Computable general equilibrium models : a literature review
Menezes, António Gomes de; Fortuna, Mário; Silva, Francisco; Vieira, José CabralApplied general equilibrium models have become popular tools used on ongoing economic policy debates.

Supermarket site assessment and the importance of spatial analysis data
Mendes, Armando B.; Cardoso, Margarida G.M.S.; Oliveira, Rui CarvalhoThis work is part of a dissertation that addresses the supermarket site assessment problem. We propose a 3-steps method for stores' site evaluation. (The 1st step yields the constitution of analogue groups of existent supermarkets, using a clustering procedure. On the 2nd step we use classification trees to classify new stores into specific analogue groups. Finally, on the 3rd step, we build a linear regression...

Impacts of closure of a military base on a small island open economy
Fortuna, Mário; Bayar, Ali; Sisik, Suat; Mohora, Cristina; Rege, SameerMilitary bases are commonplace in many countries. Their economic impact on the neighbouring communities depends on their location and the level of integration of their activities on the local economies. Base closures or base activity reductions are also frequent as a consequence of military strategy alterations. The current paper seeks to analyse the economic impact of a US base located in the island of Terceir...

Todavia, somos da opinião de que “ (…) não existe, efectivamente, um verdadeiro Direito de Asilo na União Europeia, pelo menos, no sentido em que, tradicionalmente...
