Search model with firm decision I am wondering if there is any work in search models that discusses firm behaviors. Most common search models that I am familiar with talk about the job seeker's threshold rule. Is there any model that discusses similar firm threshold rule, in investment in capital, effort etc.
The Neo-Schumpeterian literature models firm behavior with "an search and select" approach. Nelson and Winter (2009) where the pioneers in the subject, it is a pleasant and interesting reading.
