Random walk to innovation: Why productivity follows a power law
In this paper we propose a mechanism generating endogenously the productivity of innovations. We assume that knowledge creation occurs as the innovator obtains new ideas from combinations of existing ideas. The productivity of an innovation is determined by an unobservable intrinsic component as well as by the productivity of the parent ideas and their parents, thus generating a network of spil...
متن کاملConsistent Estimation and Inference When Data Follows a Power Law∗
Power laws are common in economic phenomena, such as the size of cities and firms. When they occur, these power laws can cause estimates of economic quantities to have extremely different variances when those quantities observed at an aggregate level (for example, at the city or firm level). I show that in general, estimators based on observations exhibiting this extreme heteroskedasticity may ...
متن کاملDivergence pattern of duplicate genes in protein-protein interactions follows the power law.
The impact of the biological network structures on the divergence between the two copies of one duplicate gene pair involved in the networks has not been documented on a genome scale. Having analyzed the most recently updated Database of Interacting Proteins (DIP) by incorporating the information for duplicate genes of the same age in yeast, we find that there was a highly significantly positiv...

In this paper we propose a mechanism generating innovations with productivity distributed according to a power law. We assume that knowledge creation occurs as new ideas are produced from combinations of existing ideas. The productivity of an innovation is determined by an unobservable intrinsic component as well as by the productivity of the parent ideas and their parents, thus generating a ne...
