Diversity and Communication in Teams: Improving Problem-Solving or Creating Confusion?

Despite the rich and interdisciplinary debate on the role of diversity and communication in group problem-solving, as well as recognition of the interactions between the two topics, they have rarely been treated as a joint research issue. In this paper, we develop a computational approach aimed at modeling problem-solving agents and assess the influence of various levels of diversity and communication in teams on agents’ performance in problem-solving. By communication, we intend a conversation on the persuasiveness of the features characterizing problem-setting. By diversity, we mean differences in how agents build problem representations which allow them to access various solutions. We deploy the concept of diversity along two dimensions: knowledge amplitude, which accounts for the level of available knowledge allowing access to poorer or richer problem representations (compared with complete problem representations), and knowledge variety, which pertains to the differences in the constituents of agents’ representations. We define performance as the frequency with which diverse agents choose the same alternative representation of an agent displaying complete representations of the problem. Our results indicate that communication is more effective when agents elaborate from relatively richer problem representations, as this provides a basis for integrating the variously diverse beliefs of their teammates. Conversely, poorer diverse representations may lead to worse performance when knowledge variety also applies. Lastly, we show that the influence of communication is not monotonically positive, as increasing communication intensity performance may worsen at any level of knowledge availability and knowledge variety.     

The impact of environmental management systems on financial performance in fashion and textiles industries

With rising environmental concerns from consumers and stakeholder groups, environmental management has become an important responsibility for today's fashion and textiles manufacturers. The production of fashion and textiles related products often requires high levels of energy and water consumption, and emits large quantities of pollutants to the environment. Therefore, the adoption of environmental management systems (EMSs) is important and could have a significant impact on these firms' operational performance. This study presents empirical evidence on the performance impact of EMS adoption in the fashion and textiles related industries (FTIs). Although EMSs have emerged as a passport to business in the FTIs, their actual impacts on firms' financial performance have not been explored. We reveal that the adoption of ISO 14000, the most popular EMS, improves manufacturers' profitability in the FTIs over a three-year period as measured by return-on-assets (ROA). Based on our sample, we find that profitability improvement started during the implementation stage and continued at least one year after the firm obtained ISO 14000 certification. We also find that profitability improvement is mainly due to improvement in cost efficiency, measured by return-on-sales (ROS). Specifically, certified firms improved up to 2.9% in ROA and 3.3% in ROS over the three-year period since they implemented ISO 14000. We conclude that there is a positive impact of EMS adoption on firms' financial performance in the FTIs.     

Political competition and policy choices: the evidence from agricultural protection

This article investigates whether political competition plays an important role in determining the level of agricultural protection. In order to do so, we exploit variation in political and economic data from 74 developing and developed countries for the post‐war period. We use two measures of political competition: one that captures the extent to which political power can be freely contested regardless of election results and one based on vote share at last parliamentary elections. Our results, based on static and dynamic panel estimators, show unambiguously that the higher the level of political competitions is, the higher the agricultural protection.     

Nonlinearities in the real exchange rates: new evidence from developed and developing countries

This paper investigates nonlinearities in the dynamics of real exchange rates. We use Monte Carlo simulations to establish the size properties of the Teräsvirta-Anderson test, when the dynamics of the real exchange rate is influenced by an exogenous process. In addition, we show that a modified nonlinearity test, which includes additional right-hand-side variables, performs much better than the original in both Monte Carlo exercises and in the actual data on 1431 bilateral real exchange rate series. Finally, we investigate the dynamics of the real exchange rate for both developed and developing countries using the modified test for the recent floating period. In general, the results find a greater incidence of nonlinear dynamics for developing country real exchange rates.     

Consumer Quality Perception in Traditional Food: Parmigiano Reggiano Cheese

Abstract

The paper aims to classify the quality cues and attributes of grated Parmigiano Reggiano cheese, an Italian traditional food cheese, exploring if they affect consumers’ quality perceptions and expectations. Analysis is based on a questionnaire administered in hypermarkets where grated Parmigiano Reggiano is sold. A factor analysis, using varimax rotation, and a cluster analysis, were performed, using the Stata 12 software package. The clusters used were: geographical origin and packaging (cluster 1); price, brand and quality certification (cluster 2); all sensory attributes (cluster 3); and a combination of sensory attributes with price, brand, and quality certification (cluster 4). This is the first study to examine the quality cues and attributes affecting quality perception and expectations of cheese for grated Parmigiano Reggiano from a consumer perspective. It is also the first to classify cheese attributes following a quality approach, encompassing previously studied sensory and other attributes.     

