Ex ante purchasing power parity: An empirical note

Conclusions In the paper, the EAPPP theory was discussed and three different tests with increasingly statistic power were proposed and implemented. The results are mixed, since the theory passed the randomness and orthogonality tests, but not the direct regression test. The impression is that EAPPP seems to hold in a weak sense, since the evidence confirms random movements of real exchange rates and an efficient use of information by agents but not the constraints on (14) postulated by EAPPP. In general, the results of the present study are in accordance with those of Cumby and Obstfeld [1984], Mishkin [1984], MacDonald [1985] and Gaab et al. [1986] who found only weak support to the EAPPP theory. Furthermore, in the case of the dollar-lira exchange rate, our findings are different from those of Tronzano [1987] according to which “although PPP holds very badly in its traditional (absolute or relative formulation), ex ante PPP (both in “weak” and in “strong” version) [is] highly supported by data”. In fact, in our case both the second orthogonality test and the regression test are unfavourable to the EAPPP.     

The impact of employee involvement on organisational commitment and ‘them and us’ attitudes

This article presents a measure of ‘them and us' as a basis for evaluating an employee involvement programme in British Rail. The results of a longitudinal study with control groups and various forms of post-training intervention show no change in organisational commitment but some evidence of a shift towards a more local pattern of identity which excludes union representatives from ‘us'.

Italian consumer awareness of layer hens' welfare standards: a cluster analysis

Animal welfare has assumed in recent years an increasing significance for European consumers, becoming part of the Community Agricultural Policy strategy that encourages farmers to achieve higher standards of animal welfare. Undoubtedly, the superior social sensitivity towards animal welfare has produced over time notable changes within European Union (EU) Policy. However, while EU legislation has progressively focused on granting animals better possibilities to express their behavioural repertoire, recent analysis shows that consumer knowledge of animal welfare compulsory standards is still quite limited. Drawing on the results of a direct survey on 300 Italian food shoppers, our research analyses consumer knowledge of the welfare standards of laying hens. Our findings highlight important market opportunities and policy implications. Our research shows that, although the majority of the sample expressed concern on hen husbandry systems, most of respondents were unaware of the current mandatory labelling system for eggs. Through cluster analysis three segments were found: the inactive consumer cluster, the conflicted consumer cluster and the ethically competent consumer cluster. This segmentation is especially valuable for producers of ‘animal‐friendly’ eggs to identify market opportunities and formulate appropriate marketing strategies.     

Does partnership at work increase trust? An analysis based on the 2004 Workplace Employment Relations Survey

In the late 1990s, partnership at work was embraced with some enthusiasm by a number of stakeholders in employment relations and incorporated in the 1999 Employment Relations Act. The implementation of the Information and Consultation Regulations has also been extensively signalled. We might therefore expect to see some evidence of partnership‐related practices in Britain. The 2004 Workplace Employment Relations Survey (WERS 2004) provides an opportunity to explore the extent of partnership practice, and also, for the first time, to explore its link to trust relations. This article reports evidence from WERS 2004 suggesting that partnership practice remains relatively undeveloped and that it is only weakly related to trust between management and employee representatives and to employees’ trust in management. Direct forms of participation generally have a more positive association with trust than representative forms. There is also modest evidence that trust may be associated with certain workplace outcomes. The case for partnership and more particularly representative partnership as a basis for mutuality and trust is not supported by this evidence.     

A comprehensive view of intelligent transport systems for urban smart mobility

ABSTRACT

Information accuracy and decision-making speed are of paramount importance in managing today’s mobility of goods and people inside the city. Intelligent Transport Systems (ITS) can provide road users with updated information and forecasts on both traffic and weather conditions. The result is a higher efficiency in the use of resources and a better management of physical flows. The purpose of this paper is to conduct an in-depth review on the role of ITS supporting urban Smart Mobility, in order to identify the main gaps in the literature and propose future research streams. In total, 71 papers have been thoroughly analysed: they are mainly focused on technology, with limited attention to value creation. Even though some benefits have been examined, a general lack of quantitative models emerged. Eventually, there is a lack of contributions considering both people and freight transport, even if they are strongly related, especially in an urban environment.
