In this paper the author suggests a number of reasons why in recent years there appears to have been a shift in thinking away from traditional bureaucratic-scientific forms of organization to alternative types of organizational design. In most cases, that thinking has yet to be translated into practial action. Experiments in organizational design are taking place but progress appears to be hindered by the lack of a sufficiently well understood design theory, a clearly existing model to emulate, and not least by a failure to know how we get from “where we are” to “where we want to be”. The author describes some of the basic characteristics of what have been called “high commitment—high performance” organizations, and concludes by offering a step-model towards the creation of such an organization. 相似文献

We examine how the rationale for enabling versus precluding private antitrust enforcement depends on whether antitrust enforcement is corruption-free or plagued by corruption. Corruption in courts affects the incentives to bring forth private antitrust lawsuits. This, in turn, along with corruption in antitrust agency enforcement, alters the incentives to commit antitrust violations. The social welfare effect of enabling private antitrust enforcement in the presence of corruption depends on whether corrupt officials in the ensuing bribery contests favor a particular firm and if so which one and to what extent. Under some circumstances, corruption actually increases the social desirability of private antitrust enforcement relative to the no-corruption scenario. Our analysis highlights that the effects of a given legal arrangement for antitrust enforcement critically depend on the corruption environment and, thus, that the appropriate design of antitrust institutions is context-specific. 相似文献

We study a dynamic duopoly model with network externalities. The value of the product depends on the current and past network size. We compare the market outcome to a planner. With equal quality products, the market outcome may result in too little standardization (i.e. too many products active in the long run) but never too much. The potential inefficiency is non-monotonic in the strength of the network effect, being most likely for intermediate levels. When products differ in quality, an inferior product may dominate even when the planner would choose otherwise, but only if the discount factor is sufficiently large 相似文献

Under what conditions do times of increasing uncertainty, such as the ongoing global turmoil, call for international policy harmonization? We shed light on this question by developing a model of interjurisdictional policy coordination taking place under incomplete information and featuring uncertainty about jurisdictions' politico-economic fundamentals. We show how the effect of an increase in uncertainty on the desirability of policy harmonization varies with the pattern of asymmetries in jurisdictions' scale, mutual influence, and magnitude of the increase in uncertainty. Our analysis suggests that the case for policy harmonization as a governance response to growing uncertainty is not compelling. 相似文献

We apply the concept of free random variables to doubly correlated (Gaussian) Wishart random matrix models, appearing, for example, in a multivariate analysis of financial time series, and displaying both inter-asset cross-covariances and temporal auto-covariances. We give a comprehensive introduction to the rich financial reality behind such models. We explain in an elementary way the main techniques of free random variables calculus, with a view to promoting them in the quantitative finance community. We apply our findings to tackle several financially relevant problems, such as a universe of assets displaying exponentially decaying temporal covariances, or the exponentially weighted moving average, both with an arbitrary structure of cross-covariances. 相似文献

It is well documented that financial literacy is at best moderate around the world and that the cost of ignorance in this field may be high on both microeconomic and macroeconomic levels. We surveyed a representative sample of Poles to measure their debt literacy—a little‐studied aspect of financial literacy—and therefore obtain insight into the factors predicting it. Our study evidenced low levels of debt literacy and its overestimation by respondents in their self‐reports. We also confirmed some of the patterns found in former studies, including the gender gap and a positive relationship between the level of educational attainment and debt literacy. Finally, our examination provides compelling outcomes with regard to the segmentation of the sample on the basis of objective and subjective debt literacy scores. They show large heterogeneity of debt literacy and thus confirm the need for far‐reaching customization of debt‐oriented education. 相似文献

The existence of a competitive equilibrium for an economy with a measure space of agents is proved by reducing the economy to a three-person game and then applying Debreu's lemma (1952). In addition to the relative simplicity and shortness of the proof, we generalize known results [Aumann (1966), Hildenbrand (1970), Schmeidler (1969)] by allowing both price dependent preferences and satiation. 相似文献

This paper presents a discussion of methodological issues in multiobjective analysis, encompassing various approaches to multiobjective optimization and decision making. The main thesis is that while there are already many methods for multiobjective analysis, this field would gain from further methodological reflection. 相似文献
