This paper investigates how CSR firms influence a Cournot oligopoly with pollution. We define as CSR a firm that takes into account not only its profits but also internalises its own share of the externality and is sensitive to consumer surplus. The CSR firm obtains higher profits compared to profit-seeking firms. Also, the presence of at least one CSR firm improves social welfare and makes the first best Pigouvian taxation more lenient for Cournot firms. Finally, the CSR firm may induce the other firms to invest in green technology.

The paper investigates how traits of cities explain subjective well-being and its subcomponents. Building up a happiness function, where life satisfaction is determined by satisfaction on life domains, the impact of city-level determinants of happiness is analyzed through a multilevel analysis. The results show that Italian cities have an effect on subjective well-being through different happiness domains. The relationship between the estimated coefficients of domain satisfactions and some relevant urban-context variables and amenities is then examined. This approach allows urban policy agendas to be designed around city-specific characteristics.
