Are there regional spillovers from FDI in the Swiss manufacturing industry?

This paper examines whether there are signs of regional spillovers from FDI, although evidence is still very scarce. It hypothesizes that (a) the assessment of regional spillovers relies on a detailed analysis of these effects, according to the channels by which they occur (namely, increasing competition, worker mobility, and demonstration effects); (b) the size and the extent of these effects depend on the interaction between their channels and the levels of existing technological capacity of local firms; and (c) spillover benefits tend to occur in regions where local firms largely invest in absorbing the best foreign knowledge. Using detailed firm-level manufacturing data from Switzerland, we have found that local firms gain from the presence of foreign firms in their region, but lose out if the firms are located elsewhere. Competition-related spillovers appear to be fully absorbed by local firms, with high technological capacities; worker-mobility-related spillovers are fully absorbed by low technology firms; while demonstration-related spillovers are absorbed by all groups of firms with mid technology firms experiencing the larger benefit. In addition, our results demonstrate that only local firms which have invested largely in the absorptive capacity benefit from spillovers, stemming mainly from technology transfer. This benefit seems to occur at both regional level and outside.

Marketing Olive Oil Products in the Tunisian Local Market: The Importance of Quality Attributes and Consumers' Behavior

This article is, to the best of our knowledge, the first investigation of Tunisian olive oil consumer behavior by the use of the conjoint analysis technique. The conjoint experiment was based on carefully selected olive oil attributes: type, taste, color, packaging, region of origin, and price. The results have important implications to improve the marketing of olive oil in the local market by focusing on key preferred attributes. Consumers were found to prefer more extra-virgin, followed by virgin olive oil, to pomace oil. They also showed higher preference for green colored olive oil with strong flavored taste. Contrary to a common belief in Tunisia, the region of origin attribute did not show significant effect on consumers’ purchasing decisions. The results show also that Tunisian olive oil consumers are price sensitive and therefore any price strategy to introduce bottled products should take into account consumers’ preferences for bulk purchase.     

Are there demonstration-related spillovers from FDI?: Evidence from Switzerland

This paper examines whether there are signs of demonstration-related spillovers from foreign direct investment (FDI). It hypothesizes that the size and the extent of such benefits vary according to the level of the absorptive capacity of local firms. Using detailed firm data from Swiss manufacturing and services/construction, we find strong evidence for demonstration-related spillovers when (a) local firms are not far behind the technological frontier of the industry with a technological gap slightly greater than one, and (b) local firms demonstrate high investment in the absorptive capacity. The results are found to be more consistent in manufacturing than services/construction.
