Assessing the Enlargement and Deepening of the European Union

This paper estimates a theoretically‐motivated gravity model to examine the effect of the European Union (EU) on trade and whether the order of entry has affected the trade performance of member countries. Additionally, we analyse the impact of the different phases of EU integration on trade. The results show that both original countries and successive enlargements boost intra‐bloc trade. Moreover, the results suggest that the deepening in the integration process has led to more trade creation among members. Finally, only the latter phase of the European integration process (the single currency) has increased trade with non‐members.     

The Effect of Web-Based Information Availability on Consumers' Processing and Attitudes

Most companies use their websites to promote themselves, their products, and their services; these sites provide ever-increasing amounts of information. This paper examines the effects of the amount of information provided on a website on consumers' processing and attitudes. We propose that the amount of information has differential effects on consumers' information processing and attitudes. The influence of need for cognition is also examined. In our study, we create an experimental website with three versions, with each version providing different amounts of information. Results indicate that while information processing diminishes under high levels of information, attitudes remain favorable. In addition, the individual's need for cognition moderates the influence of the amount of information on both consumer information processing and attitudes.     

Population age structure and private consumption in Spain

In this paper we study the effect of population age distribution upon private consumption expenditure in Spain from 1964 to 1997 using aggregate data. We obtain four main results. First, changes in the population pyramid have substantial effects upon the behaviour of private consumption. Second, the pattern of the coefficients of the demographic variables is not consistent with the simplest version of the life cycle hypothesis. Third, we estimate the impact of the demographic transition upon consumption and find positive values associated with episodes in which the shares of groups of individuals with expenditure levels higher (lower) than the mean increased (decreased). Fourth, the results are robust to alternative specifications for the population age distribution.     

The trolley problem: A social constructivist pedagogy approach

The trolley problem has been one of the more widely used thought experiments in business ethics education. However, the approaches used to integrate it in the classroom have not explicitly utilized individual reflection and interpersonal engagement, elements essential for cultivating moral development. Using social constructivist pedagogy, an instructional module integrating the trolley problem into the undergraduate business classroom is presented. The results of an instructional experiment assessing the effectiveness of the module indicate that while the module did not increase moral awareness among students, it had a positive influence on their prosocial intentions. Implications and limitations of the study, as well as directions for future research, are discussed.     

Voting by committees under constraints

We consider social choice problems where a society must choose a subset from a set of objects. Specifically, we characterize the families of strategy-proof voting procedures when not all possible subsets of objects are feasible, and voters’ preferences are separable or additively representable.
