AN APPLIATION OF THE STOCHASTIC LATENT VARIABLE APPROACH TO THE CORRECTION OF SECTOR LEVEL TFP CALCULATIONS IN THE FACE OF BIASED TECHNOLOGICAL CHANGE AgEcon
Bailey, Alastair; Irz, Xavier T.; Balcombe, Kelvin George.
The measurement of the impact of technical change has received significant attention within the economics literature. One popular method of quantifying this impact of technical change is the use of growth accounting index numbers. However, in a recent article Nelson and Pack (1999) criticise the use of such index numbers in situations where technical change is likely to be biased in favour of one or other inputs. In particular they criticise the common approach of applying observed factor shares as proxies for partial output elasticities to weight the change in quantities which they claim are only valid under Hicks neutrality. Recent advances in the measurement of product and factor biases of technical change developed by Balcombe et al (2000) provide a...

Analysis of Vocational and Residential Preferences of Rural Population: Application of an Experimental Technique to Rural Slovenia AgEcon
Zanni, Alberto M.; Davidova, Sophia; Bailey, Alastair.
This study represents the first application of Choice Experiments to the analysis of the monetary and non-pecuniary determinants of vocational choice and spatial labor supply. It identifies the determinants of individual’s choice of jobs and place of residence, and provides a better understanding of the process of rural labor adjustments in a country in transition, Slovenia. The results indicate that the effect of wages, as the main factor influencing employment choice, is counterbalanced by other determinants affecting working conditions and residence. A considerable degree of immobility in terms of migration and commuting has been revealed. As a result, a rapid urbanisation process is unlikely to happen in the near future, according to individuals’...

Commonalities and Differences in Labour Market Developments and Constraints in Different EU Regions AgEcon
Tocco, Barbara; Davidova, Sophia; Bailey, Alastair.
This paper provides a detailed overview of the differences across EU member states’ labour markets,through the extensive use of descriptive statistics. The objective is two-fold: firstly, it identifies the commonalities and differences in rural labour markets across EU regions and their developments, with special regard to agriculture, and secondly it emphasises the constraints that may hinder the efficient functioning of labour markets. Therefore, the paper starts with a description of the main indicators in the general labour market theory, such as the structure of the population in terms of age and gender distribution, unemployment and activity rates, employment levels, quality of human capital, migration patterns, and so forth. Secondly, we focus on...

CONCEPTUAL FRAMEWORK FOR ANALYSING STRUCTURAL CHANGE IN AGRICULTURE AND RURAL LIVELIHOODS AgEcon
Buchenrieder, Gertrud; Mollers, Judith; Happe, Kathrin; Davidova, Sophia; Fredriksson, Lena; Bailey, Alastair; Kancs, d'Artis; Swinnen, Johan F.M.; Vranken, Liesbet; Hubbard, Carmen; Ward, Neil; Juvancic, Luka; Milczarek, Dominika; Plamen, Mishev.
The Deliverable 2.1 (D2.1) of the SCARLED project provides the conceptual framework for analysing structural change in agriculture and rural livelihoods in the NMS and established Member States of the EU. It concisely summarizes the underlying theories and concepts of the pertinent research issues in SCARLED. SCARLED addresses a topic of wide interest with regard to the identification of past and future key social and agricultural restructuring processes for a living countryside in the NMS. Methodologically, the topic is approached by comparative, structured multi-country farm surveys complemented by an analysis of structural changes in the farm sectors of two selected regions with the agent-based simulation model AgriPoliS, taking special account of...

Environmental efficiency of small farms in selected EU NMS AgEcon
Suta, Cornelia Madalina; Bailey, Alastair; Davidova, Sophia.
The objective of this paper is to investigate the relationship between the environmental efficiency and farm commercialisation in selected EU NMS (Bulgaria, Romania and Poland). Using a cross- section of agricultural households, environmental technical efficiency scores are calculated using hyperbolic distance function approach. The results indicate there is a negative relation between the increase in commercialisation of small farms and the production of negative externalities, like nitrogen surplus.

Key Issues in Agricultural Labour Markets: A Review of Major Studies and Project Reports on Agriculture and Rural Labour Markets AgEcon
Tocco, Barbara; Davidova, Sophia; Bailey, Alastair.
This paper provides a synthesis of the empirical literature on the key issues in agricultural and rural labour markets since the 1960s, drawing mainly upon studies from the United States and the European Union, but also including relevant material from developing countries. The contribution of this meta-analysis lies in its unique structure as it covers the main research questions that have been addressed in the literature and includes the most cited papers from the American Journal of Agricultural Economics, Journal of Agricultural Economics, European Review of Agricultural Economics and Agricultural Economics as well as other reports and EU-funded projects. Each research question is accompanied by a tabular summary that classifies the individual studies...

