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...

This paper presents a dynamic random effects probit model for the realization of private firms’ product and process innovations. We estimate the model with panel data collected by the Ifo Institute in Munich. The data covers the period between 1979 and 1986 and includes 301 firms of the West...
