Country size and business cycle volatility: Scale really matters

In a recent study Andrew Rose found that country size does not matter for several economic outcomes [Rose, A.K., 2006. Size really doesn't matter: In search of a national scale effect. J. Japanese Int. Economies 4, 482–507]. However, he did not consider the effect that country size may have on business-cycle volatility. To investigate the empirical relationship between business cycle volatility and country size, we use a panel data set that includes 167 countries from 1960 to 2000. The results suggest very strongly that the relationship between country size and business cycle volatility is negative and statistically significant. This implies that smaller countries are subject to more volatile business cycles than larger countries. This holds both in a simple bivariate model and when we include Rose's control variables and openness. Moreover, the results are robust to different sample periods and several detrending methods. It follows that country size really matters, at least in terms of cyclical fluctuations. J. Japanese Int. Economies 21 (4) (2007) 424–434.

A method for projects seeking to merge technical advancements with potential markets

Abstract
The authors discuss a method for merging the results of technical advancements with potential markets during the formulation phase of innovative product development. The method emphasizes direct contact with end-user organisations by multidisciplinary teams, the selection of champions of innovation as the source of useful and relevant insights, and a multi-stage discipline to produce operational definitions of new product opportunities. For people responsible for managing technical activity, the paper offers guidelines for the planning and implementation of search methods, insight generation and specification of innovative products.

Vertically Integrated North–South Trade and the Redux Model

The paper uses the framework of Obstfeld and Rogoff's Redux model to study the impact of monetary shocks on exchange rate, terms of trade, and welfare in the context of a North–South trade. The authors show that a relative Northern monetary expansion can depreciate or appreciate its currency depending on whether the consumption elasticity of money demand and the degree of monopolistic distortion are low or high enough. This shock has asymmetric effects on welfare in such a way that “beggar‐thyself” or “beggar‐thy‐neighbor” effects always occur.

Factors Related to the Academic Performance of Students in the Statistics Course in Psychology

Many studies have examined the factors that influence academic performance in primary and secondary education as well as at university, with the purpose of enhancing learning at these stages and reducing drop-out rates. It is within this research framework that we want to emphasise the deficient performance of students enrolled on the statistics course in the Faculty of Psychology at the University of Barcelona. Consequently, this paper attempts to determine the factors that affect student performance in this subject by undertaking an analysis of a structural equation model and determining its stability over time. In order to accomplish our objective, we worked with two samples of students enrolled statistics classes. The first group comprised 211 students enrolled in the academic year 2000–2001, while the second comprised 287 students enrolled in the academic year 2001–2002. By administering a questionnaire, we obtained information concerning such variables as demographic data, previous academic record, information related to the subject and the degree of satisfaction with it, and the final mark obtained by the students in the subject. The parameters for each group of students were estimated separately and the goodness of fit of the proposed structural model was assessed. The data analysis showed a good fit with both data bases, but the set of estimated parameters differed in the two academic years under consideration.     

A purposeful approach for implementing preventive measures among European teaching professionals: bullying,deteriorated organizational factors and the mediating role of job dissatisfaction in poor health perception

Abstract

This research aims at examining how workplace bullying, a collection of predominant organizational factors and job dissatisfaction may both directly and indirectly influence the emergence of negative health perception among teaching professionals in occupational settings. The method utilized for testing the research hypotheses is based on Partial Least Squares Structural Equation Modeling (PLS-SEM), which enables the simultaneous assessment of construct measurement and the estimation of hypothesized relationships. A sample population of 2328 European educators has been employed to reach research objectives. Results suggest that negative health perception escalates when there is a direct conditioned correlation between this factor and either bullying or certain working conditions, while indirect effects are unveiled when dissatisfaction is added to the research framework as mediating construct. From a theoretical perspective, this work contributes to human resource management research on the subject of detection and prevention of those underlying organizational constituents that might potentially undermine occupational health. From a utilitarian perspective, the findings of this research encapsulate promising implications not only for teaching professionals but also for educational institutions that pursue the continual improvement of health and performance in their educators through human resource management.
