An economic analysis of nanofood labeling

The paper examines the economic effects of labeling food nanotechnology products using an analytical framework of heterogeneous consumers and imperfectly competitive suppliers. Labeling results in increased costs for nanofood producers (the cost effect of the labeling policy), reduced consumer uncertainty regarding the nature of the food product (certainty effect), and can affect consumer attitudes towards nanofoods by being perceived as a warning signal (stigma effect). In this context, nanofood labeling can change the perceived quality differences between nanofoods and their conventional and organic counterparts, with such changes being more salient when the stigma effect is large, when consumers have low awareness of food nanotechnology in the absence of labeling, and/or when competition among nanofood suppliers is more intense. Despite its empirical relevance, the impact of a labeling policy on consumer preferences (and the economic ramifications of such impact) has largely been ignored by the theoretical literature on the economics of labels. Our analysis shows that it matters. Specifically, our study shows that the market and welfare effects of labeling are case-specific and dependent on consumer awareness of, and attitudes towards food nanotechnology before and after the introduction of the policy as well as the relative magnitude of the cost, certainty and stigma effects of nanofood labeling. Our analytical findings also suggest that the effects of nanofood labels on consumer welfare are asymmetric with certain groups of consumers benefiting even when labeling has a stigma effect on nanofoods.     

Heterogeneous impacts of provincial governance on household welfare in Vietnam

This study investigated the role of provincial governance in the growth of per capita income of Vietnamese households, using a balanced panel data set for the period 2012–2014. Although we found no evidence for the influence of provincial governance when a linear fixed‐effect regression estimator was used, the results from a fixed‐effect quantile regression estimator revealed that provincial governance has a positive effect on all groups (but not the poorest) and that the effect tends to be greater for better‐off households. In addition, we found that wage employment plays a larger role in the income growth of poorer households, whereas returns on education are greater for richer households. The findings suggest that a mean regression approach that looks only a t the role of explanatory variables on mean household welfare, and does not consider differences in the distribution of household welfare, may miss some heterogeneity that is of interest to policymakers. Key Practitioner Message: ? Using a quantile regression approach has allowed the current study to provide new insight into the role of household‐related factors in household welfare. ? Finding shows that good governance tends to provide greater benefits to richer households than to other groups in the population.     

Mediating transnational spaces: international students and intercultural responsibility

Despite the significant body of literature on international students’ intercultural development, the core issue of how they see their own responsibility in transnational intercultural spaces is largely neglected. This paper addresses this paucity by examining the intercultural responsibility perceived by international students. It is based on a four-year study that includes interviews with 105 international students and fieldwork in vocational education institutions. It draws on positioning theory and three key concepts: intercultural competence, intercultural capital and national attachment to interpret the nature of international students’ intercultural responsibility. The research underscores four main forms of intercultural responsibility perceived by international students: responsibility to represent the home country, responsibility to respect the host country, responsibility to assimilate into the host culture and responsibility to integrate into the host culture. Intercultural responsibility can emerge from international students’ national attachment and be embedded in their intrinsic commitment and imagination of their role in representing their home country in a transnational space. Intercultural responsibility can also manifest in international students’ self-determined responsibility to respect, accommodate or integrate into the host culture. However, the finding shows that international students’ act of positioning at the periphery of the host community and their perceived responsibility to assimilate into the host culture precludes their capacity to engage in and negotiate reciprocal and respectful intercultural interactions. The study highlights the role of international students’ self-positioning between and across home and host cultures in underpinning their perceived responsibility in transnational spaces.     

The globalization of production,national labour regulations and income inequality in the global North and South, 1980–2013

A central concern over global value chains (GVCs) is whether the integration of national firms into GVCs exacerbates income inequality within countries. However, despite decades of research, the distributional consequences of GVCs remain unclear in the empirical literature. Drawing on panel data from 96 countries between 1980 and 2013, we examine the effects of GVC integration on market income inequality and whether national labour regulations moderate these effects. We find integration increases inequality in the global North and South. More importantly, we find labour regulations amplify the inequality effects of integration in Southern countries by expanding the size of the informal sector while suppressing these effects in Northern countries by promoting unionization. This suggests institutional power from national labour regulations may enhance the bargaining power of labour in the North through increasing collective resources while disempowering labour in the South through reinforcing labour market segmentation between formal and informal sectors.
