ABSTRACT ** : We provide a new explanation for commercial activities by non‐profit organizations whose primary concern is to supply mission output. Starting from the observation that donations to individual non‐profits are often highly volatile, we show how investment in commercial activity can constitute a form of insurance for mission activity. Although investment in commercial activity has an opportunity cost in terms of capacity to produce mission output, if donations turn out to be low the commercial revenue will enable cross‐subsidization of mission output. The equilibrium commercial investment is (weakly) positively related to the degree of risk aversion.  相似文献

The paper applies the collective model to the analysis of intra-household inequality using one of the subjective-qualitative questions available in the RLMS (Russia Longitudinal Monitoring Survey) data, and provides a test for its assumptions. Interpreting the individual answers as reported budget scales we assume a correspondence between the budget level that household members report and their true income sharing. We first show that this assumption is supported by the data, and then use couples who report the same level of budget to identify the full sharing rule for the whole sample.  相似文献

New Zealand (NZ) dairy farms used to be the lowest input and most efficient dairy farms of the world. However, intensification of the traditional pasture-based system has occurred over the last decade and has not always been accompanied by increased efficiency. The purpose of this paper is to produce an updated reference of the eco-efficiency of NZ dairy farm systems and to analyse the implications of intensification on their eco-efficiency. Results for an average NZ dairy farm system were compared with those for three dairy farmlet systems representing a wide range in intensification practices. A low input system (LI) (no N fertiliser, no brought-in feed supplement, stocking rate of 2.3 cows/ha) was compared with an N-fertilised farm system (NF) (170 kg fertiliser-N/ha/year, 3 cows/ha) representing a first level of intensification and with an N-fertilised and maize silage supplemented system (NFMS) (170 kg fertiliser-N/ha/year, 13 t DM maize silage/ha/year, 5.2 cows/ha), representing a possible future intensification option. Their eco-efficiency in terms of milk production and land use was compared using Life Cycle Assessment (LCA) methodology. NZ dairy farm systems rely on favourable temperate climate conditions and long-term perennial ryegrass/white clover pasture, to achieve eco-efficient milk production and land use compared to European systems. However, intensification of NZ dairy farms was shown to be detrimental to their eco-efficiency in terms both of milk production and land use functions and could greatly reduce their advantage compared to European systems. The eco-efficiency of LI was very high whatever the functional unit which is remarkable from an LCA perspective. NF and NFMS had a similar eco-efficiency except for energy use which corresponded to the most critical hot spot of NFMS. All studied NZ systems presented some areas for improvement where some new technologies available for dairy farms might play a promising role in the future. Finally, it should be highlighted that the comparison with European studies based on the literature available needs validation through a more comprehensive study using harmonised methodology and assumptions across countries.  相似文献

This article examines alternative approaches to conflict resolution by developing a theoretical framework that relates dispute resolution practice to philosophical assumptions about authority and knowledge. By investigating the assumptions underpinning interest‐based bargaining and mediation their link to direct democracy and challenge to managerial authority are revealed at the level of theory and practice.  相似文献

Professionals are knowledge experts who create customized solutions for clients. Many professionals practice in the context of strong professional institutions that prescribe intense socialization and codes and norms. While some professionals work as employees, many start their own firms in order to practice. Firm start-up for professionals is more prevalent than for most other occupations. While professional institutions often constraint their activities, firm start-up for professional service entrepreneurs (PSEs) involves similar entrepreneurial activities as other entrepreneurs, creating an interesting paradox worth investigating. This paper explores the uniqueness of PSEs and the firms they start, and the distinctiveness and value of research in the context of PSEs and professional service firms.  相似文献

Family income and child outcomes in Canada   总被引:1,自引:0,他引:1  
Abstract.  A positive relationship between income and child outcomes has been observed in data from numerous countries. A key question concerns the extent to which this association represents a causal relationship as opposed to unobserved heterogeneity. We use data from the National Longitudinal Survey of Children and Youth to implement a series of empirical strategies for estimating the existence and size of the effect of income on three measures of cognition. Our results indicate that the effect of income on these outcomes may well be positive, but that it is likely to be smaller than conventional estimates. JEL Classification: I10  相似文献

We model the effects of license fees and bureaucratic delay on firm entry into a new competitive industry, whose profitability is initially unknown. A license fee alone reduces the number of first movers and the steady‐state number of firms. The combination of license fee and delay may cause some entrepreneurs to purchase licenses speculatively, only using them to enter production later if profitability is revealed to be sufficiently favourable. Alternatively, some entrepreneurs may wait, possibly buying a license only after profitability is revealed; but it is never found that some entrepreneurs adopt one of these strategies and some the other.  相似文献

论流转税税负转嫁中的增值税   总被引:1,自引:0,他引:1  
运用税负转嫁理论对我国现实经济生活中的问题,尤其是对主体税种——流转税中的增值税的转嫁问题进行了详细分析。否定了“作为价外税的增值税全部转嫁给消费者”这样一种观点,指出了增值税应该由生产者负担,即生产者是设计的税负人。但增值税又具有转嫁的可能性。在此基础上,归纳了增值税转嫁规律。  相似文献
