Food safety regulation,economic impact assessment and quantitative methods

Together with a call for more efficient regulations in the EU, there is a growing demand for transparency in the evaluation techniques to assess and predict their effects. This article explores the potential impacts of food safety regulations and discusses the quantitative methods used in the policy evaluation literature. Along with the strengths and limitations of each method, this review highlights other transversal issues relevant to the assessment strategies. Among these are the imbalance between ex ante and ex post evaluation, the lack of adequate data, the difficulty of estimating the dynamic effects of regulations, and the possibility of endogenous relationships.     

对签约与违约的经济分析

合同是一种双方当事人在平等自愿的基础上达成一致的协议,签约和违约则是当时人在合同的发生过程中经常出现的两种情况。本文从经济学的角度,对合同法中的签约与违约进行了分析,具体分析了相关的成本思想,得出结论:要强化信誉观念,减少交易成本。同时还指出效率违约理论是合同法历史发展的结果,将效率从经济学领域引入到合同法领域。     

International alliance commitment and performance of small and medium-size enterprises: The mediating role of process control

Improving alliance performance is a critical issue that both managers and researchers have attempted to resolve. Recently scholars have suggested that firms can use alliance commitment and process controls to improve alliance performance. Yet research has only found weak support for these direct effects. In this paper we examine the mediating role of process controls on the relationship between alliance commitment and alliance performance. When tested on samples of SMEs we find support for our theoretical predictions. We then discuss the managerial implications of using commitment and process controls in SME international alliances.     

“…and they are really lying”: Clean evidence on the pervasiveness of cheating in professional contexts from a field experiment

We investigate the pervasiveness of lying in professional contexts such as insurance fraud, tax evasion and untrue job applications. We argue that lying in professional contexts share three characterizing features: (1) the gain from the dishonest behavior is uncertain, (2) the harm that lying may cause to the other party is only indirect and (3) lies are more indirect lies by action or written statements. Conducted as a field experiment with a heterogenous group of participants during a University “Open House Day”, our “gumball-machine-experiment” provides field evidence on how preferences for lying are shaped in situations typically found in professional contexts which we consider to be particularly prone to lying behavior compared to other contexts. As a key innovation, our experimental design allows measuring exact levels of cheating behavior under anonymous conditions. We find clean evidence that cheating is prevalent across all sub groups and that more than 32% of the population cheats for their own gain. However, an analysis of the cheating rates with respect to highest educational degree and professional status reveals that students cheat more than non-students. This finding warrants a careful interpretation of generalizing laboratory findings with student subjects about the prevalence of cheating in the population.     

To live an ordinary life: resource needs and additional costs for people with a physical impairment

Disabled people face increased risks of living in poverty largely due to lower incomes and extra resource requirements compared to non-disabled people. This study incorporated the social model of disability with an economic approach to costing to estimate the additional costs required by people with a physical impairment to achieve an adequate standard of living in New Zealand. Budgets estimating the additional equipment, modifications, transport, support and time required to achieve an adequate standard of living were developed and validated through focus groups with community members. The findings suggest that reducing barriers involves substantial costs ranging from NZ$645–$2,348 per week.     

Priority Rules for Multi‐Task Due‐Date Scheduling under Varying Processing Costs

We study the scheduling of multiple tasks under varying processing costs and derive a priority rule for optimal scheduling policies. Each task has a due date, and a non‐completion penalty cost is incurred if the task is not completely processed before its due date. We assume that the task arrival process is stochastic and the processing rate is capacitated. Our work is motivated by both traditional and emerging application domains, such as construction industry and freelance consulting industry. We establish the optimality of Shorter Slack time and Longer remaining Processing time (SSLP) principle that determines the priority among active tasks. Based on the derived structural properties, we also propose an effective cost‐balancing heuristic policy and demonstrate the efficacy of the proposed policy through extensive numerical experiments. We believe our results provide operators/managers valuable insights on how to devise effective service scheduling policies under varying costs.

Old and Cold: Older People and Policies Failing to Address Fuel Poverty

Research, funded by the British Gas Help the Aged Partnership and carried out by the Institute of Gerontology, King's College London, explored the multidimensional issues of fuel poverty. A sample of older homeowners and private renters living in England, Scotland and Wales were interviewed in the Spring of 2003 to explore their experiences of keeping their homes warm in the preceding winter. It was found that almost half of the sample for whom full information was available were in fuel poverty. Government schemes failed to address some important issues. Grants were only available to those with “passport benefits”, excluding those who had minimal occupational pensions. Although most respondents had central heating, it was often old and ineffective, yet grants were not available to modernize them. Government schemes did not extend to paying for external and internal insulation for solid wall properties yet many older people live in such property. Several older people lived in rural areas not connected to mains gas. As mains gas currently provides the cheapest fuel, they faced high bills, yet government policies do not address the differential fuel costs in these areas. The culture of many older people in the study contributed to their living in cold homes. They lived frugally and usually turned heating off in daylight hours during winter. It was also a common practice to sleep in an unheated bedroom during winter and to keep the window open at night. Such practices are acknowledged to be unhealthy.     

Five tumultuous years in Australian child protection: little progress

In an article published in 2002, one of the authors of this paper offered an analysis of the Australian child protection data from 1999 to 2000 and raised questions about the effectiveness of mandatory reporting. Recently, child protection data for 2003–2004 has been released. This provides an opportunity to re‐examine some child protection issues and the effectiveness of mandatory reporting 5 years on. These have been tumultuous years. Each state and territory has held major inquiries into this area of practice and, as a result, significant organizational changes have taken place and new resources are being made available. Nevertheless, questions about the effectiveness of child protection services remain. There is continuing doubt about the value of comprehensive reporting systems.
