A number of empirical studies have shown that culture matters for economic outcomes. Yet, the mechanisms through which culture affects economic variables are far less understood. I model cultural transmission and economic process as two interacting phenomenons by use of the micro-funded model of cultural transmission introduced in Bisin and Verdier (2001). This model combines purposeful transmission by parents and passive transmission by peers. Since the socialization decision by parents depends on a trade-off between some costs and benefits, socialization rates depend on other variables (e.g social composition of the population, prices, incomes). This is particularly well-suited to the study of co-movements of cultural, social and economic variables. I first apply this model to the study of capital-pollution accumulation. My model provides an economic rationale for the gap between the number of people who care about the environment (i.e. environmental attitudes) and the number who adopt pro-environmental behaviours as well as the negative relationship between this gap and countries' income. Second, I study interactions between cultural transmission of preferences for eco-friendly products and innovation in environmentally friendly sectors. I show the existence of a race between preferences and the technology which explains different stylized facts on "green" markets (i.e success of bioplastics, failure of electric cars). Finally, I develop a model where preferences for education and neighbourhood formation are endogenous. It allows me to study the relationship between intergenerational mobility and urban segregation. I show that the joint dynamics of segregation and distribution of traits in the whole population exhibits multiple history-dependent steady-states, that is, the initial rate of education in the society matters for the relationship between intergenerational social mobility urban segregation.
