Relationship with nominal GDP
Real GDP is an example of the distinction between real and nominal values in economics. Nominal gross domestic product is defined as the market value of all final goods produced in a geographical region, usually a country; this depends on the quantities of goods and services produced, and their respective prices.
If a set of real GDPs from various years are calculated, each using the quantities from its own year, but all using the prices from the same base year, the differences in those real GDPs will reflect only differences in volume.
An index called the GDP deflator can be obtained by dividing, for each year, the nominal GDP by the real GDP, so that the GDP deflator for the base year will be 100. It gives an indication of the overall level of price change (inflation or deflation) in the economy.

Real GDP growth on an annual basis is the nominal GDP growth rate adjusted for inflation. It is usually expressed as a percentage.
"GDP" may refer to "nominal" or "current" or "historical" GDP, to distinguish it from real GDP. Real GDP is sometimes called "constant" GDP because it is expressed in terms of constant prices. Depending on context, "GDP" may also refer to real GDP.
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. Definitions of GDP are maintained by several national and international economic organizations, such as the OECD and the International Monetary Fund.
Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes national, regional, and global economies. Macroeconomists study topics such as output/GDP and national income, unemployment, price indices and inflation, consumption, saving, investment, energy, international trade, and international finance.
Reaganomics, or Reaganism, were the neoliberal economic policies promoted by U.S. President Ronald Reagan during the 1980s. These policies are characterized as supply-side economics, trickle-down economics, or "voodoo economics" by opponents, including some Republicans, while Reagan and his advocates preferred to call it free-market economics.
In economics, inflation is a general increase in the prices of goods and services in an economy. This is usually measured using the consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices faced by households do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose.
The gross world product (GWP), also known as gross world income (GWI), is the combined gross national income of all the countries in the world. Because imports and exports balance exactly when considering the whole world, this also equals the total global gross domestic product (GDP). According to the World Bank, the 2013 nominal GWP was approximately 75.59 trillion United States dollars. In 2017, according to the CIA's World Factbook, the GWP was around $80.27 trillion in nominal terms and totaled approximately 127.8 trillion international dollars in terms of purchasing power parity (PPP). The per capita PPP GWP in 2017 was approximately 17,500 international dollars according to the World Factbook. According to the World Bank, the 2020 GWP in current dollars was approximately $84.705 trillion.
In economics, the GDP deflator is a measure of the money price of all new, domestically produced, final goods and services in an economy in a year relative to the real value of them. It can be used as a measure of the value of money. GDP stands for gross domestic product, the total monetary value of all final goods and services produced within the territory of a country over a particular period of time.
The government budget balance, also referred to as the general government balance, public budget balance, or public fiscal balance, is the difference between government revenues and spending. For a government that uses accrual accounting the budget balance is calculated using only spending on current operations, with expenditure on new capital assets excluded. A positive balance is called a government budget surplus, and a negative balance is a government budget deficit. A government budget presents the government's proposed revenues and spending for a financial year.
In economics, aggregate demand (AD) or domestic final demand (DFD) is the total demand for final goods and services in an economy at a given time. It is often called effective demand, though at other times this term is distinguished. This is the demand for the gross domestic product of a country. It specifies the amount of goods and services that will be purchased at all possible price levels. Consumer spending, investment, corporate and government expenditure, and net exports make up the aggregate demand.
In economics, nominalvalue refers to value measured in terms of absolute money amounts, whereas real value is considered and measured against the actual goods or services for which it can be exchanged at a given time. Real value takes into account inflation and the value of an asset in relation to its purchasing power.
National accounts or national account systems (NAS) are the implementation of complete and consistent accounting techniques for measuring the economic activity of a nation. These include detailed underlying measures that rely on double-entry accounting. By design, such accounting makes the totals on both sides of an account equal even though they each measure different characteristics, for example production and the income from it. As a method, the subject is termed national accounting or, more generally, social accounting. Stated otherwise, national accounts as systems may be distinguished from the economic data associated with those systems. While sharing many common principles with business accounting, national accounts are based on economic concepts. One conceptual construct for representing flows of all economic transactions that take place in an economy is a social accounting matrix with accounts in each respective row-column entry.
The GDP gap or the output gap is the difference between actual GDP or actual output and potential GDP, in an attempt to identify the current economic position over the business cycle. The measure of output gap is largely used in macroeconomic policy. The GDP gap is a highly criticized notion, in particular due to the fact that the potential GDP is not an observable variable, it is instead often derived from past GDP data, which could lead to systemic downward biases.
Gross regional domestic product (GRDP), gross domestic product of region (GDPR), or gross state product (GSP) is a statistic that measures the size of a region's economy. It is the aggregate of gross value added (GVA) of all resident producer units in the region, and analogous to national gross domestic product. The GRDP includes regional estimates on the three major sectors including their sub-sectors, namely:
Constant purchasing power accounting (CPPA) is an accounting model that is an alternative to model historical cost accounting under high inflation and hyper-inflationary environments. It has been approved for use by the International Accounting Standards Board (IASB) and the US Financial Accounting Standards Board (FASB). Under this IFRS and US GAAP authorized system, financial capital maintenance is always measured in units of constant purchasing power (CPP) in terms of a Daily CPI during low inflation, high inflation, hyperinflation and deflation; i.e., during all possible economic environments. During all economic environments it can also be measured in a monetized daily indexed unit of account or in terms of a daily relatively stable foreign currency parallel rate, particularly during hyperinflation when a government refuses to publish CPI data.
The Lost Decades are a lengthy period of economic stagnation in Japan precipitated by the asset price bubble's collapse beginning in 1990. The singular term Lost Decade originally referred to the 1990s, but the 2000s and the 2010s have been included by commentators as the phenomenon continued.
In statistics, a deflator is a value that allows data to be measured over time in terms of some base period, usually through a price index, in order to distinguish between changes in the money value of a gross national product (GNP) that come from a change in prices, and changes from a change in physical output. It is the measure of the price level for some quantity. A deflator serves as a price index in which the effects of inflation are nulled. It is the difference between real and nominal GDP.
A chained volume series is a series of economic data from successive years, put in real terms by computing the aggregate value of the measure for each year using the prices of the preceding year, and then 'chain linking' the data together to obtain a time-series of figures from which the effects of price changes have, at least in theory, been removed. In other words, from the raw GDP or GNP data, which reflect changes in both production volume and prices, a series is obtained where the changes between years reflect only changes in production volume.
Abenomics refers to the economic policies implemented by the Government of Japan led by the Liberal Democratic Party (LDP) since the December 2012 general election. They are named after Shinzō Abe (1954–2022), who had been appointed as Prime Minister of Japan on his second term from 2012 to 2020. Abe was the longest-serving prime minister in Japanese history. After Abe resigned in September 2020, his successor, Yoshihide Suga, stated that his premiership would focus on continuing the policies and goals of the Abe administration, including the Abenomics suite of economic policies.
