高职助产专业学生职业防护认知调查分析

为了解高职助产专业学生对职业防护的认知，给职业防护教育提供对策，采用问卷方式对黄石理工学院高职学院在校108名助产专业学生进行调查，结果为助产专业学生对职业防护的认识普遍较差。99．07％的学生认为开设职业教育课程很重要，且认为学校和医院应同时做好职业防护教育工作。提高助产专业学生的自我防护意识，降低危险因素对他们的伤害，学校、医院和带教教师对此问题应予以重视。     

Determinants of smallholder farmers' perceptions of risk in the Eastern Highlands of Ethiopia

This paper reports findings from a study of 178 farm households from two contrasting areas in the Eastern Highlands of Ethiopia. It examines risk perceptions of smallholder farmers under varying contexts. The study utilized both qualitative and quantitative methods of data collection and analysis. It was hypothesized that human capital and household characteristics and orientation, access to resources, infrastructure, information and environmental factors influence perceptions of risks in different ways. Data reduction for independent variables was done by factor analysis (principal component extraction method). Factor analyses identified factors influencing smallholder farmers' perceptions of sources of risks. Logistic regression analyses were used to study the relationships of identified principal components to perceived frequencies of occurrences and consequences of various sources of risks. Logistic regression analyses revealed that asset endowments, locational settings and livelihood diversification strategies pursued determine smallholders' perceived risks. Key findings from the informal survey point out differentiation in perceptions of causes and sources of risks by different actors.     

Welfare and quality improvement in an international market

This paper analyzes the optimal uniform and discriminatory quality requirements under Cournot competition when two firms produce high-quality and low-quality products, respectively, in an international market. The quality requirements in our paper are not set for the foreign firm but are set to regulate products of different qualities, since in the real world a domestic firm could be a high- or low-quality producer. We find that whether the government should raise the quality requirements depends on the type of competition in which firms engage and the adopted quality requirements. By and large, the government should always set quality requirements raising both firms’ quality directly or indirectly, regardless of the quality of the product of the domestic firm. However, if the domestic firm is a high-quality producer, the government should set a quality requirement that enables the domestic firm to monopolize the market when a discriminatory quality requirement is adopted, and should not set any quality requirement when a uniform quality requirement is adopted. Moreover, we show that the quality requirement can actually improve global welfare in most cases.     

Electronic Commerce Encourages Differentiation

Abstract

This paper explores why and how ecommerce firms differentiate their products and services. Consumers who shop online are able to do quick and easy comparison shopping, including shopping in an active market for used goods. Since online product search and price comparisons are faster, easier, and involve fewer shopping costs, firms who sell online must differentiate their products and services to a greater extent than those who do not sell online. These product and service differentiations may be certified and rated by host shopping sites and by outside ratings companies.     

广西城乡居民信息消费分化影响因素研究

根据消费理论及信息消费的特点,城乡居民信息消费分化是多因素综合作用的结果。5变量SVAR(2)模型的实证结果进一步表明收入分化和文化素质分化是信息消费分化最重要的两个内在影响因素,其贡献率分别为29%和28%;紧随其后的消费氛围分化与消费条件分化是不容忽视的外在因素,贡献率分别为20%和18%。显然,降低这些影响因素的分化程度是有效缓解城乡信息消费分化的关键。

Measuring Lifetime Redistribution in Dutch Occupational Pensions

Summary  This paper assesses how the Dutch system of occupational pensions redistributes between and within generations. The approach in this paper deviates from the usual approach by incorporating the full life cycle in the measurements, rather than only the annual effects. In order to quantify redistribution, we use the level of educational attainment, gender and age to classify the pension fund population. For all groups distinguished, we measure in present value terms the average net benefit from participating in occupational pensions. The results indicate a sizable redistribution from males to females and from low educated to higher educated workers. On a lifetime basis, the impact of intergenerational transfers is modest. I am grateful to the two anonymous referees, Ed Westerhout, Casper van Ewijk, Lex Meijdam, Yvonne Adema and Peter Kooiman for their helpful comments on earlier drafts of this paper, and to Andre Nibbelink for his valuable computational assistance.     

How much trustworthy and salubrious an organic jam should be? The impact of organic logo on the Italian jam market

This paper studies the impact of organic logo in the Italian jam market. Using data on true sales in Italian supermarkets in the 2002–2004 period we estimate the structural demand model developed by Berry (1994). This approach allows us to solve potential endogeneity problem in the estimation of the price coefficient in the demand equation, as well as other aspects related to multiple sources of differentiation. In a market where 62 percent of organic jams are diet this approach allows us to identify separately the market power induced by the organic logo and by the low content of sugar. The estimation results from various specifications of GEV class of models show that the organic attribute guarantees a degree of market power greater than the diet attribute. However, the protection from competition entailed by the organic logo is not particularly strong, and the diet attribute does not guarantees additional protection to organic jams. Most importantly, our findings show that consumers trust more big organic producers thus suggesting important policy implications on the supply and marketing side of the jam market.     

Product innovation and firms’ ownership

This paper explores (i) the incentives for an incumbent firm to acquire an entrant willing to sell a product innovation rather than openly competing with this entrant, and (ii) in case of acquisition, the incentives to sell simultaneously both the existing products and the new one rather than specializing on a single variant. We prove that, in some circumstances, an incumbent firm can find it profitable to make an acquisition proposal to the entrant. Nevertheless, in this acquisition scenario, a product proliferation strategy is never observed at equilibrium. Furthermore, while being available for sale, sometimes the innovation simply remains unexploited.
