Communication externalities in cities

Human Capital and Externalities in Cities

We combine growth theory with US Census data on individual schooling and wages to estimate the aggregate return to human capital and human capital externalities in cities. Our estimates imply that a one-year increase in average schooling in cities increases their aggregate labor productivity by 8 to 11 percent. We find no evidence for aggregate human capital externalities in cities however. Our...

Knowledge Externalities , Agglomeration Economies , and Employment Growth in Dutch Cities

This paper extends the work of Glaeser et al. (1992) by looking at effects of agglomeration economies on employment growth in Dutch city-industries and in very small (postal) zip code-industries in the Dutch province of South-Holland. At both levels of geographic detail, findings are broadly consistent with results from the earlier study in that employment growth is enhanced by industrial diver...

Groves mechanisms and communication externalities

We put forward a model of private goods with externalities. Agents derive benefit from communicating with each other. In order to communicate they need to operate on a common platform. Adopting new platforms is costly. We first provide an algorithm that determines the efficient outcome. Then we prove that no individually rational and feasible Groves mechanism exists. We provide sufficient condi...

Communication and Coordination in Games with Third-Party Externalities

Decision-makers in coordination problems often impose negative externalities on non-decision-making third parties. This thesis investigates whether the introduction of pre-play communication in such coordination problems can work to alleviate such negative externalities, consequently increasing group welfare. Unlike previous studies, we find no significant effect following the introduction of c...
