The role of information sources and image on the intention to visit a medical tourism destination: a cross-cultural analysis

This paper intends to analyze: 1) how information sources, eWOM, and image influence the intention to visit a medical tourism destination;2) the moderating role of culture and 3) cross-cultural differences based on Hofstede’s individualism and uncertainty avoidance. A total of 534 responses were collected using a panel of internet users from six different countries and data were analyzed using structural equation modeling and a series of t-tests. The results show that information sources influence cognitive impressions and in conjunction with overall image and medical cognitive image influence the intention to visit a medical tourism destination. Furthermore, individualism and uncertainty avoidance have a moderating effect among these variables and cross-cultural differences exist in the degree of importance given to information sources, eWOM, image perceptions, and intention.     

Mercosur: fostering regional economic integration

Emerging multinationals are a relatively new phenomena in the global trade scene. Brazilian companies involved in international business, numbering over 900, are present in a number of industries in several markets around the world. The development of Mercosur has created an environment conducive to the increasing involvement of Brazilian companies in overseas markets. This article discusses the relationship among economic integration, flows of foreign direct investment, and firm strategies in the Mercosur region, with respect to the Brazilian experience. ©1998 John Wiley & Sons, Inc.     

WAGE DIFFERENTIALS AND EMPLOYMENT IN A TWO-SECTOR MODEL WITH A DUAL LABOUR MARKET

The concept of a dual labour market is analysed in a two-sector general equilibrium model. The primary sector pays efficiency wages, while there is no connection between efficiency and the relative wage level in the secondary sector. The two sectors produce different goods. Capital is assumed sector-specific. The results under different conditions in the labour market (market clearing, minimum wages and levelling of the wage distribution) are derived analytically. Comparative statics are discussed by applying a linearized version of the model. The outcomes may be used to explain observed differences in wage and employment distributions in the US and Europe.     

Practicing Human Dignity: Ethical Lessons from Commedia dell’Arte and Theater

The paper considers two main cases of how the creative arts can inform a greater appreciation of human dignity. The first case explores a form of theater, Commedia dell’Arte that has deep roots in Italian culture. The second recounts a set of theater exercises done with very minimal direction or self-direction in executive education and MBA courses at the Darden School, University of Virginia, in the United States. In both cases we highlight how the creative arts can be important for promoting human dignity in organizations, and how they can lead to a more authentic conversation about values, ethics, and meaning.     

Persistence,Long Memory,and Unit Roots in Commodity Prices

This article investigates the degree of persistence in several weekly and monthly agricultural prices (corn, soybeans, barrow and gilts, and milk) using long memory (fractional integration) techniques. The results indicate mean reversion (i.e., orders of integration smaller than one) in some of the agricultural prices like corn, milk, and barrow and gilts when the disturbances are autocorrelated. Further, we examine the stability across time in the degree of dependence, and the results indicate that the fractional differencing parameters have not remained constant across time. When we take into account a structural break we find that during the first subsamples, the series are stationary though highly persistent, with orders of integration close to 0 and with large autoregressive coefficients. However, for the periods after the break, the series seem to be nonstationary I(1). Dans le présent article, nous avons étudié le degré de persistance des prix hebdomadaires et mensuels de plusieurs produits agricoles (maïs, soja, castrats et cochettes, lait) à l’aide de tests de mémoire longue (intégration fractionnaire). Nos résultats indiquent une stationnarité (c.‐à.‐d. des ordres d’intégration inférieurs à un) des prix de certains produits agricoles, tels que le maïs, le lait, les castrats et cochettes, lorsque les perturbations sont autocorrélées. Nous avons également étudié la stabilité du degré de dépendance à travers le temps, et nos résultats indiquent que les paramètres de différenciation fractionnaire ne sont pas demeurés constants. Lorsque nous avons tenu compte d’une rupture structurelle, nous avons trouvé que dans les premiers sous‐échantillons, les séries étaient stationnaires quoique très persistantes, avec des ordres d’intégration près de 0 et d’importants coefficients d’autorégression. Dans le cas des périodes suivant la rupture, les séries semblaient non stationnaires I(1).     

Genetically Modified Crops, Corporate Pricing Strategies, and Farmers' Adoption: The Case of Bt Cotton in Argentina

This article analyzes adoption and impacts of Bt cotton in Argentina against the background of monopoly pricing. Based on survey data, it is shown that the technology significantly reduces insecticide applications and increases yields; however, these advantages are curbed by the high price charged for genetically modified seeds. Using the contingent valuation method, it is shown that farmers' average willingness to pay is less than half the actual technology price. A lower price would not only increase benefits for growers, but could also multiply company profits, thus, resulting in a Pareto improvement. Implications of the sub-optimal pricing strategy are discussed.     

Human capital and economic growth in Spain, 1850–2000

We investigate human capital accumulation in Spain using income- and education-based alternative approaches. We, then, assess human capital impact on labor productivity growth and discuss the implications of its alternative measures for TFP growth. Trends in human capital are similar with either measure but the skill-premium approach fits better Spanish historical experience. As education is a high income elastic good, human capital growth computed with the education-based approach seems upward biased for the recent past. Human capital provided a positive albeit small contribution to labor productivity growth facilitating technological innovation.     

Understanding consumers’ perceptions of competitive tiers—can perceived risk help?

A review is presented showing the increasing power of multiple grocery retailers from which an argument is developed questioning whether consumers perceive packaged grocery product fields in terms of brands versus own labels versus generics. Consumers’ perceptions of risk are reduced through information search and it is thought that the different search activities between the high and low risk perceivers may explain perceptions of the competitive structure of product fields. For six packaged grocery fields, separately, qualitative research was undertaken to elicit the dimensions consumers use to evaluate competing items. Data was then collected from 829 householders and was subsequently subjected to cluster analysis. Consumers’ perceptions of the competitive structure of product fields differed from marketers’ expectations and brands were always perceived as being distinct from retailer labels. The result did not appear to be influenced by consumers’ perceptions of risk. Reasons for the result are considered, and managerial implications explored.     

A cognitive perspective on managers' perceptions of competition

This paper focuses on the way managers perceive their competitive environment. Within a cognitive perspective it discusses why they might group similar competitors and considers whether they are attentive to all competing firms. The literature on similarity of perceptions between managers is reviewed. Interviews amongst managers in the North Sea off‐shore oil pumps industry revealed that they made sense of competition through a categorization process. None perceived the industry in the objective manner as economists suggest. Different perceptions as to the nature of competitions were found between managers, but more homogeneous perceptions were seen between managers in the same firm than between different firms.     

A No‐Arbitrage Fractional Cointegration Model for Futures and Spot Daily Ranges

The no‐arbitrage relation between futures and spot prices implies an analogous relation between futures and spot daily ranges. The long‐memory features of the range‐based volatility estimators are analyzed, and fractional cointegration is tested in a semi‐parametric framework. In particular, the no‐arbitrage condition is used to derive a long‐run relationship between volatility measures and to justify the use of a fractional vector error correction model (FVECM) to study their dynamic relationship. The out‐of‐sample forecasting superiority of FVECM, with respect to alternative models, is documented. The results highlight the importance of incorporating the long‐run equilibrium in volatilities to obtain better forecasts, given the information content in the volatility of futures prices. © 2011 Wiley Periodicals, Inc.
