We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city...

In this paper, we investigate the impact of peers on own outcomes where all agents embedded in a network choose more than one activity. We develop a simple network model that illustrates these issues. We differentiate between the ‘seemingly unrelated’ simultaneous equations model where...

We develop a model of competing diffusions of goods on a social network. There are two types of goods and individuals: mass-market (more prevalent) and niche-market. We start with a general threshold rule and show that multiple equilibria prevail. Then, when everyone uses a single friend...

We consider a model where each individual (or ethnic minority) is embedded in a network of relation-ships and decides whether or not she wants to be assimilated to the majority norm. Each individual wants her behavior to agree with her personal ideal action or norm but also wants her behavior to...

We develop an urban-search model in which firms post wages. When all workers are identical, the Diamond paradox holds, i.e. there is a unique wage in equilibrium even in the presence of search and spatial frictions. This wage is affected by spatial and labor costs. When workers differ according...