Food fraud: economic insights into the dark side of incentives

In this review, we contextualise the articles in this special issue, relating them to existing food fraud research, and identify food fraud research trends, challenges and priorities for the near term. We accomplish these aims through a comprehensive review of research by food scientists, economists, other social scientists, legal experts, government research groups and international trade organisations. Existing food fraud research is heavily weighted towards food science, packaging and labelling, and legal areas of knowledge discovery. Moving forward, research is needed pertaining to general economic welfare outcomes from food fraud incidences, economic incentives to deter frauds, economic spillovers from fraud incidences to other food products and markets (domestic and international) and further delineation of the effect of different types of food fraud on consumer and producer welfare. The articles in this special issue make significant contributions to understanding of the role of food fraud in consumer decisions, measuring consumer welfare losses from fraud, food fraud spillover effects to other markets and new frameworks for fraud analysis.     

Expanding the two wings of social capital for value creation: strategic entrepreneurship of HTC, 1997–2008

This study draws on a historical, qualitative case study to explore how a leading Taiwanese high-tech mobile phone manufacturer, HTC, successfully and continuously manoeuvred the two wings of social capital – that is, structural social capital and cognitive social capital – to create value in its strategic entrepreneurial process between 1997 and 2008. Taiwan is a wide-spreading trust-based Chinese Confucian-influenced culture. The process of developing trust-based social capital for value creation consists of three central actions: identifying potential social capital, reinforcing cognitive social capital, and extending structural social capital. Our findings advance knowledge of trust-based social capital based on the perspective of strategic entrepreneurship for value creation and offer practical implications for the mobilisation of social capital. In sum, we suggest that firms could develop trust-based social capital considering business conditions to reduce possible risks or uncertainties of network management in an international arena.     

Are freelancers a breed apart? The role of protean and boundaryless career attitudes in employability and career success

Recent economic and organisational changes have fostered an increasing diversification of the workforce, among whom freelancers are an under‐represented population in the literature. This study aimed at examining the role of protean and boundaryless career, professional commitment, and employability activities in fostering freelancers' subjective career success. Data were collected via an online survey among a sample of 425 Italian freelancers and analysed through structural equation modelling. Results partially confirmed several hypotheses: higher self‐directed career management and boundaryless mindset predicted higher employability activities and professional commitment; moreover, employability and professional commitment acted as mediators between career attitudes and subjective career success. The study provides support for the importance of such variables to freelancers' career success, as well as for the significance of protean and boundaryless careers among nontraditional occupational groups. Interventions aimed at fostering such attitudes could support freelancers in improving their attainment of professional progress and perception of career success.     

Contracting Institutions,Agro‐food Trade and Product Quality

The agro‐food sector has experienced a profound transformation of contractual arrangements along the value chain, coinciding with important technological innovations and product quality upgrading. Our understanding of the impact that this transformation has had on trade flows in the agricultural sector is very limited. In particular, we have limited knowledge about the extent to which the patterns in agro‐food trade have been driven by the quality of contractual institutions. Using existing measures which capture the sensitivity of agro‐food products to contractual imperfections, we show that countries with better contract enforcement specialise in the production of food which requires higher level of relationship‐specific investments. We also find that countries with better contracting institutions and producing contract‐intensive goods specialise in exporting high quality foods. In addition, we show that the quality of contracting institutions might importantly affect the process of product quality upgrading.     

To Be or Not to be Temp? An Analysis of the Moderating Role of Motives for Accepting Temporary Employment

We investigate the role of contract volition and motives for accepting temporary employment in the relationship between precariousness of life and negative psychological symptoms in a sample of 275 Italian temps. Results suggest that the negative effect of contract volition on negative psychological symptoms is partially mediated by precariousness of life. A moderated mediation model shows that specific motives moderate the negative effects of contract volition on precariousness of life, so that when contract volition is higher, workers with weaker motives feel less precarious. This study broadens our understanding of temporary employment outcomes by showing that the negative consequences of precariousness of life seem to be less troublesome among temporary workers with higher contract volition and lower motivation. © 2018 ASAC.
