Shortage
In economics, a shortage or excess demand is a situation in which the demand for a product or service exceeds its supply in a market. It is the opposite of an excess supply ( surplus). Definitions In a perfect market (one that matches a simple microeconomic model), an excess of demand will prompt sellers to increase prices until demand at that price matches the available supply, establishing market equilibrium. In economic terminology, a shortage occurs when for some reason (such as government intervention, or decisions by sellers not to raise prices) the price does not rise to reach equilibrium. In this circumstance, buyers want to purchase more at the market price than the quantity of the good or service that is available, and some non-price mechanism (such as "first come, first served" or a lottery) determines which buyers are served. So in a perfect market the only thing that can cause a shortage is price. In common use, the term "shortage" may refer to a situation wh ...

Price Control
Price controls are restrictions set in place and enforced by governments, on the prices that can be charged for goods and services in a market. The intent behind implementing such controls can stem from the desire to maintain affordability of goods even during shortages, and to slow inflation, or, alternatively, to ensure a minimum income for providers of certain goods or to try to achieve a living wage. There are two primary forms of price control: a price ceiling, the maximum price that can be charged; and a price floor, the minimum price that can be charged. A well-known example of a price ceiling is rent control, which limits the increases that a landlord is permitted by government to charge for rent. A widely used price floor is minimum wage (wages are the price of labor). Historically, price controls have often been imposed as part of a larger incomes policy package also employing wage controls and other regulatory elements. Although price controls are routinely used by gover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Equilibrium
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 ( equilibrium) 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. Market equilibrium in this case is a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers. This price is often called the competitive price or market clearing price and will tend not to change unless demand or supply changes, and quantity is called the "competitive quantity" or market clearing quantity. But the concept of ''equilibrium'' in economics also applies to imperfectly competitive markets, where it takes the form of a Nash equilibrium. Understanding economic equili ...

Price Ceiling
A price ceiling is a government- or group-imposed price control, or limit, on how high a price is charged for a product, commodity, or service. Governments use price ceilings ostensibly to protect consumers from conditions that could make commodities prohibitively expensive. Such conditions can occur during periods of high inflation, in the event of an investment bubble, or in the event of monopoly ownership of a product, all of which can cause problems if imposed for a long period without controlled rationing, leading to shortages. Further problems can occur if a government sets unrealistic price ceilings, causing business failures, stock crashes, or even economic crises. In unregulated market economies, price ceilings do not exist. While price ceilings are often imposed by governments, there are also price ceilings that are implemented by non-governmental organizations such as companies, such as the practice of resale price maintenance. With resale price maintenance, a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Market Clearing
In economics, market clearing is the process by which, in an economic market, the supply of whatever is traded is equated to the demand so that there is no excess supply or demand. The new classical economics assumes that in any given market, assuming that all buyers and sellers have access to information and that there is no "friction" impeding price changes, prices ''always'' adjust up or down to ensure market clearing. Mechanism and examples A market-clearing price is the price of a good or service at which quantity supplied is equal to quantity demanded, also called the equilibrium price. The theory claims that markets tend to move toward this price. For a one-time sale of goods, supply is fixed, so the market-clearing price is simply the maximum price at which all items can be sold. For a market where goods are produced and sold on an ongoing basis, the theory predicts that the market will move toward a price where the quantity supplied in a broad time period will equal the ...

