This paper studies the e¤ects of income heterogeneity on monopolistically competitive product markets and welfare in the context of non-homothetic preferences. When richer individuals expenditures are less sensitive to price change compared to poorer ones , a mean-preserving contraction of income distribution entices rms to charge higher prices, new rms enter and broaden product diversity. General equilibrium e¤ects have a negative impact on poorer individuals and, in speci c circumstances, on whole population. In open economies, lower income inequality in a country creates a price divergence between countries and decreases trade volumes and values. Those general equilibrium e¤ects are quantitatively non negligible. [less ▲]

This paper investigates the impact of local traffic pollution on the formation of residential and business districts. While firms benefit from local production externalities, households commute to their workplaces with private vehicles and exert a local pollution externality on the residents living along the urban transport networks. The spatial location of firms and residents endogenously results from the trade-off between the production and pollution externalities and the commuting costs. The analysis shows that in monocentric cities the benefits associated with a fall in per-vehicle pollution are absorbed by rents paid to absentee landlords. When a city includes business and residential districts as well as a district mixing both agents, a lower per-vehicle pollution enlarges the residential districts and shifts the business districts closer to the geographical center of the city. The paper finally studies the optimal city structure. The first-best policies that fully internalize the externalities still foster business agglomeration. [less ▲]

This paper discusses the impact of conformism on product quality, firm selection, and trade patterns. It shows that when consumers have a higher degree of conformism and/or their distribution of conformism becomes more concentrated, the equilibrium average demand falls while product quality rises in a closed economy. In an international trade context, this strengthens the home consumption bias when consumers conform to the behavior of local people. The home bias is mitigated under globalization where individuals tend to conform to people worldwide. The paper also discusses the conditions under which conformism and conspicuousness are reconciled. [less ▲]
