We examine an infinite horizon model of quality growth for a durable goods monopoly. The seller may offer any bundle(s) of current and previous quality improvements (upgrades). Subgame perfect equilibrium seller payoffs range from capturing the full social surplus down to only the initial flow...

We analyse a set of simple dynamic models where sellers are capacity constrained over the length of the model. Buyers act strategically in the market, knowing that their purchases may affect future prices. The model is examined when there are single and multiple buyers, with both linear and...
