A dynamic dual model under state-contingent production uncertainty AgEcon
Serra, Teresa; Stefanou, Spiro E.; Oude Lansink, Alfons G.J.M..
In this paper we assess how production costs and capital accumulation patterns in agriculture have evolved over time, by paying special attention to the influence of risk. A dynamic state-contingent cost minimization approach is applied to assess production decisions in US agriculture over the last century. Results suggest the relevance of allowing for the stochastic nature of the production function which permits to capture both the differences in the costs of producing under different states of nature, the differences in the evolution of these costs over time, as well as the differential impacts of different states of nature on investment decisions.

A Risk Assessment Model on Pine Wood Nematode in the EU AgEcon
Soliman, T.; Hengeveld, G.M.; Robinet, C.; Mourits, Monique; van der Werf, Wopke; Oude Lansink, Alfons G.J.M..
Pine wood nematode, B. xylophilus poses a serious threat for the European forest industry. This study applies a quantitative risk assessment to analyze the risk of pine wood nematode in the EU, by estimating the reduction expected within forestry stock available for wood supply and its downstream roundwood market. Spatial analysis is used to join information on climate suitability, host distribution, pest spread and value of assets. Economic impacts are presented spatially on a NUTS-2 scale based on partial budgeting technique and for the EU as a whole based on partial equilibrium modeling. Results highlight the Southern regions of Europe as high risk areas with a total impact on available forestry stock of 19,000 M € after 20 years of an outbreak and no...

An empirical model of optimal import phytosanitary inspection AgEcon
Surkov, Ilya V.; Oude Lansink, Alfons G.J.M.; van Kooten, Olaf.
This paper presents an empirical model of optimal budget allocation for import inspection of imported commodities. In this model, the budget constrained inspecting Agency wants to minimize the expected pest costs related to import trade pathways. The model is applied to the problem of budget allocation for inspection of chrysanthemum cuttings imported to the Netherlands. The numerical results imply that under a budget constraint, resources should be first allocated for inspection of pathways with the greatest expected pest costs. Pathways with lower expected pest costs should receive less or no resources. The inspecting Agency has to trade off risks between inspected and non-inspected pathways.

An Examination of the Relationship Between Subsidies on Production and Technical Efficiency in Agriculture: The Case of Cotton Producers in Greece AgEcon
Emvalomatis, Grigorios; Oude Lansink, Alfons G.J.M.; Stefanou, Spiro E..
Subsidies on production have long been criticized for protecting producers from competition, and thus removing an incentive for efficient use of the resources. This study undertakes the examination of the impact of partially decoupled subsidies on the technical efficiency scores of cotton producers in Greece. The results indicate that compensatory area payments reduce the efficiency scores of the producers by diverting resources from products for which the subsidy is based on the area planted to the production of cotton, for which the aid is related to the volume of output.

Analysing Profits and Economic Behaviour of Organic and Conventional Dutch Arable Farms AgEcon
Oude Lansink, Alfons G.J.M.; Jensma, Klaske.
This paper uses a micro-econometric model to analyse differences in variable profits and economic behaviour between organic and conventional arable farms. Insight in factors underlying these differences is essential in designing policy measures that aim at encouraging the transition to a more sustainable farming practice. The framework is applied to a rotating panel of Dutch conventional and organic arable farms over the period 1990-1999. The results show that the, on average larger variable profit of organic farms is mainly associated with the use of land and technological changes. The shadow price of labour suggests over-use of labour on organic arable farms. Demand for pesticides and supply of output are generally more elastic on organic farms....

Analysing Variation in Russian Dairy Farms, 1990-2001 AgEcon
Bezlepkina, Irina V.; Huirne, Ruud B.M.; Oude Lansink, Alfons G.J.M.; Oskam, Arie J..
Russian dairy enterprises underwent dramatic changes during 1990-2001. Not much is known about the position of these enterprises under the new conditions. This study examined a sample group of dairy enterprises in the Moscow region to try to identify similarities and divergences in historical background, performance, managerial and structural characteristics. A unique farm-level data set from 1990-2001 was used. Assessment of historical characteristics revealed that the currently most successful enterprises were those which in pre-reform years had already shown better economic performance. These farms also had, for the period studied, smaller percentages of reduced resources, no severe debt problems, and better overall management.

