The analysis shows that the volatility of a potential entrant's innovation is an important parameter which shapes an incumbent supplier's exclusivity strategy. Higher volatility encourages the incumbent supplier to adopt an accommodation, rather than a pure exclusion, strategy. When volatility...

Output-based allocations (OBAs) are typically used in emission trading schemes to mitigate leakage in sectors at risk. Recent work has shown they may also help to stabilize prices in markets subject to supply and demand shocks. We extend previous work to simultaneously include both leakage and...

We model cartel defection in markets with stochastic demand fluctuations as an investment timing problem. We show that (i) the optimal timing of cartel defection is pro-cyclical, suggesting higher probability of competitive pricing during booms; and (ii) the defection trigger is a positive...

Commodity markets are characterized by large volumes of forward contracts as well as high volatility. They are often accused of weak competitive pressure. This article extends the existing literature by analyzing tacit collusion of firms, forward trading and volatility simultaneously. The...

I model the optimal semi-collusive strategy of firms using forward contracts in volatile markets. It has been shown that forward contracts can be used to stabilize a collusive agreement under deterministic (Liski and Montero, 2006) as well as under stochastic market conditions (Aichele, 2012)....
