Profiling tourists based on their perceptions of the trustworthiness of different types of peer-to-peer applications

This research profiles tourists based on the extent to which they trust user-generated content (UGC) uploaded in different types of peer-to-peer applications, also considering their socio-demographic characteristics, frequency of travel and motivations for using the Internet and UGC when making their travel choices. For this purpose, latent class segmentation was applied on a sample of 609 Italian tourists and three different clusters were identified, namely: “distrustful tourists”, “untrusted tourists” and “social web tourists”. The findings suggest that hospitality marketers should improve their social media strategy by focusing their attention on Travel 2.0 applications according to the socio-demographic and behavioural characteristics of their target market.     

Incidence,effects, dynamics and routes out of overqualification in Europe: a comprehensive analysis distinguishing by employment status

This study aims to improve our understanding of overqualification by incorporating distinctions in employment status (i.e. self-employed workers, private employees and public employees) in the analysis of the incidence, effects, dynamics and routes out of overqualification. To this end, we apply discrete choice – ordered and nonordered – and count models to the data obtained from the European Community Household Panel for the EU-15. Our results indicate that the incidence of overqualification varies by employment status, where self-employed workers report the lowest occurrence. Furthermore, this analysis suggests that overqualification is a permanent phenomenon and demonstrates that successful pathways out of overqualification differ by employment status. The implications of these results for education and labour market policies are also discussed.     

Trade credit in SMEs: a quantile regression approach

This article analyses the determinants of the trade credit in Spanish manufacturing small and medium-sized enterprises (SMEs) from a new perspective. Specifically, we focus on the relationship between trade credit and other relevance financial resources: bank credit and self-financing. For the first time in the literature, a quantile regression approach is used, which takes into account the heterogeneity of firms in different quantiles of trade credit distribution. Our results show that the relationship between trade credit and other financial sources presents dissimilarities, including differences in sign, on SMEs with different degrees of trade credit. Our findings help to clarify the confusing results achieved in previous research on this topic.     

Identifying the Transition from Efficient-Market to Herding Behavior: Using a Method from Econophysics

We test whether “detrended fluctuation analysis” (DFA)—an econophysics method—identifies the transition from efficient-market trading to herding behavior and the rise of the NASDAQ dot.com stock market bubble. DFA divides a time series into “segments” of varying lengths and then tests whether power-law distributions exist within the segments. A power-law distribution of stock-price changes within a segment indicates herding behavior and the start of the dot.com bubble. The clarity of the transition indication depends on both segment lengths and segment starting dates. Our findings show that DFA can be used to identify the beginning of stock-market bubbles but not the beginning of crashes.     

Persistent Doubt: An Examination of Hedge Fund Performance

We examine whether performance persistence is suspicious. Top quintile portfolios formed on the Sharpe ratio, alpha, and information ratio persistently outperform similarly constructed mediocre third quintile portfolios throughout our sample period, but performance is more modest and less persistent when portfolios are formed on the excess manipulation‐proof performance measure (EMPPM). By selecting funds formed on ranking by Sharpe and information ratios, investors also select funds that have persistently doubtful performance according to the doubt ratio. In contrast, portfolios formed on alphas and especially the EMPPM have much less excess and persistent doubt.     

What is going on when nothing is going on? Exploring the role of the consumer in shaping waiting situations

Research on waiting in services focuses mainly on the role of companies in waiting situations. Much of the existing research envisages the consumer as a passive victim of the delays caused by companies. This article redresses the imbalance in research on waiting by exploring the role of consumers in waiting situations. A qualitative methodology is used, involving data collection through in‐depth interviews and personal diaries, to facilitate an in‐depth analysis of consumers’ waiting experiences. Additionally, a holistic approach is employed with a view to examining the ‘whole’ waiting experience rather than individual or isolated aspects of waiting. The main finding of the study is that consumers play an active and deliberate role in waiting situations. This is the first study to empirically identify the behaviours and initiatives undertaken by consumers when forced to wait for services. The results suggest that consumers play an active role in organising and reducing the real or perceived waiting time. They actively seek information on the length and causes of the wait. And, on occasions, the consumer may also be the cause of the wait or may even increase the delay by their actions. In contrast to most of the existing research on the topic of waiting, this study adopt a qualitative, in‐depth approach, with a multicultural sample, and a focus on the consumer whose role in waiting has previously been overlooked.     

A framework for strategy formulation in sustainable supply chains: a case study in the electric industry

The aim of a sustainable supply chain is the strategic integration of all social, environmental and economic goals within an organization, through a systematic coordination of key business processes in order to improve the long-term economic performance of a company and its value chain. This paper describes a new methodological approach to support the strategy formulation process in sustainable supply chains. The proposed methodology combines three analytical tools (analytic hierarchical process, fuzzy multi-objective optimization, and clustering methods) within a strategy formulation process, integrating the competitive and corporative strategies with the supply chain strategy on the basis of sustainability. A case study in the Mexican Federal Commission of Electricity Gulf-Center Distribution Division shows the capability of our proposed framework. This company is large and complex enough to encompass the whole issue of the supply chain. Results indicate that our methodology is a valid decision support tool to formulate a set of sustainable supply chain strategies, and it is able to generate a coordinated strategy for the management of a sustainable supply chain.     

In Good Company: When Small and Medium‐Sized Enterprises Acquire Multiplex Knowledge from Key Commercial Partners

This study explores the specific conditions under which key strategic alliances of small and medium‐sized enterprises (SMEs) with commercial partners can become multiplex in knowledge exchange. Using survey data from a sample of 150 Spanish SMEs in the information and communication technology (ICT) industry, we find that trust creates an appropriate context for the concurrent acquisition of technological, market, and managerial knowledge. When the SME and its key commercial partner exhibit significant strategic, technological, and market differences, however, the SME's ability to acquire different types of knowledge diminishes considerably, reducing the positive impact of trust on knowledge multiplexity.     

Are false own-account workers less job satisfied than true ones?

This article compares job satisfaction of true and false own-account workers. The latter group refers to own-account workers who are employed with the same tasks by the same employer for whom they previously worked as employees. To create a valid comparable group, the former workers are defined as paid employees who independently started a new business as own-account workers. Using data drawn from the European Community Household Panel for the EU-15 and controlling for possible self-selection issues, we observe that false own-account workers, compared with true ones, have less job satisfaction in terms of type of work, number of working hours, working times, and working conditions and environment. Our results are consistent with existing policies aimed to combat false self-employment developed by many OECD countries.     

Measuring and Accounting for the Deprivation Gap of Portuguese Immigrants in Luxembourg

This paper examines the relative well‐being of Portuguese immigrants in Luxembourg by looking at indicators of material deprivation. We document material deprivation differences between immigrants and nationals—the “deprivation gap”—and measure the extent to which income differentials (and other sociodemographic differences) explain this gap using a combination of non‐parametric methods and a versatile graphical device. We find a large and significant deprivation gap against Portuguese immigrants, whatever the indicator considered. The extent to which the gap is merely a reflection of differences in income, however, depends on what deprivation items are taken into consideration. Income differences almost fully account for material deprivation differences when the latter is measured using the items included in the official EU social indicator of material deprivation. Inclusion of housing condition indicators mitigates this relationship and we then find compelling evidence that the deprivation gap is not entirely accounted for by income differentials.