Multiple Adoption of Pest Management Technologies in UK cereal Farming AgEcon
Fraser, Iain; Sharma, Abhijit; Bailey, Alastair.
In this paper we consider the adoption of pest management technologies by farmers in UK cereal crop systems. While for the majority of UK farmers chemical control of pest outbreaks remains important, there are a range of non-chemical approaches and management practices that can be used to control pest populations. However, few of these alternatives produce levels of control that compare with chemical use in isolation. In this paper we consider the determinants of adoption of different combinations of individual pest management technologies. Based on survey data we first construct sets of pest management technologies before modelling the decision problem as a multiple adoption process to examine variation in the adoption of these technology sets. Our...

Rural livelihoods in the EU new member states: subsistence production versus market integration AgEcon
Fredriksson, Lena; Davidova, Sophia; Bailey, Alastair.
Commercialisation of small farmers, of which many are subsistence farmers producing mainly for own consumption needs, is an important policy objective for the restructuring process of the farm structure in the EU New Member States (NMS). Drawing on primary survey data from five EU NMS, this paper first assesses the importance of subsistence farming in the NMS through the valuation of subsistence production at market prices. Secondly, the paper analyses the differences between subsistence and commercial households. Where previous studies normally classify households as subsistence or commercial based on a pre-defined threshold, the use of latent class regression in this paper represents a way to systematically analyse heterogeneous groups of households in a...

Stochastic biases in technical change in South African agriculture AgEcon
Balcombe, Kelvin George; Bailey, Alastair; Morrison, Jamie; Rapsomanikis, George; Thirtle, Colin G..
This paper examines biased technical change in South African agriculture using a system of share equations with unobserved components. Developing on the work of Lambert and Shonkwiler (1995), this paper generalises previous work by introducing independent unobserved components into each model using a regression-based approach. We find evidence of stochastic technical change, which is itself biased between the four factors of production: machinery, land, labour and fertiliser, and which closely reflects distinct phases of South African agricultural policy and development.

Subsistence and Semi-subsistence Farming in Selected EU New Member States AgEcon
Davidova, Sophia; Fredriksson, Lena; Bailey, Alastair.
Factor and cluster analysis are used to analyse the attitudes and perceptions of agricultural households in five EU New Member States towards farming, commercialisation, and barriers to and drivers for an increased integration in agricultural markets. The contribution of unsold output to the total household income is valued. A stepwise linear regression is employed to detect important variables explaining the degree of agricultural market integration of farm households. The analysis indicates that subsistence farming is of utmost importance for the rural poor, and particularly in Bulgaria and Romania. The proportion of consumption from own production, manual cultivation techniques and distance to an urban centre negatively affect output sales. Rural...

Supply and Demand Side Limitations Affecting the Structure of Agriculture and the Rural Economy AgEcon
Tocco, Barbara; Davidova, Sophia; Bailey, Alastair.
This paper criticises the neo-classical assumptions of perfect factor markets and of complete information, which constitute central elements in labour market theory. Based on a literature review and on economic reports from transition economies, as well as developing countries and more advanced economies, this deliverable focuses on the structural impediments and imperfections that often characterise rural labour markets and that may prevent an efficient allocation of labour. According to empirical studies, transactions costs and rigidities hinder the well-functioning of labour markets and constrain labour adjustments. The paper attempts to classify the various limitations of rural labour markets from both the supply and demand side, although the...

Technology Adoption And Pest Control Strategies Among UK Cereal Farmers: Evidence from Parametric and Nonparametric Count Data Models AgEcon
Sharma, Abhijit; Bailey, Alastair; Fraser, Iain.
This paper examines technology adoption and integrated pest management strategies employed by UK farmers, using both parametric and nonparametric methods. We employ a unique survey data set collected from UK cereal farmers to assess the determinants of technology adoption in relation to pest management. Our preferred model specification is nonparametric which makes use of the recently developed methods of Li and Racine (2007) and Racine and Li (2004). These methods allow us to combine categorical and continuous data and thereby avoid sample splitting and resulting efficiency losses. Our analysis reveals that total area farmed is positively related to the number of technologies adopted, whereas age is negatively related. We also find evidence of...

The Impact of Child Obesity News on Household Food Expenditure in the United Kingdom AgEcon
Silva, Andres; Garcia, Marian; Bailey, Alastair.
The United Kingdom (UK) has one of the highest obesity levels in the world (Mazzocchi et al., 2009). As indicated by the National Health Service (2010), 25% of adults and 17% of children are obese in the UK. This last statistic represents an increase of four points in comparison to 1995. The Government Office for Science (2010) estimated that by 2050, half of the UK population would be obese, with a consequent direct annual cost of £10 billion and an indirect annual cost of £50 billion at today’s prices. This research aims to contribute to the debate on how health-related information impacts household food expenditure and whether this impact varies across income groups and household composition. This study specifically measures the impact of child obesity...
