Economies of Scale and the Demand for Food in Switzerland: Parametric and Non‐Parametric Analysis

This paper examines the role of household public goods arising from co‐residence and economies of scale in the allocation of household expenditure. Using both parametric and non‐parametric methods, the paper tests the theoretical prediction that in the presence of shared public goods, larger households should have higher per capita consumption of private goods like food, provided that they do not substitute too much towards the effectively cheaper public good. The results indicate that, at constant per capita total expenditure, the per capita demand for food declines with household size. No evidence is found in favour of the hypothesis that the endogeneity of male and female hours of work in the labour force could be responsible for this anomaly. However, an examination of the role of direct economies of scale in explaining this negative relationship yielded a negative relationship between household size and quality adjusted unit values, suggesting that the effects of direct economies of scale dominate those generated by public goods.

“…Some authors combine foods and nutrients in one index 4,7,9 , while others separate them 6 . Whereas some authors combine indicators of excess intake and of deficient intake in one single index 1,4,6,7,9 , others make separate indices 8 . Finally, indices also differ in the construction of scores.…”

Background: An unbalanced diet is a main risk factor for several chronic diseases. This paper identifies groups of individuals with an unbalanced diet based on the consumption of nutrients. A characterisation of the groups may help to focus efforts aimed at improving the dietary behaviour of the population. Methods: Using nutritional data of 1763 men and 2267 women participating in the German Nutrition Survey of 1998, we constructed two indices for diet quality that each combines a large amount of nutrients into a single indicator. The impact of sociodemographic and lifestyle characteristics on the diet quality indices was analysed using multiple regression analyses. Results: The results show a considerable variation of diet quality between different groups of individuals. High diet quality in terms of the consumption of vitamins, minerals and trace elements is positively associated with income, education level, age, energy intake, food diversity, sport activity and vegetarianism. On the other hand, a low diet quality as indicated by high intakes of e.g. fat, sugar, alcohol and sodium can be expected when energy intake is high, for individuals of middle age and for pregnant and breast-feeding women. Conclusion:The results of this study help to identify groups of individuals with preferable and non-preferable diet quality. For developing public health strategies, in particular the impact of age on diet quality seems to be interesting. The rising diet quality with increasing age could reflect a changing health consciousness. It could thus be a challenge for health policy to promote a healthy way of living focused especially on young individuals.

“…For the demand parameters, the main standard assumption indicates that demand for food products is quite inelastic at the aggregate level of market demand functions (Durhamand and Eales, 2006; Herrmann and Roeder, 1998). You et al (1996, 1998) calculated price elasticities for tomatoes and cucumbers in the United States, suggesting absolute values of about 0.3 and 0.4.…”

Seasonal protection of F&V imports in the EU: impacts of the entry price system

The measures of border protection applied by the European Union (EU) to imports of fruits and vegetables (FV) are complex and usually not well represented in trade models, not only because of the range of instruments still constraining trade, but also because of product differentiation and seasonality in these products. This article assesses the impact of eliminating entry price (EP) constraints applied to a group of FV products. The proposed model is of a partial equilibrium nature and takes seasonality into account. We have applied the model to imports of tomatoes, cucumbers, clementines, and table grapes. Trade impacts of eliminating EP are significant for particular origins, during specific seasons, most notably for Moroccan tomatoes. The volumes and prices of products originating in the EU experience moderate reductions. Copyright (c) 2010 International Association of Agricultural Economists.
