We investigate a sample of 180 technology licensing contracts closed by German chemical, pharmaceutical, and electrical engineering companies between 1880 and 1913. A regression analysis shows that licensing contracts closed before a patent was granted and contracts closed between firms and...

We describe the transfer of patents in late 19th- and early 20th- century Germany using a new and comprehensive database containing information on about 20,000 transactions. The number of transactions shows an upward trend, in total numbers and as a share of patents in force. In total, about...

We investigate a sample of 180 technology licensing contracts closed by German chemical, pharmaceutical, and electrical engineering companies between 1880 and 1913. Our empirical results suggest that strategic behaviour seems to be relevant for the design of licensing contracts, whereas inventor...

Open source software (OSS) is a public good. A self-interested individual would consider providing such software, if the benefits he gained from having it justified the cost of programming. Nevertheless each agent is tempted to free ride and wait for others to develop the software instead. This...
