We develop a dynamic stochastic general-equilibrium model of science, education and innovation to explain the simultaneous emergence of innovation clusters and stochastic growth cycles. Firms devote human-capital resources to research activities in order to invent higher quality products. The...

Based on a stochastic dynamic model of a firm’s optimal innovativebehavior we derive a simultaneous equation system for product andprocess innovations with intertemporal spillover effects. We estimatevarious versions of the model with dichotomous innovation data at thefirm level by using a...

We study an asymmetric triopoly in a heterogeneous product market where quantity decisions are delegated to managers. The two biggest firms are commonly owned by shareholders such as index funds while the smallest firm is owned by independent shareholders. Under such a cross-holding owner...
