Abstract
This article estimates the efficiency of the 40 retail stores of a prestigious clothing company that operates in the Portuguese fast-fashion retailing market. The study compares the performance among the stores and provides insights into ways of improving performance in the retail clothing industry. A two-stage approach is used in this article. In a first stage, Data Envelopment Analysis (DEA) techniques are used to evaluate the performance of each store and to rank the stores. The input-oriented model was used to assess the summer and winter collections between 2010 and 2013. The results show that the total technical efficiency of the company decreases over time Except for the year 2013, over 90% of the stores show increasing returns to scale during 88% of the period analyzed. The company faces a clear problem of productivity in its retailing operations. This deficiency seems to be intrinsic to the firm as it involves more than 60% of the stores. In a second stage, a quantile regression technique was used. This showed primarily that for the lowest quantiles of the efficiency score conditional distribution the coefficients on experience are very low, even close to zero, which suggests that the efforts taken by the stores in terms of experience are barely recognized by consumers in this fast-fashion retailing chain.

Abstract
This paper analyzes the scientific literature produced recently about new product development (NPD) in order to identify and classify the major fields of knowledge, possible connections, as well as the nature of articles and analytics tools used. A review of the literature was implemented on 461 articles focused on NPD, published in three leading journals between 2000 and 2010. It was possible to create 13 main categories, in which innovation, research and development, NPD products and processes and NPD teams stand out. Results conclude that NPD is multifaceted, includes multiple concepts and interrelated categories. Moreover, future studies need to complement qualitative with quantitative research and to analyze how small and large firms differ.

Abstract
Drawing on the concept of strategic fit, this conceptual paper seeks to clarify the relationship between innovation strategies and supply chain management strategies. This work seeks to propose a conceptual framework to help advance research in this area. A literature review was conducted as a basis for developing a unified framework which best reflects the relationship and fit between the different strategies in each area, something which has been clearly under researched from the strategic fit perspective. The findings can be used to guide the decision making of managers in the areas of innovation and supply chain. Additionally, they can serve as a reference for helping coordinate with other areas of the business, in order to ensure the correct fit between activities and strategies.

Abstract
This paper seeks to analyse how behavioural factors influence the financial decisions of young Mozambican investors. The standard theory of finance assumes investors make rational financial decisions, seeking to minimise risk and maximise their expected utility. However, several studies have been conducted criticizing the assumption that investors are rational, opening the way to behavioural finance theory. According to the behavioural finance approach, financial decisions made by individuals are not based on rational thinking and their risk taking behaviour depends on their beliefs or feelings. Our analysis reveals that young Mozambicans are risk averse towards certain gains and risk lovers when faced with certain losses; they are excessively optimistic about the future; they use the information available as an anchor for their estimates; and they are so overconfident that they believe estimates in uncertain situations to be more accurate than they really are.

Abstract
The objective of this study is to identify, through motivating, inhibiting and facilitating factors, responses to institutional pressures on the relationship between biodiesel plants and family farming cooperatives via the Social Fuel Seal (SFS) in the South region of Brazil. This region is characterized by well-endowed family farming cooperatives. This paper adopts as theoretical lens the institutional theory. It is based on case studies involving qualitative research drawing results from four biodiesel plants with SFS certification and eight family farming cooperatives. The results indicate that the institutional biodiesel framework influenced the SFS-based relationships. This coercion mechanism led the plants to comply with the promotion of family farming via cooperatives. The plants seek legal legitimacy and opt to accept institutional pressures, primarily due to the guaranteed sale of all biodiesel produced via government sponsored auctions. Cooperatives are attracted by the receipt of the social bonus, seen as a prime motivating factor, which can be interpreted as an informal coercive pressure. Considering the context in which the plants and cooperatives are inserted, the SFS promoted changes in the sale of raw materials. It was also found that cooperatives facilitating factors are inversely related with plants inhibiting factors.

Abstract
This study analyses the relationship between ownership concentration and firm value. Our findings, based on a dynamic panel data analysis, show that there is a quadratic relationship between the company's value and its ownership concentration. Additionally, our evidence suggests that for countries where investor protection is low, the relationship follows an inverted 'U' shape, while for countries where investor protection is high, the relationship is positive and nearly linear. Moreover, the influence of blockholders depends on their identity. This paper highlights the superior performance of family firms in controlling agency problems, a situation which contrasts vis-'-vis institutional shareholders. Finally, we report that the family effect is nonlinear. Indeed the positive effect starts to taper off at around 30% of ownership being somewhat smaller and less statistically significant between 30% and 50% of ownership. Moreover, in contrast to recent studies, the family effect is more pronounced in majority-controlled firms. © 2013 Inderscience Enterprises Ltd.
