In this work we analyse patterns of technological development using patent applications at the United States Patent and Trademark Office (USPTO) over the 1973-2012 period. Our study focuses on the combinations of technological fields within patent documents and their evolution in time, which can...

The literature has identified a number of determinants of energy efficiency measures (EEMs) in firms, such as investment costs, expected profitability, the level of information and firm size. Instead of contributing a comprehensive analysis of this sort this paper theoretically and empirically...
