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.
In economics, stagflation is a situation in which the inflation rate is high or increasing, the economic growth rate slows, and unemployment remains steadily high. Stagflation, once thought impossible, poses a dilemma for economic policy, as measures to reduce inflation may exacerbate unemployment.
Unemployment, according to the OECD, is people above a specified age not being in paid employment or self-employment but currently available for work during the reference period.
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.
Full employment is an economic situation in which there is no cyclical or deficient-demand unemployment. Full employment does not entail the disappearance of all unemployment, as other kinds of unemployment, namely structural and frictional, may remain. For instance, workers who are "between jobs" for short periods of time as they search for better employment are not counted against full employment, as such unemployment is frictional rather than cyclical. An economy with full employment might also have unemployment or underemployment where part-time workers cannot find jobs appropriate to their skill level, as such unemployment is considered structural rather than cyclical. Full employment marks the point past which expansionary fiscal and/or monetary policy cannot reduce unemployment any further without causing inflation.
New Keynesian economics is a school of macroeconomics that strives to provide microeconomic foundations for Keynesian economics. It developed partly as a response to criticisms of Keynesian macroeconomics by adherents of new classical macroeconomics.
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.
In economics, economic equilibrium is a situation in which economic forces such as supply and demand are balanced and in the absence of external influences the values of economic variables will not change. For example, in the standard text perfect competition, equilibrium occurs at the point at which quantity demanded and quantity supplied are equal.
Underemployment is the underuse of a worker because their job does not use their skills, offers them too few hours, or leaves the worker idle. It is contrasted with unemployment, where a person lacks a job at all despite wanting one.
The economies of Canada and the United States are similar because both are developed countries. While both countries feature in the top ten economies in the world in 2022, the U.S. is the largest economy in the world, with US$24.8 trillion, with Canada ranking ninth at US$2.2 trillion.
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.
In economics, the Baumol effect, also known as Baumol's cost disease, first described by William J. Baumol and William G. Bowen in the 1960s, is the tendency for wages in jobs that have experienced little or no increase in labor productivity to rise in response to rising wages in other jobs that did experience high productivity growth. In turn, these sectors of the economy become more expensive over time, because their input costs have increased while productivity has not. Typically, this affects services more than manufactured goods, and in particular health, education, arts and culture.
Economic stagnation is a prolonged period of slow economic growth, usually accompanied by high unemployment. Under some definitions, slow means significantly slower than potential growth as estimated by macroeconomists, even though the growth rate may be nominally higher than in other countries not experiencing economic stagnation.
In economics, personal income refers to the total earnings of an individual from various sources such as wages, investment ventures, and other sources of income. It encompasses all the products and money received by an individual.
The neoclassical synthesis (NCS), or neoclassical–Keynesian synthesis is an academic movement and paradigm in economics that worked towards reconciling the macroeconomic thought of John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) with neoclassical economics.
The middle-class squeeze refers to negative trends in the standard of living and other conditions of the middle class of the population. Increases in wages fail to keep up with inflation for middle-income earners, leading to a relative decline in real wages, while at the same time, the phenomenon fails to have a similar effect on the top wage earners. People belonging to the middle class find that inflation in consumer goods and the housing market prevent them from maintaining a middle-class lifestyle, undermining aspirations of upward mobility.
Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.
The Fei–Ranis model of economic growth is a dualism model in developmental economics or welfare economics that has been developed by John C. H. Fei and Gustav Ranis and can be understood as an extension of the Lewis model. It is also known as the Surplus Labor model. It recognizes the presence of a dual economy comprising both the modern and the primitive sector and takes the economic situation of unemployment and underemployment of resources into account, unlike many other growth models that consider underdeveloped countries to be homogenous in nature. According to this theory, the primitive sector consists of the existing agricultural sector in the economy, and the modern sector is the rapidly emerging but small industrial sector. Both the sectors co-exist in the economy, wherein lies the crux of the development problem. Development can be brought about only by a complete shift in the focal point of progress from the agricultural to the industrial economy, such that there is augmentation of industrial output. This is done by transfer of labor from the agricultural sector to the industrial one, showing that underdeveloped countries do not suffer from constraints of labor supply. At the same time, growth in the agricultural sector must not be negligible and its output should be sufficient to support the whole economy with food and raw materials. Like in the Harrod–Domar model, saving and investment become the driving forces when it comes to economic development of underdeveloped countries.
Wage growth is a rise of wage adjusted for inflations, often expressed in percentage. In macroeconomics, wage growth is one of the main indications to measure economic growth for a long-term since it reflects the consumer's purchasing power in the economy as well as the level of living standards. An increase in wage growth implies price inflation in the economy while a low wage growth indicates deflation that needs artificial interferences such as through fiscal policies by federal/state government. Minimum wage law is often introduced to increase wage growth by stimulating Price Inflations from corresponding purchasing powers in the economy. Wage growth can also be maximised through the development of industry factors by investing skilled workers in which decision made by businesses. More financial compensation for skilled workers not only lifts wage growth but stimulates higher market prices in the economy.
The decoupling of wages from productivity, sometimes known as the great decoupling, is the gap between the growth rate of median wages and the growth rate of GDP. Economists began to acknowledge this problem toward the end of the twentieth century and the beginning of the twenty-first century. This problem furthermore leads to wage stagnation despite continued economic growth.
