This paper sheds light on how changes in the organization of work can help to understand increasing wage inequality. We present a theoretical model in which workers with a wider span of competence (higher level of multitasking) earn a wage premium. Since abilities and opportunities to expand the...

The evolution during the Anthropocene is analyzed through the interaction between economic and technological development, characterized by the role of fossil fuels and by the progressive dominance of those with a higher energy and density power. The challenge is how to make the rising demand for...

We analyze some macroeconomic implications that follow from the fact that people tend to consume higher-quality goods as their incomes rise. The model involves two sectors: one producing a homogeneous good and the other producing a product with variable levels of quality. Both sectors use...

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy...
