Dynamic Stock Modelling
Dynamic stock modelling (DSM) is a new development in material flow accounting and explicitly considers the role of in-use stocks in past, present, and future material use. For resource use In-use stocks of buildings, infrastructure, and (durable) products play several important roles in social metabolism: * They supply physical services such as transportation or shelter to people. * They are 'capital containers' and 'resource repositories' representing large accumulations of fixed capital In accounting, fixed capital is any kind of real, physical asset that is used repeatedly in the production of a product. In economics, fixed capital is a type of capital good that as a real, physical asset is used as a means of production which i ... and materials; for example, steel and concrete in buildings. * They are 'dynamics determiners'; their lifetime determines replacement flows and when new technologies can penetrate the market. * They are 'wealth watchers' and can serve as an indic ...

Material Flow Accounting
Material flow accounting (MFA) is the study of material flows on a national or regional scale. It is therefore sometimes also referred to as regional, national or economy-wide material flow analysis. Introduction Material flow accounting provides economy-wide data on material use. Through international standardization, this data has become reliable and comparable across countries. Increasingly, the data are also being made available in medium- to long-term time series allowing for the analysis of past trends as well as potential future developments. Material flow accounts provide information on the material inputs into, the changes in material stock within, and the material outputs in the form of exports to other economies or discharges to the environment of an economy. Material flow accounting can be used in national planning, especially for scarce resources, and also allows for forecasting. The method can be used to assess environmental burdens associated with the economic activi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stock (variable)
Economics, business, accounting, and related fields often distinguish between quantities that are stocks and those that are flows. These differ in their units of measurement. A ''stock'' is measured at one specific time, and represents a quantity existing at that point in time (say, December 31, 2004), which may have accumulated in the past. A ''flow'' variable is measured over an interval of time. Therefore, a flow would be measured ''per unit of time'' (say a year). Flow is roughly analogous to rate or speed in this sense. For example, U.S. nominal gross domestic product refers to a total number of dollars spent over a time period, such as a year. Therefore, it is a flow variable, and has units of dollars/year. In contrast, the U.S. nominal capital stock is the total value, in dollars, of equipment, buildings, and other real productive assets in the U.S. economy, and has units of dollars. The diagram provides an intuitive illustration of how the ''stock'' of capital currently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Metabolism
Social metabolism or socioeconomic metabolism is the set of flows of materials and energy that occur between nature and society, between different societies, and within societies. These human-controlled material and energy flows are a basic feature of all societies but their magnitude and diversity largely depend on specific cultures, or sociometabolic regimes. El metabolismo social: una nueva teoría socioecológica. Relaciones. 2013. Social or socioeconomic metabolism is also described as "the self-reproduction and evolution of the biophysical structures of human society. It comprises those biop ...

Fixed Capital
In accounting, fixed capital is any kind of real, physical asset that is used repeatedly in the production of a product. In economics, fixed capital is a type of capital good that as a real, physical asset is used as a means of production which is durable or isn't fully consumed in a single time period.Varri P. (1987) Fixed Capital. In: Durlauf S., Blume L. (eds) The New Palgrave Dictionary of Economics. Palgrave Macmillan, London. "fixed capital", '' The New Palgrave: A Dictionary of Economics'', 1st Editio/ref> It contrasts with circulating capital such as raw materials, operating expenses etc. The concept was first theoretically analyzed in some depth by the economist Adam Smith in The Wealth of Nations (1776) and by David Ricardo in On the Principles of Political Economy and Taxation (1821). Ricardo studied the use of machines in place of labor and concluded that workers' fear of technology replacing them might be justified. Thus fixed capital is that portion of the total ...

Service (economics)
A service is an act or use for which a consumer, company, or government is willing to payment, pay. Examples include work done by barbers, doctors, lawyers, mechanics, banks, insurance companies, and so on. Public services are those that society (nation state, fiscal union or region) as a whole pays for. Using resources, skill, ingenuity, and experience, service providers benefit service consumers. Services may be defined as intangible acts or performances whereby the service provider provides value to the customer. Key characteristics Services have three key characteristics: Intangibility Services are by definition intangible. They are not manufactured, transported or stocked. One cannot store services for future use. They are produced and consumed simultaneously. Perishability Services are perishable in two regards: * Service-relevant resources, processes, and systems are assigned for service delivery during a specific period in time. If the service consumer does not request ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Assessment Modelling
Integrated assessment modelling (IAM) or integrated modelling (IM) is a term used for a type of scientific modelling that tries to link main features of society and economy with the biosphere and atmosphere into one modelling framework. The goal of integrated assessment modelling is to accommodate informed policy-making, usually in the context of climate change though also in other areas of human and social development. While the detail and extent of integrated disciplines varies strongly per model, all climatic integrated assessment modelling includes economic processes as well as processes producing greenhouse gases. Other integrated assessment models also integrate other aspects of human development such as education, health, infrastructure, and governance. These models are integrated because they span multiple academic disciplines, including economics and Climatology, climate science and for more comprehensive models also energy systems, land-use change, agriculture, infrastru ...
