Estimation of poverty measures with auxiliary information in sample surveys

The analysis of poverty measures has been receiving increased attention in recent years. This paper contributes to the literature by developing percentile ratio estimators based on the pseudo empirical likelihood method. In practice, variances of poverty measures could be not expressible by simple formulae and consequently other techniques should be used in the variance estimation stage. Assuming percentile ratios, resampling techniques are investigated in this paper. A numerical example based on data from the Spanish Household Panel Survey is taken up to illustrate how suggested procedures can perform better than existing ones. The effect of a model-misspecification on the proposed estimators is also evaluated by using simulated populations.     

The role of information technology in corporate strategy of small and medium enterprises

The crisis of the new economy might have cast doubt on the usefulness of the Internet for business activities. However, it is unquestionable that the possibilities offered by Internet-based technologies in terms of information processing, transfer and collection enable the firm to improve market knowledge and the relationship with clients and suppliers. This work explores, theoretically and empirically, the possibilities offered by the Internet to facilitate the internationalization process of Small and Medium Enterprises (SMEs) as well as to improve the relationship with other firms within the same value chain. Using a wide representative sample of Spanish SMEs, the empirical analysis confirms the benefits of the Internet in both cases.     

Homogeneity tests in meta-analysis: a Monte Carlo comparison of statistical power and Type I error

The statistical power and Type I error rate of several homogeneity tests, usually applied in meta-analysis, are compared using Monte Carlo simulation: (1) The chi-square test applied to standardized mean differences, correlation coefficients, and Fisher's r-to-Z transformations, and (2) S&H-75 (and 90 percent) procedure applied to standardized mean differences and correlation coefficients. Chi-square tests adjusted correctly Type I error rates to the nominal significance level while the S&H procedures showed higher rates; consequently, the S&H procedures presented greater statistical power. In all conditions, the statistical power was very low, particularly when the sample had few studies, small sample sizes, and presented short differences between the parametric effect sizes. Finally, the criteria for selecting homogeneity tests are discussed.     

Corporate Social Responsibility and Family Business in Spain

Despite the economic relevance and distinctiveness of family firms, little attention has been devoted to researching their nature and functioning. Traditionally, family firms have been associated both to positive and negative features in their relationships with the stakeholders. This can be linked to different orientations toward corporate social responsibility. Thus, this research aims to identify the approaches that Spanish family firms maintain about social responsibility, based on the model developed by Quazi and O Brien Journal of Business Ethics 25, 33–51 (2000). An empirical study carried out for 112 Spanish family firms gives support to our initial assumption about these organizations not being a homogeneous group in terms of their orientation towards corporate social responsibility. The differences in perceptions do not seem to be associated to biographical characteristics. These results lead to some relevant academic and practical implications that suggest interesting lines for future research.María de la Cruz Déniz Déniz is professor in the Department of Management at Las Palmas de Gran Canaria University (Spain).

Bank competition in Russia: An examination at different levels of aggregation

We analyze bank competition in Russia at different levels of aggregation. First, we compute a country-level measure of competition and compare it to that for similar-sized economies. Second, we contrast competition across different groups of banks in Russia. Third, we analyze bank competition across Russian regions. We find that banks in Russia are less competitive than those in Brazil, but more so than those in China and India. Large and state-owned banks exert more market power than others. Finally, competition is stronger in regions where there is less bank concentration, greater presence of banks, and greater financial and/or economic development.     

Citizens’ Europe: Crowded out by economic focus

Over the last ten years the European unification project seemed to rely overwhelmingly on progress in economic terms. The most prominent achievements — the Single Market, the harmonisation of market regulation, the euro — were all driven by an economic rationale. However, attempts to rescue Europe from the ongoing financial crisis call for mutual support and solidarity, concepts that can hardly be derived from pure economic reasoning. This leads to an important question that has been too long neglected: what is the political and civic motivation for a united Europe? Besides a great desire to stabilise peace in Europe, the origins of the unification activities also included mutual interest in language, culture, habits and people in neighbouring countries. Has this been abandoned in favour of a purely economic vision? Or are the economic arguments merely the easiest to promote to the European population? What message does this send in times of mistrust in markets and dim economic prospects for the eurozone? Can a political, cultural and civic European spirit still be reinvigorated, and if so, how?     

Non-profit organizations,entrepreneurship, social capital and economic growth

Traditional economic growth literature focuses mainly on the neoclassical approach. According to this view, firms try to maximize their benefits so that there is no place for non-profit organizations (NPOs). However, the activity of NPOs has a higher relevance in society, and it is necessary to analyze its effects on economic growth. These effects are not direct, but occur through other variables that directly promote economic growth, such as entrepreneurship activity and human capital, and through the improvement of education. We engage in an empirical analysis of these issues using data from 11 countries.     

“Do You Use English in Your Daily Life?” Undergraduate Students’ Perceptions of Their Extramural Use of English

The aim of this research is to analyse the students’ perceptions about their extramural use of English, comparing undergraduates studying their degree in English (EMI) with those studying theirs in their native language (non-EMI) within a span of five academic years. Data collected from a Spanish University suggest that the students´s interest and perception of their possibilities of working abroad in English differ. Results also reveal key differences in the use of extramural English and suggest that exposure to reading books or watching English-language films will eventually contribute to the formation of global mindset in students. The trend of the importance of English during a five year span is also considered, for both strands of students. This study makes a contribution in the field of teaching in international business settings for high education institutions.     

A mixed-mode sensitive research on cannabis use and sexual addiction: improving self-reporting by means of indirect questioning techniques

In this article, we describe the methods employed and the results obtained from a mixed-mode “sensitive research” conducted in Spain to estimate certain aspects concerning patterns of cannabis consumption and sexual addiction among university students. Three different data-collection methods are considered and compared: direct questioning, randomized response technique and item sum technique. It is shown that posing direct questions to obtain sensitive data produces significantly lower estimates of the surveyed characteristics than do indirect questioning methods. From the analysis, it emerges that male students seem to be more affected by sex addiction than female students while for cannabis consumption there is no evidence of a predominant gender effect.
