Using an experimental methodology based on investment games, we examine whether smallholder rice farmers from Nueva Ecija, Philippines have heterogeneous preferences for improvements in 10 rice varietal traits. We use a latent class cluster approach to identify different segments of rice producing households and their distinct preferences for trait improvements. These clusters were characterised post hoc using household, farm, and marketing characteristics. On average, farmers invested the most in rice varietal trait improvements that offered opportunities to reduce losses caused by lodging, insects and diseases. We found four classes of farmers with distinct preferences for improvements in variety traits. The clusters were significantly different in terms of household and farm characteristics. These findings can guide breeding research in the development of varieties that have the traits farmers identified for improvement, and that will address the unique needs of distinct farmer segments.  相似文献

This article examines the behavior or long-run average cost when the firm knows it faces pecuniary economies or diseconomies or scale and has other than a constant-returns-to-scale production function. The central issue is the conditions under which the scale properties of the production function will or will not dominate the pecuniary effects of changing input prices.  相似文献

In a number of countries where health care is publicly funded, policies to introduce greater patient choice are being implemented. In most cases patient choice is seen as an instrument to reduce waiting times for elective (non-emergency) hospital services. An important issue is whether facilitating greater patient choice will increase the demand for health care and thereby undermine the achievement of reduced waiting times. A large scale pilot of choice in the London metropolitan area permits a test of the hypothesis that choice will affect demand. This paper estimates a model of the demand for elective surgery using a panel of 150 English acute hospitals over the period 1995 to 2004 for three surgical specialties. It examines whether demand shifted following the introduction of the London Patient Choice Project in 2002. The results suggest that the choice project only shifted NHS inpatient demand in orthopaedics and that this shift was inwards.  相似文献

A case is made that the adoption of IT in European retailing is inhearntly conservative and is not characterized by the rapid revolutionary change sometimes argued to be the case. Reasons are suggested for the slow rate of integration of IT into retail management process and the limited range of applications in use operationally. These reasons are considered as within the nature of IT and within the culture of retailing. The impact of IT in retailing is considered in respect of cost reduction, improved asset productivity, changing internal relationships and the changing external relationships of retailers. Some areas of potential research are listed.  相似文献

Hazen S. Pingree was a remarkable civic leader. In his four terms as mayor of Detroit from 1889 to 1897, Pingree lowered the cost of vital public utilities, including gas, lighting, and transit; modernized the city's sewage system; and rooted out corruption and dishonesty in municipal government. He successfully spearheaded the movement for the three‐cent streetcar fare and brought Detroit to the brink of public ownership and operation of its own transit system. Pingree's social reform program for Detroit centered around two interrelated urban reform movements gathering steam at the turn of the 20th century: the movement for municipal ownership and the movement to equalize taxes by increasing taxes on corporate property. Both of these movements drew heavily from Henry George's single tax. In particular, Pingree's efforts to secure a municipally owned and operated street railway system and effort to increase taxation on corporate property illustrate the ways in which turn‐of‐the‐20th‐century civic leaders drew from the rhetoric and substance of George's ideas to implement progressive urban reforms.  相似文献

Abstract

Progressing sustainable tourism requires both an innovative transition from “unsustainable” tourism and innovative research methods to develop theory and concepts for a sustainable tourism. While there are many ad hoc examples of initiatives, there are very few examples of firms systematically recording their medium-term evolutionary progress. This case study of an accommodation provider uses longitudinal data over 14 years, deductive and inductive methods, and comparison with other similar eco-friendly providers, to provide the first exploration of sustainability-oriented innovation by a firm attempting to make transitions. Findings show how important hindsight and insight are for continuous learning, and how broader community sustainability issues influence the owners’ worldviews. Both learning and changing views are required to support innovation. A Sustainability-oriented Service Innovation model is recommended, recognising the characteristics of a service industry where innovation can be an organic process led by humans for humans and consequently more fuzzy in its progress than the clearly defined steps that are suggested by previous research. This model seeks to assist researchers and practitioners to better measure innovative progress of service firms, and develop more relevant strategies to ease transitions towards sustainable business practices.  相似文献

This study examines whether sanctions imposed by the China Securities Regulatory Commission (CSRC) against individual auditors result in greater auditor conservatism. Using a difference-in-differences research design, we find that clients of sanctioned individual auditors have lower discretionary accruals in the post-sanction period than in the pre-sanction period when compared to a matched control group of clients audited by individual auditors who were not sanctioned. Our findings suggest that sanctions imposed by the CSRC on individual auditors can lead to improvements in audit quality by increasing the conservatism of the sanctioned auditors. That is, individual auditors are more likely to resist their clients’ income-increasing accounting manipulations after being sanctioned by the CSRC.  相似文献
