We examine in a laboratory experiment whether R&D cooperation facilitates tacit price collusion. For two scenarios of technological spillovers, a baseline treatment without binding contract possibilities and a contract treatment where it is possible to credibly commit to an R&D contract, are run. We find that the degree of price collusion in the contract treatments is significantly higher in periods where R&D contracts are made than in periods without contracts, and than in the baseline treatments.
