There is a large and fragmented literature that examines the nature of franchising. This paper aims to collect all the empirical evidence on the factors that make franchising work and to integrate this evidence in a framework. A narrative synthesis was performed of 126 peer‐reviewed empirical journal articles. This review shows how the outcomes of franchising are determined by five major clusters of factors: ownership structure, business format design, contract design, behavior of the franchisor and the franchisee and their interaction, and the age and size of the system and its units. It identifies what franchisors and franchisees need to do to be successful and which evidence gaps and conflicting results remain. To yield better outcomes for both the franchisor and the franchisee, they should work on a recognizable brand name and a good working relationship; in addition, they should have suitable skills and attitudes as well as contractual exclusive territories. For further improvement of franchisee outcomes, high‐quality franchisor support, decentralized decision‐making, selection tools and fair contracts are essential. The effects of a high franchise proportion, active ownership, knowledge exchange and standardized operating instructions are contingent on other structural and contextual factors in the system. Conflicts and tying should be prevented. Hardly any research has been undertaken into which franchise designs are valued by customers. The authors have launched a research agenda for further research, from various theoretical perspectives, into the interactions between system elements, actors and contexts.  相似文献

The aim of this paper is to test the connections between the indicators used in the literature on social cohesion, which usually reflect ‘general’ values or behaviours, and indicators specific to a particular space, namely the labour market. A key question is the stability of the social cohesion’s indicators when moving from a societal level to the labour market. Based on data from the World Value Survey, and following a restrictive definition of social cohesion, a comparison is done, for European countries. Examination of the situation in the two spheres makes it possible to identify more or less homogeneous groups of countries and also to point to instabilities. ‘Regimes’ of social cohesion begin to emerge. As in most analyses, the Nordic countries (excluding Finland) have high scores in all the dimensions. Conversely, most of the new EU member states from the former Eastern bloc have low scores, particularly in the horizontal dimension of trust between individuals.  相似文献

This paper studies the nonparametric identification of a contract model with adverse selection and moral hazard. Specifically, we consider the false moral hazard model developed by Laffont and Tirole (1986). We first extend this model to allow for general random demand and cost functions. We establish the nonparametric identification of the demand, cost, deterministic transfer, and effort disutility functions as well as the joint distribution of the random elements of the model, which are the firm's type and the demand, cost, and transfer shocks. The cost of public funds is identified with the help of an instrument. Testable restrictions of the model are characterized.  相似文献

A novel approach to the quantitative assessment of food-borne risks is proposed. The basic idea is to use Bayesian techniques in two distinct steps: first by constructing a stochastic core model via a Bayesian network based on expert knowledge, and second, using the data available to improve this knowledge. Unlike the Monte Carlo simulation approach as commonly used in quantitative assessment of food-borne risks where data sets are used independently in each module, our consistent procedure incorporates information conveyed by data throughout the chain. It allows "back-calculation" in the food chain model, together with the use of data obtained "downstream" in the food chain. Moreover, the expert knowledge is introduced more simply and consistently than with classical statistical methods. Other advantages of this approach include the clear framework of an iterative learning process, considerable flexibility enabling the use of heterogeneous data, and a justified method to explore the effects of variability and uncertainty. As an illustration, we present an estimation of the probability of contracting a campylobacteriosis as a result of broiler contamination, from the standpoint of quantitative risk assessment. Although the model thus constructed is oversimplified, it clarifies the principles and properties of the method proposed, which demonstrates its ability to deal with quite complex situations and provides a useful basis for further discussions with different experts in the food chain.  相似文献

This review offers an update of the psychological effects of Tai Chi Chuan (TC) among different populations. A computerized literature research from 1990 to June 2006 was carried out. Studies were selected when they assessed the mental and psychological effects of TC practice among various populations. Data from 14 studies for a total of 829 subjects, age range from 12 to 96 years, were considered here. There were eight randomized controlled trials and six quasi-experimental or case control studies in this review. The intensity of TC varied from 30 min twice a week over a 5-week period to 1 h every day over an 8-week period. TC was characterized as a kind of light-to-moderate exercise and was found to enhance overall psychological well-being and to improve self-efficacy and mood. TC benefits appeared to be more tangible for adults and healthy older adults or those becoming frail. However, TC did not appear to be more efficient than exercises of the same intensity. Extensive and qualitative studies are needed to quantify the effects of the volume of practice, expert modeling, gender differences, and the age-related learning process on efficacy cognitions and mood in clinical and nonclinical contexts.  相似文献

As gambling facilities become more available, the number of pathological gamblers increases. Effective therapeutic and preventive interventions should be developed and systematically evaluated. Self-exclusion programs may be a useful means to facilitate self-control among problem gamblers. This paper describes the characteristics of individuals who decided to bar themselves from a Canadian casino. Two hundred twenty individuals participated in the present study and completed a questionnaire including four sections: (1) socio-demographic data, (2) the South Oaks Gambling Screen, (3) gambling habits, and (4) prior experiences with the self-exclusion program. According to the SOGS, 95% of the participants were classified as severe pathological gamblers on the SOGS (Mean score = 9.87). Furthermore, based on self-reported observation, 30% of the participants completely stopped gambling once enrolled in this program. No one scored within the interval of non-problem gamblers. Suggestions to improve self-exclusion programs are discussed.  相似文献
