For the maintenance and development of a disaggregated econometric model, the present paper deals with some aspects related to the identification of important intermediate transactions. First, some methodological aspects related to earlier works are discussed. By comparing the properties of different selection methods based on the recent West German input–output table, the calculations confirm the common finding that the necessary level of endogenization can be bounded meaningfully by an a priori investiga tion of the intersectoral transactions. This is also valid if the selection method considers restrictions that deal with the consistence of input–output tables and if some broader error criteria are applied. The main result of the empirical applications seems to be that some attention should be paid to temporal changes of important coefficients.  相似文献

This article identifies key features of the strategy concept as a basis for reviewing existing theories of strategy. It also provides an agenda for future research. the article argues that there is a decision hierarchy in a firm, and defines strategy as the highest-level decision in the hierarchy. Consequently, strategy has to exhibit what may be called three features of dominance: vertical dominance, horizontal dominance, and dynamic dominance. A vertically dominant strategy is one that determines, directly or indirectly, other decisions of a firm. A horizontally dominant strategy seeks to optimize the value of the firm according to some criteria. Dynamic dominance implies that strategy should affect the subsequent decisions of a firm over a relevant period of time. With few exceptions, existing theories of strategy are issue-oriented and focus largely on horizontal dominance. More research should, therefore, be directed towards vertical and dynamic dominance criteria. If a comprehensive theory of strategy which satisfies the three dominance features cannot be developed, it is suggested that development should be directed towards integrating behavioural and economic approaches.  相似文献

In this study, the author analyzes the 1990 U.S. Supreme Court decision inAtlantic Richfield Company vs. USA Petroleum Company approving Atlantic Richfield’s maximum pricing plan improsed on its distributors (despite the Court’s recognition that theper se rule forbade such schemes). Theper se rule had been one of the last substantial measures of effective antitrust policy administered by enforcement authorities and the courts, perhaps even more fundamental than scrutiny of proposed mergers and predatory practices. That principle has been weakened by the ARCO decision. The author addresses some of the likely consequences of the ascendancy of the Chicago School and the NeoClassical theory generally in antitrust interpretation.  相似文献

Monopoly zoning by local governments has been studied extensively since the original article by White [1975, in: E. Mills and W. Oates, eds., Fiscal zoning and land use controls (Lexington Books, Lexington, MA)]. However, little or no attention has been paid to the possibility of monopolistic discrimination under such a regime. The question is: When will zoning multiple lot sizes be feasible given that buyers with different valuations of land cannot be coerced into purchasing particular lots? The literature on imperfect price discrimination by monopolists is brought to bear on this question. It is shown that the resulting zoning strategy may or may not involve multiple lot sizes. The factors determining the optimal strategy are studied in detail, with particular emphasis on the nature of the market for undeveloped land in the community.  相似文献

Supervisor's human resources (HR) decisions have a significant impact on the employees they manage but have been found to be subject to bias. The upward influence tactics use by subordinates can play a role in this. We investigated the effects of seven upward influence tactics on supervisor job‐performance ratings and the extent of subordinate flexible working arrangements (FWAs). Supervisors are often responsible for determining whether employees are granted FWAs. We posit an alternative theoretical mechanism by which upward influence tactics bring about their effects, mediated through two distinct types of respect, mutual appraisal respect and mutual recognition respect. We collected data from 389 matched supervisor–subordinate dyads, and found that both mutual appraisal respect and mutual recognition respect mediated relationships between several upward influence tactics and both job‐performance ratings and FWAs. Our findings show that upward influence tactics affect the quality of the relationship between employees and their supervisors, specifically, these two forms of mutual respect. Further, both mutual appraisal respect and mutual recognition respect may explain why supervisors show favoritism to some subordinates over others, in reaching HR decisions in these areas.  相似文献

Evaluating the British Model of Electricity Deregulation   总被引:3,自引:0,他引:3  
Abstract ** :  A key aspect of the 1990 reforms to the British electricity supply industry was the introduction of a formal system of regulation by an autonomous regulatory body. It was expected that replacement of monopolies in some areas by markets and price‐setting in monopoly areas using a simple incentive formula would mean that regulation of the industry would be 'light'. This article examines how regulation has turned out in practice. It concludes that the promise of 'light' regulation has not been fulfilled. Regulation of competitive markets is a major regulatory activity, incentive regulation has evolved into a complex and intrusive form of rate‐of‐return, while regulation of industry structure has allowed the industry to descend into a concentrated, vertically integrated structure, at odds with the aims of the reforms .  相似文献

This research suggests that a random coefficient regression model is well-suited for analyzing long-run versus short-run movements in wages and unemployment and is an improvement over some empirical techniques typically used.  相似文献

The growth of government budgets can be broken down into a-institutional and institutional components. The former component — the familiar substitution, income, and population/public goods-tax sharing effects — is estimated to contribute about two-fifths of the growth of U.S. government spending. The latter component — rent-seeking political redistributions, bureaucracy and perceptual/informational impedimentia — is important, too, but an exact imputation cannot be asserted given the state of the art in empirical public choice theory. The cross-effects on spending of the growth of regulation and tax preferences or tax expenditures, though interesting, is not pursued.  相似文献

Delphi and other methods of using expert opinion to generate forecasts can be a useful tool for planning, impact assessment, and policy analysis. Unfortunately, little is known about the accuracy of forecasts produced using these methods, so their utility is limited at present. Based on the logic of the Delphi method, I suggest that: 1) forecast accuracy should increase across rounds of a Delphi iteration, 2) there is a positive correlation between a panelist's uncertainty about a forecast and his or her shift in forecast from round to round, 3) forecasts weighted by self-reported confidence will be more accurate than unweighted forecasts, and 4) the use of robust estimates of location as summaries of expert opinion yield better forecasts than nonrobust measures. A Delphi experiment provides little support to any of these hypotheses. This finding suggests that traditional assumptions about the proper methods for analyzing a Delphi study may be inappropriate.  相似文献
