Abstract Recently it has become clear that many technologies follow a generalized version of Moore's law, i.e. costs tend to drop exponentially, at different rates that depend on the technology. Here we formulate Moore's law as a correlated geometric random walk with drift, and apply it to historical data on 53 technologies. We derive a closed form expression approximating the distribution of forecast errors as a function of time. Based on hind-casting experiments we show that this works well… 

Dynamics of Technological Growth Rate and the Forthcoming Singularity

In this chapter, we consider the process of technological progress presenting one of the options for measuring its speed throughout the entire historical process. We find that the general dynamics of

Many policy decisions rely on predictions of how technology performance is likely to change as a function of time or of human efforts in research or manufacturing. In climate policy, such predictions

Data-Driven Investment Decision-Making: Applying Moore's Law and S-Curves to Business Strategies

A simple crossover point in performance is proposed which is based upon the technological improvement rates and current level differences for target and replacement technologies and signals when the market for a given technology will start to be rewarding for innovators.

Long-run dynamics of the U.S. patent classification system

It is argued that classification system changes and patent reclassification are common and reveal interesting information about technological evolution and that reclassified patents tend to be more cited than non-reclassified ones, even after controlling for grant year and class of origin.

Climate Econometrics: An Overview

Climate econometrics is a new sub-discipline that has grown rapidly over the last few years. As greenhouse gas emissions like carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) are a major

Using a cultural evolution approach, it is suggested that sudden changes in the organization of ITs depend on the high costs of maintaining and transmitting reliable information.

The mathematical structure of innovation

A simple model of recursive innovation in which technologies are made up of components and combinations of components can be turned into new components is introduced, and a formula for the extent to which technological recursion increases or decreases the likelihood of making new technologies is derived.

A case against the trickle-down effect in technology ecosystems

The results show limited trickle-down effect in the technology ecosystem, where the advance of the system technology is not able to automatically promote the performance of the component technology and the fundamental technology that constitute the system.



Statistical Basis for Predicting Technological Progress

The results show that technological progress is forecastable, with the square root of the logarithmic error growing linearly with the forecasting horizon at a typical rate of 2.5% per year.

Forecasting technological innovation

This work uses hindcasting to evaluate a variety of different hypotheses for technological improvement and derives analytically an upper bound to the rate of technology improvement given the condition of increasing revenue and shows empirically that all technologies fall within this derived bound.

What Can Past Technology Forecasts Tell Us About the Future

The Perils of the Learning Model for Modeling Endogenous Technological Change

There is a fundamental statistical identification problem in trying to separate learning from exogenous technological change and that the estimated learning coefficient will generally be biased upwards, which will bias optimization models to tilt toward technologies that are incorrectly specified as having high learning coefficients.

The Economic Implications of Learning by Doing

It is by now incontrovertible that increases in per capita income cannot be explained simply by increases in the capital-labor ratio. Though doubtless no economist would ever have denied the role of

Superexponential long-term trends in information technology

The measurement of durable goods prices

American business has recently been under fire, charged with inflated pricing and an inability to compete in the international marketplace. However, the evidence presented in this volume shows that

Debunking the Learning Curve

The learning curve relates manufacturing cost to cumulative production. It is shown that for every well-behaved learning curve there is a corresponding relationship between unit cost and the annual

Calculating Interval Forecasts

The distinction between a forecasting method and a forecasting model is expounded and some general comments are made as to why prediction intervals tend to be too narrow in practice to encompas...

A Theory of Progress Functions

Abstract Despite its applicability to a variety of phenomena and its demonstrated utility, a theoretical explanation of the progress function is generally lacking. The objective of this paper is to
