Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Revoredo-Giha,   Cesar; Lamprinopoulou-Kranis,   Chrysa; Toma,   Luiza; Leat,   Philip M.K.; Kupiec-Teahan,   Beata; Cacciolatti,   Luca.
The recent rise in food prices has increased the concern about the choice of a healthy food basket, especially in the context of the discussion around the formulation of a National Food Policy for Scotland. This concern has brought back the interest in the price and expenditure demand systems as they provide information about consumers’ food decisions. The paper focuses on the consumption of brown and white bread, as they are the most typical ways of cereals use in the UK and nutritionists recommend the consumption of wholemeal or brown bread in contraposition to white bread as part of an appropriate diet due to its health benefits. This paper aims to answer whether changes in bread prices affect the quantity and composition of the Scottish demand for...

Measuring the economic benefits and costs of Bluetongue virus outbreak and control strategies in Scotland
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fofana,   Abdulai; Toma,   Luiza; Moran,   Dominic; Gunn,   George J.; Stott,   Alistair W.
This paper provides an ex-ante economic analysis, comparing six alternative control strategies for the eradication of Bluetongue virus 8 against five incursion scenarios in cattle and sheep populations. The economic analysis assumes a common baseline unavoidable cost of public and private measures that together contribute to prevention of incursion of BTV8 into Scotland. These costs continue over the five year horizon of this analysis regardless of whether a BTV8 epidemic ensues in Scotland and their total present value was found to be approximately £141m over the 5year period. The benefit of this investment is the costs of a BTV8 outbreak avoided; which depends on the time, location and nature of the incursion, on the control strategies adopted to counter...

An analysis of milk quota abolition impact on Scottish farmers’ behaviour
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toma,   Luiza; Barnes,   Andrew Peter; Renwick,   Alan W.
This paper analyses factors influencing Scottish dairy farmers’ intentions to change size of business in response to milk quota abolition. The analysis uses structural equation modelling and is based on survey data collected in 2009 through telephone interviews with 533 farmers. Results suggest that farmers who (1) intend to leave their farm to children; (2) have not inherited their farm from previous generation; (3) perceive a lower impact of milk quota abolition on business; (4) have less negative attitudes towards policies/regulations; and (5) perceived a lower influence of policies/markets on business during the past decade are most likely to increase farm size.

Policy Recommendations for Pursuing a Sustainable Agriculture in a Small Rural Community in Romania
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toma,   Luiza.
The paper gives a range of sustainable agricultural policy recommendations, based on the results of the previous CEESA research phases. We begin by a brief presentation of the Romanian case study dealing with the environmental awareness of farmers, measured by means of agri-environmental indicators and discrete choice modelling. Then, we present the policy instruments dealing with non-point source pollution from agriculture, focusing on those applied in the European Union, that are most likely to be used in accession countries. Here we briefly introduce the Romanian environmental institutional and legislative framework, emphasising the existent water policy instruments. We end up by proposing sustainable agricultural policies that, based on the insights of...

A PARTIAL EQUILIBRIUM MODEL OF THE LINKAGES BETWEEN ANIMAL WELFARE, TRADE AND THE ENVIRONMENT IN SCOTLAND
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toma,   Luiza; Ashworth,   Cheryl J.; Stott,   Alistair W.
This research analyses the impacts of a scientific advance that improves animal welfare, upon the environment and trade in Scotland using partial equilibrium (PE) modelling. The science improves pig neonatal survival through improved (high fibre) sow diets used before mating. Our model simulates the effects of animal welfare changes on the pig production systems (pig meat) and further on trade flows (trade in pig meat) and environment (water and air pollution). We consider two animal welfare simulation scenarios, namely the status quo – no animal welfare change as regards pig neonatal mortality (baseline scenario) and the case of improving pig neonatal survival (alternative scenario) and compare the impacts on trade and environment between the two...

HOW DIFFERENTIATED IS THE SCOTTISH BEEF? AN ANALYSIS OF SUPERMARKET DATA PANEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Revoredo-Giha,   Cesar; Lamprinopoulou-Kranis,   Chrysa; Leat,   Philip M.K.; Kupiec-Teahan,   Beata; Toma,   Luiza; Cacciolatti,   Luca.
The Scottish red meat industry is a major part of the Scottish agricultural economy and is known for producing high quality beef and lamb. Beef and lamb which are produced and processed in Scotland and according to a quality assured production specification, carry the EU ‘Protected Geographical Indications’ (PGI) name of ‘Scotch’. In addition, red meat in Scotland has to compete with high quality imported products (e.g., from Brazil or Argentina) or with meat from elsewhere in the United Kingdom. This paper focuses on the situation of Scotch beef and how differentiated it is in the eyes of consumers. For this purpose we use two years’ retailing data for Scotland (and by socio-economic group) from a major supermarket to estimate the conditional demand for...

