Rural livestock asset portfolio in northern Ethiopia: A microeconomic analysis of choice and accumulation AgEcon
Tegebu, Fredu Nega; Mathijs, Erik; Deckers, Jozef A.; Tollens, Eric.
Livestock of different species fulfill different functions. Depending on their livelihood strategies, households differ in their choice of type of animal to keep and accumulation of the chosen animal overtime. This paper investigates the dynamic behavior of rural households’ livestock holding to identify determinants of choice of type of animal households’ keep and accumulation of the chosen animals using a panel data of 385 rural households in a mixed farming system in northern Ethiopia. Dynamic behavior of choice is analyzed for a principal animal, an animal that constitutes the largest value of livestock assets a household possesses, using a multinomial logit model. A household that keeps oxen as a principal animal is considered the reference household....

FARM RESTRUCTURING AND EFFICIENCY IN TRANSITION: EVIDENCE FROM BULGARIA AND HUNGARY AgEcon
Mathijs, Erik; Vranken, Liesbet.
Based on survey data on Bulgarian and Hungarian crop and dairy farms, a double-peaked distribution of technical efficiency is observed. Several factors explain differences in efficiency. Human capital matters not only through age and education, but also through gender as farms with a higher share of women are more efficient. Contracting with upstream processors increased efficiency through facilitating the adoption of technology and the access to credits. The superiority of family farms over corporate farms is confirmed for crops but not for dairy.

THE ALLOCATIVE EFFICIENCY OF LAND RENTAL MARKETS IN TRANSITION AGRICULTURE AgEcon
Vranken, Liesbet; Mathijs, Erik.
This paper examines the functioning of the Hungarian land rental market. The allocative inefficiency of the land rental market is determined by calculating the marginal value productivity of land and using rental prices. Regional differences in allocative inefficiency are then correlated with demographic and socio-economic variables and with labor market-related factors.

Do Management Profiles Matter? An Analysis of Belgian Dairy Farmers AgEcon
Vandermersch, Mieke; Mathijs, Erik.
To assess the performance of a farmer and to identify best practice among a group of farmers, the assumption is often made that all farmers maximize profits and thus share the same business goals. However, performance differs due to personal characteristics, objectives and strategies. A survey carried out among 73 Belgian dairy farmers revealed that for only 34% of the farmers "profit maximization" is a primary objective. A regression analysis revealed that self-declared profit maximizers only obtained a higher farm income per liter, not per labour unit. Through cluster analysis, four main groups of farmers were found with similar objectives and management ideas: (A) risk-taking and progressive cow farmers, (B) riskaverse and progressive labour savers, (C)...

Are EU spatial ex ante coexistence regulations proportional? AgEcon
Demont, Matty; Daems, W.; Dillen, Koen; Mathijs, Erik; Sausse, C.; Tollens, Eric.
The EU is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all member states. While it stresses that any approach needs to be “proportionate to the aim of achieving coexistence”, very few studies have actually attempted to assess whether the proposed spatial ex ante coexistence regulations (SEACERs) satisfy this proportionality condition. In this article, we define proportionality as a functional relationship which is weakly increasing in the incentives for coexistence. We propose a spatial framework based on an existing landscape and introduce the new concept of shadow factor as a measure for the opportunity costs induced by SEACERs. This enables comparing the proportionality of (i) rigid...

Sustainable food versus health concerns AgEcon
Avermaete, T.; Mathijs, Erik.
Simultaneous with the growing demand for sustainable food, statistics in all EU member states report consumption patterns that are characterized by too much fat, overdoses of sugar and a lack of fruits and vegetables. The streams of literature that investigate the factors influencing sustainable food consumption and healthy food consumption are largely separated. However, the question whether there is a positive relationship between consumer behaviour towards sustainable food and consumer behaviour towards healthy food remains largely unanswered. The purpose of this paper is to examine the relationship between the consumption of different types of sustainable food on the one hand, and healthy food patterns on the other. The study is based on a sample of...

THE ECONOMICS OF AGRICULTURAL DECOLLECTIVIZATION IN EAST CENTRAL EUROPE AND THE FORMER SOVIET UNION AgEcon
Mathijs, Erik; Swinnen, Johan F.M..
The break-up of large-scale agricultural production units into individually operated farms differs considerably across East Central Europe and the Former Soviet Union. Large-scale successor organizations to the former state and collective farms still dominate in Slovakia, Hungary, the Czech Republic, and in most states of the Former Soviet Union. In Albania, Armenia, and Latvia, a massive break-up of the collective farms resulted in a domination of smaller scale individual farms. Also within countries there exist wide variations in the decollectivization process between different regions and agricultural subsectors. We develop an economic model of decollectivization to explain these variations and derive a series of propositions regarding factors...

Social Capital and Farmers' Willingness to Adopt Countryside Stewardship Schemes AgEcon
Mathijs, Erik.
The EU provides farmers with incentives to adopt Countryside Stewardship Schemes (CSS) using subsidies in the framework of the agri-environmental regulation of the EU (2078/92), now included in the more general regulation on rural development In this paper, a case study of 36 farmers in the village of Bierbeek, was carried out to investigate the determinants of the willingness to adopt a scheme involving taking care of arable field margins in particular. Bivariate and multivariate logit analysis confirmed not only the importance of personal, structural and financial factors, but also showed the importance of social capital. Farmers who are more open to both professional and nonprofessional contacts are more likely to adopt a CSS. Hence, government and...

