“…Ours is the first study to examine the optimality of fixed factor endowment in Spanish dairy farms. The results, which point towards a process of intensification through the overexploitation of land, are consistent with the Spanish milk sector dynamics reported by other studies (Álvarez & Del Corral, 2010).…”

“…10 This phenomenon can be captured by considering milk and meat as an aggregate product (Pierani & Rizzi, 2003), as independent products (Stefanou et al, 1992;Cathagne et al, 2006) or excluded altogether (Colman et al, 2005;Álvarez et al, 2006;Álvarez & Del Corral, 2010). 11 Some studies also consider long-run family labour input (e.g.…”

This paper analyses the impact of livestock feed prices and pasture quality on the long and short-term costs of milk production in a region of Spain (Navarre). The empirical results are obtained from the estimation of a flexible shortrun cost function, followed by the approximation of long-run equilibrium based on the quasi-fixed factors adjusted to their optimal levels. The results reveal a high sensitivity of milk production costs to changes in livestock feed prices due to two reasons. One is that, as milk production expands, it tends to become technologically more intensive. The other is that, in the current structure of dairy farming, land input is suboptimal, particularly in the case of large farms and areas of poor pasture. The results reveal that short-run substitution between feed and livestock is a potential strategy for farms to respond to feed price increases. They also suggest that structural policies designed to strengthen the dairy sector's competitiveness should vary according to agro-climatic conditions. In areas of poor pasture, herd growth might be used as a long-term measure to increase competitiveness through economies of scale; while the alternatives for farms in better-endowed regions also include extensification of dairy production.

“…A variety of information criteria can be utilised to choose the number of classes; one of the most employed is the Bayesian Information Criteria (BIC). The lowest BIC value corresponds to the optimal number of classes (Alvarez & del Corral, 2010;Greene, 2005;Krish-nakumar & Chan-Halbrendt, 2010;Popper, Kroll, & Magidson, 2004;Scarpa, Thiene, & Tempesta, 2007;Schlecht & Spiller, 2012).…”

Food habits. Changes among young Italians in the last 10years

et al. 2013

View full text Add to dashboard Cite

a b s t r a c tThe study aims to identify future trends in food habits by comparing the food choices made in Italy by Generation X in the year 2000 with those of Generation Y in 2009. The analysis was conducted utilising the food expenditures surveyed by the National Statistics Institute on a representative sample of consumers. Segmentation was performed using the Latent Class Clustering in order to identify the principal food patterns and their evolution in the span of a decade. The results point out some trends of homologation in food consumptions that are potentially problematic from the viewpoint of the healthy aspects. An increase is noted among the so-called savers, characterised by a diet with a high energetic density, while a decline is noted among the young ''traditionals'' who stand out for their high consumptions of fruit, vegetables and fish. Out-of-the-home consumptions become established among singles, and there is an increase of easy to prepare and ready to eat products, especially among the young people with children of Northern Italy. These elements raise several issues with regard to social, economic and health implications. Public intervention becomes fundamental to provide information and stimulate markets in orienting producers and consumers towards virtuous models, compatible with the new demands of society.

“…A growing body of literature has emphasised the importance of different technologies in estimating technical efficiency (TE) and technological change (TCH) in the dairy sector (Alvarez-Del Corral, 2010;Alvarez et al, 2012;Emvalomatis, 2007;Sauer-Morrison, 2013). …”

Heterogeneous technology, scale of land use and technical efficiency: The case of Hungarian crop farms

In this paper, we analyse the technical efficiency (TE) of Hungarian crop farms between 2001 and 2009 using conventional stochastic frontier analysis (SFA) and a latent class model (LCM). Our results suggest that technological heterogeneity plays an important role in Hungarian cereal, oilseed and protein (COP) crop producing farms, which are traditionally assumed to use homogeneous technologies. We identify two groups with different technologies using an LCM, and find that the scale of land use is one of the most important factors that differentiates our sample into unique technologies. Our results reveal that in the Hungarian COP sector there is less chance to increase performance through TE improvement than was earlier expected. The estimations also suggest that there is no room to improve productivity by increasing farm size, unless farms switch technologies. Consequently, agricultural policies for increasing productivity should concentrate on technological progress.
