An incentive pricing with two types of qualities and users

This paper analyses quality discrimination when the monopolist provides two types of qualities for two-types of users, for example, in the software market. The users using software are confronted with two types of quality in using the software: one is related to learning, while the other is operation. In addition, the users are discriminated by the frequency of utilization for software, for example, low-demand and high-demand users. In this paper, the characteristics for bi-directional quality distortion in both learning quality and operation quality are analysed. It is shown that the distortion can occur both for low demanders and for high demanders. Finally, from public policy, a subsidy mechanism is introduced.     

工作生活质量的研究述评

工作生活质量是在社会技术系统理论的基础上,在员工需求发生极大变化的时候出现的新概念,并引起国内外学者的极大关注。学者们对工作生活质量的概念内涵、内容维度以及测量进行了大量研究,其中也存在不可忽视的问题：工作生活质量没有统一的概念,而且其内涵也过于空泛庞大;工作生活质量的内容维度模糊,独立性差;对工作生活质量的测度具有片面性,缺乏具有良好信度和效度的测量工具。     

基于公司治理的中小企业会计信息质量改进研究

论文首先简单介绍了公司治理理论的内容,然后分析了公司治理与会计信息质量之间的显著相关性,讨论了我国现阶段中小企业公司治理存在的问题及对会计信息质量的影响,最后从内、外部治理机制两方面分别提出了提高中小企业会计信息质量的对策,认为企业内部需要建立有效履行各个职能的运行机制,同时还需要政府、银行、社会中介和媒体等对外部治理发挥作用。     

Is participation in agri-environmental programs affected by liquidity and solvency?

Financial constraints, both in the short and long run, have an impact on economic well-being of farm families. Additionally, financial constraints have an impact on production efficiency and technology adoption. This study investigates factors affecting farmers’ participation in the agri-environmental programs like Conservation Reserve Program (CRP) and the Environmental Quality Incentives Programs (EQIPs) in the U.S. particular attention is given to the roles of liquidity and solvency on participation in CRP and EQIP. Results show that both liquidity and solvency have a negative impact on participation in such programs. Additionally, we found that access to the Internet plays an important role in the farmer's decision to participate in CRP and EQIP. Our results also suggested that beginning farmers are more likely to participate in EQIP program.     

质量的产能约束、信息不对称与大销量倾向:以食品安全为例

食品安全关系到每一个人的健康与生存,但以乳品为代表的食品类企业却往往忽视质量控制而热衷于销量扩张.本文从技术约束和信息不对称的角度对此给出了一种解释.分析表明:竞争压力未必是解释该现象的关键因素;只要产品的市场容量较大、并且在投资不足的前提下提供优质产品的产能相对较小,即使没有竞争的压力,厂商在质量控制上的投资也不充分,而且总是热衷于低价大销量的营销方式,后者被消费者视为投资充分的不完美信号.增强监管无法从根本上改变厂商投资不足且追逐大销量的现状,但能增加厂商高投资的可能性、提高产品的平均质量.我们的结论在一定程度上吻合乳品等国内食品企业高速扩张但忽视质量控制的现状.

Development and Psychometric validation of the Diabetes Therapy-Related QOL (DTR-QOL) Questionnaire

Abstract

Objective:

We developed and evaluated the psychometric properties of the Diabetes Therapy-Related QOL (DTR-QOL) as a disease-specific, self-administered questionnaire to assess the influence of diabetes treatment on patient QOL, regardless of treatment method.

Methods:

This new questionnaire was developed and validated in a standardized manner: Item development, pilot-testing and psychometric validation. A survey was conducted using the provisional version of the questionnaire, and reliability and validity were evaluated with psychometric testing.

Results:

The provisional version of the questionnaire was generated with 29 items through literature review and pilot testing. For psychometric assessment, analyses were performed on the responses of 284 adult Japanese patients with diabetes. Factor analysis by the principal factor method with promax rotation revealed 4 factors; “burden on social activities and daily activities” (13 items), “anxiety and dissatisfaction with treatment” (8 items), “hypoglycemia” (4 items), and “satisfaction with treatment” (4 items). For reliability, the intraclass correlation was 0.92, and Cronbach’s alpha coefficient was 0.94, indicating adequate test-retest reliability and internal consistency. For known-group validity, there were significant differences in scores for following variables: age, diabetes type, HbA1c, treatment method, glycemic control, hypoglycemia, nocturnal hypoglycemia, concern about weight gain, health status (patient assessment), and degree of communication with physician.

Conclusions:

The DTR-QOL, with good reliability and validity, can assess the influence of diabetes treatment on patient QOL. The DTR-QOL can be used regardless of treatment method that patients receive, and this characteristic enables to detect a difference on patients QOL between treatment methods before and after a switch of treatment. Limitations of this study include representativeness of the patient sample. The relatively small number of patients with type 1 diabetes should be noted. Also, responsiveness of the DTR-QOL has not yet been examined.     

Exchange rate pass-through and product heterogeneity: Does quality matter on the import side?

This paper investigates theoretically and empirically the heterogeneous response of exporters to real exchange rate fluctuations due to the quality of imported inputs and exported output. We develop a model where the production of high-quality products requires high-quality inputs sold in monopolistically competitive foreign markets. The model predicts that exporters using imported inputs have low exchange rate pass-through, but this effect is weaker for firms shipping high-quality goods. This is due to the heterogeneous price adjustments of foreign suppliers selling inputs of different quality. We test the predictions of the model using Italian firm-level trade data for the period 2000–2006. The empirical analysis shows that the imports of intermediates have a significantly weaker effect in reducing the exchange rate pass-through into the export price of high-quality varieties. By showing that the import price of high-quality inputs is less sensitive to exchange rate variations, we provide evidence supporting the theoretical hypothesis that the pricing power of input suppliers weakens the import channel.
