Mapping general purpose technologies with patent data

General Purpose Technologies and Energy Policy

We employ a general purpose technology model with endogenous stochastic growth to simulate the effects of different energy policy schemes. An R&D sector produces endogenous growth by developing radical and incremental technologies. These innovations result in blueprints for capital intermediates, which require raw capital and either carbon or noncarbon-based fuels. A carbon tax therefore affect...

General Purpose Technologies and the Industrial Revolution

Did innovations in core processes during the Industrial Revolution tend to generate innovations in downstream technologies? Here a theoretical model examines the effect of a political shock in a non-innovating society in which there is high potential willingness to cooperate. The result is regional specialization in the innovation process by degree of cooperation. Tests with a Poisson specifica...

The Dynamic Effects of General Purpose Technologies on Schumpeterian Growth

General purpose technologies (GPTs) are drastic innovations, such as electrification, the transistor, and the Internet, that are characterized by the pervasiveness in use, innovational complementarities, and technological dynamism. The transitional and long-run dynamic effects of a GPT are analyzed within a quality-ladders model of scale-invariant Schumpeterian growth. The diffusion path of a G...

Input-Output Multipliers, General Purpose Technologies, and Economic Development

Intermediate goods are another produced factor of production, like capital. Simple examples suggest that the multiplier associated with intermediate goods can be substantial, even larger than the one resulting from physical capital accumulation. This paper evaluates this insight using a model in which N goods are produced using all of the other goods as intermediate inputs. Calibrating the mode...
