Economies of scale and gender discrimination in transition: the case of the Republic of Tajikistan

This article tests for economies of scale and for evidence of discrimination based on gender lines in intra-household consumption allocations using data from the Living Standards Survey in the Republic of Tajikistan (TLSS). Overall results support the existence of household economies of scale in Tajikistan; however, empirical evidence supporting boy–girl discrimination is limited despite anecdotal evidence otherwise.     

Innovation in family and non-family SMEs: an exploratory analysis

This study provides an exploratory analysis of differences between family and non-family firms in innovation investment, product and process innovation outcomes, and labor productivity. Using data from the Community Innovation Survey on 2,087 German small- and medium-sized enterprises (SMEs), we observe significant disparities at each stage of the innovation process. Whereas family SMEs have a higher propensity to invest in innovation at all, conditional on investing in innovation, these companies do so less intensively than their non-family counterparts. Family SMEs further tend to outperform non-family SMEs in terms of process innovation outcomes when controlling for innovation investment. Given the level of product and process innovation, however, family SMEs underperform regarding labor productivity in comparison to non-family SMEs. These findings complement previous empirical research by illustrating how the presence of a dominant family relates to innovation inputs and outputs of SMEs in Europe’s largest economy and its innovative SME sector.     

The Prevalence and Risk of Food Insecurity in the Nordic Region: Preliminary Results

Surveys from societies like the USA, Canada, the UK, and France suggest that 5–15% of the population have experienced “food insecurity” in the sense of not having enough food to eat due to a lack of money or other resources. The Nordic countries are among the most affluent societies in the world and it is generally assumed that food insecurity has been eradicated due to relatively low differences in wages and well-developed social security schemes. This representative web survey of food and eating in Denmark, Finland, Norway, and Sweden indicates however that food insecurity does exist in the Nordic region. In line with research from other industrialized counters, it also suggests that women, young people, single parents, and low-income group seem more at risk of experiencing food insecurity than others. These results must be regarded as preliminary, needing to be substantiated by more comprehensive studies. Moreover, there is a need to develop or use more standardized methodologies enabling comparison across countries and mapping trends over time.     

The role of frequent short exams in improving student performance in hybrid global business classes

The authors investigate whether frequent in class exams can improve the performance of students in hybrid global business courses. An experiment was conducted in three hybrid sections of a global business course exposing students to short in class exams. The expectation of a short exam forces students to watch the online lectures and study the course material. By having more prepared students, the professor can devote class time to discussing international business issues. This results in significantly higher student performance. The performance of 182 students was examined and the results show significant improvements for all groups.     

Solomon's Dilemma: An experimental study on dynamic implementation

This paper reports an experimental investigation on two mechanisms for the so-called King Solomon Dilemma, where one of them fails to implement the social choice rule dynamically. We compare the two mechanisms in terms of their welfare, incentive and learning properties.Received: 9 October 2000, Accepted: 13 February 2003, JEL Classification: C70, C78The authors are grateful to José Agulló, Paolo Battigalli, Ted Bergstrom, Ken Binmore, Sandro Brusco, Antonio Cabrales, Francesco Feri, Leo Hurwicz, Raffaele Miniaci, Miguel Angel Meléndez, Juan Mora, Juan D.