Excess Supply
In economics, an excess supply, economic surplus market surplus or briefly surply is a situation in which the quantity of a good or service supplied is more than the quantity demanded, and the price is above the equilibrium level determined by supply and demand. That is, the quantity of the product that producers wish to sell exceeds the quantity that potential buyers are willing to buy at the prevailing price. It is the opposite of an economic shortage ( excess demand). In cultural evolution, agricultural surplus in the Neolithic period is theorized to have produced a greater division of labor, resulting in social stratification and class. Prices Prices and the occurrence of excess supply illustrate a strong correlation. When the price of a good is set too high, the quantity of the product demanded will be diminished while the quantity supplied will be enhanced, so there is more quantity supplied than quantity demanded. The occurrence of excess supply either leads to the lower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Price Gouging
Price gouging is a pejorative term used to describe the situation when a seller increases the prices of goods, services, or commodities to a level much higher than is considered reasonable or fair. Usually, this event occurs after a demand or supply shock. This term is commonly used to describe price increases of basic necessities after natural disasters. In legal usage, price gouging is the name of a crime that applies in some jurisdictions of the United States during civil emergencies. In less precise usage, the term can also be used to refer to profits obtained by practices inconsistent with a competitive free market, or to windfall profits. Price gouging is considered by some to be exploitative and unethical. The term is similar to profiteering but can be distinguished by being short-term and localized and by being restricted to essentials such as food, clothing, shelter, medicine, and equipment needed to preserve life and property. In jurisdictions where there is no su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microeconomic
Microeconomics is a branch of mainstream economics that studies the behavior of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms. Microeconomics focuses on the study of individual markets, sectors, or industries as opposed to the national economy as whole, which is studied in macroeconomics. One goal of microeconomics is to analyze the market mechanisms that establish relative prices among goods and services and allocate limited resources among alternative uses. Microeconomics shows conditions under which free markets lead to desirable allocations. It also analyzes market failure, where markets fail to produce efficient results. While microeconomics focuses on firms and individuals, macroeconomics focuses on the sum total of economic activity, dealing with the issues of growth, inflation, and unemployment and with national policies relating to these issues. Microeconomics also d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unemployed Men Queued Outside A Depression Soup Kitchen Opened In Chicago By Al Capone, 02-1931 - NARA - 541927
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is people above a specified age (usually 15) not being in paid employment or self-employment but currently available for work during the reference period. Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed). Unemployment can have many sources, such as the following: * new technologies and inventions * the status of the economy, which can be influenced by a recession * competition caused by globalization and international trade * policies of the government * regulation and market Unemployment and the status of the economy can be influenced by a country through, for example, fiscal policy. Furthermore, the monetary authority of a country, such as the central bank, can influence the availability and cost for money through its moneta ...

Economics
Economics () is the social science that studies the production, distribution, and consumption of goods and services. Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyzes what's viewed as basic elements in the economy, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyzes the economy as a system where production, consumption, saving, and investment interact, and factors affecting it: employment of the resources of labour, capital, and land, currency inflation, economic growth, and public policies that have impact on these elements. Other broad distinctions within economics include those between positive economics, describing "what is", and normative economics, advocating "what ought to be"; between economic theory and applied economics; between rational a ...

Elderly Care
Elderly care, or simply eldercare (also known in parts of the English-speaking world as aged care), serves the needs and requirements of senior citizens. It encompasses assisted living, adult daycare, long-term care, nursing homes (often called residential care), hospice care, and home care. Elderly care emphasizes the social and personal requirements of senior citizens who wish to age with dignity while needing assistance with daily activities and with healthcare. Much elderly care is unpaid. Elderly care includes a broad range of practices and institutions, as there is a wide variety of elderly care needs and cultural perspectives on the elderly throughout the world. Cultural and geographic differences The form of care provided for older adults varies greatly by country and even region, and is changing rapidly. Older people worldwide consume the most health spending of any age group. There is also an increasingly large proportion of older people worldwide, especially i ...

Recreational Drug Use
Recreational drug use indicates the use of one or more psychoactive drugs to induce an altered state of consciousness either for pleasure or for some other casual purpose or pastime by modifying the perceptions and emotions of the user. When a psychoactive drug enters the user's body, it induces an intoxicating effect. Generally, recreational drugs are divided into three categories: depressants (drugs that induce a feeling of relaxation and calmness); stimulants (drugs that induce a sense of energy and alertness); and hallucinogens (drugs that induce perceptual distortions such as hallucination). In popular practice, recreational drug use generally is a tolerated social behaviour, rather than perceived as the medical condition of self-medication. However, heavy use of some drugs is socially stigmatized. Many people also use prescribed and controlled depressants such as opioids, as well as opiates and benzodiazepines. Common recreational drugs include caffeine, commonly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food Industry
The food industry is a complex, global network of diverse businesses that supplies most of the food consumed by the world's population. The food industry today has become highly diversified, with manufacturing ranging from small, traditional, family-run activities that are highly labor-intensive, to large, capital-intensive and highly mechanized industrial processes. Many food industries depend almost entirely on local agriculture, produce, or fishing. It is challenging to find an inclusive way to cover all aspects of food production and sale. The UK Food Standards Agency describes it as "the whole food industry – from farming and food production, packaging and distribution, to retail and catering." The Economic Research Service of the USDA uses the term ''food system'' to describe the same thing, stating: "The U.S. food system is a complex network of farmers and the industries that link to them. Those links include makers of farm equipment and chemicals as well as firms tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
