A Structural nonparametric reappraisal of the CO2 emissions-income relationships.

Relying on a structural nonparametric estimation, we show that CO2 emissions clearly increase with income at low income levels. For higher income levels, we observe a decreasing relationship, though not significant. We also find that CO2 emissions monotonically increases with energy use at a decreasing rate.Nonparametric triangular systems, EKC; Energy use; CO2 emissions.

Promoting clean technologies under imperfect competition

We develop a general equilibrium multi-sector vintage capital model with energy-saving technological progress and an explicit energy market to study the impact of investment subsidies on investment and output. Energy and capital are assumed to be complementary in the production process. New machines are less energy consuming and scrapping is endogenous. The intermediate inputs sector is modelled à la Dixit-Stiglitz (1977). Two polar market structures are considered for the energy market, free entry and natural monopoly. The impact of imperfect competition on the outcomes of the decentralized equilibria are deeply characterized. We identify an original paradox: adoption subsidies may induce a larger investment into cleaner technologies either under free entry or natural monopoly. However, larger diffusion rates do not necessarily mean lower energy consumption at equilibrium, which may explain certain empirical puzzles.Energy-saving technological progress; vintage capital; market imperfections; natural monopoly; investment subsidies

Promoting clean technologies: The energy market structure crucially matters

We develop a general equilibrium vintage capital model with embodied energy- saving technological progress and an explicit energy market to study the impact of investment subsidies on investment and output. Energy and capital are assumed to be complementary in the production process. New machines are less energy con- suming and scrapping is endogenous. It is shown that the impact of investment subsidies heavily depends on the structure of the energy market, the mechanism explaining this outcome relying on the tight relationship between the lifetime of capital goods and energy prices via the scrapping conditions inherent to vintage models. In particular, under a free entry structure for the energy sector, invest- ment subsidies boost investment, while the opposite result emerges under natural monopoly if increasing returns in the energy sector are not strong enough.Energy-saving technological progress; vintage capital; energy market; natural monopoly; investment subsidies

Share the love : parental bias, women empowerment and intergenerational mobility

This study provides empirical evidence and develops a model that captures the complex intra-household bargaining interactions and gender-based intergenerational occupational mobility. Using panel data from Nigeria, our estimates show that greater intra-household female bargaining power leads to greater intergenerational occupational mobility for sons more than daughters. Similarly, the median age at first marriage has a positive impact on occupational mobility for both daughters and sons. However, benefit is larger for sons. In the model, parental gender bias is modeled as non-pecuniary (psychic) cost – a representation of parents’ pessimistic attitude towards their children’s adulthood outcomes – which negatively affects the marginal benefit of investing in children’s human capital. The decision of parents is critical in determining children’s mobility and becomes the basis of gender-based differences in human capital investment and intergenerational persistence.http://www.elsevier.com/locate/jebohj2022Economic
