Public Report,Price, and Quality

A monopolist produces a good with two qualities. All consumers have the same valuation of the first quality, but their valuations of the second vary, and are their private information. A public agency can verify qualities, and make credible reports to consumers. In Full Quality Report, the public agency reports both qualities. In Average Quality Report, it reports a weighted average of qualities. The equilibrium prices and qualities in Full Quality Report can be implemented by Average Quality Report. Equilibrium prices and qualities in Average Quality Report give higher consumer surplus than Full Quality Report. Bertrand competition under Average Quality Report yields first‐best prices and qualities.     

OHSAS 18001 certification and operating performance: The role of complexity and coupling

Today, manufacturing firms encounter pressure from multiple stakeholders to manage occupational health and safety issues properly, systematically and transparently. While manufacturing firms commonly use internally developed Occupational Health and Safety Management Systems, there is growing pressure to adopt externally certified system such as OHSAS 18001. However, there are conflicting views and little empirical evidence that examines the linkage between OHSAS 18001 certification and operating performance. Hence, this paper examines the impact of OHSAS 18001 on operational performance through three theoretical lenses: Institutional Theory, Normal Accident Theory, and High Reliability Theory. We also investigate how complexity and coupling moderate the relationship between OHSAS 18001 and operational performance. Based on a sample of 211 U.S. listed manufacturing firms with OHSAS 18001 certification, we find that certification leads to significant increases in abnormal performance on safety, sales growth, labor productivity, and profitability and that these benefits increase as complexity and coupling increase.     

Can oil-rich countries encourage entrepreneurship?

This study provides the first empirical investigation to test one of transmission channels of resource curse, i.e. marginalized entrepreneurship activities. Our panel data analysis of 65 countries from 2004 to 2011 shows a negative and statistically significant association between oil rents dependency and entrepreneurship indicator. This finding is robust to control of other major drivers of entrepreneurship, unobservable country- and time-fixed effects and a different measurement of oil rents dependency. In addition, our main results show that government effectiveness among other dimensions of good governance has a statistically significant moderating effect in entrepreneurship–oil rents nexus.     

Ingredient Optimization and Children’s Liking of Popcorn Seasoned with Fish Protein Powder/Omega-3 Fish Oil

Response surface methodology (Box-Behnken design) was used to optimize the seasoning ingredients of popped popcorn. Children’s liking of seasoned popcorn was also determined by 120 school children. The results indicated that seasoning of popcorn with fish protein powder and omega-3 fish oil could produce accepted snacks that would be more nutritious than the widely consumed regular popcorn. Fortification of popcorn with 9% fish protein powder and/or 6% omega-3 fish oil did not influence the sensory attributes of the prototypes. Liking test revealed that children in the age range of 6 to 12 years liked the selected fortified products. This fortification also provided another avenue for cereal snack food diversification and might be a healthy option to boost children’s nutritional intake and to increase fish protein consumption. Such products are good choices for health-conscious consumers.     

金融科技创新的包容审慎监管研究

摘要：金融作为现代经济的核心,能够有效促进农村产业发展。近年来,重庆农业生产能力不断增强、生产条件明显改善,新产业新业态蓬勃发展。但是金融在支持农村产业发展过程中仍然存在金融产品形式单一、信用体系不健全等问题,无法完全满足农村产业发展的资金需求,制约重庆农村产业的高质量发展。本文结合重庆金融支持农村产业发展的现状、实践模式与现实困境,从聚焦优势特色产业、优化农产品加工产业结构、推进科技赋能农村金融和健全农村信用体系四个方面提出重庆金融支持农村产业发展的路径优化策略,以期为金融支持农村产业发展提供一定的参考。     

Foreign direct investment in China: Policy,recent trend and impact 1

One of the most important elements of China's economic reform has been the promotion of foreign direct investment (FDI) inflow. Government polices on FDI have gone through different stages in their main objectives since the late‐1970s, from gradually opening to foreign investors, to actively encouraging inward investment, directing FDI in accordance with domestic industrial restructuring, and complying with China's World Trade Organization (WTO) obligations. FDI in China has experienced rapid growth especially since the mid‐1990s, as well as structural change. Most of the earlier investments were small scale, labor‐intensive and export‐oriented. In recent years, more investment has been large scale and more capital and technology intensive, aiming at both domestic and export markets. Moreover, increasingly more investment has come from the industrial world, and has located along the eastern coastal regions, in additional to the two southeastern provinces. FDI has played a crucial role in China's rapid growth, economic transition, and, mostly importantly, integration with the world. China's recent accession to the WTO provides more incentives to foreign investors. At the same time, it will also result in more intense competition for domestic firms.     

南非地下水管理的广泛内容

南非的地下水管理经过1998年国家颁布的水法得到了改善，即在南非政府的管理下，将目前国家水资源管理不完善的状态向水资源管理一体化发展。地下水管理将从一种高度集中的管理形式转变到这样一种状况：即地下水将在全国各流域管理系统中发挥其独特的作用，同时各用水户之间将通过一种创新的方式联系在一起，这种方式就是共享各相关政府部门及个人的供水量、资源量及信息等内容。     

Estimating the economic cost of weeds in Australian annual winter crops

An analysis of the annual costs of weeds in seven winter crops across Australia demonstrated that the most important 15 weed species cause substantial annual costs in both financial and economic terms. Using survey data captured over the 1998–1999 growing season, the financial cost of these weeds in seven crops was estimated to be AU$1,182 million. The main components of this cost were herbicides (AU$571 million), the competitive effects of residual weeds (AU$380 million), and tillage (AU$206 million) while weed contamination of grain was a minor cost (AU$25 million). Across all regions, the most economically important weeds were annual ryegrass, wild oats, and wild radish, although there were regional differences in importance. An economic surplus analysis determined the annual economic cost of weeds in annual winter crops to be AU$1,279 million. This surplus loss represented 17% of the gross value of Australian grain and oilseed production in 1998–1999. Australian grain producers incurred a major loss, with a reduction in producer surplus of AU$1,047 million. Australian grain consumers had a large consumer surplus loss (AU$229 million), while international consumers suffered a small loss and international grain producers gained a small producer surplus from the higher grain prices.
