The Regional Input–Output Modeling System (RIMS II) is a regional economic model developed and maintained by the US Bureau of Economic Analysis (BEA).. Regional input–output multipliers such as the RIMS II multipliers allow estimates of how a one-time or sustained increase in economic activity in a particular region will impact other industries located in the region—i.e., estimating ...
In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies. [1] Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.
A shift-share analysis attempts to identify the sources of regional economic changes. The region can be a town, city, country, statistical area, state, or any other region of the country. The analysis examines changes in an economic variable, such as migration, a demographic statistic, firm growth, or firm formations, although employment is ...
The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. Many introductory programming and systems analysis texts introduce this as the most basic structure for describing a ...
Karen Rosel Polenske (born March 20, 1937) is an American regional economist specialized in energy, environmental, and infrastructure analyses, and input-output accounts and models, particularly at the subnational scale. She is currently the Peter de Florez Professor of Regional Political Economy at the Massachusetts Institute of Technology ...
Transfer function. In engineering, a transfer function (also known as system function[1] or network function) of a system, sub-system, or component is a mathematical function that models the system's output for each possible input. [2][3][4] It is widely used in electronic engineering tools like circuit simulators and control systems.
System identification techniques can utilize both input and output data (e.g. eigensystem realization algorithm) or can include only the output data (e.g. frequency domain decomposition). Typically an input-output technique would be more accurate, but the input data is not always available.
Comparison of instruction set architectures. An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture. A realization of an ISA is called an implementation. An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things ...
