We show that time-to-build, which creates a lag between the decision to invest and production, is an important element of industry structure. We study a multi-period investment game where there is demand uncertainty. Allowing for time-to-build alters, non-monotonically, the classic trade-off...

We show that time-to-build, which creates a lag between the decision to invest and production, is an important element of industry structure. We study a multiperiod investment game where there is demand uncertainty. Adding time-to-build to the model alters the classic tradeoff between making...

We develop a novel approach to the dynamics of business strategy that is grounded in an explicit treatment of consumer choice when technologies improve over time. We address the evolution of market boundaries, resource rents and competitive positions by adapting models of competition with...

We study how diversity evolves at a firm with entry-level and upper-level employees who vary in ability and "type" (gender or ethnicity). The ability of entry-level employees is increased by mentoring. An employ receives more mentoring when more upper-level employees have the same type. Optimal...

This paper studies the forces which determine how diversity at a firm evolves over time. We consider a dynamic model o a single firm with two levels of employees, the entry level and the upper level. In each period, the firm selects a subset of the entry-level workers for promotion to the upper...

We formalize the phenomenon of disruptive technologies (Christensen, 1997) that initially serve isolated market niches and, as they mature, expand to displace established technologies from mainstream segments. Using a model of horizontal and vertical differentiation with discrete customer...

The authors study the relationship between asset prices and herd behavior, which occurs when traders follow the trend in past trades. When traders have private information on only a single dimension of uncertainty (the effect of a shock to the asset value), price adjustments prevent herd...
