14.7 and 7.9 percentage points, respectively. According to United Nations Development Programme administrator Achim Steiner, India lifted 271 million people out of extreme poverty in a 10-year time period from 2005–2006 to 2015–2016. A 2020 study from the World Economic Forum found "Some 220 million Indians sustained on an expenditure level of less than Rs 32 / day—the poverty line for rural India—by the last headcount of the poor in India in 2013."
Income inequality has fluctuated considerably in the United States since measurements began around 1915, moving in an arc between peaks in the 1920s and 2000s, with a 30-year period of relatively lower inequality between 1950 and 1980.
Poverty in Canada refers to the state or condition in which a person or household lacks essential resources—financial or otherwise—to maintain a modest standard of living in their community.
A number of indicators of economic freedom are available for review. They differ in the methods by which they have been constructed, the purposes to which they have been put, and the conception of economic freedom they embody.
In the United States, poverty has both social and political implications. In 2020, there were 37.9 million people in poverty. Some of the many causes include income, inequality, inflation, unemployment, debt traps and poor education. The majority of adults living in poverty are employed and have at least a high school education. Although the US is a relatively wealthy country by international standards, it has a persistently high poverty rate compared to other developed countries due in part to a less generous welfare system.
Economic globalization is one of the three main dimensions of globalization commonly found in academic literature, with the two others being political globalization and cultural globalization, as well as the general term of globalization. Economic globalization refers to the widespread international movement of goods, capital, services, technology and information. It is the increasing economic integration and interdependence of national, regional, and local economies across the world through an intensification of cross-border movement of goods, services, technologies and capital. Economic globalization primarily comprises the globalization of production, finance, markets, technology, organizational regimes, institutions, corporations, and people.
Effects of income inequality, researchers have found, include higher rates of health and social problems, and lower rates of social goods, a lower population-wide satisfaction and happiness and even a lower level of economic growth when human capital is neglected for high-end consumption. For the top 21 industrialised countries, counting each person equally, life expectancy is lower in more unequal countries. A similar relationship exists among US states.
Sustainable Development Goal 10 is about reduced inequality and is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The full title is: "Reduce inequality within and among countries".
