Culture and diversity in knowledge creation

Is the paradise of effortless communication the ideal environment for knowledge creation? Or, can the development of local culture in regions raise knowledge productivity compared to a single region with a unitary culture? In other words, can a real technological increase in the cost of collaboration and the cost of public knowledge flow between regions, resulting in cultural differentiation between regions, increase welfare? In our framework, a culture is a set of ideas held exclusively by residents of a location. In general in our model, the equilibrium path generates separate cultures in different regions. When we compare this to the situation where all workers are resident in one region, R & D workers become too homogeneous and there is only one culture. As a result, equilibrium productivity in the creation of new knowledge is lower relative to the situation when there are multiple cultures and workers are more diverse.
