Costs of Producing Energy in Dutch Dairy Chains
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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.

Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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.

Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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.

Autores: 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.

Excess Capital in Agricultural Production
Provedor de dados: 31
Autores: Kumbhakar,   Subal C.; Guan,   Zhengfei; Oude Lansink,   Alfons G.J.M.
In this article we propose a theoretical model for analyzing capital requirement in agricultural production and define excess capital thereupon. We develop a two-step method that allows endogenous regressors in the maximum likelihood estimation. The two-step procedure is also capably of recovering the parameters of time invariant variables in fixed effect models. The model and method are applied to a capital requirement study using data from cash crop farms in the Netherlands. Empirical results show that excess capital widely exists on the farm. The implications of excess capital are further demonstrated with a production frontier analysis.

Autores: 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&amp;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&amp;D expenditure for the food, beverages, and tobacco industry for the 15 “old” EU Member States....

Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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...

The paper discusses the appropriate functional form and estimation technique for a wildlife production function on the farm level. A random effect model was developed to capture the relationship between wildlife output, management practices, natural conditions and non-observed factors that cause a farm specific management bias. Two wildlife measures were compared: species richness and a wildlife yardstick that enables different species to be weighed on their ecological value. The results show that the farm specific factor has a significant impact on the production of wildlife both in terms of species numbers and in terms of ecological values. Parameter estimates that were similar for the species richness specification were found to vary with the yardstick...

Analysing Profits and Economic Behaviour of Organic and Conventional Dutch Arable Farms
Provedor de dados: 31
Autores: 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....

The objective of the study was to assess the farm level economic implications of value-adding genetic selection strategies to improve milk fat composition. Selection based on a quantitative trait (ratio of total saturated to total unsaturated fatty acids in milk) or a known genotype (for the DGAT1 gene) was considered. Technical and economic performance of hypothetical herds were computed by a herd optimization and simulation model. It was assumed that the herds are already bred for the specific milk composition, and the transition period was not considered. Correlated effects of the selection scenarios on milk production, female fertility, and functional longevity traits were accounted for. Results showed that increasing the total unsaturated fatty acids...

In this paper, an ordered probit model is used to assess the factors that affect the probability of livestock farmers having plans to adopt manure separation technology in the future. A survey, based on a postal and computerized questionnaire of representative dairy and pig farms in the Netherlands was carried out in 2009. The results show that age of farmer and a variable which accounts for the interaction between size and location of the farm are important variables explaining the probability of farmers having plans to adopt manure separation technology. Furthermore, farmers who agreed that future application norms are the driving force for considering adoption of manure separation technology were more likely to consider manure separation as the right...

Provedor de dados: 31
Autores: Serra,   Teresa; Stefanou,   Spiro E.; Oude Lansink,   Alfons G.J.M.
This research proposes a parametric estimation of the structural dynamic efficiency measures proposed by Silva and Oude Lansink (2009). Overall, technical and allocative efficiency measurements are derived based on a directional distance function and the duality between this function and the optimal value function. The applicability of the parametric proposal is illustrated by assessing dynamic efficiency ratings for a sample of Dutch dairy farms observed from 1995 to 2005.

Dynamic Efficiency Analysis using a Directional Distance Function
Provedor de dados: 31
Autores: Oude Lansink,   Alfons G.J.M.; Silva,   Elvira.
Input-based dynamic efficiency measures are derived from an adjustment-cost directional distance function approach. A dynamic input directional distance function can be generated from an adjustment-cost technology where the dynamics are explicitly incorporated in the form of the properties of the input requirement sets with respect to the quasi-fixed factors. The properties of the dynamic input directional distance function are inherited from the properties of the technology. The efficiency measures are then applied to a panel data set of Dutch horticulture firms over the period 1991-1995.

Efficiency of Investor Owned Firms and Cooperatives Revisited
Provedor de dados: 31
Autores: Soboh,   Rafat; Oude Lansink,   Alfons G.J.M.; van Dijk,   Gert.
Providing a performance measure of any firm is a crucial issue, not only for the stakeholders of the firm, but also for policy makers, labor unions, and economists. The relevant performance measures should consider the objectives of the firm’s owners. The ownership structure of cooperatives is different from that of investors owned firms, which in principle implies the need of different tools to measure their performance. Typically, however, the performance of cooperatives and investor owned firm is mostly compared using the same approach. In this study, we use Data Envelopment Analysis (DEA) to compare the performance of dairy cooperatives and investor owned firms in major European dairy producing countries using a traditional approach, which views both...

Do Farmers Internalise External Impacts of Pesticides in Production?
Provedor de dados: 31
Autores: 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...

A dynamic dual model under state-contingent production uncertainty
Provedor de dados: 31
Autores: 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.

Analyzing the impact of direct subsidies on the performance of the Greek Olive Farms with a non-monotonic efficiency effects model
Provedor de dados: 31
Autores: 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...

Product assessment for imperceptible characteristics like environmental impact, healthfulness, naturalness, and fairness is a helpful tool in product innovation and for enhancing socially responsible conduct. In this study we apply multiple criteria analysis for the assessment of fresh tomatoes in terms of consumer perceptions regarding the above characteristics. The generated indices provide an explicit and comprehensive representation of consumer perceptions. Existing tomato products from the Dutch market are ranked alongside (reasonable conjectures of) potential products to be developed with the use of plant genomics technology. The results are interpreted to provide insights into the socially optimal use of (plant genomics) technology for fresh tomato...

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...

Learning in Organic Farming – An Application on Finnish Dairy Farms
Provedor de dados: 31
Autores: Sipilainen,   Timo; Oude Lansink,   Alfons G.J.M.
Organic farming technology may be relatively unknown to farmers at the time when they switch from conventional into organic farming. Therefore, experience gained over time and learning by doing may be important determinants in the efficiency of organic farming. It may also take time to reach the optimal nutrient stock of soil and optimal nutrient supply for arable crops under organic farming. Thus, efficiency of organic farming can either grow or decrease over time depending on the nature of the technology and the learning process. This paper estimates technical efficiency of organic farming and its development over time. We control for possible selection bias and regional heterogeneity when estimating a stochastic frontier distance functions for a sample...

Farmers' Exit Decisions and Early Retirement Programs in Finland
Provedor de dados: 31
Autores: Pietola,   Kyosti; Vare,   Minna; Oude Lansink,   Alfons G.J.M.
This paper estimates farmer decisions between three discrete occupational choices: exit and close down the farming operation (1), exit and transfer the farm to a new entrant (2), or continue farming and retain the option to exit later on (3). The farmer optimisation problem is formulated as a recursive optimal stopping problem. The unknown parameters are first estimated by a switching-type, reduced form Probit models and, then by the Simulated maximum likelihood (SML) method, controlling for serial correlation in the errors. Serial correlation in the errors is controlled for by the Geweke-Hajivassiliou-Keane (GHK) simulation technique. The results suggest that the timing and the type of farmer exit decisions respond elastically to farmer characteristics,...

Provedor de dados: 31
Autores: Aramyan,   Lusine H.; Oude Lansink,   Alfons G.J.M.; Verstegen,   Jos A.A.M.
In the Netherlands the greenhouse sector is a major user of energy. It accounts for 7% of the total amount of energy used in the Netherlands and for 79% of the total amount of energy used in agriculture. In order to sustain this sector on the long term, it is important that its use of energy is lowered. One way of reducing energy use for horticultural producers is investing in energy-saving systems. The purpose of this paper is to provide a better understanding of the investment behavior of farm operators. A two-stage econometric model has been applied to analyze the factors influencing the decision of farmers to invest and the level of investments.
