The theme is Arrow's requirement in his theorem of 1951 on methods for group choice, that the choice be independent of irrelevant alternatives. The attention is drawn to (1) his own explanation of this requirement in 1972, which is a quite different understanding than has been discussed in the voluminous literature on the theorem, (2) that Arrow, in fact, in 1985 showed an understanding for how irrelevant alternatives might in a meaningful way influence the group choice, (3) that admittedly the border-line between irrelevant and relevant alternatives in Arrow's original statement is arbitrary, and (4) that Arrow, if he had observed the final thought in the origin of the group theory by Borda, which he admittedly did not, might have realized that Borda's method stringently estimates the relevance of each alternative for the result.The author expresses his surprise that a theoretical conclusion based on an arbitrary fundament has been admired so long. 相似文献

The impressive and spontaneous build-up of the private small and medium-sized enterprises (SMEs) in the Czech Republic in 1990–93 coincided with the similarly dramatic changes in the public administration and in the whole environment for decision-making. The resulting problems of SMEs in the Czech Republic seem to be common to all economies in transition. A lot of the problems are caused by the macroeconomic policy for which this sector is not the most important part of the national economy. The paper shows some conflicts between macroeconomic anti-inflationary (monetary and fiscal) policies, and interests of small businesses. The authors stress the importance of SMEs during the period of transition. Informal aspects of the functioning of small firms are discussed, especially their relation with banks and public administration. The paper offers some empirical evidence and available statistics on SMEs developments during 1990–94 focusing particularly on manufacturing. 相似文献

This paper presents a simple model which illustrates the possible policy- and welfare-implications of endogenous product selection in the postal sector. The cost of a unit of mail depends on its "quality" (e.g., speed of delivery) and on the type and location of the addressee (firms, urban households, and rural households). Senders have inelastic demands and differ in their willingness to pay for quality. Addressees are passive but their utility may affect social welfare. Two operators play a two-stage game, first choosing qualities and then prices. We first show that the equilibrium with two private (profit maximizing) operators results in an inefficient provision of quality. Then, we consider the mixed (Nash) equilibrium with one private and one (welfare maximizing) public operator. If the budget constraint of the public firm is not binding, this equilibrium is shown to be first-best efficient even if social welfare accounts for the utility of addressees. If the budget constraint is binding, the mixed equilibrium is not efficient but yields a higher level of welfare than the private equilibrium. Finally, we study the impact of minimum quality standards within our setting. 相似文献

Empirical literature emphasizes a positive contribution of private equity investors, which results from their combined provision
of capital, monitoring, and management support. The aim of this study is to show that these previous results, which are based
mostly on the analysis of US independent closed-end private equity funds, cannot be generalized since the private equity industry
should not be treated as homogenous. We argue that it is necessary to distinguish between different types of private equity
providers because their differing governance structures, strategic goals and experiences have a decisive influence on their
value adding activities. The results of this study—which uses a data set of 179 German private equity-backed companies—are
consistent with the conjecture that independent and corporate private equity providers tend to have a more pronounced role
in corporate governance and monitoring of the companies they finance, than bank-dependent and governmental funds which often
serve only as bridge investors.

The objective of this paper is to evaluate the impact on bank credit exposures to small- and medium-sized Spanish firms of the current proposal for reform of the 1988 Capital Accord using information from the Spanish Credit Register. Capital requirements for exposures to those firms, according to the various revisions of the proposed capital reform (from the January 2001 consultative document to the April 2003 one), are calculated to analyze whether the existing pattern of bank financing of small- and medium-sized firms might be altered. Finally, the incentives for individual banks to adopt the advanced internal ratings-based approach proposed by Basel II are evaluated. 相似文献

We investigate organisational and environmental factors that influence firms’ incentives to develop high-quality internal audit functions (IAFs) by using a unique international sample formed by matching proprietary data from a global internal auditor survey with public data obtained from Worldscope. Concerning organisational factors, we find that a positive relationship exists between IAF quality and firm complexity and confirm that complex firms have a higher demand for monitoring and advising and, therefore, a greater need for formal controls. In addition, IAF quality is positively related to board monitoring and audit committee diligence but negatively associated with CEO power, which suggests that IAF quality is influenced by other key players in corporate governance. Regarding environmental factors, we document that IAF quality is positively associated with industry competition, which implies that a firm’s incentive for a high-quality IAF is enhanced when confronted with greater environmental uncertainty. Furthermore, IAF quality has a significantly positive relationship with our self-constructed index of IAF requirements included in national corporate governance codes, which indicates that strong home-country corporate governance codes play a role in fostering IAF development. 相似文献

This paper investigates how welfare losses for facing high-order risk increases change when the risk environment of the decision maker is altered. To that aim, we define the nth-order utility premium as a measure of pain associated with facing the passage of one risk to a more severe one and we examine some of its properties. Changes in risk are expressed through the concept of stochastic dominance of order n. The paper investigates more particularly welfare changes of merging increases in risk, first ignoring background risks, then taking them into account. Merging increases in risk may be beneficial or not, depending on whether background risks are considered and how. The paper also provides conditions on individual preferences for superadditivity of the nth-order utility premium. The results confirm the importance and usefulness of two analytical concepts: mixed risk aversion and risk apportionment. 相似文献

The North-America Free Trade Agreement (NAFTA) has brought together the economies of Canada, Mexico, and the US into forming one of the largest trading blocs worldwide (within the top CO2 emitters). However, the current global protectionist discourse threatens the agreement. This paper analyzes the energy and energy-related CO2 emission relationships between NAFTA countries in 2014 to gain insights into the climate change implications of current integration and the possible cancelation of the agreement. The analysis is performed with a multi-regional version of the multi-factor energy input–output model. The results show that NAFTA has not built a single integrated energy system, though it has helped reduce energy-related CO2 emissions. Moreover, if NAFTA is not revoked, further integration would depend on the capacity of the Mexican energy sector to converge to the performance of its trade partners’ energy sectors. Conversely, a broken deal would induce negative environmental externalities. 相似文献

A new approach to allocate environmental responsibility, the ‘value added-based responsibility’ allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specific supply chain. We show that – due to their position in global value chains – certain sectors (e.g. services) and countries (e.g. Germany) receive significantly greater responsibility compared to other allocation approaches. This adds a new perspective to the discussions concerning a fair distribution of mitigation costs among nations, companies and consumers. 相似文献
