This work focuses on assessing the potential for generation of biomass residues from agroforestry sources in a region of Portugal (Alto Alentejo), within the scope of energy valorization of the biomass by means of combustion technologies. The model uses a GIS-based method to estimate the...

A 2-D numerical model based on the Computational Fluid Dynamic (CFD) framework was developed to investigate the influence of oxygen-enriched air on a biomass gasification process. Both gas and solid phases were described using and Eulerian–Eulerian approach exchanging mass, energy and...

The major distinctive feature of cultural goods is that consumers must learn how to consume them, implying that preferences should be modelled as intertemporally dependent. The canonical model in the literature uses a habit formation analogy. In this paper, we discuss in detail, though in the...

An extension to the Yaari (1965)-Blanchard (1985) continuous time overlapping generations model for an endowment Arrow-Debreu economy with an age-structured population is presented. It is proved that Arrow-Debreu equilibrium prices are represented by a double linear integral equation, and depend...

We consider a two-sector endogenous growth model where the productions of the final good and human capital require economy-wide external effects. Assuming constant returns to scale at the private and social levels, we show that local and global indeterminacy of equilibrium paths are compatible...

In this paper we consider the entry and exit of firms in a Ramsey model with capital and an endogenous labour supply. At the firm level, there is a fixed cost combined with increasing marginal cost, which gives a standard U-shaped cost curve with optimal firm size. The costs of entry (exit) are...
