Excess Capital in Agricultural Production AgEcon
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.

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....

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...

FARM HETEROGENEITY IN WILDLIFE PRODUCTION AgEcon
van Wenum, Jaap; Oude Lansink, Alfons G.J.M.; Wossink, Ada.
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...

Methodological and empirical progress and challenges in integrated assessment of agricultural systems and policies AgEcon
van Ittersum, Martin K.; Heckelei, Thomas; Oude Lansink, Alfons G.J.M.; Wolf, Joost; Kanellopoulos, Argyris; Britz, Wolfgang.
In this contribution we first present a methodology for integrated assessment of agricultural systems (SEAMLESS Integrated Framework), illustrate its application in an integrated assessment of high commodity prices and then discuss its flexibility and limitations. From there we take a broader view and reflect on key scientific and empirical questions with respect to the development of research tools for the integrated assessment of agricultural systems.

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....

Farm Level Economic Implications of Genetic Selection for Improving Milk Fat Composition AgEcon
Demeter, Robert Milan; Bovenhuis, Henk; Kristensen, Anders Ringgaard; Oude Lansink, Alfons G.J.M.; Meuwissen, Miranda P.M.; van Arendonk, Johan A.M..
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...

Livestock farmers’ attitude towards manure separation technology as future strategy AgEcon
Gebrezgabher, Solomie A.; Lanker, Dora; Meuwissen, Miranda P.M.; Oude Lansink, Alfons G.J.M..
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...

Measurement of dynamic efficiency, a directional distance function parametric approach AgEcon
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 AgEcon
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 AgEcon
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? 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...

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.

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...

Multi-criteria assessment of ethical aspects in fresh tomato systems: Plant genomics technology innovation and food policy uses AgEcon
Michalopoulos, T.; Oude Lansink, Alfons G.J.M.; Heuvelink, E.; Hogeveen, Henk.
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...

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...

Learning in Organic Farming – An Application on Finnish Dairy Farms AgEcon
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...
