The paper considers the problem of comparing income distributions for heterogeneous populations. The first contribution of this paper is a precise dominance criterion combined with a simple algorithm for implementing the criterion. This criterion is shown to be equivalent to unanimity among utilitarian social planners whose objectives are compatible with given intervals of equivalence scales. The second contribution of the paper is to show that this criterion is equivalent to dominance for two different families of social welfare functions, one inspired by Atkinson and Bourguignon (in: G.R. Feiwel (Ed.), Arrow and Foundation of the Theory of Economic Policy, Macmillan, London, 1987), in which household utility is a general function of income and needs, and a second family inspired by Ebert (Soc. Choice Welfare 16 (1999) 233), in which household utility is a function of equivalent incomes. Finally, we extend our results to the case where the distributions of needs differ between the two populations being compared. 相似文献

We present two numerical examples of multiple admissible minima obtained by using the Cochrane-Orcutt iterative technique: a forgotten and somewhat farfetched example, constructed by Hildreth and Lu, and a new example, based on more typical economic data. 相似文献

This study investigates the impact of headquarters–subsidiary interdependencies on performance evaluation and reward systems in multinational enterprises. Headquarters–subsidiary interdependencies refer to the extent to which headquarters and subsidiaries depend on each other to accomplish their tasks. When headquarters–subsidiary interdependencies are present, it becomes more difficult to reward the performance of subsidiary managers because these interdependencies induce noise on subsidiary-level accounting performance measures, while at the same time high levels of goal alignment between headquarters and subsidiary managers are required. Based on survey data from 82 foreign subsidiaries operating in Belgium with headquarters in 14 different countries, our partial least squares path modelling results show that as headquarters–subsidiary interdependencies increase, headquarters use more participative performance evaluation and consider more the effects of uncontrollable factors on subsidiaries' performance when rewarding subsidiary managers. More importantly, while prior research suggests that interdependencies induce noise on unit-level accounting performance measures, our results indicate that participative performance evaluation may mitigate the noise so that headquarters still rely on subsidiary formula-based compensation using accounting measures to reward subsidiary managers. 相似文献

Export processing zones (EPZs) have become widespread with the liberalisation of international trade and investment. They are key players in the deepening of the global value chain (GVC). However, little is known about their contribution to world trade due to a lack of information on their location and status. This paper sets out to improve knowledge in this area by analysing the trade performance of EPZ countries at macro‐level with a focus on EPZ externalities and distortive costs. We have built an original database of EPZs in which we define them as processing zones benefiting from import tariff incentives. We show that EPZs increase trade only by easing the negative impact of protection. As importers of components and raw materials, they raise the rest of the world's exports. This confirms the contribution of EPZs to the GVC. This result is robust to a change in the model specification, errors and bias due to data collection issues and sample composition. 相似文献

Previous research in the social responsibility/social performance area has failed to systematically address the institutional determinants of social responsibility and its various manifestations in terms of social performance. This paper examines the relationship between the configuration of institutional structures at various levels and the necessary and sufficient conditions for the concept of social responsibility to manifest in the practice of stakeholder management. In particular we hypothesize that smaller, closely held firms in profitable niches are in the optimum position to practice stakeholder management, assuming the management of these firms is predisposed to do so. 相似文献

Peek and Rosengren [Peek, J., Rosengren, E., 2005. Unnatural selection: Perverse incentives and the misallocation of credit in Japan. American Economic Review 95, 1144–1166] showed that, when the bubble economy era ended, regulatory forbearance and perverse incentives allowed Japanese banks to engage extensively in evergreening. This is the first comprehensive study to empirically analyze the economics of private debt restructurings of financially distressed companies in Japan, where the corporate monitoring mechanism is not market based but large-stakeholder based – typically, banks and affiliated companies. These stakeholders are expected to efficiently resolve potential bankruptcy or collapse with better information resulting from long-term relationships with the distressed firms. Our study, however, finds that private restructurings led by them failed because of delays in implementing fundamental solutions. Forbearance in addressing the needs of distressed firms demonstrates the weakness of such stakeholders in instituting discipline, hence the need for a system to “monitor the monitor”. 相似文献

Product architecture decisions regarding, for example, product modularity, component commonality, and design re-use, are important for balancing costs, responsiveness, quality, and other important business objectives. Firms are challenged with complex tradeoffs between competing design priorities, face the need to facilitate communication between functional silos, and want to learn from past experiences. In this paper, we present a qualitative approach for systematically evaluating the product architecture of a product family, comparing the original architecture objectives and actual experiences.
The intended contribution of our research is threefold: (1) to present a framework that brings together a diverse set of product architecture-related decisions and business performance; (2) to provide a set of metrics that operationalise the variables in the framework, and (3) to provide a workshop protocol that is based on the framework and the metrics. This workshop aims to improve cross-functional communication about the product architecture of an existing product family, and it results in practical improvement actions for future architecture design projects. Experiences with this approach are reported in pilots with Philips Domestic Appliances and Personal Care, and Philips Consumer Electronics. 相似文献

BESSEL PROCESSES, ASIAN OPTIONS, AND PERPETUITIES 总被引:11,自引:0,他引:11
Using Bessel processes, one can solve several open problems involving the integral of an exponential of Brownian motion. This point will be illustrated with three examples. The first one is a formula for the Laplace transform of an Asian option which is "out of the money." The second example concerns volatility misspecification in portfolio insurance strategies, when the stochastic volatility is represented by the Hull and White model. The third one is the valuation of perpetuities or annuities under stochastic interest rates within the Cox-Ingersoll-Ross framework. Moreover, without using time changes or Bessel processes, but only simple probabilistic methods, we obtain further results about Asian options: the computation of the moments of all orders of an arithmetic average of geometric Brownian motion; the property that, in contrast with most of what has been written so far, the Asian option may be more expensive than the standard option (e.g., options on currencies or oil spreads); and a simple, closed-form expression of the Asian option price when the option is "in the money," thereby illuminating the impact on the Asian option price of the revealed underlying asset price as time goes by. This formula has an interesting resemblance with the Black-Scholes formula, even though the comparison cannot be carried too far. 相似文献

Previous research studies the age profile of patent citations to learn about knowledge flows over time. However, identification is problematic because of the collinearity between application year, citation year, and patent age. We show empirically that a patent's ‘citation clock’ does not start until it issues, and propose a highly flexible identification strategy that uses the lag between application and grant as a source of exogenous variation. We examine the potential bias if our assumptions are incorrect, and discuss extensions into other research areas. Finally, we use our method to re‐examine prior results on citation age profiles of patents from different technological fields and application year cohorts.
