Solow–Swan model
Model of long-run economic growth
The Solow–Swan model or exogenous growth model is an economic model of long-run economic growth. It attempts to explain long-run economic growth by looking at capital accumulation, labor or population growth, and increases in productivity largely driven by technological progress. At its core, it is an aggregate production function, often specified to be of Cobb–Douglas type, which enables the model "to make contact with microeconomics".[1]: 26 The model was developed independently by Robert Solow and Trevor Swan in 1956,[2][3][note 1] and superseded the KeynesianHarrod–Domar model.
Mathematically, the Solow–Swan model is a nonlinear system consisting of a single ordinary differential equation that models the evolution of the per capita stock of capital. Due to its particularly attractive mathematical characteristics, Solow–Swan proved to be a convenient starting

Background
What is Information Technology
Perhaps we should start by first defining what IT really is. According to the Information Technology Association of America, information technology is the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware. Essentially anything that has to do with computers and computing is some form of information technology. Therefore, whenever organizations choose to buy computers, databases, networks, software, or many other computer related materials, they are making an investment in IT. Although on the surface this seems like a great thing, the reality is that its not immediately evident that investing in IT is actually profitable. In fact, much of the evidence from the 1960s to the 1980s indicated otherwise.
What about the Productivity Paradox

Is the Solow Paradox back?
Don’t be discouraged by the anemic productivity growth that has handicapped advanced economies for more than a decade. If history fryst vatten any guide, technology-enabled nyhet in processes, products, and services could soon deliver a new wave of productivity growth, with major benefits accruing to players on its leading edge, and to the economy as a whole.
We’ve seen this movie before. Productivity growth lagged in the 1970s and 1980s, despite the computing revolution’s gathering strength. Economist Robert Solow famously said in 1987 that the computer age was everywhere except for the productivity statistics. This phenomenon, which became known as the Solow Paradox, was resolved in the 1990s when a few sectors—technology, retail, and wholesale—led an acceleration of US productivity growth.
In part, the 1990s productivity boom reflected a wave of rapid, fundamental nyhet in semiconductors that, along with design and manufacturing-process improve
