Technological progress builds upon itself, with the expansion of invention in one domain propelling future work in linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its strength. Past innovation network structures are...

Firms can use different sources of external knowledge for developing and implementing innovations. Some knowledge is provided deliberately by the source and constitutes intended knowledge spillovers, e.g., knowledge disclosed in publications or patent files. Other sources represent unintended...

This paper is the first to employ multiple outputs, patents and net sales, in our data envelopment analysis (DEA) to examine whether operational efficiency improves after enterprise resource planning (ERP) installations. The ANOVA analysis results show that granted patent number significantly...

At least since Schumpeter published his work "The Theory of Economic Development" (1912), a wide body of literature has focused on the evolutionary process behind firm growth and survival. Recently a growing interest is devoted to the variable "location" as a critical factor, shaping firm...

Network analysis shows a stable network between states, but a changing environment between individual actors, with a growing importance of connectedness. The popular maxim that everyone is connected by six degrees of separation is tested with surprising results

This article presents an empirical model of non-stationary and cointegrated panel data to explain the impact of industrial property, measured by patents, on the GDP of 10 Latin America countries during the period 1990 to 2010. Apply traditional unit root tests and unit root test of art, which...
