Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced and rendered in a specific time period by a country or countries. GDP is often used to measure the economic health of a country or region. Several national and international economic organizations maintain definitions of GDP, such as the OECD and the International Monetary Fund.
In economics, a recession is a business cycle contraction that occurs when there is a period of broad decline in economic activity. Recessions generally occur when there is a widespread drop in spending. This may be triggered by various events, such as a financial crisis, an external trade shock, an adverse supply shock, the bursting of an economic bubble, or a large-scale anthropogenic or natural disaster. There is no official definition of a recession, according to the IMF.
Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies. PPP is effectively the ratio of the price of a market basket at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of tariffs, and other transaction costs.
The world economy or global economy is the economy of all humans in the world, referring to the global economic system, which includes all economic activities conducted both within and between nations, including production, consumption, economic management, work in general, financial transactions and trade of goods and services. In some contexts, the two terms are distinct: the "international" or "global economy" is measured separately and distinguished from national economies, while the "world economy" is simply an aggregate of the separate countries' measurements. Beyond the minimum standard concerning value in production, use and exchange, the definitions, representations, models and valuations of the world economy vary widely. It is inseparable from the geography and ecology of planet Earth.
This is the Economic history of the Indian subcontinent. It includes the economic timeline of the region, from the ancient era to the present, and briefly summarizes the data presented in the Economic history of India and List of regions by past GDP (PPP) articles.
The World Economy: Historical Statistics is a landmark book by Angus Maddison. Published in 2004 by the OECD Development Centre, it studies the growth of populations and economies across the centuries: not just the world economy as it is now, but how it was in the past.
This article lists current estimates of the world population in history. In summary, estimates for the progression of world population since the Late Middle Ages are in the following ranges:
Angus Maddison was a distinguished British economist specialising in quantitative macro economic history, including the measurement and analysis of economic growth and development.
Branko Milanović is a Serbian-American economist. He is most known for his work on income distribution and inequality.
This article includes a list of China's historical gross domestic product (GDP) values, the market value of all final goods and services produced by a nation in a given year. The GDP dollar estimates presented here are either calculated at market or government official exchange rates (nominal), or derived from purchasing power parity (PPP) calculations. This article also includes historical GDP growth.
The Penn World Table (PWT) is a set of national-accounts data developed and maintained by scholars at the University of California, Davis and the Groningen Growth Development Centre of the University of Groningen to measure real GDP across countries and over time. Successive updates have added countries, years (1950-2019), and data on capital, productivity, employment and population. The current version of the database, version 10, thus allows for comparisons of relative GDP per capita, as a measure of standard of living, the productive capacity of economies and their productivity level. Compared to other databases, such as the World Bank's World Development Indicators, the time period covered is larger and there is more data that is useful for comparing productivity across countries and over time.
This historical list of the ten largest countries by GDP compiled by British economist Angus Maddison shows how much the membership and rankings of the world's ten largest economies has changed.
Leprechaun economics was a term coined by economist Paul Krugman to describe the 26.3 per cent rise in Irish 2015 GDP, later revised to 34.4 per cent, in a 12 July 2016 publication by the Irish Central Statistics Office (CSO), restating 2015 Irish national accounts. At that point, the distortion of Irish economic data by tax-driven accounting flows reached a climax. In 2020, Krugman said the term was a feature of all tax havens.
The Total Economy Database describes itself as "a comprehensive database with annual data covering GDP, population, employment, hours, labor quality, capital services, labor productivity, and Total Factor Productivity for 123 countries in the world".
In 2015, the Central Statistics Office of the Government of India made a number of changes to the way it calculated the gross domestic product of India, including a change in the base year relative to which calculations are done. This change was known as the 2015 India GDP rebasing or just the rebasing.
In November 2010, the government of Ghana made a number of changes to the way it calculated GDP, resulting in a 60% upward change in its estimate. The change led to discussion of the accuracy of GDP estimates, particularly in the context of Africa. It was also the first of many rebasings undertaken by African economies, most of which led to significant upward revisions in their estimates of GDP.