Analysis of Farm Development in Dutch Agriculture and Horticulture AgEcon
Bremmer, Johan; Oude Lansink, Alfons G.J.M.; Olson, Kent D.; Baltussen, Willy H.M.; Huirne, Ruud B.M..
This paper analysis the effects of farmer characteristics, farm structure and farm performance on farm renewal and farm growth. The data set used in this research consists of panel data from the Dutch Farm Accountancy Data Network of farms specialized in plant production extended with a data from survey among those farms. Probit models were used to determine the likelihood of the changes. Results show that the degree of mechanization increases the probability of farm growth and farm renewal. Family labour input and solvency have a negative impact on farm growth. Farm size is positively correlated with farm renewal. No indications of the influence of the life cycle have been found.

Analyzing the impact of direct subsidies on the performance of the Greek Olive Farms with a non-monotonic efficiency effects model AgEcon
Zhu, Xueqin; Karagiannis, Giannis; Oude Lansink, Alfons G.J.M..
We analyse the impacts of the CAP reforms on technical efficiency of Greek olive farms. We use a production frontier function and a non-monotonic inefficiency effects model which incorporates the influences of exogenous variables on the mean and the variances of farm efficiency. We formulate policy variables (e.g. the direct subsidies) and farm characteristics as explanatory variables in the inefficiency effects model. We use the 1995-2004 FADN data to estimate the production frontier, to derive technical efficiency, and to determine the effects of the explanatory variables. The study shows that the 10-year average technical efficiency of olive farms is 69%. Direct transfers have a negative and monotonic effect on technical efficiency, while the degree of...

Animals’ Health Control Efficiency in Northwest Portugal: A Two-stage DEA Approach AgEcon
Costa, Leonardo; Oude Lansink, Alfons G.J.M.; Silva, Elvira.
A two-stage approach is employed to analyze the efficiency of cooperatives responsible for ruminants’ disease control (OPP) at the farm level in Northwest Portugal. In the first stage, Data Envelopment Analysis (DEA) is used to estimate and decompose input-based overall inefficiency for each OPP. The input-based inefficiency measures are generated using the directional input distance function. In the second stage, the inefficiency estimates are regressed on environmental and organizational factors in order to explain efficiency differentials. Despite substantial environmental differences, the empirical results indicate that most cooperatives can reduce costs by improving scale efficiency and pure technical efficiency.

Assessing Food Safety Concepts on the Dairy Farm: The Case of Chemical Hazards AgEcon
Valeeva, Natasha I.; Meuwissen, Miranda P.M.; Oude Lansink, Alfons G.J.M.; Bergevoet, Ron H.M.; Huirne, Ruud B.M..
Adaptive conjoint analysis was used to elicit farmers' and experts' preferences for attributes of improving food safety with respect to chemical hazards on the dairy farm. Groups of respondents were determined by cluster analysis based on similar farmers' and experts' perceptions of food safety improvement. Results show differences in priority of the more important attributes. However, respondents in all groups valued "identification of treated cows" as one of the most important attributes. The results provide the processing industry and extension service with a better understanding of aspects that may form farmers' perceptions of improving food safety, and thus help to define the message for targeting different farmer groups.

Competitiveness of dairy farms in three countries: the role of CAP subsidies AgEcon
Zhu, Xueqin; Demeter, Robert Milan; Oude Lansink, Alfons G.J.M..
This paper investigates the impact of CAP subsidies on the competitiveness of dairy farms in Germany, the Netherlands, and Sweden. Technical efficiency results show that coupled subsidies have negative impacts in Germany and the Netherlands, but no significant impacts in Sweden. Decoupled subsidies negatively affect technical efficiency in each country and to a larger extent than coupled subsidies. Relative productivity results indicate that Dutch technology leads to the highest output, followed by technologies in Germany and Sweden. Dutch farms can improve their competitiveness by exploring their current production potential. Besides improving efficiency, German and Swedish farms may have options to improve their production technology.

