We introduce a neighborhood structure in waiting games where the players decide when to "stop" (exit a market, adopt a technology). The payoff of stopping increases each time a neighbor stops. We show that the dynamic evolution of the network starkly depends on initial parameters and can take...

We analyze the optimal investment strategy of a firm that can complete a project either in one stage at a single freely chosen time point or in incremental steps at distinct time points. The presence of economies of scale gives rise to the following trade-off: lumpy investment has a lower total...
