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.
Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, 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.
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.
In economics, inflation is a general increase in the prices of goods and services in an economy. This is usually measured using a 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.
A pension is a fund into which amounts are paid regularly during an individual's working career, and from which periodic payments are made to support the person's retirement from work. A pension may be:
An informal economy is the part of any economy that is neither taxed nor monitored by any form of government. Although the informal sector makes up a significant portion of the economies in developing countries, it is sometimes stigmatized as troublesome and unmanageable. However, the informal sector provides critical economic opportunities for the poor and has been expanding rapidly since the 1960s. Integrating the informal economy into the formal sector is an important policy challenge.
Economic growth can be defined as the increase or improvement in the inflation-adjusted economy in a financial year. The economic growth rate is typically calculated as real Gross domestic product (GDP) growth rate, real GDP per capita growth rate or GNI per capita growth. The "rate" of economic growth refers to the geometric annual rate of growth in GDP or GDP per capita between the first and the last year over a period of time. This growth rate represents the trend in the average level of GDP over the period, and ignores any fluctuations in the GDP around this trend. Growth is usually calculated in "real" value, which is inflation-adjusted, to eliminate the distorting effect of inflation on the prices of goods produced. Real GDP per capita is the GDP of the entire country divided by the number of people in the country. Measurement of economic growth uses national income accounting.
In economics and political science, fiscal policy is the use of government revenue collection and expenditure to influence a country's economy. The use of government revenue expenditures to influence macroeconomic variables developed in reaction to the Great Depression of the 1930s, when the previous laissez-faire approach to economic management became unworkable. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorised that government changes in the levels of taxation and government spending influence aggregate demand and the level of economic activity. Fiscal and monetary policy are the key strategies used by a country's government and central bank to advance its economic objectives. The combination of these policies enables these authorities to target inflation and to increase employment. In modern economies, inflation is conventionally considered "healthy" in the range of 2%–3%. Additionally, it is designed to try to keep GDP growth at 2%–3% and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilise the economy over the course of the business cycle.
The Phillips curve is an economic model, named after Bill Phillips, that correlates reduced unemployment with increasing wages in an economy. While Phillips did not directly link employment and inflation, this was a trivial deduction from his statistical findings. Paul Samuelson and Robert Solow made the connection explicit and subsequently Milton Friedman and Edmund Phelps put the theoretical structure in place.
Business cycles are intervals of general expansion followed by recession in economic performance. The changes in economic activity that characterize business cycles have important implications for the welfare of the general population, government institutions, and private sector firms.
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.
In economics, Okun's law is an empirically observed relationship between unemployment and losses in a country's production. It is named after Arthur Melvin Okun, who first proposed the relationship in 1962. The "gap version" states that for every 1% increase in the unemployment rate, a country's GDP will be roughly an additional 2% lower than its potential GDP. The "difference version" describes the relationship between quarterly changes in unemployment and quarterly changes in real GDP. The stability and usefulness of the law has been disputed.
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.
Poverty is measured in different ways by different bodies, both governmental and nongovernmental. Measurements can be absolute, which references a single standard, or relative, which is dependent on context. Poverty is widely understood to be multidimensional, comprising social, natural and economic factors situated within wider socio-political processes.
New classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical framework. Specifically, it emphasizes the importance of rigorous foundations based on microeconomics, especially rational expectations.
The non-accelerating inflation rate of unemployment (NAIRU) is a theoretical level of unemployment below which inflation would be expected to rise. It was first introduced as the NIRU by Franco Modigliani and Lucas Papademos in 1975, as an improvement over the "natural rate of unemployment" concept, which was proposed earlier by Milton Friedman.
A maximum wage, also often called a wage ceiling, is a legal limit on how much income an individual can earn. It is a prescribed limitation which can be used to effect change in an economic structure.
China's current mainly market economy features a high degree of income inequality. According to the Asian Development Bank Institute, "before China implemented reform and opening-up policies in 1978, its income distribution pattern was characterized as egalitarian in all aspects."
Deficit reduction in the United States refers to taxation, spending, and economic policy debates and proposals designed to reduce the federal government budget deficit. Government agencies including the Government Accountability Office (GAO), Congressional Budget Office (CBO), the Office of Management and Budget (OMB), and the U.S. Treasury Department have reported that the federal government is facing a series of important long-run financing challenges, mainly driven by an aging population, rising healthcare costs per person, and rising interest payments on the national debt.
The gender pay gap or gender wage gap is the average difference between the remuneration for men and women who are employed. Women are generally found to be paid less than men. There are two distinct measurements of the pay gap: non-adjusted versus adjusted pay gap. The latter typically takes into account differences in hours worked, occupations chosen, education and job experience. In other words, the adjusted values represent how much women and men make for the same work, while the non-adjusted values represent how much the average man and woman make in total. In the United States, for example, the non-adjusted average woman's annual salary is 79–83% of the average man's salary, compared to 95–99% for the adjusted average salary. The reasons for the gap link to legal, social and economic factors. These include having children, parental leave, gender discrimination and gender norms. Additionally, the consequences of the gender pay gap surpass individual grievances, leading to reduced economic output, lower pensions for women, and fewer learning opportunities.
