The Azorean Government embarked on a public-private partnership to build a road on the island of São Miguel, to circumvent the budget restriction imposed by the central government. We build a sequentially dynamic general equilibrium model with forty- five sectors and six household categories to measure the welfare changes arising from the project. The initial investment is amortised over a period and the payments are simulated through an increase in income taxes, reduction in transfer payments or calculating the fall in transport margins. We find that under any type of repayment scheme the welfare benefits do not justify the road construction thus making it a poor investment decision.

A teoria, a análise e políticas de habitação têm como âmbito territorial 3 escalas diferenciadas de aplicação, o nível nacional, o regional e o urbano. Em qualquer um destes níveis a análise hedónica de preços tem sido amplamente divulgada, na medida em que permite, com base em modelos de regressão estatísticos, perceber quais os atributos, quer físicos quer locacionais, mais importantes na explicação do preço de um imóvel. Contudo, há uma vasta bibliografia que considera os métodos estatísticos convencionais ineficazes para avaliar modelos de regressão espacial. Com vista a ultrapassar algumas das fragilidades dos modelos hedónicos, este artigo visa apresentar os desenvolvimentos metodológicos de incorporação dos aspectos espaciais nos modelos de avaliação de preços da habitação residencial, bem como apresentar alguns resultados que ilustrem a sua aplicação ao centro urbano de Aveiro.

The aim of this paper is to present a Performance Indicators Model (PIM) in order to evaluate and compare industrial districts development. Several models were compared to the proposed one, in order to show the advantages/disadvantages of the PIM. Disposing of an indicators dashboard allows the convergence and the robustness of operations districts results verification in respect of expected outputs(questa frase non l’ho capita). Thanks to this model the public entities could dispose of a unique instrument to compare the Industrial Italian Clusters (probabilmente Italian va prima di industrial) (IIC) awarding and supporting those more worthy of trust.

PERIPHERIES: CHALLENGES ON THE OTHER SIDE OF CENTRALITY
Virtudes, Ana (virtudes@ubi.pt)
Universidade da Beira interior

This article aims at analyzing the problem of urban peripheries understanding as the other side of the city whose spatial structure clearly responds to a model based on the dichotomy between centre and periphery.
1. It is about the formation of the modern city, from processes and mechanisms that cause a spatial model with a unique centre in dichotomy with the peripheral areas.
2. It is in a cultural context of the rising of bourgeois class whose social project for the city meant making urban transformations. The other part of the city was delivered to the lower or "inferior" working classes.
3. It reflects the reality of today's urban peripheral areas, such as new residential areas, increasingly dispersed, with new equipment and attractive shopping centres, fed by the dream of being owners of small portions of even little bits of territory, which Joel Kotkin describes as the dream of the vassal of having its own castle.

This research aims at studying the determinants of entrepreneurship, focusing on the special case of firms created within Business and Innovation Centre (BIC) in Portugal. For that purpose, we developed a survey to the firms created within Portuguese BICs. Our results show that the respondent firms were quite different from the Portuguese typical firms, as in our case, most firms have a medium or high technological intensity and the entrepreneur has a higher education level. However, there is some parallel with most Portuguese firms, as in both cases there is evidence of an endogenous entrepreneurship, either spatial or functional. From our results, we were able to conclude that entrepreneurs welcome BICs’ support when starting the firm but also during its growth. Finally, most entrepreneurs classified BICs’ services as being above their expectations.
