Threshold population

Last updated

In microeconomics, a threshold population is the minimum number of people needed for a service to be worthwhile.

Microeconomics is a branch of economics that studies the behaviour of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms.

Service (economics) intangible offering inseparable from its creators labor, which brings utility value to their buyer

In economics, a service is a transaction in which no physical goods are transferred from the seller to the buyer. The benefits of such a service are held to be demonstrated by the buyer's willingness to make the exchange. Public services are those that society as a whole pays for. Using resources, skill, ingenuity, and experience, service providers benefit service consumers. Service is intangible in nature.

In geography, a threshold population is the minimum number of people necessary before a particular good or service can be provided in an area. The concept is equivalent to the "range" in central place theory and retailing, which delineates the market area of a central place for a particular good or service, and is dependent on the spatial distribution of population and the willingness of consumers to travel a given distance to purchase particular goods or services.

Geography The science that studies the terrestrial surface, the societies that inhabit it and the territories, landscapes, places or regions that form it

Geography is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of the Earth and planets. The first person to use the word γεωγραφία was Eratosthenes. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be.

Central place theory geographical theory explaining the number, size and location of human settlements in an urban system

Central place theory is a geographical theory that seeks to explain the number, size and location of human settlements in a residential system. The theory was created by the German geographer Walter Christaller, who asserted that settlements simply functioned as 'central places' providing services to surrounding areas.

Market (economics) mechanisms whereby supply and demand confront each other and deals are made, involving places, processes and institutions in which exchanges occurs (for physical venues, use Q132510 or Q330284)

A market is one of the many varieties of systems, institutions, procedures, social relations and infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services in exchange for money from buyers. It can be said that a market is the process by which the prices of goods and services are established. Markets facilitate trade and enable the distribution and resource allocation in a society. Markets allow any trade-able item to be evaluated and priced. A market emerges more or less spontaneously or may be constructed deliberately by human interaction in order to enable the exchange of rights of services and goods. Markets generally supplant gift economies and are often held in place through rules and customs, such as a booth fee, competitive pricing, and source of goods for sale.

Typically a low-order shop (such as a grocer or newsagent) may require only 800 or so customers, whereas a higher-order store such as Marks and Spencer or Waitrose may need a threshold of 70,000 to be profitable, and a university may need 350,000 to be viable. [2]

Thresholds may also be linked to the spending power of customers; this is most obvious in periodic markets in poor countries, where wages are so low that people can buy the goods or services only once in a while.

Supply-chain management management of the flow of goods and services, involves the movement and storage of raw materials, of work-in-process inventory, and of finished goods from point of origin to point of consumption

In commerce, supply-chain management (SCM), the management of the flow of goods and services, involves the movement and storage of raw materials, of work-in-process inventory, and of finished goods from point of origin to point of consumption. Interconnected or interlinked networks, channels and node businesses combine in the provision of products and services required by end customers in a supply chain. Supply-chain management has been defined as the "design, planning, execution, control, and monitoring of supply-chain activities with the objective of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronizing supply with demand and measuring performance globally." SCM practice draws heavily from the areas of industrial engineering, systems engineering, operations management, logistics, procurement, information technology, and marketing and strives for an integrated approach. Marketing channels play an important role in supply-chain management. Current research in supply-chain management is concerned with topics related to sustainability and risk management, among others. Some suggest that the “people dimension” of SCM, ethical issues, internal integration, transparency/visibility, and human capital/talent management are topics that have, so far, been underrepresented on the research agenda.

Poverty threshold Minimum income deemed adequate to live in a specific country or place

The poverty threshold, poverty limit or poverty line is the minimum level of income deemed adequate in a particular country. In practice, like the definition of poverty, the official or common understanding of the poverty line is significantly higher in developed countries than in developing countries. In 2008, the World Bank came out with a figure of $1.25 a day at 2005 purchasing-power parity (PPP). In October 2015, the World Bank updated the international poverty line to $1.90 a day. The new figure of $1.90 is based on ICP purchasing power parity (PPP) calculations and represents the international equivalent of what $1.90 could buy in the US in 2011. The new IPL replaces the $1.25 per day figure, which used 2005 data. Most scholars agree that it better reflects today's reality, particularly new price levels in developing countries. The common international poverty line has in the past been roughly $1 a day. At present the percentage of the global population living under extreme poverty is likely to fall below 10% according to the World Bank projections released in 2015, although this figure is claimed by scholars to be artificially low due to the effective reduction of the IPL in 2015

Retail is the process of selling consumer goods or services to customers through multiple channels of distribution to earn a profit. Retailers satisfy demand identified through a supply chain. The term "retailer" is typically applied where a service provider fills the small orders of a large number of individuals, who are end-users, rather than large orders of a small number of wholesale, corporate or government clientele. Shopping generally refers to the act of buying products. Sometimes this is done to obtain final goods, including necessities such as food and clothing; sometimes it takes place as a recreational activity. Recreational shopping often involves window shopping and browsing: it does not always result in a purchase.

