This research aims to identify empirically the success factors that have allowed small and medium‐sized enterprises (SMEs) to obtain advantages from electronic data interchange (EDI). These advantages can be operational, managerial, and strategic in nature. Results of a field study done in 39 firms indicate that it is the quality of the organizational context of EDI (organizational support, implementation process, and control procedures) that is crucial to the attainment of benefits from this technology. In turn, the quality of the organizational context is higher when the small firm implements EDI voluntarily rather than having it imposed by a major client or supplier. These results are compared with those of a prior study done in a large business context. 相似文献

This paper examines some current reforms to social security benefits / tax credits and changes to employment provisions from a gender perspective. It analyses tensions between the trend towards ‘individualisation’ and growing emphasis on the couple/household as a policy focus. New tax credits change the distribution of resources within many couples. Incentives to work for some second earners should improve; but extending in‐work subsidies to childless couples raises questions. Payment of child tax credit to the ‘main carer’ has been welcomed, though the implications of joint ownership of tax credits are unclear, and joint assessment will be extended. Many claimants' partners can now access employment services. However, this is aimed at reducing the number of workless households rather than expanding individuals' opportunities. Joint claims for jobseeker's allowance, and work‐focused interviews, involve increased responsibilities for partners but no right of access to individual income. A more consistent critical analysis of reform from a gender perspective is required. 相似文献

Hedonic prices of landscape are estimated in the urban fringe of Dijon (France). Viewshed and its content as perceived at
ground level are analyzed from satellite images supplemented by a digital elevation model. Landscape attributes are then fed
into econometric models (based on 2,667 house sales) that allows for endogeneity, multicollinearity, and spatial correlations.
Results show that when in the line of sight, trees and farmland in the immediate vicinity of houses command positive prices
and roads negative prices; if out of sight, their prices are markedly lower or insignificant: the view itself matters. The
layout of features in fragmented landscapes commands positive hedonic prices. Landscapes and features in sight but more than
100–300~m away all have insignificant prices. 相似文献

The objective of this paper is to assess to what extent the cost of patenting affects the demand for patents. The empirical
analysis, which focuses on the patent systems of the USA, Japan, and Europe in 2003, leads to the following methodological
and empirical conclusions: (1) for a proper international comparison, the size of the market and the average number of claims
included in a patent must be accounted for; (2) when the cost per claim per capita (the 3C-index) is considered, a negative
linear relationship appears between the cost of patenting and the number of claims that are filed; (3) after the grant of
a patent by the EPO, the translation, validation and transaction costs induced by an effective protection in several European
countries witness a highly fragmented and very expensive European market for intellectual property; (4) for a patent designating
13 European countries, the 3C-index is about ten (two) times higher than in the US (Japanese) system (for process and translation
costs up to the grant); (5) The European market being more than twice as large as the US market in terms of inhabitants, the
3C-index suggests that there would be a clear justification for higher nominal examination fees at the EPO, that would ensure
the pursuit of a rigorous granting process. 相似文献

This paper generalizes to uncertaintly the neoclassical one-sector model by transforming the basic differential equation on the capital labor ratio into a “stochastic” differential equation. The capital-labor ratio and related economic variables become random variables whose probability distributions vary with time, and the paper is focused on the existence of a steady state denfined by the (probabilistic) stationarity of these variables. An application of the results is given for a specific example with a Cobb-Douglas production function and uncertainty on the saving coefficient, the labor-force rate of growth, and the capital depreciation rate. 相似文献

In a pure exchange economy with two private commodities and one collective externality, a non-tâtonnement process is formulated, which yields a rule for adjusting an effluent charge of the Pigovian type from the level zero (at a laissez-faire equilibrium) up to a level that sustains an optimum. Besides convergence (Theorem 3) and monotonous decrease of the externality (Theorem 2) along a continuous path of price equilibria (Theorem 1), the paper analyses the distributional implications of alternative redistribution schemes for the proceeds of the charge. Various interpretations of the ‘polluters pay’ principle are discussed in conjunction with property rights. 相似文献

This paper reflects upon the use of causal mapping supported by a Group Support System (GSS) in a particular legal setting. The mapping method and GSS tool was used for the forensic analysis of eight major engineering and construction projects where the contractor intended to claim significant compensation (typically in excess of $20m). Necessarily detailed records were kept of every aspect of the analyses and processes adopted. This paper is an examination and reflection upon analysis of these records, with particular attention to the process. The task of capturing the way in which participants (witnesses) in a project ‘make sense’ of a cost and time overrun is an important aspect of forensic analysis as they have an experience based perspective, that has often involved dealing with high levels of complexity as projects move from planned order through to what they describe as “absolute chaos”. In addition the requirement to account for, and be held responsible for, behaviors that that may in retrospect be seen as incompetent raises interesting issues in determining the validity of the data capture and analyses. Moreover, participants’ views regarding the complex causality of outcomes, reflected in the causal map, are tested through the use of a simulation model replicating the causal map. The implications of this approach as a research method for undertaking organizational research are thus considered by drawing upon experiences of using the approach to develop the case for litigation in several disruption and delay claims. In particular the paper addresses the issues related to defensiveness of participants, anonymity, accessing multiple perspectives in a group setting, organizational learning and the ‘changing of mind’ of participants, and developing an organizational memory. 相似文献
