Co-creation of tourist experiences: a literature review

This paper reviews the literature concerning co-creation of tourism experiences. It analyses the theoretical underpinnings of co-creation and discusses key dimensions of the concept from the tourist's perspective, highlighting the importance of active participation and interaction. The aim is to propose a psychology-focused definition of on-site co-creation tourism experience on which to base a conceptual framework relating important constructs. Opportunities for future empirical research in this area are suggested.     

Gulf Arab E‐Business Environment: Localization Strategy Insights

The Gulf Arab region, particularly Qatar and the United Arab Emirates (UAE), took significant steps toward adopting e‐business and is poised to become a significant online marketplace. The region has a number of vital ingredients that could make it an e‐commerce powerhouse; however, e‐commerce has not reached its full potential. In this article, the authors explore the e‐business environment in the Gulf Arab region and shed light on some of the opportunities and challenges that are shaping and restricting e‐business infiltration. The article places greater emphasis on the idea of localization and how it may impact consumer behavior and expansion of e‐commerce. We argue that by increasing the focus on culturally customized online content by considering country‐level cultural, geopolitical, and linguistic factors, this region could be lucrative for companies looking to attract online consumers. © 2015 Wiley Periodicals, Inc.     

An existence result for discontinuous games

We introduce a notion of upper semicontinuity, weak upper semicontinuity, and show that it, together with a weak form of payoff security, is enough to guarantee the existence of Nash equilibria in compact, quasiconcave normal form games. We show that our result generalizes the pure strategy existence theorem of Dasgupta and Maskin [P. Dasgupta, E. Maskin, The existence of equilibrium in discontinuous economic games, I: Theory, Rev. Econ. Stud. 53 (1986) 1-26] and that it is neither implied nor does it imply the existence theorems of Baye, Tian, and Zhou [M. Baye, G. Tian, J. Zhou, Characterizations of the existence of equilibria in games with discontinuous and non-quasiconcave payoffs, Rev. Econ. Stud. 60 (1993) 935-948] and Reny [P. Reny, On the existence of pure and mixed strategy equilibria in discontinuous games, Econometrica 67 (1999) 1029-1056]. Furthermore, we show that an equilibrium may fail to exist when, while maintaining weak payoff security, weak upper semicontinuity is weakened to reciprocal upper semicontinuity.     

The Economic Dimension of Quality in Tourism: Perceptions of Portuguese Public Decision Makers at the Local Level

A quality assessment scale in tourism was constructed in five dimensions: economic, development, human resources, marketing and product. We presents the research findings for the economic dimension, aiming to understand the perception of Portuguese public decision makers at the local level. Using survey methodology, a sample of Portuguese municipalities was used for data collection. Exploratory and confirmatory factor analyses were performed, and three factors supported quality assessment regarding economics: development strategy (F1), economic factors of demand (F2), and financial incentives (F3). Results focus on the validation of the psychometric properties of this measuring instrument, identifying key issues for future research.     

Heuristics in Mutual Fund Consumers' Willingness‐to‐Invest: An Experimental Approach

This paper improves the understanding of heuristics in the choice of mutual funds. We analyze the effect of price‐quality relationship and anchors as heuristics on the evaluation of the willingness‐to‐invest. We perform two studies with graduate students who possess a medium–high level of financial literacy in Chile. In the first study, we find that willingness‐to‐invest increases (decreases) when subjects observe (do not observe) in the market a positive relationship between expense ratios (price) and service quality. In the second study, in the presence of an anchor, the reference price obtained by individuals from the market information loses relevance and the anchor effect predominates. Our results confirm that participants, as consumers of financial services, apply heuristics as groundwork for their investment decisions. These heuristics as a decision making process are useful but do not always lead to the choice of the lowest cost alternative with the highest possible service quality.     

Structural change and cumulative causation: A Kaldorian approach

This paper presents a multisectoral model based on Kaldor's approach to explain the importance of structural change and cumulative causation. Divergence in countries' growth rates in Kaldorian models are explained either by different degrees of increasing returns among sectors on the supply side or by different income elasticities of exports and imports on the demand-side, but it is not explained by both factors together. In this vein, a multisector growth model that combines different sectoral income elasticities and different sectoral increasing returns is built to explain how structural changes toward high-tech industries can trigger a process of cumulative causation and ensure higher growth rates in the long run.     

Sociomateriality: Theories,methodology, and practice

This article aims to present the theoretical trends that constitute the notion of sociomateriality in the field of organizational studies and to describe a methodological framework for conducting empirical research in this field. It is a contribution for those interested in understanding and using the sociomateriality approach theoretically and methodologically. The main conclusion is that sociomateriality is a valuable alternative not only for comprehending how the entanglement of human and non-human actors may produce organizations, their practices, and changes, but also for (re)thinking organizational phenomena both ontologically and methodologically.     

A pairs trading strategy based on linear state space models and the Kalman filter

Among many strategies for financial trading, pairs trading has played an important role in practical and academic frameworks. Loosely speaking, it involves a statistical arbitrage tool for identifying and exploiting the inefficiencies of two long-term, related financial assets. When a significant deviation from this equilibrium is observed, a profit might result. In this paper, we propose a pairs trading strategy entirely based on linear state space models designed for modelling the spread formed with a pair of assets. Once an adequate state space model for the spread is estimated, we use the Kalman filter to calculate conditional probabilities that the spread will return to its long-term mean. The strategy is activated upon large values of these conditional probabilities: the spread is bought or sold accordingly. Two applications with real data from the US and Brazilian markets are offered, and even though they probably rely on limited evidence, they already indicate that a very basic portfolio consisting of a sole spread outperforms some of the main market benchmarks.
