We present a fairly general model in which firms are competitors in a commercial market segment and can invest into a complementary public good like open source software. We show that, contrary to standard predictions, additional contribution to the public good by the government or a new market...

This paper analyzes an infinite horizon dynamic duopoly with stochastic demand in which firms face costs of absorbing and processing information. Our main result is that the structure of dates at which firms choose to absorb information differ starkly between price and quantity competition....

If duopolistic firms can choose their strategy variable, uncertainty about demand conditions and the degree of substitutability have countervailing effects on variable choice. High uncertainty favors prices, while close substitutability favors quantities. For intermediate values, a hybrid...

This paper analyzes a duopoly model with stochastic demand in which firms first choose their strategy variable and compete afterwards. Contrary to the existing literature, we show that firms do not always choose a quantity which is the variable that induces a smaller degree of competition. The...

"This paper analyzes a duopoly model with stochastic demand in which firms first commit to a strategy variable and compete afterwards. We find that in equilibrium the relative magnitude of demand uncertainty and the degree of substitutability determines firms' variable choice. Firms set prices...
