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.     

Testing the Intransitivity Explanation of the Allais Paradox

This paper uses a two-dimensional version of a standard common consequence experiment to test the intransitivity explanation of Allais-paradox-type violations of expected utility theory. We compare the common consequence effect of two choice problems differing only with respect to whether alternatives are statistically correlated or independent. We framed the experiment so that intransitive preferences could explain violating behavior when alternatives are independent, but not when they are correlated. We found the same pattern of violation in the two cases. This is evidence against intransitivity as an explanation of the Allais Paradox. The question whether violations of expected utility are mainly due to intransitivity or to violation of independence is important since it is exactly on this issue the main new decision theories differ.     

Religious and Spiritual Dimensions of the Vietnamese Dementia Caregiving Experience

This paper focuses on the role of religion and spirituality in dementia caregiving among Vietnamese refugee families. In-depth qualitative interviews were conducted with nine Vietnamese caregivers of persons with dementia, then tape-recorded, transcribed, and analyzed for emergent themes. Caregivers related their spirituality/religion to three aspects of caregiving: (1) their own suffering, (2) their motivations for providing care, and (3) their understanding of the nature of the illness. Key terms or idioms were used to articulate spiritual/religious dimensions of the caregivers' experience, which included sacrifice, compassion, karma, blessings, grace and peace of mind. In their narratives, the caregivers often combined multiple strands of different religions and/or spiritualities: Animism, Buddhism, Taoism, Confucianism and Catholicism. Case studies are presented to illustrate the relationship between religion/spirituality and the domains of caregiving. These findings have relevance for psychotherapeutic interventions with ethnically diverse populations.     

R&D in a post centrally-planned economy: The macroeconomic effects in Poland

Half a century of centrally planned policy in the Central and Eastern European countries resulted in outdated technologies, inefficient allocation of resources and low productivity. Following the end of communism there was a fifteen year process of transition which ended in 2004 with eight post-communist countries joining the European Union (EU) of which Poland was the largest. As part of the EU these countries now face the challenge of the common EU strategy Europe 2020, which has set the target of achieving R&D expenditure to GDP ratio (called the R&D intensity) of 3% by 2020 for the Union as a whole in an effort to increase the competitiveness of the region. Poland, like the other post-communist countries, faces a lower target of R&D intensity, set at 1.7%. Nevertheless, the challenge is immense, since the country is still at only half that level and has little experience in developing policies to help achieve it. In this paper we tested two possible policy options to achieve the target: (1) to increase government expenditures on R&D and; (2) to provide tax relief on R&D to businesses. The method applied to assess the options is a recursive dynamic computable general equilibrium (CGE) model for Poland with an explicit link between productivity and R&D stock. The results show that achieving the R&D intensity target via the use of tax relief is 2.5 times more costly to the government budget, but it has a greater impact on the economy in terms of a higher GDP growth. Tax relief proved efficient in the short run while in the long run the government expenditure policy provides better value for money.     

A measure of English acculturation stress and its relationships with psychological and physical health status in a sample of elderly Russian immigrants

This study aims to evaluate the factor structure and criterion validity of the English Language Acculturation Stress (ELAS) scale in a community-based sample of elderly Russian immigrants. The sample consists of 300 Russian immigrants with an equal number of females and males, from 59 to 93 years of age (Mean = 73.26, SD = 7.271). The majority of the respondents were married (72%) at the time the interviews were conducted. On average, the respondents have lived in the U.S. for about 7 years (SD = 3.00). We performed both exploratory and confirmatory factor analyses to ascertain the factor structure or conceptual dimensions of the 11-item ELAS scale. The findings revealed that this 11-item scale encompasses three dimensions: Basic English skills, survival English skills, and social involvement English skills. Correlation analyses of the scale with depression, physical health status, and length of residence suggest that the ELAS has good criterion validity and potential as a screening instrument of language acculturation stress for elderly Russian immigrants. Implications for research and practice are discussed.     

Street‐level discretion,emotional labour and welfare frontline staff at the Australian employment service providers

Despite the current controversial debates about discretion in public bureaucracies in general, and in welfare agencies in particular, the current literature on street‐level bureaucracy mainly assumes that discretion is a distinctive feature of the daily work of public servants. Nonetheless, a pertinent question has not specifically been asked in this literature, that is, given the context of privatisation and increased welfare conditionality in the welfare sector that are seriously challenging welfare frontline staff's commitment to social justice and human rights‐based practices, what are forms of street‐level discretion likely to contribute to improving the quality of welfare services? In this study, we attempt to address this question by exploring discretion displayed by welfare frontline staff in four Australian employment service providers. We argue that emotional labour, especially when being informed by critical empathy, is an important and effective form of street‐level discretion that welfare frontline workers can perform to better support welfare recipients and minimise the punitive aspects of welfare policy.     

Women in waste collection and recycling in Hochiminh City

The generation and management of urban solid waste is an urgent and growing problem in Hochiminh City, as elsewhere in the world. An important contribution to solving the city's waste management problem is made by the recycling industry. The well-organized private system of collection, trade and recycling includes door-to-door itinerant buyers, entirely women, who buy solid waste products from households; a range of small, medium, and big shopkeepers who purchase waste from the buyers; middle-men who link the shopkeepers with the recyclers; and the recycling or production units that transform products for sale to consumers. Earnings of itinerant buyers are low and may be declining. However, their self-employment is critical because they are often the main economic support of their families. Shopkeepers enjoy better standards of living but economic competition and recent environmental regulations threaten the survival of the industry. Policy options are offered for attempting to ensure the survival of recyclers and itinerant buyers, those     

Asymptotic approximations to the gain of the 2shi over stein estimators in linear regression models when the disturbances are small

The paper considers a new family of explicit or fully operational two-stage Stein or hierarchial information (2SHI) estimators for linear regression models, and provides an expression for the difference between the risks of these estimators and the usual Stein-rule estimator when the variance of the disturbance is small. The condition under which the 2SHI estimators have smaller average MSE than the Stein-rule estimator is also given.
