The objective of this paper is to develop a tractable approach for recovering and quantifying all sources of TFP changes (namely, technical change, changes in technical and allocative efficiency, and scale economies) from the econometric estimation of an input distance function which also fully describes the production technology. The proposed theoretical framework relies on Bauer’s TFP decomposition framework and the duality between input distance and cost functions. Hence, instead of using a system approach to estimate a cost frontier, all necessary information for decomposing TFP changes are recovered from its dual counterpart.

Entrepreneurs are embedded in structures from which they attempt to depart. It is to explicate this notion of agency that the authors offer path creation as a concept that lies in contrast to path dependence. Path dependence celebrates the role of chance historical events in shaping the flow of future events. Such a process perspective takes an outsider's view to the genesis of novelty. In contrast, path creators are boundary spanners who disregard myopic pressures from existing relevance structures by making mindful deviations with objects to create new futures. Time is a critical element in this process. Specifically, path creators negotiate the time required for their initiatives to mature and succeed. In doing so, they harness the dynamic efficiencies implicit in adopting a perspective that views the emergence of novelty ex-vizu of a point in time.

Several studies found significant differences between the US American and European management research. Since these studies included only journals published in English language, particularities of German management research are not taken into consideration. In this study a comparative content analysis of all articles in the leading four US American, European (in English language) and German management journals published in 2000 was conducted. The following items were analyzed: research patterns (theoretical versus empirical; and if empirical, nomothetic or idiographic), purpose and data collection methods, and collaborative behavior of authors (international cooperation, national and cooperation within the same university) in the respective geographic areas. On all these variables, clear differences were found.

The objectives of this paper are to examine consumers’ perceptions of Protected Designation of Origin (PDO) beef on the basis of a survey of consumers and buyers of beef.

The paper identifies a profile of PDO beef consumers, examines their behaviour and perceptions on PDO beef, derives the dimensions of perceptions of PDO beef, and establishes segments based upon those dimensions. The results reveal that PDO consumers are representative of all geographical regions, age and profession groups, are lighter consumers of beef and shop for food mainly in the butchers. Consumers’ perceptions on PDO beef emphasises quality, safety, and control. However, underlying those perceptions are six main dimensions and it is possible to identify three segments of PDO beef consumers: a faithful consumer group, an unaware consumer group, and a sensory, price conscious group.

In this paper a study is presented that had as goal to develop a management instrument ( benchmarking)for co-innovation projects on basis of a set of performance indicators for chains and net-works of firms. To base the indicators on a sound basis relevant theories were studied, like industrial economics, resource-based theory, marketing theory, net-work theory and also specialised theories related to flexibility, innovation and quality care.

Thereafter a framework was developed. The framework consist of a quick scan of performance measurement and comparative benchmarking to get a global idea of the possible improvements. For the aspects that need to be improved a more fine tuned approach is the measurement of performance related tot the different processes and a benchmark thereof. In the fine tuned part of the framework we distinguish capacities, realisation and perspectives. The quick scan part is used to get a global idea of the performance of different apple chains in The Netherlands, France and New-Zealand. It appeared to be a useful approach to get an idea about the performance of different chains with help of desk research and published information. Finally, some conclusions are drawn.

In qualitative management research the researcher is sometimes confronted with questions about the use of theory, the value of the empirical findings and the relation between the researcher and his/her informants. This paper presents phenomenography as a research method and describes how the phenomenographic researcher tries to struggle with these dilemmas. At the same time it presents the argumentation for a practical use of the method also in management research.

This paper attempts to analyse Diderot's conception of the actor's skills in relation to the construction of professional competence. In particular, it seeks to give attention to the ways in which mere performance is required in the servicing of a role. When Diderot compares the actor's skill as similar to that of the whore he is making reference to the way in which the nature of the relationship with the other - actor-audience, customer-client - involves putting merely a part of oneself into the role, into the performance, while others aspects of the person are held back. There are many day-to-day references to the experience of work in such terms and the notion of work as "abuse" is not unfamiliar. Here the intention is to analyse the relationship between performance and the emotional repertoire which is used in the service of such performance.

Economic analysis condemns market intervention in favour of farmers as inefficient, if not also ineffective, and therefore well worth reform. Practical experience, however, indicates that such lessons are hard to learn and implement. Part of the reason appears to be that economic analysis seldom clearly identifies the real costs and benefits of reform, and seldom explains these sensibly to the relevant constituencies.

Furthermore, economic analysis rarely explains why the protectionist measures were adopted in the first place, or explores the dependencies that these policies generate. Without these explanations, and without reform strategies that take full account of them, policy reform will continue to be reluctant, slow and frequently counterproductive. This paper reconsiders the evolution of farm policies and the economic assessment of their costs and benefits, and draws conclusions as to the general shape of reforms likely to reconcile economic efficiency with political acceptability. In so doing, it re-phrases conventional economic arguments in terms which seem to accord better with sensible intuition, which may prove more accessible and credible to policy makers and advisors. It concludes with a substantial challenge to the agricultural economics profession.

