We study a stochastic dynamic game of process innovation in which firms can initiate and terminate R&D efforts and production at different times. We discern the impact of knowledge spillovers on the investments in existing markets, as well as on the likely structure of newly forming markets, for...

In the text-book model of dynamic Bertrand competition, competing firms meet the same demand function every period. This is not a satisfactory model of the demand side if consumers can make intertemporal substitution between periods. Each period then leaves some residual demand to future...

We characterize sequential (preemption) and simultaneous (coordination) equilibria, as well as joint-value maximizing (cooperation) solutions, in a model of investment timing allowing for externalities in both flow profits and investment costs. For two ex-ante symmetric firms, either preemption...

We model capacity-building investments in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through the addition of production units that are durable and lumpy and whose cost is irreversible. While building their capacity over time, firms compete à la...

In a continuous-time model with uncertain market development, two potential entrants detect a nascent demand only if it reaches a firm-specific threshold. Entry occurs by investing irreversibly before competing in quantities. When leadership in the investment stage implies a first-mover...

We study a new real options model of oligopolistic entry based on empirical evidence of demand for a new product growing over time and eventually falling. Yet, firms do not know ex ante when this can occur, which creates incentives to update information by delaying irreversible entry. By...

We analyze strategic relationships between buyers and sellers in markets with switching costs and dynamic uncertainty by investigating the scenario wherein a representative buyer trades with two foreign sellers located in the same foreign country. We show that, under exchange rate uncertainty,...

In stochastic and competitive environments, investors face an investment dilemma because the environments provide conflicting incentives. Empirical research reports various behaviors exhibited by investors, including voluntary concurrent investments, which are called bandwagon investments....
