USING CONJOINT ANALYSIS TO PREDICT TRIAL AND REPEAT-PURCHASE PATTERNS OF NEW FREQUENTLY PURCHASED PRODUCTS*

A new approach is proposed to evaluate new-product opportunities. This approach uses the distribution of brand-purchase probability of the new product over a population of potential customers and the outputs from conjoint analysis. The heterogeneous distribution of brand-purchase probability is expressed by a beta binomial brand-choice model compounded with a negative binomial product-class purchase-incidence model. The resulting model provides a way to predict trial and repeat-purchase patterns of new-product concepts. The paper discusses the development of the model. It also discusses issues of measurement, estimation, testing, and implementation of the proposed approach based on actual empirical data.     

Visions in monochrome: families, marriage and the individualization thesis

This paper takes issue with the way in which the individualization thesis--in which it is assumed that close relationships have become tenuous and fragile--has become so dominant in 'new' sociological theorizing about family life. Although others have criticized this thesis, in this paper the main criticism derives from empirical research findings carried out with members of transnational families living in Britain whose values and practices do not fit easily with ideas of individualization. It is argued that we need a much more complex and less linear notion of how families change across generations and in time.

Smallholder Preferences for Agri‐environmental Change at the Bhoj Wetland,India

Incentive‐based approaches have gained policy interest in linking change in agricultural land management with environmental conservation. This article investigates how scheme design influences smallholder farmers' decisions to switch to organic farming to reduce water pollution, drawing on a study at a Ramsar wetland site providing water for the city of Bhopal. Results from a choice experiment suggest that transitional payments are necessary to overcome farmer constraints to adopt organic farming, and that effective land certification has the potential to act as a self‐enforcing mechanism linking farmer incomes with wetland conservation benefits.

A Faith‐Based Advantage?

This study explored whether religiously affiliated nonprofit schools participating in Milwaukee's long‐standing school voucher program engage in more fundraising and perform better on academic indicators than nonsectarian nonprofit schools. The analysis of three years of organizational‐level voucher school data reveals that a higher percentage of religious affiliated schools engage in fundraising, and that religious schools affiliated with umbrella organizations have higher test score indicators than nonsectarian schools. The author concludes that the religious advantage is likely in part a result of the broader access to networks and resources available to religious schools associated with umbrella organizations like a Catholic archdiocese or Lutheran synod. The results are relevant to policymakers who are considering implementing a reinvented government approach to the provision of public goods, as well as leaders of nonprofit corporations who seek to maximize performance.

新公司法忽视的重要视角:劳动与资本

2006年1月1日开始实施的新公司法对中小股东加大了保护力度,但是,对公司中两大基本要素之一的劳动者没有给予应有的关注,尤其对劳动权力更是只字未提①。劳动和资本是公司的两大基本关系,因此,充分重视劳动权力,提升劳动权力的地位,使劳动权力与资本权力在公司中处于对应的位置,是现代社会中公司生死存亡的生命线。正确树立企业劳动与资本调节机制所依据的基本理念,研究调节机制的路径选择是完善公司治理、构建和谐劳动关系的关键。