A Structural Equation Model of Farmers Operating within Nitrate Vulnerable Zones (NVZ) in Scotland
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toma,   Luiza; Barnes,   Andrew Peter; Willock,   J.; Hall,   Clare.
Structural Equation Modelling (SEM) offers a theoretical basis for developing an understanding of the relationships between attitudes and behaviour. This paper imposes the SEM framework to a compulsory regulation which focuses on reducing diffuse water pollution, namely Nitrate Vulnerable Zones (NVZ). We use a data set collected through a farm survey within NVZs in Scotland in 2007. The model includes six latent variables expressing farmers’ nitrate reducing behaviour, nitrate reducing and profit maximizing behavioural propensities and the underlying determining factors, namely attitude (risk perception) and socio-economic latent variables (access to information and stocking density). The results indicate that the model has an adequate fit to the data and...

Investigation of the factors influencing adoption of GM crops at country level
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hall,   Clare; Toma,   Luiza; Moran,   Dominic.
With the possible exception of nuclear technology, few scientific breakthroughs have generated the level of emotive debate that has surrounded the roll-out of agricultural biotechnology. Initial discussion about the environmental impacts of agricultural genetic modification, are now frequently juxtaposed with counter-claims that the technologies could actually be part of a wider global environmental solution in relation to climate change mitigation and food shortages. This study tests whether there are any consistent messages on why some countries seem to be advancing adoption of the technology, while others are not. We consider the range of claims in existing literature on adoption tendencies and then use structural equation modelling to test and estimate...

Determinants of Romanian Farmers' Participation in Agri-Environmental Programmes
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toma,   Luiza; Mathijs,   Erik.
The paper aims to identify the factors underlying farmers' propensity to participate in agri-environmental programmes in a Romanian rural region that confronts non-point source pollution. For this, we employ structural equation modelling with latent variables using data collected through an agri-environmental farm survey in 2001. The model includes one  'behavioural intention' latent variable ('propensity to participate in agri-environmental programmes') and five 'attitude' and 'socioeconomic' latent variables ('demo-social characteristics', 'economic characteristics', 'agri-environmental information access', 'environmental risk perception' and 'general environmental concern'). The results indicate 'environmental risk perception' as the strongest...

Linkages between Agriculture, Trade and the Environment in the Context of the European Union Accession
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toma,   Luiza; Mathijs,   Erik; Revoredo-Giha,   Cesar.
This paper analyses the impact of trade on environment in Romania using a partial equilibrium model of bilateral trade in beef between Romania and the EU. We use a recursive dynamic model to analyse beef production and trade and adjust it as to include a component to evaluate the impact of liberalised trade due to Romania’s accession to the EU on groundwater and air quality. The environmental module of the model associates the pollution to the use of production inputs. We link the use of itrogen inputs (e.g., nitrogenous fertilisers, manure) to nitrogen loss through leaching/runoff into groundwater (nitrates) and greenhouse gases (emissions of nitrous oxide and methane). We compute the nitrogen loss through leaching/runoff into the groundwater based on the...

Autores: Toma,   Luiza; Sutherland,   Lee-Ann; Barnes,   Andrew Peter; Renwick,   Alan W.; McCrum,   Gillian; Blackstock,   Kirsty.
The paper analyses the land use behaviour of Scottish land managers and the factors influencing it in the current context of the EU rural land use policies. The analysis employs a frequently used behavioural economics method, namely structural equation modelling (SEM). Central to the empirical analysis in this paper is a cross-section database containing data collected in May to June 2009 through telephone interviews of 600 land managers in Scotland. The model tests and estimates the relationships between land use behaviour, i.e., behavioural intentions to change the size of business/holding, and several of its a priori determinants found significant in the scientific literature. The results indicate that a stronger propensity to change size of their...

A Structural Equation Model of the Factors Influencing British Consumers’ Behaviour towards Animal Welfare
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toma,   Luiza; McVittie,   Alistair; Hubbard,   Carmen; Stott,   Alistair W.
Results of national and pan-European consumer surveys and the growth in the demand for so-called “animal friendly” food products suggest that consumers within the European Union show a high level of concern for the welfare of farm animals. This paper analyses the determinants of British consumers’ behaviour towards animal welfare using structural equation models (SEM) with observed and latent variables. SEM is a statistical technique for testing and estimating relationships amongst variables, using a combination of statistical data and qualitative causal assumptions. We used a data set collected in 2005 through face-to-face interviews of 654 consumers in England. We analysed the range of statements in existing literature on consumers’ behaviour towards...
