We examine the determinants of US equity trader choice of electronic versus intermediated execution. While traders exhibit a strong overall preference for automation, when the market is less liquid at order submission time, traders seek market maker automated and human order‐matching services more often. Traders' overall tendency to choose intermediaries is highly correlated with their demand for liquidity. Market maker participation rates are higher for more active and larger size traders. Traders who choose intermediaries more often trade more stocks, execute orders quicker, price orders more aggressively, and disperse their trading over longer periods of time. Although US stock intermediaries continue to lose market share, our results highlight the important role these firms can play in an increasingly automated, electronically driven marketplace.  相似文献

This paper analyzes consumer responses to lighter child-resistant mechanisms using an original sample of 200 households with young children. Results from an in-house placement of lighters indicate that the child-resistant mechanism would diminish consumer care. The child-resistant device reduced risk perceptions, parental concern with lighter safety, the assessed need for precautions, and consumer care. The results provide the most detailed empirical evidence of the mechanisms driving the diminished safety precautions in response to technological improvements in safety. The overall efficacy of the mechanism, however, is sufficient to generate a safety improvement despite the diminished care.  相似文献

Food Aid, Food Prices, and Producer Disincentives in Ethiopia   总被引:1,自引:0,他引:1  
Although the short-term aims of food aid are well conceived, strong concerns have been voiced regarding the long-term impacts of such aid on incentives for agricultural producers in recipient countries. This article examines the statistical link between food aid shipments and food prices in Ethiopia over the period 1996–2006. Monthly data from three markets and three commodities are used to estimate a system of seemingly unrelated regression models for food prices. Results indicate that previous year food aid shipments reduce prices in all producer and consumer markets. These effects, however, appear to be limited to the set of internationally traded commodities that are domestically marketed. A recursive regression procedure is used to identify the food aid threshold at which a negative aid effect emerges. Food aid shipments that constitute less than 10% of domestic production appear to be benign, but shipments above this level show signs of being disruptive to local markets. We use a simple policy simulation to argue that production-sensitive targeting, e.g., conditioning food aid on local food production, would help to circumvent disincentive effects.  相似文献

With continually increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the world’s farmers are challenged to produce more food per hectare with less water, and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended/adapted to many other crops: wheat, maize, finger millet, sugarcane, tef, mustard, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. In this article, we review what is becoming known about various farmer-centred innovations for agroecological crop management that can contribute to agricultural sustainability. These changes represent the emerging system of crop intensification, which is being increasingly applied in Asian, African, and Latin American countries. More research will be needed to verify the efficacy and impact of these innovations and to clarify their conditions and limits. But as no negative effects for human or environmental health have been identified, making these agronomic options more widely known should prompt more investigation and, to the extent justified by results, utilization of these methodologies.  相似文献

This paper deals with the existence of private market suppliers in a standard local public goods model. The result of this modification can be a cycling process instigated by rich households rather than poor households. The theoretical model provides empirical implications for capitalization studies and policy implications for the provision and financing of local public goods including education.  相似文献

Distance in organizations   总被引:1,自引:0,他引:1  
There is perhaps no construct that is so fundamental to interpersonal interactions in organizations, yet so incompletely understood, than distance. Part of the difficulty in developing a comprehensive and informed understanding of the role distance plays in organizations is that theory and research in this area have been quite fragmented, focusing on narrow aspects of the construct and lacking the integration necessary to build a more general knowledge base. For example, Graen (1976) has contributed greatly to our understanding of one aspect of distance, presenting a model based on role theory whereby in-group and out-group members are hypothesized to enjoy different rewards, benefit from different leadership behaviors, and experience different levels of satisfaction and performance ratings based on relative closeness (or distance) in their working relationship with their supervisor. Other researchers have explored the phenomena of psychological distance (Rothaus, Morton, & Hanson 1965), spatial distance (Kerr & Jermier 1978; Ferris & Rowland 1985), and physical distance (Sundstrom, Burt, & Kamp 1980; Sundstrom 1986) in the supervisor-subordinate relationship. This research, although a good starting point, does not adequately define or integrate the various aspects of distance in organizations. This article represents an effort to develop a broader and more extensive understanding of the role distance plays in organizations by integrating the various types of distance into a theoretical model. A model of Dyadic Distance in the supervisor-subordinate relationship is presented which develops the new constructs of Dyadic, Psychological, Structural, and Functional Distance, examines their process dynamics and impact on Human Resource Management issues such as performance evaluations and turnover, and proposes needed directions for future research in this important area.  相似文献
