- Facts and distortions in an endogenous growth model with physical capital, human capital and varietiesPublication . Sequeira, Tiago NevesThis article studies a model with physical and human capital accumulation and varieties. The model includes several distortions: duplication effects, spillovers, creative destruction, surplus appropriability, and an erosion effect. We show that the duplication effect in R&D is essential to make the model replicate several stylized facts linked with R&D. We evaluate the distance to the optimal solution, comparing the strength of each distortion.
- The effect of income on the energy mix: Are democracies more sustainable?Publication . Ramalho, Esmeralda A.; Sequeira, Tiago Neves; Santos, Marcelo SerraThis paper shows that the effect of income on the energy mix depends on the democracy level. We find that more democratic countries tend to depart from the hydroelectric power, oil, and geothermal sources of energy to rely on coal, natural gas, and modern renewable sources (nuclear, biomass, wind, and others). Less democratic countries tend to become more dependent on oil and natural gas with their own development. Moreover, the energy ladder transition from hydroelectric sources to natural gas appears to be escalated more quickly for less democratic countries. These transitions are thus more environmental friendly for more democratic countries than for less democratic ones. An extended multinomial fractional regression model is proposed to test and deal with the endogeneity of income.
