Screening (economics)
Screening in economics refers to a strategy of combating adverse selection In economics, insurance, and risk management, adverse selection is a market situation where Information asymmetry, asymmetric information results in a party taking advantage of undisclosed information to benefit more from a contract or trade. In ... – one of the potential decision-making complications in cases of asymmetric information – by the agent(s) with less information. For the purposes of screening, asymmetric information cases assume two economic agents, with agents attempting to engage in some sort of transaction. There often exists a long-term relationship between the two agents, though that qualifier is not necessary. Fundamentally, the Strategy (game theory), strategy involved with screening comprises the “screener” (the agent with less information) attempting to gain further insight or knowledge into private information that the other economic agent possesses which is initially unk ...

Economics
Economics () is a behavioral science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services. Economics focuses on the behaviour and interactions of Agent (economics), economic agents and how economy, economies work. Microeconomics analyses what is viewed as basic elements within economy, economies, including individual agents and market (economics), markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and Expenditure, investment expenditure interact; and the factors of production affecting them, such as: Labour (human activity), labour, Capital (economics), capital, Land (economics), land, and Entrepreneurship, enterprise, inflation, economic growth, and public policies that impact gloss ...

Background Check
A background check is a process used by an organisation or person to verify that an individual is who they claim to be, and check their past record to confirm education, employment history, and other activities, and for a criminal record. The frequency, purpose, and legitimacy of background checks vary among countries, industries, and individuals. An employment background check typically takes place when someone applies for a job, but it can also happen at any time the employer deems necessary. A variety of methods are used to complete these checks, including comprehensive database search and letters of reference. History In the United States Pre September 11 2001, background checks were less common and less intrusive. In the 2000s, background checks became far more common after 9/11. Organizations such as the Transportation Security Administration (TSA) were created afterwards to protect national security and safeguard American citizens. These agencies were tasked with ex ...

Mathematics Of Operations Research
''Mathematics of Operations Research'' is a quarterly peer-reviewed scientific journal established in February 1976. It focuses on areas of mathematics relevant to the field of operations research such as continuous optimization, discrete optimization, game theory, machine learning, simulation methodology, and stochastic models. The journal is published by INFORMS (Institute for Operations Research and the Management Sciences). the journal has a 2017 impact factor of 1.078. History The journal was established in 1976. The founding editor-in-chief was Arthur F. Veinott Jr. (Stanford University). He served until 1980, when the position was taken over by Stephen M. Robinson, who held the position until 1986. Erhan Cinlar served from 1987 to 1992, and was followed by Jan Karel Lenstra (1993-1998). Next was Gérard Cornuéjols (1999-2003) and Nimrod Megiddo (2004-2009). Finally came Uri Rothblum (2009-2012), Jim Dai (2012-2018), and the current editor-in-chief Katya Scheinberg (20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contract Theory
From a legal point of view, a contract is an institutional arrangement for the way in which resources flow, which defines the various relationships between the parties to a transaction or limits the rights and obligations of the parties. From an economic perspective, contract theory studies how economic actors can and do construct contractual arrangements, generally in the presence of information asymmetry. Because of its connections with both agency and incentive In general, incentives are anything that persuade a person or organization to alter their behavior to produce the desired outcome. The laws of economists and of behavior state that higher incentives amount to greater levels of effort and therefo ...s, contract theory is often categorized within a field known as law and economics. One prominent application of it is the design of optimal schemes of managerial compensation. In the field of economics, the first formal treatment of this topic was given by Kenneth Arrow ...

Inefficiency
Efficiency is the often measurable ability to avoid making mistakes or wasting materials, energy, efforts, money, and time while performing a task. In a more general sense, it is the ability to do things well, successfully, and without waste. In more mathematical or scientific terms, it signifies the level of performance that uses the least amount of inputs to achieve the highest amount of output. It often specifically comprises the capability of a specific application of effort to produce a specific outcome with a minimum amount or quantity of waste, expense, or unnecessary effort.Sickles, R., and Zelenyuk, V. (2019).Measurement of Productivity and Efficiency: Theory and Practice. Cambridge: Cambridge University Press. . Efficiency refers to very different inputs and outputs in different fields and industries. In 2019, the European Commission said: "Resource efficiency means using the Earth's limited resources in a sustainable procent manner while minimising impacts on the envi ...