This paper is concerned with the timing of an agricultural policy reform under uncertainty. The focus is on the opportunity cost of giving up the option to wait when implementing a policy reform. Including the option value in applied policy analysis can help explain why conventional analyses may find observed policies to be Pareto-inferior. Furthermore, it explains why otherwise profitable policy reforms may be delayed. The theoretical model is applied to Norwegian agricultural policy anticipating a prospective WTO agreement. It is argued that the option value should be incorporated into applied policy analysis when high uncertainty prevails.

Agricultural policy reform has been an important source of change in the Chinese agricultural sector. The reforms led to productivity growth and helped China in pursuing its self-sufficiency goal especially in the grain sector. To analyse whether observable productivity growth stems from technologically induced components, or from the market induced parts, a multi-input-multi-output model is derived using an econometric distance function framework. A decomposition allows to distinguish allocative effects, scale effects, technological change, and technical efficiency change. Data on farms in Zhejiang from 1986 to 1999 are used to analyse the impact of policy reform.

Based on the recently completed project on land tenure and the management of land and trees in Asia and Africa (Otsuka and Place 2000), this article attempts to identify the process by which population pressure leads to the individualization of land rights and its consequences on the management of land and trees. A particular focus will be placed on the development of agroforestry systems growing commercial trees, such as cocoa, coffee, cinnamon, and rubber, which are becoming important farming systems in agriculturally marginal areas, where people are particularly poor and natural forests have been degraded rapidly (Otsuka 2000).

The conceptual framework is discussed in the next section, which is followed by the examination of the results of case studies on the management of trees and cropland. Policy implications of this study are discussed in the final section.

In this paper, we conduct an empirical investigation of potential adoption of herbicide-tolerant (HT) genetically modified (GM) rapeseed in France. Our aim is to study ex ante the potential impact of their adoption in France, in terms of adoption level, economic gains, and distribution of these gains between farmers and input suppliers. We use French survey data about current plant protection practices, in order to compute pesticide costs with conventional (i.e., non GM) crops for individual farms. Then, based on results of technical studies about GM variety trials in France, we compute a predicted pesticide cost with the GM variety. Next, we study adoption rates and gains or losses of farmers (adopters and non adopters) and upstream companies (sellers of conventional herbicides, of the total herbicide to which GM rapeseed is tolerant, of GM seed), depending on the GM seed license price, the margin rate on herbicide sales and the price of conventional herbicides.

The paper examines the interlinkages between population pressure and poverty, possible impacts on household welfare and land management, and the consequent pathways of development in a low potential rural economy. A dynamic non-separable bio-economic model, calibrated using data from the Ethiopian highlands, is used to trace key relationships between population pressure, poverty and soil fertility management in smallholder agriculture characterized by high levels of soil degradation. Farm households maximize their discounted utility over the planning horizon. Land, labor and credit markets are imperfect. Hence, production, consumption and investment decisions are jointly determined in each period. The level of soil degradation is endogenous and has feedback effects on the stock and quality of the resource base. This may in turn influence land management choices. Under high population pressure, land becomes dearer relative to labor. This is likely to induce conservation investments, especially when conservation technologies do not take land out of production. When markets are imperfect, poverty in vital assets (e.g., oxen and labor) limits the ability or the willingness to invest in conservation and may lead to a less sustainable pathway. Boserup-type responses are more likely when (privately) profitable technologies exist and market imperfections do not limit farm-households' investment options.

Producers in industrialized countries have been inundated with ideas and information about precision agriculture (PA) and how new site-specific management (SSM) technologies will revolutionize their farm operations. Conjuring up Star Wars-imagery, farmers and their computerized machinery communicate with satellites while speeding up and down the information highway. The farm press has hailed the advent of these technologies as a win-win situation with higher farm profits and improved environmental quality. Certainly the potential is there for greater economic returns and better environmental stewardship. But what exactly is precision agriculture, who is applying it, and where? Is the technology only relevant for developed countries and are there implications for markets? What is the likelihood that environmental benefits will be realized?

This paper addresses these questions by drawing on literature, data, and expert opinion to explore what technologies have been developed and which ones have been or are likely to be adopted, by whom, and where. It considers the environmental implications of this host of new information technologies.

In this paper we report on preliminary results of a research aimed to examine the content of farm animal biodiversity conservation actions currently under implementation in the European Union in the framework of EU Agenda 2000. In particular, we surveyed sixty-three Rural Development Plans (RDPs) set up in twelve countries in application of EEC regulations 1257/99 and 1750/99. Our analysis focused on endangered breeds of six major livestock species included in the RDPs. This analysis, which is based on the comparison with the indicator’s status of the DAD-IS FAO database, allowed to identify priorities in conservation efforts in each country, and estimate the level of expected public expenditure needed to ensure the moving of breeds from at-risk (of extinction) status to not-at-risk status over the period 2000-2006.
