Costs of Producing Energy in Dutch Dairy Chains 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. Current analyses focus on biogas. To evaluate the project’s feasibility 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”. Data stem among others from 23 biogas plants in the Netherlands. Anticipating that CHP-models and green gas models occur with a likelihood of 40% and 60% respectively, the total number of biogas plants at dairy farms would amount to 463. There would however be an expected deficit of Euro 157 million...

Testing a Performance Measurement Framework for Agri-Food Supply Chains AgEcon
Aramyan, Lusine H.; Oude Lansink, Alfons G.J.M.; van Kooten, Olaf.
Measurement of entire supply chain performance is an important issue, because it allows for "tracking and tracing" of efficacy and efficiency failures and leads to more informed decision-making with regards to chain organization. The ultimate aim of implementing a performance measurement system is to improve the performance of the organization. If supply chains can get their performance measurement right, the data they generate will tell them where they are, how they are doing, and where they are going. The choice of appropriate supply chain performance indicators is rather complicated due to presence of multiple inputs and multiple outputs in the system. This issue becomes even more problematic in the field of food and agribusiness due to specific...

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.

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.

LIQUIDITY AND PRODUCTIVITY IN RUSSIAN AGRICULTURE: FARM-DATA EVIDENCE AgEcon
Bezlepkina, Irina V.; Oude Lansink, Alfons G.J.M..
The Russian agricultural sector has experienced many problems since the beginning of the 1990s that resulted in a fall in farm output. Employing a production function approach and, unlike other studies, farm-level data on more than 20,000 Russian large-scale farms for the period 1995-2000, this study analyzes the impact of both production (land, labour, capital, materials) and financial (debts and budget transfers) determinants on the productivity. Inter-regional differences such as weather conditions and farm-specific features such as geographical location, management and soil quality are taken into account employing the fixed-effect estimation. The findings show that Russian farms operate under liquidity constraints that lower their productivity.

EXPAMOD: A methodological Tool for Linking Farm and Market Models by Means of Econometric Response Functions AgEcon
Perez Dominguez, Ignacio; Bezlepkina, Irina V.; Heckelei, Thomas; Oude Lansink, Alfons G.J.M.; Romstad, Eirik; Kanellopoulos, Argyris.
Technical change at the farm level or changes in input prices often entail that the firm's supply function changes. These changes can take place in numerous ways. This paper presents a methodology that increases the consistency in supply responses across various sets of agricultural products and farm types with a market model based on a statistical response function approach. Since most farm simulation models are limited to a subset of regions and farm types, the linkage to an aggregated model requires a procedure for expanding these results to non sample regions, so that full regional coverage is achieved. This paper addresses theoretical aspects related to the consistency between micro and market level models. Next it deals with some empirical findings...

Semi-Parametric Modeling of Investments in Energy Installations AgEcon
Oude Lansink, Alfons G.J.M.; Pietola, Kyosti.
This paper applies a semi-parametric approach to estimating a generalised model of investments in energy installations. The model accounts for irreversibility and lumpiness of investments by linking a parametric specification of the unobservable dynamic shadow price to observed investment behaviour using a non-parametric specification of the adjustment cost function. The results suggest that marginal costs of investments in energy installations increase quickly at small investment levels, whereas the increase slows down at higher investment levels. Therefore, standard parametric adjustment cost models are likely biased such that they over-estimate small investments and under-estimate large investments.

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.

FARM FIRM MICRO-ECONOMETRIC MODELLING:EMPIRICAL EVIDENCE FROM RUSSIAN DAIRY FARMING AgEcon
Bezlepkina, Irina V.; Oude Lansink, Alfons G.J.M.; Oskam, Arie J..
This study develops a micro econometric model of specialised dairy farms in Moscow Region using panel data over the period 1995-1998. The model is used to analyse the role of input and output subsidies in the on-farm decision making. Theoretical conditions for short term profit maximization and the fixed effect specification are not rejected by the data. Estimates of the parameters related to input and output subsidies are found to be highly significant. The effect of output subsidies on milk output supply is larger then the price effect. Output subsidies are allocated efficiently in the period 1996-1998 and inefficiently in 1995; input subsidies are allocated efficiently in 1995 and inefficiently in 1996-1998.

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.

Technical Efficiency of the Crop Farms under the Various CAP Reforms: Empirical Studies for Germany, the Netherlands and Sweden AgEcon
Zhu, Xueqin; Oude Lansink, Alfons G.J.M..
We analyse the impacts of the CAP reforms on the technical efficiency of the crop farms. We use an output distance function and an inefficiency effects model which incorporates the influences of exogenous variables on farm efficiency. We formulate policy variables (e.g. the CAP subsidies) and producer characteristics as explanatory variables in the inefficiency effects model. We use the 1995- 2004 FADN data to estimate the production frontiers of the crop farms in Germany, Netherlands and Sweden, to derive their technical efficiency, and to determine the effects of the explanatory variables. The study shows that the 10-year average technical efficiency of crop farms is 59% in Germany, 75% in Netherlands, and 70% in Sweden. The average annual technical...

Multivariate Typology of Farm Households Based on Socio-Economic Characteristics Explaining Adoption of New Technology in Rwanda AgEcon
Bidogeza, J.C.; Berentsen, Paul B.M.; De Graaff, J.; Oude Lansink, Alfons G.J.M..
The challenge for agricultural policymakers and planners, particularly in the context of Rwanda with high population density and consequently food insecurity, is how to enable farmers to adopt new technology. It is known that adoption of new technology may vary among farm households because of socio-economic characteristics. This paper intends to typify farm households in Rwanda based on the exploration of factors explaining adoption of new technology. Ultimately, typical farms obtained from the typology will be used, later as basis to develop representative mathematical programming models. Multivariate statistical techniques offer the means of creating such typologies, particularly when an in-depth database is available. This multivariate analysis...

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.
