    There has been a fundamental development in theory and understanding of market, private, collective and public organizations in recent years. This paper incorporates achievements of the interdisciplinary New Institutional and Transaction Costs Economics (combining Economics, Organization, Law, Sociology, Behavioral and Political Sciences) and suggests a framework for assessing the needs and efficiency of economic organizations and public interventions in agriculture. Our new approach includes: study of farm and other agrarian organizations as a governing rather than production structure; assessment of comparative efficiency of alternative market, contract, internal, and hybrid modes of governance; analysis of level of transaction costs and their institutional (distribution and enforcement of de-facto rights between individuals, groups, organizations), behavioral (agents preferences, ability, bounded rationality, tendency for opportunism, risk aversion, trust), dimensional (frequency, uncertainty, assets specificity, and appropriability of transactions), natural, and technological factors; determination of effective horizontal and vertical boundaries of farms and other agrarian organizations; specification of the economic role of government and the needs for public interventions in agrarian sector; assessment of comparative of alternative forms of public involvement in agrarian sector (partnership, regulation, taxation, assistance, provision, in house organization, fundamental property rights modernization). The paper provides new powerful tools for understanding the agrarian organizations and their efficiency, and for improvement of public policies, collective actions, farming and business strategies, and academic analyses in that important sector of social life.market, private and public modes of governance, efficiency of farms and agrarian organizations, agricultural policies, transaction costs, New Institutional Economics

    Exploiting Synergy Between Ontologies and Recommender Systems

    No full text
    Recommender systems learn about user preferences over time, automatically finding things of similar interest. This reduces the burden of creating explicit queries. Recommender systems do, however, suffer from cold-start problems where no initial information is available early on upon which to base recommendations. Semantic knowledge structures, such as ontologies, can provide valuable domain knowledge and user information. However, acquiring such knowledge and keeping it up to date is not a trivial task and user interests are particularly difficult to acquire and maintain. This paper investigates the synergy between a web-based research paper recommender system and an ontology containing information automatically extracted from departmental databases available on the web. The ontology is used to address the recommender systems cold-start problem. The recommender system addresses the ontology's interest-acquisition problem. An empirical evaluation of this approach is conducted and the performance of the integrated systems measured

    MECHANISMS OF GOVERNANCE OF SUSTAINBLE DEVELOPMENT

    In this paper we incorporate the interdisciplinary New Institutional and Transaction Costs Economics (combining Economics, Organization, Law, Sociology, Behavioural and Political Sciences), and suggest a framework for analyzing the mechanisms of governance of sustainable development. Our new approach takes into account the role of specific institutional environment; and the behavioural characteristics of individual agents (personal preferences, bounded rationality, tendency for opportunism, trust, risk aversion); and the transaction costs associated with the various forms of governance; and the critical factors of economic activity and exchanges (such as appropriability, frequency, uncertainty, and asset specificity of transactions); and the comparative efficiency of market, private, public and hybrid modes; and the potential of production structures for adaptation; and the comparative efficiency of alternative modes for public intervention. Agricultural sector is used to illustrate that new approach and support with examples.institutions, market, private, public and hybrid modes, agrarian sustainability

    Towards the Framing of Venture Capital Policies: a Systems-Evolutionary Perspective with Particular Reference to the UK/Scotland and Israeli Experiences

    Get PDF
    We compare some of the policies that have been attempted in Europe (UK/Scotland) and Israel over the past fifteen years to elaborate a new Systems Evolutionary (SE) framework for rethinking VC policy and related ITP. We argue that this perspective is useful for both real world (‘positive’) analysis and policy (‘normative’) analys is. Our SE framework is shaped by (i) a multidimensional view of VC; (ii) strong between VC, VC policy and the development of EHTCs; and (iii) a strategic approach to policy. In contrast, many VC policies in Europe up to and including the 1990s took a ‘static’ financial view of VC that focused on ‘bridging existng early phase finance gaps of innovative companies’ rather than creating of a new mechanism to assure the timely growth of EHTCs. We aim to present the new framework rather than to provide specific recommendations. The main conclusion is that the success of VC policies depend on factors such as the phase of evolution of (i) VC or related innovation finance organizations; (ii) the underlying segment of start up companies and of high tech industries; (iii) the specific country/region institutional setting. While in some contexts it may be worth considering the targeting of a new VC industry/market (and associated EHTC) in others the focus of policy should center in improving pre-emergence conditions. More specifically it may be, given that VC searches for ‘investment ready opportunities’, that ITP should, in many contexts, precede VC policies. Another key conclusion is that implementing this perspective necessitates the creation of a strategic level of policy, with a view of specifying a set of strategic priorities for Scie nce, Technology, and Innovation, priorities that should precede rather than follow policy design and implementation. A major challenge is to extend the present framework that was initially based on VCs oriented towards ICT to LS.

    New Directions in Compensation Research: Synergies, Risk, and Survival

    Get PDF
    We describe and use two theoretical frameworks, the resource-based view of the firm and institutional theory, as lenses for examining three promising areas of compensation research. First, we examine the nature of the relationship between pay and effectiveness. Does pay typically have a main effect or, instead, does the relationship depend on other human resource activities and organization characteristics? If the latter is true, then there are synergies between pay and these other factors and thus, conclusions drawn from main effects models may be misleading. Second, we discuss a relatively neglected issue in pay research, the concept of risk as it applies to investments in pay programs. Although firms and researchers tend to focus on expected returns from compensation interventions, analysis of the risk, or variability, associated with these returns may be essential for effective decision-making. Finally ,pay program survival, which has been virtually ignored in systematic pay research, is investigated. Survival appears to have important consequences for estimating pay plan risk and returns, and is also integral to the discussion of pay synergies. Based upon our two theoretical frameworks, we suggest specific research directions for pay program synergies, risk, and survival
