Convergence and divergence in regional agricultural productivity growth: evidence from Italian regions, 1951–2002

This article analyzes long‐term agricultural Total Factor Productivity (TFP) growth at regional level by testing its time‐series properties and identifying factors associated with divergence as opposed to convergence. The empirical application concerns Italian regions over the 1951–2002 time period. TFP growth decomposition ultimately attributes the observed productivity growth performance to these contrasting (convergence vs. divergence) forces. We find that technological spillovers are the key convergence force regardless of how the spillover effects are computed. At the same time, forces favoring convergence are almost offset by divergence forces (mainly scale or learning effects). This decomposition may explain the persistence of TFP growth rate differences in Italian agriculture, and could be applicable elsewhere.

Pattern mining in tourist attraction visits through association rule learning on Bluetooth tracking data: A case study of Ghent,Belgium

The rapid evolution of information and positioning technologies, and their increasing adoption in tourism management practices allows for new and challenging research avenues. This paper presents an empirical case study on the mining of association rules in tourist attraction visits, registered for 15 days by the Bluetooth tracking methodology. This way, this paper aims to be a methodological contribution to the field of spatiotemporal tourism behavior research by demonstrating the potential of ad-hoc sensing networks in the non-participatory measurement of small-scale movements. An extensive filtering procedure is followed by an exploratory analysis, analyzing the discovered associations for different visitor segments and additionally visualizing them in ‘visit pattern maps’. Despite the limited duration of the tracking period, we were able to discover interesting associations and further identified a tendency of visitors to rarely combine visits in the center with visits outside of the city center. We conclude by discussing both the potential of the employed methodology as well as its further issues.

How Safe Are the Harbors?

Abstract

With the growth of e-commerce has come the need for businesses to provide protection of personal, private data collected from internet users and consumers. The United States has favored a policy of industry self-regulation, while the European Union (EU) has responded to its consumer demands for privacy protection regulations and enforcement. Faced with the critical need for a middle ground, the US has proposed “Safe Harbor Privacy Principles” as a means of compromise with the EU. This article explores the market context of the Safe Harbor Principles, the European reaction, and the probable impact on businesses.

An alternative approach to the monitoring of technological diffusion via foreign direct investment: evidence from the Greek manufacturing sector

The existing studies of foreign direct investment and the corresponding technological diffusion process that they generate, focus either on specific parameters of the production process in isolation, or they combine certain parameters to construct indices that are not consistent across studies. The present analysis proposes an alternative approach that captures the entire production process and multinational firms are viewed as the platform that transfers more advanced technologies to the host countries. As multinational firms are able to utilise more efficiently the available production process, an efficiency gap ensues between the domestically owned firms of a country and the multinational firms that operate in it. We capture and provide a measure and a monitoring mechanism of the technological diffusion process via foreign direct investment through the evolution of the efficiency gap between the two groups of firms whilst controlling for other variables that might contribute to such a gap. We apply our approach to the manufacturing sector of the Greek economy that experiences a consistent presence of foreign direct investment inflows over the time period 2001–2007.