Costs of Producing Biogas at Dairy Farms in The Netherlands AgEcon
Gebrezgabher, Solomie A.; Meuwissen, Miranda P.M.; Oude Lansink, Alfons G.J.M..
By 2020, Dutch dairy chains envisage to be self‐sufficient with regard to energy used by dairy farms and dairy processors. This would require dairy farms to produce 25 PJ per year, possibly by a combination of wind, solar and biogas. This paper focuses on biogas. To evaluate the project’s viability we estimated the expected technical and financial performance of 4 types of business models, i.e. “CHP‐farm”, “CHP‐large”, “green gas” and “central upgrading of green gas”. Data stem from among others 23 biogas plants in the Netherlands. Anticipating that CHPmodels and green gas models occur with a likelihood of 40% and 60% respectively, the total number of biogas plants would amount to 232 (1% of dairy farms), including a total of 5 million tons of manure per...

Do Farmers Internalise External Impacts of Pesticides in Production? AgEcon
Skevas, Theodoros; Stefanou, Spiro E.; Oude Lansink, Alfons G.J.M..
In modern agriculture, pesticides feature so prominently in growers’ arsenal to reduce crop damage caused by various pests and diseases. But their indiscriminate use can harm human health and the environment and, eventually, impact agricultural productivity negatively. In an era of an increasing public awareness on the external effects of pesticides, the EU is trying to update its pesticide policy by establishing tax and levy schemes. An important question is whether the external impacts of pesticides are also affecting the farmers’ production environment. A damage abatement specification is used consisting of a potential output function and a damage abatement function. The damage abatement function considers both high and low toxicity pesticides, and...

Dynamic adjustments in the Dutch greenhouse sector due to environmental regulations AgEcon
Verreth, Daphne M.I.; Emvalomatis, Grigorios; Bunte, Frank H.J.; Oude Lansink, Alfons G.J.M..
Horticultural firms are dependent on energy to produce, while policy makers focus on reducing the use of energy and investment in energy-saving technologies. The paper aimed to asses Dutch greenhouse farmers‘ responses to policies that would affect prices of different energy inputs. The farmer’s behaviour is modelled in two steps: firms are assumed to maximize profit at given energy use level, and firms are assumed to minimize the discounted sum of energy costs. The model is estimated using farm survey data spanning the period 2001-2008. Short-run and long-run elasticities with respect to prices and investments in energy-using technology are estimated. The greenhouse sector shows a fast adjustment of energy capital towards its long-run equilibrium. This...

Dynamic and static behaviour with respect to energy use and investment of Dutch Greenhouse firms AgEcon
Verreth, Daphne M.I.; Emvalomatis, Grigorios; Bunte, Frank H.J.; Oude Lansink, Alfons G.J.M..
Dutch greenhouse horticultural firms are energy-intensive and major emitters of greenhouse gases. This paper develops a theoretically consistent model that is able to describe the greenhouse firms` behaviour regarding energy use and investments in energy technology. The behaviour of the firm is modelled using a combination of a dynamic cost function and a static profit function framework. This paper derives the optimal quantity of energy and energy capital from the link between these two functions. The model is applied to a panel of 97 Dutch greenhouse firms over the period 2001-2008. The results show that most Dutch greenhouse firms shift from being net electricity users to net electricity producers in the long run. Investing in energy capital contribute...

Dynamic Decomposition of Total Factor Productivity Change in the EU Food, Beverages, and Tobacco Industry: The Effect of R&D AgEcon
Emvalomatis, Grigorios; Stefanou, Spiro E.; Oude Lansink, Alfons G.J.M..
The main objective of this paper is to generate measures of TFP change for the food, beverages, and tobacco industry in the EU. Explicitly taking into account the fact that some of the inputs used in the industry are fixed in the short run, the generated measures of TFP change reflects the dynamic nature of the problem. The second objective is to analyse TFP change into its components and explicitly examine the effect of Research and Development (R&D) effort on TFP growth. Data are collected from EU KLEMS and the OECD Structural Analysis database. The data contain country-level information on output volume, input prices and capital stock, as well as R&D expenditure for the food, beverages, and tobacco industry for the 15 “old” EU Member States....
