Impact of Information Technology Investments on Firm Productivity in Peripherals Countries: The Case of Portugal

IS/IT investments are seen has having an enormous potential impact on the competitive position of the firm, on its performance, and demand an active and motivated participation of several stakeholder groups. The shortfall of evidence concerning the productivity of IT became known as the ‘productivity paradox’. As Robert Solow, the Nobel laureate economist stated “we see computers everywhere except in the productivity statistics”. An important stream of research conducted all over the world has tried to understand these phenomena, called in the literature as «IS business value» field. However, there is a gap in the literature, addressing the Portuguese situation. No empirical work has been done to date in order to understand the impact of Information Technology adoption on the productivity of those firms. Using data from two surveys conducted by the Portuguese National Institute of Statistics (INE), Inquiry to the use of IT by Portuguese companies (IUTIC) and the Inquiry Harmonized to (Portuguese) companies (accounting data), this study relates (using regression analysis) the amounts spent on IT with the financial performance indicator Returns on Equity, as a proxy of firm productivity, of Portuguese companies with more than 250 employees. The aim of this paper is to shed light on the Portuguese situation concerning the impact of IS/IT on the productivity of Portuguese top companies. Empirically, we test the impact of IT expenditure on firm productivity of a sample of Portuguese large companies. Our results, based on firm-level data on Information Technology expenditure and firm productivity as measured by return on equity (1186 observations) for the years of 2003 and 2004, exhibit a negative impact of IT expenditure on firm productivity, in line with “productivity paradox” claimants.

Conservation biogeography of ecologically interacting species: The case of the Iberian lynx and the European rabbit

Aim To relate the recent Iberian lynx decline to changes in the distribution of the European rabbit after the haemorrhagic disease outbreak of 1989. As Iberian rabbits evolved in two geographically separated lineages, being the recent lynx range practically restricted to the southwestern lineage, we also test if differential range dynamics exists for these lineages, with the consequent implications for lynx conservation and reintroduction planning.

Steady tourists’ relationship with a mature destination. The case of Portugal

This article assesses how the last-visit features and the socio-demographic profile of tourists moderate repeat-visit patterns to Portugal, a mature destination where the persistence of loyal visitors has made its mark on tourism development. The methodology used is a survival analysis to assess the tourists’ repeat patterns. To test the model, a database of 4612 observations was employed, which was obtained from a survey of international tourists. Only repeat visitors with more than two visits over the years were considered for the purpose of the research. The study finds that a combination of socio-demographic characteristics, expectation/satisfaction, trip purpose, pull motivations and regional destination has a positive effect on repeat patterns, confirming that tourists’ willingness to repeat visits to Portugal is far from ceasing. Based on those tourists to Portugal who declared when they started to visit the country, and the number of years of their repeat visits, the article contributes to the literature by introducing new methods of assessing tourists’ repeat patterns for destinations.