Point of sale time and place where a retail transaction is completed

The point of sale (POS) or point of purchase (POP) is the time and place where a retail transaction is completed. At the point of sale, the merchant calculates the amount owed by the customer, indicates that amount, may prepare an invoice for the customer, and indicates the options for the customer to make payment. It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. After receiving payment, the merchant may issue a receipt for the transaction, which is usually printed but is increasingly being dispensed with or sent electronically.

Distribution is one of the four elements of the marketing mix. Distribution is the process of making a product or service available for the consumer or business user who needs it. This can be done directly by the producer or service provider, or using indirect channels with distributors or intermediaries. The other three elements of the marketing mix are product, pricing, and promotion.

Pricing process of determining what a company will receive in exchange for its products

Pricing is the process whereby a business sets the price at which it will sell its products and services, and may be part of the business's marketing plan. In setting prices, the business will take into account the price at which it could acquire the goods, the manufacturing cost, the market place, competition, market condition, brand, and quality of product.

Market segmentation is the activity of dividing a broad consumer or business market, normally consisting of existing and potential customers, into sub-groups of consumers based on some type of shared characteristics. In dividing or segmenting markets, researchers typically look for common characteristics such as shared needs, common interests, similar lifestyles or even similar demographic profiles. The overall aim of segmentation is to identify high yield segments – that is, those segments that are likely to be the most profitable or that have growth potential – so that these can be selected for special attention.

In theories of competition in economics, a barrier to entry, or an economic barrier to entry, is a fixed cost that must be incurred by a new entrant, regardless of production or sales activities, into a market that incumbents do not have or have not had to incur.

Inferior good good that decreases in demand when consumer income rises

In economics, an inferior good is a good whose demand decreases when consumer income rises, unlike normal goods, for which the opposite is observed. Normal goods are those goods for which the demand rises as consumer income rises. This would be the opposite of a superior good, one that is often associated with wealth and the wealthy, whereas an inferior good is associated with lower socio-economic groups.

Market penetration refers to the successful selling of a product or service in a specific market. It is measured by the amount of sales volume of an existing good or service compared to the total target market for that product or service. Market penetration is the key for a business growth strategy stemming from the Ansoff Matrix (Richardson, M., & Evans, C.. H. Igor Ansoff first devised and published the Ansoff Matrix in the Harvard Business Review in 1957, within an article titled "Strategies for Diversification". The grid/matrix is utilized across businesses to help evaluate and determine the next stages the company must take in order to grow, and the risks associated with the chosen strategy. With numerous options available, this matrix helps narrow down the best fit for an organization.

Shortage economic demand that exceeds supply

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).

Industrial market segmentation is a scheme for categorizing industrial and business customers to guide strategic and tactical decision-making. This especially is important in sales and marketing, as well. While government agencies and industry associations use standardized segmentation schemes for statistical surveys, most businesses create their own segmentation scheme to meet their particular needs, however.

The six forces model is an analysis model used to give a holistic assessment of any given industry and identify the structural underlining drivers of profitability and competition. The model is an extension of the Porter's five forces model proposed by Michael Porter in his 1979 article published in the Harvard Business Review "How Competitive Forces Shape Strategy". The sixth force was proposed in the mid-1990s. The model provides a framework of six key forces that should be considered when defining corporate strategy to determine the overall attractiveness of an industry.

Production leveling, also known as production smoothing or – by its Japanese original term – heijunka (平準化), is a technique for reducing the Mura (Unevenness) which in turn reduces muda (waste). It was vital to the development of production efficiency in the Toyota Production System and lean manufacturing. The goal is to produce intermediate goods at a constant rate so that further processing may also be carried out at a constant and predictable rate.

A marketing channel is the people, organizations, and activities necessary to transfer the ownership of goods from the point of production to the point of consumption. It is the way products get to the end-user, the consumer; and is also known as a distribution channel. A marketing channel is a useful tool for management, and is crucial to creating an effective and well-planned marketing strategy.

The European Union value added tax is a value added tax on goods and services within the European Union (EU). The EU's institutions do not collect the tax, but EU member states are each required to adopt a value added tax that complies with the EU VAT code. Different rates of VAT apply in different EU member states, ranging from 17% in Luxembourg to 27% in Hungary. The total VAT collected by member states is used as part of the calculation to determine what each state contributes to the EU's budget.

Bank financial institution

A bank is a financial institution that accepts deposits from the public and creates credit. Lending activities can be performed either directly or indirectly through capital markets. Due to their importance in the financial stability of a country, banks are highly regulated in most countries. Most nations have institutionalized a system known as fractional reserve banking under which banks hold liquid assets equal to only a portion of their current liabilities. In addition to other regulations intended to ensure liquidity, banks are generally subject to minimum capital requirements based on an international set of capital standards, known as the Basel Accords.

Economists and marketers use of the Search, Experience, Credence (SEC) classification of goods and services, which is based on the ease or difficulty with which consumers can evaluate or obtain information. These days most economics and marketers treat the three classes of goods as a continuum. Archetypal goods are:
