This paper serves as a stimulus to investigators to examine the role organizational politics plays in decisions leading to the abandonment of information systems (IS) projects. While prior research has identified the development of IS projects as a highly political process, where stakeholders may be more concerned about furthering their self-interests than about contributing to the overall success of the project, there has been little research on identifying the political factors contributing to IS project abandonment. Our case demonstrates six types of political action that took place that caused an electronic commerce (e-commerce) project to be abandoned. Finally, when analyzing mistakes and their principal causes, there is one important lesson that we should learn. That is, all organizations make mistakes and there is the potential for learning from project abandonment experiences.  相似文献

This paper analytically examines the existence of equilibrium configurations of competitive firms on an infinite two-dimensional space. It is shown that the Löschian configuration (a regular-hexagonal lattice) and a square lattice are in global equilibrium; the Löschian configuration is in the strongest global equilibrium among the regular lattices (in this sense, spatial competition leads to the social optimum); and the so-called back-to-back configuration is not in equilibrium. These results are in marked contrast to those obtained from a one-dimensional model, implying that spatial equilibrium configurations in a two-dimensional space should not be inferred only from one-dimensional models frequently employed in spatial economics.  相似文献

This study demonstrates that the joint relationship among domestic traded-goods prices, dometic nontraded-goods prices, foreign traded-goods prices, and foreign nontraded-goods prices is important to understanding rejections or confirmations of long-run PPP. This joint relationship is defined as the "cross-country internal relative price structure." For nine of the ten pairs of countries studied, the cross-country internal relative price structure is found to be stationary; thus, factors other than the influence of nontraded-goods prices must be responsible for the rejections of long-run PPP.  相似文献

This paper focuses on the timing, i.e. delay or accelerate, of the declaration of Chapter XI prior to financial insolvency. Chapter XI can be declared by firms who believe that the firm can emerge from bankruptcy protection as a re-vitalized organization. The timing of its selection is proposed to be a function of the level of environmental adversity and organizational attributes, especially slack resources. Recent developments in the bankruptcy code and its usage by firms, suggest the increasing use of managerial prerogative in the selection of Chapter XI prior to financial insolvency. Chapter XI protection can allow firms the necessary time for effective reorganization if managerial intervention is exercised. As a result of a more precise timing of selection and a proactive reorganization, there will be a higher probability of re-emerging from bankruptcy as a revitalized organization.  相似文献

An understanding of the link between the level of inputs and resultant level of outputs is of considerable importance when trying to manage fisheries through input controls. To this end, studies of several fisheries have been undertaken to examine this relationship through the estimation of production functions and frontiers, using either catch weight or revenue as the dependent variable. The choice of the appropriate output variable to use in the analysis will depend on the objectives of the fishermen. Maximisation of catch weight is often proposed as an objective of fishermen rather than maximisation of profits. In this paper, the technical efficiency scores of vessels operating in the Spanish south‐Atlantic trawl fishery are estimated using the stochastic production frontier approach. The production frontiers are estimated with both the weight and the value of the catch as the dependent variable. The results of the analysis suggest that fishermen adopt a range of strategies but relatively few aim to maximise catch weight only. The differences in strategies may reflect heterogeneous attitudes towards risk, with more risk averse fishermen aiming to trade‐off some potential catch value for a more certain quantity of catch.  相似文献

We investigate the propensity of states to propose and adopt laws prohibiting the deduction of intercompany interest or royalties in response to the passive investment company tax minimization strategy (anti-PIC statutes). Using event history analysis with panel data from 1991–2005, we investigate whether regional diffusion theory explains the proposal and adoption of anti-PIC statutes. Our results provide support for the regional diffusion theory explanation, in that both proposing and adopting states have a higher proportion of adopting states in their particular Bureau of Economic Analysis (BEA) region. We find no relationship between decreases in states’ real corporate income tax revenues and their adoption of anti-PIC statutes, but do find that proposals are more common in states with slower growth in real personal income. This study contributes to existing state and local tax policy research by demonstrating that certain types of policy decisions may arise from reasons closely linked to herding behavior.  相似文献

In this paper we develop a portfolio selection theory under regime switching means and volatilities. We use log mean-variance as the portfolio selection criteria and, as a result, the theory is made substantially easier to implement than other existing theories. Moreover, the estimated regimes are easy to interpret as one of the regimes corresponds to the business cycle turning points. Finally, we conduct an asset allocation simulation and obtain reasonable results by introducing an idea of switching volatility targets.  相似文献

Outwardly, the central banks of Australia, Canada, New Zealand, and the U.S. follow somewhat different approaches to controlling inflation. The U.S. does not explicitly target inflation while the other countries do. Canada and New Zealand have target bands for inflation while Australia has a point target. Results in this paper nevertheless find broad similarities in the monetary policies of these countries. Each can be described as having pursued optimal inflation targeting (explicit or implicit), with heavy interest rate smoothing, but perhaps placing little weight on output variability. We argue that interest rate smoothing is used to introduce gradualism into the response of monetary policy to inflation. We show that given heavy interest rate smoothing, a concern for output variability is redundant.  相似文献

The deregulation of air routes between London and Dublin has brought travellers the benefits of competition; and, hardly surprisingly, as prices have fallen the numbers making the journey have increased. Sean Barrett, Lecturer in Economics, and Mark Purdy of Trinity College, Dublin, compare the effects of liberalisation with those of the restricted entry to the European air transport market. How long, they ask, will the European consumer be denied similar benefits?  相似文献
