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.<ref>Tucker (2014) Economics Today</ref><ref>{{Cite journal |date=2016-06-17 |title=3.3 Demand, Supply, and Equilibrium |url=https://open.lib.umn.edu/principleseconomics/chapter/3-3-demand-supply-and-equilibrium/ |journal=Principles of Economics |language=en-us |publisher=University of Minnesota}}</ref> 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 where most people are unable to find a desired good at an affordable price, especially where supply problems have increased the price.<ref name=":1">{{Cite web |last=Pettinger |first=Tejvan |title=Shortages |url=https://www.economicshelp.org/blog/146202/economics/shortages/ |access-date=2022-10-06 |website=Economics Help |date=3 April 2020 |language=en-GB}}</ref> "Market clearing" happens when all buyers and sellers willing to transact at the prevailing price are able to find partners. There are almost always willing buyers at a lower-than-market-clearing price; the narrower technical definition doesn't consider failure to serve this demand as a "shortage", even if it would be described that way in a social or political context (which the simple model of supply and demand does not attempt to encompass).

== Causes == Shortages (in the technical sense) may be caused by the following causes:

* Price ceilings, a type of price control which involves a government-imposed limit on the price of a product or service. * Anti-price gouging laws. * Government ban on the sale of a product or service, such as prostitution or certain recreational drugs. * Branding efforts, i.e. a supplier selling a product below the market-clearing price, in order to cause a visible shortage so as to plant an impression of desirability in the minds of consumers. This is typically employed in the marketing of high status goods and services. * Decisions by suppliers not to raise prices in order to maintain friendly relationships with potential future customers during a supply disruption. * Artificial scarcity.

== Effects == Decisions which result in a below-market-clearing price help some people and hurt others. In this case, shortages may be accepted because they theoretically enable a certain portion of the population to purchase a product that they couldn't afford at the market-clearing price. The cost is to those who are willing to pay for a product and either can't, or experience greater difficulty in doing so.

In the case of government intervention in the market, there is always a trade-off with positive and negative effects. For example, a price ceiling may cause a shortage, but it will also enable a certain percentage of the population to purchase a product that they couldn't afford at market costs.<ref name=":1" /> Economic shortages caused by higher transaction costs and opportunity costs (e.g., in the form of lost time) also mean that the distribution process is wasteful. Both of these factors contribute to a decrease in aggregate wealth.

Shortages may or will cause:<ref name=":1" />

* Black (illegal) and Grey (unregulated) markets in which products that are unavailable in conventional markets are sold, or in which products with excess demand are sold at higher prices than in the conventional market. * Artificial controls of demand, such as time (such as waiting in line at queues) and rationing. * Non-monetary bargaining methods, such as time (for example queuing), nepotism, or even violence. * Panic buying * Price discrimination. * The inability to purchase a product, and subsequent forced saving. * Increase in demand for substitute goods. * Deadweight loss due to artificial scarcity; a net loss of economic welfare to society occurs when an artificial limit of supply (by monopolies or oligopolies to maximise profits), limits the number of people who can enjoy the good.

==Labour shortage== {{Further|Labour economics|Exploitation of labour|Wage slavery}}

In its narrowest definition, a labour shortage is an economic condition in which employers believe there are insufficient qualified candidates (employees) to fill the marketplace demands for employment at a specific wage. Such a condition is sometimes referred to by economists as "an insufficiency in the labour force."{{Citation needed|date=July 2025}} According to the Frisch elasticity of labor supply, lower wages reduce labour supply.<ref name="b013">{{cite journal | last=Keane | first=Michael P. | title=Recent research on labor supply: Implications for tax and transfer policy | journal=Labour Economics | volume=77 | date=2022 | doi=10.1016/j.labeco.2021.102026 | doi-access=free | article-number=102026 | url=https://unsworks.unsw.edu.au/bitstreams/960dcb86-30f8-478f-b8a7-1a3215f0cdc7/download | access-date=25 July 2025| hdl=1959.4/unsworks_80539 | hdl-access=free }}</ref>

In a wider definition, a widespread and persistent domestic labour shortage is caused by excessively low salaries (relative to the domestic cost of living) and adverse working conditions (excessive workload and working hours) in low-wage industries (hospitality and leisure, education, health care, rail transportation, aviation, retail, manufacturing, food, elderly care), which collectively lead to occupational burnout and attrition of existing workers, reduced incentives to attract domestic workers, short-staffing at workplaces and further exacerbation (positive feedback) of staff shortages.<ref name=":0">{{Cite news |last=Bhattarai |first=Abha |date=2022-09-16 |title=Worker shortages are fueling America's biggest labor crises |url=https://www.washingtonpost.com/business/2022/09/16/worker-shortage-strikes-economy/ |access-date=2022-10-06 |newspaper=The Washington Post |language=en}}</ref>

Labour shortages can occur even during economic periods of high unemployment or youth unemployment within specific industries due to low salaries offered.<ref>{{Cite web |last=West |first=Darrell M. |date=April 10, 2013 |title=The Paradox of Worker Shortages at a Time of High National Unemployment |url=https://www.brookings.edu/research/the-paradox-of-worker-shortages-at-a-time-of-high-national-unemployment/ |access-date=2022-10-06 |website=Brookings Institution |language=en-US}}</ref> In response to domestic labour shortages, some business associations such as chambers of commerce, trade associations or employers' organizations lobby for an increased immigration of foreign workers which accept lower salaries according to the global labor arbitrage.<ref>{{Cite web |title=U.S. Chamber's Bradley: The Current Labor Shortage is 'Unprecedented,' Urges Solutions on Immigration, Childcare |url=https://www.uschamber.com/workforce/u-s-chambers-bradley-the-current-labor-shortage-is-unprecedented-urges-solutions-on-immigration-childcare |access-date=2022-10-06 |website=United States Chamber of Commerce |date=6 May 2022 |language=en}}</ref> In addition, business associations have campaigned for greater state provision of child care, which would enable more women to re-enter the labour workforce at a lower wage rate to achieve economic equilibrium.<ref>{{Cite web |title=Data Deep Dive: A Decline of Women in the Workforce |url=https://www.uschamber.com/workforce/data-deep-dive-a-decline-of-women-in-the-workforce |access-date=2022-10-06 |website=United States Chamber of Commerce |date=27 April 2022 |language=en}}</ref> However, lower salaries discourage local labour from entering the relevant industries and can cause labour shortages in developing countries.<ref>{{Cite web |last=Daniel |first=Dana |date=2022-07-29 |title=Train your own nurses, Australia told amid global shortage |url=https://www.smh.com.au/politics/federal/train-your-own-nurses-australia-told-amid-global-shortage-20220725-p5b4b2.html |access-date=2022-10-06 |website=The Sydney Morning Herald |language=en}}</ref>

The Atlantic slave trade (which originated in the early 17th century but ended by the early 19th century) was said to have originated from perceived shortages of agricultural labour in the Americas (particularly in the Southern United States). It was thought that bringing African labor was the only means of malaria resistance available at the time.<ref>[http://www.malaria.com/blog/american-plasmodium-vivax "As American as…Plasmodium vivax?"]</ref>
