Marginal propensity to consumeIn economics, the marginal propensity to consume (MPC) is a metric that quantifies induced consumption, the concept that the increase in personal consumer spending (consumption) occurs with an increase in disposable income (income after taxes and transfers). The proportion of disposable income which individuals spend on consumption is known as propensity to consume. MPC is the proportion of additional income that an individual consumes. For example, if a household earns one extra dollar of disposable income, and the marginal propensity to consume is 0.
General glutIn macroeconomics, a general glut is an excess of supply in relation to demand, specifically, when there is more production in all fields of production in comparison with what resources are available to consume (purchase) said production. This exhibits itself in a general recession or depression, with high and persistent underutilization of resources, notably unemployment and idle factories. The Great Depression is often cited as an archetypal example of a general glut.
Velocity of moneyThe velocity of money measures the number of times that the average unit of currency is used to purchase goods and services within a given time period. The concept relates the size of economic activity to a given money supply, and the speed of money exchange is one of the variables that determine inflation. The measure of the velocity of money is usually the ratio of the gross national product (GNP) to a country's money supply. If the velocity of money is increasing, then transactions are occurring between individuals more frequently.
Saltwater and freshwater economicsIn economics, the freshwater school (or sometimes sweetwater school) comprises US-based macroeconomists who, in the early 1970s, challenged the prevailing consensus in macroeconomics research. A key element of their approach was the argument that macroeconomics had to be dynamic and based on how individuals and institutions interact in markets and make decisions under uncertainty.
Stimulus (economics)In economics, stimulus refers to attempts to use monetary policy or fiscal policy (or stabilization policy in general) to stimulate the economy. Stimulus can also refer to monetary policies such as lowering interest rates and quantitative easing. A stimulus is sometimes colloquially referred to as "priming the pump" or "pump priming". During a recession, production and employment are far below their sustainable potential due to lack of demand. It is hoped that increasing demand will stimulate growth and that any adverse side effects from stimulus will be mild.
Potential outputIn economics, potential output (also referred to as "natural gross domestic product") refers to the highest level of real gross domestic product (potential output) that can be sustained over the long term. Actual output happens in real life while potential output shows the level that could be achieved. Natural (physical, etc) and institutional constraints impose limits to growth. If actual GDP rises and stays above potential output, then, in a free market economy (i.e.
ChartalismIn macroeconomics, chartalism is a heterodox theory of money that argues that money originated historically with states' attempts to direct economic activity rather than as a spontaneous solution to the problems with barter or as a means with which to tokenize debt, and that fiat currency has value in exchange because of sovereign power to levy taxes on economic activity payable in the currency they issue. George Friedrich Knapp, a German economist, invented the term "chartalism" in his State Theory of Money, which was published in German in 1905 and translated into English in 1924.
Effective demandIn economics, effective demand (ED) in a market is the demand for a product or service which occurs when purchasers are constrained in a different market. It contrasts with notional demand, which is the demand that occurs when purchasers are not constrained in any other market. In the aggregated market for goods in general, demand, notional or effective, is referred to as aggregate demand. The concept of effective supply parallels the concept of effective demand.
Policy-ineffectiveness propositionThe policy-ineffectiveness proposition (PIP) is a new classical theory proposed in 1975 by Thomas J. Sargent and Neil Wallace based upon the theory of rational expectations, which posits that monetary policy cannot systematically manage the levels of output and employment in the economy. Prior to the work of Sargent and Wallace, macroeconomic models were largely based on the adaptive expectations assumption. Many economists found this unsatisfactory since it assumes that agents may repeatedly make systematic errors and can only revise their expectations in a backward-looking way.
Job guaranteeA job guarantee is an economic policy proposal that aims to provide a sustainable solution to inflation and unemployment. Its aim is to create full employment and price stability by having the state promise to hire unemployed workers as an employer of last resort (ELR). The economic policy stance currently dominant around the world uses unemployment as a policy tool to control inflation. When inflation rises, the government pursues contractionary fiscal or monetary policy, with the aim of creating a buffer stock of unemployed people, reducing wage demands, and ultimately inflation.
