This article estimates what characteristics (e.g., location, number of casualties, and type of attack) are associated with an Islamic terrorist attack. This is established by identifying the significant determinants of the probability that an attack had been carried out by Islamic terrorists....

In this paper, we examine the determinants of low-wage employment in Portugal. For this purpose, we use a data file of the European Community Household Panel (ECHP) for the years 1998 and 1999. In order to take into account unobserved heterogeneity in the data, a random-parameter logit model is...

Evidence on productivity spillovers from FDI to domestic firms is ambiguous. Incorrect estimation procedures may be one of the sources for the contradictory results obtained in empirical studies on this subject. We observe that inadequacy of the estimation procedures leads to a severe...

Empirical evidence on productivity spillovers - a concept that embodies the fact that foreign enterprises own intangible assets which can be transmitted to domestic firms, thus raising their productivity level - is ambiguous. With a panel data set at the firm level for the Portuguese...

Single index models are frequently used in econometrics and biometrics. Logit and Probit models are special cases with fixed link functions. In this paper we consider a bootstrap specification test that detects nonparametric deviations of the link function. The bootstrap is used with the aim to...

The service innovation literature lacks empirical studies that focus on the links between service firms and universities. This paper aims to contribute to a better understanding of these links. This paper applies the Portuguese version of the Community Innovation Survey (CIS 2006) to obtain data...

The development of the broadband market is a key aspect of the economic and social growth of a country. However, despite the importance and the development of broadband market in Portugal in recent years, especially with the explosion of the number of mobile broadband accesses, the studies for...

This paper aims to establish whether geographical proximity between multinational and domestic firms is relevant to the occurrence of FDI spillovers, by considering both horizontal and vertical spillovers. Using data for Portugal, this hypothesis is confirmed. In the case of horizontal...
