John Dewey frequently praised Henry George, author of a plan to confiscate land values with a “single tax.” Scholars have failed to account for Dewey's support of George. Some have argued that it should not be taken seriously because it is at odds with their interpretation of Dewey's philosophy. This article demonstrates that Dewey perceived the socialization of land values as an essential step toward creating a true democracy. Furthermore, Dewey's interest in George was not an aberration; it was exemplary of his faith in ideology, theory, and transformative social policy. Despite contentions to the contrary, pragmatists of the early 20th century never emphasized skepticism, moderation, or rote empiricism. In fact, Dewey embraced the philosophy of Henry George as a general theory of history of society. During the Great Depression, Dewey attacked the piecemeal reformism of the New Deal in favor of the comprehensive vision of Henry George.  相似文献

Drawing upon a series of interviews conducted with leading practitioners and opinion formulators in the social, ethical and environmental audit arena, together with an extensive review of recent literature in the area, this paper offers a critical appraisal of current developments in the newly revitalized social audit movement. We particularly question whether in their enthusiasm for bringing social audit into the mainstream of current business thinking its advocates risk compromising the democratic ideals of the founding fathers of the movement. A particular concern raised is that without real change in corporate governance structures, social audit could become monopolized by consultants and/or corporate management and hence amount to little more than a skilfully controlled public relations exercise.  相似文献

Research has called into question the impact of the World Trade Organization (WTO) on trade. This research, however, has been called into question on both modeling grounds for and failing to utilize comprehensive fixed effects. Others have found that when these factors are accounted for, imports rise by significant amounts. This paper seeks to reconcile these findings. I find that the WTO has a larger, though uneven, impact on exports than imports. The results indicate that the WTO frequently causes imports and exports to move in opposite directions negating any increase in overall trade. The regressions with and without fixed country effects generally demonstrate pattern consistency for generalized results that are robust to change. Owing to the finding that imports rise modestly or even fall without country effects while exports rise, the results imply that countries may not be as interested in liberalizing trade as selling to the world.  相似文献

The results of an econometric exercise are presented, showing that Monetary Policy Committee (MPC) members appointed from outside the ranks of Bank of England staff (outsiders) react differently to forecasts of inflation and output than those appointed from within the Bank (insiders). All results are reinforced by the well‐established findings that, compared with outsiders, insiders choose higher interest rates, are more likely to vote as a bloc, and feature on the winning side of policy decisions more frequently. On the basis of these results, it is argued that the current MPC framework is biased toward the policy choices of insiders.  相似文献

In an environment in which the primitive is the space of distribution functions, we characterize the quantile functions by the axioms ordinal covariance, monotonicity with respect to first-order stochastic dominance, and upper semicontinuity. We show how to characterize the VaR in a similar manner.  相似文献

Managing radical innovation: an overview of emergent strategy issues   总被引:15,自引:0,他引:15  
Despite differences in definitions, researchers understand that radical innovation within an organization is very different from incremental innovation , and and that it is critical to the long-term success of firms. Unfortunately, research has also shown that it is often difficult to get support for radical projects in large firms [14], where internal cultures and pressures often push efforts toward more low risk, immediate reward, incremental projects. Interestingly, we know considerably less about the effective management of the product development process in the radical than in an incremental context. The purpose of this study is to explore the process of radical new product development from a strategic perspective, and to outline key observations and challenges that managers face as they move these projects to market. The findings presented here represent the results of a longitudinal (since 1995), multidisciplinary study of radical innovation projects. A multiple case study design was used to explore the similarities and differences in management practices applied to twelve radical innovation projects in ten large, established North American firms. The findings are grouped into three high-level strategic themes. The first theme, market scope, discusses the challenges associated with the pursuit of familiar versus unfamiliar markets for radical innovation. The second theme of competency management identifies and discusses strategic challenges that emerge as firms stretch themselves into new and unfamiliar territory. The final theme relates to the people issues that emerge as both individuals and the project teams themselves try to move radical projects forward in organizations that are not necessarily designed to support such uncertainty.A breadth of subtopics emerge within and across this framework relating to such ideas as risk management, product cannibalization, team composition, and the search for a divisional home. Taken together, our observations reinforce the emerging literature that shows that project teams engaging in radical innovation encounter a much different set of challenges than those typically faced by NPD teams engaged in incremental innovation.  相似文献

In this paper, we characterize the multiperiod minimum-risk hedge strategy within the stochastic volatility (SV) framework and compare it to other hedge strategies on the basis of hedging performance. Using crude oil markets as an example, we demonstrate that the SV model is appropriate in depicting price behaviour. However, ex ante and ex post comparisons indicate that the SV strategy is inferior to conventional hedging strategies. There is also evidence that the Generalized Autoregressive Conditional Heteroskedasticity (GARCH) strategy may be better than the SV strategy, at least in terms of variance reduction.  相似文献
