Rational expectationsRational expectations is a set of modeling assumptions describing how macroeconomic agents form expectations about the future under uncertainty. Under these assumptions, agents are presumed to use all relevant and available information, making their expectations “model‑consistent”—that is, behaving as if they fully understand the structural model governing the macroeconomy.Adaptive expectationsIn economics, adaptive expectations is a hypothesized process by which people form their expectations about what will happen in the future based on what has happened in the past. For example, if people want to create an expectation of the inflation rate in the future, they can refer to past inflation rates to infer some consistencies and could derive a more accurate expectation the more years they consider.
Supply and demandIn microeconomics, supply and demand is an economic model of price determination in a market. It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied such that an economic equilibrium is achieved for price and quantity transacted.
PriceA price in economics is the amount of money that buyers are willing and able to pay for a particular good or service, and that sellers are willing to accept. In some situations, especially when the product is a service rather than a physical good, the price for the service may be called something else such as "rent" or "tuition". Prices are influenced by production costs, supply of the desired product, and demand for the product.
Nicholas KaldorNicholas Kaldor, Baron Kaldor (12 May 1908 – 30 September 1986), born Káldor Miklós, was a Hungarian-born British economist. He developed the "compensation" criteria called Kaldor–Hicks efficiency for welfare comparisons (1939), derived the cobweb model, and argued for certain regularities observable in economic growth, which are called Kaldor's growth laws.Market (economics)In economics, a market is any structure that allows buyers and sellers to exchange goods, services and information. The exchange of goods or services, either with money or without it, is a transaction. In free market economies, they are the process by which prices and allocations of goods and services are established. Markets facilitate trade and enable the distribution and allocation of resources in a society by allowing tradeable items to be evaluated and priced.
Supply (economics)In economics, supply is the amount of a resource that firms, , labourers, providers of financial assets, or other economic agents are willing and able to provide to the marketplace or to an individual. Supply can be in produced goods, labour time, raw materials, or any other scarce or valuable object. Supply is often plotted graphically as a supply curve, with the price per unit on the vertical axis and quantity supplied as a function of price on the horizontal axis.HarvestHarvesting is the process of collecting plants, animals, or fish (as well as fungi) as food, especially the process of gathering mature crops, and "the harvest" also refers to the collected crops. Reaping is the cutting of grain or pulses for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season.
Economic modelAn economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes. Frequently, economic models posit structural parameters. A model may have various exogenous variables, and those variables may change to create various responses by economic variables.
Henry SchultzHenry Schultz (September 4, 1893 – November 26, 1938) was an American economist, statistician, and one of the founders of econometrics. Paul Samuelson named Schultz (along with Harry Gunnison Brown, Allyn Abbott Young, Henry Ludwell Moore, Frank Knight, Jacob Viner, and Wesley Clair Mitchell) as one of the several "American saints in economics" born after 1860.
Expected valueAverage value of a random variableIn probability theory, the expected value (also called expectation, mean, or first moment) is a generalization of the weighted average. Provided that it is finite, the expected value can be interpreted as the long-run average of results from independent repetitions of the same random experiment, as formalized by the law of large numbers.Umberto RicciUmberto Ricci (1879–1946) was an Italian academic and economist who served as the minister of education in 1945 shortly after the end of the Fascist rule in Italy. He was a leading academic and worked at various universities. Early life and educationRicci was born in Chieti on 20 February 1879.
