Learning from Trade through Innovation

This paper explores the idea that firms learn from trade by introducing either new products or processes influenced by their trade links with foreign markets. By exploring microdata for Spain, including data on innovation and trade, we find a robust relationship between imports, exports and innovation. The results suggest that firms learn primarily from import links, which enable them to innovate and to ‘dress up’ for starting to export. This sequencing between trade and innovation, however, is shown to be more pronounced for small firms only and technologically advanced firms.     

Uhljeb – a post-socialist homo croaticus: a personification of the economy of favours in Croatia?

Party patronage combined with a collectivist culture appears to present a very resistant socialist legacy in Croatia. In-group favouritism and an overly bureaucratised system provide a fertile soil for uhljebs. An uhljeb is a public sector employee whose main ‘competence’ is membership of a political party or a nepotistic relationship. They now already count in the thousands, and often contribute to the further multiplication of uhljebs, and to an increase in clientelist arrangements. The practice of employing uhljebs both undermines and underpins the existing system. That ambivalence is one of the characteristics of the Russian sistema, and that is one of the important links to compare blat users and uhljebs, in addition to the practice of ‘pulling strings’. As key protagonists, uhljebs and blat users illustrate their own and society’s modus operandi: an intense ‘economy of favours’. Recent studies increasingly show that cultural variables influence economic outcomes and this article presents an extension of the ‘economy of favours’ into Croatia’s paradigm. Based on primary sources and international benchmarks, it provides a comparison of the cultural contexts of Eastern and Western European countries, and portrays a rising informal practice that, despite its omnipresence, has been under-researched in the academic literature.     

Exploring combined tourist offerings: the case of sightrunning

This study provides preliminary empirical insight into the contemporary tourist phenomenon of sightrunning. This combined offering simultaneously concurs with and evades theoretical perspectives of hybrid tourists, sport tourism, cultural tourism and urban tourism, favouring examination of such phenomena through first-hand experiences of the participants. For the purpose of the empirical study, automated content analysis was applied in order to analyse 858 reviews of sightrunning tours extracted from Tripadvisor web pages. Results reveal that running is the dominant concept, which refers to a gratifying ‘way to see and experience the city’ (rather than the sights). Additional concepts and themes, such as knowledgeable guides and proper pace, further mediate and effect participant experiences. Findings suggest that sport tourists might be concurrently interested in involving cultural experiences, and this offers some preliminary theoretical and managerial implications. They namely identify the potentially neglected tourist segment, which is of relevance for conceptualization, research and management of tourist offerings and experiences from (and beyond) the perspective of ‘running shoes’.     

Foreign News and Spillovers in Emerging European Stock Markets

We analyze foreign news and spillovers in the emerging EU stock markets (the Czech Republic, Hungary, and Poland). We employ high‐frequency five‐minute intraday data on stock market index returns and four classes of EU and US macroeconomic announcements during 2004–07. We account for the difference of each announcement from its market expectation and we jointly model the volatility of the returns accounting for intraday movements and day‐of‐the‐week effects. Our findings show that intraday interactions on the new EU markets are strongly determined by mature stock markets as well as the macroeconomic news originating thereby. We show that strong contemporaneous links across markets are present even after controlling for macroeconomic announcements. Finally, in terms of specific announcements, we are able to show the exact sources of macro news spillovers from the developed foreign markets to the three new EU markets under research.     

Privatization,market competition,international attractiveness,management tenure and hotel performance: Evidence from Slovenia

This paper tests several hypothesis related to the impact of privatization, market competition, management tenure and international attractiveness on the cost efficiency of tourist hotels. We measure efficiency using the innovative Bayesian frontier methodology. The data involve a sample of Slovenian hotels which operate in a highly dynamic environment. From the results, it is clear that hotel efficiency is positively related to privatization and international attractiveness, and negatively related to longer management tenure. No significant link, on the other hand, is found between market competition and hotel efficiency. Further discussions of these findings and related managerial implications are provided.     

The influence of the political environment and destination governance on sustainable tourism development: a study of Bled,Slovenia

In the context of sustainable tourism development, there are many studies about the exchange process between residents and tourism, yet this issue is practically unexplored with respect to the political environment of tourism. Therefore, this paper introduces and posits that the political environment is a necessary enabler for implementing sustainable tourism. The authors extend the established three-pillar sustainability concept by adding in the political dimension. Then they surveyed how residents' positive and negative perceptions of tourism impacts determine their satisfaction with life in the tourism destination and thus their support for tourism in their community. The model was empirically tested within the context of the long-established Alpine destination of Bled in Slovenia. The findings confirm the importance of the political environment and question the sustainability of Bled's tourism development. It is suggested that the community has relatively weak destination governance due to the underdeveloped political environment. The survey expands and deepens the tourism sustainability debate by adding in the political environment and how it relates to the emerging growth of research on destination governance. The proposed model can be adapted and applied to any destination in order to improve its governance, including the implementation of sustainable tourism development.     

Variable neighborhood search heuristic for nonconvex portfolio optimization

Abstract

In this article we consider a portfolio optimization problem under multiple real-world constraints, such as: cardinality constraints, tracking error, active share, and turnover. We propose a heuristic based on variable neighborhood search (VNS) that effectively addresses additional constraints that introduce non-convexities. In the VNS-based heuristic, several neighborhood structures are introduced and fast local search is implemented. We develop a VNS portfolio rebalancing framework (VNS-PRF) with two rebalance strategies. Data sets provided by a financial investment firm are used to evaluate the validity and reliability of the proposed VNS-PRF. Computational experiments and different portfolio performance measures indicate that our approach is able to obtain solutions with competitive quality and can be applied on large-scale data sets.     

Mobile Dwelling Unit Developed by a Group of Mechanical Engineering Design Students

The increasing number of homeless people is one of the most burning problems of nowadays world. Society has to find the way to fight against it and provide help to those people that have no place to stay. For short-term interventions, the application of the mobile dwelling units seems to be the only possible solution. However, existing mobile dwelling units are rather limited to specific areas of application. A group of students faced this problem and decided to develop an alternative, more universal mobile dwelling unit that will fulfil a wide range of different technical and social requirements at a reasonable price. The paper describes a systematic approach to development of the mobile dwelling unit, which was performed as a part of the education process at the Faculty of Mechanical Engineering, University of Maribor. The project presented is interdisciplinary. In addition to the educational aspect that is emphasized in this paper, technical, economic and social aspects of the project have also a very important role. From educational point of view, the project was concluded successfully. Moreover, we believe our proposal for a mobile dwelling unit is both novel and suitable for general application. This revised version was published online in July 2006 with corrections to the Cover Date.     

Macroeconomic sources of foreign exchange risk in new EU members

We address the issue of foreign exchange risk and its macroeconomic determinants in several new EU members. We derive the observable macroeconomic factors—consumption and inflation—using the stochastic discount factor (SDF) approach. The joint distribution of excess returns in the foreign exchange market and the factors are modeled using a multivariate GARCH-in-mean specification. Our findings show that both real and nominal factors play important roles in explaining the variability of the foreign exchange risk premium. Both types of factors should be included in monetary general equilibrium models employed to study excess returns. To contribute to the further stability of domestic currencies, the new EU members should strive to implement stabilization policies aimed at achieving nominal as well as real convergence with the core EU members.
