Jobs and Exposure to International Trade within the Service Sector in Sweden

To establish in which service industries there is international trade (or it may potentially exist), we calculate locational Ginis for different industries. The basic idea is that from this measure of regional concentration of different activities within a country we can identify industries where there appears to be regional trade, and hence also a potential for international trade. Based on our method, we find that: (i) the number of employed in tradable service appears to be at least as large as in the manufacturing sector, (ii) tradable service is much more skill intensive than manufacturing, and (iii) lately, the employment in tradable service has increased substantially. We argue that the last mentioned result is consistent with the substantial growth of skilled labour in Sweden since the mid‐1990s (Rybczynski effect) and factors leading to increased relative demand for skilled labour. Particularly, increased competition from and offshoring to low‐wage countries seem recently to have had a considerable impact on the creation of skilled jobs and the displacement of less skilled jobs in the tradable sector in Sweden. Furthermore, we apply a similar method as for industries to identify tradable occupations. Using our classification of tradable industries and tradable occupations in a Mincer type wage equation, we find that workers in such industries and occupations receive a wage premia of 12–13 per cent.     

The Performance of Local versus Foreign Mutual Fund Managers

In this paper we examine the performance of US equity funds (locals) versus UK equity funds (foreigners) also investing in the US equity market. Based on informational disadvantages one would expect the UK funds to under‐perform the US funds, especially in the research‐intensive small company market. After controlling for tax treatment, fund objectives, investment style and time‐variation in betas, we do not find evidence for this. In the small company segment we even find a slight out‐performance for UK funds compared to US funds. Finally we observe a home bias in the UK portfolios, which is partly attributable to UK funds investing in cross‐listed stocks in the USA.     

Opportunism,knowledge, and the performance of franchise chains

An important feature of most franchise chains is that they simultaneously use franchised and company‐owned outlets. In this study, I show that the relationship between the resources provided to outlet managers and the financial performance of franchise chains is contingent on their governance structure. Specifically, opportunism and knowledge considerations seem to prevent chains with a large proportion of franchised outlets from fully leveraging resources such as a valuable brand name and tacit business practices. On the other hand, brand name value and business practices tacitness are not directly related to the proportion of franchised outlets in chains. Copyright © 2008 John Wiley & Sons, Ltd.     

The Subdominant Eigenvalue of a Large Stochastic Matrix

Using intuition and computer experimentation, Brady conjectured that the ratio of the subdominant eigenvalue to the dominant eigenvalue of a positive random matrix (with identically and independently distributed entries) converges to zero when the number of the sectors tends to infinity. In this paper, we discuss the deterministic case and, among other things, prove the following version of this conjecture: if each entry of the matrix deviates from 1/n by at most θ/n^1+е, then the modulus of the subdominant root is at most θ/n^е where θ and ε are arbitrary positive real parameters.     

The expansion of intensive marine aquaculture in Turkey: The next‐to‐last commodity frontier?

Aquaculture is one of the fastest growing food‐producing sectors, and its share in global seafood production is rising significantly compared with capture fisheries. This transforms seafood production practices while allowing capital to expand to new marine commodity frontiers. Building on the conceptualization of aquaculture as a new frontier for capture fisheries, the article aims to uncover how commodity frontiers expand within the intensive marine aquaculture sector and shape the transformation of seafood production by focusing on its recent growth in Turkey. It analyses this transformation based on 22 in‐depth interviews with key social actors in Turkey, as well as a review of sector and state reports and the relevant legislations of Turkey and the European Union, and argues that the three‐pronged horizontal, vertical, and taxonomic expansion already observed in industrial capture fisheries has similarly taken place in intensive marine aquaculture through the commodity widening, deepening, and marketing strategies employed by aquaculture firms.     

The tourist experience of domestic VFR travellers: the case of Hungary

Visiting friends and relatives (VFR) is the main driver of domestic travel in many countries. This study is one of the first to analyse VFR travel from a perspective of tourist experience. This study aims to investigate the complex dynamics behind VFR-related travel, especially in aspects of trip activities and tourist experience formation. Based on a survey (N?=?879) examining domestic VFR travellers’ trip activities in Hungary, the paper discusses the formation of a tourist experience in context of short-haul domestic VFR travel, especially the role of influencing factors. The results reveal differences between the segments with trip motivation of visiting friends (VF) and visiting relatives (VR) – the two main types of VFR tourists. It was found that independent variables such as VF, staying for longer and participating in leisure and tourism-type activities have a positive effect on tourist experience evolvement; however, factors such as VR, being rather passive during such a visit and focusing on social acts and bonding negatively affect the formulation of a tourist experience. The paper’s novelty and uniqueness lies in applying a new perspective of analysing and discussing VFR travel: the theoretical concept of tourist experience formation.     

Long-term dynamics of the VIX index and its tradable counterpart VXX

We study the relationship of the VIX index and the exchange-traded note VXX on various timescales. We find that changes of VIX and VXX are correlated only contemporaneously on timescales of days, but VIX leads VXX on timescales of months. Next, we construct a simple joint model for VXX and VIX which replicates all the key characteristics of these two time series, but in which VIX and VXX are related only via a correlated error term. Therefore, VIX cannot be used as a predictor of VXX and there is no apparent trading profit opportunity.     

Green supply chains and the missing link between environmental information and practice

Within the field of green supply chain management (GSCM), an interest in supply chain cooperation to create sustainable competitive advantage, i.e. the collaborative paradigm, has made researchers turn their attention to information related aspects of the supply chain. This study contributes to an understanding of a suboptimal use of environmental information, which is critical for all collaborative efforts aiming at sustainable competitive advantage. The aim of this article is to describe the use of environmental information at different stages of the Swedish food supply chain. The results from this case study of the Swedish food supply chain indicate that environmental information is perceived and used differently by purchasers in the supply chain depending on where (in the supply chain) they are situated in relation to other chain actors. The main contribution of this study is the suggestion of a stage‐dependent connection between perceived environmental cost and perceived environmentally informed consumer demand, which are barriers to GSCM practice discussed in recent GSCM literature. The missing link between information sharing and (environmental) performance of supply chains is explained as distance to end‐consumer in terms of supply chain stages. Implications for GSCM practice and theory are discussed. Copyright © 2009 John Wiley & Sons, Ltd and ERP Environment.
