A multitude of indices measure the healthiness of dietary patterns. Because validation results with respect to health outcomes do not sufficiently facilitate the choice of a specific dietary quality index, the decision of which index to use for a particular research objective should be based on other criteria. This review aims to provide guidance on which criteria to focus upon when choosing a dietary index for a specific research question. A review of 57 existing specifications of dietary quality indices was conducted, taking explicitly into account relevant construction criteria explicated in the Organisation for Economic Co-operation and Development handbook on constructing composite indicators. Index construction choices regarding the following criteria were extracted: theoretical framework, indicator selection, normalization and valuation functions, and aggregation methods. Preferable features of dietary indices are discussed, and a summarizing toolbox is provided to help identify indices with the most appropriate construction features for the respective study aim and target region and with regard to the available database. Directions for future efforts in the specification of new diet quality indices are given.

Based on a theoretical model that emphasizes the impact of duration, i.e. of the number of years households spent part-time farming or fulltime farming, respectively, we investigate the shifts between these two states. We also identify socioeconomic factors that determine these shifts. The empirical study is based on discrete time hazard approaches, using micro-level panel data from Zhejiang, Hubei, andYunnan provinces from 1995 to 2002.Estimation results suggest relatively high chances of shifts from full-time to part-time farming and a considerable lower risk for the shift in the opposite direction. Significant negative duration dependence is found for the move from full-time to part-time farming suggesting lock-in effects. In addition, we find that labor market participation decisions are significantly related to several household, farm and village characteristics. In particular, the likelihood of shifts from full-time farming to part-time farming is positively related to the educational level of households' workforce.JEL Classifications: C41, J22, J 24, J43, J62, Q12

Agricultural production is spread all over Turkey and the considerably different climatic and topographical conditions among the provinces lead to highly diversified agricultural production. Therefore, is it reasonable to assume an integrated market all over Turkey? The authors analyze spatial price transmission among 28 Turkish provinces with regard to wheat markets. They apply a bivariate threshold vector error correction model with two symmetric thresholds to account for transaction costs. They find an inner cluster of highly integrated provinces and identify the market size as a driving force of market integration. Furthermore, this study is unique in determining the minimum level of transaction costs. The results suggest that the minimum transaction costs impede full market integration more often on smaller than on larger markets. [EconLit citations: L100; D230; Q110].

The Rural Minimum Living Standard is an important component of social security in rural areas of China, as it provides social assistance to poor rural households. The country's size and large development heterogeneities, however, make the policy's implementation a challenging task. Using quantitative and qualitative data from rural households and administrators in five provinces, we identify the pitfalls of multi-level implementation along with the difficulty of measuring income in rural, underdeveloped areas as key sources of an implementation gap that has led to a considerable degree of misallocation of monetary transfers. Changes in the budgeting process and the distribution method might improve the anti-poverty effect of social assistance without having to carry out additional monitoring.

Purpose The need for a universal rural pension system has been heightened by demographic changes in rural China, including the rapid aging of the nation’s rural population and a dramatic decline in fertility. In response to these changes, China’s Government introduced the New Rural Social Pension Program (NRSPP) in 2009, a voluntary and highly subsidized pension scheme. The purpose of this paper is to assess the participation of rural farmers in the NRSPP. Furthermore, the authors examine whether the NRSPP affects the labor supply of the elderly population in China. Design/methodology/approach This paper uses household-level data from a sample of 2,020 households originating from a survey conducted by the authors in five provinces, 25 counties, and 101 villages in rural China. Using a probit model and conducting correlation analysis, the authors demonstrate the factors affecting the participation and the impact of NRSPP on labor supply of the rural elderly. Findings The results show there are several factors that are correlated with participation, such as specific policy variant in force in the respective household's province, the size of the pension payout from government, the age of sample individuals, and the value of household durable assets. Specifically, different characteristics of NRSPP policy implementation increase participation in China’s social pension program. The results suggest that the introduction of the NRSPP has not affected the labor supply of the rural elderly, in general, although it has reduced participation for the elderly who were in poor health. Originality/value Several previous studies have covered the NRSPP. However, all previous studies were based on case studies or just focused on a small region, and for this reason the results cannot reflect the populations and heterogeneity of rural areas. Therefore, a data set with a large sample size is used in this paper to provide a new perspective to fully understand the participation of NRSPP and its impacts on rural households. This paper will make an update contribution to the literature in the area of pension programs in China.

Most research on consumer attitudes does not consider that attitudes are likely influenced by people with whom we have some relationship even though socioeconomic, psychological and political theories recognize the importance of referent individuals’ opinions in attitude formation. Knowledge on the role of referent individuals’ opinions in attitude formation could improve the understanding of consumer acceptance of foods frequently associated with health or other concerns. This article examines the association of attitudes towards genetically modified (GM) crops and foods between young adults and their referent individuals using data collected in 2016 via surveys from the Czech Republic, Russia and Ukraine. Loglinear models of cell counts in contingency tables reveal a positive association of GM food attitudes between young adults and their referent individuals. This association was stronger in Russia and the Czech Republic than it was in Ukraine and stronger between female young adults and their referent individuals than between males and their referent individuals. Concordance in GM food attitudes with mothers is significantly stronger than concordance with best friends but not significantly different from concordance with fathers.

The work is devoted to the dynamics of labor market participation of Chinese rural households. Based on a theoretical farm household framework the choice between four distinct labor market participation states is empirically analyzed. Using household data over the period 1995–2002 from the province Zhejiang we apply a discrete time hazard approach to analyze households' labor market participation histories. In particular, we investigate the movements between autarky and participation in general and, more specifically, the shifts between part‐time and full‐time farming. Estimation results suggest significant duration dependence, more precisely, a decreasing risk of moving from one state to another with an increasing time a household occupies one of these states. Further, the likelihoods of starting any participation in labor markets and to start part‐time farming are considerably higher than to end participation or to return to full‐time farming. In addition, we find that labor market participation decisions are significantly related to several household and farm characteristics.