Economic Surplus
In mainstream economics, economic surplus, also known as total welfare or total social welfare or Marshallian surplus (after Alfred Marshall), is either of two related quantities: * Consumer surplus, or consumers' surplus, is the monetary gain obtained by consumers because they are able to purchase a product for a price that is less than the highest price that they would be willing to pay. * Producer surplus, or producers' surplus, is the amount that producers benefit by selling at a market price that is higher than the least that they would be willing to sell for; this is roughly equal to profit (since producers are not normally willing to sell at a loss and are normally indifferent to selling at a break-even price). The sum of consumer and producer surplus is sometimes known as social surplus or total surplus; a decrease in that total from inefficiencies is called deadweight loss.

Willingness To Pay
In behavioral economics, willingness to pay (WTP) is the maximum price at or below which a consumer will definitely buy one unit of a product. This corresponds to the standard economic view of a consumer reservation price. Some researchers, however, conceptualize WTP as a range. According to the constructed preference view, consumer willingness to pay is a context-sensitive construct; that is, a consumer's WTP for a product depends on the concrete decision context. For example, consumers tend to be willing to pay more for a soft drink in a luxury hotel resort in comparison to a beach bar or a local retail store. Experimental context In laboratory experiments auctions are conducted, a premise of the experiment is often that "bid = WTP". See also * Cost-benefit analysis * Welfare economics Welfare economics is a field of economics that applies microeconomic techniques to evaluate the overall well-being (welfare) of a society. The principles of welfare economics are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Price Discrimination
Price discrimination (differential pricing, equity pricing, preferential pricing, dual pricing, tiered pricing, and surveillance pricing) is a Microeconomics, microeconomic Pricing strategies, pricing strategy where identical or largely similar goods or services are sold at different Price, prices by the same provider to different buyers based on which Market segmentation, market segment they are perceived to be part of. Price discrimination is distinguished from product differentiation by the difference in production cost for the differently priced products involved in the latter strategy. Price discrimination essentially relies on the variation in customers' willingness to pay and in the Demand elasticity, elasticity of their demand. For price discrimination to succeed, a seller must have market power, such as a dominant market share, product uniqueness, sole pricing power, etc. Some prices under price discrimination may be lower than the price charged by a single-price monopoli ...

Product Launch
New product development (NPD) or product development in business and engineering covers the complete process of launching a new product to the market. Product development also includes the renewal of an existing product and introducing a product into a new market. A central aspect of NPD is product design. New product development is the realization of a market opportunity by making a product available for purchase. The products developed by an commercial organisation provide the means to generate income. Many technology-intensive organisations exploit technological innovation in a rapidly changing consumer market. A product can be a tangible asset or intangible. A service or user experience is intangible. In law, sometimes services and other processes are distinguished from "products". NPD requires an understanding of customer needs and wants, the competitive environment, and the nature of the market. Cost, time, and quality are the main variables that drive customer needs. Ai ...

Test Market
A test market, in the field of business and marketing, is a geographic region or demographic group used to gauge the viability of a product or service in the mass market prior to a wide scale rollout. The criteria used to judge the acceptability of a test market region or group include: #a population that is demographically similar to the proposed target market; and #relative isolation from densely populated media markets so that advertising to the test audience can be efficient and economical. Practical use The test market ideally aims to duplicate "everything" - promotion and distribution as well as "product" - on a smaller scale. The technique replicates, typically in one area, what is planned to occur in a national launch; and the results are very carefully monitored, so that they can be extrapolated to projected national results. The area may be any one of the following: *Television area *Internet online test *Test town *Residential neighborhood *Test site A number of dec ...

Research And Development
Research and development (R&D or R+D), known in some countries as OKB, experiment and design, is the set of innovative activities undertaken by corporations or governments in developing new services or products. R&D constitutes the first stage of development of a potential new service or the production process. Although R&D activities may differ across businesses, the primary goal of an R&D department is to new product development, develop new products and services. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. R&D is crucial for acquiring larger shares of the market through new products. ''R&D&I'' represents R&D with innovation. Background New product design and development is often a crucial factor in the survival of a company. In a global industrial landscape that is changing fast, firms must continually revise their design and range of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moral Hazard
In economics, a moral hazard is a situation where an economic actor has an incentive to increase its exposure to risk because it does not bear the full costs associated with that risk, should things go wrong. For example, when a corporation is insured, it may take on higher risk knowing that its insurance will pay the associated costs. A moral hazard may occur where the actions of the risk-taking party change to the detriment of the cost-bearing party after a financial transaction has taken place. Moral hazard can occur under a type of information asymmetry where the risk-taking party to a transaction knows more about its intentions than the party paying the consequences of the risk and has a tendency or incentive to take on too much risk from the perspective of the party with less information. One example is a principal–agent approach (also called agency theory), where one party, called an agent, acts on behalf of another party, called the principal. However, a principa ...