THE ECONOMICS OF AGRICULTURAL DECOLLECTIVIZATION IN CENTRAL AND EASTERN EUROPE AgEcon
Mathijs, Erik; Swinnen, Johan F.M..
The break-up of large-scale agricultural production units into individually operated farms differs considerably across Central and Eastern European countries. Family farming is not well developed in countries where large-scale successor organizations to the former state and collective farms still dominate, such as Slovakia, Hungary and the Czech Republic. However, family farms are important in Albania and Latvia, where a massive break-up of the collective farms resulted in a domination of small-scale production units. Also within countries there exist wide variations in the decollectivization of different regions and agricultural subsectors. We develop an economic model of decollectivization to explain these variations and derive a series of...

Economics of spatial coexistence of genetically modified and conventional crops: Oilseed rape in Central France AgEcon
Demont, Matty; Daems, W.; Dillen, Koen; Mathijs, Erik; Sausse, C.; Tollens, Eric.
Europe is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all EU Member States. We conduct simulations with the software ArcView® on a GIS dataset of a hypothetical case of GM herbicide tolerant oilseed rape cultivation in Central France. Our findings show that rigid coexistence rules, such as large distance requirements, may impose a severe burden on GM crop production in Europe. These rules are not proportional to the farmers’ basic incentives for coexistence and hence not consistent with the objectives of the European Commission. More alarming, we show that in densely planted areas a domino-effect may occur. This effect raises coexistence costs and even adds to the non-proportionality...

Trader-supplier Coordination in the Agrifood Supply Chains in Northern Ethiopia AgEcon
Alemu, Abebe Ejigu; Mathijs, Erik; Maertens, Miet; Deckers, Jozef A.; Gebregziabher, Kidanemariam; Baur, Hans; Gebrehiwot, Kindeya.
There exists a huge agrifood potential in Ethiopia. However, the country's agrifood supply chains are underdeveloped to deliver quality supply to traders and supplement household livelihoods from the sector. The key factors that determine the proper functioning of supplier-trader chains were not rigorously investigated, at least in the case study area. This paper aims at examining the key determinants in choosing vertical coordination for agrifood products in Tigray, Northern Ethiopia. Structured questionnaires were administered to 247 traders in 10 towns in Tigray. Probit model was employed to identify the key determinants of vertical coordination. Model results show that market information, product characteristics, firm characteristics, and product...

Linkages between Agriculture, Trade and the Environment in the Context of the European Union Accession AgEcon
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...

Sustainable Development of the Flemish Greenhouse Industry AgEcon
Verwilt, Poi; Mathijs, Erik.
This paper addresses the sustainable development of the Flemish greenhouse industry by investigating the optimal size, structure and location of its farms. It emphasizes the importance of a square shape of the greenhouse as optimal structure. Using Data Envelopment Analysis an optimal farm size that varies between 1.7 and 3 hectares has been found, depending on the method used. Location factors that matter in the future Flemish greenhouse industry include temperature, light, transportation costs, air pollution and land prices, while rainfall, wind, output price differences, soil and infection risk do not differentiate between regions.

Contingent valuation analysis of rural households’ willingness to pay for frankincense forest conservation AgEcon
Tilahun, Mesfin; Mathijs, Erik; Muys, Bart; Vranken, Liesbet; Deckers, Jozef A.; Gebregziabher, Kidanemariam; Gebrehiwot, Kindeya; Bauer, Hans.
Frankincense from Boswellia papyrifera forest (BPF) is a traded non timber forest product (NTFP) used in pharmaceutical, food, cosmetic and chemical industries. However, the resource in northeastern Africa is under continuous degradation and requires conservation measures. Data from a discrete choice contingent valuation study are used to assess the factors influencing rural households’ willingness to pay (WTP) and willingness to contribute labor (WTCL) for BPF conservation in Ethiopia. The standard probit, bivariate probit and interval data models were used for modeling respondents’ WTP and WTCL. We found household income as the most important factor affecting WTP whereas number of household labor is the most important factor affecting WTCL. Mean lower...

Commercialization and Subsistence in Transaction Agriculture: Empirical Evidence from Albania, Bulgaria, Hungary and Romania AgEcon
Mathijs, Erik; Noev, Nivelin.
Present-day Central and Eastern European agriculture is characterized by a high incidence of small-scale farmers who are not producing for the market. This paper uses household level data from comparative farm surveys in Albania, Bulgaria, Hungary and Romania to analyze which farm household characteristics and endowments influence commercialization and subsistence farming.

Tradable Substitution Rights: Simulation of the Cost-Efficiency of a Nitrogen Reduction in the Pig Finishing Sector AgEcon
Carlier, Peter Jan; Lauwers, Ludwig H.; Mathijs, Erik.
To comply with the European Nitrate Directive, the Flemish manure policy has been elaborated mainly on the base of command and control measures (maximum fertilisation limits etc.). In literature, however, tradable permits are described as a cost efficient and effective instrument. Applied to nutrient emission they might offer an alternative for the current, expensive manure policy. In this publication both policy instruments are compared by means of simulation models. Based on accountacy data from 190 pig finishing farms, it is shown that tradable rights may result in cost savings of over 88%, compared to the most cost efficient command and control model. This result indicates that tradable permits at least need to be considered as a plausible policy...

POST-COMMUNIST AGRICULTURAL TRANSFORMATION AND THE ROLE OF HUMAN CAPITAL: EVIDENCE FROM ROMANIA AgEcon
Rizov, Marian; Mathijs, Erik; Swinnen, Johan F.M..
Farm restructuring in post-communist transition countries has resulted in a broad range of farm types, such as cooperatives, companies, partnerships and sole proprietorships. This study examines which factors affect production organization choices of rural households with an emphasis on the role of human capital in the agricultural transition process. We use a multinomial logit model and data from a nation-wide survey of Romanian farms, organized in 1996. The results of the empirical tests support the main hypothesis that the transformation process outcome depends primarily on human capital and farm physical capital endowments of the household, translated into household income by the household entrepreneurial input. Entrepreneurial ability is...
